The Use of Determinants of Length of Stay in the Post-anesthesia Care Unit (PACU) at the Philippine General Hospital among Postoperative Patients who Underwent Elective Surgeries to Create a Predictive Model for PACU Length of Stay

Abstract

Background. The aims of this study were to determine the average length of stay in the Post-anesthesia CareUnit (PACU LOS) in the Philippine General Hospital (PGH) and to create a model that will predict the PACU LOSbased on the factors that significantly affect the LOS. Determination and prediction of PACU LOS is essential inresource utilization, and in cost containment and reduction. Addressing the modifiable variables that affect thePACU LOS may lead to an improvement in the LOS of patients in the PACU and, consequently, to better recoveryroom staffing and a reduced cost for the patients and the hospital.
 Methods. A prospective chart review of 400 postoperative patients admitted in the PGH PACU was done. Summarystatistics were presented. Using the set of variables found to be significant, a regression model was formulatedto estimate the PACU LOS.
 Results. The mean PACU LOS was 4.59 hours. There were significant differences in the mean PACU LOS basedon the occurrence of complications. There were also significant differences in the median PACU LOS based onthe type and duration of surgery, anesthetic technique, and duration of anesthesia. The multiple linear regressionmodel that best predicted PACU LOS included ASA-PS classification, type of surgery, duration of surgery, anesthetictechnique, and occurrence of intraoperative or postoperative complications.
 Conclusions. The mean PACU LOS of the Philippine Genera Hospital is higher than that of published data. Thefactors included in the model that best predicts PACU LOS may be studied to improve the PACU LOS.

Incidence and Factors Associated With Post-anesthesia Care Unit Complications at St. Paul’s Hospital, Ethiopia. Observational Study

“…The length of stay in PACU greater than 4 hours (AOR=4.538;95% CI (2.089 -9.857) were strongly correlated with the incidence of PACU complication, our study also observed that patients who encountered PACU complications signi cantly required a prolonged duration of stay than initially planned compared to patients without complications (9,22).…”

“…On the other hand, the study done in the Philippines revealed that duration of surgery, the occurrence of intraoperative complications, and postoperative complications were identi ed as signi cant predictors for the length of stay at PACU (22).…”

“…10 On the other hand, the study done in the Philippines revealed that duration of surgery, the occurrence of intraoperative complications, and postoperative complications were identified as significant predictors for the length of stay at PACU. 26 Despite the magnitude of the problem in daily clinical activity, there has been very little or no research examining the incidence and factors associated with PACU complications in sub-Saharan countries including Ethiopia. The main objective of this study is to evaluate the incidence of complications and associated factors among surgical patients admitted in limited-resource settings of the PACU.…”
