Productivity Loss and Indirect Burden of Cyclic Vomiting Syndrome in the United States

Abstract

Background and Aims: To quantify the indirect burden of cyclic vomiting syndrome (CVS), we assessed work-related productivity loss in patients with CVS and caregivers using large-sized databases in the United States. Methods: Patients aged 18-64 years with full-time employment in MarketScan Commercial and Health and Productivity Management Databases were selected if they had ≥1 inpatient or ≥2 outpatient claims for CVS between 2008 and 2018 and continuous enrollment of ≥6 months before and ≥3 months after the initial CVS diagnosis. CVS caregivers were adults with full-time employment and also having dependent(s) with CVS. Propensity scores via multivariable regressions were used to match patients with CVS and their caregivers to non-CVS controls. Productivity loss was assessed by short-term disability (STD) and absenteeism (ABS) days, and the associated costs were also calculated. Differences between the matched cohorts were regarded as the burden attributable to CVS. Results: < .001). Conclusion: CVS is associated with higher productivity loss due to STD/ABS and, therefore, greater indirect costs for patients and caregivers. Further research is needed to assess the full societal burden of CVS. More effective interventions may reduce the disease burden.
