Polygenic risk score adds to a clinical risk score in the prediction of cardiovascular disease in a clinical setting.

BACKGROUND AND AIMS: A cardiovascular disease polygenic risk score (CVD-PRS) can stratify individuals into different categories of cardiovascular risk, but whether the addition of a CVD-PRS to clinical risk scores improves the identification of individuals at increased risk in a real-world clinical setting is unknown. METHODS: The Genetics and the Vascular Health Check Study (GENVASC) was embedded within the UK National Health Service Health Check (NHSHC) programme which invites individuals between 40-74 years of age without known CVD to attend an assessment in a UK general practice where CVD risk factors are measured and a CVD risk score (QRISK2) is calculated. Between 2012-2020, 44,141 individuals (55.7% females, 15.8% non-white) who attended an NHSHC in 147 participating practices across two counties in England were recruited and followed. When 195 individuals (cases) had suffered a major CVD event (CVD death, myocardial infarction or acute coronary syndrome, coronary revascularisation, stroke), 396 propensity-matched controls with a similar risk profile were identified, and a nested case-control genetic study undertaken to see if the addition of a CVD-PRS to QRISK2 in the form of an integrated risk tool (IRT) combined with QRISK2 would have identified more individuals at the time of their NHSHC as at high risk (QRISK2 10-year CVD risk of ≥10%), compared with QRISK2 alone. RESULTS: The distribution of the standardised CVD-PRS was significantly different in cases compared with controls (cases mean score .32; controls, -.18, P = 8.28×10-9). QRISK2 identified 61.5% (95% confidence interval [CI]: 54.3%-68.4%) of individuals who subsequently developed a major CVD event as being at high risk at their NHSHC, while the combination of QRISK2 and IRT identified 68.7% (95% CI: 61.7%-75.2%), a relative increase of 11.7% (P = 1×10-4). The odds ratio (OR) of being up-classified was 2.41 (95% CI: 1.03-5.64, P = .031) for cases compared with controls. In individuals aged 40-54 years, QRISK2 identified 26.0% (95% CI: 16.5%-37.6%) of those who developed a major CVD event, while the combination of QRISK2 and IRT identified 38.4% (95% CI: 27.2%-50.5%), indicating a stronger relative increase of 47.7% in the younger age group (P = .001). The combination of QRISK2 and IRT increased the proportion of additional cases identified similarly in women as in men, and in non-white ethnicities compared with white ethnicity. The findings were similar when the CVD-PRS was added to the atherosclerotic cardiovascular disease pooled cohort equations (ASCVD-PCE) or SCORE2 clinical scores. CONCLUSIONS: In a clinical setting, the addition of genetic information to clinical risk assessment significantly improved the identification of individuals who went on to have a major CVD event as being at high risk, especially among younger individuals. The findings provide important real-world evidence of the potential value of implementing a CVD-PRS into health systems.

Developing a toolkit for increasing the participation of black, Asian and minority ethnic communities in health and social care research.

BACKGROUND: It is recognised that Black, Asian and Minority Ethnic (BAME) populations are generally underrepresented in research studies. The key objective of this work was to develop an evidence based, practical toolkit to help researchers maximise recruitment of BAME groups in research. METHODS: Development of the toolkit was an iterative process overseen by an expert steering group. Key steps included a detailed literature review, feedback from focus groups (including researchers and BAME community members) and further workshops and communication with participants to review the draft and final versions. RESULTS: Poor recruitment of BAME populations in research is due to complex reasons, these include factors such as inadequate attention to recruitment strategies and planning, poor engagement with communities and individuals due to issues such as cultural competency of researchers, historical poor experience of participating in research, and lack of links with community networks. Other factors include language issues, relevant expertise in research team and a lack of adequate resources that might be required in recruitment of BAME populations. CONCLUSIONS: A toolkit was developed with key sections providing guidance on planning research and ensuring adequate engagement of communities and individuals. Together with sections suggesting how the research team can address training needs and adopt best practice. Researchers highlighted the issue of funding and how best to address BAME recruitment in grant applications, so a section on preparing a grant application was also included. The final toolkit document is practical, and includes examples of best practice and 'top tips' for researchers.

Effectiveness of the Transformation model, a model of care that integrates diabetes services across primary, secondary and community care: A retrospective study.

