National Ophthalmology Database Audit

The National Ophthalmology Database (NOD) holds a national audit of cataract surgery outcomes from across England and Wales. The NOD team collates and analyses a standardised and nationally agreed cataract surgery database. The raw data is supplied by the centres in England and Wales that provide NHS cataract surgery services. Each year the NOD audit produces an annual report which provides updated benchmark standards of care which can be used by Trusts and surgeons to recognise and action areas for quality improvement.

In 2014 the College was commissioned by the Health Quality Improvement Partnership (HQIP), with funding from NHS England and the Welsh Government, to manage the NOD audit as part of the National Clinical Audit and Patient Outcomes Programme (NCAPOP). This agreement was in place until 31 August 2019, when the RCOphth began delivering the NOD audit independently.

The reports produced from the National Ophthalmology Database audit have steered significant improvement in patient safety and outcomes for cataract surgery in England and Wales. By providing a means for peer-to-peer comparison and a national benchmark for outcomes such as PCR (posterior capsular rupture) complication rate and visual acuity loss, the NOD safeguards patient safety and promotes best practice amongst ophthalmologists and ophthalmology departments.

National Ophthalmology Database annual report on cataract surgery 2019

In September 2019 the third prospective National Ophthalmology Database (NOD) audit report on cataract surgery in England and Wales was published. The annual report and key findings summary are available on the NOD website.

This report, based on data gathered in 2017/18, demonstrated a 37% overall reduction in visual acuity loss and a 38% overall reduction in PCR complications since the audit began in 2010. Of the 217,875 operations analysed only 1.2% were affected by PCR complications. This marks a significant saving of £2million in one year from avoiding PCR. Overall, patients continue to receive high quality cataract surgery care.

National Ophthalmology Database annual report on cataract surgery 2018

The second prospective National Ophthalmology Database (NOD) Audit report on cataract surgery in England and Wales was published on 9 August 2018. The full report and the key findings summary are available on the NOD website.

The report, which includes data on 183,812 eligible cataract operations, shows a 30% reduction in the unadjusted Posterior Capsule Rupture (PCR) rate from 2.0% in 2010 to 1.4% in 2016-2017 which equates to around 2,500 fewer complications annually.

National Ophthalmology Audit feasibility reports for glaucoma, retinal detachment surgery and Age-related Macular Degeneration March 2018

In 2014, HQIP commissioned a National Ophthalmology Audit which included three feasibility studies for electronic audits in AMD, glaucoma and retinal detachment surgery, in addition to the main focus of the National Audit which was for cataract surgery. The reports were published on 22 March 2018 and are available on the NOD website.
