Prevention of recurrent preterm birth: role of the neonatal follow-up program

Can We Predict Preterm Delivery Based on the Previous Pregnancy?

(1) Background: Preterm deliveries (PTD, <37 gestational weeks) which occur in 5–18% of deliveries across the world, are associated with immediate and long-term offspring morbidity, as well as high costs to health systems. Our aim was to identify risk factors during the first pregnancy ending at term for PTD in the subsequent pregnancy. (2) Methods: A retrospective population- based nested case−control study was conducted, including all women with two first singleton consecutive deliveries. Women with PTD in the first pregnancy were excluded. Characteristics and complications of the first pregnancy were compared among cases, defined as women with PTD in their second pregnancy, and the controls, defined as women delivering at term in their second pregnancy. A multivariable logistic regression model was used to study the association between pregnancy complications (in the first pregnancy) and PTD (in the subsequent pregnancy), while adjusting for maternal age and the interpregnancy interval. (3) Results: A total of 39,780 women were included in the study, 5.2% (n = 2088) had PTD in their second pregnancy. Women with PTD, as compared to controls (i.e., delivered at term in second pregnancy), were more likely to have the following complications in their first pregnancy: perinatal mortality (0.4% vs. 1.0%), small for gestational age (12.4% vs. 8.1%), and preeclampsia (7.6% vs. 5.7%). In the multivariable model, after adjusting for maternal age, interpregnancy interval and co-morbidities, having any one of these first pregnancy complications was independently associated with an increased risk for PTD (adjusted OR = 1.44; 95%CI 1.28–1.62), and the risk was greater if two or more complications were diagnosed (adjusted OR = 2.09; 95%CI 1.47–3.00). These complications were also risk factors for early PTD (<34 gestational weeks), PTD with a systematic infectious disease in the background, and possibly with spontaneous PTD. (4) Conclusions: First pregnancy complications are associated with an increased risk for PTD in the subsequent pregnancy. First pregnancy, although ending at term, may serve as a window of opportunity to identify women at risk for future PTD.

Contraceptive Method Choices in Women With and Without Opioid Use Who Have Infants in the Neonatal Intensive Care Unit and Nursery

Objective: The aim of this study was to examine whether a history of opioid use predicts tier 1 contraceptive use or plan to use in women with infants in the neonatal intensive care unit (NICU) and nursery.

Materials and Methods: We conducted a self-administered, anonymous survey in women with infants in three local NICUs and two postpartum units from November 2018 to May 2019. Women were recruited while visiting their infants in the NICU or in their postpartum rooms. Our survey included adapted questions from the Centers for Disease Control and Prevention (CDC) Pregnancy Risk Assessment Monitoring System (PRAMS) questionnaire, the National Institute of Drug Abuse (NIDA) Modified ASSIST Screening Tool, and ones written by our team. The questions asked about contraceptive use and opioid use. We compared the responses of women with and without a history of opioid use. We conducted a multivariable regression analysis and applied the backward elimination method to identify whether opioid use was a predictor of tier 1 contraceptive use or plan to use.

Results: A total of 122 women completed the survey. Fifty-three women (43.4%) reported opioid use in the month before pregnancy and/or during pregnancy, while 69 (56.6%) women reported no opioid use and comprised the control group. Multivariable regression analysis showed that opioid use was not associated with the use or planned use of tier 1 contraceptives (adjusted odds ratio [aOR] 1.47; confidence interval [95% CI] 0.54–4.01). Older maternal age predicted tier 1 choice (aOR 1.12; 95% CI 1.04–1.21), while African American women were less likely to use or plan to use tier 1 contraceptives compared with white women (aOR 0.21; 95% CI 0.08–0.56).

Conclusion: A history of opioid use was not independently associated with women using or planning to use tier 1 methods, while age and race were predictors.

Meeting the Needs of Postpartum Women With and Without a Recent Preterm Birth: Perceptions of Maternal Family Planning in Pediatrics

OBJECTIVES

Women face distinct barriers to meeting their reproductive health needs postpartum, especially women who deliver preterm. Pediatric encounters present unique opportunities to address women's family planning, particularly within 18 months of a prior pregnancy, when pregnancy has an elevated risk of an adverse outcome, such as preterm birth. To ensure maternal family planning initiatives are designed in a patient-centered manner, we explored perspectives on addressing reproductive health in a pediatric setting among women with and without a recent preterm delivery.

METHODS

We conducted semi-structured, qualitative interviews with 41 women (66% delivered preterm). Women who delivered at any gestational age were interviewed at a pediatric primary care clinic. We also interviewed women whose infants were either in a level II intensive care nursery or attending a high-risk infant follow-up clinic, all of whom had delivered preterm. Data were analyzed using team-based coding and theme analysis.

RESULTS

While women's preferred timing and setting for addressing peripartum contraception varied, they largely considered pediatric settings to be an acceptable place to discuss family planning. A few women felt family planning fell outside of the pediatric scope or distracted from the child focus. Women discussed various barriers to accessing family planning care postpartum, including circumstances unique to women who delivered preterm.

