ROLE OF PNEUMONIA SEVERITY INDEX AND CURB-65 SCORE IN PATIENTS WITH ACUTE EXACERBATION OF COPD WITH REFERENCE TO THEIR DURATION OF HOSPITAL STAY

Aim and Objective: To investigate the role of Pneumonia Severity Index and CURB-65 score in patients with acute exacerbation of COPD with reference to Duration of hospital stay. Methods:In our study a total of 100 patients of COPD with acute exacerbation were included in the study from the tertiary care Centre, Kolkata for a period of 12 months from December 2015 to November 2016. Results: The relationship between Respiratory rate, Arterial pH, Urea and BUN levels, Blood glucose, Hematocrit level, pO2 as well as PSI and CURB-65 score in reference with duration of hospital was found to be significant. Our study revealed that PSI and CURB-65 score have good predictive capacity for in hospital deaths as well as duration of hospital stay. Conclusion: PSI and CURB -65 can predict the duration of hospital stay, with a good prognostic capacity. The role of PSI and CURB-65 in defining duration of hospital stay needs to be assessed by further studies on larger samples using Indian data for reference value. The present study is a stimulus to future research on role of PSI, CURB-65 as well as comorbidities in defining the outcome of acute exacerbations in COPD, one of the most dreaded respiratory diseases.
