HIV treatment cascade in regions of Peru with the highest HIV prevalence

Abstract

Objectives: To describe the HIV treatment cascade and care continuum in regions of highest HIV prevalence in Peru.

Methods: An observational longitudinal study was carried out in 14 tertiary hospitals in Peru. These are the main hospitals that administer antiretroviral treatment (ART) in the regions that represent approximately 95% of reports of HIV/AIDS cases in Peru in 2013. We included individuals older than 18 years newly diagnosed with HIV from 1 January 2011 to 31 December 2012. Medical records were reviewed until 2015.

Results: A total of 2119 people living with HIV (PLHIV) were identified in the selected health facilities (mean age = 35.26 years, 78% male). 97.25% [1845/1897; 95% confidence interval (CI): 96.4-97.9%] of the patients attended the consultation at least once during the follow-up, but only 64.84% (885/1365; 95% CI: 62.2-67.4%) attended within a month after the diagnosis. After starting ART, 74.63% (95% CI: 71.9-77.2%) of PLHIV remained in healthcare. Regardless of the time after diagnosis, 88.40% (1837/2078; 95% CI: 86.9-89.7%) of PLHIV started ART during the observation time. However, 78.68% (95% CI: 76.8-80.4%) did so during the first post-treatment year and only 28.88% (95% CI: 27.9-31.9%) after 1 month. After starting treatment, it was observed that 51.60% (95% CI: 49.2-54%) of PLHIV reached viral suppression during the follow-up period.

Conclusions: Further analysis and improvements in the definition of indicators are required to achieve conclusive results; however, these data will give us a general understanding of the progress of Peruvian health policies in achieving the goal established by the WHO.
