Postoperative Discharge Scoring Criteria After Outpatient Anesthesia: A Review of the Literature

Abstract

Purpose: The aim of this review was to explore the existing literature on discharge criteria, tools and strategies used in the postanesthesia care unit (PACU) after ambulatory surgery and to identify the essential components of an effective and feasible scoring system based on applicable criteria for the three phases of anesthesia recovery to assess patient discharge after outpatient anesthesia.

Design: A review of the literature.

Methods: In this study, a review of sixteen articles was conducted to analyze the affecting factors, evaluation tools, and the current research status of patients discharge after outpatient anesthesia.

Findings: The main factors affecting the discharge after diagnostic or therapeutic procedures under outpatient anesthesia were hospital management, medical treatment and patients themselves. Physiological systems-based discharge assessment had several advantages over traditional time-based discharge assessment. The Aldrete scoring scale was often used for patients in the first stage of anesthesia recovery to leave the PACU, and the Chung's scoring scale was often used to evaluate patients in the second stage of recovery until they leave the hospital. These two scales were often used in combination for outpatient anesthesia. The Fast-tracking assessment tool was used in patients who directly returned to the ward or discharge of patients after ambulatory surgery. There is currently no uniform standard or tool for assessing patients discharge after diagnostic or therapeutic procedures under the outpatient anesthesia.

Conclusions: Optimal care under anesthesia should allow the patient to recover from anesthesia smoothly and quickly and leave the hospital safely. When the patients can safely leave the hospital after outpatient anesthesia is still a problem that needs to be solved in the nursing field. Various existing scoring systems have their historical advancements, but we need to formulate more in line with the current status of postoperative patients discharge standards.
