[Causes of 72-hour return visits to hospital emergency departments].

OBJECTIVES

The return-visit rate has been suggested as a measure of emergency department quality of care. We aimed to identify the reasons for emergency revisits and the percentage of returns related to problems with quality of care in the previous visit.

MATERIAL AND METHODS

Cross-sectional observational study of clinical records for a random sample of unscheduled returns within 72 hours of discharge from the emergency departments of 3 hospitals attending a population of nearly 3 million in the Spanish province of Malaga. The records were reviewed by 2 data collectors, who assigned a reason for revisits according to a standardized classification.

RESULTS

A sample of 1075 emergency revisits were reviewed; 895 met the inclusion criteria. The most common reasons for revisits were the persistence or progression of disease (48.8%), an unrelated new problem (9.3%), and referral from a hospital that did not have the required specialized service (8.6%). Reasons attributable to the patient accounted for 14.5% of the revisits; 15.2% were attributable to health care staff errors, 9.2% to system organization, and 61.1% to the disease process.

CONCLUSION

Most emergency department revisits are related to the progression of the disease that led to the first visit. Only a small percentage can be linked to diagnostic or treatment errors in the previous visit.
