A mobile HIV counseling and testing (HCT) program around Johannesburg piloted the integration of point-of-care CD4 testing, using the Pima™ Analyzer, to improve linkages to HIV care. We report results from this pilot program for patients testing positive (n=508) from May–October 2010. We analyzed three primary outcomes: assignment to testing group (offered POC CD4 or not; successful follow up (by phone); and completed the referral visit for HIV care within 8 weeks after HIV testing if successfully followed up. Proportions for each outcome were calculated and relative risks estimated using a modified Poisson approach. 311 patients were offered the POC CD4 test, and 197 patients were not offered the test. No differences in patient characteristics were observed between the two groups. Approximately 62.7% of patients were successfully followed up 8 weeks after HIV testing, with no differences observed between testing groups. Among those followed up, 54.4% reported completing their referral visit. Patients offered the POC CD4 test were more likely to complete the referral visit for further HIV care (RR 1.25, 95% CI: 1.00–1.57). In this mobile HCT setting, patients offered POC CD4 testing as part of the HCT services were more likely to visit a referral clinic after testing, suggesting rapid CD4 testing technology may improve linkage to HIV care. Future research can evaluate options for adjusting HCT services if POC CD4 testing were included permanently, as well as the cost-effectiveness of the POC CD4 testing compared to other approaches for improving linkage of care.
