The SAM is designed to support decision making by providing national and district planners with the skills and tools to routinely map services and resource availability. Designed as a district-owned system, SAM can be implemented as a standalone system or integrated into the routine health information system as a supervisory tool. As a monitoring tool, SAM is recommended every six months to one year. The frequency of implementation may be adjusted to suit program needs when utilized as a periodic evaluation tool. The Facility SAM covers availability of the health equipment, staffing, drugs and commodities, and the services offered. The District SAM covers health infrastructure, human resources, and services available in the district.
