Effect of Perioperative Opioid Use on Patients Undergoing Hip Arthroscopy

Background: Opioids are commonly used to treat postoperative pain; however, guidelines vary regarding safe opioid use after hip arthroscopy. Purpose/Hypothesis: The purposes were to (1) identify risk factors for persistent opioid use, (2) assess the effect of opioid use on outcomes, and (3) describe common opioid prescribing patterns after hip arthroscopy. It was hypothesized that preoperative opioid use would affect complication rates and result in greater postoperative opioid use. Study Design: Case-control study; Level of evidence 3. Methods: The Utah State All Payer Claims Database was queried for patients who underwent hip arthroscopy between January 2013 and December 2017. Included were patients >= 14 years of age at index surgery with continuous insurance. Patients were separated into acute (<3 months) and chronic (>= 3 months) postoperative opioid use groups. Primary outcomes included revision surgery, complications (infection, pulmonary embolism/deep venous thrombosis, death), emergency department (ED) visits, and hospital admissions. Multivariate logistic regression was utilized to identify factors associated with the outcomes. Results: Included were 2835 patients (mean age, 47 years; range, 14-64 years), of whom 2544 were in the acute opioid use and 291 were in the chronic opioid use group. Notably, 91% of the patients in the chronic group took opioid medications preoperatively, and they were more than twice as likely to carry a mental health diagnosis (P < .01). Patients in the acute group had a significantly shorter initial prescription duration, took fewer opioid pills, and had fewer refills than those in the chronic group (P < .01 for all). Patients in the chronic group had a significantly higher risk of postoperative ED visits (odds ratio [OR], 2.76; P = .008), hospital admission (OR, 3.02; P = .002), and additional surgery (P = .003), as well as infection (OR, 2.55; P < .001) and hematoma (OR, 2.43; P = .030). Patients who had used opioids before hip arthroscopy were more likely to need more refills (P < .01). A formal opioid use disorder diagnosis correlated significantly with postoperative hospital admissions (OR, 3.83; P = .044) and revision hip arthroscopy (OR, 4.72; P = .003). Conclusion: Mental health and substance use disorders were more common in patients with chronic postoperative opioid use, and chronic postoperative opioid use was associated with greater likelihood of postoperative complications. Preoperative opioid use was significantly correlated with chronic postoperative opioid use and with increased refill requests after index arthroscopy.
