Prognostic Score of Hasbun et al for an Adult with Left-Sided Native Valve Endocarditis

Purpose: To evaluate the prognosis for an adult with endocarditis involving a left-sided native heart valve using the score of Hasbun et al.

Description

Hasbun et al developed a prognostic score for adults with endocarditis involving a left-sided, native heart valve. This can help identify patients who require more aggressive therapy and closer monitoring. The authors are from Tulane and Yale Universities.


Parameters:

(1) mental status

(2) Charlson comorbidity scale

(3) congestive heart failure

(4) culture isolate

(5) therapy

Interpretation:

• minimum score: 0

• maximum score: 23

• The higher the score, the worse the prognosis.
