| Summary: | Objective To determine the effectiveness of an intervention to enhance self management support for patients with chronic conditions in UK primary care. Design Pragmatic, two arm, cluster randomised controlled trial. Setting General practices, serving a population in northwest England with high levels of deprivation. Participants 5599 patients with a diagnosis of diabetes (n=2546), chronic obstructive pulmonary disease (n=1634), and irritable bowel syndrome(n=1419) from 43 practices (19 intervention and 22 control practices). Intervention Practice level training in a whole systems approach to self management support. Practices were trained to use a range of resources: a tool to assess the support needs of patients, guidebooks on self management, and a web based directory of local self management resources. Training facilitators were employed by the health management organisation. Main Outcome Measures Primary outcomes were shared decision making, self efficacy, and generic health related quality of life measured at 12 months. Secondary outcomes were general health, social or role limitations, energy and vitality, psychological wellbeing, self care activity,and enablement. Results We randomised 44 practices and recruited 5599 patients, representing 43% of the eligible population on the practice lists. 4533 patients (81.0%) completed the six month follow-up and 4076 (72.8%)the 12 month follow-up.No statistically significant differences were found between patients attending trained practices and those attending control practices on any of the primary or secondary outcomes. All effect size estimates were well below the prespecified threshold of clinically important difference.
