Background:There is concern about the increasing rates of loss to follow-up(LTFU)among pre-antiretroviral therapy(pre-ART)patients in Ethiopia.Little information is available regarding the time when pre-ART patients are lost to follow-up in the country.This study assessed the time when LTFU occurs as well as the associated factors among adults enrolled in pre-ART care in an Ethiopian rural hospital.Methods:Data of all adult pre-ART patients enrolled at the Sheka Zonal Hospital between 2010 and 2013 were reviewed.Patients were considered lost to follow-up if they failed to keep scheduled appointments for more than 90 days.The Cox proportional hazards regression model was used to assess factors associated with time until LTFU.The Kaplan-Meier survival table was used to compare the LTFU experiences of patients,segregated by significant predictors.Results:A total of 626 pre-ART patients were followed for 319.92 person-years of observation(PYOs)from enrolment to pre-ART outcomes,with an overall LTFU rate of 55.8 per 100 PYOs.A total of 178(28.4%)pre-ART patients were lost to follow-up,93%of which occurred within the first six months.The median follow-up time was 6.13 months.The independent predictors included:not having been started on co-trimoxazole prophylaxis(adjusted hazard ratio[AHR]=1.77,95%confidence interval[CI],1.12–2.79),a baseline CD4 count of or above 350 cells/mm3(AHR=1.87,95%CI,1.02–3.45),and an undisclosed HIV status(AHR=3.04,95%CI,2.07–4.45).Conclusion:A significant proportion of pre-ART patients is lost to follow-up.Not having been started on co-trimoxazole prophylaxis,presenting to care with a baseline CD4 cell count≥350 cells/mm3,and an undisclosed HIV status were significant predictors of LTFU among pre-ART patients.Thus,close monitoring and tracking of patients during this period is highly recommended.Those patients with identified risk factors deserve special attention.
