Pneumonia is the one of the most common infectious diseases treated in the ambulatory and hospital setting. It is the 4th leading cause of morbidity and the 3rd leading cause of mortality among Filipinos based on the 1994 Philippine Health Statistics from the Department of Health. In Jose R. Reyes Memorial Medical Center (JRRMMC), pneumonia is the leading cause of morbidity (rate-19.7%) and mortality (case fatality rate-20.5%) among patients admitted at medical ward (JRRMMC - Department of Medicine Records 1999).
STUDY DESIGN: Retrospective Study
STUDY SETTING: JRRMMC Medical Ward
STUDY SUBJECTS: Patients admitted and discharged with principal or secondary diagnosis of community acquired-pneumonia from January 1, 2000 to December 31, 2000 were eligible for the study.
A total of 153 potential pneumonia cases were abstracted. Using the above mentioned exclusion criteria, 27 patients (17.6%) were excluded. Reasons for exclusion were the following: died or discharged on the date of admission (21 patients), had chemotherapy or immunosuppression treatment within 2 months (5 patients) and experienced acute care hospitalization within 10 days (1 patient). Case confirmation using the ICD-9 CM code rendered 41 patients (26.8%) unqualified. A total of 85 patients (55.6%) were left with confirmed diagnosis of pneumonia and no exclusion.
