Objective To compare the safety and efficacy of the dipeptidylpeptidase-4 ( DPP-4 ) inhibitors in patients with type 2 diabetes and inadequate glycemic control . Design Systematic review of r and omized controlled trials ( RCTs ) , health economic evaluation studies , systematic review s , and meta-analyses , followed by primary Bayesian mixed treatment comparison meta-analyses ( MTCs ) , and secondary frequentist direct-comparison meta-analyses using a r and om-effects model . Outcomes were reported as weighted mean change from baseline , or odds ratio ( OR ) with 95 % credible interval . Data sources MEDLINE , MEDLINE In-Process , EMBASE , and BIOSIS via Dialog ProQuest ; Cochrane Central Register of Controlled Trials and Cochrane Data base of Systematic Review s via EBSCO ; four diabetes and two technical congress abstract s ; and health technology assessment organization websites . Eligibility criteria Patients with type 2 diabetes and inadequate glycemic control receiving any pharmacological anti-diabetic treatment . Data extraction and analysis Title/ abstract s were review ed for eligibility , followed by full-text review of publications remaining after first pass . A three-person team filtered articles and an independent review er checked a r and om selection ( 10 % ) of filtered articles . Data extraction and quality assessment of studies were also independently review ed . Five DPP-4 inhibitors ( alogliptin , linagliptin , saxagliptin , sitagliptin , and vildagliptin ) were compared via meta- analysis ( where data were available ) as monotherapy , dual therapy ( plus metformin , sulfonylurea , pioglitazone , or insulin ) , and triple therapy ( plus metformin/sulfonylurea ) . Results The review identified 6,601 articles ; 163 met inclusion criteria and 85 publications from 83 RCTs contained sufficient or appropriate data for analysis . MTCs demonstrated no differences between DPP-4 inhibitors in mean change from baseline in glycosylated hemoglobin ( HbA1c ) or body weight , or the proportions of patients achieving HbA1c < 7 % or experiencing a hypoglycemic event , apart from in patients on alogliptin plus metformin , who achieved HbA1c < 7 % more frequently than those treated with saxagliptin plus metformin [ OR 6.41 ( 95 % CI 3.15–11.98 ) versus 2.17 ( 95 % CI 1.56–2.95 ) ] . Conclusions This systematic review and MTC showed similar efficacy and safety for DPP-4 inhibitors as treatment for type 2 diabetes , either as monotherapy or combination therapy Background Digital interventions provide effective and potentially cost-effective models for improving health outcomes as they deliver health information and services that are widely disseminated , confidential , and can be tailored to needs of the individual user . Digital interventions have been used successfully for health promotion , mental health , and for enabling self-management of long-term conditions . However , their effectiveness is limited by low usage rates , with non-engagement a major challenge . Hence , it is crucial to find effective strategies to increase user engagement with digital interventions . Objective This systematic review will aim to evaluate the effectiveness of technology-based strategies  to promote engagement with digital interventions . Methods We will follow Cochrane Collaboration guidelines on systematic review methodology . The search strategy will be executed across seven e- data bases ( including MEDLINE , EMBASE , PsycINFO , CINAHL ) using the concepts “ digital intervention ” and “ engagement ” , limited by study type ( r and omized controlled trial ) . Grey literature and reference lists of included studies will be search ed . Titles and abstract s will be independently screened by 2 authors . Then the full text of potentially eligible papers will be obtained and double screened . Data from eligible papers will be extracted by 1 author and checked for accuracy by another author . Bias will be assessed using the Cochrane bias assessment tool . Narrative synthesis will report on all included studies , and where appropriate , data will be pooled using meta- analysis . All findings will be reported according to the Preferred Reporting Items for Systematic Review s and Meta-Analyses guidelines . Sources of heterogeneity will be further investigated if required . Results Our research is in progress . The final draft of the systematic review is being written and will be su bmi tted before the end of 2015 . Conclusions The review findings will inform research ers and digital intervention providers about optimal use of technology-based strategies to promote engagement with digital interventions . Trial Registration PROSPERO International Prospect i ve Register of Systematic Review s : CRD42014010164 ; http://www.crd.york.ac.uk/ PROSPERO /display_record.asp?ID = CRD42014010164#.VTZmmiFViko ( Archived by WebCite at http://www.webcitation.org/6XxQC8fT8 ) Background To improve quality of care and patient outcomes , health system decision-makers need to identify and implement effective interventions . An increasing number of systematic review s document the effects of quality improvement programs to assist decision-makers in developing new initiatives . However , limitations in the reporting of primary studies and current meta- analysis methods ( including approaches for exploring heterogeneity ) reduce the utility of existing syntheses for health system decision-makers . This study will explore the role of innovative meta- analysis approaches and the added value of enriched and up date d data for increasing the utility of systematic review s of complex interventions . Methods / Design We will use the data set from our recent systematic review of 142 r and omized trials of diabetes quality improvement programs  to evaluate novel approaches for exploring heterogeneity . These will include exploratory methods , such as multivariate meta-regression analyses and all-subsets combinatorial meta- analysis . We will then up date our systematic review to include new trials and enrich the data set by surveying authors of all included trials . In doing so , we will explore the impact of variables not , reported in previous publications , such as details of study context , on the effectiveness of the intervention . We will use innovative analytical methods on the enriched and up date d data set to identify key success factors in the implementation of  quality improvement interventions  for diabetes . Decision-makers will be involved throughout to help identify and prioritize variables to be explored and to aid in the interpretation and dissemination of results . Discussion This study will inform future systematic review s of complex interventions and describe the value of enriching and updating data for exploring heterogeneity in meta- analysis . It will also result in an up date d comprehensive systematic review of diabetes quality improvement interventions that will be useful to health system decision-makers in developing interventions to improve outcomes for people with diabetes . Systematic review registration PROSPERO registration no. Background : Type 2 diabetes mellitus ( T2DM ) is becoming a leading problem worldwide . Emerging reports reveal alarming evidence of increasing prevalence of T2DM that has reached p and emic levels . Despite the significant incidence , there are limited reliable data re sources and comprehensive systematic review and meta- analysis on the effects of yoga on people who are a prediabetic or high risk for developing T2DM . Objective : The objective of this protocol is to conduct a full-scale systematic review and meta-analyses on the effects of yoga on people who are prediabetes or high risk of developing T2DM . Methods : The articles enrolled in the study will be retrieved from the online data bases between 2002 and the date the search es are executed . The search es will be repeated just before the final analyses and further relevant studies for inclusion . We will conduct a bibliographic search in data bases : Medline / PubMed , Scopus , Cochrane Library , EBSCO , and IndMED using keywords including prediabetes state , high risk for diabetes , metabolic syndrome , and yoga . A defined search strategy will be implemented along with selection criteria to obtain full-text articles of relevant studies . This study protocol was prepared according to the Preferred Reporting Items for Systematic Review s and Meta- Analysis for Protocol s 2015 guidelines . There will be no language restrictions . Ethics and dissemination : The proposed study will be based on published studies and publicly available anonymized data without directly involving human participants and therefore requires neither formal human ethical review nor approval by a human research ethics committee . We published