The impact of opioid use on human and health care costs in surgical patients

Abstract

BackgroundPreoperative narcotic use impacts hospital cost and outcomes in surgical patients, but the underlying reasons are unclear. MethodsA single-center retrospective analysis was performed on surgical patients admitted with intestinal obstruction (2010–2014). Patients were grouped into active opioid and nonopioid user cohorts. Active opioid use was defined as having an opioid prescription overlapping the date of admission. Chronic opioid use was defined by duration of use ≥90 days. Admission or intervention due to opioid-related illness was determined through consensus decision of 2 independent, blinded clinicians. Primary end point was the effect of active opioid use on hospital resource utilization. ResultsDuring the study period, 296 patients were admitted with a primary diagnosis of intestinal obstruction. Active opioid users accounted for 55 (18.6%) of these patients, with a median length of opioid use of 164 days (interquartile range 54–344 days). Average length of use was 164 days, with the majority of active users (n = 42, 76.4%) meeting criteria for chronic use. A subgroup analysis of active users demonstrated that opioid-related conditions were responsible for 10 admissions (18.2%) and 2 readmissions (3.6%). Among active users requiring surgical intervention, 3 procedures (21.4%) were due to opioid-related illnesses. Median hospital length of stay was 2 days longer (8 vs 6 days) and hospital costs were greater ($12,241 vs $8489) among active users (P < .05 each). ConclusionActive opioid users are predisposed to avoidable admissions and interventions for opioid-related illnesses. Efforts to address opioid use in the surgical population may improve patient outcomes and health care spending.
