ObjectivesThe rate of admissions for ambulatory care sensitive conditions (ACSCs) is a key outcome indicator for primary care, and patient experience (PX) is a crucial process indicator. Studies have reported higher rates of admission for ACSCs in rural areas than in urban areas. Whether there is an association between admissions for ACSCs and PX in rural areas has not been examined. This study aimed to document admissions for ACSCs on Japanese rural islands, and assess whether there was an association between the rate of admissions for ACSCs and PX.DesignMulticentred, prospective, cohort studySettingThis study was conducted on five rural islands in Okinawa, Japan.ParticipantsThe study participants were all island inhabitants aged 65 years or older.Primary outcome measuresThis study examined the association between ACSCs and PX assessed by a questionnaire, the Japanese Version of Primary Care Assessment Tool. ACSCs were classified using the International Classification of Diseases, Tenth Revision, and the rate of admissions for ACSCs in 1 year.ResultsOf 1258 residents, 740 completed the questionnaire. This study documented 38 admissions for ACSCs (29 patients, males/females: 15/14, median age 81.9) that included congestive heart failure (11), pneumonia (7) and influenza (5). After adjusting for covariates and geographical clustering, admissions for ACSCs had a significant positive association with each patient’s PX scores (OR per 1 SD increase=1.62, 95% CI 1.02–2.61).ConclusionsPhysicians serving rural areas need to stress the importance of preventive interventions for heart failure, pneumonia and influenza to reduce the number of admissions for ACSCs. Contrary to previous studies, our findings might be explained by close patient–doctor relationships on the rural islands.

IntroductionDespite significant progress in the last few decades, infectious diseases remain a significant threat to children’s health in low-income and middle-income countries. Effective means of prevention and control for these diseases exist, making any differences in the burden of these diseases between population groups or countries inequitable. Yet, gaps remain in our knowledge of the effect these public health interventions have on health inequalities in children, especially in low-income and middle-income countries. This umbrella review aims to address some of these gaps by exploring which public health interventions are effective in reducing morbidity, mortality and health inequalities from infectious diseases among children in low-income and middle-income countries.Methods and analysisAn umbrella review will be conducted to identify systematic reviews or evidence synthesis of public health interventions that reduce morbidity, mortality and/or health inequalities due to infectious diseases among children (aged under 5 years) in low-income and middle-income countries. The interventions of interest are public health interventions targeting infectious diseases or associated risk factors in children. We will search for reviews reporting health and health inequalities outcomes in and between populations. The literature search will be undertaken using the Cochrane Library, Medline, EMBASE, the CAB Global Health database, Health Evidence, the Campbell Collaboration Library of Systematic Reviews, International Initiative for Impact Evaluation Systematic review repository, Scopus, the Social Sciences Citation Index and PROSPERO. Additionally, a manual search will be performed in Google Scholar and three international organisations websites (UNICEF Office of Research—Innocenti, UNICEF, WHO) to capture grey literature. Data from the records meeting our inclusion/exclusion criteria will be collated using a narrative synthesis approach.Ethics and disseminationThis review will exclusively work with anonymous group-level information available from published reviews. No ethical approval was required.The results of the review will be submitted for publication in academic journals and presented at international public health conferences. Additionally, key findings will be summarised for dissemination to a wider policy and general public audience as part of the Centre for Global Health Inequalities Research’s policy work.PROSPERO registration numberCRD42019141673

ObjectiveTo determine if continuous subcutaneous insulin infusion (CSII) therapy is associated with lower glycated
haemoglobin (HbA1c) variability (long-term glycaemic variability; GV) relative to multiple daily injection (MDI) treatment in adults with type 1 diabetes mellitus (T1DM).DesignRetrospective audit.Setting and participantsClinic records from 506 adults with T1DM from two tertiary Australian hospitals.Outcome measuresLong-term GV was assessed by HbA1c SD and coefficient of variation (CV) in adults on established MDI or CSII therapy, and in a subset changing from MDI to CSII.ResultsAdults (n=506, (164 CSII), 50% women, mean±SD age 38.0±15.3 years, 17.0±13.7 years diabetes, mean HbA1c 7.8%±1.2% (62±13 mmol/mol) on CSII, 8.0%±1.5% (64±16 mmol/mol) on MDI) were followed for 4.1±3.6 years. CSII use was associated with lower GV (HbA1c SD: CSII vs MDI 0.5%±0.41% (6±6 mmol/mol) vs 0.7%±0.7% (9±8 mmol/mol)) and CV: CSII vs MDI 6.7%±4.6% (10±10 mmol/mol) vs 9.3%±7.3% (14±13 mmol/mol), both p<0.001. Fifty-six adults (73% female, age 36±13 years, 16±13 years diabetes, HbA1c 7.8%±0.8% (62±9 mmol/mol)) transitioned from MDI to CSII. Mean HbA1c fell by 0.4%. GV from 1 year post-CSII commencement decreased significantly, HbA1c SD pre-CSII versus post-CSII 0.7%±0.5% (8±5 mmol/mol) vs 0.4%±0.4% (5±4 mmol/mol); p<0.001, and HbA1c CV 9.2%±5.5% (13±8 mmol/mol) vs 6.1%±3.9% (9±5 mmol/mol); p<0.001.ConclusionsIn clinical practice with T1DM adults relative to MDI, CSII therapy is associated with lower HbA1c GV.