CONCLUSIONS FOR PRACTICE

Family planning interventions in pediatric settings were overall an acceptable approach to reducing barriers to care among our sample of women who predominantly delivered preterm. These exploratory findings justify further investigation to assess their generalizability and to develop maternal family planning interventions for pediatric settings.

Prevention of Prematurity: Advances and Opportunities

Preterm birth (PTB) rate varies widely and has significant racial and ethnic disparities. Although causal mechanisms are ill understood, socioenvironment, phenotype, and genotype provide insight into pathways for preventing PTB. Data suggest varied response to current medical interventions is explicable Approved by underlying pharmacogenomics. Currently, prevention focuses on minimizing iatrogenic PTB and risk reduction especially in those with prior PTB using proven medical and public health strategies. In the future, preventive approaches will be based on better understanding of sociodemography, nutrition, lifestyles, and underlying individual genetic and epigenetic variation. Statistical approaches and "big-data" models are critical in future study.

Pregnancy after periviable birth: making the case for innovative delivery of interpregnancy care

Objective: Women who have had a spontaneous periviable delivery are at high risk for recurrent preterm delivery. The objective of our study was to determine interpregnancy interval (IPI) after periviable birth as well as percentage of women taking 17 alpha hydroxyprogesteronecaproate (17OHP-C) after periviable birth. We then examined the association between adherence with a postpartum visit after a periviable birth and IPI as well as receipt of 17OHP-C. Materials and methods: We included all women with a periviable delivery (20-26-week gestation) due to spontaneous preterm birth at Magee Women's Hospital between 2009 and 2014, who had their subsequent delivery at our institution during or before May of 2016. Information on maternal, fetal, and neonatal outcomes was obtained from the Magee Obstetrical Medical and Infant (MOMI) database as well as chart abstraction. We calculated IPI, proportion of women who received 17OHP-C in their next pregnancy, and attendance rates with a postpartum visit. The relationship between attendance with a postpartum visit and IPI, and receipt of 17OHP-C was examined with a logistic regression. Results: During the study period, 361 women had a spontaneous periviable birth. A total of 60 women had a subsequent delivery at Magee Women's Hospital. Only 33/60 (52.5%) presented for a postpartum visit after their periviable delivery. The median IPI for the cohort was 12.5 months (interquartile range: 6.4, 17.5 months) and 21.0% (n = 13) had an IPI less than 6 months. Adherence with the postpartum visit was not associated with an IPI less than 6 months. A total of 18.33% (11 women) did not receive 17OHP-C in their subsequent pregnancy. Women who attended a postpartum visit were much more likely to receive 17OHP-C (p = .001). Conclusions: Many women with a history of a periviable birth do not optimize strategies to reduce their risk of recurrent preterm birth. While attendance with a postpartum visit was associated with greater receipt of 17OHP-C in the subsequent pregnancy, given the overall poor rate of attendance with the postpartum visit in this cohort, novel strategies to counsel women about interpregnancy health are needed.

Addressing Unmet Maternal Health Needs at a Pediatric Specialty Infant Care Clinic

OBJECTIVE

The objective of this intervention was to evaluate the feasibility of screening mothers of medically fragile infants in the domains of 1) depression, 2) tobacco exposure, and 3) family planning at a post-neonatal intensive care unit (NICU) developmental pediatric visit. Additionally, we sought to estimate the percentage who met criteria for further evaluation in the three domains assessed.

METHODS

A cross-sectional questionnaire was administered to 100 caregivers of medically fragile infants at a specialty, post-NICU clinic visit. Participants' responses in three domains were evaluated and appropriate referrals were provided. Analysis was then restricted to the 87 biological mothers who completed the screening. Study staff contacted the mothers 2 months later to determine whether services had been accessed and to assess overall satisfaction with the screening within the pediatric visit. Qualitative interviews were conducted with pediatric clinic staff.

RESULTS

Screening questionnaires were completed by 87 biological mothers. Twenty-two mothers (25%) met referral criteria. Pediatric clinic staff and providers were comfortable administering the screening instrument, and there was minimal disruption to clinic flow.

CONCLUSIONS

Mothers of medically fragile infants are likely to have unmet health care needs that can be identified at a specialty pediatric clinic visit. A screening and referral intervention can be implemented with minimal interruption in pediatric clinic flow and is acceptable to mothers and pediatric providers.

Postpartum contraception needs of women with preterm infants in the neonatal intensive care unit

OBJECTIVES

To evaluate postpartum contraception experiences of mothers with premature infants in the neonatal intensive care unit (NICU), their knowledge of risk factors for preterm delivery and their interest in a family planning clinic located near the NICU.

STUDY DESIGN

This is a cross-sectional survey of English or Spanish-speaking women 18 or older whose premature neonate had been in the NICU for 5 days or more in a current stable condition.

RESULTS

A total of 95 women were interviewed at a median of 2.7 weeks postpartum (range 0.6-12.9). Approximately 75% of women were currently using or planning to use contraception, with 33% using less effective methods. Half of women reported they would obtain contraception at a family planning clinic near the NICU. Only 32% identified a short interpregnancy interval as a risk factor for preterm delivery.

CONCLUSION

Lack of knowledge of short interpregnancy interval as a risk factor for a future preterm delivery highlights the need to address postpartum contraception education and provision in this high-risk population.