AIMS: The primary aim was to evaluate the effectiveness of a model integrating diabetes services across primary, secondary and community care (Transformation model). The secondary aim was to understand whether changes resulted from the model. METHODS: The model was implemented In Leicester, Leicestershire and Rutland (UK) across three clinical commissioning groups, the acute trust and accompanying stakeholders. One clinical commissioning group (Leicester City) implemented the entire model and was the primary evaluation population. A quasi-experimental interrupted time series design was employed. The primary outcome was number of Type 2 diabetes-related bed-days per 1000 patients. RESULTS: In the primary population, the mean number of Type 2 diabetes-related bed-days per 1000 patients was increasing before model implementation by 0.33/month (95% confidence interval: -0.07, 0.72), whereas it was decreasing after implementation by a mean value of -0.14/month (-0.33, 0.06); a statistically significant difference (p = 0.04). Secondary analyses showed: nationally, there was no significant change between the pre- and post-periods so it is unlikely that large secular change drove the improvement; the other two Leicestershire clinical commissioning groups saw improvement or stability; underlying processes worked as hypothesised overall; diabetes biomedical markers deteriorated in the primary care population suggesting a change in case-mix due to moving some patients out of secondary care. CONCLUSIONS: Given that the initial aim was to shift services from secondary to primary care without causing harm, an improvement is better than expected. This observational evaluation cannot show conclusively that improvements were due to the Transformation model, but secondary analyses support this.

Pharmacological management of South Asians with type 2 diabetes: Consensus recommendations from the South Asian Health Foundation.

South Asians constitute approximately 1.6 billion people from the Indian subcontinent, comprising Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka; and make up the largest diaspora globally. Compared to the White European population, this group is at a higher risk of developing type 2 diabetes along with cardiovascular, renal and eye complications. Over the recent years, a number of new therapies for type 2 diabetes have become available for which cardiovascular outcome trials (CVOTs) have been published. The recent ADA/EASD consensus guidelines on diabetes, pre-diabetes and cardiovascular diseases' offer a transitional shift in type 2 diabetes management. The new consensus recommendations are based on recent CVOTs, many of which had a representation of South Asian cohorts. In light of this new evidence, there is urgent need for an integrated, evidence-based, cost-effective and individualised approach specific for South Asians. This review takes into consideration the evidence from these CVOTs and provides best practice recommendations for optimal management of South Asian people with type 2 diabetes, alongside the previously published consensus report from South Asian Health Foundation in 2014 [1].

Intensive versus standard multifactorial cardiovascular risk factor control in screen-detected type 2 diabetes: 5-year and longer-term modelled outcomes of the ADDITION-Leicester study.

AIMS: Diabetes treatment algorithms recommend intensive intervention in those with a shorter duration of disease. Screening provides opportunities for earlier multifactorial cardiovascular risk factor control. Using data from the ADDITION-Leicester study (NCT00318032), we estimated the effects of this approach on modelled risk of diabetes-related complications in screen-detected patients. METHODS: A total of 345 (41% South Asian) people with screen-detected type 2 diabetes were cluster randomised to receive 5 years of (1) intensive multifactorial risk factor intervention or (2) standard treatment according to national guidance. Estimated 10 to 20-year risk of ischaemic heart disease, stroke, congestive cardiac failure, and death was calculated using UK-PDS risk equations. RESULTS: Compared with standard care, mean treatment differences for intensive management at 5 years were -11.7(95%CI: -15.0, -8.4) and -6.6(-8.8, -4.4) mmHg for systolic and diastolic blood pressure, respectively; -0.27 (-0.66, -0.26) % for HbA1c; and -0.46(-0.66; -0.26), -0.34 (-0.51; -0.18), and -0.19 (-0.28; -0.10) mmol/L for total cholesterol, LDL-cholesterol, and triglycerides, respectively. There was no significant weight gain in the intensive group despite additional medication use. Modelled risks were consistently lower for intensively managed patients. Absolute risk reduction associated with intensive treatment at 10 and 20 years were 3.5% and 6.2% for ischaemic heart disease and 6.3% and 8.8% for stroke. Risk reduction for congestive heart failure plateaued after 15 years at 5.3%. No differences were observed for blindness and all-cause death. CONCLUSION: Intensive multifactorial intervention in a multi-ethnic population with screen-detected type 2 diabetes results in sustained improvements in modelled ischaemic heart disease, stroke, and congestive cardiac failure.

