Adverse Pregnancy Conditions Among Privately Insured Women With and Without Congenital Heart Defects.

ABSTRACT: Background In women with congenital heart defects (CHD), changes in blood volume, heart rate, respiration, and edema during pregnancy may lead to increased risk of adverse outcomes and conditions. The American Heart Association recommends providers of pregnant women with CHD assess cardiac health and discuss risks and benefits of cardiac-related medications. We described receipt of American Heart Association-recommended cardiac evaluations, filled potentially teratogenic or fetotoxic (Food and Drug Administration pregnancy category D/X) cardiac-related prescriptions, and adverse conditions among pregnant women with CHD compared with those without CHD. Methods and Results Using 2007 to 2014 US healthcare claims data, we ascertained a retrospective cohort of women with and without CHD aged 15 to 44 years with private insurance covering prescriptions during pregnancy. CHD was defined as ≥1 inpatient code or ≥2 outpatient CHD diagnosis codes >30 days apart documented outside of pregnancy and categorized as severe or nonsevere. Log-linear regression, accounting for multiple pregnancies per woman, generated adjusted prevalence ratios (aPRs) for associations between the presence/severity of CHD and stillbirth, preterm birth, and adverse conditions from the last menstrual period to 90 days postpartum. We identified 2056 women with CHD (2334 pregnancies) and 1 374 982 women without (1 524 077 pregnancies). During the last menstrual period to 90 days postpartum, 56% of women with CHD had comprehensive echocardiograms and, during pregnancy, 4% filled potentially teratogenic or fetotoxic cardiac-related prescriptions. Women with CHD, compared with those without, experienced more adverse conditions overall (aPR, 1.9 [95% CI, 1.7-2.1]) and, specifically, obstetric (aPR, 1.3 [95% CI, 1.2-1.4]) and cardiac conditions (aPR, 10.2 [95% CI, 9.1-11.4]), stillbirth (aPR, 1.6 [95% CI, 1.1-2.4]), and preterm delivery (aPR, 1.6 [95% CI, 1.4-1.8]). More women with severe CHD, compared with nonsevere, experienced adverse conditions overall (aPR, 1.5 [95% CI, 1.2-1.9]). Conclusions Women with CHD have elevated prevalence of adverse cardiac and obstetric conditions during pregnancy; 4 in 100 used potentially teratogenic or fetotoxic medications, and only half received an American Heart Association-recommended comprehensive echocardiogram.

Project description:BACKGROUND:Infants younger than 6?months are at increased risk of complications and mortality from pertussis infection. In October 2012, the Advisory Committee on Immunization Practices revised its recommendation to include a Tdap dose during each pregnancy, ideally between 27 and 36?weeks gestation. OBJECTIVE:Assess trends in Tdap vaccination coverage among privately insured pregnant women from 2009 to 2016 including timing of Tdap vaccination (before, during, or after pregnancy), trimester of vaccination for women vaccinated during pregnancy, and missed vaccination opportunities for unvaccinated women. Identify factors associated with vaccination during the optimal period of 27-36?weeks gestation. STUDY DESIGN:Retrospective analysis of privately insured women 15-49?years who delivered live births during 2009-2016 conducted using 2009-2016 MarketScan data. Tdap vaccination coverage and the timing of Tdap vaccine administration were assessed for women continuously enrolled from 6?months before pregnancy to 1?month after delivery. Multivariable logistic regression was performed to identify factors independently associated with receipt of Tdap vaccine at 27-36?weeks gestation. RESULTS:Tdap vaccination coverage during pregnancy increased from 0.4% in 2009 to 6.2% in 2012 and to 53.2% in 2016. The proportion of vaccinated women receiving Tdap at 27-36?weeks gestation increased from <10% in 2009 to nearly 90% in 2016, with most vaccination occurring at 27-32?weeks gestation. Women of older age, residing in a metropolitan statistical area, residing outside the South, and having a capitated health insurance plan were more likely to receive Tdap at 27-36?weeks gestation than their counterparts. Among women not vaccinated during pregnancy, 77.7% had a pregnancy-related medical claim between 27 and 36?weeks gestation. CONCLUSION:Tdap vaccination coverage during pregnancy increased significantly from 2009 to 2016, with the greatest increase occurring after the revised Advisory Committee on Immunization Practices recommendation. Most women who did not receive Tdap vaccine had a missed vaccination opportunity during pregnancy, indicating potential for much higher vaccination coverage and consequent infant protection against pertussis.

