The Association Between Hospital Obstetrical Volume And Maternal Postpartum Complications, Kathy Kyser, Xin Lu, Donna Santillan, Mark Santillan, Stephen Hunter, Alison Cahill, Peter Cram

Stephen K. Hunter

OBJECTIVE: The purpose of this study was to examine the relationship between delivery volume and maternal complications. STUDY DESIGN: We used administrative data to identify women who had been admitted for childbirth in 2006. Hospitals were stratified into deciles that were based on delivery volume. We compared composite complication rates across deciles. RESULTS: We evaluated 1,683,754 childbirths in 1045 hospitals. Decile 1 and 2 hospitals had significantly higher rates of composite complications than decile 10 (11.8% and 10.1% vs 8.5%, respectively; P < .0001). Decile 9 and 10 hospitals had modestly higher composite complications as compared with decile 6 (8.8% and …

Perinatal Management Of Women With Immune Thrombocytopenic Purpura: Survey Of United States Perinatologists, D. Peleg, Stephen Hunter

Stephen K. Hunter

OBJECTIVE: The aim of the study was to determine how perinatologists in the United States manage the care of women with immune thrombocytopenic purpura with respect to mode of delivery. Study Design: US members of the Society of Perinatal Obstetricians were surveyed with a 4-question questionnaire. Two mailings were sent. Questions 1 and 2 asked for a response regarding the perinatal management of delivery for women with chronic immune thrombocytopenic purpura and new-onset disease. The options were cordocentesis or fetal scalp blood sampling and cesarean delivery if the platelet count was <50,000 cells/microL, cesarean delivery if the maternal platelet count …

RESULTS: We evaluated 1,683,754 childbirths in 1045 hospitals. Decile 1 and 2 hospitals had significantly higher rates of composite complications than decile 10 (11.8% and 10.1% vs 8.5%, respectively; P < .0001). Decile 9 and 10 hospitals had modestly higher composite complications as compared with decile 6 (8.8% and 8.5% vs 7.6%, respectively; P < .0001). Sixty percent of decile 1 and 2 hospitals were located within 25 miles of the nearest greater volume hospital.

CONCLUSION: Women who deliver at very low-volume hospitals have higher complication rates, as do women who deliver at …

Group B Streptococci Causing Neonatal Bloodstream Infection: Antimicrobial Susceptibility And Serotyping Results From Sentry Centers In The Western Hemisphere, J. Andrews, D. Diekema, Stephen Hunter, P. Rhomberg, M. Pfaller, R. Jones, G. Doern

Stephen K. Hunter

OBJECTIVE: Group B streptococcal infection is a common cause of neonatal sepsis. Surveillance of antimicrobial susceptibility and serotype frequencies of invasive group B streptococci is important to ensure the effectiveness of therapeutic regimens and to guide vaccine development. STUDY DESIGN: Prospective surveillance of neonatal bloodstream infection was performed at all Western Hemisphere sites participating in the SENTRY Program. From January 1997 through December 1999, a total of 122 isolates of bloodstream infections with group B streptococci were collected and sent to the University of Iowa for antimicrobial susceptibility testing and serotyping. RESULTS: No isolates were resistant to penicillin. More than …
