The purpose of this study was to assess the readability and quality of patient information regarding mammography, tomosynthesis, and breast density on the websites of ACR-designated mammography Breast Imaging Centers of Excellence (BICOEs) in the United States.
In this institutional review board-exempt study, websites of mammography BICOEs were identified by state. Websites were assessed for presence of patient education material on screening mammography, tomosynthesis, and breast density. This material was then assessed for readability using five well-established readability metrics (Flesch-Kincaid Reading Ease Index, Flesch-Kincaid Grade Level, Gunning-Fog Score, Coleman-Liau Index, and Simple Measure of Gobbledygook Index) and for quality using the DISCERN instrument.
We identified 1,482 BICOE centers, of which 1,451 (98%) had websites; 79% (1,156 of 1,451) of websites had information on screening mammography, 45% (657 of 1,451) on tomosynthesis, and 16% (228 of 1,451) on breast density. Readability analysis showed that the overall average grade level of patient information was 12.4. Average readability grade levels by tested indexes were Flesch-Kincaid Grade Level of 11.5, Gunning-Fog Score of 14.1, Coleman-Liau Index of 14.1, and Simple Measure of Gobbledygook Index of 10.9. The average Flesch-Kincaid Reading Ease score was 45, with 0 being the most difficult and 100 being the easiest text to read. The overall DISCERN score nationally was 2.61 of 5 (with 5 representing the highest quality).
Although most BICOEs have patient education material on their websites regarding mammography and some have information regarding tomosynthesis and breast density, the average readability grade level of this material is more than double the nationally recommended readability grade level of 6 for health care information. Additionally, the overall quality of this material is relatively low per established quality metrics.
本研究旨在评估美国放射学会指定的乳腺摄影卓越影像中心（BICOEs）网站上有关乳腺摄影、断层合成和乳腺密度的患者信息的可读性和质量。
在这项无需机构审查委员会批准的研究中，按州确定了乳腺摄影BICOEs的网站。评估网站上是否存在关于筛查乳腺摄影、断层合成和乳腺密度的患者教育材料。然后使用五个成熟的可读性指标（弗莱什-金凯德阅读易读指数、弗莱什-金凯德年级水平、冈宁-福格分数、科尔曼-廖指数和胡言乱语简易度量指数）评估该材料的可读性，并使用DISCERN工具评估其质量。
我们确定了1482个BICOE中心，其中1451个（98%）有网站；79%（1451个中的1156个）的网站有关于筛查乳腺摄影的信息，45%（1451个中的657个）有关于断层合成的信息，16%（1451个中的228个）有关于乳腺密度的信息。可读性分析表明，患者信息的总体平均年级水平为12.4。按测试指标的平均可读性年级水平为：弗莱什-金凯德年级水平为11.5，冈宁-福格分数为14.1，科尔曼-廖指数为14.1，胡言乱语简易度量指数为10.9。平均弗莱什-金凯德阅读易读分数为45，0表示最难读懂，100表示最易读懂的文本。全国范围内的总体DISCERN评分为5分中的2.61分（5分代表最高质量）。
虽然大多数BICOEs在其网站上有关于乳腺摄影的患者教育材料，一些有关于断层合成和乳腺密度的信息，但该材料的平均可读性年级水平比全国推荐的医疗保健信息可读性年级水平6高出一倍多。此外，根据既定的质量指标，该材料的总体质量相对较低。