an outline of the protocol in the International Prospect i ve Register of Systematic Review s ( PROSPERO ) in 2018 . We plan to disseminate the findings of this systematic review and meta- analysis through publication in a peer- review ed journal and presentation at relevant conference proceedings . In addition , we believe the results of the systematic review will have implication s for policy and practice . We will prepare policymaker summary using a vali date d format , disseminate through social media and email discussion groups . Review registration number : PROSPERO registration number CRD Systematic review s , a cornerstone of evidence -based medicine , are not produced quickly enough to support clinical practice . The cost of production , availability of the requisite expertise and timeliness are often quoted as major contributors for the delay . This detailed survey of the state of the art of information systems design ed to support or automate individual tasks in the systematic review , and in particular systematic review s of r and omized controlled clinical trials , reveals trends that see the convergence of several parallel research projects . We surveyed literature describing informatics systems that support or automate the processes of systematic review or each of the tasks of the systematic review . Several projects focus on automating , simplifying and /or streamlining specific tasks of the systematic review . Some tasks are already fully automated while others are still largely manual . In this review , we describe each task and the effect that its automation would have on the entire systematic review process , summarize the existing information system support for each task , and highlight where further research is needed for realizing automation for the task . Integration of the systems that automate systematic review tasks may lead to a revised systematic review workflow . We envisage the optimized workflow will lead to system in which each systematic review is described as a computer program that automatically retrieves relevant trials , appraises them , extracts and synthesizes data , evaluates the risk of bias , performs meta- analysis calculations , and produces a report in real time Introduction Hearing loss is a major public health concern , affecting over 11 million people in the UK . While hearing aids are the most common clinical intervention for hearing loss , the majority of people that would benefit from using hearing aids do not take them up . Recent technological advances have led to a rapid increase of alternative listening devices to conventional hearing aids . These include hearing aids that can be customised using a smartphone , smartphone-based ‘ hearing aid ’ apps , personal sound amplification products and wireless hearing products . However , no systematic review has been published evaluating whether alternative listening devices are an effective management strategy for people with hearing loss . Methods and analysis The objective of this systematic review is to assess whether alternative listening devices are an effective intervention for adults with hearing loss . Methods are reported according to the Preferred Reporting Items for Systematic review s and Meta-analyses Protocol s ( PRISMA -P ) 2015 checklist . Retrospective or prospect i ve studies , r and omised controlled trials , non-r and omised controlled trials , and before-after comparison studies will be eligible for inclusion . We will include studies with adult participants ( ≥18 years ) with a mild or moderate hearing loss . The intervention should be an alternative listening device to a conventional hearing aid ( comparison ) . Studies will be restricted to outcomes associated with the consequences of hearing loss . We will search relevant data bases to identify published , completed but unpublished and ongoing trials . The overall quality of included evidence will be evaluated using the GRADE system , and meta- analysis performed if appropriate . Ethics and dissemination No ethical issues are foreseen . The findings will be reported at national and international conferences , primarily audiology , and ear , nose and throat , and in a peer- review ed journal using the PRISMA guidelines . Review registration number PROSPERO CRD4201502958 AIMS To analyse the effect on systematic review s in diabetes interventions of including only trials that are indexed in medline , and to assess the impact of adding trials from other data bases and the grey literature . METHODS All systematic review s of diabetes interventions which included a meta- analysis of r and omized controlled trials , and were published since 1996 , were selected . The impact on the meta- analysis of including only those trials indexed in medline , and the effect of then adding trials from other sources , was assessed . Where possible this was measured quantitatively , by redoing the meta- analysis , otherwise a qualitative estimate was made . RESULTS Forty-four systematic review s met our inclusion criteria . There were 120 articles reporting trial data which were not indexed in medline . These came from 52 % of the review s. In 34 % of the review s , basing a meta- analysis on a search of only medline would miss trials that could affect the result . Sources of non- medline data which had the biggest effect on the meta-analyses were journal articles from central and embase ( mainly in Diabetes , Nutrition and Metabolism ) and unpublished data ( mainly from industry ) . The exceptions were journal articles on herbal medicine , mostly indexed in Chinese language data bases . CONCLUSIONS A search of only the medline data base is insufficient for systematic review s of diabetes , because in about 34 % of review s the missed trials could affect the results of the meta- analysis . It is recommended that central ( on the Cochrane Library ) also be search ed . Scanning meeting abstract s , and seeking unpublished data are also recommended if the intervention has only recently been introduced Background There is increasing pressure to address the social determinants of health ( SDoH ) and health inequities through the implementation of culturally acceptable interventions particularly in Sub-Saharan Africa ( SSA ) where health outcomes are generally poor . Available evaluation research on cash transfers ( CTs ) suggests that the programs may influence the wider determinants of health in SSA ; yet , there has been no attempt to synthesize the evidence regarding their contribution to tackling the SDoH and health inequalities . To date , nearly all the review s on CTs ' impact on health have predominantly featured evidence from Latin America with limited transferability to the social , cultural , and political environments in SSA . Therefore , the aim of this study is to undertake a systematic review to assess the role of CTs in tackling the wider determinants of health and health inequalities in SSA . Methods / design A systematic review of published and unpublished literature on CTs ’ impact on health and health determinants covering the period 2000–2016 will be undertaken . Studies will be considered for inclusion if they present quantitative or qualitative data , including all relevant study design s. The SDoH conceptual framework will be used to guide the data extraction process . EPPI Review er software will be used for data management and analysis . Studies included in the review will be analyzed by narrative synthesis and /or meta- analysis as appropriate for the nature of the data retrieved . Discussion This review will provide empirical evidence on the impact of CTs on SDoH to inform CT policy , implementation , and research in SSA . The protocol follows the Preferred Reporting Items for Systematic Review and Meta- Analysis Protocol s ( PRISMA -P ) . Systematic review registration This protocol has been registered with the PROSPERO international prospect i ve register of systematic review s , reference CRD42015025015 UNLABELLED In June 2008 , the Medical Advisory Secretariat began work on the Diabetes Strategy Evidence Project , an evidence -based review of the literature surrounding strategies for successful management and treatment of diabetes . This project came about when the Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the Ministry 's newly released Diabetes Strategy .After an initial review of the strategy and consultation with experts , the secretariat identified five key areas in which evidence was needed . Evidence -based analyses have been prepared for each of these five areas : insulin pumps , behavioural interventions , bariatric surgery , home telemonitoring , and community based care . For each area , an economic analysis was completed where appropriate and is described in a separate report .

