Characteristics of and outcomes in HIV-infected patients who return to care after loss to follow-up

The objective of this study was to evaluate the characteristics of and outcomes in HIV-infected patients who returned to care after loss to follow-up (LTFU) in Northern France, between 1997 and 2006. Among the 1007 patients who were followed, 135 patients (13.4%) were LTFU during the study period. Of these 135, 74 (54.8%) returned to care after LTFU. The median duration of LTFU was 19 months. Upon returning to care, 33 out of 74 patients (44.6%) had CD4 cell counts less than 200/mm(3) and/or AIDS. Patients who returned to care after LTFU were five times more likely to die than patients who attended clinic regularly.
