Research Questions Implementing integrated community case management training & QI support to CHWs: Is it feasible? Does it lead to gains in CHW knowledge, self- efficacy and practice? What is the effect on infant feeding practices, and uptake of PMTCT and MCH services?
Setting and Design 3 Setting: Ugu District, KwaZulu Natal, South Africa Design: Cluster randomized controlled trial CHW supervisors (N=30), CHWs (N=120) Mothers: ~8 mothers per CHW pre & post intervention
Participants and Timelines CHW: > 18 years old Grade 9 education or greater Employed by Department of Health to provide home support to pregnant women, mothers and children in Ugu District, SA Mothers > 18 years old Delivered live-born infant in past 12 months Reside in household assigned to participating CHW Baseline 6 Months12 Months CHW: Mothers: Pre- Intervention Post- Intervention
Analytic Approach Mixed-effects models Interaction of treatment group with visit month tested for differences in rate of change between groups

Self Efficacy Significantly improved self efficacy at 6 and 12 months (intervention vs control CHWs): Talking to a pregnant woman about HIV Advising a pregnant woman about her own nutrition Assisting a mother with breastfeeding Explaining services available for PMTCT Doing a postnatal visit to check the mother’s health & newborn baby Recognizing danger signs in pregnancy, newborn or postpartum mother

Receipt of ANC, PNC, HIV and PMTCT services (post-intervention)
Summary Compared to CHWs in control arm, CHWs in intervention arm: Significantly greater level of self-efficacy Significantly greater level of HIV and MCH-related knowledge Knowledge regarding HIV/MCH content sustained over time Compared to mothers in control catchment, mothers in intervention arm: Reported more frequent CHW visits and discussion about HIV/MCHN Significant improvement in exclusive breastfeeding in first 6 weeks Significant improvement in care-seeking for mothers and infants No change in receipt of HIV testing or receipt of PMTCT services – but prevalence overall was very high
Conclusions Training approach and materials were effective in knowledge transfer and highly appreciated even though demanding; QI supervision and support of CHWs was feasible and valued; Improved CHW knowledge, self-efficacy and practices were sustained over time; Some maternal behavior change observed, despite short period of intervention
