Emergency Differential Diagnosis & Clinical Decision Support
Rapid systematic differential diagnosis for acute presentations with red-flag prioritization
What You Can Do
Generate systematic differential diagnoses for acute clinical presentations in 2-3 minutes by mapping patient symptoms to red flags, high-risk conditions, and conditional risk stratification. Document clinical reasoning in formats that withstand peer review and legal scrutiny, ensuring you rule out life threats first while avoiding anchoring bias and premature diagnostic closure.
Features
Automatically identify dangerous conditions masked by common presentations
Rank differentials by acuity and mortality risk, not prevalence
Estimate likelihood of high-risk diagnoses given your patient's specific presentation
Generate clinical reasoning summaries that justify your workup and disposition decisions
Structured reassessment framework reduces anchoring bias and premature closure
Link each diagnosis to appropriate diagnostic tests, imaging, and disposition recommendations
Create explicit reasoning narratives for safe transitions of care
Example Output
Patient: 42M with acute chest pain, diaphoresis, 2-hour duration
Differential (by risk priority):
- Acute coronary syndrome — RED FLAG: Diaphoresis + substernal pain + male age. Likelihood: HIGH. Next: 12-lead ECG, troponin serial, aspirin 325mg, continuous cardiac monitoring.
- Pulmonary embolism — RED FLAG: Pleuritic component if present. Risk factors: Assess for DVT signs, recent immobility. Next: D-dimer or CT-PE protocol if pretest probability intermediate-high.
- Aortic dissection — RED FLAG: Sudden onset + diaphoresis. Key history: HTN, Marfan syndrome, cocaine use. Next: Chest imaging (CTA or TEE) if clinical suspicion high.
- Pneumothorax — Less likely given diaphoresis and substernal location, but examine breath sounds bilaterally.
Clinical reasoning: Diaphoresis + chest pain in 42M creates 60% pretest probability for ACS. ECG and troponin are mandatory first steps. PE remains on differential if pleuritic features or risk factors present.

You might also like
You can systematically generate ranked differential diagnoses for presenting complaints (chest pain, dyspnea, abdominal pain, headache, joint pain, fatigue) by applying evidence-based clinical decision rules and risk stratification. The skill helps you identify red flags that change management priority, justify test selection to supervising physicians, and document diagnostic reasoning in the medical record while reducing anchoring bias and ensuring comprehensive consideration of serious diagnoses.

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.

You can conduct comprehensive subluxation assessments on pediatric patients by integrating structural examination findings, functional limitations, parental observations, and neurological indicators within a developmental context. Claude helps you correlate specific subluxations to presenting complaints (colic, ear infections, torticollis, scoliosis patterns) and create objective documentation suitable for insurance, medical records, and referral purposes. You'll develop age-appropriate treatment plans that address both the subluxation and the child's unique physiological stage.

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 convert clinical observation notes, standardized assessment results (FIM, COPM, AMPAC, etc.), and patient history into professionally formatted occupational therapy functional assessment reports. The skill synthesizes raw data into cohesive narratives that document baseline function, identify specific functional limitations, justify interventions to insurance companies, and establish measurable treatment goals—reducing hours of manual documentation while ensuring compliance with insurance requirements and clinical standards.

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.