ObjectivesThis study aimed to assess the coverage and explore enablers and challenges in implementation of direct benefit transfer (DBT) cash incentive scheme for patients with tuberculosis (TB).DesignThis is a mixed methods study comprising a quantitative cohort and descriptive qualitative study.SettingThe study was conducted in City TB Centre, Vadodara, Western India.ParticipantsWe used routinely collected data under the National TB Programme (NTP) on patients with TB notified between April and September 2018 and initiated on first-line anti-tuberculosis treatment (ATT) to assess the coverage of DBT. We interviewed NTP staff and patients to understand their perceptions.Primary and secondary outcome measuresThe study outcomes are receipt of DBT (primary), time to receipt of first instalment of DBT and treatment outcome.ResultsAmong 1826 patients, 771 (42.2%) had received at least one instalment. Significantly more patients from the public sector had received DBT (at least one instalment) compared with those from private sector (adjusted relative risk (adjRR)=16.3; 95% CI 11.6 to 23.0). Among public sector patients, 7.3% (49/671) had received first instalment within 2 months of treatment initiation. Median (IQR) time to receipt of first instalment was 5.2 (3.4, 7.4) months. Treatment in private sector, residing outside city limits and being HIV non-reactive were significantly (p<0.001) associated with longer time to receipt. Timely and sufficient fund release, adequate manpower and adequate logistics in TB centre were the enablers. Inability of patients to open bank accounts due to lack of identity/residence proof, their reluctance to share personal information and inadequate support from private providers were the challenges identified in implementation.ConclusionDuring the early phase of DBT implementation, the coverage was low and there were delays in benefit transfer. Facilitating opening of bank accounts for patients by NTP staff and better support from private providers may improve DBT coverage. Repeat assessment of DBT coverage after streamlining of implementation is recommended.

ObjectivesThere are more than 6000 heterogeneous rare diseases and little is known about shared experiences of affected individuals in everyday life and healthcare. Objective of this study was to explore perceived burden of patients with rare chronic diseases and identify commonalities and differences in the experiences of patients with four heterogeneous conditions.DesignA qualitative focus group study.SettingIn four separate and diagnostically homogeneous focus groups, we asked patients about the perceived burden of living with their rare disease. The focus groups took place at a university medical centre in Germany.ParticipantsIndividuals with neurofibromatosis type 1 (n=4), primary sclerosing cholangitis (n=5), pulmonary arterial hypertension (n=4) and Marfan syndrome (n=5).ResultsWe identified five main themes: medical problems, psychological burden, problems with the healthcare system, constraints and interpersonal problems. While medical problems differed widely between the diagnostic groups, patients with different conditions independently reported many common problems including psychological burden, constraints in professional, personal and daily life, stigmatisation and others lacking understanding. Shared problems pertaining to the healthcare system seem related to the rarity of the conditions (eg, limited access to adequate care, lack of knowledge).ConclusionsDespite clinical heterogeneity of rare diseases, affected individuals have many common experiences. Some of these experiences may resemble the burden of living with a chronic disease. However, patients reported aspects, which seem to be specific for rare chronic diseases. Generic interventions targeting shared burdens among patients with different diseases could provide adequate treatment in light of finite healthcare resources.
Understanding the factors that influence the quality of paid disability support for adults with acquired neurological disability and complex needs: a scoping review protocol
Authors: Topping Megan , Douglas Jacinta , Winkler Di 
Published: December 2019

