We investigated if clinicians were altering their care of group B streptococcus (GBS)-positive women in labor to achieve 4 hours of intrapartum antibiotic prophylaxis based on their interpretation of the 2002 Centers for Disease Control (CDC) guidelines on prevention of perinatal GBS disease. We surveyed all clinicians with privileges on the labor floor at our institution about their interpretation and clinical application of the 2002 CDC guidelines. Seventy of 96 eligible clinicians (72.9%) completed our survey. In our survey, only 22.9% of clinicians reported not altering their management of labor in GBS-positive pregnancies that achieved less than 4 hours of prophylaxis. These alterations included "laboring down" or delaying pushing; turning off or decrease an oxytocin infusion; or delaying or avoiding artificial rupture of membranes. Clinicians are altering their management of labor to attempt to achieve 4 hours of intrapartum prophylaxis. The 2002 CDC guidelines do not specifically recommend prolonging labor and are being interpreted differently in the clinical setting than the authors may have intended. The effects and consequences of this interpretation are unknown.

    ABSTRACT: Cesarean delivery rates have increased remarkably worldwide. The indications for this increase are not fully understood and there may be regional, ethnic or health system differences in quoted indications which may explain, at least in part, the observed changes. In 2008 China was cited as having one of the highest rates of cesarean delivery in the world, but there was no accurate information about the indications for the high rate. This study sought to provide some information about the high cesarean section rate in China. Data on all births in a university teaching hospital in northern China serving a general obstetric population, excluding premature births, were collected from the hospital database from January 2009 to September 2012. All indications on the mode of delivery were analyzed for live births. There were 5267 births and the cesarean delivery rate was 41.4% in the study period. There was no significant trend in the cesarean delivery rate from 2009 to 2012. Fetal indications contributed most to the rate. More than 50% of all cesarean deliveries were due to nuchal cord, previous cesarean delivery, fetal distress and malpresentation. The rate of cesarean delivery on maternal request was 9.07%. Smaller contributions to the indications for cesarean delivery came from cephalopelvic disproportion, preeclampsia, prolonged labor, uterine rupture and other obstetric conditions. The data show increased fetal or maternal risk assessments are the main indications for cesarean delivery rather than cesarean delivery on maternal request in China.
