Summary
The visual analogue scale (VAS) for prioritizing cataract surgery shows high variability among ophthalmologists. An objective scoring system may improve patient prioritization and service delivery.
Area of Science:
- Ophthalmology
- Health Services Research
Background:
- Cataract surgery prioritization is crucial for efficient healthcare delivery.
- Current methods may lack objectivity, leading to variability in patient selection.
Purpose of the Study:
- To evaluate the variability of the visual analogue scale (VAS) in prioritizing elective cataract surgery.
- To assess the feasibility of a cataract surgery prioritization (CSP) scoring system.
Main Methods:
- Prospective recruitment of patients listed for cataract surgery.
- Ophthalmologists used VAS to rate surgical urgency; CSP scores were calculated based on New Zealand criteria.
- Correlation analysis between VAS and CSP scores to determine inter-ophthalmologist variability.
Main Results:
- A positive correlation was found between VAS and CSP scores (Spearman rho=0.407, P < 0.001).
- Significant variation existed among ophthalmologists in VAS usage.
- Patients with severe binocular vision impairment were not consistently prioritized.
Conclusions:
- The subjective nature of VAS may lead to suboptimal prioritization of cataract surgery.
- Implementing an objective, criteria-validated CSP system could enhance patient stratification and service provision.
