Addressing maternal and child health equity through a community health worker home visiting intervention to reduce low birth weight: retrospective quasi-experimental study of the Arizona Health Start Programme.

ABSTRACT:

Objective

To test if participation in the Health Start Programme, an Arizona statewide Community Health Worker (CHW) maternal and child health (MCH) home visiting programme, reduced rates of low birth weight (LBW), very LBW (VLBW), extremely LBW (ELBW) and preterm birth (PTB).

Design

Quasi-experimental retrospective study using propensity score matching of Health Start Programme enrolment data to state birth certificate records for years 2006-2016.

Setting

Arizona is uniquely racially and ethnically diverse with comparatively higher proportions of Latino and American Indian residents and a smaller proportion of African Americans.

Participants

7212 Health Start Programme mothers matched to non-participants based on demographic, socioeconomic and geographic characteristics, health conditions and previous birth experiences.

Intervention

A statewide CHW MCH home visiting programme.

Primary and secondary outcome measures

LBW, VLBW, ELBW and PTB.

Results

Using Health Start Programme's administrative data and birth certificate data from 2006 to 2016, we identified 7212 Health Start Programme participants and 53 948 matches. Programme participation is associated with decreases in adverse birth outcomes for most subgroups. Health Start participation is associated with statistically significant lower rates of LBW among American Indian women (38%; average treatment-on-the-treated effect (ATT): 2.30; 95% CI -4.07 to -0.53) and mothers with a pre-existing health risk (25%; ATT: -3.06; 95% CI -5.82 to -0.30). Among Latina mothers, Health Start Programme participation is associated with statistically significant lower rates of VLBW (36%; ATT: 0.35; 95% CI -0.69 to -0.01) and ELBW (62%; ATT: 0.31; 95% CI (-0.52 to -0.10)). Finally, Health Start Programme participation is associated with a statistically significant lower rate of PTB for teen mothers (30%; ATT: 2.81; 95% CI -4.71 to -0.91). Other results were not statistically significant.

Conclusion

A state health department-operated MCH home visiting intervention that employs CHWs as the primary interventionist may contribute to the reduction of LBW, VLBW, ELBW and PTB and could improve birth outcomes statewide, especially among women and children at increased risk for MCH inequity.

Project description:BACKGROUND:Maternal depression is common among low-income women enrolled in home visiting programs, yet there is considerable variability in the extent to which it is identified and addressed. This study examines outcomes related to postpartum depression screening, receipt of evidence-based services, and reductions in depressive symptoms among clients of home visiting programs in the Health Resources and Services Administration's Maternal, Infant, and Early Childhood Home Visiting Program Home Visiting Collaborative Improvement and Innovation Network (HV CoIIN), the first U.S. national application of the Institute for Healthcare Improvement's Breakthrough Series (BTS) Model in home visiting programs. METHODS AND FINDINGS:Fourteen home visiting programs in eight states, serving a geographically and racially diverse caseload of pregnant women and new mothers, took part in the HV CoIIN. Women in participating home visiting programs received the intervention strategies implemented by their program during participation in the collaborative. HV CoIIN strategies included specific policies and protocols for depression screening and home visitor response to screening results; home visitor training and supervision; delivery of prevention and treatment interventions; and tracking systems for screening, referral, and follow-up. HV CoIIN's proposed primary outcome was that 85% of women who accessed evidence-based services would experience a 25% reduction in depressive symptoms three months after accessing services. Secondary outcomes included an increased percentage of women who were screened for depression within three months of enrollment or birth, who verbally accepted a referral to evidence-based services, and who received one or more evidence-based service contacts. HV CoIIN resulted in improved symptoms among women who accessed services, from 51.1% to 59.9%. HV CoIIN also improved the percent of women screened for depression, from 83.6% to 96.3%, and those with positive depression screens who accessed evidence-based services, from 41.6% to 65.5%. Home visiting programs in this study were early adopters of quality improvement activities, which may limit the generalizability of these results to other home visiting programs. CONCLUSIONS:Home visiting programs can play an important role in closing gaps in maternal depression identification, referrals, service access, and symptom alleviation. Continuous quality improvement and BTS collaborative methods can be used to improve home visiting services in ways that advance national public health priorities and improve population health outcomes.

Project description:BackgroundUnderstanding the mechanisms of implementation of public health interventions in community settings is a key aspect of programme assessments. To determine core components and establish a programme theory are important tools to improve functioning and support dissemination of programme models to new locations. An extended early childhood home visiting intervention has been developed on-site in a socioeconomically disadvantaged area of Sweden since 2013 with the aim of reducing persisting health inequities in the population. This study aimed at investigating the core programme components and how the intervention was perceived to contribute towards health equity from early childhood.MethodsQualitative framework method was applied in a document analysis and subsequent semi-structured interviews with 15 key actors involved in the programme.ResultsThe intervention was found to be constituted of five core components centred around the situation-based, parental strengthening work method delivered by a qualified team of child health care nurse and social worker. The programme theory foresaw positive effects on child and parental health, responsive parenting practices, families' use of welfare services according to need and increased integration and participation in society. The principles of Proportionate Universalism were recognised in the programme theory and the intervention was perceived as an important contribution to creating conditions for improved health equity for the families. Still, barriers to health equity were identified on the structural level which limit the potential impact of the programme.ConclusionsThe core components of the Extended home visiting programme in Rinkeby correspond well to those of similar evidence-based home visiting interventions. Combining focus on early childhood development and responsive parenting with promoting access to the universal welfare services and integration into society are considered important steppingstones towards health equity. However, a favourable macro-political environment is required in the endeavour to balance the structural determinants' influence on health inequities. Improved availability and accessibility to welfare services that respond to the needs of the families regarding housing, education and employment are priorities.Trial registrationThe study was retrospectively registered on 11/08/2016 in the ISRCTN registry ( ISRCTN11832097 ).

