Discharges against medical advice and 30-day healthcare costs: an analysis of commercially insured adults

Abstract

Aim: Prior literature detailing the consequences of a discharge against medical advice (DAMA) has not focused on costs. We examine costs following a DAMA. Materials & methods: This retrospective cohort study utilized the IQVIA PharMetrics® Plus database to identify adults hospitalized during 2007–2015. We compared 30-day postdischarge healthcare costs between matched DAMA and routinely discharged groups. Results: Thirty-day healthcare costs for the DAMA group were US$1078 (95% CI: US$434–1730) higher, driven by inpatient readmissions (US$979; 95% CI: US$415–1543) and emergency department visits (US$79; 95% CI: US$56–102). Costs due to prescription drug fills were lower in the DAMA group. Conclusion: A DAMA was associated with higher 30-day postdischarge healthcare costs compared with routine discharges.
