ObjectivesPatients with hyperuricaemia are at relatively high risk of developing coronary heart disease (CHD). The purpose of this study was to examine the relationship between high-sensitivity C-reactive protein (hs-CRP) and CHD risk in a middle-aged and elderly population with hyperuricaemia.DesignA cross-sectional study.Setting and participantsThis study was conducted in a health examination centre of China. Participants were diagnosed with hyperuricaemia based on uric acid concentrations. Specifically, males with a uric acid concentration ≥416 μmol/L were included, as well as females with a concentration ≥360 μmol/L.Main outcome measures10-year CHD risk for each individual was evaluated using Framingham risk score based on the Adult Treatment Panel III charts.ResultsA total of 517 patients with hyperuricaemia (438 males and 79 females) aged from 40 to 85 years old were included in the present study. 193 (37.3%) patients were defined with relatively high 10-year CHD risk. Compared with the lowest quintile, the crude ORs of relatively high 10-year CHD risks were 1.43 (95% CI 0.78 to 2.63, p=0.245), 2.05 (95% CI 1.14 to 3.67, p=0.016), 2.77 (95% CI 1.54 to 4.98, p=0.001), 2.12 (95% CI 1.18 to 3.80, p=0.012) in the second, third, fourth and fifth quintiles of serum hs-CRP level, respectively (p for trend=0.057). The multivariable-adjusted ORs of relatively high 10-year CHD risk were 1.40 (95% CI 0.75 to 2.61, p=0.291) in the second, 2.05 (95% CI 1.13 to 3.72, p=0.019) in the third, 2.69 (95% CI 1.47 to 4.89, p=0.001) in the fourth and 2.10 (95% CI 1.15 to 3.84, p=0.016) in the fifth quintile of serum hs-CRP level when compared with the lowest quintile (p for trend=0.068).ConclusionThis study showed that ORs of relatively high 10-year CHD risk were raised in patients with hyperuricaemia with higher serum hs-CRP level; however, there was a not significant but borderline trend association and that more research is needed.

Published: October 2019

ObjectiveTo evaluate the ‘Shared Decision-making and Dialysis Choice’ (SDM-DC) intervention with regard to patients’ experience and involvement.DesignSemistructured individual interviews and systematic text condensation for data analysis.SettingThe SDM-DC intervention was implemented and evaluated at four different hospitals in Denmark.ParticipantsA total of 348 patients had received the SDM-DC intervention, and of these 29 patients were interviewed.InterventionsSDM-DC was designed for patients facing a choice of dialysis modality. The available modalities were haemodialysis and peritoneal dialysis, either performed by patients on their own or with help from a healthcare professional. The intervention was tailored to individual patients and consisted of three meetings with a dialysis coordinator who introduced a patient decision aid named ‘Dialysis Choice’ to the patient.FindingsThe following were the four main findings: the decision was experienced as being the patient’s own; the meetings contributed to the decision process; ‘Dialysis Choice’ contributed to the decision process; and the decision process was experienced as being iterative.ConclusionsThe patients experienced SDM-DC as involving them in their choice of dialysis modality. Due to the iterative properties of the decision-making process, a shared decision-making intervention for dialysis choice has to be adapted to the needs of individual patients. The active mechanisms of the meetings with the dialysis coordinator were (1) questions to and from the patient, and (2) the dialysis coordinator providing accurate information about the options. The overview of options and the value clarification tool in the decision aid were particularly helpful in establishing a decision-making process based on informed preferences.

IntroductionCentral venous catheterisation is a common procedure in intensive care therapy and the use of central venous catheters is essential for treatment of many medical disorders. Although rare, central venous catheterisation is associated with mechanical complications that can be life-threatening if untreated. Real-time ultrasound guidance reduces the incidence of mechanical complications when compared with the anatomic landmark method. The purpose of this study is to determine the incidence of and potential risk factors associated with early mechanical complications of central venous catheterisation in an era where real-time ultrasound guidance has become clinical practice.Methods and analysisThis is a prospective, controlled, multicentre, observational study. All participating hospitals follow the same clinical guidelines for central venous catheterisation. Each central venous catheter insertion will be recorded in the common electronic chart system according to a recently revised template. An automated script-based search will identify all recorded central venous catheter insertion templates during the study period and relevant variables will be extracted. Outcome measures and independent variables are pre-defined in this study protocol. Multivariable and univariable logistic regression analysis will be used to determine associations and risk factors of mechanical complications.Ethics and disseminationThe Regional Ethical Review Board in Lund, Sweden has approved this study. The results will be submitted for publication in peer-reviewed medical journals and presented at national and international scientific meetings.Trial registration numberNCT03782324.

