Population-based cohort study of outcomes following cholecystectomy for benign gallbladder diseases
Insights
Readmissions and complications after gallbladder surgery are common. Patient factors like fitness grade and prior admissions, not hospital features, predict these outcomes, guiding better patient care.
Area of Science:
- Surgical outcomes research
- Gastrointestinal surgery
- Health services research
Background:
- Benign gallbladder disease management is crucial.
- Understanding readmission and complication factors post-cholecystectomy is essential for improving patient outcomes.
Purpose of the Study:
- To describe benign gallbladder disease management.
- To identify patient and hospital factors linked to 30-day readmissions and complications after cholecystectomy.
Main Methods:
- Prospective population-based cohort study.
- Analysis of 8909 patients undergoing cholecystectomy across 167 UK and Irish hospitals.
- Multilevel, multivariable logistic regression modeling to identify predictors of readmissions and complications.
Main Results:
- 30-day readmission rate was 7.1%; complication rate was 10.8%.
- Increasing American Society of Anesthesiologists (ASA) fitness grade, longer surgery duration, and prior emergency admissions for gallbladder disease independently predicted readmissions and complications.
- No hospital-specific characteristics were associated with readmissions or complications.
Conclusions:
- Readmissions and complications following cholecystectomy are frequent.
- Patient-related factors, including ASA grade and history of previous admissions, are key predictors.
- Focusing on patient characteristics can help mitigate post-cholecystectomy adverse events.
Background:
The aim was to describe the management of benign gallbladder disease and identify characteristics associated with all-cause 30-day readmissions and complications in a prospective population-based cohort.
Methods:
Data were collected on consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing all-cause 30-day readmissions and complications were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results:
Data were collected on 8909 patients undergoing cholecystectomy from 167 hospitals. Some 1451 cholecystectomies (16·3 per cent) were performed as an emergency, 4165 (46·8 per cent) as elective operations, and 3293 patients (37·0 per cent) had had at least one previous emergency admission, but had surgery on a delayed basis. The readmission and complication rates at 30 days were 7·1 per cent (633 of 8909) and 10·8 per cent (962 of 8909) respectively. Both readmissions and complications were independently associated with increasing ASA fitness grade, duration of surgery, and increasing numbers of emergency admissions with gallbladder disease before cholecystectomy. No identifiable hospital characteristics were linked to readmissions and complications.
Conclusion:
Readmissions and complications following cholecystectomy are common and associated with patient and disease characteristics.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
