OBJECTIVES: To identify risk factors for loss to follow-up in periodic intravitreal anti-vascular endothelial growth factor injections for the treatment patients with diabetic macular edema, subretinal neovascularization, age-related macular degeneration, and retinal vein occlusion in a single eye center in São Paulo, Brazil.
METHODS: This was a retrospective longitudinal study that gathered information from 992 patients who required intravitreal anti-vascular endothelial growth factor drugs over 6 months. The authors included age, eye disease, laterality, monthly income, distance, and payment mode as risk factors.
RESULTS: Two hundred and seventy patients (29.93%) were lost to follow-up. Multivariate analysis showed age, monthly income, eye involvement, and type of medical assistance independently associated with loss to follow-up. The odds of loss to follow-up were greater among older patients than those less than 50 years (reference), p < 0.001. The odds of loss to follow-up were greater among patients who received unilateral treatment than those who received bilateral injections (p = 0.013). Concerning gross monthly income, there were no differences in the odds of the four salary strata; the data also indicate an absence of difference in the three strata of patients' distance to the clinic. Considering the diagnosis, only age-related macular degeneration showed greater odds of loss to follow-up (p = 0.016). Finally, the data suggest greater odds of loss to follow-up in private patients than in those on a health care plan (p < 0.001).
CONCLUSION: Loss to follow-up is paramount because many patients may remain unassisted concerning their eye diseases. Identifying the risk factors is crucial to enforcing measures to increase adherence and the long-term success of the treatment.
