The content of prenatal care

Randomized comparison of a reduced-visit prenatal care model enhanced with remote monitoring

BACKGROUND

Standard prenatal care, consisting of 12-14 visits per pregnancy, is expensive and resource intensive, with limited evidence supporting the structure, rhythm, or components of care. Some studies suggest a reduced-frequency prenatal care model is as safe as the standard model of care for low-risk pregnant women, but evidence is limited. We developed and evaluated an innovative, technology-enhanced, reduced prenatal visit model (OB Nest).

OBJECTIVE

To evaluate the acceptability and effectiveness of OB Nest, a reduced-frequency prenatal care model enhanced with remote home monitoring devices and nursing support.

STUDY DESIGN

A single-center randomized controlled trial, composed of pregnant women, aged 18-36 years, recruited from an outpatient obstetric tertiary academic center in the Midwest United States. OB Nest care consisted of 8 onsite appointments with an obstetric provider; 6 virtual visits consisting of phone or online communication with an assigned nurse, supplemented with fetal Doppler and sphygmomanometer home monitoring devices; and access to an online community of pregnant women. Usual care consisted of 12 prescheduled prenatal clinic appointments with obstetric providers. Acceptability of OB Nest was measured by validated surveys of patient satisfaction with care at 36 weeks; perception of stress at 14, 24, and 36 weeks; and perceived quality of care at 36 weeks of gestation. Effectiveness was analyzed by comparing adherence to the American College of Obstetricians and Gynecologists recommended routine prenatal and ancillary services, maternal and fetal safety outcomes, and healthcare utilization.

RESULTS

Three hundred pregnant women at <13 weeks of gestation were recruited and randomized to OB Nest or usual care (150 in each arm) using a minimization algorithm. Demographic characteristics were similar between groups. Compared to usual care, patients in OB Nest had higher satisfaction on a 100-point validated modified Littlefield and Adams Satisfaction scale (OB Nest = 93.9% vs usual care = 78.9%, P < .01). Pregnancy-related stress, measured, on a 0-2 point PreNatal Maternal Stress validated scale, with higher scores indicating higher levels of stress, was lower among OB Nest participants at 14 weeks (OB Nest = 0.32 vs usual care = 0.41, P < .01) and at 36 weeks of gestation (OB Nest = 0.34 vs usual care = 0.40, P < .03). There was no statistical difference in perceived quality of care. Adherence to the provision of American College of Obstetricians and Gynecologists prenatal services was similar in both arms. Maternal and fetal clinical outcomes were similar between groups. Total reported nursing time was higher in OB Nest (OB Nest = 171.2 minutes vs usual care = 108.2 minutes, 95% confidence interval, 48.7-77.4).

CONCLUSION

OB Nest is an innovative, acceptable, and effective reduced-frequency prenatal care model. Compared to routine prenatal care, OB Nest resulted in higher patient satisfaction and lower prenatal stress, while reducing the number of appointments with clinicians and maintaining care standards for pregnant women. This program is a step toward evidence-driven prenatal care that improves patient satisfaction.

Prevalence and maternal characteristics associated with receipt of prenatal care provider counseling about medications safe to take during pregnancy

Use of some medications during pregnancy can be harmful to the developing fetus, and discussion of the risks and benefits with prenatal care providers can provide guidance to pregnant women. We used Pregnancy Risk Assessment Monitoring System data collected for 2015 births aggregated from 34 US states (n = 40,480 women) to estimate the prevalence of self-reported receipt of prenatal care provider counseling about medications safe to take during pregnancy. We examined associations between counseling and maternal characteristics using adjusted prevalence ratios (aPR). The prevalence of counseling on medications safe to take during pregnancy was 89.2% (95% confidence interval [CI]: 88.7-89.7). Women who were nulliparous versus multiparous (aPR 1.03; 95% CI: 1.02-1.04), who used prescription medications before pregnancy versus those who did not, (aPR 1.03; 95% CI: 1.02-1.05), and who reported having asthma before pregnancy versus those who did not, (aPR 1.05; 95% CI: 1.01-1.08) were more likely to report receipt of counseling. There was no difference in counseling for women with pre-pregnancy diabetes, hypertension, and/or depression compared to those without. Women who entered prenatal care after the first trimester were less likely to report receipt of counseling (aPR 0.93; 95% CI: 0.91-0.96). Overall, self-reported receipt of counseling was high, with some differences by maternal characteristics. Although effect estimates were small, it is important to ensure that information is available to prenatal care providers about medication safety during pregnancy, and that messages are communicated to women who are or might become pregnant.

