Differential Diagnosis Framework for Nurse Practitioners
Build systematic differential diagnoses with evidence-based clinical reasoning
What You Can Do
You'll develop comprehensive, hierarchical differential diagnoses that integrate clinical reasoning principles with patient safety. This framework helps you identify 'can't-miss' diagnoses, challenge diagnostic assumptions, and sequence diagnostic workup logically—whether managing complex presentations, atypical symptoms, or high-stakes clinical decisions in primary care, urgent care, or specialty settings.
Features
Organize differential diagnoses by likelihood and clinical urgency rather than relying on pattern recognition alone
Identify and prioritize critical 'can't-miss' diagnoses that could cause serious harm if missed
Apply evidence-based diagnostic frameworks used in medical education to structure your thinking
Challenge implicit biases and ensure rare but serious conditions receive consideration
Determine appropriate test ordering and timing based on clinical probability and patient safety
Navigate complex presentations where multiple conditions confound the clinical picture
Justify diagnostic test ordering and clinical decisions for medical records and peer review
Example Output
Input: Patient presents with 6 weeks of progressive dyspnea, fatigue, and lower extremity edema in a 58-year-old with hypertension and prediabetes.
Output:
Primary Diagnostic Considerations:
- Heart failure (systolic or diastolic) — Most likely; fits symptom timeline, comorbidities, and presentation
- Chronic kidney disease with secondary HTN — Edema pattern suggests volume overload; proteinuria screening needed
- Thyroid dysfunction (hypothyroidism) — Fatigue + edema; less likely but easily ruled out
Can't-Miss Diagnoses:
- Acute coronary syndrome with heart failure — Atypical dyspnea presentation; ECG and troponin mandatory
- Pulmonary embolism — Progressive dyspnea warrants D-dimer risk stratification
- Acute decompensated renal failure — Edema location and pattern suggest fluid retention
Recommended Workup Sequence: ✓ Labs: BNP, troponin, CBC, CMP, TSH, urinalysis ✓ Imaging: Chest X-ray (initial assessment), echocardiogram if BNP elevated ✓ ECG: Baseline; assess for ischemic changes
What's Included
- SKILL.md instruction file with framework overview and usage guidelines:
- Differential Diagnosis Template: Structured worksheet for organizing diagnostic hierarchies
- Risk Stratification Checklist: Identifying and prioritizing can't-miss diagnoses
- Clinical Reasoning Worksheet: Documenting assumptions, biases, and diagnostic logic
- Diagnostic Workup Priority Guide: Test sequencing and ordering rationale by clinical scenario
Who It's For
- Nurse practitioners in primary care, urgent care, and specialty practices managing complex presentations
- Clinical educators teaching diagnostic reasoning to NP students, residents, and PAs
- Experienced NPs seeking second opinions or systematic review of atypical cases
- NPs transitioning to new specialties requiring structured diagnostic frameworks
- Healthcare teams developing differential diagnoses collaboratively in case consultations
Best For
- Complex presentations with multiple overlapping symptoms and comorbidities
- Atypical or ambiguous clinical presentations resistant to pattern recognition
- High-stakes diagnostic decisions (chest pain, acute neurological changes, acute abdominal pain)
- Rare diagnosis consideration when patients aren't responding to expected treatment
- Diagnostic test ordering justification and documentation for medical records
You might also like
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.

You can systematically analyze complex oral surgical cases by generating comprehensive pre-operative plans that consider osseous anatomy, neurovascular structures, and patient-specific risk factors. Claude structures multifactorial surgical analysis into actionable operative protocols, risk stratification reports, and detailed procedural workflows that reduce surgical time and improve clinical outcomes while providing medical-legal documentation.

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.

This skill transforms fragmented OT assessment findings—ROM measurements, strength tests, ADL observations—into cohesive clinical narratives that connect impairment to functional limitation to participation restriction. You'll generate SMART goals that satisfy both clinical rigor and insurance reimbursement standards, and build intervention plans with explicit evidence-based rationale that accelerates authorization and justifies medical necessity to payers.
