Modes or channels of health service delivery. Examples include public and private health facilities (for example, health posts, clinics, health centres, mobile clinics, emergency care units, district hospitals, and pharmacies), other entities (for example, home-based care, schools, community centres, long-term care facilities) and outreach services, campaigns or digital platforms. These can be classified in a variety of ways. Examples are familyoriented community-based services; population-oriented schedulable services; and individualoriented clinical services at different levels (primary level, first referral level and second referral level).
