 * Ref No: STI.3A
 * Short Name: Syphilis treatment coverage, HIV prevention services
 *
 * Definition: % of people attending HIV prevention services tested positive for syphilis who were treated based on national guidelines during the reporting period
 *
 * Numerator: Number of people attending HIV prevention services who tested positive for syphilis and were treated based on national guidelines during the reporting period
 * Numerator Calculation: COUNT of clients with "Syphilis test date" in the reporting period AND "Syphilis test result"='Positive' AND "Syphilis treatment start date" in the reporting period
 * Numerator Exclusions: 
 *
 * Denominator: Number of people attending HIV prevention services who tested positive for syphilis during the reporting period
 * Denominator Calculation: COUNT of clients with "Syphilis test date" on "Date accessed HIV prevention intervention" in the reporting period AND "Syphilis test result"='Positive'
 * Denominator Exclusions: 
 *
 * Disaggregations:
 * • Gender (female, male, other*) 
 *  • Age (15–19, 20–24, 25–29, 30–49, 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)** 
 *  • HIV status (HIV-positive, HIV-negative, unknown status) 
 *  • Cities and other administrative regions of epidemiologic importance
 *
 * Disaggregation Elements: Gender | Age | Key population member type | HIV status | HIV prevention intervention
 *
 * Numerator and Denominator Elements:
 * Date accessed HIV prevention intervention 
 *  Syphilis test date 
 *  Syphilis test result 
 *  Syphilis treatment start date

 * Additional Context
 * - what it measures: A: % of people attending HIV prevention services who tested positive for syphilis and | were treated based on national guidelines during the reporting period | B: % of people living with HIV who tested positive for syphilis and were treated based on national guidelines during the reporting period | C: % of pregnant women who tested positive for syphilis and were treated based on national guidelines during the reporting period
 * - rationale: Prompt treatment of individuals positive for syphilis is important for improving their health and reducing sexual and vertical transmission of syphilis.
 * - method: Individual-level data obtained from programme records.   |  | If individual-level data are not available, the indicator can be reported using aggregate programme data.
 * 
 * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm
