RESUMO
Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are commonly performed procedures that are expected to continue increasing in demand. Although they are proven to be safe and effective, emergency room (ER) visits or hospital readmissions within 90 days after these procedures account for more than one-third of the total cost of postacute care. Purpose: We sought to identify changes in reasons for 90-day ER visits and readmissions after total joint arthroplasty (TJA) during a 5-year period over which rapid recovery protocols evolved. Methods: We conducted a retrospective cohort study comparing 1980 patients who had undergone TJA from July 2017 to June 2018 with a previously published cohort of 7466 patients who had undergone TJA from July 2013 to June 2017. All procedures were performed at a single institution. Changes in the proportion of patients returning for medical and surgical reasons were compared using univariate analysis. Results: For patients discharged home, the 2017-2018 cohort showed a significant reduction in the proportion of ER visits due to pain and swelling and wound infection and an increase in visits for medical reasons. This cohort had a higher proportion of readmissions for medical reasons. In patients discharged to a skilled nursing facility (SNF), similar reasons for ER visits were observed across time periods, and a decrease in the proportion of readmissions for wound infections was observed in the 2017-2018 cohort. Falls and nausea, vomiting, or diarrhea increased significantly to account for 9.5% of readmissions each in 2017-2018. Conclusion: The results of a comparison of 2 cohorts demonstrate the heterogeneous and dynamic nature of unplanned return-to-hospital events and the importance of patient support throughout the surgical episode. As we strive toward minimizing ER visits and readmissions after TJA, rapid recovery protocols must continue to evolve to address the complexity of this patient population.
RESUMO
STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Racial disparities in postoperative outcomes are unfortunately common. We present data assessing race as an independent risk factor for postoperative complications after spine surgery for Native American (NA) and African American (AA) patients compared with Caucasians (CA). METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for spine procedures performed in 2015. Data was subdivided by surgery, demography, comorbidity, and 30-day postoperative outcomes, which were then compared by race. Regression was performed holding race as an independent risk factor. RESULTS: A total of 4803 patients (4106 CA, 522 AA, 175 NA) were included in this analysis. AA patients experienced longer length of stay (LOS) and operative times (P < .001) excluding lumbar fusion, which was significantly shorter (P = .035). AA patients demonstrated higher comorbidity burden, specifically for diabetes and hypertension (P < .005), while NA individuals were higher tobacco consumers (P < .001). AA race was an independent risk factor associated with longer LOS across all cervical surgeries (ß = 1.54, P <.001), lumbar fusion (ß = 0.77, P = .009), and decompression laminectomy (ß = 1.23, P < .001), longer operative time in cervical fusion (ß = 12.21, P = .032), lumbar fusion (ß = -24.00, P = .016), and decompression laminectomy (OR = 20.95, P < .001), greater risk for deep vein thrombosis in lumbar fusion (OR = 3.72, P = .017), and increased superficial surgical site infections (OR = 5.22, P = .001) and pulmonary embolism (OR = 5.76, P = .048) in decompression laminectomy. NA race was an independent risk factor for superficial surgical site infections following cervical fusion (OR = 14.58, P = .044) and decompression laminectomy (OR = 4.80, P = .021). CONCLUSION: AA and NA spine surgery patients exhibit disproportionate comorbidity burden and greater 30-day complications compared with CA patients. AA and NA race were found to independently affect rates of complications, LOS, and operation time.
