      .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 when using this profile. It provides the floor for standards development for specific use cases.General structure for capturing comorbid conditions with respect to a primary ('index') condition. The user can use this profile in three ways: (1) free-form, listing any conditions they wish to highlight as significant comorbidities, (2) following a formal paradigm such as the Charlson Comorbidity Index or the NCI Comorbidity Index, or (3) use disease categories defined for registry reporting purposes, such as those defined by Center for International Blood and Marrow Transplant Research (CIBMTR).

One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.'