A community based primary prevention programme for type 2 diabetes integrating identification and lifestyle intervention for prevention: the Let's Prevent Diabetes cluster randomised controlled trial.

OBJECTIVES: Prevention of type 2 diabetes (T2DM) is a priority in healthcare, but there is a lack of evidence investigating how to effectively translate prevention research into a UK primary care setting. We assessed whether a structured education programme targeting lifestyle and behaviour change was effective at preventing progression to T2DM in people with pre-diabetes. MATERIALS AND METHODS: Forty-four general practices were randomised to receive either standard care or a 6hour group structured education programme with an annual refresher course, and regular phone contact. Participants were followed up for 3years. The primary outcome was progression to T2DM. RESULTS: Eight hundred and eighty participants were included (36% female, mean age 64years, 16% ethnic minority group); 131 participants developed T2DM. There was a non-significant 26% reduced risk of developing T2DM in the intervention arm compared to standard care (HR 0.74, 95% CI 0.48, 1.14, p=0.18). The reduction in T2DM risk when excluding those who did not attend the initial education session was also non-significant (HR 0.65, 0.41, 1.03, p=0.07). There were statistically significant improvements in HbA1c (-0.06, -0.11, -0.01), LDL cholesterol (-0.08, -0.15, -0.01), sedentary time (-26.29, -45.26, -7.32) and step count (498.15, 162.10, 834.20) when data were analysed across all time points. CONCLUSIONS: This study suggests that a relatively low resource, pragmatic diabetes prevention programme resulted in modest benefits to biomedical, lifestyle and psychosocial outcomes, however the reduction to the risk of T2DM did not reach significance. The findings have important implications for future research and primary care.

Study protocol for the use of time series forecasting and risk analyses to investigate the effect of the COVID-19 pandemic on hospital admissions associated with new-onset disability and frailty in a national, linked electronic health data setting.

INTRODUCTION: Older people were at particular risk of morbidity and mortality during COVID-19. Consequently, they experienced formal (externally imposed) and informal (self-imposed) periods of social isolation and quarantine. This is hypothesised to have led to physical deconditioning, new-onset disability and frailty. Disability and frailty are not routinely collated at population level but are associated with increased risk of falls and fractures, which result in hospital admissions. First, we will examine incidence of falls and fractures during COVID-19 (January 2020-March 2022), focusing on differences between incidence over time against expected rates based on historical data, to determine whether there is evidence of new-onset disability and frailty. Second, we will examine whether those with reported SARS-CoV-2 were at higher risk of falls and fractures. METHODS AND ANALYSIS: This study uses the Office for National Statistics (ONS) Public Health Data Asset, a linked population-level dataset combining administrative health records with sociodemographic data of the 2011 Census and National Immunisation Management System COVID-19 vaccination data for England. Administrative hospital records will be extracted based on specific fracture-centric International Classification of Diseases-10 codes in years preceding COVID-19 (2011-2020). Historical episode frequency will be used to predict expected admissions during pandemic years using time series modelling, if COVID-19 had not occurred. Those predicted admission figures will be compared with actual admissions to assess changes in hospital admissions due to public health measures comprising the pandemic response. Hospital admissions in prepandemic years will be stratified by age and geographical characteristics and averaged, then compared with pandemic year admissions to assess more granular changes. Risk modelling will assess risk of experiencing a fall, fracture or frail fall and fracture, if they have reported a positive case of COVID-19. The combination of these techniques will provide insight into changes in hospital admissions from the COVID-19 pandemic. ETHICS AND DISSEMINATION: This study has approval from the National Statistician's Data Ethics Advisory Committee (NSDEC(20)12). Results will be made available to other researchers via academic publication and shared via the ONS website.

Evaluating the clinical effectiveness of the NHS Health Check programme: a prospective analysis in the Genetics and Vascular Health Check (GENVASC) study.

