Hospital Physicians' Stethoscopes: Bacterial Contamination After a Simple Cleaning Protocol.

BACKGROUND: Stethoscope surfaces become contaminated with bacteria due to inconsistent cleaning practices,​ as​​ ​​​​cleaning frequency and practical clean​s​ing approaches are not well-established. METHODS: We investigated bacterial contamination of stethoscopes at baseline, after simple cleaning, and after examining one patient. We surveyed 30 hospital providers on stethoscope cleaning practices and then measured bacterial contamination of stethoscope diaphragm surfaces before cleaning, after cleaning with alcohol-based hand sanitizer, and after use in examining one patient. RESULTS: Only 20% of providers reported cleaning stethoscopes regularly. Before cleaning, 50% of stethoscopes were contaminated with bacteria, compared with 0% after cleaning (p<0.001) and 36.7% after examining one patient (p=0.002). Among providers who reported not cleaning stethoscopes regularly, 58% had bacterial-contaminated stethoscopes compared with 17% who did report cleaning regularly (p=0.068). CONCLUSIONS: Hospital providers' stethoscopes had a high probability of bacterial contamination at baseline and after examining one patient. We recommend decontamination with alcohol-based hand sanitizer immediately before each patient examination.

A Case of Concurrent Mpox and Chlamydial Proctitis in a Patient With HIV.

The monkeypox (mpox) outbreak that began in May 2022 spread globally with a wide range of presentations. Mpox proctitis has been recognized as one of the severe forms of the virus during this outbreak. We present the case of a 33-year-old male with well-controlled HIV engaging in receptive anal intercourse presented with profuse rectal bleeding, tenesmus, and anal pain in July 2022. His symptoms persisted despite treatment for his rectal chlamydia with doxycycline. Rectal imaging with computed tomography demonstrated impressive inflammation. Contrast-enhanced images highlighted rectal wall thickening and submucosal edema. Diffuse lymphadenopathy of the anorectal region was also clearly seen. He received symptomatic treatment with tecovirimat resulting in the resolution of his symptoms and complaints. Subsequent rectal imaging displayed improvement and decreased inflammation. A better understanding of various presentations, imaging characteristics, and management is necessary to curb further dissemination.

Clinical Case-Conference Blogs: Integrating Clinical Librarians to Enhance Resident Education and Enforce ACGME Competencies.

Resident conferences are primary educational endeavors for trainees and faculty alike. We describe the development of collaborative clinician-librarian educational blogs within the Internal Medicine (2009), Pediatrics (2012), and General Surgery (2018) residency programs. Clinical librarians attended resident conferences and generated evidence-based blog posts based on learning topics and clinical questions encountered during the conferences. In the decade since introduction of the blogs, this partnership has resulted in over 2000 blog posts and generated over 1800 individual views per month. The development of a clinical librarian-managed blog serves as a relevant resource for promoting evidence-based practices within a case-based learning curriculum, engages interdisciplinary collaboration through existing resources, and is generalizable across various clinical practice disciplines and trainees.

Here's the rub: A case of constrictive pericarditis in an adult with cystic fibrosis.

We present a rare coexistence of constrictive pericarditis in a patient with cystic fibrosis. Careful attention to cardiac friction rub auscultated on initial examination prompted echocardiography revealing constrictive pericarditis further confirmed by cardiac magnetic resonance imaging that allowed for dedicated treatment in addition to management of his concurrent respiratory infection.

Practical Evidence-Based Medicine at the Student-to-Physician Transition: Effectiveness of an Undergraduate Medical Education Capstone Course.

INTRODUCTION: Medical information is expanding at exponential rates. Practicing physicians must acquire skills to efficiently navigate large bodies of evidence to answer clinical questions daily. How best to prepare medical students to meet this challenge remains unknown. The authors sought to design, implement, and assess a pragmatic evidence-based medicine (EBM) course engaging students at the transition from undergraduate to graduate medical education. MATERIALS AND METHODS: An elective course was offered during the required 1-month Capstone medical school curriculum. Participants included one hundred sixty-eight graduating fourth-year medical students at Emory University School of Medicine who completed the course from 2012 to 2018. Through interactive didactics, small groups, and independent work, students actively employed various electronic tools to navigate medical literature and engaged in structured critical appraisal of guidelines and meta-analyses to answer clinical questions. RESULTS: Assessment data was available for 161 of the 168 participants (95.8%). Pre- and post-assessments demonstrated students' significant improvement in perceived and demonstrated EBM knowledge and skills (p < 0.001), consistent across gender and specialty subgroups. DISCUSSION: The Capstone EBM course empowered graduating medical students to comfortably navigate electronic medical resources and accurately appraise summary literature. The objective improvement in knowledge, the perceived improvement in skill, and the subjective comments support this curricular approach to effectively prepare graduating students for pragmatic practice-based learning as resident physicians.

