GALEANO UGARTE, Deisy Florencia. Predictive value of severity scores in community acquired pneumonia. Rev. virtual Soc. Parag. Med. Int. [online]. 2016, vol.3, n.2, pp.85-94. ISSN 2312-3893.

Introduction: CURB-65 and PSI scores have been designed to stage patients with acute community acquired pneumonia (CAP) in order to determine severity and make therapeutic decisions. Objectives: To determine the stage at discharge and the mean length of stay of patients with CAP staged using CURB-65 and PSI scores and admitted to the Hospital Nacional (Itauguá, Paraguay) in 2014 and 2015. Methodology: Design of retrospective cohorts where 60 adult patients with CAP were staged according to the severity by using CURB-65 and PSI scores. Results: The highest points in the CURB-65 score (3-5 points) were associated with higher mortality (53.3% vs. 6.6%) and shorter hospital stay (11 ± 8 days vs. 14 ± 8 days). The highest points in the PSI score (>91 points) were associated with higher mortality (37.5% vs. 0%) and longer hospital stay (13 ± 8 days vs. 12 ± 7 days). Age higher than 65 years old and the presence of co-morbidities were risk factors for CAP. Conclusions: CURB-65 and PSI scores predict mortality and length of hospital stay in patients with CAP.
