“Taking care of your pregnancy”: a mixed-methods study of group antenatal care in Kakamega County, Kenya

BACKGROUND: Traditional antenatal care (ANC) models often do not meet women’s needs for information, counseling, and support, resulting in gaps in quality and coverage. Group ANC (GANC) provides an alternative, person-centered approach where pregnant women of similar gestational age meet with the same health provider for facilitated discussion. F studies show associations between GANC and various outcomes. METHODS: We employed a pre-post quasi-experimental design using mixed methods to assess a GANC model (Lea Mimba Pregnancy Clubs) at six health facilities in Kakamega County, Kenya. Between April 2018 and January 2019, we tracked 1652 women assigned to 162 GANC cohorts. Using an intention-to-treat approach, we conducted baseline (N = 112) and endline surveys (N = 360) with women attending immunization visits to assess outcomes including experience of care, empowerment and self-efficacy, knowledge of healthy practices and danger signs, and practice of healthy behaviors, including ANC retention. At endline, we conducted 29 in-depth interviews (IDIs) and three focus group discussions with women who were currently and previously participating in GANC, and 15 IDIs with stakeholders. RESULTS: The proportion of survey respondents with knowledge of three or more danger signs during pregnancy more than tripled, from 7.1% at baseline to 26.4% at endline (OR: 4.58; 95% CI: 2.26–10.61). We also found improvements in women’s reports about their experience of care between baseline and endline, particularly in their assessment of knowledge and competence of health workers (OR: 2.52 95% CI: 1.57–4.02), respect shown by ANC providers (OR: 1.82, 95% CI: 1.16–2.85), and women’s satisfaction with overall quality of care (OR: 1.62, 95% CI: 1.03–2.53). We saw an increase from 58.9% at baseline to 71.7% at endline of women who strongly agreed that they shared their feelings and experiences with other women (OR: 1.73, 95% CI: 1.1–2.7). The mean number of ANC visits increased by 0.89 visits (95% CI: 0.47–1.42) between baseline (4.21) and endline (5.08). No changes were seen in knowledge of positive behaviors, empowerment, self-efficacy, and several aspects related to women’s experience of care and adoption of healthy behavior constructs. Qualitatively, women and stakeholders noted improved interactions between health providers and women, improved counseling, increased feelings of empowerment to ask questions and speak freely and strengthened social networks and enhanced social cohesion among women. CONCLUSIONS: GANC offers promise for enhancing women’s experience of care by providing improved counseling and social support. Additional research is needed to develop and test measures for empowerment, self-efficacy, and experience of care, and to understand the pathways whereby GANC effects changes in specific outcomes.
