Abstract：
BACKGROUND: In order for patients to comprehend health related information, it must be written at a level that can be readily understood by the intended population. During 2021 the European Society for Vascular Surgery (ESVS) published a sub-section about information for patients into its Guidelines on the Management of Venous Thrombosis.
METHODS: Nine readability measures were used to evaluate the patient educational material regarding venous thrombosis published by seven medical societies: ESVS, Society for Vascular Medicine (SVM), Society for Vascular Surgery (SVS), Vascular Society for Great Britain and Ireland (VS), Australia and New Zealand Society for Vascular Surgery (ANZSVS), Canadian Society for Vascular Surgery (CSVS) and American Heart Association (AHA).
RESULTS: The mean reading grade level (RGL) for all the 58 recommendations was 10.61 (range 6.4-14.5) and the mean Flesch Reading Ease (FRE) was 56.10 (51.3-62.9), corresponding to a \"fairly difficult\" reading level. The mean RGL of the ESVS recommendations (11.45, 95% CI, 9.90-13.00) was significantly higher than the others. Post-hoc analysis determined a significant difference between the ESVS and the SVS (10.86, 95% CI, 9.84-11.91) recommendations (P=0.005). All the patient\'s education information published by the medical societies presented a RGL higher than recommended. The fifteen sub-sections of the information for patients included into the ESVS clinical guidelines presented a mean RGL above 9.5 points, revealing that no one (0%) was written at or below the recommended GRL. The mean FRE was 47.63 (28.2-61.6), corresponding to a \"difficult\" reading level.
CONCLUSIONS: Venous thrombosis patient educational materials produced by leading medical societies have readability scores that are above the recommended levels. The innovative patient\'s information included into the ESVS venous thrombosis guidelines represents an important advance in the amelioration of the medical information for patients, but their readability should be improved to adapt the understanding to the general population.

摘要：
背景：为了让患者理解健康相关信息，它必须写在一个水平，可以很容易理解的预期人群。2021年，欧洲血管外科学会（ESVS）在其静脉血栓管理指南中发布了有关患者信息的小节。
方法：使用了九种可读性措施来评估七个医学学会发表的有关静脉血栓形成的患者教育材料：ESVS，血管医学学会（SVM），血管外科学会（SVS），大不列颠及爱尔兰血管学会（VS），澳大利亚和新西兰血管外科学会（ANZSVS），加拿大血管外科学会（CSVS）和美国心脏协会（AHA）。
结果：所有58项建议的平均阅读等级水平（RGL）为10.61（范围6.4-14.5），平均Flesch阅读速度（FRE）为56.10（51.3-62.9），对应于“相当困难”的阅读水平。ESVS建议的平均RGL（11.45，95％CI，9.90-13.00）明显高于其他建议。事后分析确定了ESVS和SVS之间的显着差异（10.86，95％CI，9.84-11.91）建议（P=0.005）。医学会发布的所有患者教育信息的RGL均高于建议。纳入ESVS临床指南的患者信息的15个小节显示平均RGL高于9.5分，揭示没有人(0%)被写在或低于推荐的GRL。平均FRE为47.63（28.2-61.6），对应于“困难”阅读水平。
结论：由主要医学团体制作的静脉血栓形成患者教育材料的可读性评分高于推荐水平。ESVS静脉血栓形成指南中包含的创新患者信息代表了改善患者医疗信息的重要进展。但是它们的可读性应该提高，以适应普通人群的理解。