ObjectivesGiven the changing understanding of overdiagnosis of screen detected cancers and advances in technology to detect and prevent cancer, updating and scaling back cancer screening programmes is becoming increasingly necessary. The National Cervical Screening Programme (NCSP) in Australia was recently deintensified, with the changes implemented in December 2017. This study examines women’s understanding and acceptance of the renewed screening protocol and how such changes can be communicated more effectively.DesignFocus groups structured around a presentation of information about the renewed NCSP, with discussions of the information facilitated throughout. Qualitative data analysis was conducted.SettingAustraliaParticipantsSix focus groups were conducted in November 2017 with a community sample of 49 women aged 18–74.ResultsWomen demonstrated little or no awareness of the upcoming screening changes in the period just before they occurred. Women expressed most concern and fear that the increased screening interval (from 2 to 5 years) and later age of first screening (from age 18 to 25 years) could lead to missing cancers. Concerns about exit testing were less common. Understanding of the natural history and the prevalence of both human papillomavirus and cervical cancer, and the nature of the new test (catching it ‘earlier’) was key to alleviate concerns about the increased screening interval.ConclusionsDeintensifying screening programmes should be accompanied by clear and coherent communication of the changes, including the rationale behind them, to limit concerns from the public and facilitate acceptance of renewed programmes. In this case, understanding the biology of cervical cancer was crucial.
Impact of local health insurance schemes on primary care management and control of hypertension: a cross-sectional study in Shenzhen, China

Published: October 2019

BackgroundIn China, the local health insurance coverage is usually related to timely reimbursement of hypertensive care in primary care settings, while health insurance that is not local could represent an obstacle for accessibility and affordability of primary care for hypertensive patients.ObjectiveTo investigate whether local health insurance schemes have a positive impact on hypertension management and control.DesignWe performed an on-site, face-to-face, patients survey in community health centres (CHCs) in Shenzhen, China.Setting and participantsHypertensive patients seeking healthcare from CHCs were selected as study participants using a systematic sampling design.Main measuresWe obtained information about insurance status, social capital, drug treatment and control of hypertension. Multivariable stepwise logistic regression models were constructed to test the associations between insurance status and hypertension management, as well as insurance status and social capital.ResultsA total of 867 participants were included in the final study analysis. We found that the participants covered by local insurance schemes were more likely to be managed in primary care facilities (61.1% vs 81.9%; OR=2.58, 95% CI: 1.56 to 4.28), taking antihypertensive drugs (77.2% vs 88.0%; OR=2.23, 95% CI: 1.37 to 3.62) and controlling blood pressure (43.0% vs 52.4%; OR=1.46, 95% CI: 1.03 to 2.07) when compared with those with insurance coverage that is not local. The participants covered by local insurance schemes reported a higher score of perceived generalised trust than those without (4.23 vs 3.97; OR=0.74, 95% CI: 0.53 to 0.86).ConclusionOur study demonstrates that local health insurance coverage could help improve management and control of hypertension in a primary care setting. Policymakers suggest initiating social interventions for better management and control of hypertension at the primary care level, although the causal pathways across insurance status, social capital and control of hypertension deserve further investigations.

ObjectiveTo determine discontinuation rates, patterns of use and predictors of discontinuation of non-vitamin K antagonist oral anticoagulants (NOACs) among patients with non-valvular atrial fibrillation (NVAF) in the first year of therapy.DesignPopulation-based cohort study.SettingUK primary care.Population11 481 patients with NVAF and a first prescription (index date) for apixaban, dabigatran or rivaroxaban (January 2012 to December 2016) with at least 1 year of follow-up and at least one further NOAC prescription in the year following the index date were identified. 1 year rates and patterns of discontinuation were described.Primary and secondary outcome measuresOutcome measures were the percentage of patients who, in the first year from starting NOAC therapy, discontinued with their oral anticoagulant (OAC) therapy (discontinuation was defined as a gap in OAC therapy of >30 days); switched OAC within 30 days; discontinued and reinitiated OAC therapy. Predictors of discontinuation were also evaluated.Results1 year discontinuation rates according to the index NOAC were 26.1% for apixaban, 40.0% for dabigatran and 29.6% for rivaroxaban. Reinitiation rates were 18.1% for apixaban, 21.7% for dabigatran and 17.3% for rivaroxaban, and switching rates were 2.8% for apixaban, 8.8% for dabigatran and 4.9% for rivaroxaban. More than 93% of reinitiations were with the index NOAC. Patients starting on dabigatran were more likely to switch OAC therapy than those starting on apixaban; ORs 4.28 (95% CI 3.24 to 5.65) for dabigatran and 1.89 (95% CI 1.49 to 2.39) for rivaroxaban. Severely reduced renal function was a predictor of any discontinuation, OR 1.77 (95% CI 1.28 to 2.44).ConclusionWhile the majority of patients with NVAF in the UK initiating NOAC treatment received continuous therapy in the first year of treatment, a substantial proportion of patients experienced gaps in treatment leaving them less protected against thromboembolism during these periods.

