Abstract/OtherAbstract:
Background: We estimated the impact of loss to follow-up (LTFU) on the mortality rate amongst HIV-1 infected patients in Curaçao. Methods: A total of 214 therapy-naïve HIV-1 infected patients aged 15 years or older upon entering into HIV care between January 2005 and July 2009 were included. Persons who discontinued follow-up for more than 365 days were defined as LTFU and traced with the aim of registering their vital status. If no personal contact could be made, data were matched with the Curaçao National Death Registry. Mortality rates were estimated before and after starting combined antireteroviral therapy (cART). We used log-rank tests to compare survival rates amongst patients LTFU and patients who experienced continuous follow-up. Results: Pre-cART mortality in patients LTFU was similar to pre-cART mortality in those with continuous follow-up (p=0.79). All pre-cART deaths occurred within 6 months after entry. Late diagnosis was predictive for a shorter time to death after entry. Adjusting for those who were LTFU, the mortality rate after starting cART increased from 4.3 to 5.5 per 100 person years of observation (p=0.06). Mortality after starting cART was highest in the first 2 months after starting cART, especially for those who had late disease stage. Mortality rates were lower in patients with continuous follow-up compared to LTFUs (p<0.001). Conclusion: Mortality rates in HIV-1 infected patients who have started cART in Curaçao are underestimated as a result of inefficient patient administration combined with people starting cART at very late disease stage. Monitoring HIV treatment could help reducing the risk of LTFU and may improve the effect of treatment.
