ABSTRACT
BACKGROUND:
Optimal control for the management of the length of stay in the postanesthesia care unit (PACU) following general anesthesia in adults is an important strategy for surgical patients' care. A model to predict the results of the PACU stays could be used to improve the utilization of the PACU and resources of the operating room through a more efficient arrangement. The purpose of this study was to evaluate the performance of the decision tree based analysis using clinical sets of data from adult patients undergoing general anesthesia.METHODS:
The decision tree was trained with 351 clinical sets (86% in 409 data sets) using a Chi-squared automatic interaction detection (CHAID) algorithm and validated through independent testing of 58 cases (14%). Twenty-two independent variables were used to find determinant variables and to predict categorical dependent values (lengths of stay in the PACU).RESULTS:
The decision tree based analysis correctly predicted in 68% of real situations and identified influencing variables as intubation state, complication in the PACU, and intraoperative transfusion.CONCLUSIONS:
We concluded that the decision tree based analysis could provide a useful predictive and classifying model for the optimization of limited resources of the PACU. The decision tree based analysis is an alternative way of classifying, and a predicting method for developing a model for lengths of stay in the PACU with easy interpretation and clear graphical displays of the structure of variables.
