Maternal and perinatal health research priorities beyond 2015 : an international survey and prioritization exercise

Background: Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the 2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required. Methods. We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international stakeholders constituting a large reference group, and consolidated into a final list of research questions by a technical working group. Questions on this list were then scored by the reference working group according to five independent and equally weighted criteria. Normalized research priority scores (NRPS) were calculated, and research priority questions were ranked accordingly. Results: A list of 190 priority research questions for improving maternal and perinatal health was scored by 140 stakeholders. Most priority research questions (89%) were concerned with the evaluation of implementation and delivery of existing interventions, with research subthemes frequently concerned with training and/or awareness interventions (11%), and access to interventions and/or services (14%). Twenty-one questions (11%) involved the discovery of new interventions or technologies. Conclusions: Key research priorities in maternal and perinatal health were identified. The resulting ranked list of research questions provides a valuable resource for health research investors, researchers and other stakeholders. We are hopeful that this exercise will inform the post-2015 Development Agenda and assist donors, research-policy decision makers and researchers to invest in research that will ultimately make the most significant difference in the lives of mothers and babies.</p

Targeted health and social care interventions for women and infants who are disproportionately impacted by health inequalities in high-income countries: a systematic review

Background: Disadvantaged populations (such as women from minority ethnic groups and those with social complexity) are at an increased risk of poor outcomes and experiences. Inequalities in health outcomes include preterm birth, maternal and perinatal morbidity and mortality, and poor-quality care. The impact of interventions is unclear for this population, in high-income countries (HIC). The review aimed to identify and evaluate the current evidence related to targeted health and social care service interventions in HICs which can improve health inequalities experienced by childbearing women and infants at disproportionate risk of poor outcomes and experiences. Methods: Twelve databases searched for studies across all HICs, from any methodological design. The search concluded on 8/11/22. The inclusion criteria included interventions that targeted disadvantaged populations which provided a component of clinical care that differed from standard maternity care. Results: Forty six index studies were included. Countries included Australia, Canada, Chile, Hong Kong, UK and USA. A narrative synthesis was undertaken, and results showed three intervention types: midwifery models of care, interdisciplinary care, and community-centred services. These intervention types have been delivered singularly but also in combination of each other demonstrating overlapping features. Overall, results show interventions had positive associations with primary (maternal, perinatal, and infant mortality) and secondary outcomes (experiences and satisfaction, antenatal care coverage, access to care, quality of care, mode of delivery, analgesia use in labour, preterm birth, low birth weight, breastfeeding, family planning, immunisations) however significance and impact vary. Midwifery models of care took an interpersonal and holistic approach as they focused on continuity of carer, home visiting, culturally and linguistically appropriate care and accessibility. Interdisciplinary care took a structural approach, to coordinate care for women requiring multi-agency health and social services. Community-centred services took a place-based approach with interventions that suited the need of its community and their norms. Conclusion: Targeted interventions exist in HICs, but these vary according to the context and infrastructure of standard maternity care. Multi-interventional approaches could enhance a targeted approach for at risk populations, in particular combining midwifery models of care with community-centred approaches, to enhance accessibility, earlier engagement, and increased attendance.

Core outcomes for studies of pregnant women with multimorbidity : clinician focus group

