IBMP-10 Score of Mirsaeidi et al for Predicting Mortality for Patients with Ventilator-Associated Pneumonia (VAP)

Purpose: To evaluate a patient with ventilator-associated pneumonia (VAP) using the predictive score of Mirsaeidi et al.

Description

Mirsaeidi et al developed a score for predicting mortality for patients with ventilator-associated pneumonia (VAP). This can help to identify patients who may benefit from more aggressive management. The authors are from the IMPACT-HAP Investigators (Improving Medicine through Pathway Assessment of Critical Therapy of Hospital-Acquired Pneumonia).


Patient selection: presence of ventilator-associated pneumonia

 

Parameters (5):

(I) for immunodeficiency

(B) for blood pressure

(M) for multilobular pulmonary infiltrate

(P) for platelet count

(10) for duration of hospitalization > 10 days before onset of VAP

= SUM(points for all 5 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 5

• The higher the score the greater the risk of mortality.
