UH Bristol cataract questionnaire recognised across the UK

A questionnaire developed by UH Bristol is being piloted for use in the national cataract surgery audit in England and will be rolled out across health boards in Wales.

It comes as part of a five-year National Institute for Health Research (NIHR) funded cataract research programme, which is one year away from completion. The last stage aims to develop a tool which will help patients decide, together with their clinician, whether cataract surgery is the right choice for them. As part of the study, a type of questionnaire called a patient reported outcome measure (PROM) was developed for patients to compare their vision before and after cataract surgery.

This cataract-specific PROM (Cat-PROM5) has not only contributed to the next stage of the study, it has been translated into Welsh, with the aim of implementation across Wales as part of the PROMs, patient-reported experience measure (PREMs) and effectiveness programme.

Separately, the Royal College of Ophthalmologists is undertaking a feasibility study on the collection of PROMs for cataract surgery using the Cat-PROM5 tool as part of the National Ophthalmology Database Audit, commissioned by the Health Quality Improvement Partnership. Collection of data from Cat-PROM5 will provide an alternative measure on visual success of cataract surgery and valuable information to improve quality for patients.

Cataract is an extremely common, potentially blinding age related condition, with cataract surgery being the most frequently undertaken surgical procedure on the NHS (~390,000 annually in England).

Before and after surgery vision testing is normally done one eye at a time using an optician's letter chart. Although useful, testing in this way does not capture a patient's everyday experience of their vision. Asking patients about their everyday vision in a structured way allows the patient's perception of their eyesight to be measured.

The NIHR-funded cataract research programme is being conducted across three other NHS centres as well as UH Bristol: Torbay and South Devon NHS Foundation Trust, Gloucestershire Hospitals NHS Foundation Trust and Brighton and Sussex University Hospitals NHS Trust. Additionally, Cardiff University researchers, who have specific expertise in decision aid development, are actively collaborating on this element of the programme.

At UH Bristol, the programme is being undertaken by researchers at the Bristol Eye Hospital.

Chief investigator, Professor John Sparrow, said: "The use of Cat‑PROM5 to gauge patient's self-reported visual difficulties and its relief from surgery will allow the NHS to measure for the first time in a direct way the benefits provided to patients undergoing this extremely common sight changing operation."