Project description:BackgroundMultisectoral and public-private partnerships are critical in building the necessary infrastructure, policy, and political will to ameliorate health inequity. A focus on health equity by researchers, practitioners, and decision-makers prioritizes action to address the systematic, avoidable, and unjust differences in health status across population groups sustained over time and generations that are beyond the control of individuals. Health equity requires a collective process in shaping the health and wellbeing of the communities in which we live, learn, work, play, and grow. This paper explores multisectoral leaders' understanding of the social, environmental, and economic conditions that produce and sustain health inequity in northern Arizona, a geographically expansive, largely rural, and culturally diverse region.MethodsData are drawn from the Southwest Health Equity Research Collaborative's Regional Health Equity Survey (RHES). The RHES is a community-engaged, cross-sectional online survey comprised of 31 close-ended and 17 open-ended questions. Created to assess cross-sectoral regional and collective capacity to address health inequity and inform multisectoral action for improving community health, the RHES targeted leaders representing five rural northern Arizona counties and 13 sectors. Select open-ended questions were analyzed using an a priori coding scheme and emergent coding with thematic analysis.ResultsAlthough leaders were provided the definition and asked to describe the root causes of inequities, the majority of leaders described social determinants of health (SDoH). When leaders described root causes of health inequity, they articulated systemic factors affecting their communities, describing discrimination and unequal allocation of power and resources. Most leaders described the SDoH by discussing compounding factors of poverty, transportation, housing, and rurality among others, that together exacerbate inequity. Leaders also identified specific strategies to address SDoH and advance health equity in their communities, ranging from providing direct services to activating partnerships across organizations and sectors in advocacy for policy change.ConclusionOur findings indicate that community leaders in the northern Arizona region acknowledge the importance of multisectoral collaborations in improving health equity for the populations that they serve. However, a common understanding of health equity remains to be widely established, which is essential for conducting effective multisectoral work to advance health equity.

Project description:BackgroundThe health visitors' role in many countries is changing. In Scotland, the role has undergone substantial changes through the introduction of an enhanced health visiting programme, which includes increased, structured home visits. This evaluation was conducted within NHS Ayrshire and Arran, one of the 14 Scottish Health Boards. Our aim was to understand and explain how, and why, the programme could contribute to improving health and wellbeing outcomes for children and families.MethodsWe used a realist evaluation approach, conducted in three phases. In phase one, eight managerial staff involved in developing and implementing the programme provided data, which were used to develop initial programme theories. In phase two, the programme theories were tested using qualitative data from 25 health visitors and 22 parents. The programme theories were refined through analyses and interpretation of data in phase three.ResultsThe home visiting context provided by the programme interacted with the mechanisms of the programme and produced outcomes such as early identification of health and wellbeing issues amongst families who needed more support, leading to referral and engagement with sources of additional help. The home visits facilitated development of parent-health visitor relationships, and parents considered health visitors as their first point of contact on children's wellbeing and developmental-related issues. Moreover, the programme provided more clarity to health visitors' role, which in turn enhanced partnership working. However, there were aspects of the programme that may require further development. For instance, both parents and health visitors were concerned about the wide gaps between some home visits.ConclusionsThe enhanced health visiting programme increased opportunities for monitoring and early identification of health and wellbeing concerns. It created structures for a more efficient partnership working and ensured that the needs of children and families were supported. These benefits need to be evaluated further in an effectiveness study.

Project description:Despite their growing popularity, little is known about how cash transfers (CTs) can affect health equity in targeted communities. Lesotho's Child Grants Programme (CGP) is an unconditional CT targeting poor and vulnerable households with children. Started in 2009, the CGP is one of Lesotho's key programmes in developing the country's social protection system. Using the CGP's early phases as a case study, this research aims to capture how programme stakeholders understood and operationalized the concept of health equity in Lesotho's CGP. The qualitative analysis relied on the triangulation of findings from a desk review and semi-structured key informant interviews with programme stakeholders. The programme documents were coded deductively and the interview transcripts inductively. Both materials were analysed thematically before triangulating their findings. We explored determining factors for differences or disagreements within a theme according to the programme's chronology, the stakeholders' affiliations and their role(s) in the CGP. The definitions of health equity in the context of the CGP reflected an awareness among stakeholders of these issues and their determinants but also the challenges raised by the complex (or even debated) nature of the concept. The most common definition of this concept focused on children's access to health services for the most disadvantaged households, suggesting a narrow, targeted approach to health equity as targeting disadvantages. Yet, even the most common definition of this concept was not fully translated into the programme, especially in the day-to-day operations and reporting at the local level. This operationalization gap affected the study of selected health spillover effects of the CGP on health equity and might have undermined other programme impacts related to specific health disadvantages or gaps. As equity objectives become more prominent in CTs, understanding their meaning and translation into concrete, observable and measurable applications in programmes are essential to support impact.
