 * Short Name: Repeat diagnosis of STI syndrome, HIV-positive clients
 *
 * Definition: % of people living with HIV diagnosed with a particular STI syndrome who were diagnosed with the same STI syndrome two or more times during the reporting period
 *
 * Numerator: Number of people living with HIV diagnosed with a particular STI syndrome two or more times during the reporting period
 * Numerator Calculation: COUNT of clients with "HIV status"='HIV-positive' AND with "Any STI syndrome diagnosed"=True on multiple values of "Visit date" in reporting period
 * Numerator Exclusions: 
 *
 * Denominator: Number of people living with HIV diagnosed with a particular STI syndrome during the reporting period
 * Denominator Calculation: COUNT of clients with "HIV status"='HIV-positive' with a "Visit date" in reporting period
 * Denominator Exclusions:

 * Disaggregations:
 * • Gender (female, male, other*)

 *  • STI syndrome (urethral discharge syndrome, vaginal discharge syndrome, lower abdominal pain, genital ulcer disease syndrome, or anorectal discharge) 
 *  • Cities and other administrative regions of epidemiologic importance
 *
 * Disaggregation Elements: Gender | Age | Key population member type | Syndrome/STI diagnosed

 *
 * Additional Context
 * - what it measures: A: % of people attending HIV prevention services who were diagnosed with the same STI | syndrome two or more times during the reporting period | B: % of people living with HIV who were diagnosed with the same STI syndrome two or more times during the reporting period
 * - rationale: Presenting with the same STI syndrome two or more times in a short period suggests that an individual was not treated appropriately, has an untreated partner or is practicing unsafe sex.
 * - method: Individual-level data obtained from programme records
 * 
 * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm
