Systematic review of economic evaluation studies on preconception care interventions.

Implementation of preconception care interventions have been encouraged for improving maternal and child health outcomes; therefore, evidence on their cost-effectiveness is needed. We conducted the systematic review to examine the efficiency of those interventions by collecting evidence from published economic evaluation studies. Out of 14 included studies, almost all (12/14) were in high-income countries. All studies were not cost-utility analysis with genetic disease screening and diabetes management were the common interventions for evaluating their efficiency during preconception period. Preconception care interventions are likely to be cost-effective, especially in low-income countries which incremental benefits had a greater return than developed nations.

Preconception health in England: a proposal for annual reporting with core metrics.

There is growing interest in preconception health as a crucial period for influencing not only pregnancy outcomes, but also future maternal and child health, and prevention of long-term medical conditions. Successive national and international policy documents emphasise the need to improve preconception health, but resources and action have not followed through with these goals. We argue for a dual intervention strategy at both the public health level (eg, by improving the food environment) and at the individual level (eg, by better identification of those planning a pregnancy who would benefit from support to optimise health before conception) in order to raise awareness of preconception health and to normalise the notion of planning and preparing for pregnancy. Existing strategies that target common risks factors, such as obesity and smoking, should recognise the preconception period as one that offers special opportunity for intervention, based on evidence from life-course epidemiology, developmental (embryo) programming around the time of conception, and maternal motivation. To describe and monitor preconception health in England, we propose an annual report card using metrics from multiple routine data sources. Such a report card should serve to hold governments and other relevant agencies to account for delivering interventions to improve preconception health.

Effect of preconception low dose aspirin on pregnancy and live birth according to socioeconomic status: A secondary analysis of a randomized clinical trial.

Low socioeconomic status (SES) is associated with adverse pregnancy outcomes and infertility. Low-dose aspirin (LDA) was shown to improve livebirth rates in certain subsets of women, and therefore, may impact pregnancy rates differentially by SES status. Therefore, the aim of the current study was to examine whether daily preconception-initiated LDA affects rates of pregnancy, livebirth, and pregnancy loss differently across strata of socioeconomic status (SES). This is a secondary analysis of The Effects of Aspirin in Gestation and Reproduction (EAGeR) Trial, a multisite, block- randomized, placebo-controlled trial conducted at four U.S. medical centers (n = 1,228, 2007-2012). Women attempting spontaneous conception with a history of pregnancy loss were randomly allocated preconception to 81mg of aspirin + 400mcg of folic acid (n = 615) or placebo + 400mcg of folic acid (n = 613). Study medication was administered for six menstrual cycles or until 36 weeks' gestation if pregnancy was achieved. For this analysis, women were stratified by SES, which included income (low, mid, high) and a combined grouping of education and income (low-low, low-high, high-low, high-high). Log binomial models with robust variance estimated risks of pregnancy, livebirth, and pregnancy loss for LDA versus placebo. LDA increased pregnancy and livebirth rates (RR 1.23, 95% CI: 1.03, 1.45) in the high-income, but not mid- or low-income groups. LDA increased pregnancy rates in both the low education-low income group (RR 1.22, 95% CI: 1.02, 1.46) and the high education-high income group (RR 1.23, 95%CI: 1.06, 1.42), with no effect observed in mid-SES groupings. LDA, a low-cost and widely available treatment, may be particularly beneficial to women at the highest and lowest ends of the socioeconomic spectrum, though underlying mechanisms of this disparity are unclear. Confirming these findings and identifying factors which may modulate the effectiveness of LDA will ultimately facilitate personalized clinical care and improvements in population-level reproductive health.

A systematic review of women's and health professional's attitudes and experience of preconception care service delivery.

