ART data from the Department of Health (DoH) and Statistics South Africa (SSA) mid-year population estimates were used to approximate antiretroviral therapy (ART) need among adults in the CTMM, as previously published.
(3) Secondly, this approach assumes that the proportion of adults receiving ART in the CTMM is similar to that of the rest of the country; this is probably an underestimate, considering routine monitoring data from the FPD.1 Thirdly, the DoH data may not account for under- or over-reporting, including non-adherence, loss to follow-up, transfer and death.
Despite these limitations, the approach seemed reasonable and simple for approximating ART need (total and initiation) among adults in the CTMM. However, when compiling the 2011 FPD report, we observed the following in the 2010 and 2011 SSA midyear population estimates: the estimated number of adults receiving ART was similar between 2010 and 2011, (2,5) but estimated ART need decreased drastically in 2011, to lower than the number of adults receiving ART (Fig.
Since 2007, an annual survey has been carried out of organisations providing HIV/AIDS-related services in the City of Tshwane Metropolitan Municipality (CTMM) to collect information on service provision, and to estimate service needs.
The survey was conducted in the CTMM over 7 weeks in May-June 2010.