CLINICAL NEED TARGET POPULATION AND CONDITION Diabetes ( i.e. diabetes mellitus ) is a highly prevalent chronic metabolic disorder that interferes with the body 's ability to produce or effectively use insulin . The majority ( 90 % ) of diabetes patients have type 2 diabetes . ( 1 ) Based on the United Kingdom Prospect i ve Diabetes Study ( UKPDS ) , intensive blood glucose and blood pressure control significantly reduce the risk of microvascular and macrovascular complications in type 2 diabetics . While many studies have documented that patients often do not meet the glycemic control targets specified by national and international guidelines , factors associated with glycemic control are less well studied , one of which is the provider(s ) of care . Multidisciplinary approaches to care may be particularly important for diabetes management . According guidelines from the Canadian Diabetes Association ( CDA ) , the diabetes health care team should be multi- and interdisciplinary . Presently in Ontario , the core diabetes health care team consists of at least a family physician and /or diabetes specialist , and diabetes educators ( registered nurse and registered dietician ) . Increasing the role played by allied health care professionals in diabetes care and their collaboration with physicians may represent a more cost-effective option for diabetes management . Several systematic review s and meta-analyses have examined multidisciplinary care programs , but these have either been limited to a specific component of multidisciplinary care ( e.g. intensified education programs ) , or were conducted as part of a broader disease management program , of which not all were multidisciplinary in nature . Most review s also do not clearly define the intervention(s ) of interest , making the evaluation of such multidisciplinary community programs challenging . EVIDENCE -BASED ANALYSIS METHODS RESEARCH QUESTIONS What is the evidence of efficacy of specialized multidisciplinary community care provided by at least a registered nurse , registered dietician and physician ( primary care and /or specialist ) for the management of type 2 diabetes compared to usual care ? [ Henceforth referred to as Model 1]What is the evidence of efficacy of specialized multidisciplinary community care provided by at least a pharmacist and a primary care physician for the management of type 2 diabetes compared to usual care ?

SEARCH STRATEGY A literature search was performed on September 28 , 2008 using OVID MEDLINE , MEDLINE In-Process and Other Non-Indexed Citations , EMBASE , the Cumulative Index to Nursing & Allied Health Literature ( CINAHL ) , the Cochrane Library , and the International Agency for Health Technology Assessment ( INAHTA ) for studies published between January 1 , 2000 and September 28 , 2008 . Abstract s were review ed by a single review er and , for those studies meeting the eligibility criteria , full-text articles were obtained . Reference lists were also examined for any additional relevant studies not identified through the search . Articles with unknown eligibility were review ed with a second clinical epidemiologist , then a group of epidemiologists until consensus was established . The quality of evidence was assessed as high , moderate , low or very low according to GRADE methodology . Given the high clinical heterogeneity of the articles that met the inclusion criteria , specific models of specialized multidisciplinary community care were examined based on models of care that are currently being supported in Ontario , models of care that were commonly reported in the literature , as well as suggestions from an Expert Advisory Panel Meeting held on January 21 , 2009 . SUMMARY OF FINDINGS The initial search yielded 2,116 unique citations , from which 22 RCTs trials and nine systematic review s published were identified as meeting the eligibility criteria . Of these , five studies focused on care provided by at least a nurse , dietician , and physician ( primary care and /or specialist ) model of care ( Model 1 ; see Table ES 1 ) , while three studies focused on care provided by at least a pharmacist and primary care physician ( Model 2 ; see Table ES 2 ) . Based on moderate quality evidence , specialized multidisciplinary community care Model 2 has demonstrated a statistically and clinical ly significant reduction in HbA1c of 1.0 % compared with usual care . The effects of this model on SBP , however , are uncertain compared with usual care , based on very-low quality evidence . Specialized multidisciplinary community care Model 2 has demonstrated a statistically and clinical ly significant reduction in both HbA1c of 1.05 % ( based on high quality evidence ) and SBP of 7.13 mm Hg ( based on moderate quality evidence ) compared to usual care . For both models , the evidence does not suggest a preferred setting of care delivery ( i.e. , primary care vs. hospital outpatient clinic vs. community clinic ) .

In : The Cochrane Library , Issue 2 , 2001 . Oxford : Up date Software . A substantive amendment to this systematic review was last made on 29 June 2000 . Cochrane review s are regularly checked and up date d if necessary . BACKGROUND Diabetes is a common chronic disease that is increasingly managed in primary care . Different systems have been proposed to manage diabetes care . OBJECTIVES To assess the effects of different interventions , targeted at health professionals or the structure in which they deliver care , on the management of patients with diabetes in primary care , outpatient and community setting s. SEARCH STRATEGY We search ed the Cochrane Effective Practice and Organisation of Care Group specialised register , the Cochrane Controlled Trials Register ( Issue 4 1999 ) , MEDLINE ( 1966 - 1999 ) , EMBASE ( 1980 - 1999 ) , Cinahl ( 1982 - 1999 ) , and reference lists of articles . SELECTION CRITERIA R and omised trials ( RCTs ) , controlled clinical trials ( CCTs ) , controlled before and after studies ( CBAs ) and interrupted time series ( ITS ) analyses of professional , financial and organisational strategies aim ed at improving care for people with Type 1 or Type 2 diabetes . The participants were health care professionals , including physicians , nurses and pharmacists . The outcomes included objective ly measured health professional performance or patient outcomes , and self-report measures with known validity and reliability . DATA COLLECTION AND ANALYSIS Two review ers independently extracted data and assessed study quality . MAIN RESULTS Forty-one studies were included involving more than 200 practice s and 48,000 patients . Twenty-seven studies were RCTs , 12 were CBAs , and two were ITS . The studies were heterogeneous in terms of interventions , participants , setting s and outcomes . The method ological quality of the studies was often poor . In all studies the intervention strategy was multifaceted . In 12 studies the interventions were targeted at health professionals , in nine they were targeted at the organization of care , and 20 studies targeted both . In 15 studies patient education was added to the professional and organisational interventions . A combination of professional interventions improved process outcomes . The effect on patient outcomes remained less clear as these were rarely assessed . Arrangements for follow-up ( organisational intervention ) also showed a favourable effect on process outcomes . Multiple interventions in which patient education was added or in which the role of the nurse was enhanced also reported favourable effects on patients ' health outcomes . REVIEW ERS ' CONCLUSION : Multifaceted professional interventions can enhance the performance of health professionals in managing patients with diabetes .  