A systematic review of structured versus non-structured breastfeeding programmes to support the initiation and duration of exclusive breastfeeding in acute and primary healthcare settings.

Abstract

Background Breastfeeding has many important health benefits for the woman and her baby. Despite evidence of benefit from a large number of well conducted studies, breastfeeding uptake and the duration of exclusive breastfeeding remain low in many countries. In order to improve breastfeeding rates, policy and guidelines at global, individual country level and in local healthcare settings have recommended that structured programmes to support breastfeeding should be introduced. The objective of this review was to consider the evidence of outcomes of structured compared with non-structured breastfeeding programmes in acute maternity care settings to support initiation and duration of exclusive breastfeeding. Review methods The definition of structured programme used included a multi-faceted or single intervention approach to support breastfeeding; definition of non-structured included support offered within standard care. The review considered quantitative and qualitative studies which addressed outcomes following the introduction of a structured programme in acute healthcare settings to support breastfeeding compared with no programme. The primary outcomes of interest were uptake of breastfeeding and duration of exclusive breastfeeding (only breast milk, including milk expressed). Studies which only considered community based interventions were not included. Search strategy A search of the literature published between 1992 and 2010 was conducted, which followed a four step process. After a limited search of MEDLINE and CINAHL to identify key words contained in the title or abstract and index terms to describe relevant interventions, a second extensive search was undertaken using identified key words and index terms. The third step included a search of reference lists and bibliographies of relevant articles and the fourth step included a search of grey and unpublished literature and national databases Methodological quality Methodological quality was assessed using checklists developed by the Joanna Briggs Institute. Two independent reviewers conducted critical appraisal and data extraction. Results Twenty-six articles were included; one randomised controlled trial, two non randomised trials, one cross-sectional study, five systematic reviews, 15 cohort studies and two descriptive studies. Due to the poor quality of evidence presented and clinical and methodological heterogeneity of study designs, including definitions of breastfeeding and duration of follow-up, it was not possible to combine studies or individual outcomes in meta-analyses, therefore findings are presented in a narrative form. In most studies the structured programme of interest reflected some or all of the Baby Friendly Hospital Initiative ‘Ten Steps’. Most studies found a statistically significant improvement in initiation of breastfeeding following introduction of a structured breastfeeding programme, although effect sizes varied widely. The impact of introducing a structured programme on the duration of exclusive breastfeeding and duration of any breastfeeding was also evident, although not all studies found statistically significant differences. At hospital discharge or within the first week post-birth, implementation of a structured programme appeared to increase duration of exclusive breastfeeding and the duration of any breastfeeding compared with usual care. After hospital discharge and up to six months post-birth, use of structured programmes also appeared to support continued duration of exclusive and any breastfeeding although differences in outcomes were not reported across all included studies. At six months, three of five studies which included data on longer-term outcomes showed women were statistically significantly more likely to be exclusively breastfeeding. Only one of these studies compared outcomes following implementation of BFHI. Conclusions Despite the poor overall quality of studies, structured programmes, regardless of content, compared with standard care appear to influence the uptake and duration of exclusive breastfeeding and any breastfeeding. In healthcare settings with low breastfeeding uptake and duration rates, structured programmes may have a greater benefit. TRUNCATED AT 600 WORDS
