Background There is a lack of up-to-date real-life evidence on antiretroviral therapy (ART) strategies among people living with HIV (PLWH) in Portugal. This study aimed to describe the treatment strategy used in PLWH either initiating or switching ART. Methods Non-interventional, cross-sectional, multicenter study carried out between December 2019 and October 2021 in Portugal. Results A total of 237 PLWH were included in this study, 171 of whom were ART-experienced and 66 were ART-naïve. The study showed that triple regimens were the most common ART strategy and integrase strand transfer inhibitors-based therapy was the most frequently used therapeutic class in both ART-naïve and ART-experienced PLWH. Nevertheless, about a third of PLWH who started a triple regimen transitioned to a dual regimen. Patient-reported outcomes revealed high HIV literacy and similar ART preferences in both groups. Conclusions This real-world study showed that triple regimens were the most widely used ART strategy, even after the European AIDS Clinical Society guidelines introduced the recommendation of a dual regimen for naïve patients. The cohorts of this study presented a high level of HIV literacy at the time of inclusion. Our findings highlighted that taking pills only once a day is considered a very important feature for most patients.
