Adapted cardiac rehabilitation for people with sub-acute, mild-to-moderate stroke: a mixed methods feasibility study.

OBJECTIVE: To determine the recruitment strategy, acceptability, adherence, outcome measures, and adverse events for a definitive study that will explore adapted cardiac rehabilitation (CR) for people post-stroke with mild-to-moderate severity stroke in the sub-acute stage of recovery. DESIGN: Mixed methods feasibility study. SETTING: Acute hospital setting, neurology outpatients and community hospitals. PARTICIPANTS: 32 participants with stroke (mean age: 64.4 years) of median National Institutes of Health Stroke Scale (NIHSS) score 2 (range: 0 to 6) within six months of stroke. INTERVENTION: All participants attended six weeks, adapted CR within one to six months after a stroke. A combined class with people post cardiac event. MAIN OUTCOME MEASURES: Incremental shuttle walk test (ISWT), blood pressure, heart rate, weight, body mass index, quality of life, fatigue, anxiety and depression, tone, falls, stroke attitude and knowledge, physical activity (accelerometry) and functional ability. QUALITATIVE: Interviews with participants, non-participants and people post-cardiac event. Focus groups with Stroke and CR teams. RESULTS: 32 participants were recruited. The programme was acceptable to people with mild stroke (NIHSS<3) and people post cardiac events; 80% of classes attended, a mean of 9.6 classes, with six drop-outs. The ISWT was an acceptable outcome measure (for NIHSS<3) and most measures showed positive changes. There was one adverse event. CONCLUSION: A definitive study to determine the effect of six weeks of adapted CR on cardiorespiratory fitness (CRf) in people who have had a mild severity stroke (NIHSS<3) in the sub-acute phase of recovery, is feasible. Teams need specialist education and support. A more specialist service may be needed for people with a stroke severity defined by NIHSS>2. CLINICAL TRIAL REGISTRATION NUMBER: ISRCTN14861846.

Leisure-time physical activity and life expectancy in people with cardiometabolic multimorbidity and depression.

BACKGROUND: Whether and to what extent leisure-time physical activity at the recommended levels of 150-min moderate activity is associated with survival in people with cardiometabolic multimorbidity and depression is unknown. METHODS: UK Biobank participants were classified into groups: (i) no disease; (ii) diabetes; (iii) cardiovascular disease (CVD); (iv) depression; (v) diabetes and CVD; (vi) diabetes and depression; (vii) CVD and depression; (viii) diabetes, CVD and depression. Leisure-time physical activity was categorized as active (meeting recommendations) or inactive. Survival models were applied to estimate life expectancy. RESULTS: A total of 480 940 participants were included (median age, 58 years; 46% men; 95% white), of whom 74% with cardiometabolic multimorbidity and depression were inactive. During a mean follow-up of 7 years, 11 006 deaths occurred. At age of 45 years, being physically active was associated with 2.34 (95% confidence interval: 0.93, 3.54) additional years of life compared with being inactive in participants with diabetes; corresponding estimates were 2.28 (1.40, 3.16) for CVD; 2.15 (0.05, 4.26) for diabetes and CVD; and 1.58 (1.27, 1.89) for no disease. Participants with a combination of diabetes, CVD and depression, being active was associated with 6.81 (-1.50, 15.31) additional years compared with being inactive; corresponding estimates were 3.07 (-2.46, 8.59) for diabetes and depression; 2.34 (-1.24, 5.91) for CVD and depression; and 0.80 (-0.46, 2.05) for depression. A similar pattern was found at 65 years. CONCLUSIONS: Meeting the recommended level of physical activity was associated with a longer life expectancy in people with cardiometabolic multimorbidity but not in those with depression.

Assessment of response rates and yields for Two opportunistic Tools for Early detection of Non-diabetic hyperglycaemia and Diabetes (ATTEND). A randomised controlled trial and cost-effectiveness analysis.