Organisational interventions that improve regular prompted recall and review of patients  ( central computerised tracking systems or nurses who regularly contact the patient ) can also improve diabetes management . The addition of patient-oriented interventions can lead to improved patient health outcomes . Nurses can play an important role in patient-oriented interventions , through patient education or facilitating adherence to treatment ABSTRACT Background : Cardiovascular diseases and diabetes are among the leading causes of premature adult deaths in India . Innovative approaches such as clinical decision support ( CDS ) software could play a major role in improving the quality of hypertension/diabetes care in primary care setting s. Objective : To describe the steps and processes in the development of mWellcare , a complex intervention based on mobile health ( mHealth ) technology . Methods : The Medical Research Council framework was used to develop mWellcare in four steps : ( 1 ) identify gaps in usual care through literature review and health facility assessment s ; ( 2 ) identify the components of the intervention through discussion s and consultations with experts ; ( 3 ) develop intervention ( clinical algorithms and mHealth system ) ; and ( 4 ) evaluate acceptability and feasibility through pilot testing in five community health centers . Results : Lack of evidence -based , integrated , and systematic management of chronic conditions were major gaps identified . Experts in information technology , clinical fields , and public health professionals identified intervention components to address these gaps . Thereafter , clinical algorithm context ualized to primary care setting s were prepared and the mWellcare intervention was developed . During the 2-month pilot , 631 patients diagnosed with hypertension and /or diabetes were registered , with a follow-up rate of 36.2 % . The major barrier was resistance to follow mWellcare recommended patient workflow , and to overcome it , we emphasized onsite training and orientation program to cover all health care team member in each CHC . Conclusion : A pilot-tested mWellcare intervention is an mHealth system with important components , i.e. integrated management of chronic conditions , evidence -based CDS , longitudinal health data and automated short-messaging service to reinforce compliance to drug intake and follow-up visit , which will be used by nurses at primary health care setting s in India . The effectiveness and cost-effectiveness of the intervention will be tested through a cluster r and omized trial ( trial registration number NCT02480062 ) Synthesizing evidence from r and omized controlled trials of  digital health education  poses some challenges . These include a lack of clear categorization of digital health education in the literature ; constantly evolving concepts , pedagogies , or theories ; and a multitude of methods , features , technologies , or delivery setting s. The Digital Health Education Collaboration was established to evaluate the evidence on digital education in health professions ; inform policymakers , educators , and students ; and ultimately , change the way in which these professionals learn and are taught . The aim of this paper is to present the overarching methodology that we use to synthesize evidence across our digital health education review s and to discuss challenges related to the process . For our research , we followed Cochrane recommendations for the conduct of systematic review s ; all review s are reported according to the PRISMA ( Preferred Reporting Items for Systematic Review s and Meta-Analyses ) guidance . This included assembling experts in various digital health education fields ; identifying gaps in the evidence base ; formulating focused research questions , aims , and outcome measures ; choosing appropriate search terms and data bases ; defining inclusion and exclusion criteria ; running the search es jointly with librarians and information specialists ; managing abstract s ; retrieving full-text versions of papers ; extracting and storing large data sets , critically appraising the quality of studies ; analyzing data ; discussing findings ; drawing meaningful conclusions ; and drafting research papers . The approach used for synthesizing evidence from digital health education trials is commonly regarded as the most rigorous benchmark for conducting systematic review s. Although we acknowledge the presence of certain biases ingrained in the process , we have clearly highlighted and minimized those biases by strictly adhering to scientific rigor , method ological integrity , and st and ard operating procedures . This paper will be a valuable asset for research ers and method ologists undertaking systematic review s in digital health education Background Depression is a common comorbidity in individuals with cognitive impairment . Those with cognitive impairments face unique challenges in receiving the benefits of many conventional therapies for depression , and may have poorer outcomes in areas such as recovery and quality of life . However , the stigmatization of mental health disorders , cost barriers and physical disabilities may prevent these individuals from seeking mental health care . An online , self-help intervention specifically developed for adults with cognitive deficits and depression may be particularly beneficial to this population . We aim to inform the design of such an intervention through a systematic review by answering the following research question : among adults with cognitive impairment ( including those with acquired brain injuries or neurodegenerative diseases ) , which technology-amenable interventions have been shown to effectively decrease symptoms of depression ? Specifically , psychotherapeutic and /or behavioural interventions that could be delivered in a self-guided , online system will be included . Methods Comprehensive electronic search es will be conducted in MEDLINE , EMBASE , PsycINFO and CINAHL . Additional studies will be obtained through manually search ing the references of relevant systematic review s , contacting primary authors of select articles and tracking conference proceedings and trial registries . Article titles and abstract s will be screened using predefined eligibility criteria , and then judged for their amenability to the proposed self-help , technology-based intervention . The full text of those articles with selected interventions will then be screened to determine final eligibility for inclusion . Included articles will be categorized by intervention type and assessed for risk of bias using the Cochrane Effective Practice and Organization of Care Risk of Bias tool for non-r and omized trials , controlled before-after studies and interrupted time series . The primary outcome will be a change in score on a vali date d depression scale , and adverse events will be documented as a secondary outcome . After data extraction from selected articles , pooling of data and meta- analysis will be conducted if a sufficient pool of studies with comparable methodology and quality are identified . Alternatively , plain language summaries will be developed . The quality of evidence will be assessed using the Grading of Recommendations Assessment , Development and Evaluation ( GRADE ) system . Systematic review registration PROSPERO Background A systematic review , with or without a meta- analysis , should be undertaken to determine if the research question of interest has already been answered before a new trial begins . There has been limited research on how systematic review s are used within the design of new trials , the aims of this study were to investigate how systematic review s of earlier trials are used in the planning and design of new r and omised trials . Methods Documentation from the application process for all r and omised trials funded by the National Institute for Health Research Health Technology Assessment ( NIHR HTA ) between 2006 and 2008 were obtained . This included the : commissioning brief ( if appropriate ) , outline application , minutes of the Board meeting in which the outline application was discussed , full application , detailed project description , referee comments , investigator response to referee comments , Board minutes on the full application and the trial protocol . Data were extracted on references to systematic review s and how any such review s had been used in the planning and design of the trial . Results 50 r and omised trials were funded by NIHR HTA during this period and documentation was available for 48 of these . The cohort was predominately individually r and omised parallel trials aim ing to detect superiority between two treatments for a single primary outcome . 