OBJECTIVE: The aim of the study was to assess the clinical effectiveness of the national cardiovascular disease (CVD) prevention programme-National Health Service Health Check (NHSHC) in reduction of CVD risk. DESIGN: Prospective cohort study. SETTING: 147 primary care practices in Leicestershire and Northamptonshire in England, UK. PARTICIPANTS: 27 888 individuals undergoing NHSHC with a minimum of 18 months of follow-up data. OUTCOME MEASURES: The primary outcomes were NHSHC attributed detection of CVD risk factors, prescription of medications, changes in values of individual risk factors and frequency of follow-up. RESULTS: At recruitment, 18% of participants had high CVD risk (10%-20% 10-year risk) and 4% very high CVD risk (>20% 10-year risk). New diagnoses or hypertension (HTN) was made in 2.3% participants, hypercholesterolaemia in 0.25% and diabetes mellitus in 0.9%. New prescription of stains and antihypertensive medications was observed in 5.4% and 5.4% of participants, respectively. Total cholesterol was decreased on average by 0.38 mmol/L (95% CI -0.34 to -0.41) and 1.71 mmol/L (-1.48 to -1.94) in patients with initial cholesterol >5 mmol/L and >7.5 mmol/L, respectively. Systolic blood pressure was decreased on average by 2.9 mm Hg (-2.3 to -3.7), 15.7 mm Hg (-14.1 to -17.5) and 33.4 mm Hg (-29.4 to -37.7), in patients with grade 1, 2 and 3 HTN, respectively. About one out of three patients with increased CVD risk had no record of follow-up or treatment. CONCLUSIONS: Majority of patients identified with increased CVD risk through the NHSHC were followed up and received effective clinical interventions. However, one-third of high CVD risk patients had no follow-up and therefore did not receive any treatment. Our study highlights areas of focus which could improve the effectiveness of the programme. TRIAL REGISTRATION NUMBER: NCT04417387.

A cost comparison of an enhanced primary care diabetes service and standard care.

BACKGROUND: Type 2 diabetes, which contributes 90% of all cases of diabetes mellitus is now mostly managed in the primary care settings in the UK and other advanced health care systems. The UK National Health Service as a whole could potentially benefit if more patients were managed in primary care settings since primary care-based care is likely to be more cost-effective. We initially compared eight larger general practices (Enhanced practices) in Leicester, UK with neighbouring smaller practices (Core practices) matched for comparable demographic characteristics. Even though this initial study did not find any statistically significant differences in terms of clinical outcomes there was trend in favour of the enhanced practices. In this current study, we conducted a cost comparison of enhanced practice model of diabetes care, to standard care delivered in the core practices. METHODS: Data and information were combined from a number of sources and a cost comparison evaluation was carried out in WinBUGs. A probabilistic approach was taken, to allow uncertainty to be included around analysis parameters where appropriate. The analysis evaluated a straight-forward cost comparison of enhanced versus standard care. RESULTS: The cost per person with diabetes per year was £255 (95% CrI 175, 380) in the core practices and £173 (95% CrI 96, 291) in the enhanced practices, resulting in an annual cost saving of -£83 (95% CrI -148, -28) per patient. If the enhanced model of diabetes care were delivered across all the practices in the UK, the cost would be £575,100,000 (95% CrI 320,700,000, 970,700,000), resulting in an annual cost saving of -276,200,000 (95% CrI -495,400,000, -94,480,000). CONCLUSION: A cost comparison analysis of our larger enhanced primary care based diabetes service confirms significant cost saving, probably driven by economies of scale. These benefits could be multiplied manifold if the service was implemented nationally.

Community-based testing of migrants for infectious diseases (COMBAT-ID): impact, acceptability and cost-effectiveness of identifying infectious diseases among migrants in primary care: protocol for an interrupted time-series, qualitative and health economic analysis.

BACKGROUND: Migration is a major global driver of population change. Certain migrants may be at increased risk of infectious diseases, including tuberculosis (TB), HIV, hepatitis B and hepatitis C, and have poorer outcomes. Early diagnosis and management of these infections can reduce morbidity, mortality and onward transmission and is supported by national guidelines. To date, screening initiatives have been sporadic and focused on individual diseases; systematic routine testing of migrant groups for multiple infections is rarely undertaken and its impact is unknown. We describe the protocol for the evaluation of acceptability, effectiveness and cost-effectiveness of an integrated approach to screening migrants for a range of infectious diseases in primary care. METHODS AND ANALYSIS: We will conduct a mixed-methods study which includes an observational cohort with interrupted time-series analysis before and after the introduction of routine screening of migrants for infectious diseases (latent TB, HIV, hepatitis B and hepatitis C) when first registering with primary care within Leicester, UK. We will assess trends in the monthly number and rate of testing and diagnosis for latent TB, HIV, hepatitis B and hepatitis C to determine the effect of the policy change using segmented regression analyses at monthly time-points. Concurrently, we will undertake an integrated qualitative sub-study to understand the views of migrants and healthcare professionals to the new testing policy in primary care. Finally, we will evaluate the cost-effectiveness of combined infection testing for migrants in primary care. ETHICS AND DISSEMINATION: The study has received HRA and NHS approvals for both the interrupted time-series analysis (16/SC/0127) and the qualitative sub-study (16/EM/0159). For the interrupted time-series analysis we will only use fully anonymised data. For the qualitative sub-study, we will gain written, informed, consent. Dissemination of the results will be through local and national meetings/conferences as well as publications in peer-reviewed journals.

