Association of prenatal substance use with prenatal and postpartum care: Evidence from the Pregnancy Risk Assessment Monitoring System, 2016-2019

The objective of this study was to build on existing qualitative research to estimate the association of prenatal substance use with prenatal and postpartum care. We used data from the 2016-2019 Pregnancy Risk Assessment Monitoring System for 9 states. We conducted adjusted linear regression to compare month of gestation of first prenatal visit and adjusted logistic regression to compare receipt of adequate prenatal care and a postpartum healthcare visit among women who reported prenatal use of any opioids, prescription opioids, marijuana, and illicit drugs to those who did not report use of each substance. Women who reported prenatal use of any opioids (Risk Difference(RD) = 0.16; 95% Confidence Interval (CI) = 0.04, 0.28), prescription opioids (RD = 0.16; 95% CI = 0.04, 0.28), marijuana (RD = 0.25; 95% CI = 0.10, 0.41) and illicit drugs (RD = 0.52; 95% CI = 0.09, 0.95) initiated prenatal care later than those who did not report use of each substance. Women who reported prenatal use of any opioid (Odds Ratio (OR) = 0.82; 95% CI = 0.68, 1.00), prescription opioids (OR = 0.84; 95% CI = 0.69, 1.02), marijuana (OR = 0.59; 95% CI = 0.48, 0.73) and illicit drugs (OR = 0.29; 95% CI = 0.20, 0.42) were less likely to receive adequate prenatal care. Women who reported prenatal use of any opioid (OR = 0.82, 95% CI = 0.65, 1.04), prescription opioids (OR = 0.83; 95% CI = 0.66, 1.05), marijuana (OR = 0.65; 95% CI = 0.51, 0.82) and illicit drugs (OR = 0.47; 95% CI = 0.30, 0.72) had a lower likelihood of a postpartum visit than those who did not report use of each substance. Results indicate potential intervention points for pregnant women who use substances.

Bacteriuria in Pregnant Adolescents and Behavioral Risk Factors: A Cross-Sectional Study at a Brazilian Teaching Hospital

INTRODUCTION

Bacteriuria during pregnancy is a frequent and important cause of morbidity and complications. Data on its occurrence in pregnant adolescents are still scarce.

METHODS

A cross-sectional study was conducted at a tertiary teaching hospital in São Paulo, Brazil. All adolescents (≤18 years) who came for prenatal care between January 2010 and January 2016 were included. Sociodemographic characteristics, medical history, obstetric history, and the results of laboratory tests were selected. A urine sample was aseptically collected from each patient to undergo microscopic and culture analysis.

RESULTS

A total of 388 pregnant adolescents averaging 15.30 ± 1.24 years of age were included. The frequency of bacteriuria in this group was 17.01% (66/388). The lack of sports practice (OR = 8.65; 95% CI, 1.09-68.39), the fact that pregnancy was desired (OR = 2.17; 95% CI, 1.08-4.34), and the use of hormonal methods of contraception (OR = 2.46; 95% CI, 1.04-5.84) turned out to be independent risk factors for bacteriuria. Protective factors were identified as late coitarche (OR = 0.75; 95% CI, 0.57-0.98) and a urine culture analysis at a later gestational age (OR = 0.94; 95% CI, 0.90-0.98). The most often isolated pathogens were Escherichia coli (49%) and Streptococcus agalactiae (18%).

CONCLUSION

Bacteriuria among pregnant adolescents is a relatively common condition. The infection risk of the urinary tract was increased by physical inactivity and seemingly by the influence of behavioral and sexual factors. Such results can help to identify patients at risk, favoring the early diagnosis of urinary tract infections and optimizing prenatal care.

Participant attrition and perinatal outcomes in prenatal vitamin D-supplemented gestational diabetes mellitus patients in Asia: A meta-analysis

BACKGROUND

The role of vitamin D supplementation in gestational diabetes mellitus (GDM) patients is unclear.

AIM

To determine the burden and risk of post-randomization GDM patient attrition from vitamin D-supplemented arms of randomized controlled trials (RCTs). The auxiliary aim was to compare the effects of nutritional supplements on their fasting blood glucose (FPG) levels and perinatal outcomes.

METHODS

RCTs were searched in the PubMed, Embase, and Scopus databases. Random-effect prevalence and pairwise meta-analysis were performed for the primary objective. The auxiliary aim was to compare the effects of nutritional supplements on their fasting blood glucose (FPG) levels and perinatal outcomes. Fixed-effect network meta-analyses were undertaken for the secondary goals. All analyses were performed using Stata software, and statistical significance was determined at P < 0.05.

