Effect of trust in village health workers on the use of facility-based follow-up postnatal care services in two districts in the Lao People's Democratic Republic.

Background: Despite high coverage of antenatal care services (89.8%) and facility-based deliveries (79.8%), delayed initiation or lack of follow-up postnatal care (PNC) visits remains a challenge in the Lao People's Democratic Republic (Lao PDR). Follow-up PNC encourages healthy lifestyles and monitoring mothers' and newborns' health to decrease postpartum complications and hospital readmissions. While village health volunteers and workers (VHVs/VHWs) are essential for health promotion in Lao PDR, the extent to which mothers' trust in VHVs/VHWs helps promote better service utilization has not been studied.

Objectives: We investigated the trust levels in VHVs/VHWs among ethnic minority mothers and the influence on the use of facility-based follow-up PNC.

Methods: We utilized cross-sectional data from July and August 2024, collected as a baseline survey for a quasi-experimental study conducted in 35 villages across the Sepone and Vilabuly districts. We compared the respondents' PNC usage and characteristics using chi-square tests and Fisher's exact tests. Standard binary logistic regression analyses were conducted to estimate the effects of various factors on the utilization of facility-based follow-up PNC. Trust in VHVs/VHWs was a construct variable based on their provision of emotional support, relevant information, adequate discussion time, effective care, and the likelihood of future pregnancy-related care.

Results: The study enrolled 241 mothers (mean age 24 years, SD 5.7), including 110 from Sepone and 131 from Vilabuly. Overall, the follow-up PNC coverage rate was 19.0%, and there was no significant difference between Sepone and Vilabuly, despite variations in access to healthcare and engagement with VHVs/VHWs. High trust in VHVs/VHWs was linked to 12.25 times higher odds of utilizing follow-up PNC than low trust (95% CI 2.2-67.8). In addition, having an older child (9-12 months) and immediate PNC utilization were beneficial for subsequent PNC use. Unexpectedly, contact with VHVs/VHWs during prenatal and/or postnatal periods decreased the odds of utilizing follow-up PNC, with distance to health facilities and adherence to traditional gender norms also having a similar negative effect.

Conclusions: Facility-based follow-up postnatal care was critically low among respondents; however, increasing trust in VHVs/VHWs may foster improvements. Along with increasing contact frequency, offering quality support to mothers through VHVs/VHWs while emphasizing the complementary nature of community-based and facility-based care could be beneficial. Effective interventions may also include enhancing immediate PNC and tackling physical accessibility challenges, as well as restrictive gender norms through male involvement.