Educational interventions in kidney disease care: a systematic review of randomized trials.

BACKGROUND: There is increasing evidence that educational interventions aimed at empowering patients are successful in chronic disease management. Our aim was to conduct a systematic review of the effectiveness of such educational interventions in people with kidney disease. SYSTEMATIC REVIEW: A comprehensive search strategy was applied by using major electronic databases from 1980 to March 2007. Researchers independently reviewed titles and abstracts and extracted data from identified studies. SETTING & POPULATION: Patients in any of the following stages of chronic kidney disease: early, predialysis, and dialysis. Kidney transplant recipients were excluded because this group has additional educational needs that are beyond the scope of this review. SELECTION CRITERIA FOR STUDIES: Randomized controlled trials. INTERVENTIONS: Structured educational interventions (involving informational and psychological components) with usual care. OUTCOMES: Clinical, behavioral, psychological, and knowledge outcomes were considered. RESULTS: 22 studies were identified involving a wide range of multicomponent interventions with variable aims and outcomes depending on the area of kidney disease care. 18 studies provided significant results for at least 1 of the outcomes. The majority of studies aimed to improve diet and/or fluid concordance in dialysis patients and involved short- and medium-term follow-up. A single major long-term study was a 20-year follow-up of a predialysis educational intervention that showed increased survival rates. No study was found that addressed chronic kidney disease at an earlier stage. LIMITATIONS: Meta-analysis was not possible because of study heterogeneity. CONCLUSIONS: Multicomponent structured educational interventions were effective in predialysis and dialysis care, but the quality of many studies was suboptimal. Effective frameworks to develop, implement, and evaluate educational interventions are required, especially those that target patients with early stages of chronic kidney disease. This could lead to possible prevention or delay in progression of kidney disease.

A cross sectional survey of secondary prevention measures in patients with peripheral arterial disease in primary care.

BACKGROUND: The National Service Framework for coronary heart disease (CHD) defines standards for the secondary prevention of cardiovascular disease in at risk individuals, including those with peripheral arterial disease (PAD). AIM: To assess current standards of secondary prevention and health monitoring in patients with PAD following a vascular procedure, and additionally compare care in patients with and without diagnosed CHD. METHODS: Indicators for this cross sectional survey were identified from national recommendations and evidence. A retrospective review was conducted of general practitioner records, for patients who were treated in hospital for PAD. RESULTS: Data were collected for 103 patients from 42 practices. Overall, prescribing was well achieved for antiplatelets but poor for statins. Standards of assessment of blood pressure, smoking status, and smoking cessation advice were high. However, approximately only half of the patients received advice about exercise or had their body mass index checked. Furthermore, for all indicators, standards of care for patients who additionally had a diagnosis of CHD were better than for patients without CHD. CONCLUSION: The cross sectional survey suggested the treatment received by some patients with established PAD is substandard. There is considerable potential to increase secondary prevention of CHD in patients with PAD disease in primary care.

Dietary habits of young people attending secondary schools serving a multiethnic, inner-city community in the UK.

BACKGROUND: Childhood obesity is an escalating health concern with important implications, including increased risk of type 2 diabetes and cardiovascular disease. Although South Asians in the UK have an increased risk of developing these conditions, detailed studies on their lifestyles including the dietary habits of young people are scarce. METHODS: As part of an action research project, a food intake questionnaire was used to survey the dietary habits of 11-15-year olds attending five inner-city schools serving a predominantly South Asian population. Food choices were considered in the overall sample and in South Asians compared with white Europeans. RESULTS: 3418 (72% of registered pupils) responses were obtained. A subset of 3018 pupils could be categorised as either South Asian (86%) or white European (14%). Around one fifth of pupils started the school day without eating anything. Responses indicated high consumption of "negative" foods such as sweets, including Asian sweets (63%), but lower rates for "positive" foods such as vegetables (34%). In the full sample, 26% said they had consumed more than one can of sugar-sweetened fizzy drink and 17% reported eating more than one packet of full-fat crisps on the previous day. Poor dietary habits were indicated in both South Asian and white European pupils. CONCLUSIONS: Our large-scale survey confirmed poor dietary habits in secondary school pupils from a multiethnic community. Urgent efforts are needed to find ways of encouraging healthy lifestyles, particularly in populations with a high risk of developing cardiovascular disease and type 2 diabetes.

