We discuss capacity assessment, patient autonomy, safety, and documentation. Hosts: Anne Levine, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Capacity_Assessment.mp3 Download One Comment Show Notes The Importance of Capacity Assessment Arises frequently in the ED, even when not formally recognized Carries both legal implications and ethical weight Failure to appropriately assess capacity can result in: Forced treatment without justification Missed opportunities to respect autonomy Increased risk of litigation and poor patient outcomes Defining Capacity Capacity is: Decision-specific: varies based on the medical choice at hand Time-specific: can fluctuate due to medical conditions, intoxication, delirium Distinct from competency, which is a legal determination Relies on a patient’s ability to: Understand relevant information Appreciate the consequences Reason through options Communicate a clear choice Real-World ED Examples Intoxicated patient with head trauma refusing CT Unreliable neuro exam Potentially time-sensitive intracranial injury Elderly patient with sepsis refusing admission due to caregiving responsibilities Balancing autonomy vs. beneficence Patient with gangrenous diabetic foot refusing surgery Demonstrates logic and consistency despite high-risk decision The 4 Pillars of Capacity Assessment Understanding Can the patient explain: Their condition Recommended treatments Risks and benefits Alternatives and outcomes?

We dive into the recognition and management of blast crisis. Hosts: Sadakat Chowdhury, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Blast_Crisis.mp3 Download 2 Comments Tags: Hematology, Oncology Show Notes Topic Overview Blast crisis is an oncologic emergency, most commonly seen in chronic myeloid leukemia (CML). Defined by: >20% blasts in peripheral blood or bone marrow. May include extramedullary blast proliferation. Without treatment, median survival is only 3–6 months. Pathophysiology & Associated Conditions Usually occurs in CML, but also in: Myeloproliferative neoplasms (MPNs) Myelodysplastic syndromes (MDS) Transition from chronic to blast phase often reflects disease progression or treatment resistance. Risk Factors 10% of CML patients progress to blast crisis. Risk increased in: Patients refractory to tyrosine kinase inhibitors (e.g., imatinib). Those with Philadelphia chromosome abnormalities. WBC >100,000, which increases risk for leukostasis. Clinical Presentation Symptoms often stem from pancytopenia and leukostasis: Anemia: fatigue, malaise. Functional neutropenia: high WBC count, but increased infection/sepsis risk. Thrombocytopenia: bleeding, bruising. Leukostasis/hyperviscosity effects by system: Neurologic: confusion, visual changes, stroke-like symptoms. Cardiopulmonary: ARDS, myocardial injury. Others: priapism, limb ischemia, bowel infarction.

We explore the expanding field of Geriatric Emergency Medicine. Hosts: Ula Hwang, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Geriatric_Emergency_Medicine.mp3 Download Leave a Comment Tags: Geriatric Show Notes Key Topics Discussed Importance and impact of geriatric emergency departments. Optimizing care strategies for geriatric patients in ED settings. Practical approaches for non-geriatric-specific EDs. Challenges in Geriatric Emergency Care Geriatric patients often present with: Multiple chronic conditions Polypharmacy Functional decline (mobility issues, cognitive impairments, social isolation) Adapting Clinical Approach Core objective remains acute issue diagnosis and treatment. Additional considerations for geriatric patients: Review and caution with medications to prevent adverse reactions. Address functional limitations and cognitive impairments. Emphasize safe discharge and care transitions to prevent unnecessary hospitalization. Identifying High-Risk Geriatric Patients Screening tools: Identification of Seniors at Risk (ISAR) Frailty screens Alignment with the “Age-Friendly Health Systems” initiative focusing on: Mentation Mobility Medications Patient preferences (what matters most) Mistreatment (elder abuse awareness)

Leads to swelling, inflammation, and possible airway obstruction. Chemical Irritation: Causes bronchospasm, mucus plugging, and inflammation in the lower airways. Increases capillary permeability, potentially causing pulmonary edema. Systemic Toxicity: Primarily involves carbon monoxide and cyanide poisoning.

We discuss the evaluation of and treatment options for acute back pain. Hosts: Benjamin Friedman, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Acute_Back_Pain.mp3 Download Leave a Comment Tags: Musculoskeletal, Orthopaedics Show Notes **Please fill out this quick survey to help us develop additional resources for our listeners: Core EM Survey** Clinical Evaluation: Primary Goal: Distinguish benign musculoskeletal pain from serious pathology. Red Flags: Look for indicators of spinal infection, spinal bleed, or space-occupying lesions (e.g., tumors, large herniated discs). Assessment: A thorough history and neurological exam (strength testing, gait) is essential. Additional Tools: Use bedside ultrasound for post-void residual assessment in suspected cauda equina syndrome Imaging Guidelines: Routine Imaging: Generally not indicated for young, healthy patients without red flags. ACEP Recommendations: Avoid lumbar X-rays in patients under 50 without risk factors, as they do not change management and may increase costs and ED time. Advanced Imaging: Reserve MRI for patients with red flags, neurological deficits, or suspected cauda equina syndrome; CRP may be a part of your calculus when evaluating for infectious causes of back pain Treatment Options: Evidence-Based First-Line: NSAIDs offer modest benefit.

We discuss the impact of family presence during resuscitations. Hosts: Ellen Duncan, MD, PhD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Family_Presence_During_Resuscitation.mp3 Download Leave a Comment Tags: Critical Care, Pediatrics Show Notes Overview Historical Context: The conversation around allowing family members in the room during resuscitation events began gaining attention in 1987. Since then, the practice has been increasingly encouraged. Current Practices in Pediatrics: Family presence during pediatric resuscitations remains inconsistent, with healthcare provider acceptance ranging from 15% to 85%. Many subspecialists and consultants still request that families step out, often due to outdated concerns. Common Concerns & Myths: Interference in resuscitation → Studies show minimal disruption. Legal risks → No increased litigation risk has been demonstrated. Family trauma → Research suggests that presence may help with grieving and reduce PTSD symptoms. Evidence from the Literature New England Journal of Medicine study on Family Presence During Cardiopulmonary Resuscitation (Jabre et al., 2013): In a randomized controlled trial of 570 relatives, PTSD-related symptoms were significantly higher in family members who were not...

High mortality and morbidity underscore the need for vigilance. Definition A rapidly progressive, life-threatening infection of the deep soft tissues. Involves fascia and subcutaneous fat, causing fulminant tissue destruction. High mortality often due to delayed recognition and treatment. Types of Necrotizing Fasciitis Type I (Polymicrobial) Involves aerobic and anaerobic organisms (e.g., Bacteroides, Clostridium, Peptostreptococcus).
