* Short Name: TB diagnostic testing type
*
* Definition: % of people living with HIV with TB symptoms who receive a rapid molecular test, for example, Xpert MTB/RIF, as a first test for diagnosis of TB
*
* Numerator: 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
* Numerator 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'
* Numerator Exclusions:
*
* Denominator: Number of people living with HIV who are screened for TB and found to have symptoms during the reporting period
* Denominator 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'
* Denominator Exclusions:

* Disaggregations:
* • Gender (female, male, other*)
* • Age (0–4, 5–9, 10–14, 15–19, 20–24, 25–29, 30–34, 35–39, 40–44, 45–49, 50+ years)**
* • Key populations (men who have sex with men, people living in prisons and other closed settings, people who inject drugs, sex workers, trans and gender diverse people)***
* • Pregnant or breastfeeding women
* • Cities and other administrative regions of epidemiologic importance
*
* Disaggregation Elements: Gender | Age | Key population member type | Currently pregnant | Breastfeeding

*
* 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.DE29: Currently pregnant | Client is currently pregnant
* HIV.B.DE32: Breastfeeding | Infant is being breastfed by mother
* 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.DE31: Currently pregnant | Client is currently pregnant
* HIV.D.DE32: Breastfeeding | Client is giving infant breast milk
* HIV.D.DE986: TB screening result | Record the result of the tuberculosis (TB) screening
* HIV.D.DE987: Screen positive for TB | Screening result was positive for tuberculosis (TB)
* HIV.D.DE988: Screen negative for TB | Screening result was negative for tuberculosis (TB)
* HIV.D.DE989: Inconclusive | Screening result was inconclusive for tuberculosis (TB)
* HIV.D.DE990: TB screening date | Date the TB screening was conducted
* HIV.D.DE992: TB diagnostic test category | The type of diagnostic test performed to detect tuberculosis (TB) disease
* HIV.D.DE993: LF-LAM | Client tested for tuberculosis with a lateral flow urine lipoarabinomannan assay
* HIV.D.DE994: mWRD test for TB | Client tested with a WHO-recommended molecular diagnostic test to detect Mycobacterium tuberculosis (MTB)
* HIV.D.DE995: Microscopy - Sputum acid-fast bacilli (AFB) | Client tested for tuberculosis with a sputum acid-fast bacilli (AFB)
* HIV.D.DE996: TB Culture | Client tested for tuberculosis (TB) with a culture
* 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.SRV.DE7: Currently pregnant | Client is currently pregnant
*
* Additional Context
* - 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
