Introduction
The World Health Organization advocates for increased accessibility
of HIV-related point-of-care (POC) diagnostics in settings that lack
laboratory infrastructure. The aim of this study is to assess the impact of
POC diagnostics on maternal health outcomes in HIV-infected women.
Methods
A systematic literature review used multiple data sources as follows:
Cochrane Infectious Disease Group Specialized Register; Cochrane Central
Register of Control Trials, published in The Cochrane Library; PubMed;
EBSCOhost and LILACS from January 2000 to October 2015. References of
included studies were hand searched. Randomized controlled trials (RCTs) and
observational studies examining health outcomes of HIV-infected women were
eligible for inclusion in this review. The Cochrane Risk of Bias tool was
used for bias assessment of the included studies. PRISMA guidelines were
used for reporting.
Results
Of the 695 studies identified, six retrievable studies (five
cross-sectional studies and one case control study) met the inclusion
criteria and were included in this study. These studies examined a total of
167 HIV-infected women in different study settings. No studies reported
evidence of CD4 count, viral load and TB, and the syphilis POC test impact
on HIV-infected women was not found by this study. Included studies reported
the impact of various HIV rapid tests across the following five maternal
outcomes: timely receipt of results with pooled effect size (ES) =
1.00 (95% confidence interval [CI]: (0.98; 1.02);
enabling partner testing, ES = 0.95 (0.85; 1.04); prevention of
mother-to-child transmission of HIV, ES = 0.86 (0.79; 0.93); linkage
to antiretroviral treatment (ART), ES = 0.76 (0.69; 0.84); and
linkage to HIV care, ES = 0.50 (0.18; 0.82). No studies reported
evidence of the impact of POC testing on maternal mortality or maternal and
child morbidity of HIV-infected women.
Conclusions
The review provides an international overview of the impact of HIV
POC diagnostics on maternal outcomes in HIV-infected women, showing the
evidence that the HIV POC test is significantly associated with decreased
mother-to-child transmission of HIV and increased linkage to ART and HIV
care for HIV-infected women. It also revealed a gap in the literature aimed
at assessing the impact of POC diagnostics on maternal morbidity and
mortality in HIV-infected women.
