Abstract
Background: PSI and CURB65 are two of the most widely used scales for predicting mortality related to CAP. However, CURB65 accuracy to predict mortality has not been validated in elderly population.
Aim: To analyze the predictive mortality value of CURB65 scale versus PSI score in patients with CAP older than 65 years old.
Methods: A 12 months prospective multicenter and longitudinal study was performed in several hospitals of a Spanish mediterranean area (Comunidad Valenciana). We included patients over 65 with CAP diagnosis. We analyzed mortality related factors (comorbidities, clinical, radiological and laboratory findings, complications) and mortality risk related to PSI or CURB65 scores. Statistical analysis included Chi Square with significance p<0.05.
Results: 750 patients were included, with mean age of 76.7±7.5 years, 63.9% of them were men. 5.1% died. In our cohort, mortality rate attending PSI score or CURB65 was consistent as reported series (Table 1). However, CURB65 classified as low risk a higher percentage of patients considered by PSI score as moderate-severe risk p<0.001 (Table 2).
Conclusions: Although mortality rate in our cohort is closed to reported data, CURB65 in elderly patients with CAP underestimate the severity of CAP, compared to PSI scores.
