Encounter is an interaction between a patient and healthcare provider(s) to provide healthcare service(s) or assess a patient's health status. There are many types of encounters (such as ambulatory inpatient home visits emergency and the like) which is the reason why the resource encompasses the lifecycle from pre-admission to the actual encounter (for ambulatory encounters) and admission stay and discharge (for inpatient encounters). Encounter is primarily used to record information about the actual activities that occurred where Appointment is used to record planned activities.

Observation represents one of the most important and central units of healthcare data exchange - different kinds of observations varying from clinical findings and measurements to social history. The resource is designed to cover a wide variety of use cases and as a result at its simplest a resource instance can consist of only a code value and status flag. The granularity of instance highly depends on the use case therefore the minimal viable data considered is a decision that needs to be made during profiling process.

HealthcareService resource describes the details of a single healthcare service or category of services that are provided by an organization at a location. The location of the services could be virtual as with telemedicine services.