The Reproductive Years of Women with Perinatally Acquired HIV: From Gynecologic Care to Obstetric Outcomes

Women with PHIV have distinct medical and social concerns in the context of lifelong immunosuppression, complex HIV care, and stigma because of with HIV from an early age. This article reviews the gynecologic and obstetric concerns experienced by women with PHIV. Cervical cancer screening is suboptimal, and data suggest higher rates of unintended pregnancy. Pregnant women with PHIV are younger and exposed to more antiretroviral therapy regimens compared with women with NPHIV. Although obstetric outcomes are similar between women with PHIV and NPHIV, there are concerns that infant morbidity may be increased in infants of women with PHIV.

Use of wearable sensors for pregnancy health and environmental monitoring: Descriptive findings from the perspective of patients and providers

Background

Wearable sensors and other smart technology may be especially beneficial in providing remote monitoring of sub-clinical changes in pregnancy health status. Yet, limited research has examined perceptions among pregnant patients and providers in incorporating smart technology into their daily routine and clinical practice.

Objective

The purpose of this study was to examine the perceptions of pregnant women and their providers at a rural health clinic on the use of wearable technology to monitor health and environmental exposures during pregnancy.

Methods

An anonymous 21-item e-survey was administered to family medicine or obstetrics and gynecology (n=28) providers at a rural health clinic; while a 21-item paper survey was administered to pregnant women (n=103) attending the clinic for prenatal care.

Results

Smartphone and digital technology use was high among patients and providers. Patients would consider wearing a mobile sensor during pregnancy, reported no privacy concerns, and felt comfortable sharing information from these devices with their physician. About seven out of 10 women expressed willingness to change their behavior during pregnancy in response to receiving personalized recommendations from a smartphone. While most providers did not currently use smart technologies in their medical practice, about half felt it will be used more often in the future to diagnose and remotely monitor patients. Patients ranked fetal heart rate and blood pressure as their top preference for health monitoring compared to physicians who ranked blood pressure and blood glucose. Patients and providers demonstrated similar preferences for environmental monitoring, but patients as a whole expressed more interests in tracking environmental measures compared to their providers.

Conclusions

Patients and providers responded positively to the use of wearable sensor technology in prenatal care. More research is needed to understand what factors might motivate provider use and implementation of wearable technology to improve the delivery of prenatal care.

Applying the chronic care model to prenatal care: Patient activation, productive interactions, and prenatal outcomes

OBJECTIVE

To demonstrate how the chronic care model can be applied in prenatal care.

METHODS

This study was conducted through analysis of data generated in the women's health and family medicine departments of one community hospital and two medical centers across three states (Georgia, Nevada, and Virginia). 159 low-risk obstetric patients were monitored throughout their pregnancy for patient activation and biometric measures including: blood pressure at each appointment, baby's gestational age at birth, and mode of delivery. Patient activation was assessed with the validated, licensed patient activation measure.

RESULTS

Patient activation was strongly associated with the Prenatal Interpersonal Processes of Care metric (F (2, 155) = 3.41, p < .05). Also, increased age, decreased Prenatal Interpersonal Processes of Care, fewer pregnancies, and increased diastolic blood pressure were associated with an increased likelihood of cesarean delivery and the model correctly predicted 81% of cases.

CONCLUSION

Women who identified as feeling more activated reported more positive pregnancy experiences, and women who reported more positive pregnancy experiences were more likely to experience a vaginal delivery.

PRACTICE IMPLICATIONS

Activated patients, more positive prenatal experience, and improved delivery outcomes can be achieved through applying the chronic care model.

Improving Prenatal Care for Minority Women

Since the inception of prenatal care in the early 1900s, the focus of care has been on risk reduction rather than on health promotion. Prenatal care began as individualized care, but more recently group prenatal care has been shown to be very successful in improving birth outcomes. For all women, an emphasis on improving health behaviors is important at this critical time while women are engaging regularly with the healthcare system. An emphasis on mental health promotion may decrease some of the disparities in birth outcomes that are well documented between minority and majority women, as minority women are known to experience increased levels of stress, anxiety, and depression. Providing support for pregnant women and incorporating knowledge and skills through prenatal care may promote both physical and mental health in minority women.

Implementation of a new prenatal care model to reduce office visits and increase connectivity and continuity of care: protocol for a mixed-methods study

Background

Most low-risk pregnant women receive the standard model of prenatal care with frequent office visits. Research suggests that a reduced schedule of visits among low-risk women could be implemented without increasing adverse maternal or fetal outcomes, but patient satisfaction with these models varies. We aim to determine the effectiveness and feasibility of a new prenatal care model (OB Nest) that enhances a reduced visit model by adding virtual connections that improve continuity of care and patient-directed access to care.

Methods and design

This mixed-methods study uses a hybrid effectiveness-implementation design in a single center randomized controlled trial (RCT). Embedding process evaluation in an experimental design like an RCT allows researchers to answer both “Did it work?” and “How or why did it work (or not work)?” when studying complex interventions, as well as providing knowledge for translation into practice after the study. The RE-AIM framework was used to ensure attention to evaluating program components in terms of sustainable adoption and implementation.

