Does Preoperative Opioid Consumption Increase the Risk of Chronic Postoperative Opioid Use After Total Joint Arthroplasty?

BACKGROUND: Risk-factor identification related to chronic opioid use after surgery may facilitate interventions mitigating postoperative opioid consumption. We evaluated the relationship between opioid use preceding total hip arthroplasty (THA) and total knee arthroplasty (TKA), and chronic use postoperatively, and the risk of chronic opioid use after total joint arthroplasty. METHODS: All primary THAs and TKAs performed during a 6-month period were identified. Opioid prescription and utilization data (in oxycodone equivalents) were determined via survey and electronic records. Relationship between preoperative opioid use and continued use >90 days after surgery was assessed via Chi-square, with significance set at P < .05. RESULTS: A total of 415 patients met inclusion criteria (240 THAs and 175 TKAs). Of the 240 THAs, 199 (82.9%) patients and of the 175 TKAs, 144 (82.3%) patients agreed to participate. Forty-three of 199 (21.6%) THA patients and 22 of 144 (15.3%) TKA patients used opioids within 30 days preoperatively. Nine of 199 (4.5%) THA and 10 of 144 (6.9%) TKA patients had continued use of opioids for >90 days postoperatively. Preoperative opioid consumption was significantly associated with chronic use postoperatively for THA (P = .011) and TKA (P = .024). Five of 43 (11.6%) THA and 4 of 22 (18.2%) TKA patients with preoperative opioid use had continued use for >90 days postoperatively. For opioid naïve patients, 2.6% (4/156) of THA and 4.9% (6/122) of TKA patients had chronic use postoperatively. CONCLUSIONS: Preoperative opioid use was associated with nearly 5-fold and 4-fold increase in percentage of patients with chronic opioid use after THA and TKA, respectively. Surgeons should counsel patients regarding this risk and consider strategies to eliminate preoperative opioid use.
