Demographic, Comorbidity, and Episode of Care Trends in Primary Hip Arthroplasty: 2008 to 2018

摘要

While previous studies have provided insight into time-trends in age and comorbidities of total hip arthroplasty (THA) patients, there is limited recent literature from within the past decade. The implication of these findings is relevant due to the projected THA volume increase and continued emphasis on healthcare system cost-containment policies. Therefore, the purpose of this study was to identify trends in THA patient demographics, comorbidities, and episode of care from 2008 to 2018. Methods?The National Surgical Quality Improvement Program (NSQIP) was queried to identify patient demographics, comorbidities, and episodes of care outcomes in patients undergoing primary THA from 2008 to 2018 (n?=?216,524). Trends were analyzed using analysis of variances for continuous variables, while categorical variables were analyzed using chi-squared or Monte Carlo tests, where applicable. Results?From 2008 to 2018, there were no clinically significant differences in age and body mass index (BMI) in patients with BMI over 40?kg/m2. However, modifiable comorbidities including patients with hypertension (60.2% in 2008, 54.3 in 2018%, p?
