A Trial on Ophthalmologist-delivered Health Education on Top of Routine Community Care
8. februar 2022 oppdatert av: Zhongshan Ophthalmic Center, Sun Yat-sen University
The Effectiveness of Ophthalmologist-delivered Health Education on Top of Routine Community Care in Type 2 Diabetic Patients at Risk for Diabetic Retinopathy: A Parallel-group, Randomised Trial
Diabetic retinopathy affects over one third of all people with diabetes and is one of the leading causes of vision loss.
The management of diabetes and its complications should include screening for diabetic retinopathy.
A randomised trial is therefore needed of the use of a simple and widely practicable approach to explore the integration of eye care in managing diabetes.
The trial is designed as a randomised, controlled, superiority trial.
The aim is to explore the effectiveness of ophthalmologist-delivered health education on top of routine community care on blood glucose and eye-related clinical outcomes in type 2 diabetic patients at risk for diabetic retinopathy.

Detaljert beskrivelse
Diabetic retinopathy (DR) is a highly specific vascular complication of diabetes mellitus, with prevalence strongly related to a number of risk factors including the duration of diabetes, the level of glycaemic control, etc. Diabetic retinopathy affects over one third of all people with diabetes and is one of the leading causes of vision loss.
It is recommended that optimising glycaemic control could reduce the risk or slow the progression of diabetic retinopathy, and that the management of diabetes and its complications should include screening for diabetic retinopathy.
A randomised trial is therefore needed of the use of a simple and widely practicable approach to explore the integration of eye care in managing diabetes.
The trial is designed as a randomised, controlled, superiority trial.
The aim is to explore the effectiveness of ophthalmologist-delivered health education on top of routine community care on blood glucose and eye-related clinical outcomes in type 2 diabetic patients at risk for diabetic retinopathy.
Participants will be randomly assigned to either control or intervention group with a 1:1 allocation as per computer-generated random numbers.
A senior onsite manager will monitor participant enrolment over the course of the study.
An ophthalmologist-delivered health education will be offered as the intervention in an individualised, face-to-face counselling session to build awareness on diabetes symptoms, particularly on diabetic retinopathy, and its risk factors with appropriate management.
All subjects, regardless of the group allocation, will be followed up for 12 months.
Baseline and follow-up profiles will be assessed and collected by clinical personnel blind to group allocation.
The intervention arm will be compared against the control for all primary analysis.
The study was partly supported by the Open Research Funds of the State Key Laboratory of Ophthalmology.
Trial results will be disseminated to key stakeholders and the general medical community.
