To determine the feasibility and reliability of an online patient completed Aberdeen Varicose Vein Questionnaire (AVVQ) as a tool to guide specialist referral.
This was a prospective qualitative and quantitative study. One hundred and six patients completed an online questionnaire. Some 43 (40%) completed the AVVQ questionnaire at home and 63 (60%) did it immediately before their appointment. Venous Clinical Severity Score (VCSS) and CEAP grades were assigned by a consultant vascular surgeon. In 11 patients, the questionnaire was repeated at the time of surgery to assess reproducibility and bias.
The AVVQ correlated with the specialist's VCSS scores (Spearman coefficient 0.795; p < 0.01) and similarly with CEAP grade (P < 0.01, ANOVA test). AVVQ was reproducible with close agreement (Spearman coefficient 0.89; p < 0.01) between both 1st AVVQ score of 21.61 (sd 10.26; range 6.12-40.14) and 2nd AVVQ score of 21.03 (sd 10.50 range 4.51-42.57). Patients' feedback about the online AVVQ was positive.
An online questionnaire is acceptable to patients, correlates with clinical findings and using a threshold value could be used by healthcare Commissioners to guide varicose vein referrals.
确定在线患者完成阿伯丁静脉曲张问卷（AVVQ）作为指导专家转诊工具的可行性和可靠性。
这是一项前瞻性定性和定量研究。106 名患者完成了在线问卷。其中 43 名（40%）在家中完成了 AVVQ 问卷，63 名（60%）在预约前立即完成了问卷。静脉临床严重程度评分（VCSS）和 CEAP 分级由顾问血管外科医生分配。在 11 名患者中，在手术时重复了问卷以评估可重复性和偏差。
AVVQ 与专家的 VCSS 评分相关（Spearman 系数 0.795；p < 0.01），与 CEAP 分级也相关（P < 0.01，ANOVA 检验）。AVVQ 具有可重复性，两次 AVVQ 评分之间具有密切的一致性（Spearman 系数 0.89；p < 0.01），第 1 次 AVVQ 评分为 21.61（标准差 10.26；范围 6.12-40.14），第 2 次 AVVQ 评分为 21.03（标准差 10.50，范围 4.51-42.57）。患者对在线 AVVQ 的反馈是积极的。
在线问卷可被患者接受，与临床发现相关，并且使用阈值可以由医疗保健专员用于指导静脉曲张转诊。
