Hoofbeats: Hyponatremia Consult Case
Clinical reasoning has traditionally been regarded as a cognitive process, however, it is also a contextually situated activity. Many contextual and environmental factors affect our cognitive load and reasoning approach. In addition, academic training often promote routine expertise where someone effectively uses sophisticated knowledge-memory structures to solve routine problems. In this episode of Core IM, the team will discuss a different kind of expertise as they explore adaptive expertise in Hoofbeats: Hyponatremia Consult Case.

Podcasts and Audio Content
Welcome to Core IM, a virtual medical community! Core IM strives to empower its colleagues of all levels and backgrounds with clinically applicable information as well as inspire curiosity and critical thinking. Core IM promotes its mission through podcasts and other multimodal dialogues. ACP has teamed up with Core IM to offer continuing medical education, available exclusively to ACP members by completing the CME/MOC quiz.
- Reasoning is not just a cognitive process, but also a contextually situated activity. We do not reason in a vacuum. Unfamiliar environment, ambiguous clinical questions, relative domain expertise, emotional interference, personal comfort level of the case are examples of many contextual factors that can add to one's cognitive load AND alter their reasoning approach.
- Situation awareness is something that precedes, prepares, and “primes” our mode of thinking and is largely affected by a person’s goals and expectations. Having clearly defined clinical goals is crucial to effective reasoning.
- When someone needs to operate with insufficient domain knowledge, there is the natural tendency to slow down AND to deploy different reasoning strategies such as backward reasoning. The process can be deliberate or completely unintentional.
- A clinician employing “hypothesis-driven reasoning” (“working backwards”) starts with a clinical problem, generates a series of hypotheses about the patient’s illness, then tests each of these against the available clinical data. It is a time and effort consuming process.
- How rigorously one deploys such a strategy is often not dependent on the person’s actual expertise but rather their perceived familiarity of the problem. “Cognitive ease” refers to the phenomenon when we face a common diagnosis or symptom, the impression of familiarity can create a false sense of ease, which makes us more susceptible to diagnostic errors.
- Adaptive expertise entails someone’s ability to use existing clinical knowledge structures to come up with a novel solution when they face a complex, unfamiliar problem. An adaptive expert tends to have a solid knowledge structure of their own domain, is not satisfied by complacency, and is cognitively ready to brace novel knowledge in an unknown territory.
