Geneva: World Health Organization; 2022 * * Data Concepts: * HIV.A.DE17: Age | Calculated age (number of years) of the client based on date of birth * HIV.A.DE18: Gender* | Gender of the client* * HIV.A.DE19: Female | Client identifies as female * HIV.A.DE20: Male | Client identifies as male * HIV.A.DE21: Transgender male | Client identifies as transgender male * HIV.A.DE22: Transgender female | Client identifies as transgender female * HIV.A.DE23: Other | Additional category * HIV.B.DE50: Key population member type* | The type of key population that the client is included in * HIV.B.DE51: Sex worker | Client is a sex worker * HIV.B.DE52: Men who have sex with men | Client is a man who has sex with men * HIV.B.DE53: Trans and gender-diverse people | Client identifies as trans and gender-diverse * HIV.B.DE54: People who inject drugs | Client is a person who injects drugs * HIV.B.DE55: People living in prisons and other closed settings | Client lives in a prison or another closed setting * HIV.B.DE72: ART start date | The date on which the client started or restarted antiretroviral therapy (ART) * 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.DE38: On ART | Client is currently taking ART * HIV.D.DE39: ART start date | The date on which the client started or restarted ART * HIV.E.DE114: Key population member type* | The type of key population that the infant's mother is included in * HIV.E.DE115: Sex worker | Infant's mother is a sex worker * HIV.E.DE116: People who inject drugs | Infant's mother is a person who injects drugs * HIV.E.DE117: Trans and gender-diverse people | Infant's mother identifies as trans and gender-diverse * HIV.E.DE118: People living in prisons and other closed setting | Infant's mother is in a prison or closed setting * HIV.H.DE47: On ART | Client is currently taking ART * HIV.SRV.DE6: ART start date | The date on which the client started or restarted antiretroviral therapy (ART) * HIV.Config.DE19: Other priority populations | Other populations of priority of HIV prevention and care in local context (provided during adaptation) * * Additional Context * - what it measures: This indicator measures the expansion of ART programmes. * - rationale: • Monitoring trends in new ART patients provides managers with important information for forecasting the need for ARV and allocation of staff to ensure quality of care for ART. | • Initiation of ART is one of the sentinel events for HIV surveillance. * - method: HIV patient monitoring tools (for example, patient records/EMRs, ART registers). | | The recommended reporting period is 12 months. * * Suggested Scoring Method: continuous-variable | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/cv-measure-cqfm */ library HIVIND30Logic // 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 define "Measure Population": HIE."Has HIV-positive Status" and (date from start of HE."First On ART".effective.toInterval() during "Measurement Period") /* * As defined by Member States */ define "Initial Population": true /* * NOTE: Modeled as a Continuous Variable measure because this is an estimated denominator proportion measure */ define function "Measure Observation"(Patient "Patient"): 1 /* * Disaggregators */ define "Administrative Gender Stratifier": HIE."By Administrative Gender Stratifier" define "Age Stratifier 2": HIE."By Age Stratifier 2" define "Geographic Region Stratifier": HIE."By Geographic Region Stratifier" define "patientGroups Stratifier": HIE."patientGroups" define "Stratification": HIE."By Administrative Gender Stratifier".code + ':' + HIE."By Age Stratifier 2" + ':' + HIE."By Geographic Region Stratifier" + Combine(HIE.patientGroups, ':') Content: application/elm+xml Encoded data (31436 characters) Content: application/elm+json Encoded data (51120 characters)
