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.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.DE161: HBsAg test date | Date client was tested for hepatitis B virus (HBV) * HIV.D.DE162: HBsAg test result | Hepatitis B virus test result (HBsAg) * HIV.D.DE163: Positive | HBsAg test result was positive * HIV.D.DE164: Negative | HBsAg test result was negative * HIV.D.DE165: Indeterminate | HBsAg test result was indeterminate * 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.G.DE17: HBsAg test date | Date client was tested for hepatitis B virus (HBV) * HIV.G.DE18: HBsAg test result | Hepatitis B virus test result (HBsAg) * HIV.G.DE19: Positive | HBsAg test result was positive * HIV.G.DE20: Negative | HBsAg test result was negative * HIV.G.DE21: Indeterminate | HBsAg test result was indeterminate * HIV.PRV.DE10: Date accessed HIV prevention intervention | Date the client accessed HIV prevention intervention * * Additional Context * - what it measures: A: % of people attending HIV prevention services who were tested for HBsAg and had a positive HBsAg test result during the reporting period (laboratory-based test or rapid test) | B: % of people living with HIV who were tested for HBsAg and had a positive HBsAg test result during the reporting period (laboratory-based test or rapid test) | C: % of pregnant women who were tested for HBsAg and had a positive HBsAg test result during the reporting period (laboratory-based test or rapid test) * - rationale: • Testing for HBV identifies HIV and HBV co-infection so that HIV treatment regimens can be adjusted to treat chronic hepatitis B infection as well. | • The HBsAg positivity rate in ANC attendees can be used to monitor the prevalence of HBV in the population and give an indication of the HBV burden. * - method: Patient monitoring tools (electronic or paper), for example, hepatitis and HIV testing service records, lab registers, logbooks and reporting forms at facility and community levels, EMR/electronic information systems * * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm * * Profiles: * -