Authors: Harbitz Martin Bruusgaard , Brandstorp Helen , Gaski Margrete 
Published: October 2019

ObjectiveThe aim of this study is to identify and analyse rural general practice patients’ experiences of hazards and harm that comprise adverse events, and their strategies for coping with them.DesignInterview study using systematic text condensation and coping strategy theory in an abductive analysis process.SettingNine rural general practice clinics in Norway.ParticipantsTwenty participants, aged 21–79 years, all presenting with recent onset of somatic and/or psychiatric complaints.ResultsParticipating rural general practice patients described their experiences of a variety of hazards and harms. Their three most discussed cognitive and behavioural coping strategies were: (1) to accept the events; (2) to confront them and (3) to engage in planful problem-solving. While the participants demonstrated a tendency toward accepting hazards and harm that their regular general practitioner created, they were often willing to confront those that locum (ie, substitute) general practitioners created. Participants used planful problem-solving in situations they deemed hazardous, such as breaches of confidentiality or not being taken seriously, as well as during potential/actual emergencies.ConclusionsPatients at rural general practice clinics actively identify and respond to hazards and harm, applying three coping strategies. Thus, patients themselves may serve as an important safety barrier against hazards and harm; their potential contributions to improving patient safety must be appreciated accordingly and reflected in future research as well as in everyday clinical practice.

Published: October 2019

IntroductionCardiovascular diseases (CVDs) are among the leading causes of death globally. Electronic health records (EHRs) provide a rich data source for research on CVD risk factors, treatments and outcomes. Researchers must be confident in the validity of diagnoses in EHRs, particularly when diagnosis definitions and use of EHRs change over time. Our systematic review provides an up-to-date appraisal of the validity of stroke, acute coronary syndrome (ACS) and heart failure (HF) diagnoses in European primary and secondary care EHRs.Methods and analysisWe will systematically review the published and grey literature to identify studies validating diagnoses of stroke, ACS and HF in European EHRs. MEDLINE, EMBASE, SCOPUS, Web of Science, Cochrane Library, OpenGrey and EThOS will be searched from the dates of inception to April 2019. A prespecified search strategy of subject headings and free-text terms in the title and abstract will be used. Two reviewers will independently screen titles and abstracts to identify eligible studies, followed by full-text review. We require studies to compare clinical codes with a suitable reference standard. Additionally, at least one validation measure (sensitivity, specificity, positive predictive value or negative predictive value) or raw data, for the calculation of a validation measure, is necessary. We will then extract data from the eligible studies using standardised tables and assess risk of bias in individual studies using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Data will be synthesised into a narrative format and heterogeneity assessed. Meta-analysis will be considered when a sufficient number of homogeneous studies are available. The overall quality of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation tool.Ethics and disseminationThis is a systematic review, so it does not require ethical approval. Our results will be submitted for peer-review publication.PROSPERO registration numberCRD42019123898

