Perceptions of primary care-based breastfeeding promotion interventions: qualitative analysis of randomized controlled trial participant interviews

Lessons for the UK on implementation and evaluation of breastfeeding support: evidence syntheses and stakeholder engagement

Background

Breastfeeding impacts positively on multiple health outcomes, but < 50% of UK women breastfeed at 8 weeks. Women with long-term conditions face additional challenges in breastfeeding.

Objectives

To synthesise global and UK evidence to co-create an implementation and evaluation toolkit for cost-effective breastfeeding support in the NHS.

Design

Evidence syntheses with stakeholder engagement.

Review methods

Systematic reviews examined effectiveness of breastfeeding support for (1) healthy women and (2) women with long-term conditions using Cochrane Pregnancy and Childbirth Group methods. Mixed-methods systematic reviews synthesised process evaluations of effective breastfeeding support interventions for healthy women and experiences of receiving/providing support for breastfeeding women with long-term conditions. Cross-study synthesis integrated qualitative and quantitative findings. Systematic reviews synthesised evidence on the incremental costs and cost-effectiveness of breastfeeding support following National Institute for Health and Care Excellence guidance. All searches were conducted from May 2021 to October 2022. Stakeholder engagement and toolkit development comprised online discussions, a modified Delphi study, focus groups and four workshops. Participants were 23 stakeholders, 16 parents in the parents' panels, 15 women in the focus groups and 87 stakeholders who attended the workshops.

Results

We found considerably more interventions designed for healthy women (review 1) than aimed at women with long-term conditions (reviews 1 and 4); approximately half of the studies were targeted at groups at higher risk of poor breastfeeding outcomes, and the impact of support may be different in these populations. Despite this, studies from review 2 found that women perceived the provision of support as positive, important and needed. Studies from review 5 echoed a range of suggestions from participants regarding potential strategies to improve breastfeeding support, with the most widely reported being the need to acknowledge the role and influence of other sources of support (e.g. partners, family, friends, peers, external professionals, web-based resources) and involving these sources in the provision of breastfeeding support for women with long-term conditions. In reviews 3 and 6, there was uncertainty about the cost-effectiveness of breastfeeding support interventions due to the limited number of studies and lack of good-quality evidence.

Limitations

There was a lack of evidence for the effectiveness and cost-effectiveness of breastfeeding interventions in the UK. There was often insufficient information reported about intervention characteristics.

Conclusions

'Breastfeeding only' support probably reduces the number of women stopping any or exclusive breastfeeding. The evidence for 'breastfeeding plus' interventions is less consistent, but these may reduce the number of women stopping exclusive breastfeeding at 4-6 weeks and at 6 months. We found no evidence of differential intervention effects regarding mode of provision or provider. Cost-effectiveness is uncertain due to the lack of good-quality evidence. Key enablers of successful implementation were responsiveness and tailoring of interventions to both women's and supporters' needs. Breastfeeding support as delivered in the included studies probably has little to no effect on breastfeeding outcomes for women with long-term conditions. The mixed-methods synthesis and stakeholder work identified that existing interventions may not address the complex needs of these women. The main study output is a co-produced toolkit to guide implementation and evaluation of breastfeeding support services in the UK.

Future work

Evaluation of breastfeeding support for all women, particularly those at risk of poor breastfeeding outcomes (e.g. long-term conditions, deprivation). This could involve tailoring the toolkit to local contexts via implementation and effectiveness studies or using quality improvement studies.

Attitudes of mothers and health care providers towards behavioural interventions promoting breastfeeding uptake: A systematic review of qualitative and mixed-method studies

PURPOSE

Recommendations for exclusive breastfeeding are not often adhered to despite the robust evidence of its benefits. This systematic review aims to collate evidence on the attitudes mothers and health care providers have towards breastfeeding interventions to understand what aspects best contribute to acceptability and feasibility.

METHODS

This review further investigates the value of identifiable behaviour change techniques (BCTs) to uncover which components of an intervention are perceived to be most useful and acceptable. The main biomedical databases were searched, and 17 (n = 17) studies met the inclusion criteria.