37 trials ( 77.1 % ) referenced a systematic review within the application and 20 of these ( i.e. 41.7 % of the total ) used information contained in the systematic review in the design or planning of the new trial . The main areas in which systematic review s were used were in the selection or definition of an outcome to be measured in the trial ( 7 of 37 , 18.9 % ) , the sample size calculation ( 7 , 18.9 % ) , the duration of follow up ( 8 , 21.6 % ) and the approach to describing adverse events ( 9 , 24.3 % ) . Boards did not comment on the presence/absence or use of systematic review s in any application . Conclusions Systematic review s were referenced in most funded applications but just over half of these used the review to inform the design . There is an expectation from funders that applicants will use a systematic review to justify the need for a new trial but no expectation regarding further use of a systematic review to aid planning and design of the trial . Guidelines for applicants and funders should be developed to promote the use of systematic review s in the design and planning of r and omised trials , to optimise delivery of new studies informed by the most up-to- date evidence base and to minimise waste in research PURPOSE To revise the 2003 version of the American Urological Association 's ( AUA ) Guideline on the management of benign prostatic hyperplasia ( BPH ) . MATERIAL S AND METHODS From MEDLINE ® search es of English language publications ( January 1999 through February 2008 ) using relevant MeSH terms , articles concerning the management of the index patient , a male ≥45 years of age who is consulting a healthcare provider for lower urinary tract symptoms ( LUTS ) were identified . Qualitative analysis of the evidence was performed . Selected studies were stratified by design , comparator , follow-up interval , and intensity of intervention , and meta-analyses ( quantitative synthesis ) of outcomes of r and omized controlled trials were planned . Guideline statements were drafted by an appointed expert Panel based on the evidence . RESULTS The studies varied as to patient selection ; r and omization ; blinding mechanism ; run-in periods ; patient demographics , comorbidities , prostate characteristics and symptoms ; drug doses ; other intervention characteristics ; comparators ; rigor and intervals of follow-up ; trial duration and timing ; suspected lack of applicability to current US practice ; and techniques of outcomes measurement . These variations affected the quality of the evidence review ed making formal meta- analysis impractical or futile . Instead , the Panel and extractors review ed the data in a systematic fashion and without statistical rigor . Diagnosis and treatment algorithms were adopted from the 2005 International Consultation of Urologic Diseases . Guideline statements concerning pharmacotherapies , watchful waiting , surgical options and minimally invasive procedures were either up date d or newly drafted , peer review ed and approved by AUA Board of Directors . CONCLUSIONS New pharmacotherapies and technologies have emerged which have impacted treatment algorithms . The management of LUTS/BPH continues to evolve OBJECTIVES The objective of this review was to assess the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community . INCLUSION CRITERIA Types of participants Adult caregivers who provide support for people with dementia living in the community ( non-institutional care).Types of interventions Interventions design ed to support caregivers in their role such as skills training , education to assist in caring for a person living with dementia and support groups/programs . Interventions of formal approaches to care design ed to support caregivers in their role , care planning , case management and specially design ated members of the healthcare team - for example dementia nurse specialist or volunteers trained in caring for someone with dementia . Types of studies This review considered any meta-analyses , systematic review s , r and omised control trials , quasi-experimental studies , cohort studies , case control studies and observational studies without control groups that addressed the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community . SEARCH STRATEGY The search sought to identify published studies from 2000 to 2005 through the use of electronic data bases . Only studies in English were considered for inclusion . The initial search was conducted of the data bases , CINAHL , MEDLINE and PsychINFO using search strategies adapted from the Cochrane Dementia and Cognitive Improvement Group . A second more extensive search was then conducted using the appropriate Medical Subject Headings ( MeSH ) and keywords for other available data bases . Finally , h and search ing of reference lists of articles retrieved and of core dementia , geriatric and psycho geriatric journals was undertaken . ASSESSMENT OF QUALITY Method ological quality of each of the articles was assessed by two independent review ers using appraisal checklist developed by the Joanna Briggs Institute and based on the work of the Cochrane Collaboration and Centre for Review s and Dissemination . DATA COLLECTION AND ANALYSIS St and ardised mean differences or weighted mean differences and their 95 % confidence intervals were calculated for each included study reported in the meta- analysis . Results from comparable groups of studies were pooled in statistical meta- analysis using Review Manager Software from the Cochrane Collaboration . Heterogeneity between combined studies was tested using st and ard chi-square test . Where statistical pooling was not appropriate or possible , the findings are summarised in narrative form . RESULTS A comprehensive search of relevant data bases , h and search ing and cross referencing found 685 articles that were assessed for relevance to the review . Eighty-five papers appeared to meet the inclusion criteria based on title and abstract , and the full paper was retrieved . Of the 85 full papers review ed , 40 were accepted for inclusion , three were systematic review s , three were meta- analysis , and the remaining 34 were r and omised controlled trials . For the r and omised controlled trials that were able to be included in a meta- analysis , st and ardised mean differences or weighted mean differences and their 95 % confidence intervals were calculated for each . Results from comparable groups of studies were pooled in statistical meta- analysis using Review Manager Software and heterogeneity between combined studies was assessed by using the chi-square test . Where statistical pooling was not appropriate or possible , the findings are summarised in narrative form . The results are discussed in two main sections . Firstly it was possible to assess the effectiveness of different types of caregiver interventions on the outcome categories of depression , health , subjective well-being , self-efficacy and burden . Secondly , results are reported by main outcome category . For each of these sections , meta- analysis was conducted where it was possible ; otherwise , a narrative summary describes the findings . EFFECTIVENESS OF INTERVENTION TYPE Four categories of intervention were included in the review - psycho-educational , support , multi-component and other . Psycho-educational Thirteen studies used  psycho-educational interventions  , and all but one showed positive results across a range of outcomes . Eight studies were entered in a meta- analysis . No significant impact of psycho-educational interventions was found for the outcome categories of subjective well-being , self-efficacy or health . However , small but significant results were found for the categories of depression and burden . Support Seven studies discussed support only interventions and two of these showed significant results . These two studies were suitable for meta- analysis and demonstrated a small but significant improvement on caregiver burden . Multi-component Twelve of the studies report multi-component interventions and 10 of these report significant outcomes across a broad range of outcome measures including self-efficacy , depression , subjective well-being and burden . Unfortunately because of the heterogeneity of study design s and outcome measures , no meta- analysis was possible . Other interventions Other interventions included the use of exercise or nutrition which result ed in improvements in psychological distress and