RESUMO

STUDY OBJECTIVE: Opioid use has been associated with significant morbidity and mortality in the United States. Studies within kidney transplantation have also shown increased risk of mortality, graft loss, and complications in kidney transplant recipients who use opioids prior to transplant. The objective of this analysis was to identify if recent pretransplant opioid exposure would be an effective risk-stratifier for patients at risk for readmissions and readmission costs. Further, the objective was to see if a brief assessment of recent opioid use could predict chronic opioid use post-transplant." PATIENTS AND DESIGN: This study was a single-center, retrospective cohort analysis of adult renal transplant recipients between January 2010 and December 2016 assessing the impact of pretransplant opioid use on posttransplant readmissions at 1 year postsurgery, as well as it's ability to identify patients at risk of chronic opioid use post-transplant. Opioid use was identified using medication reconciliation or a national prescription database, and readmissions and normalized costs for hospitalizations were identified via the Vizient clinical database. MAIN RESULTS: Pretransplant opioid exposure occurred in 271 (24%) of 1129 patients transplanted during the study time period. There were no differences in index hospitalization length of stay or cost; however, patients with opioid exposure were significantly more likely to have been admitted within 1-year postsurgery (51 vs. 43%, p = 0.023), had more readmissions per patient (0.93 vs. 0.72, p = 0.010), and had higher normalized readmissions costs ($12,556 vs. $8344, p = 0.009). Patients with opioid exposure were also more likely to be admitted for readmissions, had more admissions per patient, and had higher readmission costs at 30 and 90 days postsurgery. There were no differences in preventability of readmissions between cohorts or in general causes of readmissions. A multivariable logistic regression demonstrated that being opioid experienced and having a history of diabetes mellitus were independently associated with readmissions at 1 year postsurgery. In addition, having opioid exposure at the time of transplant, a history of diabetes mellitus, and younger age were independently associated with chronic opioid use after transplant. CONCLUSION: This study demonstrated that recent exposure to opioids prior to kidney transplant was significantly and independently associated with increased readmissions and readmission costs at multiple timepoints up to 1 year posttransplant as well as chronic opioid use after transplant.It also demonstrated that a brief assessment of recent opioid use may be able to identify patients at risk for chronic opioid use. Because opioid use is associated with multiple diseases, it is important to continue to study the association of opioid use, and the potential for disease-modifying interactions, with various clinical outcomes.