Project description:ImportanceThe extent to which assisted reproductive technology is associated with increased risk of congenital heart defects independent of its known association with twinning remains uncertain.ObjectiveTo assess the extent to which assisted pregnancy is associated with increased risk of congenital heart defects independent of its known association with twinning.Design, setting, and participantsThis retrospective cohort study linked records of congenital heart defect diagnoses with assisted reproductive technology cycles in 507 390 singleton or twin pregnancies (10 149 assisted pregnancies and 497 241 nonassisted pregnancies), including singleton and twin early pregnancy losses, stillbirths, and live births (follow-up to 1 year of age) in Ontario, Canada, between April 1, 2012, and October 31, 2015. Statistical analysis was performed from January 1, 2017, to September 9, 2019.ExposuresAssisted reproductive technology and its 2 subtypes: intracytoplasmic sperm injection and in vitro fertilization without intracytoplasmic sperm injection.Main outcomes and measuresThe main outcome was congenital heart defects (prevalence and relative risk measured as odds ratios [ORs]). Mediation analysis was performed to assess the extent to which the association between assisted reproductive technology and congenital heart defects was mediated by twinning.ResultsOf 507 390 mother-infant pairs with singleton or twin pregnancies evaluated, the prevalence of congenital heart defects in assisted pregnancies (223 [2.2%]) was higher than that in nonassisted pregnancies (6057 [1.2%]; crude OR, 1.82; 95% CI, 1.59-2.09). The strength of the association between assisted pregnancy and congenital heart defects decreased after adjusting for several risk factors simultaneously (adjusted OR, 1.70; 95% CI, 1.48-1.95). Further mediation analysis indicated that most of the association between assisted pregnancy and congenital heart defects was mediated by twinning (adjusted OR, 1.68; 95% CI, 1.44-1.92), and the natural direct association of assisted pregnancy with congenital heart defects among singleton pregnancies was 1.09 (95% CI, 0.93-1.25). Mediation of twinning accounted for 87.3% of the association.Conclusions and relevanceOur study results suggest that the association between assisted reproductive technology and congenital heart defects may be mediated by twinning.

Project description:OBJECTIVE:To analyze utilization of, and payments for, pelvic organ prolapse procedures after the 2011 U.S. Food and Drug Administration (FDA) communication regarding transvaginal mesh. METHODS:This is a retrospective cohort study examining private claims from three insurance providers for inpatient and outpatient prolapse procedures from 2010 to 2013 in the Health Care Cost Institute. Primary outcomes were the change in utilization of prolapse procedures, with and without mesh, before and after the July 2011 FDA communication. Secondary outcomes were the changes in payments and reimbursements for these procedures. Utilization rates and payments were compared using generalized linear models and interrupted time-series analysis. RESULTS:Utilization of prolapse procedures decreased from 12.3 to 9.7 per 10,000 woman-years (P=.027) with a decrease of 30.7% (3.9 in 2010 to 2.7 in 2013, P=.05) in number of mesh procedures and 16.6% (8.4 in 2010 to 7.0 in 2013, P=.011) for nonmesh procedures. Quarterly utilization of mesh procedures was increasing before the FDA communication and then significantly declined after its release (slope=0.024 vs -0.025, P=.002). Nonmesh procedures, however, were already slightly decreasing before July 2011 and continued to decline at a more rapid pace after that time, although not significantly (slope=-0.004 vs -0.022, P=.47). Inpatient utilization decreased 52.2% (P=.002), whereas outpatient utilization increased 18.5% (P=.132). Payments for individual inpatient procedures, with and without mesh, increased by 12.0% ($8,315 in 2010 to $9,315 in 2013, P=.001) and 15.6% ($7,826 in 2010 to $9,048 in 2013, P=.005), respectively, whereas those for outpatient procedures increased by 41% ($4,961 in 2010 to $6,981 in 2013, P=.006) and 30% ($3,955 in 2010 to $5,149 in 2013, P=.004), respectively. CONCLUSION:Use of prolapse surgery declined during the study period. After the 2011 FDA communication regarding transvaginal mesh, there was a significant decrease in the utilization of procedures with mesh but not for those without mesh. A shift toward outpatient surgeries was observed, and payments for both individual inpatient and outpatient cases increased.
