Critical Thinking in Critical Care: Five Strategies to Improve Teaching and Learning in the Intensive Care Unit

Abstract

Critical thinking, the capacity to be deliberate about thinking, is increasingly the focus of undergraduate medical education, but is not commonly addressed in graduate medical education. Without critical thinking, physicians, and particularly residents, are prone to cognitive errors, which can lead to diagnostic errors, especially in a high-stakes environment such as the intensive care unit. Although challenging, critical thinking skills can be taught. At this time, there is a paucity of data to support an educational gold standard for teaching critical thinking, but we believe that five strategies, routed in cognitive theory and our personal teaching experiences, provide an effective framework to teach critical thinking in the intensive care unit. The five strategies are: make the thinking process explicit by helping learners understand that the brain uses two cognitive processes: type 1, an intuitive pattern-recognizing process, and type 2, an analytic process; discuss cognitive biases, such as premature closure, and teach residents to minimize biases by expressing uncertainty and keeping differentials broad; model and teach inductive reasoning by utilizing concept and mechanism maps and explicitly teach how this reasoning differs from the more commonly used hypothetico-deductive reasoning; use questions to stimulate critical thinking: "how" or "why" questions can be used to coach trainees and to uncover their thought processes; and assess and provide feedback on learner's critical thinking. We believe these five strategies provide practical approaches for teaching critical thinking in the intensive care unit.

Oligoarticular Hemarthroses and Osteomyelitis Complicating Pasteurella Meningitis in an Infant

“…Efficient coordination of care led to appropriate therapeutic intervention and complete diagnostic evaluation. While Type 2 thinking played a pivotal role in this case, many agree that improvement in both type 1 and type 2 critical thinking patterns is one of the most effective strategies in reducing diagnostic errors [ 17 , 18 ]. Physicians must acknowledge that metacognition, or thinking about thinking, is required to not only recognize cognitive biases to prevent anchoring prematurely to a diagnosis but also to expose and subsequently fill knowledge gaps to deliver optimal patient care and achieve better outcomes [ 18 ].…”

Self-esteem enhancement as a strategy for promoting the mental health and averting the occupational problems of nurses

“…Critical thinking refers to the flexible use of existing knowledge and experience, based on problem analysis and induction reasoning and, ultimately, arriving at a reasonable judgment and a correct choice. 31 Critical thinking, as a basis for clinical decision-making, is directly related to the quality of clinical care services. Studies have shown that nurses' self-esteem is significantly and positively related to critical thinking.…”

Critical Care Education Day: A Novel, Multidisciplinary, and Interactive Critical Care Education Session for Emergency Medicine Residents

“…However, the classroom teaching format has limitations in that it does not train the audience to integrate cognitive and procedural tasks under time constraints [5]. Furthermore, imparting knowledge of complex critical care topics to junior residents without adequate exposure to direct patient care may hinder their ability to properly absorb the information [6][7][8][9].…”