A novel helmet-mounted device for reducing the potential of catastrophic cervical spine fractures and spinal cord injuries in head-first impacts.

BACKGROUND: Head-first impacts with an aligned cervical spine cause some of the most severe types of injuries due to the risk of fractures and associated spinal cord injury. Sports, such as football, mountain biking and horseback riding, contribute to the incidence of spinal cord injury but there is potential to reduce the risk of these injuries through a helmet-mounted device. METHODS: A novel device, the Pro-Neck-Tor mechanism, was incorporated into a commercial football helmet and tested in head-first impact experiments. The Pro-Neck-Tor connects an inner and outer helmet shell, which upon head-first impact of a certain load, induces motion of the head away from the path of the following torso. Impacts were performed onto three impact surface angles with a flexion-inducing Pro-Neck-Tor mechanism. FINDINGS: Based on averaged data, the Pro-Neck-Tor provided a significant and consistent reduction in peak compressive neck forces compared to the unmodified football helmet in the conditions tested. In some impact conditions, the Pro-Neck-Tor increased the peak sagittal plane neck bending moments and impulse over that observed for the unmodified helmet. INTERPRETATION: The Pro-Neck-Tor with flexion escape is capable of lowering axial neck forces in head-first impacts compared to a conventional helmet by guiding the cervical column away from an aligned posture and into an eccentric loading scenario which published studies suggests frequently leads to no injury or to a less severe injury. Continued development and testing of the device are needed to optimize the altered neck loading and to drive the design toward a commercial configuration.

Efficiently finding and using evidence to guide clinical practice and improve care.

Using evidence to guide patient care improves patient outcomes. However, the volume of clinical and scientific literature and demands on provider time make staying current challenging. Primary literature searching or using public search engines to answer clinical questions often results in low-quality or incorrect answers, potentially yielding suboptimal clinical care. This article describes systematic strategies for primary literature searching that can yield higher-quality results than an unstructured approach.

Reorganizing a hospital ward as an accountable care unit.

Traditional hospital wards are not specifically designed as effective clinical microsystems. The feasibility and sustainability of doing so are unclear, as are the possible outcomes. To reorganize a traditional hospital ward with the traits of an effective clinical microsystem, we designed it to have 4 specific features: (1) unit-based teams, (2) structured interdisciplinary bedside rounds, (3) unit-level performance reporting, and (4) unit-level nurse and physician coleadership. We called this type of unit an accountable care unit (ACU). In this narrative article, we describe our experience implementing each feature of the ACU. Our aim was to introduce a progressive approach to hospital care and training.

Evaluating Simulation-Based ACLS Education on Patient Outcomes: A Randomized, Controlled Pilot Study.

BACKGROUND: Simulation training is widely accepted as an effective teaching tool, especially for dealing with high-risk situations. OBJECTIVE: We assessed whether standardized, simulation-based advanced cardiac life support (ACLS) training improved performance in managing simulated and actual cardiac arrests. METHODS: A total of 103 second- and third-year internal medicine residents were randomized to 2 groups. The first group underwent conventional ACLS training. The second group underwent two 2 1/2-hour sessions of standardized simulation ACLS teaching. The groups were assessed by evaluators blinded to their assignment during in-hospital monthly mock codes and actual inpatient code sheets at 3 large academic hospitals. Primary outcomes were time to initiation of cardiopulmonary resuscitation, time to administration of first epinephrine/vasopressin, time to delivery of first defibrillation, and adherence to American Heart Association guidelines. RESULTS: There were no differences in primary outcomes among the study arms and hospital sites. During 21 mock codes, the most common error was misidentification of the initial rhythm (67% [6 of 9] and 58% [7 of 12] control and simulation arms, respectively, P  =  .70). There were no differences in primary outcome among groups in 147 actual inpatient codes. CONCLUSIONS: This blinded, randomized study found no effect on primary outcomes. A notable finding was the percentage of internal medicine residents who misidentified cardiac arrest rhythms.

