Assessment of Didactic Transesophageal Echocardiography Education During Anesthesia Residency

Transesophageal echocardiography can be a useful monitor during noncardiac surgery, in patients with comorbidities and/or undergoing procedures associated with substantial hemodynamic changes. The goal of this study was to investigate if transesophageal-echocardiography-related knowledge could be acquired during anesthesia residency.

After institutional review board approval, a prospective observational study was performed in two anesthesiology residency programs. After a 41-week didactic transesophageal-echocardiography-education curriculum residents' exam scores were compared to baseline. The educators' examination was validated against the National Board of Echocardiography's Examination of Special Competence in Advanced Perioperative Transesophageal Echocardiography.

After the 41-week course, clinical anesthesia (CA)-3 exam scores increased 12% compared to baseline (P = .03), CA-2 scores increased 29% (P = .007), and CA-1 scores increased 25% (P = .002). Pearson correlation coefficient between the educators' exam score and the special competence exam percentile rank was 0.69 (P = .006). Pearson correlation coefficient between the educators' exam score and the special competence exam scaled score was 0.71 (P = .0045).

The 41-week course resulted in significant increases in exam scores in all 3 CA-classes. While didactic knowledge can be learned by anesthesiology residents during training, it requires significant time and effort. It is important to educate residents in echocardiography, to prepare them for board examinations and to care for the increasingly older and sicker patient population. Further work needs to be done to determine optimal methods to provide such education.