health benefits . Case management and a computer aided support intervention provided mixed results . One cognitive behavioural therapy study reported a reduction in anxiety and positive impacts on patient behaviour . EFFECTIVENESS OF INTERVENTIONS USING SPECIFIC OUTCOME CATEGORIES In addition to analysis by type of intervention it was possible to analyse results based on some outcome categories that were used across the studies . In particular the impact of interventions on caregiver depression was available for meta- analysis from eight studies . This indicated that multi-component and psycho-educational interventions showed a small but significant positive effect on caregiver depression . Five studies using the outcome category of caregiver burden  were entered into a meta- analysis and findings indicated that there were no significant effects of any of interventions . No meta- analysis was possible for the outcome categories of health , self-efficacy or subjective well-being . IMPLICATION S FOR PRACTICE From this review there is evidence to support the use of well- design ed psycho-educational or multi-component interventions for caregivers of people with dementia who live in the community . Factors that appear to positively contribute to effective interventions are those which : Factors which do not appear to have benefit in interventions are those which Introduction Unscheduled hospital admissions are an increasing burden on health systems worldwide . To date , initiatives to reduce admissions have had limited success as it is unclear which strategies effectively reduce admissions and are supported by a strong evidence -base . Therefore , we will conduct an overview to find , assess and summarise all published peer- review ed systematic review s of r and omised controlled trials that examine the effect of an intervention on  unplanned admissions among adults . Methods and analysis This is a protocol for a systematic overview of review s. We will search four data bases : Ovid MEDLINE , PubMed , Cochrane Data base of Systematic Review s and the Cochrane Data base of Abstract s of Review s of Effects . We will consider systematic review s and meta-analyses of r and omised controlled trials in adults ( ≥16 years old ) evaluating the effect of any intervention on unscheduled hospital admissions including those to treat , monitor , diagnose or prevent a health problem . We will only include review s that identified unscheduled hospitalisations as a prespecified outcome . Two authors will independently screen articles for inclusion using a priori criteria . We will assess the quality of included review s and extract ratings of the quality of evidence from within each review . We will create a hierarchical list of interventions based on estimates of absolute admission reductions and the quality of the evidence . Presentation of results will align with guidelines in the Cochrane H and book of Systematic Review s of Interventions and the Preferred Reporting Items for Systematic Review s and Meta- Analysis statement . Ethics and dissemination Ethics approval is not required . We will su bmi t the results of this study for peer- review publication . The results will inform future research and could be used by healthcare managers , administrators and policymakers to guide re source allocation decisions and inform local implementation and optimisation of interventions to reduce unscheduled hospital admissions OBJECTIVES To propose methods for mixed treatment comparisons ( MTC ) based on pooled summaries of the type produced in overviews of review s. STUDY DESIGN AND SETTING Overviews of review s ( umbrella review s ) summarize the results of multiple systematic review s into a single document . They report the summary estimates from the original pairwise meta-analyses and discuss them in narrative form , with the intention of identifying the most effective treatment . We present methods for MTC synthesis , tailored for use with overviews of review s. These generate a single internally consistent summary of all the relative treatment effects and assessment s of whether the summary is consistent with the data . These methods are applied to a published overview of treatments for childhood nocturnal enuresis . We apply the methods to both fixed-effect ( FE ) and r and om-effects ( RE ) meta-analyses of the original trials . RESULTS The summary relative risks based on FE meta-analyses , as originally published , were highly inconsistent . Those based on RE meta-analyses were consistent and could , given st and ard assumptions on comparability of treatment effects in meta- analysis , form a basis for coherent decision making . CONCLUSION Along with the summaries from systematic review s , MTC methods should be used in overviews to provide a single coherent analysis of all treatment comparisons and to check for evidence consistency 2011 ; 14 : 371–380 . 6 .

The focused PICO question was “ in case of pulp exposure in vital primary molars , how does MTA pulpotomy compare to CH in terms of clinical /radiographic success ? ” Methods and Material s : We retrieved published r and omized clinical trials ( RCTs ) of at least 6-month duration ; our search included articles published up to March 2013 in five following data bases : PubMed ( Medline ) , Cochrane data base of systematic review s , Science Citation Index , EMBASE , and Google Scholar . Mantel Haenszel and Inverse Variance-weighted methods were applied by STATA ; the relative risk ( RR ) was calculated with 95 % confidence intervals ( CI ) . Results : A total of 282 English articles were collected . Two authors independently screened the articles and five RCTs were selected ; data extraction and quality assessment were then carried out . Four RCTs were appropriate for meta- analysis according to their follow-up times by Mantel Haenszel method . Statistically significant difference was found between success rate of MTA compared to CH , with RR=0.08 ( 95 % CI , 0.02 - 0.39 ) , RR=0.19 ( 95 % CI , 0.08 - 0.46 ) , and RR=0.38 ( 95 % CI , 0.21 - 0.68 ) for 6- , 12- , and 24-month follow-ups , respectively . A significant difference was also observed for all included RCTs after analyses using the Inverse Variance-weighted method ( RR=0.44 ; 95 % CI , 0.27 - 0.72 ) . Conclusions : Systematic review /meta- analysis of included RCTs revealed that for pulpotomy of vital primary molars , MTA has better treatment outcomes compared to CH Objectives The objective of this review was to assess the effectiveness of interventions that assist caregivers to provide support for people living with dementia in the community .

Implication s for practice From this review there is evidence to support the use of well‐ design ed psycho‐educational or multi‐component interventions for caregivers of people with dementia who live in the community . Factors that appear to positively contribute to effective interventions are those which : Provide opportunities within the intervention for the person with dementia as well as the caregiver to be involved Encourage active participation in educational interventions for caregivers Offer individualised programs rather than group sessions Provide information on an ongoing basis , with specific information about services and coaching regarding their new role Target the care recipient particularly by reduction in behaviours Factors which do not appear to have benefit in interventions are those which : Simply refer caregivers to support groups Only provide self help material s Only offer peer UNLABELLED In June 2008 , the Medical Advisory Secretariat began work on the Diabetes Strategy Evidence Project , an evidence -based review of the literature surrounding strategies for successful management and treatment of diabetes . This project came about when the Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the Ministry 's newly released Diabetes Strategy .After an initial review of the strategy and consultation with experts , the secretariat identified five key areas in which evidence was needed . Evidence -based analyses have been prepared for each of these five areas : insulin pumps , behavioural interventions , bariatric surgery , home telemonitoring , and community based care . For each area , an economic analysis was completed where appropriate and is described in a separate report .