IntroductionAdults with disability as the result of an acquired neurological disorder often have varying and complex support needs. Consequently, adults with complex needs often require paid support to enable them to exercise choice and control and participate fully and effectively in society. Given support is so critical for this population, this scoping review aims to further understand the factors that influence the quality of paid disability support for adults with acquired neurological disability and complex needs.Methods and analysisThe methodology proposed by Arksey and O’Malley, with the modifications recommended by Levac and O’Brien and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis: extension for Scoping Reviews will be used. Systematic and comprehensive electronic database searches will be conducted in MEDLINE, CINAHL, PsycINFO, Scopus and Embase. The review will follow a six-stage framework including (1) identifying the research question/s, (2) identifying the relevant studies, with (3) study selection and (4) charting of data by two independent coders, (5) collating, summarising and reporting data and (6) expert consultation which will be sought from people with lived experience, as well as clinical and academic experts. Work on this scoping review began in June 2019 and will be completed by June 2020.Ethics and disseminationEthical approval will not be required to conduct the scoping review. However, the consultation with people with lived experience will be conducted via codesign workshops. The codesign workshops have received ethical approval from La Trobe University Ethics Committee (reference number: HEC19232). It is intended that review findings will be made available to relevant stakeholders through a peer-reviewed publication, conference presentations and workshops.

Published: December 2019

IntroductionWhy some people develop chronic pain following an acute episode of low back pain is unknown. Recent cross-sectional studies have suggested a relationship between aberrant sensorimotor cortex activity and pain persistence. The UPWaRD (Understanding persistent Pain Where it ResiDes) cohort study is the first prospective, longitudinal investigation of sensorimotor cortex activity in low back pain. This paper describes the development of a causal model and statistical analysis plan for investigating the causal effect of sensorimotor cortex activity on the development of chronic low back pain.Methods and analysisSensorimotor cortex activity was assessed within 6 weeks of low back pain onset using somatosensory evoked potentials and transcranial magnetic stimulation mapping techniques. Chronic low back pain is defined as ongoing pain (Numerical Rating score ≥1) or disability (Roland Morris Disability Questionnaire score ≥3) at 6 months follow-up. Variables that could confound the relationship between sensorimotor cortex activity and chronic low back pain were identified using a directed acyclic graph and content expertise was used to specify known causal paths. The statistical model was developed ‘a priori’ to control for confounding variables identified in the directed acyclic graph, allowing an unbiased estimate of the causal effect of sensorimotor activity in acute low back pain on the development of chronic pain. The statistical analysis plan was finalised prior to follow-up of all participants and initiation of analysis.Ethics and disseminationEthical approval has been obtained from Western Sydney University Human Research Ethics Committee (H10465) and from Neuroscience Research Australia (SSA: 16/002). Dissemination will occur through presentations at national and international conferences and publications in international peer-reviewed journals.Trial registration numberACTRN12619000002189 (retrospectively registered)
Average medical cost of fatal and non-fatal injuries by type in the USA
Authors: Peterson Cora , Xu Likang , Florence Curtis 
Published: December 2019

ObjectiveTo estimate the average medical care cost of fatal and non-fatal injuries in the USA comprehensively by injury type.MethodsThe attributable cost of injuries was estimated by mechanism (eg, fall), intent (eg, unintentional), body region (eg, head and neck) and nature of injury (eg, fracture) among patients injured from 1 October 2014 to 30 September 2015. The cost of fatal injuries was the multivariable regression-adjusted average among patients who died in hospital emergency departments (EDs) or inpatient settings as reported in the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample and National Inpatient Sample, controlling for demographic (eg, age), clinical (eg, comorbidities) and health insurance (eg, Medicaid) factors. The 1-year attributable cost of non-fatal injuries was assessed among patients with ED-treated injuries using MarketScan medical claims data. Multivariable regression models compared total medical payments (inpatient, outpatient, drugs) among non-fatal injury patients versus matched controls during the year following injury patients’ ED visit, controlling for demographic, clinical and insurance factors. All costs are 2015 US dollars.ResultsThe average medical cost of all fatal injuries was approximately $6880 and $41 570 per ED-based and hospital-based patient, respectively (range by injury type: $4764–$10 289 and $31 912–$95 295). The average attributable 1-year cost of all non-fatal injuries per person initially treated in an ED was approximately $6620 (range by injury type: $1698–$80 172).Conclusions and relevanceInjuries are costly and preventable. Accurate estimates of attributable medical care costs are important to monitor the economic burden of injuries and help to prioritise cost-effective public health prevention activities.

