Strategies for implementing community-based primary health care (CBPHC) programs focus on community collaboration, intervention delivery, and health systems strengthening. Key strategies include forming community health worker programs and women's groups, conducting home visits and outreach, and strengthening drug supply and the referral system. Successful strategies in one program included active case finding, testing and treating malaria in homes, follow-up visits, connecting women to prenatal care, removing user fees, and having one community health worker per 2,800 people to facilitate rapid referrals, which helped contribute to a decline in under-5 mortality.
