Insights
Performing an additional surgical procedure during cholecystectomy increases the risk of 30-day hospital readmission. This finding is crucial for improving patient outcomes and reducing healthcare costs associated with cholecystectomy readmissions.
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Surgical Outcomes Research
- Health Services Research
Background:
- Hospital readmissions after cholecystectomy pose a significant burden on healthcare systems.
- Identifying risk factors for 30-day readmissions is essential for targeted interventions and improved patient care.
Purpose of the Study:
- To assess risk factors associated with 30-day hospital readmissions following cholecystectomy.
- To identify specific surgical and patient-related factors influencing readmission rates.
Main Methods:
- A case-control study was conducted using data from UC-Christus, Santiago, Chile (2015-2019).
- Patients undergoing cholecystectomy were analyzed, with readmitted patients compared to a control group.
- Univariate and multivariate analyses were employed to determine significant risk factors.
Main Results:
- The study included 4866 cholecystectomies, with a 1.6% (79 patients) 30-day readmission rate.
- Univariate analysis identified solid tumors, high bilirubin/alkaline phosphatase, emergency admission, choledocholithiasis, additional procedures, and post-operative complications as risk factors.
- Multivariate analysis confirmed that performing an additional surgical procedure during cholecystectomy was a statistically significant risk factor (OR = 4.24).
Conclusions:
- Performing an additional surgical procedure during cholecystectomy is a significant risk factor for 30-day hospital readmission.
- These findings highlight the importance of optimizing surgical strategies to minimize readmissions and improve patient outcomes.
Objective:
The aim of this study was to assess the risk factors associated with 30-day hospital readmissions after a cholecystectomy.
Methods:
We conducted a case-control study, with data obtained from UC-Christus from Santiago, Chile. All patients who underwent a cholecystectomy between January 2015 and December 2019 were included in the study. We identified all patients readmitted after a cholecystectomy and compared them with a randomized control group. Univariate and multivariate analyses were conducted to identify risk factors.
Results:
Of the 4866 cholecystectomies performed between 2015 and 2019, 79 patients presented 30-day hospital readmission after the surgical procedure (1.6%). We identified as risk factors for readmission in the univariate analysis the presence of a solid tumor at the moment of cholecystectomy (OR = 7.58), high pre-operative direct bilirubin (OR = 2.52), high pre-operative alkaline phosphatase (OR = 3.25), emergency admission (OR = 2.04), choledocholithiasis on admission (OR = 4.34), additional surgical procedure during the cholecystectomy (OR = 4.12), and post-operative complications. In the multivariate analysis, the performance of an additional surgical procedure during cholecystectomy was statistically significant (OR = 4.24).
Conclusion:
Performing an additional surgical procedure during cholecystectomy was identified as a risk factor associated with 30-day hospital readmission.
