What is an encounter?
A patient visits a health center or hospital. For each electronic form completed for a patient, a new encounter is created. Each will have a unique encounter_id and encounter_type. Forms could be completed by different departments (ie. drug pickup, visit with an HIV clinician, Diabetes visit, food package received), and will have an associated encounter_type (ie. ART Drug Regimen Pickup, Adult intake, food assistance, lab test, etc). Each encounter has an encounter type, date/time, location and provider.
