- To explore the utility of computer simulations in refining medical education and error calibration.
Main Methods:
- Analysis of decision-making data from five expert cardiologists.
- Utilizing a computer simulation of a congenital heart disease emergency case.
Main Results:
- Substantial agreement was found on the initial emergency response step.
- Significant disagreement emerged regarding subsequent diagnostic and treatment steps.
- The number of steps to problem resolution varied widely among experts (6-11 steps).
- One expert's simulation sequence led to a fatal outcome.
Conclusions:
- Expert consensus exists for initial emergency actions in simulated congenital heart disease.
- Variability in expert problem-solving highlights the need for standardized training protocols.
- Computer simulations provide valuable data for calibrating student errors and improving medical training.
Abstract:
Analysis of data from five expert cardiologists indicates substantial agreement on the first step to be taken in response to an emergency case of computer-simulated congenital heart disease. There was little or no agreement among these same subjects on the specific steps undertaken following their initial response. The problem was solved in 11, 10, 8, and 6 steps by four of the cardiologists. The problem-solving sequence employed by one expert resulted in the patient's death. It is concluded that while the behavior of experts in the hospital and clinic is the primary means of evaluating successful student performance, computer simulations of patient cases offer the opportunity to use expert data in the calibration of student error.
