Abstract
Importance Diagnostic errors are common and cause significant morbidity. Large language models (LLMs) have shown promise in their performance on both multiple-choice and open-ended medical reasoning examinations, but it remains unknown whether the use of such tools improves diagnostic reasoning. Objective To assess the impact of the GPT-4 LLM on physicians' diagnostic reasoning compared to conventional resources. Design Multi-center, randomized clinical vignette study. Setting The study was conducted using remote video conferencing with physicians across the country and in-person participation across multiple academic medical institutions. Participants Resident and attending physicians with training in family medicine, internal medicine, or emergency medicine. Interventions Participants were randomized to access GPT-4 in addition to conventional diagnostic resources or to just conventional resources. They were allocated 60 minutes to review up to six clinical vignettes adapted from established diagnostic reasoning exams. Main Outcomes and Measures The primary outcome was diagnostic performance based on differential diagnosis accuracy, appropriateness of supporting and opposing factors, and next diagnostic evaluation steps. Secondary outcomes included time spent per case and final diagnosis. Results 50 physicians (26 attendings, 24 residents) participated, with an average of 5.2 cases completed per participant. The median diagnostic reasoning score per case was 76.3 percent (IQR 65.8 to 86.8) for the GPT-4 group and 73.7 percent (IQR 63.2 to 84.2) for the conventional resources group, with an adjusted difference of 1.6 percentage points (95% CI -4.4 to 7.6; p=0.60). The median time spent on cases for the GPT-4 group was 519 seconds (IQR 371 to 668 seconds), compared to 565 seconds (IQR 456 to 788 seconds) for the conventional resources group, with a time difference of -82 seconds (95% CI -195 to 31; p=0.20). GPT-4 alone scored 15.5 percentage points (95% CI 1.5 to 29, p=0.03) higher than the conventional resources group. Conclusions and Relevance In a clinical vignette-based study, the availability of GPT-4 to physicians as a diagnostic aid did not significantly improve clinical reasoning compared to conventional resources, although it may improve components of clinical reasoning such as efficiency. GPT-4 alone demonstrated higher performance than both physician groups, suggesting opportunities for further improvement in physician-AI collaboration in clinical practice.

Abstract
Phenomenon: Disrespectful behavior between physicians across departments can contribute to burnout, poor learning environments, and adverse patient outcomes. Approach: In this focus group study, we aimed to describe the nature and context of perceived disrespectful communication between emergency and internal medicine physicians (residents and faculty) at patient handoff. We used a constructivist approach and framework method of content analysis to conduct and analyze focus group data from 24 residents and 11 faculty members from May to December 2019 at a large academic medical center. Findings: We organized focus group results into four overarching categories related to disrespectful communication: characteristics and context (including specific phrasing that members from each department interpreted as disrespectful, effects of listener engagement/disengagement, and the tendency for communication that is not in-person to result in misunderstanding and conflict); differences across training levels (with disrespectful communication more likely when participants were at different training levels); the individual correspondent's tendency toward perceived rudeness; and negative/long-term impacts of disrespectful communication on the individual and environment (including avoidance and effects on patient care). Insights: In the context of predominantly positive descriptions of interdepartmental communication, participants described episodes of perceived disrespectful behavior that often had long-lasting, negative impacts on the quality of the learning environment and clinical work. We created a conceptual model illustrating the process and outcomes of these interactions. We make several recommendations to reduce disrespectful communication that can be applied throughout the hospital to potentially improve patient care, interdepartmental collaboration, and trainee and faculty quality of life.

