Abstract

BACKGROUND/AIMS: To examine the association between sociodemographic characteristics and attendance at Hospital Eye Service (HES) referrals from the Diabetic Eye Screening Programme (DESP), in a large, ethnically diverse urban population. METHODS: Retrospective cohort study (4 January 2016-12 August 2019) of people with diabetic retinopathy (DR) referred from an English DESP to a tertiary referral eye hospital. We conducted a multivariable logistic regression with attendance as the primary outcome, controlling for age, sex, ethnicity, Index of Multiple Deprivation, best eye visual acuity and baseline DR grade. RESULTS: Of 7793 people referred (mean age 64 years, 62.6% male, 13.9% white, 12.5% black, 25.3% South Asian, 6.5% any other Asian background, 19.3% no recorded ethnicity and 20.9% of 'Other' ethnic origin), 69% attended. Compared with white individuals, people of black ethnic origin were similarly likely to attend. South Asians and those of other Asian backgrounds were more likely, and people with 'Other' or missing ethnicity were less likely to attend. Those with higher levels of deprivation, younger (aged 18-45 years) and older (76-90 years) age groups and worse visual acuity were less likely to attend, whereas people identified as having proliferative DR in both eyes were more likely to attend. CONCLUSION: Sociodemographic patterns in attendance after referral from the DESP to the HES exist, and these do not appear to explain ethnic differences in more severe sight-threatening DR, suggesting other explanations. More work is needed to understand and reduce inequalities in HES attendance.
