The HIV continuum of care in the Bahamas in 2014 / El proceso continuo de atención de la infección por el VIH en las Bahamas en el 2014

ABSTRACT

Objective. The HIV cascade of care describes the spectrum of engagement in HIV care from diagnosis to viral suppression (VS). The study objective was to develop a baseline HIV cascade of care for new HIV diagnoses in the Bahamas in 2014. Methods. Individuals who were newly diagnosed with HIV in 2014 and known to be alive within a year of that diagnosis were included in the cascade of care (n = 250). Individuals with one CD4 or HIV viral load (VL) measure in 2014 were considered linked to care. Those with at least two CD4 counts in the year were considered retained in care. Eligibility for antiretroviral therapy (ART) was based on having a CD4 count < 350 cells/mm3. ART adherence was defined as filled prescriptions > 11 months/year. VL < 1 000 copies/ml was considered suppressed. Comparisons were made in the cascades by gender and age. Results. Of the 250 persons in the study, 79 of them (32%) were retained in care. Antiretrovirals (ARVs) were prescribed to 116 of the 250 (46%); of those 116, 48 of them (41%) achieved VS. A higher proportion of women achieved VS than did men, but this difference did not reach statistical significance. Similarly, there were differences in VS based on age, but the differences were not statistically significant. Conclusions. In the Bahamas, increased efforts are needed to help people living with HIV to link to and be retained in care. VS may remain suboptimal unless ART is scaled up and adherence interventions are included in measures to improve the treatment cascade.
