Understanding Barriers to Glaucoma Treatment Adherence among Participants in South India

摘要

abstract_textpPurpose: Data on glaucoma treatment barriers in South India is limited; improved knowledge of barriers could advance disease self-management. We aimed to understand glaucoma treatment barriers in South India. Methods: Glaucoma patients = 18 taking = 1 medication at the Aravind Eye Hospital were screened with a validated medication adherence tool. Patients who self-reported poor adherence and/or were 3 months late for follow-up completed semi-structured interviews on treatment barriers. Interviews were audio-recorded, transcribed, translated and back-translated to ensure accuracy. Researchers used grounded theory to code the transcripts and identify themes using NVivo 11.0. Demographic and clinical characteristics were abstracted from the medical record. Results: 70/167 (42%) had poor self-reported adherence to drops. The 45 interviewed were 62 +/- 12 years and took 1.6 +/- 0.7 drops. Forty-two (93%) were non-adherent to medication and 21 (47%) were late for follow-up. Top barriers to medication adherence were difficulty obtaining drops (20, 44%), being busy (18, 40%), and the expense (17, 38%). Top barriers to appointment follow-up were distance to the hospital (21, 47%), expense (20, 44%), and no escort (15, 33%). Other important barriers included mistrust in the health system, poor knowledge of glaucoma and family needs. Conclusions: Previously, 6% of glaucoma patients in South India self-reported poor medication adherence; the 42% identified in this study is in line with glaucoma medication adherence rates globally. Complex factors caused high rates of non-adherence. Societal-level interventions that address systemic barriers and counselling that supports patients' and families' motivation for behaviour change should be implemented./p/abstract_text
