Seriously ill hospitalized patients have identified communication and decision making about goals of care as high priorities for quality improvement in end-of-life care. Interventions to improve are more likely succeed if tailored existing barriers.To determine, from the perspective hospital-based clinicians, (1) barriers impeding with seriously their families (2) own willingness acceptability other clinicians engage this process.Multicenter survey medical teaching units nurses, internal...

Medical Education 2012: 46: 1055–1062 CONTEXT Simulation training has emerged as an effective way to complement clinical of medical students. Yet outcomes from simulation must be considered suboptimal when 25–30% students fail recognise a cardiac murmur on which they were trained 1 hour previously. There are several possible explanations for failure improve following training, include the impact heightened emotions learning and cognitive overload caused by interactivity with high-fidelity...

Medical Education 2012: 46: 648–656 Objectives Simulation training offers opportunities for unsupervised, self‐regulated learning, yet little evidence is available to indicate the efficacy of this approach in learning procedural skills. We evaluated effectiveness directed (DSRL) and instructor‐regulated (IRL), respectively, teaching lumbar puncture (LP) using simulation. Methods randomly assigned internal medicine residents postgraduate year 1 either DSRL (‘directed’ progress from easy...

Bedside point-of-care ultrasound (POCUS) is increasingly used to assess medical patients. At present, no consensus exists for what POCUS curriculum appropriate internal medicine residency training programs. This document details the consensus-based recommendations by Canadian Internal Medicine Ultrasound (CIMUS) group, comprising 39 members, representing 14 institutions across Canada. Guiding principles selecting curricular content were determined a priori. Consensus was defined as agreement...

Abstract Background Point-of-care ultrasound (POCUS) is increasingly used in internal medicine, but a lack of trained faculty continues to limit the spread POCUS education. Using framework based on organizational change theories, this study sought identify barriers and enablers for hospital-based practicing internists learn use clinical practice. Methods We invited at six North American institutions participate an electronic survey their opinions regarding 39 enablers. Results Of 342...

Abstract Objectives The purpose of this study is to provide expert consensus recommendations establish a global ultrasound curriculum for undergraduate medical students. Methods 64 multi-disciplinary experts from 16 countries, 50 consultants, and 21 students residents contributed these recommendations. A modified Delphi method was used that included systematic literature search, evaluation the quality by GRADE system, RAND appropriateness panel judgment decisions. process four in-person...

Non-invasive measures that can accurately estimate cardiac output may help identify volume-responsive patients. This study seeks to compare two non-invasive (corrected carotid flow time and blood flow) their correlations with invasive reference measurements of output. Consenting adult patients (n = 51) at Massachusetts General Hospital catheterization laboratory undergoing right heart between February April 2016 were included. Carotid ultrasound images obtained concurrently measurements, by...

Concussion and mild traumatic brain injury (mTBI) research has made minimal progress diagnosing who will suffer from lingering symptomology or generating effective treatment strategies. Research demonstrates that dietary intake affects many biological systems including neurological health. This study determined if exposure to a high fat diet (HFD) caloric restriction (CR) altered post-concussion susceptibility resiliency using rodent model of pediatric concussion. Rats were maintained on...

<h3>Importance</h3> Discussions about goals of care with patients who are seriously ill typically occur infrequently and late in the illness trajectory, low quality, focus narrowly on patient's resuscitation preferences (ie, code status), risking provision that is inconsistent patients' values. The Serious Illness Care Program (SICP) a multifaceted communication intervention builds capacity for clinicians to have earlier, more frequent, person-centered conversations. <h3>Objective</h3> To...

Point-of-care ultrasound (POCUS) involves the acquisition, interpretation, and immediate clinical integration of ultrasonographic imaging performed by a treating clinician. The current state cardiac POCUS terminology is heterogeneous ambiguous, in part because it evolved through siloed specialty practices. In particular, medical literature colloquial conversation contain wide variety terms that equate to POCUS. While diverse aided development dissemination throughout multiple specialties,...