Barriers and Facilitators to Healthy Lifestyle Changes in Minority Ethnic Populations in the UK: a Narrative Review.

Minority ethnic populations experience a disproportionate burden of health inequalities compared with the rest of the population, including an increased risk of type 2 diabetes (T2DM). The purpose of this narrative review was to explore knowledge and attitudes around diabetes, physical activity and diet and identify barriers and facilitators to healthy lifestyle changes in minority ethnic populations in the UK. The narrative review focused on three key research topics in relation to barriers and facilitators to healthy lifestyle changes in minority adult ethnic populations: (i) knowledge and attitudes about diabetes risk; (ii) current behaviours and knowledge about physical activity and diet; and (iii) barriers and facilitators to living a healthier lifestyle. Nearly all of the studies that we identified reported on South Asian minority ethnic populations; we found very few studies on other minority ethnic populations. Among South Asian communities, there was generally a good understanding of diabetes and its associated risk factors. However, knowledge about the levels of physical activity required to gain health benefits was relatively poor and eating patterns varied. Barriers to healthy lifestyle changes identified included language barriers, prioritising work over physical activity to provide for the family, cultural barriers with regard to serving and eating traditional food, different perceptions of a healthy body weight and fear of racial harassment or abuse when exercising. Additional barriers for South Asian women included expectations to remain in the home, fear for personal safety, lack of same gender venues and concerns over the acceptability of wearing 'western' exercise clothing. Facilitators included concern that weight gain might compromise family/carer responsibilities, desire to be healthy, T2DM diagnosis and exercise classes held in 'safe' environments such as places of worship. Our findings suggest that South Asian communities are less likely to engage in physical activity than White populations and highlight the need for health promotion strategies to engage people in these communities. There is a gap in knowledge with regard to diabetes, physical activity, diet and barriers to healthy lifestyle changes among other ethnic minority populations in the UK; we recommend further research in this area.

Feasibility of a structured group education session to improve self-management of blood pressure in people with chronic kidney disease: an open randomised pilot trial.

Objectives We aimed to test, at pilot level, a structured group educational intervention to improve self-management of blood pressure in people with chronic kidney disease (CKD). The current paper explores patient acceptability of the intervention. Design This was an open randomised pilot trial. Participants were randomly assigned to either: A control group (n=41) receiving standard clinical management of hypertension. An intervention group (n=40) receiving standard clinical care plus the educational intervention. Setting Renal outpatient clinics at a single study centre. Participants Patients with early CKD and hypertension were identified and approached for recruitment. Intervention An evidence-based structured group educational intervention (CHEERS) using the principles of social cognitive theory to improve knowledge and self-management skills. Outcomes Recruitment, uptake of the intervention and patient satisfaction were evaluated to explore patient acceptability of the intervention and to determine any differences between patients regarding recruitment and retention. Measures Data on age, sex and ethnicity were collected for all patients approached to take part. For recruited patients, data were also collected on self-efficacy (ability to self-manage). Reasons given by patients declining to take part were recorded. Patients attending the educational session also completed an evaluation form to assess satisfaction. Results A total of 267 patients were approached, and 30% were randomly assigned. Lack of time (48%) and lack of interest (44%) were the main reasons cited for non-participation in the study. Men were significantly more likely to be recruited (p=0.048). The intervention was rated enjoyable and useful by 100% of participants. However, 37.5% of the intervention group failed to attend the educational session after recruitment. Participants failing to attend were significantly more likely to be older (p=0.039) and have lower self-efficacy (p=0.034). Conclusion The findings suggest that delivering and evaluating an effective structured group educational intervention to promote better blood pressure control in patients with CKD would be challenging in the current context of kidney care.

Screening for the metabolic syndrome using simple anthropometric measurements in south Asian and white Europeans: a population-based screening study. The Leicester Ethnic Atherosclerosis and Diabetes Risk (LEADER) Study.