Bicycle helmets are highly effective at preventing head injury during head impact: head-form accelerations and injury criteria for helmeted and unhelmeted impacts.

Cycling is a popular form of recreation and method of commuting with clear health benefits. However, cycling is not without risk. In Canada, cycling injuries are more common than in any other summer sport; and according to the US National Highway and Traffic Safety Administration, 52,000 cyclists were injured in the US in 2010. Head injuries account for approximately two-thirds of hospital admissions and three-quarters of fatal injuries among injured cyclists. In many jurisdictions and across all age levels, helmets have been adopted to mitigate risk of serious head injuries among cyclists and the majority of epidemiological literature suggests that helmets effectively reduce risk of injury. Critics have raised questions over the actual efficacy of helmets by pointing to weaknesses in existing helmet epidemiology including selection bias and lack of appropriate control for the type of impact sustained by the cyclist and the severity of the head impact. These criticisms demonstrate the difficulty in conducting epidemiology studies that will be regarded as definitive and the need for complementary biomechanical studies where confounding factors can be adequately controlled. In the bicycle helmet context, there is a paucity of biomechanical data comparing helmeted to unhelmeted head impacts and, to our knowledge, there is no data of this type available with contemporary helmets. In this research, our objective was to perform biomechanical testing of paired helmeted and unhelmeted head impacts using a validated anthropomorphic test headform and a range of drop heights between 0.5m and 3.0m, while measuring headform acceleration and Head Injury Criterion (HIC). In the 2m (6.3m/s) drops, the middle of our drop height range, the helmet reduced peak accelerations from 824g (unhelmeted) to 181g (helmeted) and HIC was reduced from 9667 (unhelmeted) to 1250 (helmeted). At realistic impact speeds of 5.4m/s (1.5m drop) and 6.3m/s (2.0m drop), bicycle helmets changed the probability of severe brain injury from extremely likely (99.9% risk at both 5.4 and 6.3m/s) to unlikely (9.3% and 30.6% risk at 1.5m and 2.0m drops respectively). These biomechanical results for acceleration and HIC, and the corresponding results for reduced risk of severe brain injury show that contemporary bicycle helmets are highly effective at reducing head injury metrics and the risk for severe brain injury in head impacts characteristic of bicycle crashes.

Avoiding handover fumbles: a controlled trial of a structured handover tool versus traditional handover methods.

BACKGROUND: Handover of patient information represents a critical time period during a patient's hospitalisation. While recent guidelines promote standardised communication during these patient care transitions, significant variability in structure and practice persists among hospitals and providers. METHODS: The authors surveyed internal medicine residents regarding handover practices before and after introduction of a structured, web-based handover application. The handover application standardised patient data in a format suitable for both patient handovers and day-to-day patient management. RESULTS: A total of 80 residents were surveyed prior to the intervention (80% response rate) and 161 residents during the intervention (average 68% response rate for all surveys distributed). At baseline, residents perceived deficits in handover practices related to the variability of information transferred and correlated that variability to near-miss events. After introduction of the handover application, 100% of handovers contained an updated problem list, active medications, and code status (compared to <55% at baseline, p<0.01); residents perceived approximately half as many near-miss events on call (31.5% vs 55%; p=0.0341) and were twice as likely to respond that they were confident or very confident in their patient handovers compared to traditional practices (93% vs 49%; p=0.01). CONCLUSION: Standardisation of information transmitted during patient handovers through the use of a structured, web-based application led to consistent transfer of vital patient information and was associated with improved resident confidence and fewer perceived near-miss events on call.

Temporary central venous catheter utilization patterns in a large tertiary care center: tracking the "idle central venous catheter".

