目的：评估急诊科(ED)患者有限计算能力的患病率和人口学差异。方法：我们对2000-2001年和2006年两次横断面研究中的亚危重ED患者进行了研究。我们招募了来自美国17个州28个急诊室的959名成年患者，并基于4个有效的问题测量了计算能力。结果：对个别计算问题的正确回答率从15%到68%不等；只有11%的参与者正确回答了所有问题。几个人口统计特征与正确答案的频率独立相关，包括年龄(OR 0.92[95%可信区间(0)，0.87-0.97]每5年向上箭头)，种族/民族(与白人相比：黑人：或0.35[95%CI，0.20-0.63]；拉美裔[95%CI，0.19-0.69]、教育程度(OR 4.74[95%CI，2.01-11.14]与非高中毕业生相比)、医疗保险(OR 1.70[95%CI，1.06-2.71]对于有私人保险的人)、收入(OR 1.13[95%CI，1.05-1.22])。结论：与普通人群相比，我们发现ED患者中有限计算能力的患病率更高。显著的人口统计学差异与之前对一般健康知识的观察一致。实践意义：更好地理解有限计算的高流行率可能会指导医疗保健提供者简化信息并更有效地交流健康信息。(C)2008爱思唯尔爱尔兰有限公司。保留所有权利。
Objective: To estimate the prevalence and demographic disparities in limited numeracy among emergency department (ED) patients.Methods: We performed two cross-sectional studies of ED patients with sub-critical illness in 2000-2001 and 2006. We enrolled 959 adult patients from 28 EDs in 17 US states and measured numeracy based on four validated questions.Results: Rates of correct responses for individual numeracy questions ranged from 15% to 68%; only 11 % of participants answered all questions correctly. Several demographic characteristics were independently associated with frequency of correct answers, including age (OR 0.92 [95% confidence interval (0), 0.87-0.97] per up arrow 5 years), race/ethnicity (compared to whites: OR 0.35 for blacks [95%CI, 0.20-0.63]; and OR 0.36 for Hispanics [95%CI, 0.19-0.69]), education (OR 4.74 [95%CI, 2.01-11.14] for high school graduates vs. not), health insurance (OR 1.70 [95%CI, 1.06-2.71] for those with private insurance vs. not), and income (OR 1.13 [95%CI, 1.05-1.22] per up arrow$10,000).Conclusion: We found a higher prevalence of limited numeracy among ED patients compared to the general population. Significant demographic disparities are consistent with previous observations for general health literacy.Practice implications: Greater understanding of the high prevalence of limited numeracy may guide healthcare providers to simplify messages and communicate health information more effectively.
