Standardizing process in acute biliary disease.

INTRODUCTION

The perioperative management of biliary disease (BD) is variable across institutions with suboptimal outcomes for patients and health care systems. This results in inefficient utilization of limited resources. The aim of the current study was to identify modifiable factors impacting patients' time to theater, intraoperative time, and time to discharge as the constituents of length of stay to guide creation of a perioperative management protocol to address this variability.

METHODS

Data were prospectively captured at Christchurch Hospital for all adult patients presenting for cholecystectomy between May 2015 and May 2022. Pre, post, and intraoperative factors were assessed for their impact on time to theater, operative time, and postoperative hours to discharge.

RESULTS

Four thousand five hundred seventy-seven patients underwent cholecystectomy during the study period, of which 2807 (61%) were acute presentations and made up the cohort for analysis. Time to theater was significantly impacted by preoperative imaging type, while operative grade and the procedure type had the most clinically significant impact on operative time. Postoperatively time to discharge was significantly impacted by drain placement.

CONCLUSIONS

Standardizing management of BD would likely result in significant savings for the health care system and improved outcomes for patients. The data seen here evidence the importance of appropriate imaging selection, intraoperative difficulty operative grade identification, and low suction drain selection. These data have been incorporated in a perioperative management protocol as standardization of care across the patient workflow in BD is a sensible approach for ensuring optimal use of scarce resources.