BackgroundSince the Singapore Mental Health Study in 2010 which reported a 16.0% prevalence rate for current smokers and 4.5% for nicotine dependence, new anti-smoking strategies have been implemented. The aim of this study was to compare smoking trends from the 2010 study with the second Singapore Mental Health Study in 2016 (SMHS 2016).MethodsA survey of 6126 individuals aged 18 years and above randomly selected among Singapore residents was conducted using the same methodology as the 2010 study. The measures used in this analysis were sociodemographic questions, the Composite International Diagnostic Interview which assessed for psychiatric disorders, the Fagerstrom Test for Nicotine Dependence and a list of chronic physical conditions that were prevalent in Singapore. Logistic regression analyses were used to test for associations between smoking/nicotine-dependence and other measures.ResultsIn the SMHS 2016, 16.1% were current smokers and 3.3% were nicotine-dependent. As compared with non-smokers, current smokers were more likely to be younger, male gender, of ethnic minority and had lower/vocational education level. Younger age, male gender, lower/vocational education and psychiatric disorders (major depression, bipolar disorder and alcohol use disorders) predicted nicotine dependence. No associations were found between nicotine dependence and any of the chronic conditions.ConclusionThe prevalence of current smokers in the population has plateaued while that of nicotine dependence has decreased from 2010. However, the study did not investigate the use of e-cigarettes. Inequalities in smoking and nicotine dependence continue to pervade the population particularly among those of ethnic minority, lower/vocational education and the mentally ill.
Nutritional services for children in Beira, Mozambique: a study reporting on participatory use of data to generate quality improvement recommendations

BackgroundExisting literature suggest frequent gaps in the quality of care (QoC) provided to children with malnutrition in low-income and middle-income countries. Beira is the second largest city in Mozambique. This study included two phases: phase 1 was a systematic assessment of the QoC provided to malnourished children in Beira; phase 2 aimed at using findings of the assessment to develop recommendations, with a participatory approach, to improve QoC.MethodsIn phase 1, all facilities offering nutritional care to children in Beira were included, and exit health outcomes were reviewed against international SPHERE standards. A sample of four (66%) facilities was randomly selected for a comprehensive assessment of all areas contributing to QoC using an adapted WHO tool. In phase 2, key stakeholders were identified, and using a participatory approach, a list of actions for improving the QoC for malnourished children was agreed.ResultsIn phase 1, outcomes of 1428 children with either severe acute malnutrition or moderate acute malnutrition (MAM) were reviewed. In-hospital recovery rate (70.1%) was almost in line with the SPHERE standard (75%), while at outpatient level, it was significantly lower (48.2%, risk ratio (RR) 0.68, p<0.0001). Recovery rate was significantly lower in HIV seropositive compared with seronegative (39.2% vs 52.8%, RR 1.34, p=0.005). High heterogeneity in MAM recovery rate was detected among facilities (range 32.5%–61.0%). Overall, out of all domains contributing to QoC in the sample, 28/46 (60.8%) indicated suboptimal care with significant health hazards and 13/46 (28.2%) indicated totally inadequate care with severe health hazards. In phase 2, a list of 38 actions to improve QoC for malnourished children was agreed among 33 local and national stakeholders.ConclusionsLarge heterogeneity in QoC for malnourished children in Beria was detected. The study documents a concrete example of using data proactively, for agreeing actions to improve QoC.
Differential relationship between state-level minimum wage and infant mortality risk among US infants born to white and black mothers

Published: October 2019

BackgroundCompared to other Organisation for Economic Co-operation and Development (OECD) nations, US infant mortality rates (IMRs) are particularly high. These differences are partially driven by racial disparities, with non-Hispanic black having IMRs that are twice those of non-Hispanic white. Income inequality (the gap between rich and poor) is associated with infant mortality. One proposed way to decrease income inequality (and possibly to improve birth outcomes) is to increase the minimum wage. We aimed to elucidate the relationship between state-level minimum wage and infant mortality risk using individual-level and state-level data. We also determined whether observed associations were heterogeneous across racial groups.MethodsData were from US Vital Statistics 2010 Cohort Linked Birth and Infant Death records and the 2010 US Bureau of Labor Statistics. We fit multilevel logistic models to test whether state minimum wage was associated with infant mortality. Minimum wage was standardised using the z-transformation and was dichotomised (high vs low) at the 75th percentile. Analyses were stratified by mother's race (non-Hispanic black vs non-Hispanic white).ResultsHigh minimum wage (adjusted OR (AOR)=0.93, 95% CI 0.83 to 1.03) was associated with decreased odds of infant mortality but was not statistically significant. High minimum wage was significantly associated with reduced infant mortality among non-Hispanic black infants (AOR=0.80, 95% CI 0.68 to 0.94) but not among non-Hispanic white infants (AOR=1.04, 95% CI 0.92 to 1.17).ConclusionsIncreasing the minimum wage might be beneficial to infant health, especially among non-Hispanic black infants, and thus might decrease the racial disparity in infant mortality.