BACKGROUND: The value and importance of preconception care (PCC) have been acknowledged by leading health organizations as a vital element within preventive medicine and health promotion for the wider population. The translation of PCC from position statement to relevant service and programme delivery is essential for the benefits of PCC to be realized and relies on insights from health services research. This article aims to review contemporary health services research literature examining women's and health professionals' perceptions and experiences of PCC services. METHODS: A systematic review of original research published between 2003 and 2015 was conducted in November 2015. Multiple databases (PubMed, CINAHL, AMED and Maternity and Infant Care) were searched through two distinct searches to capture research literature reporting the perspective of health professionals and women towards PCC service delivery. RESULTS: The search identified 13 papers (4 reported the perceptions of women, 11 described the views of health professionals [2 papers reported findings from both groups]). The analyses of the contemporary literature revealed five broad areas of focus: women's service needs regarding PCC, PCC training and education requirements, role delineation around PCC, priority and value of PCC and barriers and obstacles to PCC. CONCLUSIONS: Despite the mounting evidence supporting the value and importance of PCC, there is insufficient research attention given to the clinical reality of PCC service and programme delivery. The transfer of PCC guidelines from broad policy to grass roots practice requires a more detailed consideration of the practicalities of implementing PCC within contemporary women's health care.

Does a strategy to promote shared decision-making reduce medical practice variation in the choice of either single or double embryo transfer after in vitro fertilisation? A secondary analysis of a randomised controlled trial.

OBJECTIVES: The hypothesis that shared decision-making (SDM) reduces medical practice variations is increasingly common, but no evidence is available. We aimed to elaborate further on this, and to perform a first exploratory analysis to examine this hypothesis. This analysis, based on a limited data set, examined how SDM is associated with variation in the choice of single embryo transfer (SET) or double embryo transfer (DET) after in vitro fertilisation (IVF). We examined variation between and within hospitals. DESIGN: A secondary analysis of a randomised controlled trial. SETTING: 5 hospitals in the Netherlands. PARTICIPANTS: 222 couples (woman aged <40 years) on a waiting list for a first IVF cycle, who could choose between SET and DET (ie, ≥2 embryos available). INTERVENTION: SDM via a multifaceted strategy aimed to empower couples in deciding how many embryos should be transferred. The strategy consisted of decision aid, support of IVF nurse and the offer of reimbursement for an extra treatment cycle. Control group received standard IVF care. OUTCOME MEASURE: Difference in variation due to SDM in the choice of SET or DET, both between and within hospitals. RESULTS: There was large variation in the choice of SET or DET between hospitals in the control group. Lower variation between hospitals was observed in the group with SDM. Within most hospitals, variation in the choice of SET or DET appeared to increase due to SDM. Variation particularly increased in hospitals where mainly DET was chosen in the control group. CONCLUSIONS: Although based on a limited data set, our study gives a first insight that including patients' preferences through SDM results in less variation between hospitals, and indicates another pattern of variation within hospitals. Variation that results from patient preferences could be potentially named the informed patient rate. Our results provide the starting point for further research. TRIAL REGISTRATION NUMBER: NCT00315029; Post-results.

Fulfilling an Unmet Need: Roles for Clinical Pharmacists in Preconception Care.

Preconception care refers to a set of interventions that identify and address biomedical, behavioral, and social risks to a woman's health that may negatively impact a future pregnancy. A great need for preconception care currently exists in the United States, and women's attitudes about discussions with health care providers about healthy and safe pregnancies are positive. Clinical pharmacists are well positioned to work with other health care and public health professionals to ensure that all women of childbearing potential have access to preconception care. As part of the collaborative health care team, clinical pharmacists can directly provide services or support and referrals to other members of the health care team or to community resources through clinical-community linkages. Specifically, clinical pharmacists can provide education, counseling, and/or services to women to address family planning, medication and disease state management, immunizations, screenings, health promotion, and substance use. Clinical pharmacists can also impact preconception care through drug information services, advocacy, and research. Preconception care services can be incorporated into daily pharmacy practice, and there are potential means for reimbursement. Multiple roles exist for clinical pharmacists to fulfill unmet needs in preconception care.

Preventable health and cost burden of adverse birth outcomes associated with pregestational diabetes in the United States.

