Which one is superior in predicting 30 and 90 days mortality after COPD exacerbation: DECAF, CURB-65, PSI, BAP-65, PLR, NLR.

OBJECTIVES The major scores associated with the mortality after COPD exacerbations were; DECAF, CURB-65, PSI and BAP-65 scores. We aimed to compare these scores in predicting 30- and 90-day mortality in patients hospitalized with exacerbation of COPD. METHODS The data of 141 patients who were hospitalized with the diagnosis of COPD exacerbation between January 2018 and March 2019 and accepted to participate in the study were prospectively recorded. RESULTS Age, mean modified-medical-research-council (mMRC) dyspnea score, pleural effusion, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), presence of atrial fibrillation (AF), PaCO2 pressure values ​​were found to be significantly higher at both 30 and 90-days deceased group, while hemoglobin, albumin and pH values ​​were significantly lower (all p<0.05). DECAF, CURB-65, PSI and BAP-65 scores were significantly higher for both 30 and 90-days mortality (all p<0.05). DECAF, CURB-65, PSI, BAP-65 scores, PLR, NLR predicted to 30 day and 90 day mortality. But, CURB-65 found (OR 2.968 and 2.284, respectively) superior to others in predicting 30 and 90-days mortality. CONCLUSIONS CURB-65 score is a significant, simple and feasible score for predicting 30 and 90 days mortality in COPD exacerbation and may be routinely used in all patients hospitalized with COPD exacerbation.
