Type 2 Diabetic Retinopathy Screening in a General Practice: A Five-Year Retrospective Analysis

Area of Science:

• Ophthalmology
• Endocrinology
• Primary Care Medicine

Background:

• Diabetic retinopathy is a leading cause of preventable blindness.
• National Institute of Clinical Excellence (NICE) guidelines set standards for diabetic retinopathy screening in type 2 diabetes mellitus.
• Effective screening in primary care is crucial for early detection and management.

Purpose of the Study:

• To evaluate current diabetic retinopathy screening practices in primary care against NICE guidelines for type 2 diabetes.
• To determine adherence to recommended screening intervals: within three months of referral and annually thereafter.

Main Methods:

• A retrospective audit of 50 patient records from a single general practice was conducted.
• Data included patient demographics, diabetes diagnosis dates, and screening attendance.
• Inclusion criteria focused on patients on the type 2 diabetes register between 2013 and 2018.

Main Results:

• Only 16.0% of individuals with type 2 diabetes met NICE guideline standards for retinal screening.
• Among non-adherent patients, 59.5% had intervals exceeding three months from diagnosis to first screening.
• A significant 64.3% experienced screening intervals longer than one year.

Conclusions:

• Current diabetic retinopathy screening in primary care requires substantial improvement to meet NICE standards.
• Interventions are needed to enhance awareness among general practitioners and practice nurses regarding timely screening.
• Ensuring timely initial and annual retinal screenings is vital for all individuals with diabetes.