BACKGROUND Diabetes is a serious chronic condition affecting millions of people worldwide and is the sixth leading cause of death in Canada . In 2005 , an estimated 8.8 % of Ontario 's population had diabetes , representing more than 816,000 Ontarians . The direct health care cost of diabetes was $ 1.76 billion in the year 2000 and is projected to rise to a total cost of $ 3.14 billion by 2016 . Much of this cost arises from the serious long-term complications associated with the disease including : coronary heart disease , stroke , adult blindness , limb amputations and kidney disease . Type 2 diabetes accounts for 90 - 95 % of diabetes and while type 2 diabetes is more prevalent in people aged 40 years and older , prevalence in younger population s is increasing due to a rise in obesity and physical inactivity in children . Data from the United Kingdom Prospect i ve Diabetes Study ( UKPDS ) has shown that tight glycemic control can significantly reduce the risk of developing serious complications in type 2 diabetics . Despite physicians ' and patients ' knowledge of the importance of glycemic control , Canadian data has shown that only 38 % of patients with diabetes have HbA1C levels in the optimal range of 7 % or less . This statistic highlights the complexities involved in the management of diabetes , which is characterized by extensive patient involvement in addition to the support provided by physicians . An enormous dem and is , therefore , placed on patients to self-manage the physical , emotional and psychological aspects of living with a chronic illness . Despite differences in individual needs to cope with diabetes , there is general agreement for the necessity of supportive programs for patient self-management . While traditional programs were didactic models with the goal of improving patients ' knowledge of their disease , current models focus on behavioural approaches aim ed at providing patients with the skills and strategies required to promote and change their behaviour . Several meta-analyses and systematic review s have demonstrated improved health outcomes with  self-management support programs in type 2 diabetics . They have all , however , either looked at a specific component of self-management support programs ( i.e. self-management education ) or have been conducted in specific population s. Most review s are also qualitative and do not clearly define the interventions of interest , making findings difficult to interpret . Moreover , heterogeneity in the interventions has led to conflicting evidence on the components of effective programs . There is thus much uncertainty regarding the optimal design and delivery of these programs by policymakers . EVIDENCE -BASED ANALYSIS OF EFFECTIVENESS : RESEARCH QUESTIONS Are behavioural interventions  effective in improving glycemic control in adults with type 2 diabetes?Is the effectiveness of the intervention impacted by intervention characteristics ( e.g. delivery of intervention , length of intervention , mode of instruction , interventionist etc . ) ? INCLUSION CRITERIA English Language Published between January 1996 to August 2008 Type 2 diabetic adult population ( > 18 years)R and omized controlled trials ( RCTs ) Systematic review s , or meta-analyses Describing a multi-faceted self-management support intervention as defined by the 2007 Self-Management Mapping Guide (1)Reporting outcomes of glycemic control ( HbA1c ) with extractable data Studies with a minimum of 6-month follow up EXCLUSION CRITERIA Studies with a control group other than usual care Studies with a sample size < 30 Studies without a clearly defined intervention OUTCOMES OF INTEREST PRIMARY OUTCOME glycemic control ( HbA1c ) SECONDARY OUTCOMES systolic blood pressure ( SBP ) control , lipid control , change in smoking status , weight change , quality of life , knowledge , self-efficacy , managing psychosocial aspects of diabetes , assessing dissatisfaction and readiness to change , and setting and achieving diabetes goals . SEARCH STRATEGY A search was performed in OVID MEDLINE , MEDLINE In-Process and Other Non-Indexed Citations , EMBASE , the Cumulative Index to Nursing & Allied Health Literature ( CINAHL ) , The Cochrane Library , and the International Agency for Health Technology Assessment ( INAHTA ) for studies published between January 1996 and August 2008 . Abstract s were review ed by a single author and studies meeting the inclusion criteria outlined above were obtained . Data on population characteristics , glycemic control outcomes , and study design were extracted . Reference lists were also checked for relevant studies . The quality of the evidence was assessed as being either high , moderate , low , or very low according to the GRADE methodology . SUMMARY OF FINDINGS The search identified 638 citations published between 1996 and August 2008 , of which 12 met the inclusion criteria and one was a meta- analysis ( Gary et al. 2003 ) . The remaining 11 studies were RCTs ( 9 were used in the meta- analysis ) and only one was defined as small ( total sample size N=47 ) . SUMMARY OF PARTICIPANT DEMOGRAPHICS ACROSS STUDIES : A total of 2,549 participants were included in the 11 identified studies . The mean age of participants reported was approximately 58 years and the mean duration of diabetes was approximately 6 years . Most studies reported gender with a mean percentage of females of approximately 67 % . Of the eleven studies , two focused only on women and four included only Hispanic individuals . All studies evaluated type 2 diabetes patients exclusively . STUDY CHARACTERISTICS : The studies were conducted between 2002 and 2008 . Approximately six of 11 studies were carried out within the USA , with the remaining studies conducted in the UK , Sweden , and Israel ( sample size ranged from 47 to 824 participants ) . The quality of the studies ranged from moderate to low with four of the studies being of moderate quality and the remaining seven of low quality ( based on the Consort Checklist ) . Differences in quality were mainly due to method ological issues such as inadequate description of r and omization , sample size calculation allocation concealment , blinding and uncertainty of the use of intention-to-treat ( ITT ) analysis . Patients were recruited from several setting s : six studies from primary or general medical practice s , three studies from the community ( e.g. via advertisements ) , and two from outpatient diabetes clinics . A usual care control group was reported in nine of 11 of the studies and two studies reported some type of minimal diabetes care in addition to usual care for the control group . INTERVENTION CHARACTERISTICS : All of the interventions examined in the studies were mapped to the 2007 Self-management Mapping Guide . The interventions most often focused on problem solving , goal setting and encouraging participants to engage in activities that protect and promote health ( e.g. modifying behaviour , change in diet , and increase physical activity ) . All of the studies examined comprehensive interventions targeted at least two self-care topics ( e.g. diet , physical activity , blood glucose monitoring , foot care , etc . ) . Despite the homogeneity in the aims of the interventions , there was substantial clinical heterogeneity in other intervention characteristics such as duration , intensity , setting , mode of delivery ( group vs. individual ) , interventionist , and outcomes of interest ( discussed below ) . DURATION , INTENSITY AND MODE OF DELIVERY : Intervention duration s ranged from 2 days to 1 year , with many falling into the range of 6 to 10 weeks . The rest of the interventions fell into categories of ≤ 2 weeks ( 2 studies ) , 6 months ( 2 studies ) , or 1 year ( 3 studies ) . Intensity of the interventions varied widely from 6 hours over 2 days , to 52 hours over 1 year ; however , the majority consisted of interventions of 6 to 15 hours . Both individual and group sessions were used to deliver interventions . Group counselling was used in five studies as a mode of instruction , three studies used both individual and group sessions , and one study used individual sessions as its sole mode of instruction . ( ABSTRACT UNLABELLED In July 2009 , the Medical Advisory Secretariat ( MAS ) began work on Non-Invasive Cardiac Imaging Technologies for the Diagnosis of Coronary Artery Disease ( CAD ) , an evidence -based review of the literature surrounding different cardiac imaging modalities to ensure that appropriate technologies are accessed by patients suspected of having CAD . This project came about when the Health Services Branch at