Predictors of 30 Day Readmission Following Percutaneous Cholecystostomy.

BACKGROUND

High-risk patients undergoing cholecystectomy may experience increased morbidity and mortality. Percutaneous cholecystostomy (PC) has been utilized as a treatment option for acute cholecystitis in this cohort. Little is known about risk factors for readmission following PC.

MATERIALS AND

METHODS

Patients who had PC from 2013 to 2014 were identified from the National Readmission Database by the Healthcare Cost and Utilization Project. A 30-d readmission was defined as a subsequent admission within 30 d following the first admission discharge date. Multivariate logistic regression models using stepwise selection were employed to select significant predictive variables for subsequent readmission.

RESULTS

Three thousand three hundred sixty-eight patients were identified with 698 (20.7%) readmissions during the study period. Of the readmitted patients, 79 (2.35%) had two readmissions and six patients (0.19%) had three or more readmissions within 30 d of their index procedure. In addition, alcohol use (odds ratios [OR] 1.58, confidence intervals [CI] 1.10-2.29), uncomplicated diabetes (OR 1.21, CI 1.00-1.47), congestive heart failure (OR 1.28, CI 1.03-2.44), depression (OR 1.42, CI 1.08-1.86), and metastatic cancer (OR 1.65, CI 1.11-2.46) were significantly correlated with risk for readmission. Readmitted patients had longer hospital stays (OR 1.38 CI 1.09-1.74, length of stay >8 d).

CONCLUSIONS

A significant proportion of patients are readmitted within 30 d following PC. These patients may benefit from increase care coordination starting at their index admission. Studies are needed to determine patient selection for upfront cholecystectomy.
