1) Collect the required data by conducting key informant interviews (health facility staff, health authorities, people living near the health facilities, health facility users), review documents (showing when different people were treated) and spontaneous visits (in the late evening, early morning, weekend, public holiday).
2) To calculate the indicator's value, divide the number of health facilities operating non-stop by the total number of surveyed facilities. Multiply the result by 100 to convert it to a percentage.
