[A retrospective analysis of community-acquired pneumonia between 2000 and 2002 in a community hospital].
We previously reported a hospital-based retrospective study on community-acquired pneumonia (CAP) at Tagami Hospital, which was a community hospital, between 1994 and 1997. This study was designed to clarify the etiology of CAP diagnosed between 2000 and 2002. We analyzed a total of 124 cases of CAP in our hospital during the study period, and compared the results with the previous data. Identification of the causative organisms of CAP was based on gram staining, the morphology of the colonies, quantitative culture of the sputum, and the serological tests. During the study period, we determined the causative organisms in 42 cases (33.8%). Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were the major causative organisms. The severity of the cases was classified into three groups according to the guideline for CAP, which was edited by the Japanese Respiratory Society. The survival rates in the moderate and severe groups were significantly (p < 0.001) higher than that of the mild group, as analyzed by the Kaplan-Meier method, as follows: 70% (moderate) vs 100% (mild); and 40% (severe) vs 100% (mild). In a total of 7 patients who died, we found the following risk factors: elderly male patients, bedridden status with cerebral infarction, and micro-aspiration, including recurrent pneumonia at short intervals of less than 17 days. Our study indicated that the JRS-edited guideline for CAP is a very useful tool for analyzing cases with CAP in Japan.
