Systematic review: An exploration of core componentry characterizing effective sustained nurse home visiting programs

Abstract

Aims: To identify the core components or potential 'active ingredients' of sustained nurse home visiting (SNHV) programs that have demonstrated positive effects on maternal or child health, psychosocial development, or self-sufficiency outcomes among disadvantaged families in high-income countries.

Design: Systematic review with narrative summary.

Data sources: Programs were identified from searches of several reputable evidence clearing houses and the following bibliographic databases: Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, and Cochrane Central Register of Controlled Trials. Year of publication was originally restricted from 2008 -2018, with additional searches conducted up to 2019.

Review methods: This review of SNHV program componentry builds on a previous evaluation of program effectiveness. Programs were selected for inclusion if they had been tested in a randomized or cluster-randomized controlled trial (RCT/CRCT). Componentry characteristics related to program delivery, nurse provider, and outcome-specific intervention content were then extracted.

Results: Comparison of the seven eligible programs showed seven common core components: antenatal commencement, support to child age 2 years, at least 19 scheduled visits and experienced or highly qualified nurses with program-specific training, caseloads of approximately 25 families, regular supervision, and multidisciplinary supports. Outcome-specific program content was generally not well reported.

Conclusion: The findings from this review have utility in guiding the development of minimum standard benchmarks and best-practice recommendations for SNHV programs and call for more detailed publication of core content componentry in the SNHV literature.

Impact: Identification of the core componentry underpinning program effectiveness should inform policy decisions on program selection, adaptation for specific populations, and quality control. Such evidence-based decision-making should in turn lead to better maternal and child outcomes among disadvantaged families in high-income countries, reducing societal and economic burdens of inequity.
