Heuristics in Managing Complex Clinical Decision Tasks in Experts' Decision Making

Abstract

BACKGROUND: Clinical decision support is a tool to help experts make optimal and efficient decisions. However, little is known about the high level of abstractions in the thinking process for the experts. OBJECTIVE: The objective of the study is to understand how clinicians manage complexity while dealing with complex clinical decision tasks. METHOD: After approval from the Institutional Review Board (IRB), three clinical experts were interviewed the transcripts from these interviews were analyzed. RESULTS: We found five broad categories of strategies by experts for managing complex clinical decision tasks: decision conflict, mental projection, decision trade-offs, managing uncertainty and generating rule of thumb. CONCLUSION: Complexity is created by decision conflicts, mental projection, limited options and treatment uncertainty. Experts cope with complexity in a variety of ways, including using efficient and fast decision strategies to simplify complex decision tasks, mentally simulating outcomes and focusing on only the most relevant information. APPLICATION: Understanding complex decision making processes can help design allocation based on the complexity of task for clinical decision support design.
