Prophylactic antibiotics and evaluation scheme following febrile urinary tract infection in children: a nationwide Israeli survey.

ABSTRACT

BACKGROUND: Although febrile urinary tract infections are very common in young children, the need for antimicrobial prophylaxis and evaluation following a first event is controversial. OBJECTIVES: To assess the approach of leading pediatric specialists throughout israel to antimicrobial prophylaxis. METHODS: A questionnaire regarding the approach to antibiotic prophylaxis and diagnostic evaluation following a first event of febrile UTI, according to age and underlying renal abnormality, was sent to all 58 directors of departments of pediatrics, units of pediatric infectious diseases and pediatric nephrology in Israel. RESULTS: Fifty-six directors (96%) responded. Most prescribed prophylactic antibiotics after UTI. Heads of infectious disease departments prescribed less prophylaxis following UTI at the age of 18 months than heads of pediatrics or heads of pediatric nephrology units (34% vs. 72-75%, P = 0.018), but more often in cases of severe vesico-ureteral reflux without UTI. Cephalosporins were used prophylactically more often by directors of pediatrics compared to heads of pediatric nephrology units (71% vs. 38%, P = 0.048); the latter used non-beta-lactam prophylaxis (61% vs. 23%, P = 0.013) more often. Most pediatricians used renal sonography for evaluation; renal scan was used more commonly by pediatric nephrologists. CONCLUSIONS: The administration of prophylactic antibiotics after UTI is still common practice among pediatric opinion leaders, although the specific approach differs by subspecialty. According to the latest evidence-based data, educational efforts are needed to formulate and implement judicious guidelines.
