Point-of-care (POC) CD4 testing was implemented at a stand-alone HIV voluntary testing and counseling centre in Harare, Zimbabwe. To validate the use of this new technology, paired blood samples were collected from 165 patients either by a nurse or a laboratory technician and tested using POC and conventional laboratory CD4 machines. Finger prick (capillary) blood was collected directly into the PIMA POC CD4 Analyzer cartridges and tested immediately, whereas venous blood collected into evacuated tubes was used for CD4 enumeration on a Becton Dickinson FACSCalibur. There was no significant difference in mean absolute CD4 counts between the POC PIMA and Becton Dickinson FACSCalibur platforms (+7.6 cells/microL; P = 0.72). Additionally, there was no significant difference in CD4 counts between the platforms when run by either a nurse (+18.0 cells/microL; P = 0.49), or a laboratory technicians (-3.1 cells/microL; P = 0.93). This study demonstrates that POC CD4 testing can be conducted in a voluntary testing and counseling setting for staging HIV-positive clients. Both nurses and laboratory technicians performed the test accurately, thereby increasing the human resources available for POC CD4 testing. By producing same-day results, POC CD4 facilitates immediate decision-making, patient management and referral and may help improve patient care and retention. POC CD4 may also alleviate testing burdens at traditional central CD4 laboratories, hence improving test access in both rural and urban environments.

Background:Age-disaggregated analyses of prevention of mother-to-child transmission (PMTCT) program data to assess the uptake of HIV services by pregnant adolescent women are limited but are critical to understanding the unique needs of this vulnerable high-risk population.Methods:We conducted a retrospective analysis of patient-level PMTCT data collected from 2011 to 2013 in 36 health facilities in 5 districts of Zimbabwe using an electronic database. We compared uptake proportions for PMTCT services between adolescent (≤19 years) and adult (>19 years) women. Multivariable binomial regression analysis was used to estimate the association of the women's age group with each PMTCT service indicator.Results:The study analyzed data from 22,215 women aged 12–50 years (22.5% adolescents). Adolescents were more likely to present to antenatal care (ANC) before 14 weeks of gestational age compared with older women [adjusted relative risk (aRR) = 1.34; 95% confidence interval: 1.22 to 1.47] with equally low rates of completion of 4 ANC visits. Adolescents were less likely to present with known HIV status (aRR = 0.34; 95% confidence interval: 0.29 to 0.41) but equally likely to be HIV tested in ANC. HIV prevalence was 5.5% in adolescents vs 20.1% in adults. While >84% of both HIV-positive groups received antiretroviral drugs for PMTCT, 44% of eligible adolescents were initiated on antiretroviral therapy vs 51.3% of eligible adults, though not statistically significant.Conclusions:Pregnant adolescents must be a priority for primary HIV prevention services and expanded HIV treatment services among pregnant women to achieve an AIDS-free generation in Zimbabwe and similar high HIV burden countries.
