Cascade iatrogenesis is defined as a related sequence of adverse events that are triggered by an initial medical intervention. In an attempt to determine whether such a phenomenon is be associated with the quality of care provided, physician reviewers identified iatrogenic cascades and the rated quality of care given to a sample of long-stay teaching hospital patients. The care was rated with a structured implicit review instrument. Cascade iatrogenesis was found to occur most frequently among the oldest patients, the most functionally impaired, and those with a high severity of illness on admission. Closer examination of these findings suggests that there is significant potential for improving physicians' initial functional and diagnostic assessment skills when treating frail elderly patients.
