PURPOSE
To assess the validity of the Cataract Priority Criteria Score (PCS), developed by the Western Canada Waiting List (WCWL) Project to determine patient prioritization for cataract surgery.
METHODS
Ophthalmologists assessed consecutive patients with the PCS and a visual analogue scale of urgency (VAS Urgency). Patients were mailed questionnaires pre- and post-surgery. Outcome measures were the Visual Function Assessment (VFA), EuroQol (EQ-5D), and best-corrected visual acuity.
RESULTS
The sample of 253 patients was 58% female (mean age, 73.7 years); 166 completed pre-and post-surgery VFA. The correlation of the PCS and VAS Urgency was 0.65 (p = 0.000). Adjusting for age, first or second eye surgery, and post-operative complication, the PCS predicted improvement in the VFA and visual acuity (p < .05).
CONCLUSIONS
These data provide some evidence to support the convergent and predictive validity of the PCS. Multiple patient outcomes should be used in the evaluation of the validity of priority scores.
目的
评估由加拿大西部等候名单（WCWL）项目制定的白内障优先标准评分（PCS）在确定白内障手术患者优先顺序方面的有效性。
方法
眼科医生使用PCS和视觉模拟紧急程度量表（VAS紧急程度）对连续的患者进行评估。在手术前后向患者邮寄问卷。结果指标包括视觉功能评估（VFA）、欧洲五维度健康量表（EQ-5D）和最佳矫正视力。
结果
253名患者的样本中58%为女性（平均年龄73.7岁）；166名患者完成了手术前后的VFA。PCS与VAS紧急程度的相关性为0.65（p = 0.000）。在对年龄、单眼或双眼手术以及术后并发症进行校正后，PCS可预测VFA和视力的改善情况（p < 0.05）。
结论
这些数据为支持PCS的收敛效度和预测效度提供了一些证据。在评估优先评分的有效性时应使用多种患者结局指标。
