PSI Calculator — Pneumonia Severity Index
Quickly assess the severity of community-acquired pneumonia (CAP) with our free PSI Calculator. This tool helps you calculate PSI (Pneumonia Severity Index) based on clinical factors, guiding decisions for outpatient treatment, hospitalization, or ICU care.
How to Use the PSI Calculator?
- Enter patient’s age, vital signs, lab values, and comorbidities.
- Click “Calculate PSI” to get the score and risk class.
- Use the score to guide hospitalization decisions.
PSI Score Interpretation
| PSI Class | Risk Level | Recommended Action |
|---|---|---|
| I – II | Low Risk | Outpatient care |
| III | Moderate | Brief hospitalization or outpatient |
| IV – V | High Risk | Hospitalization, consider ICU |
What Is the PSI Pneumonia Severity Index Calculator?
- Explain that it’s a clinical tool validated in studies.
- Mention that it’s used specifically for community-acquired pneumonia (CAP).
- Different from CURB-65 but both help in risk stratification.
CURB-65 vs PSI Calculator: What’s the Difference?
- CURB-65 is simpler, fewer inputs.
- PSI often preferred when labs are available.
You can calculate PSI easily by entering clinical details into our PSI Calculator.
The PSI score is a tool used to assess the risk of mortality in patients with community-acquired pneumonia (CAP). It helps guide clinical decisions regarding the need for hospitalization or ICU care based on a patient’s severity risk classification.
PSI is calculated by assigning points based on a patient’s age, comorbidities, vital signs, lab results, and mental status, then summing the total to determine pneumonia severity risk.
The PSI score categorizes patients into five risk classes (I to V), where lower classes suggest outpatient care and higher classes recommend hospitalization or intensive care.
CURB-65 is a simpler pneumonia severity tool based on confusion, urea, respiratory rate, blood pressure, and age ≥65; PSI is more detailed but offers greater accuracy by including comorbidities and lab data.
The PSI score measures the risk of mortality in community-acquired pneumonia patients, helping guide decisions between outpatient treatment and hospital admission.
The PSI score helps clinicians stratify pneumonia patients based on severity, ensuring that they receive the appropriate treatment in the correct setting (e.g., outpatient, inpatient, or ICU). This stratification improves patient outcomes by guiding timely and appropriate interventions.
