Too Fast to Stay on Track? Shorter Time to First Anti-retroviral Regimen is Not Associated with Better Retention in Care in the French Dat'AIDS Cohort

Background: Rapid antiretroviral therapy (ART) initiation has been proven beneficial for patients and the community. We aimed to analyze recent changes in timing of ART initiation in France and consequences of early start.

Methods: We selected from a prospective nationwide cohort, on 12/31/2017, patients with HIV-1 infection diagnosed between 01/01/2010 and 12/31/2015. We described time from (1) diagnosis to first specialized medical encounter, (2) from this encounter to ART initiation, (3) from diagnosis to first undetectable HIV viral load (VL). We analyzed the determinants of measured temporal trends. A multivariate logistic regression was performed to assess characteristics related with 1-year retention in care.

Results: In the 7 245 included patients, median time (1) from HIV diagnosis to first medical encounter was 13 (IQR: 6-32) days, (2) to ART initiation was 27 (IQR: 9-91) days, decreasing from 42 (IQR: 13-272) days in 2010 to 18 (IQR: 7-42) in 2015 (p<0.0001), (3) to first undetectable VL was 257 (IQR: 151-496) days, decreasing from 378 (IQR: 201-810) days in 2010 to 169 (IQR: 97-281) in 2015. After one year, proportion of patients alive and still in care was significantly lower in those in the lower quartile of time from first encounter to ART (<9 days) than those in the higher quartile (>90 days), 79.9% and 85.2%, respectively (p<0.0001).

Conclusions: In a country with unrestricted rapid access to ART, keeping recently diagnosed HIV infected patients in care remains challenging. Starting ART rapidly did not seem to be profitable for all and every patient.
