Differential Diagnosis & Clinical Reasoning Framework for Nurse Practitioners
Build systematic differential diagnoses with evidence-based clinical reasoning for NP practice
What You Can Do
You can organize complex patient presentations into prioritized differential diagnoses using pattern recognition, epidemiologic principles, and clinical risk assessment. This skill helps you justify diagnostic testing decisions, reduce diagnostic error through systematic reasoning, and create defensible clinical documentation that demonstrates sound clinical judgment in your EHR narratives.
Features
Example Output
Example 1: Chest Pain Presentation
Chief Complaint: 35-year-old female with acute-onset left-sided chest pain, 2 hours duration
Differential Diagnosis (prioritized by risk):
- Acute coronary syndrome (ACS) — Age <40 but risk factors present; troponin/EKG needed immediately
- Pulmonary embolism (PE) — Recent travel + unilateral symptoms; D-dimer indicated
- Musculoskeletal chest wall pain — Reproducible on palpation; lowest acuity but must rule out life threats first
- Pericarditis — Positional pain, pleuritic quality; CXR/EKG support assessment
Recommended Initial Workup: EKG (stat), troponin, D-dimer, CXR, vital signs with orthostatics
Clinical Reasoning: While MSK pain is most common in this age group, the acute presentation and unilateral distribution necessitate ACS and PE exclusion before reassurance.
Example 2: Dyspnea with Comorbidities
Chief Complaint: 68-year-old male with progressive dyspnea, history of COPD and CHF
Differential Diagnosis (by acuity/risk):
- Acute decompensated heart failure — History of CHF, orthopnea, edema; BNP, EKG, CXR urgent
- COPD exacerbation — Known disease, triggers present; spirometry, ABG if severe
- Pneumonia — Fever, focal findings; CXR indicated
- Pulmonary embolism — Immobility risk; D-dimer if clinical suspicion elevated
Documentation: "Dyspnea prioritized by acuity risk given comorbidities. CHF exacerbation ranked first due to orthopnea and lower extremity edema classic for volume overload. COPD exacerbation remains differential but precipitants not typical."
What's Included
- SKILL.md instruction file with complete differential diagnosis framework and clinical reasoning methodology:
- Differential diagnosis template for organizing prioritized diagnoses by acuity, prevalence, and risk:
- Risk stratification checklist identifying high-acuity presentations requiring immediate workup versus lower-risk alternatives:
- Clinical documentation guide with language patterns for justifying diagnostic reasoning in EHR notes:
- Common complex presentations framework pre-populated examples (chest pain, dyspnea, abdominal pain, neurologic symptoms) ready for customization:
Who It's For
- Nurse Practitioners in primary care or urgent care settings managing undifferentiated patient presentations
- NP educators and faculty teaching clinical reasoning and diagnostic decision-making
- Nurse Practitioners new to independent practice building confidence in diagnostic justification
- Collaborative care teams where NPs document reasoning for physician review
- Quality improvement specialists reviewing diagnostic error or unnecessary testing patterns
Best For
- Complex or atypical patient presentations where multiple diagnoses are plausible
- High-stakes diagnostic decisions requiring documented clinical reasoning for liability or insurance purposes
- Diagnostic uncertainty cases where initial assessment may be incomplete or overlapping symptoms obscure diagnosis
- Teaching or justification scenarios explaining your diagnostic thinking to physicians or collaborators
- EHR documentation building clinical narratives that demonstrate sound clinical judgment and reduce diagnostic error

You can conduct comprehensive, real-time labor progression assessments that integrate cervical findings, descent patterns, uterine contractions, and psychosocial factors into structured clinical evaluations. The skill synthesizes complex obstetric data aligned with ACNM standards and birth center protocols, enabling you to identify prolonged labor or arrest disorders early and make informed decisions about continuing birth center support or recommending transfer before complications develop.

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 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 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 rapidly organize scattered assessment data (OTPF-4 domains, ADL/IADL observations, standardized test results) into defensible treatment plans that clearly connect functional gaps to specific interventions. This skill helps you document medical necessity for insurers, communicate functional limitations to patients and families in plain language, and design adaptive strategies with documented clinical rationale—reducing documentation time by 40-50% while ensuring compliance across any OT setting.

You can systematically evaluate surgical candidates by analyzing comorbidities, functional status, and lab/imaging results to generate evidence-based risk stratification and optimization plans. The skill helps you identify which patients need specialist input, determine pre-operative timeline feasibility, and communicate risk clearly to patients and surgical teams—reducing perioperative morbidity by targeting modifiable factors before surgery.

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 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.
