Using Self-Regulated Learning Microanalysis to Examine Regulatory Processes in Clerkship Students Engaged in Practice Questions.

Introduction: Self-regulated learning is a cyclical process of forethought, performance, and self-reflection that has been used as an assessment tool in medical education. No prior studies have evaluated SRL processes for answering multiple-choice questions (MCQs) and most evaluated one or two iterations of a non-MCQ task. SRL assessment during MCQs may elucidate reasons why learners are successful or not on these questions that are encountered repeatedly during medical education. Methods: Internal medicine clerkship students at three institutions participated in a SRL microanalytic protocol that targeted strategic planning, metacognitive monitoring, causal attributions, and adaptive inferences across seven MCQs. Responses were transcribed and coded according to previously published methods for microanalytic protocols. Results: Forty-four students participated. In the forethought phase, students commonly endorsed prioritizing relevant features as their diagnostic strategy (n = 20, 45%) but few mentioned higher-order diagnostic reasoning processes such as integrating clinical information (n = 5, 11%) or comparing/contrasting diagnoses (n = 0, 0%). However, in the performance phase, students' metacognitive processes included high frequencies of integration (n = 38, 86%) and comparing/contrasting (n = 24, 55%). In the self-reflection phase, 93% (n = 41) of students faulted their management reasoning and 84% (n = 37) made negative references to their abilities. Less than 10% (n = 4) of students indicated that they would adapt their diagnostic reasoning process for these questions. Discussion: This study describes in detail student self-regulatory processes during MCQs. We found that students engaged in higher-order diagnostic reasoning processes but were not explicit about it and seldom reflected critically on these processes after selecting an incorrect answer. Self-reflections focused almost exclusively on management reasoning and negative references to abilities which may decrease self-efficacy. Encouraging students to identify and evaluate diagnostic reasoning processes and make attributions to controllable factors may improve performance.

Exploring procedure-based management reasoning: a case of tension pneumothorax.

OBJECTIVES: Management reasoning has not been widely explored but likely requires broader abilities than diagnostic reasoning. An enhanced understanding of management reasoning could improve medical education and patient care. We conducted a novel exploratory study to gain further insights into procedure-based management reasoning. METHODS: Participant physicians managed a simulated patient who acutely decompensates in a team-based, time-pressured, live scenario. Immediately following the scenario, physicians perform a think-aloud protocol by watching video recordings of their performance and narrating their reflections in real-time. Verbatim transcripts of the think-aloud protocol were inductively coded using a constant comparative method and evaluated for themes. RESULTS: We recruited 19 physicians (15 internal medicine, one family medicine, and three general surgery) for this study. Recognizing that diagnostic and management reasoning intertwine, this paper focuses on management reasoning's characteristics. We developed three categories of management reasoning factors with eight subthemes. These are Patient factors: Acuity and Preferences; Physician factors: Recognized Errors, Anxiety, Metacognition, Monitoring, and Threshold to Treat; and one Environment factor: Resources. CONCLUSIONS: Our findings on procedure-based management reasoning are consistent with Situation Awareness and Situated Cognition models and the extant work on management reasoning, demonstrating that management is inherently complex and contextually bound. Unique to this study, all physicians focused on prognosis, indicating that attaining competency in procedural management may require planning and prediction abilities. Physicians also expressed concerns about making mistakes, potentially resulting from the scenario's emphasis on a procedure and our physicians' having less expertise in the treatment of tension pneumothorax.

The Association With Physical Fitness and Academic Performance at America's Military Medical School.

INTRODUCTION: Undergraduate and graduate medical education both have been reported to have high rates of depression, anxiety, and burnout as a result of the rigors of their educational curricula. Wellness, including physical fitness, is important to the profession because it may help mitigate these increased rates of depression and anxiety. While several studies examine physical fitness and academic performance in primary and secondary education, few studies have examined the association between fitness and performance in health professions education. Given the demands of medical school, this investigation aimed to investigate the possibility of an association between physical fitness and body mass index (BMI) with academic performance. Another goal was to examine the change in physical fitness and BMI throughout medical school. MATERIALS AND METHODS: Standardized measures of physical fitness were examined in 192 Army students from the Uniformed Services University of Health Sciences over 4 years from the classes of 2017-2019. Measurements include (1) body composition (BMI); (2) muscular endurance (timed push-ups); (3) aerobic endurance (timed run), and (4) total fitness defined as total points from sit-ups, run, and push-ups (everything but BMI). Pearson correlation analysis was conducted between physical fitness and academic performance measures such as United States Medical Licensing Examination (USMLE) Step 1, USMLE Step 2 Clinical Knowledge (CK), and average core clerkship National Board of Medical Examiners (NBME) exam scores. A repeated measures analysis of variance was conducted to examine the differences of students' fitness total points and BMI over 4 fitness measurements spanning approximately 1.7 years. RESULTS: There were weak positive correlations, 0.20 and 0.22, between USMLE Step 2 CK exam scores and push-up points and total fitness points, respectively. There also were weak positive correlations, 0.21 and 0.24, between core clerkship average NBME exam scores and push-up points and total fitness points, respectively. No statistically significant change of individual students' fitness total point change was observed (F(2.52, 334.93 = 1.37, P = 0.26)). There was also no individual BMI change (F(2.36, 274.21 = 2.78, P = .06)) over the first four assessment measurements (about 1.7 years lapse). However, the class means over the four measurements showed a decrease of fitness total points and an increase of BMI. CONCLUSIONS: Our investigation suggests that there may be correlations between physical fitness and clinical exam performance such as USMLE Step 2 CK and average core clerkship NBME exams. Although there is no statistically significant change in individual fitness total points or BMI, the study suggests that physical fitness and BMI may decline during medical school. This may be as a result of increasing academic demands while balancing clinical duties from clerkship rotations.

