Antidepressant treatment in children and adolescents: bridging the gap between efficacy and effectiveness.

This review of antidepressant treatments in children and adolescents emphasizes the gap between efficacy data derived from randomized clinical trials (RCTs) and the limited effectiveness data from community-based practices. Part one is a brief review of data from randomized, double-blind clinical trials to assess the evidence base for the major approved indications for antidepressants in youths. Part two reviews information gaps in the evidence from RCTs. Part three discusses nonexperimental evidence of the use of antidepressants, including surveys of prescription sales, physician surveys, and population-based data. Part four presents a comprehensive model for assessing the use of antidepressants in youths in the community. The model aims to answer a range of public health-oriented questions and is intended to improve treating physicians' and clinical care providers' ability to manage medications for optimal patient benefit. Suggestions are made for engaging health service providers, health insurers, academicians, advocates, and the government in building the necessary infrastructure to make effectiveness as vital as efficacy to the model of drug therapy evaluation.
