Usage Examples

Clinical Query

$ ollama run Jayasimma/healthcare

> Patient presents with fever, cough, and shortness of breath for 3 days. What are the differential diagnoses?

Healthcare AI: Based on the presenting symptoms, the differential diagnoses include:

1. Community-Acquired Pneumonia (CAP) - Most likely given the triad of symptoms
2. Acute Bronchitis - Common, especially if viral prodrome present
3. COVID-19 - Must be considered in current epidemiological context
4. Influenza - Particularly during flu season
5. Exacerbation of underlying lung disease (COPD/Asthma)
6. Pulmonary Embolism - If risk factors present

Recommended immediate steps:
- Vital signs assessment (temperature, SpO2, respiratory rate, blood pressure)
- Chest X-ray
- Complete blood count, CRP
- COVID-19 testing
- Pulse oximetry
- Consider arterial blood gas if severe

Red flags requiring immediate attention:
- SpO2 <90%
- Respiratory rate >30/min
- Altered mental status
- Hemodynamic instability

Medication Interaction Check

> Check for interactions: warfarin, aspirin, and ibuprofen

Healthcare AI: CRITICAL DRUG INTERACTION DETECTED

Interaction Severity: HIGH RISK

Warfarin + Aspirin + Ibuprofen represents a triple antiplatelet/anticoagulant combination with significant bleeding risk.

Specific Interactions:
1. Warfarin + Aspirin: Increased bleeding risk (moderate-high)
2. Warfarin + Ibuprofen: Increased bleeding risk, possible INR elevation (high)
3. Aspirin + Ibuprofen: Reduced cardioprotective effect of aspirin (moderate)

Clinical Recommendations:
- Avoid concurrent use if possible
- If combination necessary, close monitoring required:
  * Weekly INR monitoring initially
  * Monitor for signs of bleeding
  * Consider GI prophylaxis (PPI)
- Alternative: Consider acetaminophen instead of ibuprofen for pain
- Consult with prescribing physician before making changes

Bleeding Risk Assessment: HIGH (approximately 15-20% annual major bleeding risk)

SOAP Note Generation

> Generate SOAP note for patient with hypertension follow-up

Healthcare AI:

SOAP NOTE - HYPERTENSION FOLLOW-UP

SUBJECTIVE:
Patient is a [age] year old [gender] presenting for routine hypertension follow-up. Reports good medication compliance with current regimen. Denies chest pain, shortness of breath, headaches, or visual changes. No orthostatic symptoms. Home blood pressure readings averaging 128/82 mmHg. Denies any new symptoms or concerns.

OBJECTIVE:
Vital Signs:
- BP: [insert value] mmHg (sitting, right arm)
- HR: [insert value] bpm, regular
- Weight: [insert value] kg (stable compared to last visit)

Physical Examination:
- General: Well-appearing, no acute distress
- Cardiovascular: Regular rate and rhythm, no murmurs
- Respiratory: Clear to auscultation bilaterally
- Extremities: No edema

ASSESSMENT:
1. Essential Hypertension - Well controlled on current therapy
2. [Any additional diagnoses]

Current Medications:
- [List current antihypertensive medications]

PLAN:
1. Continue current antihypertensive regimen
2. Reinforce lifestyle modifications (diet, exercise, weight management)
3. Laboratory: Basic metabolic panel, lipid panel in 6 months
4. Follow-up in 3-6 months or sooner if symptoms develop
5. Patient education provided regarding warning signs
6. Encouraged home blood pressure monitoring

Patient understands and agrees with plan.