Low-risk patients recruited from the Obstetrics Division at Mayo Clinic (Rochester, MN) will be randomized to OB Nest or usual care. OB Nest patients will be assigned to a dedicated nursing team, scheduled for 8 pre-planned office visits with a physician or midwife and 6 telephone or online nurse visits (compared to 12 pre-planned physician or midwife office visits in the usual care group), and provided fetal heart rate and blood pressure home monitoring equipment and information on joining an online care community.

Quantitative methods will include patient surveys and medical record abstraction. The primary quantitative outcome is patient-reported satisfaction. Other outcomes include fidelity to items on the American Congress of Obstetricians and Gynecologists standards of care list, health care utilization (e.g. numbers of antenatal office visits), and maternal and fetal outcomes (e.g. gestational age at delivery), as well as validated patient-reported measures of pregnancy-related stress and perceived quality of care. Quantitative analysis will be performed according to the intention to treat principle. Qualitative methods will include interviews and focus groups with providers, staff, and patients, and will explore satisfaction, intervention adoption, and implementation feasibility. We will use methods of qualitative thematic analysis at three stages. Mixed methods analysis will involve the use of qualitative data to lend insight to quantitative findings.

Discussion

This study will make important contributions to the literature on reduced visit models by evaluating a novel prenatal care model with components to increase patient connectedness (even with fewer pre-scheduled office visits), as demonstrated on a range of patient-important outcomes. The use of a hybrid effectiveness-implementation approach, as well as attention to patient and provider perspectives on program components and implementation, may uncover important information that can inform long-term feasibility and potentially speed future translation.

A qualitative study of gestational weight gain counseling and tracking

Excessive gestational weight gain (GWG) predicts adverse pregnancy outcomes and later obesity risk for both mother and child. Women who receive GWG advice from their obstetric clinicians are more likely to gain the recommended amount, but many clinicians do not counsel their patients on GWG, pointing to the need for new strategies. Electronic medical records (EMRs) are a useful tool for tracking weight and supporting guideline-concordant care, but their use for care related to GWG has not been evaluated. We performed in-depth interviews with 16 obstetric clinicians from a multi-site group practice in Massachusetts that uses an EMR. We recorded, transcribed, coded, and analyzed the interviews using immersion-crystallization. Many respondents believed that GWG had "a lot" of influence on pregnancy and child health outcomes but that their patients did not consider it important. Most indicated that excessive GWG was a big or moderate problem in their practice, and that inadequate GWG was rarely a problem. All used an EMR feature that calculates total GWG at each visit. Many were enthusiastic about additional EMR-based supports, such as a reference for recommended GWG for each patient based on pre-pregnancy body mass index, a "growth chart" to plot actual and recommended GWG, and an alert to identify out-of-range gains, features which many felt would remind them to counsel patients about excessive weight gain. Additional decision support tools within EMRs would be well received by many clinicians and may help improve the frequency and accuracy of GWG tracking and counseling.

Differences in quality of antenatal care provided by midwives to low-risk pregnant dutch women in different ethnic groups

INTRODUCTION

The objective of this study was to evaluate whether differences existed in the adherence to the Dutch national guidelines regarding basic antenatal care by Dutch midwives for low-risk women of different ethnic groups.

METHODS

This was an observational study using data from electronic antenatal charts of 7 midwife practices (23 midwives), participating in the Generation R Study. The Generation R Study is a multiethnic, population-based, prospective, cohort study that is investigating the growth, development, and health of urban children from fetal life until young adulthood. The study is conducted in Rotterdam, The Netherlands. The antenatal charts of 2093 low-risk pregnant women with an expected birthing date in 2002 through 2004 were used to determine the mean quality of antenatal care scores for 7 ethnic groups. These scores reflected the degree of adherence to the guidelines regarding 10 tests and examinations.

RESULTS

Few differences between ethnic groups were found in adherence to the guidelines that addressed the obstetric-technical quality of antenatal care. This finding applied more to nulliparous than to multiparous women. Adherence to guidelines was not always better in the antenatal care provided to native Dutch multiparous women when compared to other ethnic groups. Midwives adhered well to the guidelines regarding most tests. For all women, irrespective of ethnic background, hemoglobin was not measured as often as recommended, and this was especially the case for Moroccan, Surinamese-Creole, and Dutch-Antillean multiparous women.

DISCUSSION

The poorer adherence regarding screening for hemoglobin needs further investigation, as women with African or Mediterranean heritage are more at risk for hemoglobinopathies. However, in general, midwives adhered well to the clinical guidelines regarding most tests irrespective of the ethnic background of the pregnant women. When differences were present, these were not systematically less favorable for non-Dutch pregnant women.

