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.