Abstract
Dementia, according to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, is defined by a significant decline in 1 or more cognitive domains that interferes with a person's independence in daily activities. Mild cognitive impairment (MCI) differs from dementia in that the impairment is not sufficient to interfere with independence. For the purposes of this discussion, cognitive impairment (CI) includes both dementia and MCI. Various screening tests are available for CI. These tests ask patients to perform a series of tasks that assess 1 or more domains of cognitive function or ask a caregiver to report on the patient's abilities. A positive result on a screening test does not equate to a diagnosis of CI; rather, it should lead to additional testing to confirm the diagnosis. On review of the evidence, the U.S. Preventive Services Task Force (USPSTF) concluded in 2020 that the evidence was insufficient to assess the balance of benefits and harms of screening for CI in older adults ("I statement"). The USPSTF did clarify that although there is insufficient evidence, there may be important reasons to identify CI. In this article, 2 experts review the available evidence to answer the following questions: What screening tools are available, and how effective are they in identifying patients with CI? What interventions are available for patients found to have CI, to what extent do they improve patient outcomes, and what, if any, negative effects occur? And, would they recommend screening for CI, and why or why not?

Abstract
Colorectal cancer (CRC) is the third leading cause of cancer death for men and women in the United States, with an estimated 52 580 people expected to die in 2022. Most frequently, CRC is diagnosed among persons aged 65 to 74 years. However, among persons younger than 50 years, incidence rates have been increasing since the mid-1990s. In 2021, partially because of the rising incidence, the U.S. Preventive Services Task Force (USPSTF) recommended CRC screening for adults aged 45 to 49 years (Grade B recommendation). Options for CRC screening include stool-based and direct visualization tests. The USPSTF did not recommend a specific screening test; rather, its guidance was to select a test after a discussion with the patient. Here, a primary care physician and a gastroenterologist discuss the recommendation to begin CRC screening at age 45, review options for CRC screening, and discuss how to choose among the available options.

Abstract
INTRODUCTION Teaching on physical examination, especially evidence-based physical diagnosis, is at times lacking on general medicine rounds. We created a hospitalist faculty workshop on teaching evidence-based physical diagnosis. METHODS The workshop included a systematic approach to teaching evidence-based physical diagnosis, multiple teaching resources, and observed peer teaching. A long-term follow-up session was offered several months after the workshop. Participants completed questionnaires before and after the workshop as well as after the long-term follow-up session. RESULTS Four workshops were conducted and attended by 28 unique participants. Five hospitalists attended long-term follow-up sessions. Due to the COVID-19 pandemic, repeat sessions and long-term follow-up were limited. In paired analyses compared to preworkshop, respondents after the workshop reported a higher rate of prioritizing ( p = .008), having a systematic approach to ( p < .001), and confidence in ( p = .001) teaching evidence-based physical diagnosis. Compared to before the workshop, participants after the workshop were able to name more resources to inform teaching of evidence-based physical diagnosis ( p < .001). Informal feedback was positive. Respondents noted that the workshop could be improved by allowing more practice of the actual physical exam maneuvers and more observed teaching. DISCUSSION We created and implemented a workshop to train hospitalists in teaching evidence-based physical diagnosis. This workshop led to improvements in faculty attitudes and teaching skills. Long-term outcomes were limited by low participation due in part to the COVID-19 pandemic.

Abstract
Sickle cell disease is prevalent in large numbers of patients in the United States and has a significant global impact. Its complications span numerous organs and lead to reduced life expectancy. Acute and chronic sickle cell pain is a common cause of patient suffering. The American Society of Hematology published updated guidelines on management of acute and chronic pain from sickle cell disease in 2019. Several of the recommendations are conditional and leave specific decisions to the treating physician. These include conditional recommendations about the use of ketamine for acute pain and the initiation and discontinuation of long-term opioid therapy for chronic pain. Here, 2 hematologists discuss these guidelines and make contrasting recommendations for the management of acute and chronic pain for a patient with sickle cell disease.

Abstract
BACKGROUND Although the COVID-19 pandemic increased social isolation among hospitalised patients given isolation precautions, visitor restrictions and curtailed interactions with healthcare teams, medical students had limited opportunities for involvement in the care of inpatients. APPROACH We designed a humanistic and narrative medicine intervention to engage medical students in combating social isolation in hospitalised patients during the COVID-19 pandemic at a tertiary care teaching hospital. In our programme, medical students provided virtual social support to hospitalised patients via phone by providing assistance connecting with family members, having informal conversations and check-ins and writing up patient life narratives. EVALUATION From April 2020 to March 2021, we received 126 referrals of potentially isolated patients from inpatient medical teams. Fifty patients accepted and received our intervention, including 26 who completed life narratives. Feedback was positive, demonstrating benefit to medical students in learning about humanism and connecting with patients through their life stories. In addition, patients and medical teams felt more supported. We share key operational lessons and resources to facilitate the implementation of this intervention elsewhere. IMPLICATIONS Our intervention allows medical students to meaningfully contribute to the care of inpatients, support beleaguered inpatient teams and learn important lessons about humanism in medicine. This educational and patient care intervention holds promise in other settings, including beyond the COVID-19 pandemic.

