BackgroundThe demand for revision total hip arthroplasty (THA) procedures continues to increase. A growing body of evidence in primary THA suggests that preoperative opioid use confers increased risk for complication. However, it is unknown whether the same is true for patients undergoing revision procedures. The purpose of this study was to investigate whether or not there was a relationship between preoperative opioid use and surgical complications, medical complications, and healthcare utilisation following revision THA.MethodsThis is a retrospective cohort study using the Truven Marketscan database. Patients undergoing revision THA were identified. Preoperative opioid prescriptions were queried for 1 year preoperatively and were used to divide patients into cohorts based on temporality and quantity of opioid use. This included an opioid naïve group as well as an "opioid holiday" group (6 months opioid naïve period after chronic use). Demographic and complication data were collected and both univariate and multivariate analysis was then performed.Results62.5% of patients had received an opioid prescription in the year preceding surgery. Patients with continuous preoperative opioid use had higher odds of the following: infection (superficial or deep surgical site infection; OR 1.29; 95% CI, 1.03-1.62, p = 0.029), wound complication (OR 1.36; 95% CI, 1.02-1.82, p = 0.037), sepsis (OR 1.90; 95% CI 1.08-3.34, p = 0.026), and revision surgery (OR 1.54, 95% CI, 1.28-1.85, p < 0.001). This group also had higher care utilisation including extended length of stay, non-home discharge, 90-day readmission, and emergency room visits (p < 0.001). An opioid holiday mitigated some of this increased risk as this cohort has baseline (i.e. same as opioid naïve) risk (p > 0.05 for all comparison).ConclusionsOpioid use prior to revision THA is common and is associated with increased risk of postoperative complication. Given that risk was reduced by a preoperative opioid holiday, this represents a modifiable risk factor which should be discussed and addressed preoperatively to optimise outcomes.
