Purpose:
Elective laparoscopic cholecystectomy is increasingly being conducted as a day-case procedure. However, some patients planned for day-case surgery stay in hospital for at least one night. The aim of this study was to identify factors associated with conversion from planned day-case to in-patient management for elective laparoscopic cholecystectomy.
Methods:
This was an exploratory retrospective analysis of observational data from the Hospital Episode Statistics dataset for England. All patients aged ≥ 17 years undergoing a planned elective day-case laparoscopic cholecystectomy between 1st April 2017 and 31st March 2024 were identified. The exposure of interest was discharge on the day of admission (day-case) or requiring overnight stay. For reporting, providers were aggregated to an Integrated Care Board (ICB) level.
Results:
A total of 286,754 elective LCs planned as day-case were identified over the seven-year study period. Of these, 74,957 (26.1%) stayed in hospital for at least one night and were classed as day-case to in-patient stay conversions. In multilevel, multivariable modelling, conversion to in-patient stay was associated with great age (odds ratio (OR) 2.54 for 17-29 vs ≥ 70 years, p < 0.001), male sex (OR = 1.11, p < 0.001), deprivation (OR 1.14, first vs fifth quintile, p < 0.001), open surgery (46.93, p < 0.001), and low annual surgeon volume (OR 1.73, < 10 vs ≥ 80 LCs per year, p < 0.001). Comorbidities and post-procedural complications were also strongly associated with conversion. Across the 42 ICBs in England, model-adjusted conversion rates varied from 14.5% to 39.0%, 18 (42.9%) ICBs had conversion rates above the 99.8% control limit.
Conclusions:
Conversion from day-case to in-patient stay was associated with increasing age, male sex, deprivation, open surgery, low surgeon volume, comorbidity and post-procedural complication. Our findings will help surgical team identify patients suitable for day-case laparoscopic cholecystectomy.