RESULTS

Thirteen RCTs from Iran and China were reviewed. The participant attrition burden in vitamin D recipients was 6% [95% confidence interval (CI): 0.03, 0.10], and its risk did not vary from non-recipients. Vitamin D and calcium co-supplementation reduced the cesarean section incidence in GDM patients [risk ratio (RR): 0.37; 95%CI: 0.18, 0.74]. The hyperbilirubinemia or hospitalization risk in their newborns decreased with vitamin D supplementation (RR: 0.47; 95%CI: 0.27, 0.83) and co-supplementation with calcium (RR: 0.35; 95%CI: 0.16, 0.77) or omega-3 fatty acids (RR: 0.25; 95%CI: 0.08, 0.77). Vitamin D and probiotics co-supplementation decreased newborn hyperbilirubinemia risk (RR: 0.28; 95%CI: 0.09, 0.91). FPG levels and macrosomia risk did not vary across interventions.

CONCLUSION

In RCTs, vitamin D supplementation or co-supplementation in GDM patients showed a low participant attrition burden and low risk of cesarean section, newborn hyperbilirubinemia, and newborn hospitalization.

Prenatal healthcare after sentencing reform: heterogeneous effects for prenatal healthcare access and equity

Background

High rates of imprisonment in the U.S. have significant health, social, and economic consequences, particularly for marginalized communities. This study examines imprisonment as a contextual driver of receiving prenatal care by evaluating whether early and adequate prenatal care improved after Pennsylvania’s criminal sentencing reform reduced prison admissions.

Methods

We linked individual-level birth certificate microdata on births (n = 999,503) in Pennsylvania (2009–2015), to monthly county-level rates of prison admissions. We apply an interrupted time series approach that contrasts post-policy changes in early and adequate prenatal care across counties where prison admissions were effectively reduced or continued to rise. We then tested whether prenatal care improvements were stronger among Black birthing people and those with lower levels of educational attainment.

Results

In counties where prison admissions declined the most after the policy, early prenatal care increased from 69.0% to 73.2%, and inadequate prenatal care decreased from 18.1% to 15.9%. By comparison, improvements in early prenatal care were smaller in counties where prison admissions increased the most post-policy (73.5 to 76.4%) and there was no change to prenatal care inadequacy (14.4% pre and post). We find this pattern of improvements to be particularly strong among Black birthing people and those with lower levels of educational attainment.

Conclusions

Pennsylvania’s sentencing reforms were associated with small advancements in racial and socioeconomic equity in prenatal care.

Public health perinatal promotion during COVID-19 pandemic: a social media analysis

Background

Canadian public health agencies, both municipal/regional and provincial/territorial, are responsible for promoting population health during pregnancy and the early postnatal period. This study examines how these agencies use web-based and Facebook channels to communicate perinatal health promotion during the emergence of the COVID-19 pandemic.

Methods

Perinatal health promotion content of websites and Facebook posts from a multijurisdictional and geographically diverse sample of government and non-governmental organizations (NGO) were evaluated using thematic content analysis in 2020.

Results

Major Facebook perinatal health promotion themes included breastfeeding, infant care, labor/delivery, parenting support and healthy pregnancy. Facebook COVID-19-themed perinatal health promotion peaked in the second quarter of 2020. Websites emphasized COVID-19 transmission routes, disease severity and need for infection control during pregnancy/infant care, whereas Facebook posts focussed on changes to local health services including visitor restrictions. NGO perinatal health promotion reflected organizations’ individual mandates.

Conclusions

Canadian government use of Facebook to disseminate perinatal health promotion during the COVID-19 pandemic varied in terms of breadth of topics and frequency of posts. There were missed opportunities to nuance transmission/severity risks during pregnancy, thereby proactively countering the spread of misinformation.

High-risk pregnant women's experiences of the receiving prenatal care in COVID-19 pandemic: a qualitative study

Background

Women with high-risk pregnancies are among the most vulnerable groups that require additional precautionary measures against the spread of COVID-19 plus receiving prenatal care. Yet, there is limited information on the status of prenatal care in women with high-risk pregnancies. The purpose of this study was to explore the experiences of women with high-risk pregnancies who were receiving prenatal care during the COVID-19 pandemic.

Methods

The present qualitative study was conducted on mothers with high-risk pregnancies from September 2020 to March 2021. Purposeful sampling continued until achieving data saturation. Ghaem, Ommolbanin, and Imam Reza in Mashhad, Iran served as the research environment. Face-to-face and semi-structured interviews were effective data collection methods. Each interview lasted between 20 to 45 min (on average 30). The total number of participants was 31. Data analysis was carried out simultaneously with data collection using the qualitative content analysis method developed by Granheim and Landman (2004).

Results

Following the reduction and analysis of data from women in high-risk pregnancies, as well as their perceptions and experiences with health services during the COVID-19 pandemic, eight subcategories and three main categories were identified, including 1) “Negative psychology responses,” 2) “Adoption behavior,” and 3) “Adjustment of health services in mutual protection.”

Fear, anxiety, stress, feelings of loneliness, sadness, depression, guilt, doubt and conflict in receiving services were examples of negative psychological responses. The adaptive behaviors’ category reflected the behaviors of women with high-risk pregnancies in the context of the COVID COVID-19 pandemic. The Adjustment of health services in mutual protection indicated that health workers took preventive and protective measures against COVID-19, which, in addition to protecting themselves and their clients against COVID-19, gave women a sense of security.