Management of cannabis use during pregnancy: an assessment of healthcare professionals' practices

PURPOSE

Because of the increase of cannabis use, healthcare professionals are more and more confronted with pregnancies which have been exposed to this drug. There may be health consequences during the course of pregnancy and also for the babies throughout their development. We have made a study in order to evaluate practices of detection and care for pregnant women who use cannabis.

METHODS

A questionnaire was sent to all gynaecologists (GYNs), obstetricians (OBs) and midwives (MWs) in the district of Loire-Atlantique and to a 20% randomized sample of general practitioners (GPs).

RESULTS

The participation rate was 60.1%. Only 51.4% of healthcare professionals asked their patients about drugs use and 68.1% didn't feel informed enough about the risks of cannabis use during pregnancy. There was a significant difference between the healthcare professionals who deliver babies (OBs and MWs) and those who only do prenatal consultations (GYNs and GPs). The first group question their patients about the use of cannabis more often (69.1% versus 39.8%; p = 0.01), and also feel more informed about the risks of cannabis use during pregnancy (42.0% versus 24.4%; p = 0.025).

CONCLUSIONS

Healthcare professionals who supervise childbirth have a more accurate perception of the risk related to the consumption of cannabis during pregnancy. But preventive action must be taken early on because the lack of early identification at the beginning of pregnancy represents a public health problem. After observing the results we feel there is a strong need for training for all practitioners.

A critical appraisal of guidelines for antenatal care: components of care and priorities in prenatal education

There are a variety of published prenatal care (PNC) guidelines that claim a scientific basis for the information included. Four sets of PNC guidelines published between 2005 and 2009 were examined and critiqued. The recommendations for assessment procedures, laboratory testing, and education/counseling topics were analyzed within and between these guidelines. The PNC components were synthesized to provide an organized, comprehensive appendix that can guide providers of antepartum care. The appendix may be used to locate which guidelines addressed which topics to assist practitioners to identify evidence sources. The suggested timing for introducing and reinforcing specific topics is also presented in the appendix. Although education is often assumed to be a vital component of PNC, it was inconsistently included in the guidelines that were reviewed. Even when education was included, important detail was lacking. Addressing each woman's needs as the first priority was suggested historically and remains relevant in current practice to systematically provide care while maintaining the woman as the central player. More attention to gaps in current research is important for the development of comprehensive prenatal guidelines that contribute effectively to the long-term health and well-being of women, families, and their communities.

Introduction of CenteringPregnancy in a public health clinic

CenteringPregnancy is a promising group visit prenatal care innovation that provides substantial health promotion content. Elements unique to group care include peer support and self-management training and activities. CenteringPregnancy was introduced at a large public health clinic serving predominantly low-income African American pregnant women. All prenatal care at this clinic was provided by certified nurse-midwives, and all providers were trained in the CenteringPregnancy model. One hundred and ten women received prenatal care in CenteringPregnancy groups. Focus groups of pregnant women, providers, and health center staff reported that the program benefited women despite implementation challenges such as scheduling changes. Compared to women in individual care, women in CenteringPregnancy had significantly more prenatal visits, increased weight gain, increased breast feeding rates, and higher overall satisfaction. This pilot project demonstrated that CenteringPregnancy can be implemented in a busy public health clinic serving predominantly low-income pregnant women and is associated with positive health outcomes.

Postpartum mothers' attitudes, knowledge, and trust regarding vaccination

OBJECTIVE

To examine attitudes and knowledge about vaccinations in postpartum mothers.

METHODS

This cross-sectional study collected data via written survey to postpartum mothers in a large teaching hospital in Connecticut. We used multivariable analysis to identify mothers who were less trusting with regard to vaccines.

RESULTS

Of 228 mothers who participated in the study, 29% of mothers worried about vaccinating their infants: 23% were worried the vaccines would not work, 11% were worried the doctor would give the wrong vaccine, and 8% worried that "they" are experimenting when they give vaccines. Mothers reported that the most important reasons to vaccinate were to prevent disease in the baby (74%) and in society (11%). Knowledge about vaccination was poor; e.g., 33% correctly matched chicken pox with varicella vaccine. Mothers who were planning to breastfeed (P=.01), were primiparous (P=.01), or had an income<$40,000 but did not receive support from the women, infants, and children (WIC) program were less trusting with regard to vaccines (P=.03). Although 70% wanted information about vaccines during pregnancy, only 18% reported receiving such information during prenatal care.

CONCLUSION

Although the majority of infants receive vaccines, their mothers have concerns and would like to receive immunization information earlier. Mothers who are primiparous, have low family incomes but do not qualify for the WIC program, or are breastfeeding may need special attention to develop a trusting relationship around vaccination. Mothers would benefit from additional knowledge regarding the risks and benefits of vaccines particularly during prenatal care.