AIMS: To assess the opportunistic use in primary care of a computer risk score versus a self-assessment risk score for undiagnosed type 2 diabetes. METHODS: We conducted a randomised controlled trial in 11 primary care practices in the UK. 577 patients aged 40-75years with no current diagnosis of type 2 diabetes were recruited to a computer based risk score (Leicester Practice Computer Risk Score (LPCRS)) or a patient self-assessment score (Leicester Self-Assessment Score (LSAS)). RESULTS: The rate of self-referral blood tests was significantly higher for the LPCRS compared to the LSAS, 118.98 (95% CI: 102.85, 137.64) per 1000 high-risk patient years of follow-up compared to 92.14 (95% CI: 78.25, 108.49), p=0.022. Combined rate of diagnosis of type 2 diabetes and those at risk of developing the disease (i.e. impaired glucose tolerance (IGT) or impaired fasting glucose (IFG)) was similar between the two arms, 15.12 (95% CI: 9.11, 25.08) per 1000 high-risk patient years for LPCRS compared to 14.72 (95% CI: 9.59, 22.57) for the LSAS, p=0.699. For the base case scenario the cost per new case of type 2 diabetes diagnosed was lower for the LPCRS compared to the LSAS, £168 (95% Credible Interval (CrI): 76, 364), and £352 (95% CrI: 109, 1148), respectively. CONCLUSIONS: Compared to a self-assessment risk score, a computer based risk score resulted in greater attendance to an initial blood test and is potentially more cost-effective.

What do qualitative rapid assessment collections of macroinvertebrates represent? A comparison with extensive quantitative sampling.

It is a fundamental tenet of Rapid Biological Assessments (RBA) that the samples collected reflect the community from which they are drawn. As with any biological sampling, RBA collections are subject to sampling error resulting in the omission of some taxa. The aim of this study is to compare the composition of RBA samples with an estimate of community structure based on extensive quantitative sampling. We used logistic regression to explore the relationships between the frequency of a taxon being collected in an RBA sample and its biological and ecological traits, namely its abundance, distribution, body size and habit. RBA samples and quantitative estimates of community structure were made in riffles in the Kangaroo and Nepean Rivers, New South Wales, Australia. Single RBA samples may collect up to 63% of the taxa that are collected by extensive quantitative sampling at a site. The frequency of a taxon being recorded in an RBA sample was significantly and positively related to all traits tested indicating a bias in the collection methods towards large, abundant and widely distributed taxa. Accordingly, taxa missed by RBA sampling were generally small, narrowly distributed or rare. These findings enhance our understanding of what RBA samples represent, and the bias and source of errors associated with RBA sampling. This study also quantifies the utility of RBA methods for biodiversity assessment.

Effect of patient completed agenda forms and doctors' education about the agenda on the outcome of consultations: randomised controlled trial.

OBJECTIVE: To assess the effect of patient completed agenda forms for the consultation and doctors' education on identifying patients' agendas on the outcome of consultations. DESIGN: Randomised controlled trial. SETTING: General practices in Leicestershire and Nottinghamshire, United Kingdom. PARTICIPANTS: 46 general practitioners and 976 patients. INTERVENTIONS: Education for general practitioners, with an embedded clustered randomised controlled trial of a patient agenda form. MAIN OUTCOME MEASURES: Number of problems identified, time required to manage each problem, duration of consultations, number of problems raised after the doctor considered the consultation finished ("by the way" questions), and patient satisfaction. RESULTS: Data were available from 45 doctors (98%) and 857 patients (88%). The number of problems identified in each consultation increased by 0.2 (95% confidence interval 0.1 to 0.4) with the agenda form, by 0.3 (0.1 to 0.6) with education, and by 0.5 (0.3 to 0.7) with both interventions. The time required to manage each problem was not affected. The duration of consultations with the agenda form was increased by 0.9 minutes (0.3 to 1.5 minutes) and with the combined intervention by 1.9 minutes (1.0 to 2.8 minutes). Patient satisfaction with the depth of the doctor-patient relationship was increased with the agenda form. The occurrence of "by the way" presentations did not change. CONCLUSION: A patient completed agenda form before the consultation or general practitioner education about the agenda form, or both, enabled the identification of more problems in consultations even though consultations were longer.
