PNED (Progetto Nazionale Emorragia Digestiva) Score Calculator

상부위장관 출혈 환자 (정맥류 출혈 제외)의 사망률 예측을 위한 점수 체계

Advanced age: 80세 미만 (0점) 80세 이상 (2점)

Time to admission: ≥ 8시간 (0점) ＜ 8시간 (1점)

Low hemoglobin levels at presentation: ≥ 7.0 g/dl (0점) ＜ 7.0 g/dl (2점)

Presence of severe comorbidity:

Recurrent bleeding: No (0점) Yes (Any) (3점)

Failure of endoscopic therapy: No (0점) Yes (Any) (4점)

Poor health status (ASA class): ASA class 1-2 (0점) ASA class 3 (1점) ASA class 4 (3점)
*ASA: American Society of Anesthesiology
ASA class 1: Normal healthy patient
ASA class 2: Patient with mild systemic disease
ASA class 3: Patient with severe systemic disease
ASA class 4: Patient with severe systemic disease that is a constant threat to life
ASA class 5: Moribund patient who is not expected to survive without the operation
ASA class 6: Declared brain-dead patient whose organs are being removed for donor purposes
*참고: PNED 점수 체계에서는 ASA class 5-6을 사용하지 않음. (해당 환자들이 이미 중증도가 극히 높아 예후 예측이 의미가 없거나, 상부위장관 출혈로 입원하는 경우가 드물기 때문)

0~4점: Low risk
5~8점: Medium risk (30-day mortality: 약 10%)
9점 이상: High risk (30-day mortality: 약 32%)
*최대 점수: 23점
