To analyse the surgical intervention rate (SIR), best spectacle-corrected visual acuity (BSCVA) and disparities in access to public-funded cataract surgery in New Zealand. The New Zealand Ministry of Health uses the National Prioritisation Web Service (NPWS) to prioritise all patients for public-funded cataract surgery. BSCVA at prioritisation, ethnic, demographic and geographic disparities have not previously been assessed.A retrospective cohort study. Between November 2014 and March 2019, 61,095 prioritisation events for 44,403 unique patients were identified. Cataract prioritisation events extracted from the NPWS were merged with date of birth and ethnicity extracted from the National Health Index database. All data were de-identified prior to statistical analysis.Mean age at prioritisation was 74.4 years, with female preponderance (56%). Overall ethnicity was 'European' in 69.8% and 'New Zealand Māori' in 9.6%. Mean Snellen BSCVA was 6/30-2 (prioritised eye), and 6/12-1 (binocular). Māori and Pasifika presented on average 10 years earlier than other ethnic groups with significantly worse BSCVA. Surgery was approved in 74.4% of prioritisation events with mean Snellen BSCVA of 6/38-2. Only 34.9% of New Zealand patients had Snellen BSCVA of 6/12 or better in the prioritised eye, compared to 58.4% in the European Union. Cataract SIR varied by region.New Zealand's cataract SIR is lower than most Organisation for Economic Co-operation and Development countries and patients have significantly worse BSCVA at prioritisation. Access to cataract surgery in New Zealand varies according to region. Māori and Pasifika present younger with worse BSCVA, suggesting potential barriers in accessing timely referral and prioritisation. |
