Using linked administrative databases, we estimated the prevalence of opioid prescriptions with &gt;7\u2009days' supply, \u226590 morphine milligram equivalents (MME)\/day or long\u2010acting opioids. We assessed the association of care setting and specialty with these outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 124,515 patients, 36,716 (29.5%) were opioid\u2010naive. The median opioid supply duration was 3\u2009days (IQR 2\u20135), the median dose was 50 MME\/day (IQR 30\u201375). Prescriptions for &gt;7\u2009days, \u226590\u2009MME\/day or involving long\u2010acting opioids were filled by 10.9%, 20.2% and 0.7% of the patients, respectively. Hydromorphone (50%) and codeine (26.4%) were the most filled opioids. The emergency care setting had double the odds of filling &gt;7\u2009days' supply (OR 2.13, 95% CI 1.99\u20132.28), and 69% lower chance of filling \u226590\u2009MME\/day (OR 0.31, 95% CI 0.29\u20130.33) than surgical care. In the surgical care setting, there was significant variation across medical specialties. Otolaryngology was associated with a higher chance of prescribing &gt;7\u2009days' opioid supply than general surgery (OR 4.89, 95% CI 3.86\u20136.20). Orthopaedic surgery had a higher likelihood of \u226590\u2009MME\/day prescriptions (OR 2.92, 95% CI 2.58\u20133.30) than general surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion and Conclusions<\/jats:title><jats:p>Opioid prescribing patterns vary significantly by setting and specialty in Nova Scotia, Canada.
