Objective: To examine the influence of nausea and vomiting of pregnancy (NVP) on pregnancy outcomes.

Methods: Outcomes were compared for primigravidas with a current singleton gestation enrolled at <20 weeks' gestation in a maternity risk screening and education program (n = 81 486). Patient-reported maternal characteristics and pregnancy outcomes were compared for women with and without NVP and within the NVP group for those with and without poor weight gain.

Pregnancy outcomes following bariatric surgery.

Objective: To compare pregnancy outcomes postbariatric surgery for women who remain obese at conception to those who were not obese.

Methods: From a database of women who received outpatient perinatal services, we identified women with a history of bariatric surgery who are currently pregnant with a singleton gestation. Available maternal characteristics and pregnancy outcomes were compared between women whose prepregnancy body mass index (PPBMI) remained in the obese range (≥30 kg/m(2)) and those with a PPBMI of <30 kg/m(2) using Fisher exact test, independent Student's t test, and Mann-Whitney U test statistics.

Methods: A retrospective analysis of data collected from patients with a history of preterm birth (PTB) and current singleton gestation enrolled between 16.0 and 20.

The reliability of patient-reported pregnancy outcome data.

Pregnancy and neonatal outcome information is frequently used in disease management to evaluate the cost-effectiveness of prenatal interventions and for other research and reporting activities. The purpose of this study was to determine if a telephone interview process is a reliable methodology for collecting pregnancy outcomes. High-risk patients from a large maternal-fetal medicine practice who received outpatient preterm labor management services from January 1996 to June 2001 were identified.

The risk for preterm labor in women receiving 17 alpha-hydroxyprogesterone caproate prophylaxis for preterm birth prevention.

We sought to identify maternal or clinical characteristics of women likely to develop preterm labor (PTL) at <34 weeks' gestation while receiving 17 alpha-hydroxyprogesterone caproate (17P) prophylaxis. Current singleton gestations with prior preterm delivery enrolled for outpatient 17P administration at <27 weeks' gestation were identified ( N = 1177). Maternal and clinical characteristics were compared between women hospitalized and diagnosed with PTL at <34 weeks' gestation (PTL group, N = 270) and those without PTL (No PTL group, N = 660).

Uterine activity in women receiving 17 alpha-hydroxyprogesterone caproate for the prevention of preterm birth: an observational study.

We evaluated uterine contraction frequency in women receiving 17 alpha-hydroxyprogesterone caproate (17-OHP-C) for the prevention of preterm delivery. Women with singleton pregnancies and receiving weekly 17-OHP-C and outpatient tococardiography were identified from a database. The mean and maximum contraction frequencies per hour were compared from 3 days before to 3 days after 17-OHP-C dosing.

Preterm birth prevention by 17 alpha-hydroxyprogesterone caproate vs. daily nursing surveillance.

Objective: To compare the incidence of spontaneous recurrent preterm delivery (SPTD) between women receiving 17 alpha-hydroxyprogesterone caproate (17P) and women receiving daily perinatal nursing surveillance (dPNS) with home uterine activity monitoring.

Study Design: Women enrolled for dPNS or weekly nursing visits with 17P injection were eligible. Included were singletons with previous SPTD, without preterm labor (PTL), cerclage or vaginal bleeding and < 27 weeks at enrollment.

The impact of maternal obesity on the incidence of adverse pregnancy outcomes in high-risk term pregnancies.

We investigated the impact of maternal obesity on pregnancy outcomes. Women with normal or obese body mass index (BMI) who delivered singleton infants at term were identified from a perinatal database. Rates of pregnancy complications and neonatal outcomes were compared between women with normal prepregnancy BMI (20 to 24.

We compared neonatal outcomes from singleton pregnancies in women hospitalized with preterm labor (PTL) at 32 0/7 to 34 6/7 weeks managed with and without acute tocolysis. Women enrolled for outpatient surveillance who were hospitalized and diagnosed with PTL between 32 0/7; to 34 6/7 weeks' gestation without conditions necessitating interventional delivery during hospitalization were identified ( N = 2921). Patients with contraindications to pregnancy prolongation were excluded ( N = 168).

The impact of maternal body mass on the effectiveness of 17 alpha-hydroxyprogesterone caproate.

Objective: To examine the impact of maternal prepregnancy body mass index (BMI) on rates of recurrent preterm delivery (PTD) in women receiving 17alpha-hydroxyprogesterone caproate (17P) prophylaxis.

Study Design: The study population was identified from a large perinatal database containing prospectively collected information from women at high risk for PTD. We included patients with a current singleton pregnancy and a history of PTD who received weekly nursing visits and 17P 250 mg intramuscular injections beginning at 16.

Antenatal factors predicting subsequent need for insulin treatment in women with gestational diabetes.

Objective: To identify characteristics indicative of subsequent requirement of insulin in patients with gestational diabetes (GDM).

Methods: Identified from a database were patients with GDM not receiving insulin or oral hypoglycemic agents at enrollment for outpatient education and surveillance. Maternal characteristics were compared between patients achieving glycemic control with diet and those requiring insulin.

Management of recurrent preterm labor in twin gestations with nifedipine tocolysis.

We examined outcomes of twin pregnancies complicated by recurrent preterm labor receiving nifedipine tocolysis. In a retrospective study design, twin pregnancies receiving outpatient preterm labor surveillance services and oral nifedipine tocolysis following a diagnosis of preterm labor were identified from a database ( N = 1421). Eligible for inclusion were patients subsequently rehospitalized with recurrent preterm labor symptoms ( N = 862).

Application of disease management principles to pregnancy and the postpartum period.

Pregnancy and newborn care rank among the top health care expenditures for health plans and employers. Traditionally treated as episodic conditions, maternity and newborn clinical management is most often reactive in nature, event driven, and not perceived as a continuum. Existing models of pure disease management are not suited for addressing this continuum because the condition of pregnancy is not a disease, is not chronic, and is self-limited.

Antepartum uterine contraction patterns in twin pregnancies with and without preterm labor and delivering before or after 36 weeks.

Objective: The purpose of this study was to identify differences in antepartum uterine contraction frequency (UCF) in twin pregnancies with and without preterm labor (PTL).

Study Design: Twin gestations enrolled for outpatient surveillance with twice daily electronic uterine activity monitoring and telephonic nursing assessment, without interventional delivery were identified. Mean UCF for each gestational week was compared between women without PTL or preterm delivery (PTD) < 36 weeks (controls) and those with a PTL diagnosis delivering at < 36 weeks (PTL/PTD group), and those with PTL with delivery > or = 36 weeks (PTL/GAD > or = 36 group).

Clinical characteristics of women prescribed 17 alpha-hydroxyprogesterone caproate in the community setting.

Objective: The objective of the study was to describe clinical characteristics and pregnancy outcomes of women in a community setting prescribed 17 alpha-hydroxyprogesterone caproate (17P) prophylaxis for prevention of preterm delivery (PTD).

Study Design: A retrospective review was conducted of data collected from patients enrolled for weekly outpatient 17P administration and nursing assessment between April 2004 and January 1, 2006 (n = 1979). Pregnancy history, referral indication, labor/delivery onset (spontaneous or indicated), and gestational duration were identified.
