A mobile health-facilitated behavioural intervention for community health workers improves exclusive breastfeeding and early infant HIV diagnosis in India: a cluster randomized trial.

The COMBIND intervention was easily integrated into India's existing PMTCT programme and improved early uptake of two PMTCT components that require self-motivated health-seeking behaviour, thus providing preliminary evidence to support COMBIND as a potentially scalable PMTCT strategy. Further study would identify modifications needed to optimize other PMTCT outcomes.
