Following the World Health Organization's guidelines for rapid antiretroviral therapy (ART) initiation [≤7 days after human immunodeficiency virus (HIV) diagnosis], China implemented Treat-All in 2016 and has made significant efforts to provide timely ART since 2017. This study included newly diagnosed HIV adults from Tianjin, China, between 2016 and 2022. Our primary outcome was loss to follow-up (LTFU) at 12 months after enrollment. The secondary outcome was 12-month virological failure. The association between rapid ART and LTFU, as well as virological failure, was assessed via Cox regression and logistic regression. A total of 896 (19.1%) of 4688 participants received ART ≤7 days postdiagnosis. The rate of rapid ART has increased from 7.5% in 2016 to 33.3% by 2022. The rapid ART group had an LTFU rate of 3.3%, as opposed to 5.0% in the delayed group. The rapid ART group had a much reduced virological failure rate (0.6% vs. 1.8%). Rapid ART individuals had a reduced likelihood of LTFU [adjusted hazard ratio: 0.65, 95% confidence intervals (CI): 0.44-0.96] and virological failure (adjusted odds ratio: 0.35, 95% CI: 0.12-0.80). The real-world data indicated that rapid ART is practicable and beneficial for Chinese people with HIV, providing evidence for its widespread implementation and scaling up.