RESULTS

A total of nine BCTs were identified within the interventions. The thematic analysis produced four main domains: usefulness, accessibility, value and sustainability. Women discussed the importance of the support they received in these interventions and demonstrated a positive view towards three BCTs: 'social support (unspecified)', 'instruction on how to perform behaviour' and 'demonstration of behaviour'. Additionally, women highlighted the benefit of personal, non-clinical and flexible emotional and practical support from peers, lactation consultants and support groups. Health care providers echoed these opinions and specifically highlighted the usefulness of interventions that allowed for continuity of care and more personal breastfeeding support.

CONCLUSIONS

These findings suggest that ongoing practical as well as emotional support is crucial for standard in-hospital support to succeed at increasing breastfeeding rates. Future research would need to better understand the nuances of the interventions among women and providers to enhance their implementation.

Parity and the Association Between Maternal Sociodemographic Characteristics and Breastfeeding

Objective: Although clinicians recognize the importance of breastfeeding for child health, breastfeeding initiation can be limited by maternal characteristics such as race/ethnicity, age at first birth, and educational attainment. We hypothesized that the strong influence of prior infant feeding experiences on multiparous women's decision to initiate and continue breastfeeding may mean that these maternal characteristics influence breastfeeding more strongly for primiparas than multiparas. Materials and Methods: Using Pregnancy Risk Assessment and Monitoring System (PRAMS) (Phase 8) survey data from 2016 to 2017, we analyzed mothers' responses to the supplemental question about parity, "Before you got pregnant with your new baby, did you ever have any other babies who were born alive?" Study variables were summarized by using weighted means and proportions and compared according to parity by using Wald tests. In the overall cohort, we evaluated the interaction between parity and each covariate by using logistic regression. Results: In our sample (N = 20,694), 40% of respondents were first-time mothers, and 88% had initiated breastfeeding. Primiparas were more likely to breastfeed than multiparas (92% versus 86%; p < 0.001), but they had shorter mean breastfeeding duration. On unadjusted analysis, four covariates were more strongly associated with breastfeeding initiation among primiparas than multiparas (maternal age, educational attainment, receiving breastfeeding information from a nurse or other medical professional, and receiving breastfeeding information from family or friends). Conclusions: Breastfeeding initiation is impacted more strongly by maternal characteristics for primiparas than multiparas.

Lactation Consultants' Perceived Barriers to Providing Professional Breastfeeding Support

BACKGROUND

Addressing suboptimal breastfeeding initiation and duration rates is a priority in the United States. To address challenges to improving these rates, the voices of the providers who work with breastfeeding mothers should be heard. Research aim: The purpose of this study was to explore lactation consultants' perceived barriers to managing early breastfeeding problems.

METHODS

This qualitative study was conducted with a grounded theory methodological approach. In-depth interviews were conducted with 30 International Board Certified Lactation Consultants across Florida. Lactation consultants were from a range of practice settings, including hospitals, Special Supplemental Nutrition Program for Women, Infants, and Children clinics, private practice, and pediatric offices. Data were digitally recorded, transcribed, and analyzed in Atlas.ti.

RESULTS

A range of barriers was identified and grouped into the following categories/themes: indirect barriers (social norms, knowledge, attitudes); direct occupational barriers (institutional constraints, lack of coordination, poor service delivery); and direct individual barriers (social support, mother's self-efficacy). A model was developed illustrating the factors that influence the role enactment of lactation consultants in managing breastfeeding problems.

CONCLUSION

Inadequate support for addressing early breastfeeding challenges is compounded by a lack of collaboration among various healthcare providers and the family. Findings provide insight into the professional management issues of early breastfeeding problems faced by lactation consultants. Team-based, interprofessional approaches to breastfeeding support for mothers and their families are needed; improving interdisciplinary collaboration could lead to better integration of lactation consultants who are educated and experienced in providing lactation support and management of breastfeeding problems.

ABM Clinical Protocol #19: Breastfeeding Promotion in the Prenatal Setting, Revision 2015

A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Effect of primary care intervention on breastfeeding duration and intensity

OBJECTIVES

We determined the effectiveness of primary care-based, and pre- and postnatal interventions to increase breastfeeding.

