Objective: To develop a survey instrument to identify adult sickle cell disease (SCD) patients on chronic opioid therapy who are at-risk for opioid abuse. Design: Prospective survey and interview.Setting: Adult SCD clinic in a large urban teaching facility.Patients/participants: Convenience sampling of adult patients presenting to the sickle cell clinic.Interventions: None.Main outcome: Primary outcome was “at-risk for opioid misuse,” defined as at least 3/8 “yes” answers (a positive composite score) on the Prescription Opioid Misuse Index (POMI) questionnaire. Secondary outcome was DSM-IV criteria for substance abuse using the DSM IV Diagnostic Interview Schedule.Results: Of the 99 patients who completed the POMI, the mean age was 36 years; 58.6 percent were female, 48 percent were hemoglobin SS (47/99), and 26 percent were SC (26/99). Twenty-four percent (24/99) were identified as at-risk for opioid misuse using the POMI. There were no differences in demographic, SCD genotype, or socioeconomic variables for at-risk versus not-at-risk patients.Conclusion: Twenty-four percent of unselected adult SCD patients on opioids were identified as at-risk for opioid misuse using a quick survey. This may represent as much as 2.5-7 times the national misuse rate. This group of patients may benefit from additional diagnostic and therapeutic interventions to help understand and manage their opioid usage.
