title: [Comparison of five guidelines of community-acquired pneumonia].
abstract: The aim of this retrospective study was to elucidate the characteristics of five guidelines of community-acquired pneumonia: ATS (1993), ATS (2001), IDSA (1998), IDSA (2000) and the guidelines of the Japan Respiratory Society (2000). One hundred community-acquired pneumonia patients admitted to the International Medical Center of Japan were investigated in accordance with each set of guidelines based on the physical, laboratory, and chest radiography findings on the first day of treatment. According to the ATS (1993) guidelines, 33% of the cases were classified as "severe" pneumonia. On the other hand, according to the ATS (2001) guidelines, only 8% of the cases were classified as "severe" pneumonia. According to the IDSA guidelines, 35% of the patients were classified as "outpatients". Fluoroquinolone appears to be a very important antibiotic drug in the new guidelines of both ATS and IDSA. The scoring system of IDSA suggested a correlation between the patient's score and the pathogenic bacteria. According to the guidelines of the Japan Respiratory Society, 42% of the cases were classified as "severe" pneumonia. There are evident differences between these guidelines, and clinicians need to have a full understanding of their respective characteristics.
