Impact of an educational program on antibiotic use in a tertiary care hospital in a developing country.
A multi-cross-sectional study was conducted in a 2000-bed tertiary care university hospital in Bangkok, Thailand, from September 1993 to May 1994 to assess the effectiveness of an educational program on the use of antibiotics. Data on the study covered antibiotic usage both in-patients and out-patients. Data were collected for a 24-hour period every 2 weeks for 7 days for each 3-month period. The target population were residents, general practitioners, and sixth-year medical students. The educational program provided information derived from the data of inappropriate use of antibiotics during the pre-intervention period and guidelines on the use of antibiotics which were agreed to by a consensus among the faculty in all clinical departments. The study revealed: (1) the prevalence of antibiotic use and the cost of antibiotics during post-intervention period was significantly decreased by 20%; (2) the use of antibiotic prophylaxis for obstetrics patients and patients undergoing cataract surgery decreased significantly; (3) there was a shift from second or third generation cephalosporins to cefazolin for surgical prophylaxis; (4) the duration of perioperative antibiotic prophylaxis was reduced to under 2 days; (5) there was a shift from netilmicin or amikacin to gentamicin for the treatment of community acquired infection; and (6) the mortality, median length of hospital stay, and nosocomial infection rate among the patients who received antibiotics during the post-intervention period were not significantly different from those during the pre-intervention period. These results suggest that this educational program comprising information feedback and antibiotic usage guidelines was effective in improving antibiotic use at this tertiary care university hospital in Thailand.