OBJECTIVE: Preconception care for women with diabetes can reduce the occurrence of adverse birth outcomes. We aimed to estimate the preconception care (PCC)-preventable health and cost burden of adverse birth outcomes associated with diagnosed and undiagnosed pregestational diabetes mellitus (PGDM) in the United States. STUDY DESIGN: Among women of reproductive age (15-44 years), we estimated age- and race/ethnicity-specific prevalence of diagnosed and undiagnosed diabetes. We applied age and race/ethnicity-specific pregnancy rates, estimates of the risk reduction from PCC for 3 adverse birth outcomes (preterm birth, major birth defects, and perinatal mortality), and lifetime medical and lost productivity costs for children with those outcomes. Using a probabilistic model, we estimated the reduction in adverse birth outcomes and costs associated with universal PCC compared with no PCC among women with PGDM. We did not assess maternal outcomes and associated costs. RESULTS: We estimated 2.2% of US births are to women with PGDM. Among women with diagnosed diabetes, universal PCC might avert 8397 (90% prediction interval [PI], 5252-11,449) preterm deliveries, 3725 (90% PI, 3259-4126) birth defects, and 1872 (90% PI, 1239-2415) perinatal deaths annually. Associated discounted lifetime costs averted for the affected cohort of children could be as high as $4.3 billion (90% PI, 3.4-5.1 billion) (2012 US dollars). PCC among women with undiagnosed diabetes could yield an additional $1.2 billion (90% PI, 951 million-1.4 billion) in averted cost. CONCLUSION: Results suggest a substantial health and cost burden associated with PGDM that could be prevented by universal PCC, which might offset the cost of providing such care.

Ashkenazi Jewish population screening for Tay-Sachs disease: the international and Australian experience.

Internationally, Tay-Sachs disease (TSD) preconception screening of Ashkenazi Jewish (AJ) individuals and couples has led to effective primary prevention of TSD. In Australia, adolescent preconception genetic screening programs operate mainly in Jewish community high schools. These existing programs offer an effective means of primary prevention of TSD, are cost effective and safe. However, in the broader Australian community TSD screening is not systematically performed and cases still occur in unscreened AJ individuals. In order to improve the effectiveness of Australian screening, there is a need for definitive guidelines for healthcare professionals to facilitate extension of the proven benefits of preconception TSD screening to all AJ individuals at risk. We performed a systematic review of the relevant literature relating to AJ pre-conception and antenatal screening for TSD. The evidence was assessed using an established National Health and Medical Research Council evidence grading system. Evaluations of efficacy of TSD screening programs design and execution, cost-benefit and cost-utility health economic evaluation, and population outcomes were undertaken. The results have been used to propose a model for universal AJ TSD preconception and antenatal screening for the primary care setting.

Preconception care: advancing from 'important to do and can be done' to 'is being done and is making a difference'.

There is a growing evidence base for preconception care--the provision of biomedical, behavioral and social interventions to women and couples before conception occurs. Firstly, there is evidence that health problems, problem behaviours and individual and environmental risks contribute to poor maternal and child health outcomes. Secondly, there are biomedical, behavioural and social interventions that when delivered beforeconception occurs, effectively address many of these health problems, problem behaviours and risk factors.And thirdly, there is emerging experience of how to deliver these interventions in low and middle income countries (LMIC).The preconception care interventions delivered and whom they are delivered to, will need to be tailored to local realities. The package of preconception care interventions delivered in a particular setting will depend on the local epidemiology, the interventions already being delivered, and the resources in place to deliver additionalinterventions. Although a range of population groups could benefit from preconception care, prioritization based on need and feasibility will be needed.There are both potential benefits and risks associated with preconception care. Preconception care could result in large health and social benefits in LMIC. It could also be misused to limit the autonomy of women and reinforce the notion that the focus of all efforts to improve the health of girls and women should be at improving maternal and child health outcomes rather than at improving the health of girls and women as individuals in their own right.There are challenges in delivering preconception care. While the potential benefits of preconception care programmes could be substantial, extending the traditional Maternal and Child Health package will be both a logistic and financial challenge.We need to help countries set and achieve pragmatic and meaningful short term goals. While our longterm goal for preconception care should be for a full package of health and social interventions to be delivered to all women and couples of reproductive age everywhere, our short-term goals must be pragmatic. This is because countries that need preconception care most are the ones least likely to be able to afford them and deliver them.If we want these countries to take on the additional challenge of providing preconception care while they struggle to increase the coverage of prenatal care, skilled care at birth etc., we must help them identify and deliver a small number of effective interventions based on epidemiology and feasibility.

