In team-based medical tasks, digital tools facilitate information among medical experts to support patient safety. Although generally beneficial, Electronic Health Records (EHRs) have not completely mitigated communication and clinical decision errors. The design of systems meant to facilitate information-transfer among care teams has been hampered by a knowledge gap of communication and information integration needs for healthcare professionals. The EHR "note," meant to record and share patient details, has seen many iterations and changes in structure and organization. Use of EHR notes is a diagnostic task that requires convergent decision making. We examined the effects of structure and consistency on information integration and decision-making. One-hundred and seventeen students reviewed sets of curriculum documents and completed several decision-making performance measures. We also investigated how individual differences in working memory impacted the review task under various formatting conditions. Those with higher working memory scores were also more accurate in decision making when reviewing unstructured documents. Relationships between cognitive capacity and decision-making were mitigated by structured formatting. We discuss the impact of cognitive ability on search patterns and decision-making, as well as the mitigating capabilities of structured formatting. Applications are discussed at the theoretical and applied levels. [The dissertation citations contained here are published with the permission of ProQuest LLC.
