  1. Fulltext. The Boston AIDS Survival Score (BASS) : A multidimensional AIDS severity instrument.

    Article - En anglais



    This study developed a new acquired immunodeficiency syndrome (AIDS) severity system by including diagnostic, physiological, functional, and socio-demographic factors predictive of survival.


    Three-hundred five persons with AIDS in Boston were interviewed ; their medical records were reviewed and vital status ascertained.


    Overall median (±SD) survival for the cohort from the first interview until death was 560 ± 14.4 days.

    The best model for predicting survival, the Boston AIDS Survival Score, included the Justice score (stage 2 relative hazard [RH]=1.25,95% confidence interval [Cl]=0.80,1.96 ; stage 3 RH=1.76,95% Cl=1.15,2.70), a newly developed opportunistic disease score (Boston Opportunistic Disease Survival Score ; stage 2 RH=1.35,95% CI=0.90,2.02 ; stage 3 RH=2.10,95% Cl=1.38,3.18), and measures of activities of daily living (any intermediate limitations, RH=1.84,95% Cl=1.05,3.21 ; any basic limitations, RH=2.60,95% Cl=1.44,4.69).

    This model had substantially greater predictive power (R2=17, C statistic=68) than the Justice score alone (R2=09, C statistic=61).


    Incorporating data on clinically important events and functional status into a physiologically based system can improve the prediction of survival with AIDS.
