Table 3 WHO definitions of access, coverage and linkage to care [16]

Access: “Access is a broad term with varied dimensions: the comprehensive measurement of access requires a systematic assessment of the physical, economic, and socio-psychological aspects of people’s ability to make use of health services.”

Coverage: “Coverage of interventions is defined as the proportion of people who receive a specific intervention or service among those who need it.”

Linkage to care: e.g. proportion of infected people treated or referred for treatment, results reporting to patient, etc.
