“…Patient disease awareness could be insufficient as reported by a study from Hong Kong [ 28 ]. Several studies [ 29 , 30 ] focus on reasons for non-attendance (dropouts and never attendance). An overview of the total screening attendance of the Danish diabetes population does not exist, as The Danish Registry of Diabetic Retinopathy only reports patients who have been screened and not the total diabetes population [ 31 ].…”

Aims To evaluate diabetic retinopathy (DR) screening incidence in a universal healthcare system. Methods Registry-based cohort study based on a Danish regional population from 2009 to 2018. Individuals with diabetes were identified by medication. Screening attendance was estimated by surrogate measures using local and nationwide databases reported by cumulative incidence. Results 18,832 patients were included. By the end of the first year, the cumulative incidence of screening for DR was 60.2% and by the end of the second year 74.2%. The cumulative incidence was 93.9% overall, 97.7% for patients with type 1 diabetes (T1D) and 93.4% for patients with type 2 diabetes. Screening proportions per 1, 2 and 5 years were calculated. Females, patients with T1D, and patients attending screening at hospitals had a higher Hazard Ratio of 1.084, 1.157, and 1.573, respectively. The Cochran–Armitage trend test indicated increased screening frequency from 2009 to 2018. Validation of DR screening was done at hospitals with a mean positive predictive value of 86.78%. Cumulative incidence curves showed a small right shift when censoring the first, second and third screening visits. Conclusions Nearly all patients were screened for DR over a 5-year timespan. Female patients with T1D who attended screening at hospitals were significantly more likely to be screened. Validation of screening visits at hospitals was reported with a high mean positive predictive value. Most other studies, to the best of our knowledge, only report screening attendance for patients already enrolled in a DR screening programme. This study describes the overall screening attendance for the total eligible diabetes population.

“…Since the early 2000s, there has been robust uptake of DR screening programs worldwide, driving 2019 screening rates to >80% in the United Kingdom and >70% in Denmark (8,9). Screening rates in the United States are lower, with just 65% of individuals with diabetes undergoing annual DR screening in 2019 (10).…”

“…This review found that patients who belong to "ethnic minorities" or "socio-economic deprived" groups were less likely to attend DR screening and repeated non-attendance was associated with a higher risk of VTDR [174]. This has been confirmed in the Danish population in two recent register studies [175,176]. Many studies which focus on screening attendance or non-attendance are register based, and do not specify whether non-attendants included are drop-outs or never attendants.…”