Abstract
INTRODUCTION Patient handoffs from emergency physicians (EP) to internal medicine (IM) physicians may be complicated by conflict with the potential for adverse outcomes. The objective of this study was to identify the specific types of, and contributors to, conflict between EPs and IM physicians in this context. METHODS We performed a qualitative focus group study using a constructivist grounded theory approach involving emergency medicine (EM) and IM residents and faculty at a large academic medical center. Focus groups assessed perspectives and experiences of EP/IM physician interactions related to patient handoffs. We interpreted data with the matrix analytic method. RESULTS From May to December 2019, 24 residents (IM = 11, EM = 13) and 11 faculty (IM = 6, EM = 5) from the two departments participated in eight focus groups and two interviews. Two key themes emerged: 1) disagreements about disposition (ie, whether a patient needed to be admitted, should go to an intensive care unit, or required additional testing before transfer to the floor); and 2) contextual factors (ie, the request to discuss an admission being a primer for conflict; lack of knowledge of the other person and their workflow; high clinical workload and volume; and different interdepartmental perspectives on the benefits of a rapid emergency department workflow). CONCLUSIONS Causes of conflict at patient handover between EPs and IM physicians are related primarily to disposition concerns and contextual factors. Using theoretical models of task, process, and relationship conflict, we suggest recommendations to improve the EM/IM interaction to potentially reduce conflict and advance patient care.

Abstract
Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of death in the United States. Reducing ASCVD risk through primary prevention strategies has been shown to be effective; however, the role of aspirin in primary prevention remains unclear. The decision to recommend aspirin has been limited by the difficulty clinicians and patients face when trying to balance benefits and harms. In 2016, the U.S. Preventive Services Task Force addressed this issue by determining the risk level at which prophylactic aspirin generally becomes more favorable, recommending aspirin above a risk cut point (>10% estimated ASCVD risk). In 2019, the American College of Cardiology and the American Heart Association issued a guideline on the primary prevention of CVD that recommends low-dose aspirin might be considered for the primary prevention of ASCVD among select adults aged 40 to 70 years who are at higher ASCVD risk but not at increased risk for bleeding. Here, 2 experts discuss how to apply this guideline in general and to a patient in particular while answering the following questions: How do you assess ASCVD risk, and what is the role, if any, of the coronary artery calcium score?; At what risk threshold of benefits and harms would you recommend aspirin or not?; and How do you help a patient come to a decision about starting or stopping aspirin therapy?

Abstract
Nonvariceal upper gastrointestinal bleeding is common, morbid, and potentially fatal. Cornerstones of inpatient management include fluid resuscitation; blood transfusion; endoscopy; and initiation of proton-pump inhibitor therapy, which continues in an individualized manner based on risk factors for recurrent bleeding in the outpatient setting. The International Consensus Group released guidelines on the management of nonvariceal upper gastrointestinal bleeding in 2019. These guidelines provide a helpful, evidence-based roadmap for management of gastrointestinal bleeding but leave certain management details to the discretion of the treating physician. Here, 2 gastroenterologists consider the care of a patient with nonvariceal upper gastrointestinal bleeding from a peptic ulcer, specifically debating approaches to blood transfusion and endoscopy timing in the hospital, as well as the recommended duration of proton-pump inhibitor therapy after discharge.