Conclusion

Receiving prenatal care during the COVID-19 pandemic presents challenges for women with high-risk pregnancies, negatively impacting their psychological state and health-seeking behavior. Supportive and preventive care can ensure that women with high-risk pregnancies receive optimal prenatal care that focuses on COVID-19 prevention. We recommend implementing screening, psychological counseling, and education for women with high-risk pregnancies, as well as ensuring that they have access to women-centered health care services.

The effects of an epidemic on prenatal investments, childhood mortality and health of surviving children

The potential death toll from an epidemic is larger than the number of deaths directly associated with the infection. In this study, we find that prenatal exposure to a cholera epidemic in Peru increased childhood mortality and that surviving children were more likely to be underweight and to suffer from diarrhea. We further find that a significant part of this mortality happened during the first day of life, and that prenatal exposure to cholera decreased prenatal care and institutional deliveries, suggesting that the mortality and possibly other longer-term effects were partially driven by a reduction in prenatal investments.

Virtual Prenatal and Postpartum Care Acceptability Among Maternity Care Providers

Introduction

The Covid-19 pandemic and statewide stay-at-home orders abruptly impacted clinic operations necessitating the incorporation of telehealth. Uptake of telehealth is multifaceted. Clinician acceptance is critical for success. The aim of this study is to understand maternity care providers’ acceptance of and barriers to providing virtual maternity care.

Methods

Providers completed a baseline and 3-month follow up survey incorporating the validated implementation outcome measures, feasibility of intervention measure (FIM), intervention appropriateness measure (IAM), and acceptability of intervention measure (AIM).Statistical analyses evaluated differences between groups in this small convenience sample to understand trends in perceptions and barriers to telehealth. While not intended to be a qualitative study, a code tree was used to evaluate open-ended responses.

Results

Baseline response rate 50.4% (n = 56). Follow-up retention/response-rate 68% (n = 38). Most reported no prior telehealth experience. 94% agreed with the FIM, decreasing to 92% at follow-up. 80% (prenatal) and 84% (postpartum) agreed with the IAM. Agreement with the AIM increased to 83%.Differences in the FIM and AIM found by division (p < 0.01) and years in practice (p < 0.01). Identified barriers included patient lack of essential tools, inadequate clinic support, and patients prefer in person visits. Themes that emerged included barriers, needs, and areas of success.

Discussion

Telehealth was found to be feasible, appropriate, and acceptable across provider types and divisions. Improving patient/provider access to quality equipment is imperative. Future research must address how and when to incorporate telehealth.

Vaginal-perianal or vaginal-perineal compared with vaginal-rectal culture-based screening for Group B Streptococci (GBS) colonization during the third trimester of pregnancy: a systematic review and meta-analysis

Background

Screening for maternal anogenital Group B streptococci (GBS) colonization in pregnancy with initiation of intravenous intrapartum antibiotic prophylaxis as indicated has led to a significant reduction in the incidence of neonatal GBS infection. This study aims to evaluate the agreement between vaginal-perianal or vaginal-perineal culture and the more typically used vaginal-rectal culture for screening for maternal anogenital GBS colonization in the third trimester of pregnancy.

Methods

Eligible English-language studies published until January 2020 were retrieved from Scopus, Web of Science, PubMed, Embase, and ClinicalTrials.gov databases. Studies were compiled that assessed for GBS colonization utilizing vaginal-perianal or vaginal-perineal culture and vaginal-rectal culture during the third trimester of pregnancy. Nonoriginal research articles and studies that did not assess pregnant patients, did not use culture-based screening, or did not compare vaginal-perianal or vaginal-perineal culture with vaginal-rectal culture were excluded. The search identified 559 articles with three prospective cohort studies that met inclusion criteria, including 643 participants. Quality was assessed using the Newcastle–Ottawa Scale, and risk of bias was assessed using the Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool. Patient characteristics and associated pain with specimen collection were abstracted. Meta-analyses of both the raw agreement and the Cohen’s kappa statistic were performed.

Results

Within the three included studies, the range of GBS detection was 17.6–34.0%, consistent with the anticipated prevalence of GBS colonization reported in earlier publications. For both raw agreement and Cohen’s kappa coefficient, the test for heterogeneity was not significant, indicating low heterogeneity among studies. The pooled estimate of the raw agreement was 0.97 (95%CI 0.95–0.98) and of the Cohen's kappa coefficient was 0.91 (95% CI: 0.87–0.95), indicating (according to the Landis and Koch criteria) an “almost perfect” agreement between the compared clinical tests. In the two studies that assessed procedure-related patient discomfort, vaginal-rectal swabbing caused more discomfort.

Conclusion

Use of vaginal-perineal culture for assessment of maternal GBS colonization is comparable to the more typically utilized vaginal-rectal culture and is associated with less discomfort.

