Problem

The National Cataract Audit (NOA) annually reports results for contributing centres as part of the national programs of clinical audits. There is variation between centres in the recording of data for different parts of the patient pathway, and by publishing the results the audit aims to reduce this variation.

Purpose

To show the audit results for GHNHSFT in relation to other contributing NOA centres for cataract surgery performed between 1st September 2016 and 31st August 2017.

Methods

Comparison of metrics between GHNHSFT and all other contributing NOA centres for the most recently reported audit year. Metrics reported are the percentage of operations with a pre-operative visual acuity (VA) measurement, a post-operative VA measurement, both VA measurements, case complexity posterior capsular rupture (PCR) rate and the VA loss rate

Results

From 182,761 cataract operations performed in 82 centres, a pre-operative VA was recorded for 91.5% of operations. From 158,858 operations, a post-operative VA was recorded for 75.7% of operations and both VA measurements for 71.7% of operations. The overall case complexity PCR rate was 0.89% and the overall VA loss rate was 0.64%.

For GHNHSFT, a pre-operative VA measurement was recorded for 92.8% of 3,521 operations, a post-operative VA for 86.0% of 2,989 operations, and both VA measurements for 80.8% of operations. The overall case complexity PCR rate was 1.05% and the overall VA loss rate was 0.29%.

Conclusions

The metric results for GHNHSFT compare favourably with the audit estimates for all contributing centres.
