The URL of a measure for which the gaps in care report will be created. A measure URL is specified in the url element of the Measure resource. The measure URL remains the same when the measure is stored on different servers.

The start of the measurement a gaps through period. In keeping with the semantics of the date parameter used in the FHIR search operation, This may be the period will start at the beginning of the measurement period implied defined by the supplied timestamp. E.g. a value of 2014 would set the measure, or a customized desired performance period s start date determined by a payer, a provider, a measure program, and etc.

The end of the measurement period. The a gaps through period (the gaps through date). The gaps through date could be a past date or a future date. For example, today's date is 2020-06-18, 1) if periodEnd date is 2020-09-30, it returns gaps through 2020-09-30, and 2) if the periodEnd date is 2020-05-31, it returns gaps through 2020-05-31.

Subject(s) for which the care gaps report will end at be produced. The subject may be a Patient, Practitioner, PractitionerRole, Organization, Location, Device, or Group. Subjects provided in this parameter SHALL match the end subjectType of the period implied by measure being evaluated (e.g. if the supplied timestamp. E.g. Measure.group.subjectType is Patient, the subject SHALL be a value reference to a Patient or a Group of 2014 would set the period end Patients). If no subject is provided, what subjects are evaluated is up to the server. This parameter cannot be 2014-12-31T23:59:59 inclusive used with the subjectGroup parameter.

Subject for which the gaps in care report will be created is provided as a Group resource. Subjects provided in this parameter SHALL match the subjectType of the measure being evaluated. (e.g. if the Measure.group.subjectType is Patient, the subject SHALL be a reference to a Patient or a Group of Patients). If no subject is provided, what subjects are evaluated is up to the server. This parameter cannot be used with the subject parameter.

The topic to be used Reference to determine which measures are considered a Practitioner for which the care gaps report. Any measure with the given topic in care report will be included created. For a practitioner focused gaps in care report, this is a required In Parameter. The Server needs to make sure that practitioner is authorized to get the gaps in care report for and know what measures the practitioner are eligible or qualified.

Reference to an Organization for which the gaps in care report will be created. Either 'organization' or 'organizationResource' SHALL be provided, but not both.

Organization for which the gaps in care report will be created is provided as an Organization resource. This is intended to support the use case in which the organization information is not on the server performing the evaluation, for example an ad-hoc group of practitioners that are part of a provider group. Either 'organization' or 'organizationResource' SHALL be provided, but not both.

Subject The location(s) for which the care gaps in care report will be produced run. This parameter is reflected in the location element of the resulting MeasureReport(s).

Indicates status of a care gap. For all [open, closed, and prospective gaps], three seperate status parameters must be provided. For a positive proportion measure, gap means the patient is not in the numerator. For an inverse (negative) proportion measure (e.g., Diabetes: Hemoglobin A1c (HbA1c) Poor Control (> 9%)), gap means the patient is in the numerator.

The result isDocument parameter controls whether a Gaps in Care Composition is returned in the Bundle (i.e. if the Bundle is of type 'Document'). When 'true,' the care gaps report returned Bundles contain the Gaps in Care Composition. This parameter defaults to 'true.'

Any input parameters for the evaluation. Parameters defined in this input will be returned made available by name to the CQL expression. Parameter types are mapped to CQL as specified in the Using CQL with FHIR implementation guide. If a parameter appears more than once in the input Parameters resource, it is represented with a List in the input CQL. If a parameter has parts, it is represented as a Tuple in the input CQL.

Specifies an asset-collection library that provides dependency version resolution and expansion rules for the operation. See the version manifest discussion in the Canonical Resource Management Infrastructure IG for a complete description of how manifest values are used to provide defaults for dependency version resolution and expansion parameters. Parameters specified directly in the operation override behaviors specified by the manifest parameter. In general, if this parameter is supplied, it is expected to be used in nested operation calls. For example, in evaluating a measure, if the expansion of a value set is required, this parameter SHALL be supplied to that expansion.

The $care-gaps operation returns zero or more document bundle Bundles, one for each input subject. Consistent with FHIR Documents generally, each Bundle SHALL have a MeasureReport Composition as the first entry in the document Bundle, and that Composition SHALL be limited to a single subject. See the guidance on Bundle structure for each included measure discussion about the Bundle content and organization.\n\nNote that even though there is a single parameter named return of type Bundle, it is a multi-cardinality parameter, and so will still be returned using a Parameters resource, as described in the general operations framework response .
