Abstract
Diabetic retinopathy (DR), a prevalent microvascular complication of diabetes mellitus (DM), can be prevented with early detection and timely intervention. DR is asymptomatic in its early stages, highlighting the importance of screening for accurate referral and effective management. Multiple barriers impede access to diabetic retinopathy screening (DRS), creating significant public health challenges in regions with high DM prevalence. This study explores the perspectives of people with DM (PwDM) and healthcare providers (HCP) on these barriers. A qualitative study using in-depth interviews (IDI) was conducted between October 2022 and January 2023 in Punjab and Chandigarh. Through purposive sampling, IDIs were conducted with 7 PwDM and 19 HCPs, including retina specialists, ophthalmologists, optometrists, medical officers (MO), Community Health Officers (CHO), and ASHA workers from various public health facilities. A semi-structured topic guide facilitated the interviews, and thematic analysis was applied, utilizing the healthcare access barrier (HCAB) model as a framework. The study identified financial barriers due to insurance unawareness and employment constraints. Structural challenges included insufficient DRS infrastructure, untrained staff, the need for accompaniment, and limited access to screening sites. Limited awareness and misconceptions about DR characterized cognitive barriers, while psychological barriers involved mistrust of the health system, anxiety, and frustration from low vision. Addressing these issues is essential to improve DRS uptake and eye health outcomes. Managing diabetes and VTDR is challenging, highlighting the need for community-level DRS. Enhancing DR awareness and promoting public health insurance benefits are crucial for overcoming barriers and improving screening rates.
