Abstract

Remember the first time you watched a master clinician work through a diagnostic dilemma or clinical unknown case and easily arrive at the correct diagnosis That person most likely seemed calm with little stress asked the right questions at the right time and often reflected on the information they gleaned from the case If the clinician described how they arrived at their diagnosis you were probably in awe at how they solved the case using their critical thinking skills While critical thinking is essential for effective patient care this highly complex process is not easily taught or measuredCritical thinking can be seen as having two components 1 a set of information and belief generating and processing skills and 2 the habit based on intellectual commitment of using those skills to guide behavior1 Thus while possessing medical knowledge is a necessary part of critical thinking many factors play a role in the process such as data gathering skills clinical context patient preferences personal reactions to stress and reflective practice Research demonstrates that some stress and thoughtful reflection are beneficial to the thinking process2 3 4 yet there is no consensus on how to positively manage stress or use reflection in daily clinical care Two articles56 in this issue of JGIM explore the areas of stress and reflection on critical thinking among traineesThe study by Pottier and colleagues5 explored the role of stressors on a medical student’s history taking physical examination and clinical reasoning The authors performed a study of medical students who participated in two scenarios with standardized patients with familiar disease processes Students conducted a history and physical exam and were asked to generate a diagnosis with a differential based on the clinical data obtained during the scenario During their patient encounters students were presented with two stressors extrinsic and intrinsic Extrinsic stressors were manifested by the patient’s cooperativeness and mood such that the patient was either a aggressive with negativity and lacked confidence in the student’s competence or b pleasant without challenges to the student Intrinsic stressors were defined as stressful components integral to the encounter based on clinical presentation and were exhibited by a patient with either high clinical severity dyspnea from an acute pulmonary embolism or low clinical severity acute abdominal pain in a relatively healthy patient Students were randomized to two of four clinical scenarios with a balance of high and low clinical severity in an aggressive or pleasant patient Subjective stress and anxiety responses were assessed before and after each experience as were completeness in physical examination communication skills diagnostic accuracy and differential diagnosis argumentation The authors found that each type of stress had a different effect on a student’s anxiety and clinical performance Results indicated that extrinsic stress increased personal anxiety but led to more accurately performing the clinical examination and increased interpersonal skills Intrinsic stress did not change the students’ anxiety but demonstrated increases in diagnostic accuracy and differential diagnosis scores The perceived cognitive difficulty of the task was a strong factor in most of the stress and performance variables When the clinical scenario had high extrinsic and intrinsic stress students no longer showed improved clinical examination or communication skills Interestingly the initial exposure in the first case to extrinsic and intrinsic stress did not influence the outcomes of the second caseIn their work on reflection in decision making Monteiro and colleagues6 aimed to examine how a resident’s clinical experience and selfdirected decisions to reflect on their diagnosis affected the accuracy of their decisions Using a randomized mixed design 47 medical interns and residents were presented with 16 computerized cases where they were given a patient’s primary complaint medical history a representative photograph diagnostic tests and images On their first review of the case first pass trainees were asked to arrive at a diagnosis as fast as they could presumably their response in the automatic or intuitive System 1 mode of thinking On the second pass residents were then randomly assigned to review either the full case again or a brief description of the case and asked to reflect on their decision and revise their diagnosis encouraging System 2 mode analytic thinking Residents arrived at the correct diagnosis in 5864  of cases with no significant differences in diagnostic accuracy among the three resident training levels Only 8  of diagnoses were revised with minimally significant changes in diagnostic accuracy from the first pass to the second Having access to the full case on the second pass resulted in a higher rate of diagnosis revision but did not affect diagnostic accuracyBoth aforementioned studies explored factors that influence critical thinking but limitations of these studies should be considered First both studies involved trainees and not practicing clinicians with more extensive medical expertise For the medical students their limited medical knowledge and clinical experience may have been most influential on their stress and critical thinking as their perceived cognitive difficulty of the task itself was the greatest predictor in their performance In the case of the medicine residents these trainees also appeared to be limited in their medical knowledge given their low diagnostic accuracy in the study 5864  correct diagnoses Thus no amount of analytic thinking without access to outside resources may have helped improve their diagnostic thinking Second both studies used simulation and not patient encounters While it is unclear how these results may be extrapolated to performance in actual clinical practice simulation is successfully used in both teaching and evaluation in lieu of patient interactionsWhile these studies have limitations the topics of stress and reflection in critical thinking are of high interest to clinicians Similar to what occurs in high performing athletes the medical literature has suggested that “good” stress can positively influence performance compared to “bad” or no stress23 Thus just as athletes spend extensive amounts of time training to overcome obstacles and stress perhaps a part of medical education should involve ways to teach students and residents how to lessen negative stress and improve positive stress Educating trainees about personal wellness is currently being addressed by the Accreditation Council on Graduate Medical Education ACGME which requires each residency program to provide resident and faculty education on trainee alertness and fatigue mitigation7 Understanding and educating about stress and its impact on clinical care may be as critical as knowledge of fatigue and its effects on personal and professional wellbeing As shown in the Pottier article having good intrinsic stress increased students’ clinical reasoning while extrinsic stress helped students focus on communication skills These positive stress effects influenced critical thinking and the outcomes of the clinical encounter Finding ways in the curriculum to educate medical students about the important connection between communication and critical thinking can be done successfully as was seen in a preclinical course at Johns Hopkins University School of Medicine8 This course found that teaching medical students the integration of communication and clinical reasoning was a viable method to improve therapeutic relationships with patients while reducing the potential for medical error and harm Perhaps more programs should explore the effects of teaching these skills together as a way to lessen bad stress and improve good stressReflective practice has been described as an essential part of professional competence9 It is often considered to be an iterative process that occurs in more senior clinicians especially when faced with a diagnostically challenging patient10 While a divergence of opinion exists regarding whether or not reflective practice is useful or can be taught educators should consider ways to best foster reflective practice early in clinical training as it is deliberate practice and reflection that pushes us to be better clinicians and teachersWhether reflective practice and stress are helpful harmful or uninfluential on critical thinking we should all remember that our goal in medicine is to establish effective therapeutic relationships with patients while reducing diagnostic errors Recognizing what a patient brings to an encounter with respect to their biological cultural and psychosocial background is critical in decision making Understanding how we each react to stressors in a clinical context and how this may negatively or positively influence our medical decision making is as important as understanding our strengths and limitations in our medical knowledge In addition reflection in practice especially when taking the time to gather more information may be critical to avoiding diagnostic errors and premature closure
