Introduction/Purpose:
Total ankle arthroplasty (TAA) is an increasingly-utilized treatment for ankle arthritis, and opioids are commonly used as part of perioperative pain control. However, many states have enacted opioid-limiting legislation to reduce perioperative opioid prescribing. The aim of this study was to evaluate the impact of time and state legislation on perioperative opioid prescribing in TAA.
Methods:
This study is a retrospective, observational review of 90-day perioperative opioid prescribing in 1,829 patients undergoing TAA throughout the United States using a large insurance database. Initial and cumulative volumes and rates of opioid prescription filling were recorded along with baseline patient and operative characteristics. Dates of state legislation enactment were also recorded. Student t-tests, analysis of variance (ANOVA), and multivariable linear and logistic regression were utilized to analyze the impact of time and state legislation on opioid prescription filling.
Results:
In the 90-day perioperative time period, initial and cumulative opioid prescription filling in oxycodone 5-mg equivalents has decreased significantly from 2010 (63.8 initial and 163.3 cumulative oxycodone 5-mg equivalents filled) to 2019 (41.1 initial and 67.2 cumulative oxycodone 5-mg equivalents filled). States with opioid-limiting legislation saw larger and more significant reductions in initial and cumulative opioid prescription filling pre-act to post-act (63.3 to 50.6 oxycodone 5-mg equivalents filled with legislation vs 61.4 to 51.9 oxycodone 5-mg equivalents filled without legislation initial and 146.4 to 93.3 oxycodone 5-mg equivalents filled with legislation vs 125.1 to 108.6 oxycodone 5-mg equivalents filled without legislation cumulative).
Conclusion:
This study demonstrates that orthopaedic surgeons in states with opioid-limiting legislation have responded by significantly reducing 90-day perioperative opioid prescribing in TAA. These results encourage states without legislation to enact opioid-specific laws to reduce opioid prescribing.
