Resident involvement during primary total hip arthroplasty did not increase 30-day complication rates, according to study results.

Researchers selected 13,109 patients from the National Surgical Quality Improvement Program database who underwent primary total hip arthroplasty (THA) between 2005 and 2012.

Overall, 26.4% of the procedures were performed with resident involvement. Although resident cases had longer operative times and resulted in more readmissions, study results showed more transfusions were performed in the non-resident group. However, the researchers found no differences in overall complication rates between non-resident cases and resident cases, with complication rates at 4.5% for non-resident cases, 3.8% for junior resident cases, 4.8% for senior resident cases and 4.6% for fellow cases.

According to multivariate logic regression with propensity score inclusion, independent risk factors for complications included increasing age, increasing ASA class, obesity, chronic obstructive pulmonary disease, bleeding disorder, history of stroke with neurological deficit, history of cardiac surgery and decreased preoperative hematocrit.