Myostatin (MSTN) is a transforming growth factor (TGF)-β superfamily member that acts as a negative regulator of muscle growth and may play a role in cardiac remodeling. We hypothesized that inhibition of activin type II receptors (ACTRII) to reduce MSTN signaling would reduce pathological cardiac remodeling in experimental heart failure (HF). C57BL/6J mice underwent left anterior descending coronary artery ligation under anesthesia to induce myocardial infarction (MI) or no ligation (sham). MI and sham animals were each randomly divided into groups ( n ≥ 10 mice/group) receiving an ACTRII or ACTRII/TGFβ receptor-signaling inhibiting strategy: 1) myo-Fc group (weekly 10 mg/kg Myo-Fc) or 2) Fol + TGFi group (daily 12 µg/kg follistatin plus 2 mg/kg TGFβ receptor inhibitor), versus controls. ACTRII/TGFBR signaling inhibition preserved cardiac function by echocardiography and prevented an increase in brain natriuretic peptide (BNP). ACTRII/TGFBR inhibition resulted in increased phosphorylation (P) of Akt and decreased P-p38 mitogen-activated protein kinase (MAPK) in MI mice. In vitro, Akt contributed to P-SMAD2,3, P-p38, and BNP regulation in cardiomyocytes. ACTRII/TGFBR inhibition increased sarco/endoplasmic reticulum Ca2+-ATPase (SERCA2a) levels and decreased unfolded protein response (UPR) markers in MI mice. ACTRII/TGFBR inhibition was associated with a decrease in cardiac fibrosis and fibrosis markers, connective tissue growth factor (CTGF), type I collagen, fibronectin, α-smooth muscle actin, and matrix metalloproteinase (MMP)-12 in MI mice. MSTN exerted a direct regulation on the UPR marker eukaryotic translation initiation factor-2α (eIf2α) in cardiomyocytes. Our study suggests that ACTRII ligand inhibition has beneficial effects on cardiac signaling and fibrosis after ischemic HF. NEW & NOTEWORTHY Activin type II receptor ligand inhibition resulted in preserved cardiac function, a decrease in cardiac fibrosis, improved SERCA2a levels, and a prevention of the unfolded protein response in mice with myocardial infarction.

Timing and indication for pulmonary valve replacement (PVR) in patients with repaired Tetralogy of Fallot (rToF) and pulmonary regurgitation (PR) are uncertain. To improve understanding of pumping mechanics, we investigated atrioventricular coupling before and after surgical PVR. Cardiovascular magnetic resonance was performed in patients ( n = 12) with rToF and PR > 35% before and after PVR and in healthy controls ( n = 15). Atrioventricular plane displacement (AVPD), global longitudinal peak systolic strain (GLS), atrial and ventricular volumes, and caval blood flows were analyzed. Right ventricular (RV) AVPD and RV free wall GLS were lower in patients before PVR compared with controls ( P < 0.0001; P < 0.01) and decreased after PVR ( P < 0.0001 for both). Left ventricular AVPD was lower in patients before PVR compared with controls ( P < 0.05) and decreased after PVR ( P < 0.01). Left ventricular GLS did not differ between patients and controls ( P > 0.05). Right atrial reservoir volume and RV stroke volume generated by AVPD correlated in controls ( r = 0.93; P < 0.0001) and patients before PVR ( r = 0.88; P < 0.001) but not after PVR. In conclusion, there is a clear atrioventricular coupling in patients before PVR that is lost after PVR, possibly because of loss of pericardial integrity. Impaired atrioventricular coupling complicates assessment of ventricular function after surgery using measurements of longitudinal function. Changes in atrioventricular coupling seen in patients with rToF may be energetically unfavorable, and long-term effects of surgery on atrioventricular coupling is therefore of interest. Also, AVPD and GLS cannot be used interchangeably to assess longitudinal function in rToF. NEW & NOTEWORTHY There is a clear atrioventricular coupling in patients with Tetralogy of Fallot (ToF) and pulmonary regurgitation before surgical pulmonary valve replacement (PVR) that is lost after operation, possibly because of loss of pericardial integrity. The impaired atrioventricular coupling complicates assessment of ventricular function after surgery when using measurements of longitudinal function. Left ventricular atrioventricular plane displacement (AVPD) found differences between patients and controls and changes after PVR that longitudinal strain could not detect. This indicates that AVPD and strain cannot be used interchangeably to assess longitudinal function in repaired ToF.
