what it measures: This indicator measures the proportion of people living with HIV who screen positive for TB symptoms who receive a recommended test for diagnosis of TB. * - rationale: • People living with HIV should be screened for TB symptoms and, if found positive, be tested for TB. | • WHO recommends rapid-diagnostic molecular tests, for example, Xpert MTB/RIF, as the first test for diagnosis of TB among people living with HIV. * - method: For the numerator and denominator: Programme records (for example, laboratory register for smear microscopy and Xpert MTB/RIF, ART registers) * * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm */ library HIVIND46Logic // Included Libraries using FHIR version '4.0.1' include HIVCommon version '0.0.1' called HIC include FHIRHelpers version '4.0.1' include WHOCommon called WCom include HIVElements called HE include HIVIndicatorElements called HIE // Indicator Definition parameter "Measurement Period" Interval<Date> default Interval[@2023-01-01, @2023-01-30] context Patient /* Populations */ /* *Initial Population */ define "Initial Population": true /** * Numerator * * Definition: Number of people living with HIV and having TB symptoms who were tested using a rapid molecular test (for example, Xpert MTB/RIF) as a first test during the reporting period * Calculation: COUNT of clients with "HIV status"='HIV-positive' AND "TB screening date" in the reporting period AND "TB screening result"='Screen positive for TB' AND "TB diagnostic test category"='mWRD test for TB' */ define "Numerator": HIE."Has HIV-positive Status" and //I related the two because otherwise a positive observation could come from another test type and be counted. exists( HE."mWRD test for TB" P with HE."Screen positive for TB" O such that P.partOf.references(O) where P.performed.toInterval() during "Measurement Period" ) /** * Denominator * * Definition: Number of people living with HIV who are screened for TB and found to have symptoms during the reporting period * Calculation: COUNT of clients with "HIV status"='HIV-positive' AND "TB screening date" in the reporting period AND "TB screening result"='Screen positive for TB' */ define "Denominator": HIE."Has HIV-positive Status" and exists( HE."TB diagnostic test category" P with HE."Screen positive for TB" O such that P.partOf.references(O) where P.performed.toInterval() during "Measurement Period" ) /* end Populations */ /* * Disaggregators */ define "Administrative Gender Stratifier": HIE."By Administrative Gender Stratifier" define "Age Stratifier": HIE."By Age Stratifier" define "Geographic Region Stratifier": HIE."By Geographic Region Stratifier" define "patientGroups Stratifier": HIE."patientGroups" define "pregnancy stratifier": HIE."pregnancy stratifier" define "Stratification": HIE."By Administrative Gender Stratifier".code + ':' + HIE."By Age Stratifier" + ':' + HIE."By Geographic Region Stratifier" + Combine(HIE.patientGroups, ':') + HIE."pregnancy stratifier".code Content: application/elm+xml Encoded data (52364 characters) Content: application/elm+json Encoded data (88572 characters)
