Background: Acute pain is common following surgery, with opioids frequently employed in its management. Studies indicate that commencing an opioid during a hospital admission increases the likelihood of long-term use. This study aimed to identify the prevalence of opioid persistence amongst opioid-naïve patients following surgery as well as the indication for use.

Methods: A retrospective review of patients who underwent a surgical procedure at the Royal Hobart Hospital, Tasmania, Australia, between August and September 2016 was undertaken. Patients were linked to the Tasmanian real-time prescription monitoring database to ascertain if they were subsequently dispensed a Schedule 8 opioid (morphine, codeine oxycodone, buprenorphine, hydromorphone, fentanyl, methadone, or tapentadol) and the indication for use.

Results: Of the 3275 hospital admissions, 1015 opioid-naïve patients were eligible for inclusion. Schedule 8 opioids were dispensed at or within 2 days of discharge in 41.7% of admissions. Thirty-nine (3.9%) patients received prescribed opioids 2-months post-discharge; 1.8% of the patients were approved by State Health to be prescribed Schedule 8 opioids regularly for a chronic condition at 6 months, and 1.3% received infrequent or one-off prescriptions for Schedule 8 opioids at 6 months. Thirteen (1.3%) patients continued Schedule 8 opioids for at least 6 months following their surgery, with the indication for treatment either related to the surgery or the condition which surgery was sought for.

Conclusion: This study found that there was a low rate of Schedule 8 opioid persistence following surgery, indicating post-surgical pain is not a significant driver for persistent opioid use.
