Data_Sheet_1_Association between opioid prescription profiles and adverse health outcomes in opioid users referred for sleep disorder assessment: a secondary analysis of health administrative data.pdf

BackgroundInformation is needed to guide safe opioid prescribing in adults referred for a sleep disorder assessment. Previous studies have shown that individuals referred for a sleep disorder assessment have a higher likelihood of long-acting opioids and higher opioid dosages prescription than the general population, suggesting that these individuals are more at risk for opioid-related adverse health consequences.
MethodsWe included all adults who underwent a diagnostic sleep study (index date) in Ontario, Canada, between 2013 and 2016 (n = 300,663) and filled an opioid prescription overlapping the index date (n = 15,713). Through provincial health administrative databases, individuals were followed over time to assess the association between opioid use characteristics and 1-year all-cause mortality, hospitalizations and emergency department (ED) visits, and opioid-related hospitalizations and ED visits within extended follow-up to 2018.
ResultsControlling for covariates, chronic opioid use (vs. not) was significantly associated with increased hazards of all-cause mortality [adjusted hazard ratio(aHR): 1.84; 95% confidence interval (CI): 1.12–3.02], hospitalization (aHR: 1.14; 95% CI: 1.02–1.28) and ED visit (aHR: 1.09; 95% CI: 1.01–1.17). A higher opioid dosage [morphine equivalent daily dose (MED) >90 vs. ≤ 90 mg/day] was significantly associated with increased hazards of all-cause or opioid-related hospitalization (aHR: 1.13; 95% CI: 1.02–1.26 and aHR: 2.27; 95% CI: 1.53–3.37, respectively). Morphine or hydromorphone prescription (vs. oxycodone) was significantly associated with an increased hazard of all-cause hospitalization (aHR: 1.30; 1.07–1.59 and aHR: 1.43; 95% CI: 1.20–1.70, respectively). Hydromorphone or fentanyl prescription (vs. oxycodone) was significantly associated with an increased hazard of opioid-related ED visit and/or hospitalization (aHR: 2.28, 95% CI: 1.16–4.47 and aHR: 2.47, 95% CI: 1.16–5.26, respectively).
ConclusionFindings from this retrospective study may inform the safe prescribing of opioids in adults referred for a sleep disorder assessment.
