Effectiveness of the "7H" Intervention to Reduce Frequent Attendance in Primary Care

The main objective is to measure the effectiveness of a new intervention to decrease use of services of primary care frequent attenders (FA).Among the secondary objectives are to evaluate the cost-effectiveness and cost utility of the new intervention compared with usual care. METHODS: There will be a randomized controlled trial with cluster assignment. It will take place in the field of primary care in the city of Malaga.It will be evaluated a new multicomponent intervention called "7H" (7 Hypothesis). This intervention will be applied on the FA by their family doctors in the intervention group. In the control group will be developed usual cares. The main outcome is the total of visits of FA at 12 months of the follow-up. The secondary outcomes include changes happened in biopsychosocial health, satisfaction, and quality of life measurements. The investigators will assess the dependent and independents (from FA, general practitioner \[GP\] and health centres) variables at baseline, and 12 months. At baseline it will be include a random sample of 450 FA (225 for each arm), belonging to 30 family doctors of 10 health centres. It will be performed linear regression multilevel models with 4 levels (time, patient, doctor and health centre) to evaluate the effectiveness of the intervention. . Moreover will be undertaken multivariate gamma and quantile regressions to assess the cost-effectiveness and cost-utility respectively of the new intervention versus usual cares, estimating their standard errors by bootstrap calculations.
