✅ Criteria for Safe Hospital Discharge

Patients should meet ALL criteria before discharge is considered safe and appropriate.

Clinical Stability Criteria

📊 Vital Signs Normalization

Temperature: ≤ 37.5°C (99.5°F) for ≥24 hours without antipyretics
Heart Rate: 60-100 bpm (or baseline rate if known)
Respiratory Rate: 12-20 breaths/minute
Blood Pressure: Systolic ≥90 mmHg, Diastolic ≥60 mmHg (no vasopressors)
SpO₂: ≥92% on room air (or baseline for COPD patients)
Alert & Oriented: Normal mental status (no confusion/delirium)

🫁 Respiratory Function

No Respiratory Distress: No tachypnea, stridor, or use of accessory muscles
Adequate Oxygenation: pO₂ ≥60 mmHg on room air (or stable baseline)
No Hypercapnia: pCO₂ normal range or chronic baseline
Effective Cough: Able to expectorate secretions
No Supplemental O₂ Requirement: Or minimal requirement (<2-3 L/min)

💊 Oral Intake & Medications

Adequate Oral Intake: Able to eat and drink without difficulty
No Dysphagia: No aspiration risk, normal swallowing
Tolerating Oral Medications: No IV medications required
Nausea/Vomiting Controlled: Not requiring IV antiemetics
Bowel Function Intact: Regular bowel movements

Infectious Disease Criteria

🧬 Laboratory & Microbiological

WBC Count: ≤11,000/μL (normalized or trending down)
CRP/Procalcitonin: Normalized or significantly decreased
Blood Cultures: Negative (if initially positive)
Sputum Culture: No new pathogenic organisms identified
No Fever: Afebrile for ≥24-48 hours
Antibiotic Course: Completed appropriate duration (7-10 days for CAP)

⛔ Criteria for Continued Hospitalization

Patients meeting ANY of these criteria should NOT be discharged.

Clinical Instability - RED FLAGS

🚨 Vital Sign Abnormalities

Persistent Fever: Temperature >38°C despite antibiotics (>48-72 hours)
Tachycardia: HR >120 bpm persistently
Tachypnea: RR >24 breaths/minute or acute worsening
Hypotension: SBP <90 mmHg requiring vasopressor support
Hypoxemia: SpO₂ <90% on room air, requiring supplemental O₂
Altered Mental Status: Confusion, delirium, decreased LOC

🫁 Respiratory Compromise

Respiratory Distress: Use of accessory muscles, stridor, grunting
Hypoxemia: pO₂ <60 mmHg despite supplemental oxygen
Hypercapnia: pCO₂ >50 mmHg with respiratory acidosis
Need for Mechanical Ventilation: Current intubation or impending need

Infectious Disease Criteria - RED FLAGS

🧬 Microbiological/Laboratory Concerns

Positive Blood Cultures: Bacteremia present, requires investigation
Persistent WBC Elevation: WBC >15,000/μL with left shift
Rising CRP/Procalcitonin: Increasing inflammatory markers despite therapy
Resistant Organisms: MRSA, MDR gram-negatives, fungal agents
Treatment Failure: No improvement by 48-72 hours on antibiotics

⛔ Continued Stay RED FLAG Checklist

☐

Fever >48-72 hours - Temperature remains >38°C despite antibiotics

☐

Hypoxemia - SpO₂ <90% or pO₂ <60 mmHg

☐

Respiratory Distress - RR >24 or accessory muscle use

☐

Hemodynamic Instability - Hypotension, tachycardia, or shock

☐

Altered Mental Status - New confusion, delirium, decreased LOC

☐

Positive Blood Cultures - Evidence of bacteremia

☐

Resistant Organisms - MRSA, MDR gram-negatives, fungi

📋 Clinical Assessment Tools

CURB-65 Score at Discharge Assessment

CURB-65 Score	Discharge Readiness	Action
0-1 (Low Risk)	Excellent candidate for discharge	Discharge with outpatient follow-up; oral antibiotics
2 (Intermediate)	Safe to discharge if clinically stable	Monitor 24 hours; transition to oral meds
≥3 (High Risk)	Requires continued hospitalization	Do NOT discharge; continue IV antibiotics

PSI (Pneumonia Severity Index) - Risk Stratification

PSI Class	Mortality	Discharge Recommendation
Class I	<0.1%	✅ Safe outpatient management
Class II	0.6%	✅ Consider discharge after observation
Class III	0.9-1.3%	⚠️ Brief hospitalization required
Class IV	6.8-8.2%	❌ Hospitalization required
Class V	27-31%	❌ ICU-level care required

📞 Discharge & Follow-up Care Planning

Follow-up Schedule

Timeframe	Action/Assessment	By Whom
24-48 hours	Telephone check-in; confirm medication compliance	Nurse or PCP
1 week	In-person PCP visit; assess treatment response	Primary Care Physician
4 weeks	Assess symptom resolution; repeat labs if needed	Primary Care Physician
1-3 months	Repeat CXR if immunocompromised or prolonged symptoms	PCP or Pulmonology

⚠️ Warning Signs - Seek Emergency Care If:

Return fever (>38.5°C)
Worsening shortness of breath
Chest pain or hemoptysis
Mental status changes
Severe fatigue or syncope
