Usage Examples

Basic Medical Query

$ ollama run Jayasimma/healthsoft

> What are the common causes of chest pain?

HealthSoft: Common causes of chest pain include:

Cardiac Causes:
1. Angina (stable or unstable)
2. Myocardial infarction (heart attack)
3. Pericarditis
4. Myocarditis
5. Aortic dissection

Non-Cardiac Causes:
1. Gastroesophageal reflux disease (GERD)
2. Costochondritis (chest wall pain)
3. Pulmonary embolism
4. Pneumonia or pleurisy
5. Pneumothorax
6. Anxiety or panic attacks
7. Musculoskeletal strain

RED FLAGS requiring immediate evaluation:
- Severe, crushing chest pain
- Pain radiating to arm, jaw, or back
- Shortness of breath
- Diaphoresis (sweating)
- Nausea/vomiting
- Loss of consciousness

Any chest pain should be evaluated by a healthcare provider to rule out serious conditions.

Drug Interaction Check

> Check interaction between metformin and contrast dye

HealthSoft: IMPORTANT DRUG-PROCEDURE INTERACTION

Interaction: Metformin + Iodinated Contrast Media

Severity: MODERATE TO HIGH

Risk: Lactic Acidosis (rare but serious)

Mechanism:
- Contrast media may temporarily impair kidney function
- Reduced kidney function can lead to metformin accumulation
- Risk of lactic acidosis increases

Recommendations:
1. Assess kidney function (eGFR) before procedure
2. If eGFR >30 mL/min: Generally safe, but hold metformin for 48 hours after procedure
3. If eGFR <30 mL/min: Consider alternative imaging or hold metformin 48h before and after
4. Ensure adequate hydration
5. Recheck kidney function before restarting metformin

Patient Monitoring:
- Watch for symptoms of lactic acidosis: weakness, muscle pain, breathing difficulty
- Resume metformin only after confirming normal kidney function

Always consult with ordering physician and follow institutional protocols.

Symptom Assessment

> Patient with fever 102F, productive cough, and fatigue for 4 days. Assessment?

HealthSoft: Clinical Assessment:

Chief Complaint: Fever, productive cough, fatigue x 4 days

Differential Diagnosis (most likely first):
1. Acute Bronchitis - Most common, especially if viral prodrome
2. Community-Acquired Pneumonia - Consider with high fever and productive cough
3. COVID-19 - Must consider in current context
4. Influenza - Especially during flu season
5. Acute exacerbation of chronic lung disease (if history present)

Recommended Evaluation:
- Vital signs: Temperature, SpO2, respiratory rate, heart rate, blood pressure
- Lung examination: Listen for crackles, wheezing, decreased breath sounds
- Sputum color and consistency
- Associated symptoms: Shortness of breath, chest pain, confusion

Suggested Workup:
- Pulse oximetry (SpO2)
- Chest X-ray (if pneumonia suspected or SpO2 <92%)
- COVID-19 test
- Consider CBC if bacterial infection suspected

Management Considerations:
- Hydration
- Antipyretics for comfort
- Cough suppressants if needed
- Antibiotics only if bacterial pneumonia confirmed
- Outpatient vs inpatient based on severity scores (CURB-65, PSI)

Seek immediate care if:
- SpO2 <90-92%
- Respiratory distress
- Altered mental status
- Hemodynamic instability

Medical Abbreviation Explanation

> What does COPD exacerbation management include?

HealthSoft: COPD Exacerbation Management:

COPD = Chronic Obstructive Pulmonary Disease

Acute Exacerbation Treatment:

1. Bronchodilators (First-line):
   - Short-acting beta-agonists (SABA): Albuterol nebulizer or inhaler
   - Short-acting anticholinergics (SAMA): Ipratropium
   - Combination therapy often used

2. Corticosteroids:
   - Prednisone 40mg PO daily x 5 days OR
   - Prednisolone 30-40mg daily x 5-7 days
   - Reduces recovery time and treatment failure

3. Antibiotics (if indicated):
   Indications: Increased sputum purulence + volume/dyspnea
   - First-line: Amoxicillin-clavulanate, doxycycline, or respiratory fluoroquinolone
   - Duration: 5-7 days typically

4. Oxygen Therapy:
   - Target SpO2: 88-92%
   - Avoid over-oxygenation (risk of CO2 retention)

5. Supportive Care:
   - Adequate hydration
   - Chest physiotherapy if needed
   - Nutrition support

6. Hospital Admission Criteria:
   - Severe dyspnea
   - Altered mental status
   - SpO2 <90% despite oxygen
   - Respiratory acidosis (pH <7.35)
   - Hemodynamic instability
   - Inability to manage at home

7. Prevention:
   - Smoking cessation counseling
   - Vaccination (influenza, pneumococcal)
   - Pulmonary rehabilitation
   - Long-term maintenance therapy optimization

Follow-up in 2-4 weeks to reassess and adjust maintenance therapy.
