Abstract

Background

An understanding of the relationship between patient factors and healthcare resource utilization represents a major point of interest for optimizing clinical care and overall net savings, yet maintaining financial margins for provider revenues. This study aims to review resource utilization after cholecystectomy in order to characterize patient factors associated with increased postoperative ED visits and 30-day readmissions.

Methods

A total of 53,632 open and laparoscopic cholecystectomies were reviewed from July 2009 to December 2010 in a large private payer claims database. ICD-9 and CPT codes were available for each event, as well as basic demographics. Data regarding 30-day postoperative resource utilization metrics (emergency department visits and inpatient hospitalizations) were analyzed and stratified by key patient comorbidities. Differences between subgroups were evaluated with univariate and multivariable methods.

Results

Of the 53,632 patients studied, 71.2 % (38,171) were female and 28.8 % (15,461) male. Resource utilization within 30 days of surgery included: 6.6 % (3538) of patients with an ED visit and 7.7 % (4103) with an inpatient hospitalization. The most common comorbidities in the study population were: hypertension, hyperlipidemia, GERD/hiatal hernia, and diabetes mellitus. Patients with heart failure, cirrhosis, and a history of MI or acute ischemic heart disease all had a significant association with postoperative ED visit and the highest likelihood of inpatient hospitalization. Angina, diabetes, and hypertension similarly increased both ED utilization and inpatient readmissions to a lesser but still significant extent. Although patients with GERD/hiatal hernia and sleep apnea had a significant association with ED use, they did not have an increased likelihood of readmission.

Conclusions

Patient comorbidity indexing plays a major role in clinical risk stratification and resource utilization for cholecystectomy. These factors should be considered in bundled reimbursement packages and in the creation of preventive postoperative ambulatory strategies given their role in determining potential resource utilization in the postoperative setting.
