ABSTRACT
Abstract@#The diagnosis of bacteremia relies on the isolation and identification of the bacteria from blood cultures, whether they are community-acquired or nosocomial in origin. However, studies have shown that, in the Philippines alone, physicians have been found to underutilize these laboratory examinations. @*Objectives@#The goal of this study was to determine the influence of positive blood cultures and sensitivity test results on the antibiotic choices of pediatrics residents at the University of the Philippines – Philippine General Hospital (UP-PGH). @*Methods@#A chart review of patients with positive blood cultures, who were 18 years old and below, and admitted initially at the UP-PGH Pediatric Emergency Room (UP-PGH PER) from August 1, 2004 to July 31, 2005 was performed. Excluded were patients who died before the release of the blood culture reports or discharged per request or against medical advice, post-operative patients, patients with presumed polymicrobial sepsis, and patients with contaminated blood cultures.

Results:

One hundred twenty two (122) patients with positive blood cultures were included 87 or 71.3% of the isolates were community-acquired, the most common pathogens of which were gram-positive bacteria, Staphylococcus epidermidis (18.3%), followed by gram-negative Salmonella (11.5%). Among the patients diagnosed with bacteremia at the UP-PGH PER, Staph. epidermidis was also the most common pathogen; with 34% of all isolates acquired nosocomially. Other significant isolates included Pseudomonas putida, Pseudomonas aeruginosa, and Klebsiella sp. Prior to the release of the blood culture and sensitivity results, 45 of the 122 patients were already discharged. Therapy at the time of discharge was of questionable efficacy, accounting to 73.3%. Of the 77 patients discharged after the release of blood culture and sensitivity (CS) results, only 21(27%) of the antibiotic therapies were modified, and 56 (73%) were not modified at all. It is imperative to know, however, that 50% of the antibiotic therapies were modified a day after the corresponding blood culture and sensitivity (CS) results came out for patients who presented with nosocomial infection. @*Conclusion@#In general, blood culture and sensitivity test results have a limited effect on the antibiotic choices of pediatric residents at the UP-PGH (University of the Philippines – Philippine General Hospital).
