Abstract
Data sources such as medical insurance claims are increasingly used in outcomes research. In this report, we present opportunities and limitations associated with the use of such data for outcomes research in the area of depression. The purpose of this report is to illustrate the use of administrative claims data in conducting research in the area of depression. Information in this report is intended to be helpful to both experienced health services researchers and to those who may be new to the field of either outcomes research or mental health research. FORMAT: This report covers measurement of outcomes, possible data sources, episode construction, and statistical methodologies that are appropriate when conducting depression research using claims data. Through examples and references, issues to be considered in each of these areas are examined and recommendations are made. Strengths and limitations of claims data will also be pointed out. The use of claims data to conduct outcomes research in depression should be carried out responsibly. Limitations with using claims data to identify patients with depression must be acknowledged and appropriate methodologies should be used. Still, these data sources provide a rich opportunity to conduct outcomes research in depression, and much can be learned using administrative claims data.
