|Summary of Findings
|Of 96 Evidence-based Practice Center evidence reports published between December 1998 and April 2004, 71 addressed health care interventions associated with potential harms. Of these, 11 did not assess harms. Two of the 11 evaluated surgical interventions, and the other 9 evaluated pharmacologic interventions or approaches to diagnostic testing and disease management. Of the 60 remaining EPC reports, 34 included observational studies of adverse events. Quality of observational studies is difficult to uniformly assess due to differences in study design for harms data and data from these studies is often inappropriately combined.
