Second, the use of HCFA data sets is limited by several vexing problems that will hinder effectiveness research on the Medicare population, at least for AMI. These limitations include the variability in diagnostic coding of AMI, the lack of relevant ambulatory data both before and after hospitalization, and the inadequacy of coding for common interventions and new interventions as they are put into practice.

In some cases—when conclusions cannot be drawn from, say, the HCFA a~ninistrative data or effectiveness research projects alone effectiveness analyses may indicate the need for specific RCI~s, and the committee judged that this would be a valuable input into improving health care delivery and health services research over the long run. Analysis of observational natural experiments based on risk stratification of patients by clinicians must include adjustment for risk of patients selected to receive different treatments, including adjustments related to comorbidity.
