Abstract Background Patients’ loss to follow-up (LTFU) from tuberculosis treatment and care is a growing worry in Ethiopia. But, available information is inadequate in assessing the time to tuberculosis patient loss to follow-up difference between health centers and a general hospital in Ethiopia. We aimed to assess time to LTFU difference between health centers and a general hospital in rural Ethiopia. Methods We conducted a retrospective cohort study from September 2008 to August 2015 and collected data from September 1 to October 02, 2016. A total of 1341 TB patients with known treatment outcomes were included into the study. Log rank test was used to compare the difference in time to TB patient loss to follow-up between health centers and a general hospital, whereas Cox proportional hazard model was used to assess factors associated with time to loss to follow-up in both settings. Results We reviewed a total of 1341 patient records, and the overall follow-up time was 3074.7 and 3974 person months of observation (PMOs) for TB patients followed at health centers and a general hospital, respectively. The incidence of loss to follow-up rate was 27.3 per 1000 PMOs and 9.6 per 1000 PMOs, at health centers and a general hospital, respectively. From the overall loss to follow-ups that occurred, 55 (65.5%) and 33 (86.8%) of LTFUs occurred during the intensive phase and grew to 78 (92.9%) and 38 (100%) at health center and a general hospital, respectively, at the end of 6-month observation period. Older age (AOR = 1.7, 95%CI, 1.2–2.5, P < 0.001), being a rural resident (AHR = 2.7, 95%CI, 1.6–4.6), HIV reactive (AHR = 2.2, 95%CI, 1.5–3.2), following treatment and care in health center (AHR = 3.38, 95%CI, 2.06–5.53), and living at more than 10 km away from the health facility (AHR = 3.4, 95%CI, 2.1–5.7) were predictors for time to loss to follow-up among TB patients on treatment and care. Conclusion Time to TB patient loss to follow-up between health centers and a general hospital was significant. Loss to follow-up ...
