Abstract

ABSTRACT: The economic burden of prescription opioid abuse is substantial; however, no study has estimated the monetary burden of hospital services (emergency department [ED] and inpatient) using a single, nationally representative database. We sought to estimate total and average (adjusted for demographic and clinical factors) charges billed for opioid abuse–related events, and magnitude of difference in charges between ED visits resulting in inpatient admission to the same hospital and treat-and-release ED visits in the United States. We used the 2006, 2007, and 2008 files of the Healthcare Cost and Utilization Project's Nationwide Emergency Departments Sample (HCUP-NEDS) to identify events and charges assigned opioid abuse, dependence, or poisoning ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) diagnosis codes (304.0X, 304.7X, 305.5X, 965.00, 965.02, 965.09). Using methods to account for the complex sampling design of the NEDS and a log-linked gamma regression model, we estimated national total and mean charges (in 2010 USD). Total charges were $9.8, $9.6, and $9.5 billion for 2006, 2007, and 2008, respectively. Medicaid-covered events had the highest total charges ($3 billion), followed by events covered by Medicare ($2 billion) for each year. The national estimate of adjusted, mean, per-event charges, was $18, 891 (95% confidence interval [CI] = $18, 167–$19, 616). Compared with events covered by private insurance, mean charges for Medicare- and Medicaid-covered events were higher ( t = 28.14, P < .001; t = 6.42, P < .001, respectively), whereas self-paid events had significantly lower charges ( t = −11.14, P < .001). ED visits resulting in subsequent inpatient admission had approximately 6 times higher charges than treat-and-release visits. This study provides estimates of differences in hospital costs of opioid abuse by insurance status, resulting in a better understanding of the economic burden of opioid abuse on the health care system.