Free preconceptual screening examination service in rural areas of Hubei Province, China in 2012.

OBJECTIVE: This work aims to collect and summarize the outcomes on free preconceptual screening examination in rural areas of Hubei Province in 2012. Moreover, this review promotes further understanding of the status of this activity to provide the Family Planning Commission valid scientific data upon which to construct effective policies. METHODS: Couples, who complied with the family planning policy and were the residents in agricultural areas or lived in a local rural area for more than six months, were encouraged to participate in the free preconceptual screening examination service provided by the Hubei Provincial Population and Family Planning Commission. This service included 19 screening tests. All the data, including forms, manuals, and test results, were collected from 1 January 2012 to 31 December 2012 in rural areas in Hubei Province. RESULTS: A total of 497,860 individuals participated in the free preconceptual screening examination service, with a coverage rate of 97.1%. 4.0% and 4.8% of the participants exhibited with abnormal blood levels of ALT and creatinine, respectively; 0.36% of the participants tested positive for syphilis; 0.44% and 3.6% of the female participants tested positive for Neisseria gonorrhoeae and Chlamydia trachomatis, respectively; and 0.84% and 1.8% of the female participants tested positive for cytomegalovirus (IgM) and Toxoplasma gondii (IgM), respectively. After risk assessment, 59,935 participants might have high-risk of adverse pregnancy outcomes. In 2012, the prevalence of birth defects among the parturient who participated in the preconceptual screening examination service was 0.04%, while the prevalence was 0.08% among those who did not participate in the service. CONCLUSION: Preconceptual screening examination service may help to address the risk factors that can lead to adverse pregnancy outcome. More studies on the relationship between preconceptual screening examination service and prevalence of birth defect or other adverse pregnancy outcomes should be conducted.

Wisconsin's Lifecourse Initiative for Healthy Families: application of the maternal and child health life course perspective through a regional funding initiative.

National experts are calling for more integrated approaches such as the life course perspective to reduce health disparities and achieve greater health equity. The translation and application of the life course perspective is therefore of great interest to public health planners, policy makers and funders to promote community-wide improvements in maternal and child health. However, few organizations have applied the life course perspective in designing strategic funding initiatives. For over three decades, Wisconsin has observed persistent racial disparities in birth outcomes. This complex public health issue led to the development of the Lifecourse Initiative for Health Families, a regional multi-million dollar funding initiative created and supported by the Wisconsin Partnership Program of the University of Wisconsin School of Medicine and Public Health (Created by the UW SMPH from an endowment following the conversion of Blue Cross Blue Shield United of Wisconsin, the Partnership Program makes investments in research, education, and public health and prevention initiatives that improve health and reduce health disparities in the state.). Over a 2-year period, the program funded four collaboratives to adopt a life course perspective and develop strategic plans for improving African American birth outcomes. The Twelve-point plan to close the black-white gap in birth outcomes provided the framework for the planning process. Despite the conceptual challenges, the life course perspective was embraced by the collaboratives, challenged community assumptions on the root causes of poor birth outcomes and provided a unifying funding construct for organizing and planning complementary individual-level interventions with social and physical environmental change strategies. These integrated and complimentary approaches provide a long-term opportunity to address the persistent racial birth outcome disparity in Wisconsin.

Providing general and preconception health care to low income women in family planning settings: perception of providers and clients.

This study examines both provider and client perceptions of the extent to which general health concerns are addressed in the context of publicly supported family planning care. A mail survey of family planning providers (n = 459) accepting Medicaid-covered clients in Arkansas and Alabama gathered data on reported actions and resource referral availability for ten categories of non-contraceptive health concerns. A telephone survey of recent family planning clients of these providers (n = 1991) gathered data on the presence of 16 health concerns and whether and how they were addressed by the family planning provider. Data were collected in 2006-2007. More than half (56%) of clients reported having one or more general health concerns. While 43% of those concerns had been discussed with the family planning providers, only 8% had been originally identified by these providers. Women with higher trust in physicians and usual sources of general health care were more likely to discuss their concerns. Of those concerns discussed, 39% were reportedly treated by the family planning provider. Similarly, over half of responding providers reported providing treatment for acute and chronic health conditions and counseling on health behaviors during family planning visits. Lack of familiarity with referral resources for uninsured clients was identified as a significant concern in the provision of care to these clients. Greater engagement by providers in identifying client health concerns and better integration of publicly supported family planning with other sources of health care for low income women could expand the existing potential for delivering preconception or general health care in these settings.

