Training and Supervision Program for Depression Management

Comprehensive Technology-Assisted Training and Supervision Program to Enhance Depression Management in Primary Care

According to the literature the management of depressive disorders at primary care level is not always consistent with guidelines. The main objective of this study is to test whether a Comprehensive Technology-Assisted Training and Supervision Program will improve depression management in Primary Health Care clinics in Santiago, Chile.

Study Overview

• Status: Completed
• Conditions: Depression
• Intervention / Treatment: Behavioral: Depression training/supervision program

Detailed Description

A cluster randomized controlled clinical trial will be conducted in four Primary Health Care (PHC) clinics in Santiago, Chile.

The sample selection of the PHC clinics will be performed in two steps. Firstly, two urban municipalities of Santiago Metropolitan Region, Chile, will be randomly selected if they work with the Faculty of Medicine of the U.Chile and have at least two PHC.Municipalities with a high Human Development Index, high percentage of immigrants and older population, and Psychiatry residents working in PHC , will be excluded.Secondly in each selected municipalities,two PHC will be randomly selected for the active and control arm.

To detect a difference of 20%, in a one-sided model, with an alpha of 5% and power of 80%, 152 depressed persons, 76 to each group, will be required for the study. A design effect of 2.42 was estimated. After applying the design effect the sample needed increased to 368 depressed persons. Considering a retention rate of approximately 85%, 434 depressed cases will be needed required for the study, hence 109 cases in each of the 4 primary health care clinics.

Analysis and presentation of the results will be in accordance with CONSORT guidelines for randomized clinical trials, with the primary comparative analysis being conducted on an intention to treat basis and due emphasis placed on confidence intervals for the between-arm comparisons.

Initially descriptive analysis to assess the balance between two groups will be conducted. The primary analysis will employ multilevel multivariable lineal regression to investigate differences in the PHQ-9 scores between groups at 3 and 6 months after randomization, adjusting for baseline outcome variable scores. Sensitivity analysis making different assumptions will be conducted to investigate the potential effects of missing data. Similar analysis will be done for the secondary outcomes measures.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Depression training/supervision program; A complex intervention, which will include: Primary Health Care team training in depression; A focus group, after training; Telephone monitoring of patients; Web-based supervision of clinicians	Behavioral: Depression training/supervision program; The intervention will be composed of: Training of Primary Health Care teams to ensure compliance to the "Clinical Guidelines of the Ministry of Health for the Treatment of Depression". Primary Health Care teams will undergo an Objective Structured Clinical Examination (OSCE) for evaluation.; After the training, a focus group between Primary Health Care teams and study researchers will be held in order to address barriers to clinical guidelines implementation.; Primary Health Care clinics' trained administrative staff will contact patients from a call-center to support treatment adherence.; Psychiatrists, using a web-based platform, will supervise the course of the program, the allocated treatments, the patients' progress, and their response to treatment.
No Intervention: Usual Care; Patients in the control group will receive all the interventions that are guaranteed for persons with depression in Chile: treatment in Primary Health Care clinics with the Primary Health Care team and referral to the regional specialized psychiatric service.
