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 conduct comprehensive pre-operative risk stratification using ASA classification, Revised Cardiac Risk Index (RCRI), and procedure-specific risk tools to quantify operative risk across physiologic systems. You systematically identify modifiable risk factors—anemia, hypertension, glucose dyscontrol, cardiac dysfunction—and implement targeted optimization protocols to reduce preventable complications. You generate objective, evidence-backed assessments that strengthen informed consent discussions, support case selection decisions, and create defensible documentation for shared decision-making with patients and surgical teams.

You'll systematically evaluate patient risk factors, stratify perioperative risk using evidence-based frameworks, and generate detailed anesthesia plans that address specific comorbidities and procedural requirements. This skill helps you synthesize complex patient data—medical history, physical exam findings, lab work, imaging, and medication profiles—into actionable risk mitigation strategies that optimize patient safety and guide technique selection, drug choices, and monitoring protocols.

You can rapidly develop theoretically-grounded case formulations that integrate diagnostic findings, historical context, and clinical observations into a coherent narrative. The skill systematizes your conceptualization across multiple therapeutic modalities (CBT, psychodynamic, trauma-informed, systemic) and generates structured treatment plans with specific goals, interventions, and prognostic considerations—ideal for supervision presentations, case conferences, documentation, and complex diagnostic scenarios.

You can systematically document refraction findings for low vision patients and generate prescriptions optimized for specific functional tasks like reading, mobility, and facial recognition. The skill calculates appropriate magnification ratios, predicts realistic visual outcomes, and creates comprehensive documentation that prioritizes quality of life over distance acuity—transforming conventional refraction into patient-centered, task-driven prescriptions.

You can rapidly analyze multifaceted surgical presentations—including revision cases, comorbidities, and combined pathology—to develop defensible pre-operative plans and detailed operative notes. The skill synthesizes clinical findings with imaging data, stratifies surgical risk, selects technique-specific approaches, and produces documentation that withstands peer review and quality audits.

You can perform structured sports injury evaluations that incorporate mechanism-of-injury analysis, orthopedic special testing, functional movement screening, and clear referral criteria. The skill helps you differentiate soft tissue restrictions from joint dysfunctions, establish baseline function, and create evidence-based return-to-play milestones tailored to the athlete's sport and position. You'll generate documentation suitable for insurance records, team physician communication, and liability protection.

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 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.