Preconception health of low socioeconomic status women: assessing knowledge and behaviors.

INTRODUCTION: The stalled U.S. infant mortality rate and persistent disparities in adverse pregnancy outcomes may be addressed by optimizing a woman's health throughout her childbearing years. This study examines women's knowledge and behaviors related to preconception risk factors in two community health centers serving lower income, racially diverse populations. METHODS: A survey was administered among a convenience sample of women ages 18 to 44 years (n = 340). Questions focused on health behaviors and conditions, knowledge of risk factors, and recommendations of health care providers. Outcomes include the prevalence of risk factors and correlations between the presence of a risk factor and either a respondent's knowledge or a health care provider's recommendation. Data were analyzed for total respondents and two subgroups: Black, non-Hispanic and Hispanic. RESULTS: Despite strong knowledge of risk factors in the preconception period, high-risk behaviors and conditions existed: 63% of women overweight or obese, 20% drinking alcohol, and 42% taking a multivitamin. Significant differences in risk factors were noted between Black, non-Hispanic and Hispanic respondents. Overweight/obesity (t = 3.0; p < .05) and alcohol use (χ² = 9.2; p < .05) were higher among Black, non-Hispanics, whereas Hispanic women had lower rates of multivitamin use (χ² = 11.1; p < .05). The majority of respondents recall being spoken to by a health care provider about pregnancy-related risks. Most risk factors were not influenced by provider's recommendations, including multivitamin use, drinking alcohol, and smoking. However, birth control use was correlated with a provider's recommendation (χ² = 7.6; p < .05). Correlations between the presence of risk factors and respondent's knowledge existed for immunizations (χ² = 9.6; p < .05), but not for multivitamin use, drinking alcohol, or smoking. CONCLUSION: Our study identified behaviors amenable to change. Knowledge alone or a doctor's recommendation are not enough to change those behaviors. Innovative programs and support systems are required to encourage women to adopt healthy behaviors throughout the childbearing years.

Stillbirths: what difference can we make and at what cost?

Worldwide, 2·65 million (uncertainty range 2·08 million to 3·79 million) stillbirths occur yearly, of which 98% occur in countries of low and middle income. Despite the fact that more than 45% of the global burden of stillbirths occur intrapartum, the perception is that little is known about effective interventions, especially those that can be implemented in low-resource settings. We undertook a systematic review of randomised trials and observational studies of interventions which could reduce the burden of stillbirths, particularly in low-income and middle-income countries. We identified several interventions with sufficient evidence to recommend implementation in health systems, including periconceptional folic acid supplementation or fortification, prevention of malaria, and improved detection and management of syphilis during pregnancy in endemic areas. Basic and comprehensive emergency obstetric care were identified as key effective interventions to reduce intrapartum stillbirths. Broad-scale implementation of intervention packages across 68 countries listed as priorities in the Countdown to 2015 report could avert up to 45% of stillbirths according to a model generated from the Lives Saved Tool. The overall costs for these interventions are within the general estimates of cost-effective interventions for maternal care, especially in view of the effects on outcomes across maternal, fetal, and neonatal health.

Preconception care for women with diabetes: is it effective and who should provide it?

The association between hyperglycaemia and congenital malformations was first recognised over 40 years ago and was followed by the development of preconception clinics for women with diabetes. A fresh look at preconception care is needed as many studies were conducted during the late 1970s and early 1980s, before the introduction of regular home blood glucose monitoring and glycosylated haemoglobin assays, and when many patients with diabetes had microvascular complications. Recent observational studies and a meta-analysis suggest preconception care is effective with an approximately threefold reduction in the risk of malformations. There is now a worldwide epidemic of type 2 diabetes, but only few studies of preconception care have included women with type 2 diabetes. Furthermore, few studies have addressed the relationship between preconception care and perinatal morbidity. This article will review the evidence for preconception care in women with diabetes, evaluate different models of preconception care and discuss future strategies.
