Validation of priority criteria for cataract extraction.

Area of Science:

• Ophthalmology
• Health Services Research

Background:

• Cataract prevalence and demand for surgery are rising, leading to patient waiting lists.
• Effective prioritization is crucial for managing surgical demand and optimizing patient outcomes.

Purpose of the Study:

• To validate a previously developed priority scoring system for cataract extraction.
• To assess the system's effectiveness in predicting gains in visual acuity (VA) and health-related quality of life (HRQoL).

Main Methods:

• A prospective cohort of 5257 patients awaiting cataract surgery in Spain was studied.
• A validated prioritization criteria system based on RAND/UCLA appropriateness methodology was applied.
• Data included demographics, clinical variables, VA, and the Visual Function Index (VF-14) pre- and post-intervention.

Main Results:

• High-priority patients showed significantly greater improvements in VA and HRQoL compared to intermediate or low-priority groups (P < 0.0001).
• These improvements persisted after adjusting for baseline VA and VF-14 scores.
• Intervention times did not differ between priority groups.

Conclusions:

• The developed priority score effectively identifies patients who will gain the most from cataract extraction.
• Implementing this tool can lead to a more equitable and rational approach to prioritizing patients for surgery.
