Abstract

PurposeClinicians lack a validated tool for risk stratification for need for mechanical ventilation (MV) in acute exacerbations of chronic obstructive pulmonary disease (AECOPD). We sought to compare 2 risk scores, BAP-65 and CURB-65, at predicting a need for MV in AECOPDs.Materials and MethodsWe analyzed 34 478 AECOPD admissions to 195 US hospitals (2007). We compared the rates of MV at admission and at any point during hospitalization based on the respective BAP-65 and CURB-65 scores. We compared the accuracy of the 2 scores via the area under the receiver operating characteristic curves.ResultsThe overall MV rate at admission was 7.9%, and the rate of MV any time equaled 9.3%. Use of MV increased with escalating BAP-65 and CURB-65 scores. The area under the receiver operating characteristic curve for BAP-65 was higher than that for CURB-65 for both early MV, 0.81 (95% confidence interval [CI], 0.80-0.82) vs 0.76 (95% CI, 0.75-0.77), P < .0001, and MV any time, 0.78 (95% CI, 0.77-0.79) vs 0.74 (95% CI, 0.73-0.75), P < .0001.ConclusionsBAP-65 identifies patients with AECOPD at high risk for need of MV more accurately than does CURB-65. BAP-65 may represent a useful tool for initial MV risk stratification in AECOPD.