Objective: A key aim of MuM-PreDiCT is to develop a core outcome set for studies of pregnant women and birthing people with pre-existing multimorbidity. This involves four stages: systematic literature search, focus groups, Delphi surveys and a consensus meeting. We present the findings from a focus group, exploring outcomes that clinicians feel should be measured. Method: One focus group was conducted online (2021, UK), with eight clinicians who care for pregnant women with multimorbidity. Participants were purposively sampled, with representation from obstetric/maternal medicine (n = 2), midwifery (2), obstetrics (1), neonatology (1), perinatal psychiatry (1), and general practice (1); England (7) and Scotland (1); ethnic minorities (6) and white ethnicity (2). Inductive thematic analysis was conducted. Results: Outcomes were categorised by maternal (22 themes) and children’s outcomes (10 themes), and health care utilisation (6 themes). Selected themes are presented here. Maternal outcomes in the pre-pregnancy period included fertility and the quality of preconception counselling. Pregnancy may influence women’s long-term health conditions and perinatal mental health. They may have limited options in birth, such as mode of birth and birth with no intervention. Care-related outcomes included whether there was shared decision making, multidisciplinary coordination and continuity of care throughout pregnancy; whether postnatal and long-term support was offered and its quality. Outcomes after birth included women’s capability as a mother, such as mother-infant bonding and establishing feeding. Clinicians wanted information on the effects of medication on child outcomes and women’s compliance with medications during and after pregnancy. It is important to measure the impact of stopping medication as suboptimal control of existing health conditions may affect the pregnancy and child. Child outcomes pertinent to patient counselling included the risk of congenital anomalies, neurodevelopmental outcomes, neonatal mortality and morbidity. Health care utilisation outcomes included the need for additional appointments, admission to hospital/intensive care and length of separation from baby after birth. Core outcomes specific to multimorbidity in pregnancy may need to focus more on patient reported experiential outcomes, for example women’s satisfaction with care. Other considerations included framing outcomes positively and measuring the differential association of maternal ethnicity with outcomes. Conclusions: Clinicians reported a range of outcomes important for studies of pregnant women with multimorbidity. After we have completed focus groups with women with multimorbidity and experience of, or are planning a pregnancy, we shall conduct a Delphi survey using the focus group outcomes to inform its design

Polypharmacy during pregnancy and associated risk factors:a retrospective analysis of 577 medication exposures among 1.5 million pregnancies in the UK, 2000-2019

BackgroundThe number of medications prescribed during pregnancy has increased over the past few decades. Few studies have described the prevalence of multiple medication use among pregnant women. This study aims to describe the overall prevalence over the last two decades among all pregnant women and those with multimorbidity and to identify risk factors for polypharmacy in pregnancy.MethodsA retrospective cohort study was conducted between 2000 and 2019 using the Clinical Practice Research Datalink (CPRD) pregnancy register.Prescription records for 577 medication categories were obtained. Prevalence estimates for polypharmacy (ranging from 2+ to 11+ medications) were presented along with the medications commonly prescribed individually and in pairs during the first trimester and the entire pregnancy period.Logistic regression models were performed to identify risk factors for polypharmacy.ResultsDuring the first trimester (812,354 pregnancies), the prevalence of polypharmacy ranged from 24.6% (2+ medications) to 0.1% (11+ medications). During the entire pregnancy period (774,247 pregnancies), the prevalence ranged from 58.7 to 1.4%.Broad-spectrum penicillin (6.6%), compound analgesics (4.5%) and treatment of candidiasis (4.3%) were commonly prescribed. Pairs of medication prescribed to manage different long-term conditions commonly included selective beta 2 agonists or selective serotonin re-uptake inhibitors (SSRIs).Risk factors for being prescribed 2+ medications during the first trimester of pregnancy include being overweight or obese [aOR: 1.16 (1.14–1.18) and 1.55 (1.53–1.57)], belonging to an ethnic minority group [aOR: 2.40 (2.33–2.47), 1.71 (1.65–1.76), 1.41 (1.35–1.47) and 1.39 (1.30–1.49) among women from South Asian, Black, other and mixed ethnicities compared to white women] and smoking or previously smoking [aOR: 1.19 (1.18–1.20) and 1.05 (1.03–1.06)]. Higher and lower age, higher gravidity, increasing number of comorbidities and increasing level of deprivation were also associated with increased odds of polypharmacy.ConclusionsThe prevalence of polypharmacy during pregnancy has increased over the past two decades and is particularly high in younger and older women; women with high BMI, smokers and ex-smokers; and women with multimorbidity, higher gravidity and higher levels of deprivation. Well-conducted pharmaco-epidemiological research is needed to understand the effects of multiple medication use on the developing foetus
