Basilico M, et al. - A sum of 17,961 adult opiate-naive cases treated for a surgical musculoskeletal injury were analyzed to examine if initial opiate type prescribed to postoperative, opiate-naive orthopedic trauma patients was correlated with extended opioid use (opioid prescribing beyond 90 days after injury). They observed a higher probability of prolonged use for cases discharged on hydromorphone or morphine vs hydrocodone. The only opioid quantity was predictive of prolonged use when adjusted for discharge morphine milligram equivalents. They elaborated that persistent opiate use was correlated with discharge opioid quantity, not the opioid type.
