BackgroundA prerequisite for a valuable surgical case log is the ability to perform an accurate self-assessment. Studies have shown mixed results when examining residents' ability to self-assess on varying tasks. We sought to examine the correlation between residents' self-assessment and staff surgeons' evaluation of surgical involvement and competence in performing primary total knee (TKA) and hip arthroplasty (THA).MethodsWe used the intraclass correlation coefficient (ICC) to evaluate interobserver agreement between residents' self-perception and staff surgeons' assessment of involvement. An assessment of competency was performed using a categorical global scale and evaluated with the κ statistic. We piloted a structured surgical skills assessment form as an additional objective appraisal of resident involvement.ResultsWe analyzed assessment data from 65 primary TKA and THA cases involving 17 residents and 17 staff surgeons (93% response rate). The ICC for resident involvement between residents and staff surgeons was 0.80 (95% confidence interval [CI] 0.69-0.88), which represents substantial agreement. The agreement between residents and staff surgeons about residents' competency to perform the case had a κ value of 0.67 (95% CI 0.50-0.84). The ICC for resident, staff surgeon and third-party observer using the piloted skills assessment form was 0.82 (95% CI 0.75-0.88), which represents substantial agreement.ConclusionThis study supports the ability of orthopedic residents to perform self-assessments of their degree of involvement and competency in primary TKA and THA. Staff surgeons' assessment of resident involvement correlated highly with the surgical skills assessment form. Self-assessment is a valuable addition to the surgical case log.
