Exploratory cluster randomised controlled trial of shared care development for long-term mental illness. Effectiveness of counselling patients on physical activity in general practice: cluster randomised controlled trial. Five years of lifestyle intervention improved self-reported mental and physical health in a general population: the Inter99 study.
Primary care clinicians have a considerable amount of contact with patients suffering from long-term mental illness. The United Kingdom's National Health Service now requires general practices to contribute more systematically to care for this group of patients.
                To determine the effects of Mental Health Link, a facilitation-based quality improvement programme designed to improve communication between the teams and systems of care within general practice. Design of study: Exploratory cluster randomised controlled trial.
                Twenty-three urban general practices and associated community mental health teams.
                Practices were randomised to service development as usual or to the Mental Health Link programme. Questionnaires and an audit of notes assessed 335 patients' satisfaction, unmet need, mental health status, processes of mental and physical care, and general practitioners' satisfaction with services and beliefs about service development. Service use and intervention costs were also measured.
                There were no significant differences in patients' perception of their unmet need, satisfaction or general health. Intervention patients had fewer psychiatric relapses than control patients (mean = 0.39 versus 0.71, respectively, P = 0.02) but there were no differences in documented processes of care. Intervention practitioners were more satisfied and services improved significantly for intervention practices. There was an additional mean direct cost of pound 63 per patient with long-term mental illness for the intervention compared with the control.
                Significant differences were seen in relapse rates and practitioner satisfaction. Improvements in service development did not translate into documented improvements in care. This could be explained by the intervention working via the improvements in informal shared care developed through better link working. This type of facilitated intervention tailored to context has the potential to improve care and interface working. To assess the long term effectiveness of the "green prescription" programme, a clinician based initiative in general practice that provides counselling on physical activity.
                Cluster randomised controlled trial. Practices were randomised before systematic screening and recruitment of patients.
                42 rural and urban general practices in one region of New Zealand.
                All sedentary 40-79 year old patients visiting their general practitioner during the study's recruitment period.
                General practitioners were prompted by the patient to give oral and written advice on physical activity during usual consultations. Exercise specialists continued support by telephone and post. Control patients received usual care.
                Change in physical activity, quality of life (as measured by the "short form 36" (SF-36) questionnaire), cardiovascular risk (Framingham and D'Agostino equations), and blood pressure over a 12 month period.
                74% (117/159) of general practitioners and 66% (878/1322) of screened eligible patients participated in the study. The follow up rate was 85% (750/878). Mean total energy expenditure increased by 9.4 kcal/kg/week (P=0.001) and leisure exercise by 2.7 kcal/kg/week (P=0.02) or 34 minutes/week more in the intervention group than in the control group (P=0.04). The proportion of the intervention group undertaking 2.5 hours/week of leisure exercise increased by 9.72% (P=0.003) more than in the control group (number needed to treat=10.3). SF-36 measures of self rated "general health," "role physical," "vitality," and "bodily pain" improved significantly more in the intervention group (P<0.05). A trend towards decreasing blood pressure became apparent but no significant difference in four year risk of coronary heart disease.
                Counselling patients in general practice on exercise is effective in increasing physical activity and improving quality of life over 12 months. Self-reported health has been shown to predict mortality. We lack knowledge on whether a lifestyle intervention can improve self-reported mental and physical health in a general population.
                Inter99, Denmark (1999-2006) is a randomised population-based intervention study. We screened for ischemic heart disease and repeatedly offered advice and assistance to obtain a healthier lifestyle. Health related quality of life was measured by Short Form 12 (SF-12); completed by 9322 at baseline and 7719 at five-year follow-up. In linear mixed models we investigated the effect of the intervention on self-reported health over time.
                At baseline men had higher physical health-component scores (PCS) than women. Living with a partner, being employed, and being healthy was associated with high PCS. The mental health-component scores (MCS) showed the same socio-demographic differences, except that MCS increased with age. Significantly fewer participants in the intervention groups had decreased their PCS and MCS compared with the control group. Adjusted multilevel analyses confirmed that the intervention significantly improved physical- (p=0.008) and mental health (p<0.001) over time compared with the control group.
                Screening for ischemic heart disease and offering lifestyle intervention had a significantly beneficial effect on mental and physical self-reported health in the long term in a general population.
General physical health could lead to people with serious mental illness accessing more health services which, in turn, could mean they see longer term benefits such as reduced mortality or morbidity. On the other hand it is possible clinicians are expending much effort, time and financial expenditure on giving ineffective advice. This is an important area for good research reporting outcome of interest to carers and people with serious illnesses as well as researchers and fundholders.
