MOMENTUM Country and Global Leadership collaborated with the Sierra Leone Ministry of Health to develop a national “Investment Case for Sierra Leone’s Community Health Worker Policy.” The Investment Case provides the Government of Sierra Leone and development partners with clear financing requirements and impact projection justifying continued investments to ensure institutionalization of sustainable, accessible, and equitable community health services at scale. Using the Community Health Planning and Costing Tool (CHPCT 2.0), the Community Health Worker Coverage and Capacity (C3) Tool, and the Lives Saved Tool (LiST), this investment case analyzes the costs and benefits of the CHW program from 2021 to 2026.