METHODS

We conducted 2 trials at obstetrics and gynecology practices in the Bronx, New York, from 2008 to 2011. The Provider Approaches to Improved Rates of Infant Nutrition & Growth Study (PAIRINGS) had 2 arms: usual care versus pre- and postnatal visits with a lactation consultant (LC) and electronically prompted guidance from prenatal care providers (EP). The Best Infant Nutrition for Good Outcomes (BINGO) study had 4 arms: usual care, LC alone, EP alone, or LC+EP.

RESULTS

In BINGO at 3 months, high intensity was greater for the LC+EP (odds ratio [OR] = 2.72; 95% confidence interval [CI] = 1.08, 6.84) and LC (OR = 3.22; 95% CI = 1.14, 9.09) groups versus usual care, but not for the EP group alone. In PAIRINGS at 3 months, intervention rates exceeded usual care (OR = 2.86; 95% CI = 1.21, 6.76); the number needed to treat to prevent 1 dyad from nonexclusive breastfeeding at 3 months was 10.3 (95% CI = 5.6, 50.7).

CONCLUSIONS

LCs integrated into routine care alone and combined with EP guidance from prenatal care providers increased breastfeeding intensity at 3 months postpartum.

Women's perceptions of breastfeeding barriers in early postpartum period: a qualitative analysis nested in two randomized controlled trials

OBJECTIVES

This study examined women's perceptions of early infant feeding experiences and identified early postpartum barriers to successful breastfeeding.

SUBJECTS AND METHODS

We conducted semistructured exit interviews at 6 months postpartum with a subsample of participants (n=67) enrolled in two randomized controlled trials of breastfeeding promotion. Study arms included (1) routine pre- and postnatal visits with an International Board Certified Lactation Consultant (IBCLC) (LC group), (2) electronically prompted guidance from prenatal care providers (EP group), (3) EP+LC combined, and (4) standard of care (control group). Interview transcripts were coded using grounded theory and analyzed in MAXqda. Code matrices were used to identify early postpartum breastfeeding barriers and were further examined in relation to treatment group using a mixed methods analysis.

RESULTS

The majority of the participants reported experiencing at least one barrier to breastfeeding. Barriers to breastfeeding were more commonly reported in the early postpartum than late postpartum period. The most common barrier during the early postpartum period was the perception of inadequate milk supply ("lactational") (n=18), followed by problems with latch, medical problems that were perceived as precluding breastfeeding, and medical staff and hospital practices. Participants frequently reported that the IBCLCs assisted them in anticipating, managing, and overcoming these barriers.

CONCLUSIONS

Our findings underscore the importance of integrating IBCLCs into routine pre- and postpartum care because they provide critical support that effectively addresses early postpartum barriers to breastfeeding.

Recruiting and retaining low-income, multi-ethnic women into randomized controlled trials: successful strategies and staffing

Developing effective recruitment and retention strategies in populations with traditionally high attrition rates is critical to the success of Randomized Controlled Trials (RCTs). Data on successful participation of women from low-income, minority populations in RCTs of behavioral interventions are limited. This is problematic given the multiplicity of Healthy People 2020 goals that target health disparities in these populations. This paper reports successful recruitment and retention methods from two separately funded NIH clinical trials of primary care-based prenatal interventions to increase breastfeeding among ethnically diverse, low-income women in urban medical centers in the Bronx, NY. It also presents the required staff effort necessary to conduct such a successful RCT, in terms of full-time equivalents (FTEs). Results include timely recruitment of 941 participants over 29 months, with 98.1% completing >¯¯1 follow-up interview. A recruitment and retention plan that maximized study staff access and availability to the participant, as well as strong study staff rapport with participants, addressed previously reported barriers in this population, optimizing follow-up rates. A qualitative assessment of the participants' study experience suggesting that high retention was due to strong rapport with participants, short interviews requiring little time commitment, and participants' perception of the study as informative, provides further evidence of our approach's effectiveness. Logistical protocol procedures and staff management strategies relating to successful recruitment/retention are provided to propose a practical, cost-effective and translational recruitment-retention plan for other researchers to adopt.
