BACKGROUND:Gallstones are a common problem in the United States with many patients suffering from symptomatic cholelithiasis (SC). Patients with SC may first present to the emergency department ED) and are often discharged for elective follow-up; however, it is unknown what system and patient factors are associated with increased risk for ED revisits. This study aimed to assess longitudinal ED utilization and cholecystectomy for patients with SC and identify patient, geographic, and hospital characteristics associated with ED revisits, specifically race/ethnicity and insurance status. METHODS:Patients discharged from the ED with SC between July 1, 2016, and December 31, 2017, were identified from California administrative databases and followed for 1 year. Emergency department revisits and cholecystectomy after discharge were examined using logistic regression, clustering standard errors by hospital. Models adjusted for patient, geographic, and hospital variables using census and hospital administrative data. RESULTS:Cohort included 34,427 patients who presented to the ED with SC and were discharged. There were 18.8% of the patients that had one or more biliary-related ED revisits within 1 year. In fully adjusted models, non-Hispanic Black patients had higher odds for any ED revisit (adjusted odds ratio 1.23; 95% confidence interval, 1.09-1.39) and for two more ED revisits (adjusted odds ratio 1.48; 95% confidence interval, 1.20-1.82). Insurance type was also associated with ED revisits. CONCLUSION:Non-Hispanic Black patients experienced higher utilization of health care resources for SC after adjusting for other patient, geographic and hospital variables. Strategies to mitigate these disparities may include the development of standardized protocols regarding the follow-up and education for SC. Implementation of such strategies can ensure equitable treatment for all patients.

BACKGROUND: Timely receipt of surgery should be available for all patients. Few studies have examined differences in the treatment of symptomatic cholelithiasis (SC), a common surgical problem, based on race/ethnicity or insurance status. This study aimed to identify differences in repeat emergency department (ED) use and wait time to cholecystectomy for SC. STUDY DESIGN: Patients discharged from the ED with SC between July 1, 2016, and December 31, 2017, were identified from California administrative databases and followed for 1 year. Repeat ED use and wait time to elective and nonelective cholecystectomy after ED discharge were examined using logistic and negative binomial regression models. RESULTS: The final cohort analyzed 13,596 patients who underwent cholecystectomy within 1 year from index ED visit for SC. In adjusted analysis, non-Hispanic Black patients had higher odds for repeat ED use for biliary-related conditions before elective surgery and experienced longer waits for cholecystectomy (across several measures of wait times) compared with non-Hispanic White patients. Similar findings were seen for Medicaid and self-pay compared with privately insured patients. For example, self-pay patients had more than double the odds of experiencing repeat ED use while waiting for elective cholecystectomy compared with privately insured patients (adjusted odds ratio 2.49, 95% CI 1.88–3.31). CONCLUSION: Patients with SC receiving cholecystectomy within 1 year from index ED visit were more likely to have repeat ED use and longer waits to surgery based on their race/ethnicity and insurance status, even after adjusting for other measures of access. We identify a vulnerable population at risk for differences in treatment for a common surgical pathology.
