Background : Despite increased use of ambulatory gastrointestinal endoscopy, few data exist regarding patient
recovery patterns and home-readiness.
Objective : The authors prospectively identified the pattern of home-readiness, the persistent symptoms after
procedure and the factors that delay discharge after home-readiness criteria are satisfied.
Materials and Methods : Three hundred and sixty nine patients were scored by the investigator using the
Modified Post-Anesthetic Discharge Scoring System (PADSS) every 30 min, commencing 30 min after procedure,
until the PADSS score was > 9. The same investigator telephoned each patient 24 hr after discharge to
administer a standardized questionnaire so that postoperative symptoms could be identified.
Results : The number of patients who satisfied the PADSS home-readiness criteria was 81.6%, 97.9%, and
100% at 30, 60, and 90 min, respectively. All patients were promptly discharged before two hours. After home-
readiness criteria were satisfied, 36% of patients had delayed discharge because of the unavailability of
immediate escorts or other non-medical reasons. No patient had persistent symptoms and all patients could
achieve a PADSS score > 9 three hours after anesthesia. The patients undergoing shorter endoscopic procedures,
such as EGD or dilated esophagus were discharged faster than patients undergoing colonoscopy or duodenal
stent. The 24 hr postoperative symptoms were mainly sore throat, pain, weakness, and abdominal distension.
There was no incidence of unanticipated admission.
Conclusion : Periodic objective evaluation of home-readiness revealed that the majority of patients would
achieve a satisfactory score on or before 1 hr after procedure. The time to home-readiness by objective
evaluation correlated with the type of procedure. Most delays after satisfactory home-readiness scores were
reached, were due to non-medical reasons.
