Safely send more low-risk pneumonia patients home

PSI Class I–II patients have <1% mortality and can be treated at home — yet 30–40% are unnecessarily admitted because the score takes too long to calculate manually. DoctorScribe auto-computes PSI in real-time and prints the discharge instructions in the patient's language.

Clinical Disclaimer: PSI is validated in adults with confirmed CAP. It under-weights young, otherwise healthy patients with severe disease — clinical judgement should override a low PSI if SpO₂ < 92%, multilobar consolidation, or unreliable home situation. Not validated in pregnancy, HIV, or post-transplant. Always verify against your local prescribing reference and apply clinical judgment.

The PSI score, in one click — not 5 minutes of arithmetic

DoctorScribe pulls age, sex, comorbidities, vitals, ABG/SpO₂, electrolytes, and the X-ray report straight from the chart, calculates PSI + CURB-65 + SMART-COP simultaneously, and writes the right guideline antibiotic onto the prescription.
