Opioid overdoses are a growing cause of mortality in the United States. Medical prescriptions for opioids are a risk factor for overdose. This observation raises concerns that patients may seek multiple opioid prescriptions, possibly increasing their overdose risk. One route for obtaining those prescriptions is visiting the emergency department (ED) for pain-related complaints. Here, two hypotheses related to prescription seeking and overdoses are tested. (1) Overdose patients have a larger number of prior ED visits than matched controls. (2) Overdose patients have distinct patterns of pain-related complaints compared to matched controls.
Objective:
Identifying text features of emergency department visits associated with risk of future drug overdose.
