Multisectoral actions in primary health care: A realist synthesis of scoping review.

Multisectoral actions enable policy and actions of other sectors in health involving multiple stakeholders and processes. Multisectoral actions at the macro-level provide strategic policy directions; and operationalise non-health sector policies to mitigate their spillover effects on health at the meso-level. At micro-level, MSAs support service provision and utilisation, and lifestyle and behaviour modification of people leading to equity and universality of health outcomes. Proper functional institutional mechanisms are warranted at all levels of health systems to implement MSAs on health.
