Capacity strengthening is premised on the six health systems strengthening building blocks with the aim of bridging the gap between supply and demand for quality integrated MNCAH, paediatric and adolescent HIV services. Priority areas include strengthening human resources for health, improving efficiency and effectiveness in service delivery, strategic information and knowledge management, and implementation research. Training is conducted at national and regional levels, using different approaches ranging from short to long-term training courses, mentorship and technical support, exposure through workshops and study visits, and supportive supervisory visits. Quality Improvement approaches are at the core of all capacity strengthening activities.
