Abstract
IntroductionPrescription opioid consumption in the United States is a well-known public health problem, however, the deleterious effect of opioids may not be fully understood. The purpose of this study was to investigate the relationship between preoperative opioid use and patient-reported outcomes two years after shoulder surgery. We hypothesized preoperative opioid use would be predictive of worse two-year patient reported outcome scores. MethodsPatients undergoing shoulder surgery at an urban institution from June 2015 to July 2017 were prospectively enrolled into our orthopaedic registry. Preoperative opioid use and its association to patient outcome scores was retrospectively analyzed through bivariate analysis. Multivariate analysis was used to control for confounding variables and to determine independent predictors of two-year outcome scores. ResultsPreoperative opioid use was associated with significantly worse scores on all two-year patient reported outcomes, and less improvement in PROMIS Physical Function and Numeric Pain Score (NPS) Body Pain two years postoperatively. Multivariate analysis showed preoperative opioid use to be an independent predictor of worse two-year scores in PROMIS Physical Function, PROMIS Pain Interference, PROMIS Social Satisfaction, American Shoulder and Elbow Surgeons Standardized Shoulder Form and NPS Operative Site. Preoperative opioid use was not an independent predictor of change in any outcome measure. ConclusionPreoperative opioid use was associated with worse scores on all two-year patient reported outcomes, and after controlling for confounders, preoperative opioid use was predictive of worse scores in several two-year outcome measures. To our knowledge, this is one of the few studies investigating the impact of preoperative opioid use on postoperative outcomes after shoulder surgery.
