Implementation of a Standardized Discharge Time-out Process to Reduce Prescribing Errors at Discharge

Background: To reduce prescribing errors occurring on discharge from the hospital, a standardized discharge time-out process was implemented on a general medicine service at Wake Forest Baptist Medical Center. In the time-out process, the multidisciplinary care team reviewed the patient's medical records together to determine the optimal discharge medication regimen. This regimen was recorded on a time-out form and then was used to develop the patient's discharge documents.

Objective: To evaluate the impact of a standardized discharge time-out process on prescribing errors that occur as patients are discharged from a general medicine service.

Methods: The medical records of all patients discharged from a general medicine service during 60-day periods before ("pre-group") and after ("post-group") implementation of a standardized discharge time-out process were retrospectively reviewed by an internal medicine physician to determine the presence of discharge prescribing errors.

Results: There were 142 and 124 evaluable patients in the pre- and post-groups, respectively. Compliance with the time-out process was 93% in the post-group. At least 1 prescribing error was detected in 49 (34.5%) of the discharges in the pre-group and 17 (13%) of the discharges in the post-group (P < .0001). All of the errors noted in the post-group occurred in discharges in which a clinical pharmacist was not involved.

Conclusions: A multidisciplinary, standardized discharge time-out process was associated with a dramatic reduction in prescribing errors when patients were discharged from a general medicine service. The time-out process is one strategy to improve patient safety at hospital discharge.
