Objective: This study aimed to establish the utility values of different health states associated with diabetic retinopathy in a Brazilian sample to provide input to model-based economic evaluations.
Methods: This cross-sectional study was performed in a sample of patients with type 2 diabetes mellitus (T2D) who underwent teleophthalmology screening at a primary care service from 2014 to 2016. Five diabetic retinopathy health states were defined: absent, non-sight-threatening, sight-threatening, and bilateral blindness.
Objective: To perform a cost-utility analysis of diabetic retinopathy (DR) screening strategies from the perspective of the Brazilian Public Healthcare System.
Methods: A model-based economic evaluation was performed to estimate the incremental costs per quality-adjusted life-year (QALY) gained between three DR screening strategies: (1) the opportunistic ophthalmology referral-based (usual practice), (2) the systematic ophthalmology referral-based, and (3) the systematic teleophthalmology-based. The target population included individuals with type 2 diabetes (T2D) aged 40 years, without retinopathy, followed over a 40-year time horizon.
Introduction: We must study alternatives to structure an effective diabetic retinopathy screening program for Brazilian public health system.
Objectives: Evaluate the diagnostic performance of retinal digital photography for diabetic retinopathy screening in primary care, accuracy of the family physician in diabetic retinopathy identification compared to the ophthalmologist, and the need for dilation.
Methodology: In a primary care service were performed retinal photographs with non-mydriatic Retinal Camera in 219 type 2 diabetic patients with and without medication mydriasis.