Maternal anxiety, depression and vascular function during pregnancy

OBJECTIVE

We aim to clarify whether type and timing of mental health symptoms in early pregnancy distinctly contribute to maternal-fetal vascular function, independent from the psychotropic medications given to treat these conditions.

METHODS

Data from a prospective cohort study (n = 1678) were used to test whether self-reported fears about giving birth and depressive symptoms prior to 16 weeks of gestation were associated with vascular outcomes predictive of hypertensive disorders of pregnancy (HDP) i.e., systolic and diastolic blood pressure (BP); uterine artery pulsatility index (UAPI); umbilical artery resistance index (UmbARI); and urine protein creatinine ratio. Multiple linear regressions models and mediation models were used to test for associations between predictors and outcomes, controlling for previously identified risk factors for vascular dysfunction such as maternal age and history of infertility.

RESULTS

Fears about giving birth in early pregnancy were inversely associated with UmbARI (β = -0.33, p = 0.03, df = 51) mid- to late-pregnancy (≥20 weeks). Depressive symptoms in early pregnancy were also inversely associated with maternal systolic BP (β = -0.13, p = 0.01, df = 387) and diastolic BP (β = -0.10, p = 0.04, df = 387) during the first trimester.

CONCLUSIONS

While fears about giving birth in early pregnancy were associated with lower vascular resistance in the fetal-placental unit, early depressive symptoms were associated with lower maternal vascular tone. At the very least, our results support the notion that early maternal psychological distress is unlikely to account for the development of HDP later during pregnancy and provide preliminary evidence to support distinct roles of pregnancy-related anxiety and depressive symptoms in maternal-fetal vascular function.

Healthcare professionals' experiences and perceptions regarding health care of indigenous pregnant women in Ecuador

BACKGROUND

Pregnancy is an important life experience that requires uniquely tailored approach to health care. The socio-cultural care practices of indigenous pregnant women (IPW) are passed along the maternal line with respect to identity, worldview and nature. The cultural differences between non-indigenous healthcare professionals (HPs) and IPW could present a great challenge in women's health care. This article presents an analysis from a human rights and gender perspective of this potential cultural divide that could affect the health of the IPW in an Andean region of Ecuador with the objective of describing the health challenges of IPWs as rights holders through the experiences and perceptions of HP as guarantors of rights.

METHODS

We conducted 15 in-depth interviews with HPs who care for IPW in Chimborazo, Pichincha provinces of Ecuador. We utilized a semi-structured interview guide including questions about the experiences and perceptions of HPs in delivering health care to IPW. The interviews were recorded, transcribed and subjected to thematic analysis in Spanish and translated for reporting.

RESULTS

We found disagreements and discrepancies in the Ecuadorian health service that led to the ignorance of indigenous cultural values. Common characteristics among the indigenous population such as illiteracy, low income and the age of pregnancy are important challenges for the health system. The gender approach highlights the enormous challenges: machismo, gender stereotypes and communication problems that IPWs face in accessing quality healthcare.

CONCLUSIONS

Understanding the diverse perspectives of IPW, acknowledging their human rights particularly those related to gender, has the potential to lead to more comprehensive and respectful health care delivery in Ecuador. Further, recognizing there is a gender and power differential between the provider and the IPW can lead to improvements in the quality of health care delivery and reproductive, maternal and child health outcomes.

Missed opportunities to improve food security for pregnant people: a qualitative study of prenatal care settings in Northern New England during the COVID-19 pandemic

Background

Food insecurity during pregnancy has important implications for maternal and newborn health. There is increasing commitment to screening for social needs within health care settings. However, little is known about current screening processes or the capacity for prenatal care clinics to address food insecurity among their patients. We aimed to assess barriers and facilitators prenatal care clinics face in addressing food insecurity among pregnant people and to identify opportunities to improve food security among this population.

Methods

We conducted a qualitative study among prenatal care clinics in New Hampshire and Vermont. Staff and clinicians engaged in food security screening and intervention processes at clinics affiliated with the Northern New England Perinatal Quality Improvement Network (NNEPQIN) were recruited to participate in key informant interviews. Thematic analysis was used to identify prominent themes in the interview data.

Results

Nine staff members or clinicians were enrolled and participated in key informant interviews. Key barriers to food security screening and interventions included lack of protocols and dedicated staff at the clinic as well as community factors such as availability of food distribution services and transportation. Facilitators of screening and intervention included a supportive culture at the clinic, trusting relationships between patients and clinicians, and availability of clinic-based and community resources.

Conclusion

Prenatal care settings present an important opportunity to identify and address food insecurity among pregnant people, yet most practices lack specific protocols for screening. Our findings indicate that more systematic processes for screening and referrals, dedicated staff, and onsite food programs that address transportation and other access barriers could improve the capacity of prenatal care clinics to improve food security during pregnancy.

