Background

Venous thromboembolism (VTE) is a critical complication of varicose vein treatments. The Caprini Score (CS) is an established tool to assess patients’ VTE risks. One disadvantage is the number of questions required, some of them referring to a low incidence of disease, even lower in patients seeking an elective procedure. These elements take time and may result in filling errors if the CS is not filled out by a properly trained health professional.

Objective

To establish a response pattern in CS, with emphasis on questions that usually have a negative answer and propose a simpler adaptative digital version without changing the original structure of the tool.

Methods

two hundred and twenty-seven patients in the pre-surgical treatment of varicose veins were enrolled prospectively and submitted to the CS evaluation.

Results

The pattern of dichotomous responses could be divided arbitrarily into four subgroups considering the percentage of positive responses: none (11 items), less than 3% (13 items), between 3% and 20% (5 items), and more than 20% (8 items). Of the 12 CS questions related to illnesses that occurred in the last month, ten had had no responses, and 2 were less than 3%.

Conclusion

There is a pattern in the CS responses of patients with an indication of surgical treatment of varicose veins. Many of the CS questions are not helpful in this scenario and may result in filling errors performed by untrained providers. An adaptative version of the CS might benefit varicose veins surgery VTE risk stratification

一项前瞻性研究评估对 Caprini 评分的反应模式以预防静脉曲张介入治疗后的静脉血栓栓塞

背景

静脉血栓栓塞症 (VTE) 是静脉曲张治疗的严重并发症。Caprini 评分 (CS) 是评估患者 VTE 风险的成熟工具。一个缺点是所需问题的数量，其中一些是指疾病的发生率较低，在寻求选择性手术的患者中甚至更低。如果 CS 不是由经过适当培训的卫生专业人员填写，这些要素需要时间并且可能导致填写错误。

客观的

在 CS 中建立响应模式，重点关注通常有否定答案的问题，并在不改变工具原始结构的情况下提出更简单的自适应数字版本。

方法

前瞻性招募了 227 名接受静脉曲张术前治疗的患者，并提交给 CS 评估。

结果

考虑到积极反应的百分比，二分反应模式可以任意分为四个亚组：无（11 项）、小于 3%（13 项）、3% 到 20%（5 项）和超过 20% （8 项）。在上个月发生的与疾病相关的 12 个 CS 问题中，有 10 个没有回答，2 个低于 3%。

结论

有静脉曲张手术治疗指征的患者的 CS 反应存在模式。许多 CS 问题在这种情况下没有帮助，并且可能导致未经培训的提供者执行填写错误。CS 的适应性版本可能有利于静脉曲张手术 VTE 风险分层
