INTRODUCTION: Over time there has been substantial improvement in antiretroviral treatment (ART) programmes, including expansion of services and increased patient engagement. We describe time trends in, and factors associated with, loss to follow-up (LTFU) in HIV4 positive patients receiving ART in Asia.

METHODS: Analysis included HIV-positive adults initiating ART in 2003-2013 at seven ART programmes in Asia. Patients LTFU had not attended the clinic for ≥180days, had not died or transferred to another clinic. Patients were censored at recent clinic visit, follow-up to January 2014. We used cumulative incidence to compare LTFU and mortality between years of ART initiation. Factors associated with LTFU were evaluated using a competing risks regression model, adjusted for clinical site.

RESULTS: A total of 8,305 patients were included. There were 743 patients LTFU and 352 deaths over 26,217 person-years (pys), a crude LTFU and mortality rate of 2.83 (2.64-3.05) per 100 pys and 1.34 (1.21-1.49) per 100 pys, respectively. At 24 months, the cumulative LTFU incidence increased from 4.3%(2.9-6.1%) in 2003-05 to 8.1%(7.1-9.2%) in 2006-09, then decreased to 6.7%(5.9-7.5%) in 2010-13. Concurrently, the cumulative mortality incidence decreased from 6.2%(4.5-8.2%) in 2003-05 to 3.3%(2.8-3.9%) in 2010-13. The risk of LTFU reduced in 2010-13 compared to 2006-09 (adjusted subhazard ratio=0.73, 0.69-20 0.99).

CONCLUSIONS: LTFU rates in HIV-positive patients receiving ART in our clinical sites have varied by the year of ART initiation, with rates declining in recent years while mortality rates have remained stable. Further increases in site-level resources are likely to contribute to additional reductions in LTFU for patients initiating in subsequent years.
