It is important to report the testing (screening) algorithm generally used in the country. If both treponemal and nontreponemal test results on an individual person are available, then syphilis positivity should be defined as having positive results in both tests. Collecting information on the testing algorithm used to determine positivity is important so that prevalence estimates can be adjusted to look at trends.\n * \n * Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm\n */\n\nlibrary HIVIND62Logic\n\n// Included Libraries\nusing FHIR version '4.0.1'\n\ninclude HIVCommon version '0.0.1' called HIC\ninclude FHIRHelpers version '4.0.1'\n\ninclude WHOCommon called WCom\ninclude HIVElements called HE\ninclude HIVIndicatorElements called HIE\ninclude HIVConfig called Config\n\n// Indicator Definition\nparameter \"Measurement Period\" Interval<Date> default Interval[@2023-01-01, @2023-01-30]\n\ncontext Patient\n/* Populations */\n\n/*\n *Initial Population\n */\n\n\ndefine \"Initial Population\":\n true\n\n/**\n * Numerator\n * \n * Definition: Number of people attending HIV prevention services who tested positive for syphilis during the reporting period (tested positive on both nontreponemal and treponemal tests or tested positive on either nontreponemal or treponemal test) | \n * Calculation: COUNT of clients with \"Syphilis test date\" in the reporting period AND \"Syphilis test result\"='Positive'\n */\n\ndefine \"Numerator\":\n exists(HE.\"Positive B.DE251\" S\n with HE.\"Syphilis test date B.DE249\" P\n such that S.partOf.references(P) and P.performed.toInterval() during \"Measurement Period\")\n\n\n\n/**\n * Denominator\n *\n * Definition: Number of people attending HIV prevention services tested for syphilis | \n * Calculation: COUNT of clients with \"Syphilis test date\" on \"Date accessed HIV prevention intervention\" in the reporting period\n */\n\ndefine \"Denominator\":\n exists(HE.\"Syphilis test date B.DE249\" P\n where P.performed.toInterval() during \"Measurement Period\"\n and exists (HE.\"Date accessed HIV prevention intervention\" t where t = start of P.performed.toInterval()))\n \n\n/* end Populations */\n\n/*\n * Disaggregators\n */\n\ndefine \"Administrative Gender Stratifier\":\n HIE.\"By Administrative Gender Stratifier\"\n\ndefine \"Age Stratifier\":\n HIE.\"By Age Stratifier 9\"\n\ndefine \"Geographic Region Stratifier\":\n HIE.\"By Geographic Region Stratifier\"\n\ndefine \"patientGroups Stratifier\":\n HIE.\"patientGroups\"\n\ndefine \"HIV prevention intervention\":\n HIE.\"HIV prevention intervention\"\n\ndefine \"HIV Status\":\n HIE.\"HIV Status Stratifier\"\n\ndefine \"Stratification\":\n HIE.\"By Administrative Gender Stratifier\".code \n + ':' + HIE.\"By Age Stratifier 9\"\n+ ':' + HIE.\"By Geographic Region Stratifier\"\n+ Combine(HIE.patientGroups, ':')\n+ Combine(HIE.\"HIV prevention intervention\", ':')\n+ ':' + HIE.\"HIV Status Stratifier\".code
