| Abstract | This study used cognitive task analysis (CTA) knowledge elicitation strategies to find the percentage and type of information that experts omit when describing how to perform a surgical procedure. CTA is a method by which a trained analyst can extract and capture information that has been automated and is non-conscious to an expert. This information includes critical decision points and judgments involved in the expert’s performance of the procedure. Based on the current research literature, the hypothesis for this study was that surgical experts would omit approximately 70% of the critical decision steps necessary to perform the Open Cricothyrotomy and Central Venous Catheter surgical procedures. More specifically, this study sought to determine if there is a difference in knowledge omissions based on the experts’ prior knowledge of the procedures.; This descriptive study took a mixed-methods approach. Qualitative methods were used to conduct semi-structured interviews while quantitative methods were used. to analyze the data by using frequency counts to determine how much information was omitted when compared with the final, expert-approved, “gold standard.” The “gold standard” is an aggregate of the information elicited from six medical faculty at the University of Southern California, Keck School of Medicine. Results showed that experts for the Open Cricothyrotomy surgical procedure omitted 76.92% of the decision steps, while experts for the Central Venous Catheter procedure omitted 34.52% of the decision steps. Limitations of the study and implications for future research and task complexity are discussed. |
