Clinical reasoning is the cognitive process used by healthcare professionals to gather and analyze patient data, evaluate it, and make clinical decisions regarding diagnosis and treatment. It involves critical thinking, problem-solving, and decision-making skills, as well as the application of medical knowledge and clinical experience. Clinical reasoning is an essential component of effective and efficient patient care, ensuring that healthcare providers make accurate and timely decisions that lead to the best possible outcomes for their patients. Researchers in this area study the factors that influence clinical reasoning, such as biases, heuristics, and decision-making strategies, in order to improve the quality of healthcare delivery and patient outcomes.
