Geneva: World Health Organization; 2022 * * Data Concepts: * HIV.B.DE115: HIV status | HIV status reported after applying the national HIV testing algorithm. No single HIV test can provide an HIV-positive diagnosis. * HIV.B.DE116: HIV-positive | Client is HIV-positive * HIV.B.DE117: HIV-negative | Client is HIV-negative * HIV.B.DE118: Unknown | Client has unknown HIV status * HIV.D.DE75: Current ART regimen | The current ART regimen the client is taking * HIV.E.DE46: Delivery date | Date on which the woman delivered * HIV.E.DE67: Place of delivery | The type of place where the woman delivered * HIV.E.DE68: Health facility | The woman delivered at a health facility * HIV.E.DE69: Home | The woman delivered at home * HIV.E.DE70: Other | The woman delivered at another location that is not at home or at a health facility * HIV.E.DE87: Infant date of birth | The infant's date of birth (DOB) if known * HIV.E.DE112: HIV-exposed infant or child | Whether the infant or child was determined to have had HIV exposure * HIV.E.DE229: Infant ART start date | The date on which the infant was started or restarted on antiretroviral therapy (ART) * HIV.SRV.DE20: HIV-exposed infant or child | Whether the infant or child was determined to have had HIV exposure * * Additional Context * - what it measures: This indicator measures the delivery of prevention services to HIV-exposed infants immediately after birth. * - rationale: • ARV prophylaxis for HIV-exposed infants is critical for reducing the risk of mother-to-child transmission in the immediate postpartum period – part of Prong 3 of the PMTCT strategy. | • In particular, coverage of HIV-exposed infants who are born in facilities should be very high. | • When using the programme-based/service delivery denominator, the indicator measures coverage among only HIV-exposed infants who are born in facilities, which is a direct measure of a programme's ability to meet standards of care. * - method: For the numerator: Programme records (for example, PMTCT registers) | a) For the programme-based/service delivery denominator: Programme records, labour and delivery registers | b) For the population-based denominator: Modelling-based estimates (for example, Spectrum AIM). | | Note: The population-based denominator is a proxy measure for the number of infants born to HIV-infected women. | | The recommended reporting period is 12 months. * * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm * * Profiles: * - HivInfant * - HivMother * - HivChildDelivery * - HivAntiRetroviralTreatment * - HivStatus * - HivOnArt * */ library HIVIND39Logic // 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 HIV-exposed infants born within the past 12 months who were started on ARV prophylaxis at birth * Calculation: COUNT of infants who are an "HIV-exposed infant or child" AND "Infant date of birth" within reporting period AND "Infant ART start date" is on"Infant date of birth" */ define "Numerator": HIE."is HIV-exposed infant or child E.DE112" and exists(HE."ART start date" d where date from d same day as Patient.birthDate) /** * Denominator * * Definition: a) Programme-based/service delivery denominator: Number of HIV-positive women who delivered in a facility within the past 12 months. | | B) Population-based denominator: Number of HIV-positive women who delivered within the past 12 months. * Calculation: Programme-based/service delivery denominator: | COUNT of women with "HIV status"='HIV-positive' AND "Place of delivery" is a 'Health facility' AND "Delivery date" within reporting period | | Population-based denominator: | *Estimated number of HIV-positive women who delivered during the past 12 months */ define "Denominator": HIE."Has HIV-positive Status" and HIE."Has Delivery in Health Facility" /* end Populations */ /* * Disaggregators */ define "Geographic Region Stratifier": HIE."By Geographic Region Stratifier" define "Current ART regimen": HIE."Current ART regimen" define "Stratification": HIE."By Geographic Region Stratifier" + HIE."Current ART regimen".code Content: application/elm+xml Encoded data (28216 characters) Content: application/elm+json Encoded data (43920 characters)