OBJECTIVES: Although central venous catheter (CVC) dwell time is a major risk factor for catheter-related bloodstream infections (CR-BSIs), few studies reveal how often CVCs are retained when not needed ("idle"). We describe use patterns for temporary CVCs, including peripherally inserted central catheters (PICCs), on non-ICU wards. DESIGN: A retrospective observational study. SETTING: A 579-bed acute care, academic tertiary care facility. METHODS: A retrospective observational study of a random sample of patients on hospital wards who have a temporary, nonimplanted CVC, with a focus on on daily ward CVC justification. A uniform definition of idle CVC-days was used. RESULTS: We analyzed 89 patients with 146 CVCs (56% of which were PICCs); of 1,433 ward CVC-days, 361 (25.2%) were idle. At least 1 idle day was observed for 63% of patients. Patients had a mean of 4.1 idle days and a mean of 3.4 days with both a CVC and a peripheral intravenous catheter (PIV). After adjusting for ward length of stay, mean CVC dwell time was 14.4 days for patients with PICCs versus 9.0 days for patients with non-PICC temporary CVCs (other CVCs; P<.001). Patients with a PICC had 5.4 days in which they also had a PIV, compared with 10 days in other CVC patients (P<.001). Patients with PICCs had more days in which the only justification for the CVC was intravenous administration of antimicrobial agents (8.5 vs 1.6 days; P=.0013). CONCLUSIONS: Significant proportions of ward CVC-days were unjustified. Reducing "idle CVC-days" and facilitating the appropriate use of PIVs may reduce CVC-days and CR-BSI risk.

Hospitalists and intensivists in the medical ICU: a prospective observational study comparing mortality and length of stay between two staffing models.

BACKGROUND: A shortage of critical care specialists or intensivists, coupled with expanding United States critical care needs, mandates identification of alternate qualified physicians for intensive care unit (ICU) staffing. OBJECTIVE: To compare mortality and length of stay (LOS) of medical ICU patients cared for by a hospitalist or an intensivist-led team. DESIGN: Prospective observational study. SETTING: Urban academic community hospital affiliated with a major regional academic university. PATIENTS: Consecutive medical patients admitted to a hospitalist ICU team (n = 828) with selective intensivist consultation or an intensivist-led ICU teaching team (n = 528). MEASUREMENTS: Endpoints were ICU and in-hospital mortality and LOS, adjusted for patient differences with logistic and linear regression models and propensity scores. RESULTS: The odds ratio adjusted for disease severity for in-hospital mortality was 0.8 (95% confidence interval [CI]: 0.49, 1.18; P = 0.23) and ICU mortality was 0.8 (95% CI: 0.51, 1.32; P = 0.41), referent to the hospitalist team. The adjusted LOS was similar between teams (hospital LOS difference 0.9 days, P = 0.98; ICU LOS difference 0.3 days, P = 0.32). Mechanically ventilated patients with intermediate illness severity had lower hospital LOS (10.6 vs 17.8 days, P < 0.001) and ICU LOS (7.2 vs 10.6 days, P = 0.02), and a trend towards decreased in-hospital mortality (15.6% vs 27.5%, P = 0.10) in the intensivist-led group. CONCLUSIONS: The adjusted mortality and LOS demonstrated no statistically significant difference between hospitalist and intensivist-led ICU models. Mechanically ventilated patients with intermediate illness severity showed improved LOS and a trend towards improved mortality when cared for by an intensivist-led ICU teaching team.

Hospitalist handoffs: a systematic review and task force recommendations.

BACKGROUND: Handoffs are ubiquitous to Hospital Medicine and are considered a vulnerable time for patient safety. PURPOSE: To develop recommendations for hospitalist handoffs during shift change and service change. DATA SOURCES: PubMed (through January 2007), Agency for Healthcare Research and Quality (AHRQ) Patient Safety Network, white papers, and hand search of article bibliographies. STUDY SELECTION: Controlled studies evaluating interventions to improve in-hospital handoffs (n = 10). DATA EXTRACTION: Studies were abstracted for design, setting, target, outcomes (including patient-level, staff-level, or system-level outcomes), and relevance to hospitalists. DATA SYNTHESIS: Although there were no studies of hospitalist handoffs, the existing literature from related disciplines and expert opinion support the use of a verbal handoff supplemented with written documentation in a structured format or technology solution. Technology solutions were associated with a reduction in preventable adverse events, improved satisfaction with handoff quality, and improved provider identification. Nursing studies demonstrate that supplementing verbal exchange with a written medium leads to improved retention of information. White papers characterized effective verbal exchange, as focusing on ill patients and actions required, with time for questions and minimal interruptions. In addition, content should be updated daily to ensure communication of the latest clinical information. Using this literature, recommendations for hospitalist handoffs are presented with corresponding levels of evidence. Recommendations were reviewed by hospitalists at the Society of Hospital Medicine (SHM) Annual Meeting and by an interdisciplinary team of expert consultants and were endorsed by the SHM governing board. CONCLUSIONS: The systematic review and resulting recommendations provide hospitalists a starting point from which to improve in-hospital handoffs.
