沟通风险是医疗决策中的一项重要活动；然而，算术并不是美国公众的通用技能。我们检验了这样一种假设，即当使用视觉描述而不是抽象的数字并取决于疾病的严重程度时，有关使用羟基脲治疗镰状细胞病儿童的数字风险信息将引起不同的风险评估反应。81名患有镰状细胞疾病的儿童的父母参与了一项调查，在这项调查中，羟基尿素首次被描述为具有一定的出生缺陷和癌症风险。然后，父母表示，假设他们同意治疗以帮助孩子，他们的风险最高。以抽象的数字、饼图和1000人直方图的形式重复风险演示。CHI(2)分析比较了不同呈现形式的高风险和低风险评估，表明视觉描述之间的一致性很高，但抽象数字与视觉描述的一致性较低。当数据以数字表示时，患有SC和其他不太严重的SCD儿童的父母不太愿意接受比SS儿童更高的风险。鉴于早些时候人们对美国人“算术”能力差的担忧，对风险的视觉描述可能是健康教育和医疗决策中常规沟通的有效工具。
Communicating risk is an important activity in medical decision-making; yet, numeracy is not a universal skill among the American public. We examined the hypothesis that numerical risk information about the use of hydroxyurea for children with sickle cell disease would elicit different risk assessment responses when visual depictions were used instead of abstract numbers and depending on the disease severity. Parents of 81 children with sickle cell disease participated in a survey in which hydroxyurea was first described as carrying a certain chance of risk for both birth defects and cancer. Then, the parents indicated the highest risk at which they would hypothetically consent to the treatment to help their child. Risk presentations were repeated with abstract numerical, pie graph, and 1000 people histogram formats. The chi(2) analyses comparing high-risk to low-risk assessment across presentation formats showed high consistency between visual depictions but low consistency of abstract numerical with visual depictions. The parents of children with SC and other less severe types of SCD were less willing to accept higher risk than those with SS when the data were presented numerically. Given earlier concerns about poor "numeracy" in the US population, visual depictions of risk could be an effective tool for routine communication in health education and medical decision-making.
