Collaborate with cardiac surgeons, human factor engineers and computer scientists to improve safety of cardiac surgery by developing novel intraoperative process models integrating cognitive load to support human performance and enhance patient safety.
We are focusing on three specific aims:
- Develop standardized surgical process models for two common procedures in cardiac surgery (aortic valve replacement and coronary artery bypass surgery) using the Little-JIL software platform.
- Evaluate these process models by applying static analyses and discrete event simulations to detect where coordination and task sequence errors might occur as well as to identify and quantify vulnerabilities that are created when humans or devices perform tasks incorrectly.
- Perform discrete event simulations of these processes performed in a realistic simulated cardiovascular operating room environment. Use evaluation results to iteratively improve the process models by addressing vulnerabilities and improved support for non-nominal situations, and enhance the clinicians’ understanding of an on-going surgical process by providing a user-interface, or view, of the current state of that process.
If our approach is successful, we believe that it may significantly contribute to reduction of the current high rate of Preventable Adverse Events (PAEs) and become the basis for surgical community participation in continuously improving standards of care. Standardized process models in cardiac surgery may reduce variability and may ultimately translate into the application of evidence-based best practice to every patient and every time.
Student role: Coordinate with simulation specialists and research group to finalize simulated intra-operative crisis scenarios occurring during cardiac surgery; Aid in data collection prep, including research protocol dry runs, scenario dry runs, walkthroughs; Assist in subject recruitment and data collection; Coordinate all of these efforts with multi-site research group representing diverse academic backgrounds
Expectations of student: Effective and timely communication; Dedicated time via physical meetings and teleconferences on a weekly or bi-weekly basis; Some degree of domain knowledge of cardiac surgery processes. We expect a student to be available at least 1 day per week. MS3+ are preferred. Some background in human factors research and cardiac surgery processes; Familiarity in human subjects research.
The mentor for this project is available as needed, primary through email.
