Objective: The purpose of the current study was to determine the effectiveness of using cognitive task analysis (CTA) to develop a curriculum to teach the behavioral skills and the cognitive strategies of a percutaneous tracheostomy (PT) placement. Methods: Postgraduate 2, 3, and 4 general surgery residents were randomly assigned to either the CTA group (N = 9) or the control group (N = 11). The CTA group was taught percutaneous tracheostomy placement using the CTA curriculum. The control group received the traditional curriculum. Results: The CTA group performed significantly higher on the PT procedure at 1 month (CTA: 43.5 ± 3.7, control 35.2 ± 3.9, P = .001) and at 6 months post-instruction (CTA: 39.4 ± 4.2, control: 31.8 ± 5.8, P = .004). In addition, the CTA group demonstrated superior cognitive strategies than the control group (CTA: 25.4 ± 5.3, control: 19.2 ± 2.0, P = .004). Conclusions: The use of CTA was effective in improving the cognitive processes and technical skills of performing a PT for surgical residents.
