PurposeOpioids are a mainstay for pain management after total joint arthroplasty (TJA). The prevalence and risk factors for prolonged opioid use after TJA are important to understand to help slow the opioid epidemic. We aim to summarize and evaluate the prevalence and time trend of prolonged opioid use after TJA and pool its risk factors.MethodsFollowing the preferred reporting items for systematic reviews and meta-analysis statement, we systematically searched PubMed, the Cochrane Library, and EMBASE, etc. from inception up to October 1, 2019. Cohort studies reporting risk factors for prolonged opioids use (≥ 3 months) after TJA were included. Studies characteristics, risk ratios (RR), and prevalence of prolonged opioid use were extracted and synthesized.ResultsA total of 15 studies were published between 2015 and 2019, with 416,321 patients included. 12% [95%CI 10-14%] of patients had prolonged opioid use after TJA and its time trend was associated with median enrollment years (P = 0.0013). Previous opioid use (RR = 1.73; P < 0.001), post-traumatic stress disorder (RR = 1.34; P < 0.001), benzodiazepine use (RR = 1.38; P < 0.001), tobacco abuse (RR = 1.26; P < 0.001), fibromyalgia (RR = 1.51; P < 0.001), and back pain (RR = 1.34; P < 0.001) were the largest effective risk factors for prolonged use of opioids.ConclusionsTo our knowledge, this is the first meta-analysis determining the risk factors of prolonged opioid use and characterizing its rate and time trend in TJA. Understanding risk factors for patients with higher potential for prolonged opioids use can be used to implement appropriate management strategies, reduce unsafe opioid prescriptions, and decrease the risk of prolonged opioid use after TJA.