Abstract
A 34-year-old woman is admitted to the hospital with dyspnoea, dry cough and left-sided flank pain. Her Legionella urinary test was positive and CT imaging demonstrated multifocal pneumonia with pulmonary abscesses. Although she had initial clinical improvement on appropriate antibiotic therapy, her hospital course was complicated by worsening flank pain, hypoxemia and leucocytosis, prompting clinical re-evaluation and assessment for development of complications involving the pleural space. CT imaging revealed interval development of a loculated complicated parapneumonic effusion. Successful treatment required chest tube drainage assisted by fibrinolytic therapy. This case highlights the importance of considering Legionella in patients with pulmonary abscess, demonstrates an approach to a patient with a non-resolving pneumonia and illustrates the management of parapneumonic effusions.

Abstract
Because pancreatic cancer is typically advanced at the time of diagnosis, it has a very low 5-year survival rate and may become the second leading cause of cancer death in the United States. A screening program to find early-stage pancreatic cancer is needed but has been challenging to develop because of the lack of an effective screening test. In 2019, the U.S. Preventive Services Task Force performed an evidence review and updated its guidance, confirming its 2004 "D" recommendation against routine screening for average-risk patients. Here, 2 experts review the updated guideline and recent evidence and discuss whether a patient with a family history of pancreatic cancer should undergo screening.

Abstract
About 15% of adults in the United States-37 million persons-have chronic kidney disease (CKD). Chronic kidney disease is divided into 5 groups, ranging from stage 1 to stage 5 CKD, whereas end-stage kidney disease (ESKD) is defined as permanent kidney failure. The treatment options for ESKD are kidney replacement therapy (KRT) and conservative management. The options for KRT include hemodialysis (either in-center or at home), peritoneal dialysis, and kidney transplant. Conservative management, a multidisciplinary model of care for patients with stage 5 CKD who want to avoid dialysis, is guided by patient values, preferences, and goals, with a focus on quality of life and symptom management. In 2015, the Kidney Disease Outcomes Quality Initiative recommended that patients with an estimated glomerular filtration rate below 30 mL/min/1.73 m2 be educated about options for both KRT and conservative management. In 2018, the National Institute for Health and Care Excellence recommended that assessment for KRT or conservative management start at least 1 year before the need for therapy. It also recommended that in choosing a management approach, predicted quality of life, predicted life expectancy, patient preferences, and other patient factors be considered, because little difference in outcomes has been found among options. Here, 2 experts-a nephrologist and a general internist-palliative care physician-reflect on the care of a patient with advanced CKD and mild to moderate dementia. They discuss the management options for patients with advanced CKD, the pros and cons of each method, and how to help a patient choose among the options.

Abstract
Venous thromboembolism (VTE), which includes both deep venous thrombosis and pulmonary embolism, is a common and potentially fatal condition. Medical inpatients are at high risk for VTE because of immobility as well as acute and chronic illness. Several randomized trials demonstrated that chemoprophylaxis, or low-dose anticoagulation, prevents VTE in selected medical inpatients. The 2018 American Society of Hematology clinical practice guideline on prophylaxis for hospitalized and nonhospitalized medical patients conditionally recommends chemoprophylaxis for non-critically ill medical inpatients, leaving much to the discretion of the treating physician. Here, 2 experts, a hematologist and a hospitalist, reflect on the care of a woman hospitalized with a rheumatologic disorder. They consider the risks and benefits of chemoprophylaxis, discuss VTE risk stratification, and recommend which patients should receive chemoprophylaxis and with which agents.

Abstract
OBJECTIVES To assess a community health worker (CHW) program's impact on childhood illness treatment in rural Liberia. METHODS We deployed CHWs in half of Rivercess County in August 2015 with the other half constituting a comparison group until July 2016. All CHWs were provided cash incentives, supply chain support, and monthly clinical supervision. We conducted stratified cluster-sample population-based surveys at baseline (March-April 2015) and follow-up (April-June 2016) and performed a difference-in-differences analysis, adjusted by inverse probability of treatment weighting, to assess changes in treatment of fever, diarrhea, and acute respiratory infection by a qualified provider. RESULTS We estimated a childhood treatment difference-in-differences of 56.4 percentage points (95% confidence interval [CI] = 36.4, 76.3). At follow-up, CHWs provided 57.6% (95% CI = 42.8, 71.2) of treatment in the intervention group. The difference-in-differences diarrhea oral rehydration therapy was 22.4 percentage points (95% CI = -0.7, 45.5). CONCLUSIONS Implementation of a CHW program in Rivercess County, Liberia, was associated with large, statistically significant improvements treatment by a qualified provider; however, improvements in correct diarrhea treatment were lower than improvements in coverage. Findings from this study offer support for expansion of Liberia's new National Community Health Assistant Program.

