The aim of this study was to evaluate the association of patient familiarity and perceptions regarding efficacy and risks with opioid medication use for OA.Methods A total of 362 adults with knee and/or hip OA were surveyed in this cross-sectional study. Patients’ familiarity with and perceptions of benefits/risks of opioid medications were measured to evaluate potential associations with the utilization of opioid medications for OA within the last 6 months. Logistic regression models were adjusted for sociodemographic and clinical variables.Results In this sample, 28.7% (100/349) reported use of an opioid medication for OA-related symptoms in the last 6 months. Those who were on an opioid medication, compared to those who were not, were younger (mean age 62.5 vs 64.8 yrs), were more likely to have a high school education or lower (48.0% vs 35.3%), and had higher mean depression (Patient Health Questionnaire [PHQ]-8 7.2 vs 4.9) and OA-related pain (Western Ontario and McMaster Universities Arthritis Index [WOMAC] 54.8 vs 46.8) scores. After adjustment for sociodemographic and clinical variables, the following were associated with opioid medication use: higher perception of medication benefit (OR 1.68, 95% CI 1.18–2.41), lower perception of medication risk (OR 0.67, 95% CI 0.51–0.88), and having family or friends who received the medication for OA (OR 3.88, 95% CI 1.88–8.02).Conclusion Among adults with knee/hip OA, opioid use was associated with being familiar with the treatment, as well as believing that the medication was beneficial and low-risk.