AIMS: To estimate the prevalence of metabolic syndrome in a general population sample of south Asians and white Europeans and compare predictors of metabolic syndrome, using ethnic specific definitions of obesity. METHODS: 3099 participants (71.4% white European, 28.6% south Asian) aged 40-75 years were screened using a 75 g oral glucose tolerance test. Metabolic syndrome was defined using National Cholesterol Education Programme and International Diabetes Federation definitions. We compared sensitivity, specificity and area under the curve of waist circumference, body mass index and waist-hip ratio. RESULTS: The prevalence of metabolic syndrome using the definitions above was 29.9% (29.2% south Asian, 30.2% white European), and 34.4% (34.2% south Asian, 34.5% white European), respectively. Using the National Cholesterol Education Programme definition, waist circumference was significantly more predictive of metabolic syndrome than body mass index or waist-hip ratio. The area under the curve for waist circumference was 0.75 (95% CI: 0.69-0.80) and 0.76 (0.72-0.81) for south Asian men and women; 0.83 (0.80-0.85) and 0.80 (0.77-0.82) for white European men and women. CONCLUSIONS: The prevalence of metabolic syndrome is high in both south Asian and white European populations. Waist circumference is a simple and effective measure for predicting metabolic syndrome in different populations.

Screening for type 2 diabetes in a multiethnic setting using known risk factors to identify those at high risk: a cross-sectional study.

INTRODUCTION: Screening enables the identification of type 2 diabetes mellitus (T2DM) during its asymptomatic stage and therefore allows early intervention which may lead to fewer complications and improve outcomes. A targeted screening program was carried out in a United Kingdom (UK) multiethnic population to identify those with abnormal glucose tolerance. METHODS: A sample of individuals aged 25-75 years (40-75 white European) with at least one risk factor for T2DM were invited for screening from 17 Leicestershire (UK) general practices or through a health awareness campaign. All participants received a 75 g oral glucose tolerance test, cardiovascular risk assessment, detailed medical and family histories and anthropometric measurements. RESULTS: In the 3,225 participants who were screened. 640 (20%) were found to have some form of abnormal glucose tolerance of whom 4% had T2DM, 3% impaired fasting glucose (IFG), 10% impaired glucose tolerance (IGT) and 3% both IFG and IGT. The odds of detecting IGT was approximately 60% greater (confounder-adjusted odds ratios [OR] 1.67 [1.22-2.29]) in the South Asian population. CONCLUSIONS: Around one in five people who had targeted screening have IGT, IFG or T2DM, with a higher prevalence in those of South Asian origin. The prevalence of undetected T2DM is lower in South Asians compared to previously published studies and maybe due to increased awareness of this group being at high risk.

Raising awareness of chronic kidney disease among South Asians and primary care: the ABLE project.

UNLABELLED: Established renal failure as a complication of diabetes in 10 times greater in South Asians than in Caucasians. The objectives were: (1) to develop methods to increase community awareness and (2) to support general practices to improve chronic kidney disease (CKD) detection and management. The methods include: 1. Action research approach. 2. Public health education programme. 3. Audit in control and intervention practices. 4. Post-intervention focus group study determining changes in knowledge. 5. Evaluation and dissemination in community and primary care. RESULTS: An evaluation of innovative resources and peer educator model demonstrated a positive feedback, increased knowledge and evidence of positive lifestyle change. Intervention with the practices has demonstrated the need to improve some aspects of CKD management. CONCLUSION: This unique initiative has helped to identify practical strategies to address CKD awareness in these communities. However, the successful elements need to become part of mainstream National health Service and not just delivered by short-term projects.

Educational needs for blood pressure control in chronic kidney disease.

Strict blood pressure control reduces the risk of adverse outcomes in chronic kidney disease but is difficult to achieve. To inform the design of an educational intervention for patients with chronic kidney disease and hypertension, we used focus groups to identify key patient issues, from both patient and healthcare professional perspectives. Framework methodology was used to analyse data and patient confusion emerged as the core concept. This was both an effect and, in some cases, a cause of the six key themes identified: lack of basic knowledge; conflicting advice; nature of diagnosis; changes in evidence-based practice; views on patient empowerment and views on the patient-health professional relationship. Educational needs identified involved addressing confusion by increasing both knowledge and motivation. In people with chronic kidney disease, confusion can lead to a lack of motivation and negative views that need to be addressed through appropriate education and support.