the Ministry of Health and Long-Term Care asked MAS to provide an evidentiary platform on effectiveness and cost-effectiveness of non-invasive cardiac imaging modalities . After an initial review of the strategy and consultation with experts , MAS identified five key non-invasive cardiac imaging technologies for the diagnosis of CAD . Evidence -based analyses have been prepared for each of these five imaging modalities : cardiac magnetic resonance imaging , single photon emission computed tomography , 64-slice computed tomographic angiography , stress echocardiography , and stress echocardiography with contrast . For each technology , an economic analysis was also completed ( where appropriate ) . A summary decision analytic model was then developed to encapsulate the data from each of these reports ( available on the OHTAC and MAS website).The Non-Invasive Cardiac Imaging Technologies for the Diagnosis of Coronary Artery Disease series is made up of the following reports , which can be publicly accessed at the MAS website at : www.health.gov.on.ca/mas or at www.health.gov.on.ca/english/providers/program/mas/mas_about.htmlSINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE : An Evidence -Based Analysis STRESS ECHOCARDIOGRAPHY FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE : An Evidence -Based Analysis STRESS ECHOCARDIOGRAPHY WITH CONTRAST FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE : An Evidence -Based Analysis 64-Slice Computed Tomographic Angiography for the Diagnosis of Coronary Artery Disease : An Evidence -Based Analysis CARDIAC MAGNETIC RESONANCE IMAGING FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE : An Evidence -Based Analysis Pease note that two related evidence -based analyses of non-invasive cardiac imaging technologies for the assessment of myocardial viability are also available on the MAS website : POSITRON EMISSION TOMOGRAPHY FOR THE ASSESSMENT OF MYOCARDIAL VIABILITY : An Evidence -Based Analysis MAGNETIC RESONANCE IMAGING FOR THE ASSESSMENT OF MYOCARDIAL VIABILITY : an Evidence -Based Analysis The Toronto Health Economics and Technology Assessment Collaborative has also produced an associated economic report entitled : The Relative Cost-effectiveness of Five Non-invasive Cardiac Imaging Technologies for Diagnosing Coronary Artery Disease in Ontario [ Internet ] . Available from : http://theta.utoronto.ca/reports/?id=7 OBJECTIVE The objective of the analysis is to determine the diagnostic accuracy of single photon emission tomography ( SPECT ) in the diagnosis of coronary artery disease ( CAD ) compared to the reference st and ard of coronary angiography ( CA ) . The analysis is primarily meant to allow for indirect comparisons between non-invasive strategies for the diagnosis of CAD , using CA as a reference st and ard . SPECT : Cardiac SPECT , or myocardial perfusion scintigraphy ( MPS ) , is a widely used nuclear , non-invasive image acquisition technique for investigating ischemic heart disease . SPECT is currently appropriate for all aspects of detecting and managing ischemic heart disease including diagnosis , risk assessment /stratification , assessment of myocardial viability , and the evaluation of left ventricular function . Myocardial perfusion scintigraphy was originally developed as a two-dimensional planar imaging technique , but SPECT acquisition has since become the clinical st and ard in current practice . Cardiac SPECT for the diagnosis of CAD uses an intravenously administered radiopharmaceutical tracer to evaluate regional coronary blood flow usually at rest and after stress . The radioactive tracers thallium ( 201Tl ) or technetium-99 m ( 99mTc ) , or both , may be used to visualize the SPECT acquisition . Exercise or a pharmacologic agent is used to achieve stress . After the administration of the tracer , its distribution within the myocardium ( which is dependent on myocardial blood flow ) is imaged using a gamma camera . In SPECT imaging , the gamma camera rotates around the patients for 10 to 20 minutes so that multiple two-dimensional projections are acquired from various angles . The raw data are then processed using computational algorithms to obtain three-dimensional tomographic images . Since its inception , SPECT has evolved and its techniques/applications have become increasingly more complex and numerous . Accordingly , new techniques such as attenuation correction and ECG gating have been developed to correct for attenuation due to motion or soft-tissue artifact and to improve overall image clarity . RESEARCH QUESTIONS What is the diagnostic accuracy of SPECT for the diagnosis of CAD compared to the reference st and ard of CA?Is  SPECT cost-effective compared to other non-invasive cardiac imaging modalities for the diagnosis of CAD?What are the major safety concerns with SPECT when used for the diagnosis of CAD ? METHODS A preliminary literature search was performed across OVID MEDLINE , MEDLINE In-Process and Other Non-Indexed Citations , EMBASE , the Cochrane Library , and the International Agency for Health Technology Assessment ( INAHTA ) for all systematic review s/meta- analysis published between January 1 , 2004 and August 22 , 2009 . A comprehensive systematic review was identified from this search and used as a basis for an up date d search . A second comprehensive literature search was then performed on October 30 , 2009 across the same data bases for studies published between January 1 , 2002 and October 30 , 2009 . Abstract s were review ed by a single review er and , for those studies meeting the eligibility criteria , full-text articles were obtained . Reference lists were also h and - search ed for any additional studies . Inclusion Criteria Exclusion Criteria Systematic review s , meta-analyses , controlled clinical trials , and observational studies Minimum sample size of 20 patients who completed coronary angiographyUse of CA as a reference st and ard for the diagnosis of CAD Data available to calculate true positives ( TP ) , false positives ( FP ) , false negatives ( FN ) and true negatives (TN)Accuracy data reported by patient not by segmentEnglish language Non- systematic review s , case reportsGrey literature and abstract sTrials using planar imaging onlyTrials conducted in patients with non-ischemic heart disease Studies done exclusively in special population s ( e.g. , patients with left branch bundle block , diabetics , minority population s ) unless insufficient data available SUMMARY OF FINDINGS Eighty-four observational studies , one non-r and omized , single arm controlled clinical trial , and one poorly reported trial that appeared to be a r and omized controlled trial ( RCT ) met the inclusion criteria for this review . All studies assessed the diagnostic accuracy of myocardial perfusion SPECT  for the diagnosis of CAD using CA as a reference st and ard . Based on the results of these studies the following conclusions were made : According to very low quality evidence , the addition of attenuation correction to traditional or ECG-gated SPECT greatly improves the specificity of SPECT  for the diagnosis of CAD although this improvement is not statistically significant . A trend towards improvement of specificity was also observed with the addition of ECG gating to traditional SPECT.According to very low quality evidence , neither the choice of stress agent ( exercise or pharmacologic ) nor the choice of radioactive tracer ( technetium vs. thallium ) significantly affect the diagnostic accuracy of SPECT  for the diagnosis of CAD although a trend towards accuracy improvement was observed with the use of pharmacologic stress over exercise stress and technetium over thallium . Considerably heterogeneity was observed both within and between trials . This heterogeneity may explain why some of the differences observed between accuracy estimates for various subgroups were not statistically significant . More complex analytic techniques such as meta-regression may help to better underst and which study characteristics significantly influence the diagnostic accuracy of SPECT
The narrative synthesis provided mixed effects of CHITs on other clinical , psychosocial , behavioral , and knowledge outcomes .
Conclusions The use of CHITs appears to be more effective than usual care in improving glycemic control for patients with diabetes .
However , their effectiveness did not remain consistent over time and in other patient outcomes .
Objective To reveal the effects of consumer-oriented health information technologies ( CHITs ) on patient outcomes in diabetes management over time through systematic review and meta- analysis .
