GP2DRS (Diabetic eye screening programme)

Screening is the process of identifying people who appear healthy, but who may be at increased risk of a disease or condition. It's different to diagnosis and there will always be some false positive and false negative results.

Purpose and outline

Evidence shows that early identification and treatment of diabetic eye disease could reduce sight loss. The main treatment for diabetic retinopathy is laser surgery.
The eligible population for diabetic eye screening are people with type 1 and type 2 diabetes aged 12 or over. Those already under the care of an ophthalmology specialist for the condition are not invited for screening. The programme offers pregnant women with type 1 or type 2 diabetes additional tests because of the risk of developing retinopathy.

Business rules

Following the introduction of SNOMED and the move to clinical reference sets (refsets), there was the requirement to update the business rules to account for these changes.  

Like Read V2/CTV3 there are several SNOMED code releases throughout the year. NHS Digital highlight any impact of these code releases and propose specific changes to the refsets (for PHE to consider) to ensure the objectives of the data extract continue to be met.

NHS Digital will maintain these refsets in with feedback provided by PHE. The SNOMED version of the GP2DRS extract will be the primary data collection going forwards, subject to PHE completing its quality assurance of this extract. Once this has been achieved, the previous Read V2/CTV3 version will be retired.
