Abstract
Purpose
Hip arthroscopy utilization continues to increase worldwide. Post-operative pain management is essential to allow appropriate rehabilitation. While multimodal analgesic protocols have been described, consensus agreement is lacking and opioid analgesia remains a mainstay of treatment. Unfortunately, the risk of persistent opioid use among opioid-naïve and non-naïve patients following hip arthroscopy remains unclear. Therefore, the purpose of this study was to identify rates of persistent post-operative opioid use, as well as to identify factors associated with persistent use.
Methods
A retrospective cohort study was conducted using linked administrative data from Ontario, Canada. Participants were adults who underwent hip arthroscopy between 2013 and 2018. Patients <18 or >60 years of age as well as those who had undergone prior hip arthroscopy were excluded. The primary exposure was whether patients had filled =2 opioid prescriptions within 1 year prior to their hip arthroscopy to define the opioid naïve and non-naïve populations. The primary outcome was persistent opioid use, defined as 2+ prescriptions filled between 9-15 months post-op. A regression analysis was performed to identify factors associated with persistent opioid usage.
Results
Of the 1,909 patients, 1,525 (79.9%) were opioid-naïve, while 384 (20.1%) had a prior history of opioid use within 1 year of surgery. 224 patients (11.7%) demonstrated persistent opioid use, with =2 prescriptions filled between 9-15 months post-op. Of those, 42 (18.8%) cases were among opioid-naïve patients, while the remaining 182 (81.2%) were among non-naïve patients. The risk of persistent post-operative use was significantly higher in those with prior opioid use (OR=31.95, 95% CI=22.15-46.09; p<0.0001). Regression analysis confirmed that pre-operative opioid use (OR=23.79, 95% CI=17.06-33.17; p<0.0001) and older age (OR=1.04, 95% CI=1.02-1.05, p<0.0001) were associated with increased risk of persistent post-operative opioid use.
Conclusion
Following hip arthroscopy, persistent opioid use is common. New persistent use was identified in 2.7% of opioid-naïve patients, compared with continued use in 47.4% of non-naïve patients. Pre-operative opioid use and older age were associated with the greater risk of persistent post-operative opioid use.
