Abstract

Background: Pneumonia severity index (PSI) has an important role in making decision in treatments and prognosing. However, it does not include the factor of corticosteroid-related immunodeficiency, which is popular in Vietnam, in its citeria. Objectives: Describe the clinical charateristics and value of PSI in prognosing community-acquired pneumonia patients and in corticosteroid-related immunodeficient patients. Materials and methods: Descriptive retrospective study of 558 community-acquired pneumonia patients in General Medicine Department, Can Tho University of Medicine and Pharmacy Hospital from 2016 to 2021. Results: General group – corticosteroid-related immunodeficient subgroup: the mean age was 72,4 ± 14,3 and 69,3 ± 11,8 years, male ratio was 50,4% and 44,2%. Hospital length of stay median was 7 days for both groups. Mean PSI was 82,5 ± 26,4 and 95,6 ± 22,0 (p < 0,001). 30-day mortality rate was 6,5% và 12,1% (p < 0,001). 30-day mortality prognosing ability of PSI was average, AUC = 0,696 (general group) and weak, AUC = 0,578 (subgroup). Conclusions and suggestions: PSI helps in prognosing hospital length of stay and 30-day mortality rate in both general group and corticosteroid-related immunodeficient subgroup, more research nees to be made on the power of prognosing based on AUC.
