Low colony counts of asymptomatic group B streptococcus bacteriuria: a survey of practice patterns.
The purpose of this study was to survey expert opinion on the management of low colony counts (< 100,000 colony forming units/mL) of asymptomatic group B streptococcus (GBS) bacteriuria discovered in the first trimester. A survey was sent to the 241 senior obstetricians affiliated with each of the Obstetrics and Gynecology training programs in the United States on July 10, 2002. Surveys received by the deadline (September 1, 2002) were included in the dataset. Eighty-five completed surveys were returned for a response rate of 35%. Seventy-seven percent reported treating low colony counts of asymptomatic GBS bacteriuria in the first trimester at the time of diagnosis, whereas 23% stated they did not treat prior to labor (margin of error 7.5% with 95% confidence). Nine percent stated that their institution had a written protocol for the treatment of low colony counts of asymptomatic GBS bacteriuria. Two physicians indicated that they screened for asymptomatic GBS bacteriuria at 28 weeks. Currently, no generally accepted protocol for the management of low colony counts of asymptomatic GBS bacteriuria exists. This survey indicates that most of the responding senior obstetricians at United States training programs treat low colony counts of asymptomatic GBS bacteriuria in the first trimester.