Tuberculosis infection control in a high drug-resistance setting in rural South Africa: information, motivation, and behavioral skills. J Infect Public Health 2012; 5:67-81. [PMID: 22341846 DOI: 10.1016/j.jiph.2011.10.008] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2011] [Revised: 08/22/2011] [Accepted: 10/21/2011] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Tuberculosis (TB) is transmitted in resource-limited facilities where TB infection control (IC) is poorly implemented. Theory-based behavioral models can potentially improve IC practices. METHODS The present study used an anonymous questionnaire to assess healthcare worker (HCW) TB IC information, motivation, and behavioral skills (IMB) and implementation in two resource-limited rural South African hospitals with prevalent drug-resistant TB. RESULTS Between June and August 2010, 198 surveys were completed. Although the respondents demonstrated information proficiency and positive motivation, 22.8% did not consider TB IC to be worthwhile. Most tasks were rated as easy by survey participants, but responding HCWs highlighted challenges in discrete behavioral skills. The majority of responding HCWs reported that they always wore respirators (54.3%), instructed patients on cough hygiene (63.0%), and ensured natural ventilation (67.4%) in high-risk areas. Most respondents (74.0%) knew their HIV status. Social support items correlated with the implementation of the first three aforementioned practices but not with the respondents' knowledge of their HIV status. In most cases, motivation and behavioral skills, but not information, were associated with implementation. CONCLUSION HCWs in rural South African hospitals with high drug-resistance demonstrated moderate IMB and implementation of TB IC. Improvement efforts should emphasize the development of HCW motivation and behavioral skills as well as social support from colleagues and supervisors. Such interventions should be informed by baseline IMB assessments. In the present study, a trimmed/modified IMB model helped characterize TB IC implementation.

Tuberculosis infection control in rural South Africa: survey of knowledge, attitude and practice in hospital staff. J Hosp Infect 2011; 79:333-8. [PMID: 21978608 DOI: 10.1016/j.jhin.2011.06.017] [Citation(s) in RCA: 55] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2010] [Accepted: 06/07/2011] [Indexed: 10/17/2022]
Abstract
A baseline assessment of tuberculosis infection control (TB IC) knowledge, attitude and practice (KAP) was conducted among staff in a resource-limited rural South African hospital where nosocomially transmitted multi- and extensively drug-resistant (M/XDR) TB had been reported. Assessment consisted of anonymous questionnaires and direct observation during July-September 2007, soon after the report of M/XDR-TB. Data were obtained from 57 questionnaires and 10h of direct observation. While knowledge and attitudes were generally supportive of TB IC implementation, 49.1% of staff felt that the hospital did not care about them and/or was not working to prevent staff TB infections, and 42.9% were less willing to continue as a healthcare worker because of staff TB/MDR-TB/XDR-TB deaths. Practices were variable. The recent appointment of an IC officer and implementation of natural ventilation were strengths, but the facility lacked a TB IC policy, the patient TB screening process was inadequate, and 41.5% of respondents were unaware of their personal human immunodeficiency virus (HIV) status. Respondents reported a number of barriers to TB IC implementation such as concerns about the confidentiality of staff health information, the stigma of TB and HIV, inadequate resources, and patient non-compliance. Assessment of staff KAP provided useful data regarding deficits and barriers to TB IC, and helped to focus subsequent IC strategies. Given the critical importance of reducing nosocomial TB transmission, it is recommended that facilities should conduct simplified TB IC assessment, ensure the confidentiality of staff health information, address the stigma of TB/HIV, and implement multi-faceted TB IC facility and behavioural change interventions. Behavioural science methods have the potential to improve TB IC research and implementation.
