      .descriptionThe US Core Observation Screening Assessment Profile meets the requirements of the US Core Data for Interoperability (USCDI) Assessments. To promote interoperability and adoption through common implementation, it sets the minimum expectations for the Observation Resource to record, search, and fetch observations representing the questions and responses to surveys and screening and assessment tools. For example, a social history status such as education or food insecurity or an assessment of the patient's cognitive, functional, or disability status. It can represent a single response, multiple responses, and multi-select "check all that apply" type questions. It identifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases.The number of heart beats in a minute.

When there is a heirarchical grouping of questions, the observation "panels" can be nested. Because surveys, screenings, and assessments can be arbitrarily complex structurally, not all structures can be represented using this Observation grouping pattern.' vs 'When using this element, an observation will typically have either a value or a set of related resources, although both may be present in some cases.
