CTAC Data Sets Natural history cohort Hospital-based ART trials Community-based ART programmes Web-based ART Register

Natural History Cohort Epi-info based –Flow charts of 2088 outpatients –Laboratory, clinical data, OI prophylaxis Pros –Doctors like flow charts of CD4 & WHO stages but not perceived non-useful data! Cons –Data transfer, LTFU, missed hospitalisations & deaths required other data sources Outputs –OI frequency, Kaplan-Meier survival

CTAC: Incidence Rates of Opportunistic Infections CTAC 2002 CD4+ T-cells/mm 3

Hospital-based ART Trials Excel spread sheet of CRF data –Lab, clinical events, hospitalisations, deaths Pros: –Trial data good quality, variable CD4 entry criteria, frequent visit intervals Cons: –Extracting data laborious Outputs: –Changed disease progression –Resource utilisation

Usapho Lwethu Community ART Data sources and follow up Patient live in recruitment area & must have attended local HIV clinic for > 6 months Household support by “Sizophila monitor” Schedule 1 NNRTI, schedule 2 PI/r Single referral hospital Post mortem is requested on all deaths Access to national mortality data base via “ID number”

Community ART Programme Sequel database, data capture sheets –Laboratory, clinical, QOL, adherence data Pros –Fixed visit schedule, LTFU rate low but deaths high, data captured on “lap-top” Cons –Needs data administrator, active search for missing data Outputs –Programme status reports of CD4, VL, survival etc

Pilot National ART Register Web-based minimum data from ART programme linked to drug supply –ID number –Clinical stage –Current drug prescriptions Linked to laboratory & pharmacy data –CD4 & Viral load monitoring –Drug monitoring

Proposed Register Outputs Patient retention, number on Rx, LTFU and discontinuing Drug switching patterns Time to first failure (MTCT exposure?) Survival (benefit if compare with natural history model!) Drug accountability, dispensing to patients & “leakage” Laboratory outcomes CD4/viral suppression at time-points, resistance