Low-risk myelodysplastic syndrome managed with an erythroid-stimulating agent for 10 years.

A 57-year-old man with a history of diabetes and coronary artery disease was referred to haematology for the evaluation of anaemia in the setting of non-cardiac chest pain, fatigue, dyspnoea and dizziness. Previous investigations into these recurrent symptoms focused on a re-evaluation of his known ischaemic heart disease, which required multiple percutaneous interventions with stenting several years ago. In the year leading up to his referral, the patient required two transfusions during separate hospitalisations. Previously, his chronic anaemia was attributed to chronic inflammation because of unrevealing micronutrient and endoscopic evaluations. The patient underwent a bone marrow biopsy, which demonstrated normal karyotype myelodysplastic syndrome with ringed sideroblasts. This patient was found to have favourable cytogenetics and low-risk disease. His anaemia and associated symptoms improved with the administration of an erythroid-stimulating agent. Now 75 years old, he has remained on single-agent therapy for 10 years without need of transfusion.

Hairy Cell Leukemia and Ground Water Contamination With Industrial Solvents: a Case Report.

The industrial solvents benzene and trichloroethylene (TCE) are known carcinogens, and these solvents contaminated the drinking water at Marine Corps Base Camp Lejeune from the 1950s to 1980s. Benzene and TCE are linked to the hematopoietic cancers acute myelocytic and lymphocytic leukemia and chronic lymphocytic leukemia. We report the case of a veteran stationed at Marine Corps Base Camp Lejeune during this period who developed hairy cell leukemia (HCL), a rare form of lymphocytic leukemia. We review his presentation, medical history, solvent exposure, and literature on the carcinogenicity of benzene and TCE. This patient represents a possible link of TCE or benzene to HCL. The case also informs clinicians of the updated epidemiology with regards to clinical findings for HCL.

Combat Readiness, Harm Aversion, and Promotion Eligibility: A Qualitative Study of U.S. Servicemembers Views on Tobacco Use and Control in the Military.

INTRODUCTION: More than half a century after the first Surgeon General's Report on Smoking and Tobacco Use, tobacco use remains the leading cause of preventable disease for the U.S. military. Military tobacco use impairs troop readiness, decreases productivity, reduces servicemember physical performance, and leads to chronic illness in veterans. The Department of Defense (DoD) spends considerable effort to maintain a combat ready force, and tobacco use is contradictory to these efforts. U.S. servicemember tobacco use is estimated to cost the federal government more than $6.5 billion annually. The uniqueness of military culture allows for innovative means of tobacco regulation and prevention. Our study examines the U.S. Navy cultural and servicemember perceptions to inform future tobacco control research and policies. MATERIALS AND METHODS: We developed a behavioral model of tobacco use from existing literature. Using this model as a theoretical framework, our study qualitatively examined tobacco use in the active duty Navy population stationed in Okinawa, Japan. Thirty one-on-one interviews were conducted with active duty servicemembers. Sessions were recorded, transcribed, and analyzed in MAXQDA12. RESULTS: Multiple military-specific themes were identified. Themes: (1) tobacco use is a "right," (2) the military may limit active duty servicemembers' rights, (3) tobacco restrictions are justified if they prevent harm to others, (4) tobacco restrictions are not widely enforced, (5) smoke breaks are viewed as a legitimate reason to rest at work, and (6) the benefit of tobacco is as a stimulant. Novel tobacco cessation techniques suggested by our study include: (1) expand the buddy system to create an artificial support network for tobacco cessation and (2) tie promotion eligibility to tobacco use. CONCLUSIONS: This qualitative study identifies military-specific themes from the tobacco user perspective that help to guide research and policy in reducing tobacco use among military servicemembers. Possible interventions suggested by our findings may include replacing tobacco breaks with fitness breaks to relieve workplace stress and support the culture of fitness, expanding the use of pharmacologic stimulants to replace tobacco when used to maintain alertness, and gathering social support for tobacco cessation from non-healthcare unit members. Further study is needed to elucidate the effectiveness of proposed interventions suggested by our findings, with the ultimate aim of policy changes within the military to optimize health and military readiness, while decreasing long-term health effects and costs of tobacco use.

Taking Charge: Moving from Peer to Supervisor.

Leadership transitions occur frequently, and these times can be challenging for the individual and those they lead. Leaders must develop new knowledge and skills required of the position. Leaders also assume a new formal leadership role over prior peers. This can be a difficult task for junior leaders. The following article illustrates an example case faced by a junior Navy Medical Corps Officer and how one might respond.
