ER Rapid Diagnostic Reasoning
Generate differential diagnoses and triage reasoning in emergency medicine cases within 2-3 minutes
What You Can Do
You can rapidly generate organized differential diagnoses for undifferentiated presentations (chest pain, dyspnea, altered mental status, abdominal pain) while catching cognitive biases like anchoring and premature closure. The framework helps you articulate defensible clinical reasoning, prioritize high-acuity diagnoses, and organize your thinking during time-pressured encounters with incomplete information.
Features
captures high-acuity diagnoses alongside likely etiologies within 2-3 minutes
identifies anchoring, availability bias, and premature closure in your reasoning
separates life threats, serious conditions, and common presentations by priority
suggests directed history, exam findings, and initial testing to rule in/out top hypotheses
structures reasoning for resident education and medical-legal clarity
generates hypotheses when labs/imaging are pending
handles complex cases with multiple comorbidities and atypical presentations
Example Output
Input: 55-year-old male with acute substernal chest pain, diaphoresis, no prior cardiac history, EKG pending
Output:
HIGH ACUITY (Rule out first):
- Acute coronary syndrome (STEMI/NSTEMI) — substernal, diaphoretic, risk factors
- Aortic dissection — sudden onset, can mimic ACS
- Pulmonary embolism — dyspnea possible, immobility risk
SERIOUS (Do not miss):
- Unstable angina — ischemia without infarction
- Myocarditis/pericarditis — viral prodrome, pleuritic features
COMMON:
- Musculoskeletal pain — reproducibility on exam
- Anxiety/panic — rule-outs first
BIAS CHECK: Anchoring on "chest pain = ACS" — ensure respiratory/vascular etiologies considered
NEXT STEPS: Serial troponins, repeat EKG in 10 min, CXR for widened mediastinum, consider CT angiography based on PE risk stratification
What's Included
- SKILL.md instruction file with structured reasoning framework:
- Chief complaint-specific differential templates (chest pain, dyspnea, altered mental status, abdominal pain):
- Cognitive bias checklist for emergency medicine (anchoring, availability, premature closure):
- Acuity stratification worksheet (life threats vs. serious vs. common):
- Workup prioritization guide with directed questions and exam findings:
Who It's For
- Emergency medicine physicians and residents — accelerate differential generation and catch diagnostic gaps
- Hospitalists evaluating acute undifferentiated presentations — organize thinking when specialists unavailable
- Urgent care providers managing moderate-acuity cases — structure reasoning without full ED resources
- Medical educators and residency faculty — teach diagnostic reasoning and bias recognition
- Clinical decision-makers in time-pressured settings — document reasoning for medical-legal protection
Best For
- Undifferentiated chief complaints (chest pain, dyspnea, altered mental status, abdominal pain, syncope)
- Complex cases with multiple comorbidities and atypical presentations
- Situations with incomplete initial data (labs/imaging pending) requiring early hypothesis generation
- Cases where cognitive bias mitigation improves diagnostic accuracy
- Teaching rounds and group case discussions in clinical settings

Conduct comprehensive sports injury assessments using standardized orthopedic tests, mechanism-of-injury analysis, and functional capacity evaluation. You'll document findings in insurance-compliant formats, identify red flags requiring referral, establish objective baseline measurements for progress tracking, and generate evidence-based return-to-play recommendations with clear functional milestones.

This skill guides you through structured psychiatric case formulation using a biopsychosocial framework. You input patient presentation, assessment data, and clinical history, then receive a comprehensive formulation that integrates symptom synthesis, differential diagnosis reasoning, predisposing/precipitating/perpetuating factors, protective factors, and evidence-based treatment recommendations. The output is suitable for clinical documentation, insurance authorizations, case conferences, and supervision.

You can rapidly synthesize complex patient data—comorbidities, functional status, labs, medications—into a comprehensive risk profile and actionable optimization plan. This skill guides you through ASA classification, procedure-specific risk stratification, and patient-centered consent documentation to ensure thorough clinical reasoning and defensible preoperative assessment.

This skill examines three critical domains of your hiring process: job posting language (gendered terms, credential inflation, ableist language), pipeline diversity metrics (representation gaps at each funnel stage), and hiring structure (screening criteria, interview design, decision frameworks). You'll surface bias patterns that discourage qualified candidates and receive concrete recommendations to redesign postings, sourcing channels, and processes for greater equity.

You synthesize current clinical evidence into structured protocols tailored to your specialty and institutional context. This skill helps you build physician-nurse collaborative decision frameworks, identify implementation barriers before rollout, and create adoption guides that account for resource constraints and stakeholder buy-in. You'll develop protocols ready for medical staff committees and bedside teams—not generic templates, but specialty-specific standards that bridge research and practice.

You can generate complete psychosocial assessment documents that synthesize biographical information, presenting problems, mental health symptoms, social support systems, and environmental stressors into a coherent clinical narrative. The skill structures assessments to meet insurance reimbursement requirements, legal documentation standards, and clinical utility for interdisciplinary treatment planning. Each assessment incorporates the social work perspective of person-in-environment analysis, ensuring clinical decisions account for social, economic, cultural, and relational factors.

You can create comprehensive, evidence-based perioperative pain management protocols tailored to individual patient characteristics and surgical requirements. The skill assesses patient risk factors, recommends optimized multimodal analgesia regimens with specific drug selections and dosing rationales, incorporates regional techniques when appropriate, and identifies contingency plans for inadequate pain control or contraindications. This enables you to move beyond generic guidelines toward truly personalized pain management strategies that reduce opioid exposure while maintaining analgesia.
