Abstract Number: TUPDE0204

BACKGROUND

• Treatment-eligible HIV-positive pregnant women have the highest risk of vertical transmission

• In 2010, 11% of 41,042 HIV-positive pregnant women initiated on ART in ANC.

• Low proportion was partially due to limited access to CD4 testing

• CD4 machines in Zimbabwe were mainly laboratory based and highly centralized

Use of CD4 POC technology in Zimbabwe

• To increase access to ART eligibility:

• In 2009, Pima TM point-of-care evaluated and endorsed in Zimbabwe

• portable, battery poweredproduce a CD4 count in 20mincan be used by non- lab staff

• EGPAF supported bypartners to procure50 POC CD 4 machines

Background

• Handover of the 50 POC CD4 machines

Background: TrainingsHealth worker trainings on use of POC CD4 machine and data collection tools

METHODS

A quasi-experimental before-and-after study was conducted, at 43 high-volume PMTCT sites

Deployment of the POC CD4 machines was the intervention

Data were collected before (Oct 2010 -June 2011) and after (Jul 2011- Mar 2012)

Data were analyzed using SPSS v15.0.

Statistical differences were tested

CD4 <350cells/mm3 2016 (48%) 738 (40%) 311 (43%)

• ART-eligible initiated on ART in ANC – 1289 (64%)

Conclusion Deployment of POC CD4 analyzers was

associated with significant increases in CD4 testing and ART initiation among HIV-positive pregnant women at the 43 intervention sites.

Based on these early findings, expansion of POC CD4 machines to all high-volume PMTCT sites in Zimbabwe is recommended to increase access to ART for eligible pregnant women towards elimination of new HIV infections in children by 2015.