Birth-Related Outcomes for Second Children Following Home Visiting Program Enrollment for New Parents of First Children

Introduction

Home visiting (HV) programs aim to promote child and family health through perinatal intervention. HV may benefit second children through improving subsequent pregnancy and birth outcomes. However, HV impacts on birth outcomes of second children have not been examined in a naturalistic setting.

Methods

Using data from Connecticut Nurturing Families Network (NFN) home visiting program of families enrolled from 2005 to 2015, we compared birth-related outcomes (birthweight, preterm birth, Cesarean section delivery, prenatal care utilization) of second children (n = 1758) to demographically similar propensity-score-matched families that were not enrolled in NFN (n = 5200). We examined whether the effects of NFN differed by maternal age, race and ethnicity, or visit attendance pattern.

Results

There was no program effect for the full sample. The effect of NFN did not differ by maternal age or visit attendance pattern but did differ by maternal race and ethnicity. Black women in NFN were more likely to receive adequate prenatal care during their second pregnancy (OR 1.05; 95% CI 1.01, 1.09) and Hispanic women in NFN were less likely to deliver by Cesarean section for their second birth (OR 0.97; 95% CI 0.94, 0.99), compared to Black and Hispanic women in the comparison group respectively. There was a protective program effect on prematurity of the second child (OR 0.92; 95% CI 0.85, 0.996) for women with a preterm first birth.

Discussion

These findings suggest that benefits of HV extend to subsequent birth-related outcomes for women from marginalized racial/ethnic groups. HV may help buffer some harmful social determinants of health.

Prevalence of oncogenic human papillomavirus in pregnant adolescents, association with colpocytological changes, risk factors and obstetric outcomes

PURPOSE

The authors aim to carry out an investigation on the impact of cervical oncogenic Human Papillomavirus (HPV) detection in pregnant adolescents, to clarify the prevalence and risk factors, considering the importance and lack of data on this topic in Brazil.

METHODS

A cross-sectional study was conducted with adolescents receiving prenatal care in a tertiary hospital in São Paulo, Brazil, with routine Pap smear and oncogenic HPV detection test in the uterine cervix. The authors sought to associate the results of these tests with demographic and obstetric variables.

RESULTS

A total of 303 pregnant adolescents whose mean age was 15.30 ± 1.22 years comprised the study subjects. The frequency of high-risk HPV cervical detection was 50.50%. Multivariate analysis revealed that a large number of partners in their lifetime (OR = 1.27) and having a religion (OR = 2.05) were risk factors for cervical detection of oncogenic HPV, while schooling appeared as a protective factor (OR = 0.85). There was an association between this detection and colpocytological alterations, reaching almost 30% of patients, but without association with obstetric and neonatal outcomes.

CONCLUSION

The prevalence found is one of the highest in Brazil and worldwide. A greater number of partners during their lifetime and having religion were detected as possible factors associated with cervical HPV detection. Detection of cervical HPV-DNA did not influence obstetric and neonatal outcomes. The findings of this study reinforce the need to implement educational measures capable of modifying the incidence of sexually transmitted infections in this population and capable of promoting adherence to HPV vaccination programs.

Pregnant Black Women and Emergency Department Utilization: Assessing Self-Reported Receipt of Prenatal Counseling

There is limited literature on emergency department (ED) use among pregnant women. In this article, we examined the associations between prenatal counseling with the use of the ED during pregnancy. In our cohort of Black women in the Metro Detroit area, we found that approximately 70.5% of the women had an ED visit at some point during pregnancy. In unadjusted models of prevalence ratios, we found women reporting receipt of prenatal counseling regarding fetal movement, what to do about baby's movement slowing down, and smoking (but not what to do about smoking) were at statistically significantly greater risk of ED utilization during pregnancy. Adjustment for confounders slightly weakened the associations for counseling about baby's movement or smoking, so that the associations were no longer statistically significant. These findings call for further research on ED utilization among this population, especially differentiating urgent versus non-urgent use of the ED during pregnancy.

Maternal antibiotic exposure during pregnancy is a risk factor for community-acquired urinary tract infection caused by extended-spectrum beta-lactamase-producing bacteria in infants

BACKGROUND

This study aimed to investigate the risk factors for community-acquired urinary tract infection (UTI) caused by extended-spectrum beta-lactamase (ESBL)-positive bacteria in infants.

METHODS

We retrospectively reviewed the medical records of infants aged < 1 year with first UTI from 2018 to 2019 at two tertiary centers in Korea. Data analyzed included clinical findings, birth history, delivery mode, milk type, use of postpartum care center, and previous use of antibiotics both in the patient and mother.

