Abstract

Introduction: Cyclical vomiting syndrome (CVS) carries a significant financial burden on the U.S. healthcare system due to the recurrent emergency department visits and inpatient hospitalizations. We aimed to update the literature on the predictors of hospital utilization and readmission among individuals admitted with CVS. Methods: This is a retrospective nationwide study of patients hospitalized with a primary diagnosis of CVS. Using weighted data from the National Inpatient Sample (NIS) and the National Readmission Database (NRD), we conducted a multivariate regression analysis to assess predictors of length of stay (LOS), and 30-day readmission. Results: Primary admissions for CVS totaled 35,055 in the NIS, and 31,240 in the NRD. 2012 patients (6.4%) were readmitted within 30 days. On multivariate regression, cannabis use was associated with reduced LOS (adjusted Mean Difference (aMD) = −0.53 days, 95% CI: −0.68 to −0.38), and 30-day readmissions (adjusted Hazard Ratio (aHR) = 0.63, 95% CI: 0.54–0.73). Discussion: Cannabis use among CVS admissions was associated with reduced LOS and 30-day readmissions; these results could be in fact driven by Cannabis Hyperemesis Syndrome (CHS)-related hospitalizations and the effect of cannabis cessation on decreased symptomatology. ICD-10 coding for CHS should be transitioned to specific codes to improve the differentiation between CVS and CHS-related hospitalizations.
