Receipt of American Heart Association-Recommended Preconception Health Care Among Privately Insured Women With Congenital Heart Defects, 2007-2013.

Background Our objective was to estimate receipt of preconception health care among women with congenital heart defects (CHD), according to 2017 American Heart Association recommendations, as a baseline for evaluating recommendation implementation. Methods and Results Using 2007 to 2013 IBM MarketScan Commercial Databases, we identified women with CHD diagnosis codes ages 15 to 44 years who became pregnant and were enrolled in health insurance for ≥11 months in the year before estimated conception. We assessed documentation of complete blood count, electrolytes, thyroid-stimulating hormone, liver function, ECG, comprehensive echocardiogram, and exercise stress test, using procedural codes, and outpatient prescription claims for US Food and Drug Administration category D and X cardiac-related medications. Differences were examined according to CHD severity, age, region of residence, year of conception, and documented encounters at obstetric and cardiology practices. We found 2524 pregnancies among 2003 women with CHD (14.4% severe CHD). In the 98.3% of women with a healthcare encounter in the year before conception, <1% received all and 22.6% received no American Heart Association-recommended tests or assessments (range: 54.4% for complete blood count to 3.1% for exercise stress test). Women with the highest prevalence of receipt of recommended care were 35 to 44 years old, pregnant in 2012 to 2013, or had a documented obstetric or cardiology encounter in the year before conception (P<0.05 for all). In 9.0% of pregnancies, ≥1 prescriptions for US Food and Drug Administration category D or X cardiac-related medications were filled in the year before conception. Conclusions A low percentage of women with CHD received American Heart Association-recommended preconception health care in the year before conception.

Intrapartum predictors of uterine rupture.

This case-controlled study reviewed 26 cases of uterine rupture at an academic medical center. Controls were selected in a 2:1 design by reviewing the immediate successful vaginal birth after cesarean delivery (VBAC) before and after each case of uterine rupture. At less than 2 hours before delivery or acute uterine rupture, mild and severe variable decelerations, persistent abdominal pain, and hyperstimulation were more common in cases of uterine rupture as compared to controls and had statistically significant positive likelihood ratios (LR). Mild and severe variable fetal heart rate decelerations, especially in the presence of persistent abdominal pain, may predict uterine rupture in patients attempting VBAC.

Diabetic nephropathy in pregnancy: suboptimal hypertensive control associated with preterm delivery.

BACKGROUND: Nephropathy complicates 5% to 10% of pregnancies in women with diabetes and is associated with adverse outcomes. Given the importance of blood pressure (BP) control in reducing cardiovascular and renal complications outside of pregnancy, we hypothesized that poorly controlled hypertension in early pregnancy among women with diabetic nephropathy would be associated with adverse outcomes. METHODS: To examine the impact of hypertensive control in early pregnancy on perinatal outcomes, we performed a retrospective cohort study of pregnancies complicated by diabetic nephropathy with "Above Target" mean arterial pressure (> or = 100 mm Hg; N = 21) and "Below Target" mean arterial pressure (< 100 mm Hg; N = 22), which approximates the American Diabetes Association and the Seventh Report of the Joint National Committee recommended target of 130/80 mm Hg, measured at < 20 weeks' gestation. RESULTS: There were no differences in maternal age (mean +/- SEM: 27.2 +/- 1.2 v 29.5 +/- 1.0 years), duration of diabetes (median, range: 17.5, 13 to 24 v 16, 1 to 25 years), or glucose control (glycosylated hemoglobin [HbA1c] 8.0% +/- 0.3% v 8.1% +/- 0.4%) between the Above and Below Target groups. The Above Target group had more proteinuria (4.69 +/- 1.08 v 1.65 +/- 0.43 g/24 h; P = .007) and higher serum creatinine levels (1.23 +/- 0.17 v 0.85 +/- 0.06 mg/dL; P = .02). The Above Target group was more likely to deliver at < 32 weeks' gestation (38.1% v 4.6%; P = .007). The increased risk of preterm delivery remained significant after adjusting for duration of diabetes and glucose control. CONCLUSIONS: Suboptimal control of hypertension in early pregnancy in women with diabetic nephropathy is associated with a significant risk of preterm delivery. Improved preconceptional control of hypertension may reduce adverse perinatal outcomes in women with diabetic nephropathy.