RESULTS

Of 265 patients, 62 (23.4%) were diagnosed with first UTI caused by ESBL-positive bacteria at the median age of 3.6 (interquartile range (IQR) 2.3-5.4) months. Maternal use of antibiotics during pregnancy (29.0 vs. 10.3%, p < 0.001) and Klebsiella species (19.4% vs. 4.9%, p < 0.001) were significantly associated with ESBL-positive UTIs and remained valid in the multivariate analysis (odds ratio [OR], 3.40; 95% confidence interval [CI] 1.61-7.19, p = 0.001, and OR 5.26; 95% CI 2.03-13.13, p = 0.001, respectively). Previous antibiotic exposure of patients, previous hospitalization, prematurity, delivery mode, milk type, and use of postpartum care center were not significantly different between ESBL-positive and ESBL-negative groups. With respect to the clinical course of UTI, the ESBL-positive group presented a higher number of blood leukocytes (p = 0.041) and longer hospital stay (p < 0.001) than the ESBL-negative group.

CONCLUSIONS

About one-fourth of infantile UTI cases were ESBL-positive. Prenatal antibiotic exposure of mothers and Klebsiella species were associated with community-acquired UTI caused by ESBL-positive bacteria.

Perspectives on Maternal Vaccination from Obstetrical Clinicians: A Qualitative Multi-site Study

OBJECTIVES

Despite the seriousness of influenza and pertussis, availability of safe and effective vaccines against them, and long-standing maternal vaccination recommendations, US maternal influenza and Tdap vaccination rates have been low. To increase vaccination rates in obstetric offices, it is important to understand clinician perspectives and office processes. We conducted in-depth interviews with nurses and providers on these topics.

METHODS

Interviewees worked in obstetric offices in one-of-four participating health systems in NY and CA. We audio-recorded and transcribed 20-30-min interviews. We used predetermined categories to code interviews with Dedoose, then iteratively refined codes and identified themes.

RESULTS

We conducted 20 interviews between 4/2020 and 9/2020: 13 providers (physician or nurse midwife) (5 NY, 8 CA); 7 office nurses (6 NY, 1 CA). In almost all offices, patient refusal of influenza vaccine was considered the major vaccination barrier; Tdap was often deferred by patients until post-delivery. Nurse-only visits for either vaccine were rare. Vaccination outside the office was uncommon; few offices systematically documented vaccines given elsewhere in a retrievable manner. Participants emphasized patient education as key to prenatal care, but the number of topics left little time for immunizations. Few interviewees could identify an office "immunization champion," knew their office vaccination rates, or had participated in vaccination quality improvement. Several interviewees indicated that they or another provider were good at persuading hesitant patients, but their method had not been shared with other clinicians.

CONCLUSIONS FOR PRACTICE

Multiple practical barriers and maternal vaccine hesitancy limit maternal vaccination. Quality improvement strategies are needed.

Distance matters: barriers to antenatal care and safe childbirth in a migrant population on the Thailand-Myanmar border from 2007 to 2015, a pregnancy cohort study

BACKGROUND

Antenatal care and skilled childbirth services are important interventions to improve maternal health and lower the risk of poor pregnancy outcomes and mortality. A growing body of literature has shown that geographic distance to clinics can be a disincentive towards seeking care during pregnancy. On the Thailand-Myanmar border antenatal clinics serving migrant populations have found high rates of loss to follow-up of 17.4%, but decades of civil conflict have made the underlying factors difficult to investigate. Here we perform a comprehensive study examining the geographic, demographic, and health-related factors contributing to loss to follow-up.

METHODS

Using patient records we conducted a spatial and epidemiological analysis looking for predictors of loss to follow-up and pregnancy outcomes between 2007 and 2015. We used multivariable negative binomial regressions to assess for associations between distance travelled to the clinic and birth outcomes (loss to follow-up, pregnancy complications, and time of first presentation for antenatal care.) RESULTS: We found distance travelled to clinic strongly predicts loss to follow-up, miscarriage, malaria infections in pregnancy, and presentation for antenatal care after the first trimester. People lost to follow-up travelled 50% farther than people who had a normal singleton childbirth (a ratio of distances (DR) 1.5; 95% confidence interval (CI): 1.4 - 1.5). People with pregnancies complicated by miscarriage travelled 20% farther than those who did not have miscarriages (DR: 1.2; CI 1.1-1.3), and those with Plasmodium falciparum malaria in pregnancy travelled 60% farther than those without P. falciparum (DR: 1.6; CI: 1.6 - 1.8). People who delayed antenatal care until the third trimester travelled 50% farther compared to people who attended in the first trimester (DR: 1.5; CI: 1.4 - 1.5).

CONCLUSIONS

This analysis provides the first evidence of the complex impact of geography on access to antenatal services and pregnancy outcomes in the rural, remote, and politically complex Thailand-Myanmar border region. These findings can be used to help guide evidence-based interventions to increase uptake of maternal healthcare both in the Thailand-Myanmar region and in other rural, remote, and politically complicated environments.

Physician Referrals During Prenatal Care

OBJECTIVE

Referrals are an important component of patient care, and have been increasing over time. During pregnancy, people have intensive contact with the healthcare system, but little is known about the involvement of different physicians for pregnant patients during this period. This study examines referral patterns during prenatal care visits.

