* Library: HIV.IND.14 Logic
* Ref No: PRV.14
* Short Name: OAMT minimum dose
*
* Definition: % of OAMT recipients receiving a maintenance dose greater than or equal to the recommended minimum dose
*
* Numerator: Number of people, at a specified date, maintained on methadone or buprenorphine receiving recommended minimum maintenance dose (WHO guidance recommends doses of ≥60 mg of methadone or ≥8 mg of buprenorphine*)
* Numerator Calculation: COUNT of clients with ("Medications prescribed"='Methadone' AND "Dose of medications prescribed" GREATER THAN OR EQUAL TO 60mg) OR ("Medications prescribed"='Buprenorphine' AND "Dose of medications prescribed" GREATER THAN OR EQUAL TO 8mg) for a specified "Reporting date"
* Numerator Exclusions: "Client being inducted on OAMT" OR "Client on reducing doses of OAMT"
*
* Denominator: Number of people receiving maintenance dose of methadone or buprenorphine at a specified date, excluding: a) individuals currently being inducted on OAMT and yet to reach the maintenance dose and b) individuals on reducing doses of OAMT.
* Denominator Calculation: COUNT of clients with "Medications prescribed" IN 'Methadone', 'Buprenorphine' for a specified "Reporting date"
* Denominator Exclusions: "Client being inducted on OAMT" OR "Client on reducing doses of OAMT"
*
* Disaggregations:
* • Gender (female, male, other**)
* • Age (15–19, 20–24, 25–49, 50+ years)
* • Provider type (key population-led or community-led organization, public sector provider, other entities such as private for-profit and not-for-profit organizations, including faith-based, international, nongovernmental)
* • Setting: facility-based service (including hospitals, health clinics, general practice offices, etc.) or community-based service (including drop-in centres, community service delivery points, mobile clinics or vans, outreach teams, community support groups, etc.)
* • Cities and other administrative regions of epidemiologic importance
*
* Disaggregation Elements: Gender | Age
*
* Numerator and Denominator Elements:
* Dose of medications prescribed
* Medications prescribed
* Reporting date

*
* 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.C.DE75: Medications prescribed | Medications the client was prescribed
* HIV.C.DE76: PrEP for HIV prevention | Client was prescribed pre-exposure prophylaxis (PrEP) for HIV prevention
* HIV.C.DE77: PEP for HIV prevention | Client was prescribed post-exposure prophylaxis (PEP) for HIV prevention
* HIV.C.DE78: Other | Client was prescribed other medications
* HIV.D.DE457: Medications prescribed | Name or regimen code of all other medications prescribed during the visit
* HIV.D.DE459: Dose of medications prescribed | Number of doses (quantity taken at a single point in time) of drugs prescribed/dispensed
* HIV.Config.DE22: Reporting date | Reporting date, for surveys performed on a specific date
*
* Additional Context
* - what it measures: Measures the proportion of OAMT recipients receiving the recommended minimum maintenance dose.
* - rationale: Evidence demonstrates that maximum benefit from OAMT is gained when individuals receive at least the recommended minimum maintenance dose.
* - method: Individual-level data obtained from programme records
*
* Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm
