AN e- MENTAL HEALTH COLLABORATIVE PROGRAMME TO DEPRESSION MANAGEMENT IN RURAL PRIMARY CARE IN CHILE:A PILOT CLINICAL STUDY.

In the treatment of depression, primary care team play an important role, but they are most effective when inserted into a collaborative model of disease management.

Hypotheses:Depressed patients treated in rural primary care clinics participating in a e-mental heath collaborative programme to manage depression achieve at least 20% better recovery rates in comparison with the control group three months after the baseline assessment.

Goal: to compare the effectiveness of a e-mental health collaborative programme with usual care in rural primary-care clinics.

Methodology: a clinical trial with two arms will be conducted in 13 community rural hospitals in Chile. The active group will participate in a collaborative programme between primary care teams and specialized teams, with support from an electronic platform and a call center.The control group will receive usual care, according to the Ministry of Health's Guidelines to Depression.To evaluate inclusion criteria -depressive patients aged between 18 and 70 years- and exclusion criteria -current in treatment for depression- an interview will be used that will include the Mini-International Neuropsychiatric Interview (MINI) to evaluate depression .The principal outcome will be depressive symptoms measured with the Beck Depression Inventory (BDI-I), and secondary outcome quality of life measured with the Health Survey (SF-36) at three and six months after baseline assessment.To detect a difference of 20%, in a one-sided model, with an alpha of 5% and power of 80%, would require 152 depressed persons (76 to intervention and 76 to control group).A design effect of 1.35 based on an Intraclass Coefficient Correlation (ICC) of 0,03839 and 13 clinics were considered. After applying the design effect the sample needed increased to 206 depressed persons. Considering a retention rate of approximately 85% 237 depressed cases will be needed.

A program of this kind may be useful to assist primary care teams in remote areas of the country, in order to improve treatment outcomes for depression that is currently addressed at the primary care level.