METHODS

Using the 2006-2015 National Ambulatory Medical Care Survey and national birth certificate data, we estimate the number of referrals per pregnancy from prenatal care visits with OB/GYN and family medicine physicians. We use multivariable regression analysis to compare the probability of receiving a referral during a prenatal visit for visits with family medicine and OB/GYN physicians, controlling for visit, patient, and physician characteristics. Analyses are weighted to make results nationally representative.

RESULTS

224,335,436 prenatal visits over 19,893,015 pregnancies were included; 60% of these visits were covered by private insurance. On average, 0.3 referrals are made per pregnancy (95% confidence interval [CI] 0.22, 0.38). A prenatal visit with an OB was 5.5% points less likely to result in a referral than a visit with a family medicine physician, controlling for other characteristics.

CONCLUSIONS

Referrals are relatively common in prenatal care, and are more commonly initiated by family medicine physicians than by OB/GYNs. Understanding the contribution of multiple clinicians to a pregnant person's health during the prenatal period and how coordination among clinicians impacts care receipt is an important next step. As healthcare becomes more specialized, better understanding care teams of individuals during the perinatal period is important for improving prenatal care.

Group prenatal care and improved birth outcomes: Results from a type 1 hybrid effectiveness-implementation study

To compare birth outcomes for patients receiving Expect With Me (EWM) group prenatal care or individual care only, we conducted a type 1 hybrid effectiveness-implementation trial (Detroit and Nashville, 2014-2016). Participants entered care <24 weeks gestation, had singleton pregnancy, and no prior preterm birth (N = 2402). Mean participant age was 27.1 (SD = 5.77); 49.5% were Black; 15.3% were Latina; 59.7% publicly insured. Average treatment effect of EWM compared to individual care only was estimated using augmented inverse probability weighting (AIPW). This doubly-robust analytic method produces estimates of causal association between treatment and outcome in the absence of randomization. AIPW was effective at creating equivalent groups for potential confounders. Compared to those receiving individual care only, EWM patients did significantly better on three of four primary outcomes: lower risk of infants born preterm (<37 weeks gestation; 6.4% vs. 15.1%, risk ratio (RR) 0.42, 95% Confidence Interval (CI) 0.29, 0.54), low birthweight (<2500 g; 4.3% vs. 11.6%, RR 0.37, 95% CI 0.24, 0.49), and admission to NICU (9.4% vs. 14.6%, RR 0.64, 95% CI 0.49, 0.78). There was no difference in small for gestational age (<10% percentile of weight for gestational age). EWM patients attended a mean of 5.9 group visits (SD = 2.7); 70% attended ≥5 group visits. Post-hoc analyses indicated EWM patients utilizing the integrated information technology platform had lower risk for low birthweight infants (RR 0.47, 95% CI 0.24, 0.86) than non-users. Future research is needed to understand mechanisms by which group prenatal care improves outcomes, best practices for implementation, and health systems savings.

Beyond BMI: Pregnancy-related weight stigma increases risk of gestational diabetes

The objective of this research brief was to assess if prenatal weight stigma is a predictive factor for perinatal complications compared to pre-pregnancy body mass index (BMI). Data were assessed from 358 women. Results indicated weight stigma concerns increased the odds of gestational diabetes, with a stronger association than BMI.

Asking About Childhood Adversity in the Prenatal Care Setting: Cross-Sectional Associations with Maternal Health and Mental Health Outcomes

OBJECTIVES

Adverse childhood experiences (ACEs) are associated with poor physical and mental health outcomes in pregnancy, prompting many care agencies to ask about ACEs as part of routine care. However, limited research has been conducted in the clinical setting to demonstrate associations between ACEs and maternal health (i.e., pregnancy complications and birth outcomes) and mental health in pregnancy (i.e., depression, anxiety, and substance use). The aims of the current study were to: (1) examine the prevalence of ACEs reported by patients attending a maternity clinic for medically low-risk patients, and (2) evaluate whether these reports were associated with prenatal health and mental health.

METHODS

Participants included pregnant women (n = 338) receiving prenatal care at a low-risk outpatient medical clinical from June 2017 to December 2018. Total ACE scores, pregnancy complications (e.g., gestational hypertension, preeclampsia), birth outcomes (e.g., Apgar scores, preterm birth), and mental health outcomes (i.e., anxiety, depression, and substance use) were extracted from electronic medical records.

RESULTS

The majority of women (67.8%) reported experiencing no ACEs, 16.0% reported one ACE, 10.1% reported two ACEs, and 6.2% reported three or more ACEs. ACEs were associated with increased odds of prenatal depression, anxiety, and substance use in a dose-response fashion, but not pregnancy health or birth outcomes.

CONCLUSIONS FOR PRACTICE

Prevalence rates of maternal ACEs obtained in the prenatal care setting were low compared to the general population. While ACEs were positively associated with maternal mental health and substance use in pregnancy, they were not associated with pregnancy complications.

"They Make You Feel Less of a Human Being": Understanding and Responding to Milwaukee's Racial Disparity in Infant Mortality

BACKGROUND

Black infants die three times as often as white and Hispanic infants before their first birthday in Milwaukee, WI. Prematurity is the major cause of infant mortality, and social determinants of health contribute to this disparity.

OBJECTIVES

To understand how socioeconomic factors and racism create barriers to healthy pregnancies and birth outcomes for Black women, and identify practices necessary for overcoming these barriers.

METHODS

Thirteen collaborators (four women, four support group leaders, and five health professionals) were recruited from church support groups, a family medicine residency clinic, and the health department. Data were collected through field observations, six one-on-one interviews, one small group interview, and one focus group.

RESULTS

Thematic analysis identified six key themes related to socioeconomic factors and racism in women's and infant health: Public Apathy; Violence and Stress; Discrimination; Mistrust; Spiritual and Social Support; Reproductive Justice.

CONCLUSIONS FOR PRACTICE

These themes point out failures in health care, social services, and policy initiatives that do not meet women's and infant needs, in addition to some opportunities to implement successful practices. Recommendations are made for policymakers, social services, health systems, and health professionals to implement systemic changes that support Black women and their families. Future applications of this work include implementing and measuring the impact of systems change to benefit Black women and families.

Syphilis testing adherence among women with livebirth deliveries: Indianapolis 2014-2016

BACKGROUND

The number of congenital syphilis (CS) cases in the United States are increasing. Effective prevention of CS requires routine serologic testing and treatment of infected pregnant women. The Centers for Disease Control and Prevention (CDC) recommends testing all pregnant women at their first prenatal visit and subsequent testing at 28 weeks gestation and delivery for women at increased risk.

METHODS

We conducted a cross-sectional cohort study of syphilis testing among pregnant women with a livebirth delivery from January 2014 to December 2016 in Marion County, Indiana. We extracted and linked maternal and infant data from the vital records in a local health department to electronic health records available in a regional health information exchange. We examined syphilis testing rates and factors associated with non-testing among women with livebirth delivery. We further examined these rates and factors among women who reside in syphilis prevalent areas.

RESULTS

Among 21260 pregnancies that resulted in livebirths, syphilis testing in any trimester, including delivery, increased from 71.7% in 2014 to 86.6% in 2016. The number of maternal syphilis tests administered only at delivery decreased from 16.6% in 2014 to 4.04% in 2016. Among women living in areas with high syphilis rates, syphilis screening rates increased from 79.6% in 2014 to 94.2% in 2016.

CONCLUSION

Improvement in prenatal syphilis screening is apparent and encouraging, yet roughly 1-in-10 women do not receive syphilis screening during pregnancy. Adherence to recommendations set out by CDC improved over time. Given increasing congenital syphilis cases, the need for timely diagnoses and prevention of transmission from mother to fetus remains a priority for public health.

Effects of the First 1000 Days Program, a systems-change intervention, on obesity risk factors during pregnancy

BACKGROUND

First 1000 Days is a systems-oriented program starting in early pregnancy lasting through the first 24 months of infancy focused on preventing obesity and related risk factors among low income, mother-infant pairs. The program was developed in partnership with stakeholders to create an infrastructure for system-wide change. It includes screening for adverse health behaviors and socio-contextual factors, patient navigation and educational materials to support behavior change and social needs, and individualized health coaching for women at highest risk of obesity and has been shown to reduce excess gestational weight gain for women who were overweight at the start of their pregnancy. The purpose of this study was to examine changes from the first to third trimester for women participating in the First 1000 Days Program.

METHODS

We collected information through self-administered questionnaires during the first and third trimester of gestation and from electronic health records relating to obesity risk factors. Measures collected included behavior (i.e., diet, physical activity and screen time) and psychosocial (i.e., anxiety) outcomes, as well as enrollment in Women, Infant, and Children (WIC) program. We examined the extent to which participation in the program was associated with changes in behaviors and psychosocial outcomes among women during pregnancy.

RESULTS

Women completed surveys at their initial and third trimester prenatal visits (n = 264). Mean age (SD) was 30.2 (5.51) years and 75% had an annual household income of <$50,000. Mean pre-pregnancy body mass index (BMI) was 27.7 kg/m2 and 64% started pregnancy with a BMI ≥ 25 kg/m2. In multivariable adjusted models, we observed decreases in intake of sugary-drinks (- 0.95 servings/day; 95% CI: - 1.86, - 0.03) and in screen time (- 0.21 h/day; 95% CI: - 0.40, - 0.01), and an increase in physical activity (0.88 days/week; 95% CI: 0.52, 1.23) from the first to third trimester. We also observed a decrease in pregnancy-related anxiety score (- 1.06 units; 95% CI: - 1.32, - 0.79) and higher odds of enrollment in Women, Infant, and Children (WIC) program (OR: 2.58; 95% CI: 1.96, 3.41).

CONCLUSIONS

Our findings suggest that a systems-oriented prenatal intervention may be associated with improvements in behaviors and psychosocial outcomes during pregnancy among low-income mothers.
