Electronic health records (EHRs) are promising tools to improve quality and efficiency in health care, but data on their adoption rate are limited. We identified surveys on EHR adoption and assessed their quality. Although surveys returned widely different estimates of EHR use, when available information is limited to studies of high or medium quality, national estimates are possible: Through 2005, approximately 23.9 percent of physicians used EHRs in the ambulatory setting, while 5 percent of hospitals used computerized physician order entry. Large gaps in knowledge, including information about EHR use among safety-net providers, pose critical challenges for the development of policies aimed at speeding adoption.
电子健康记录（EHRs）是有望提高医疗保健质量和效率的工具，但关于其采用率的数据有限。我们识别了有关EHR采用情况的调查并评估了其质量。尽管各项调查得出的EHR使用估计值差异很大，但当可获取的信息仅限于高质量或中等质量的研究时，就有可能得出全国性的估计值：截至2005年，约23.9%的医生在门诊环境中使用EHRs，而5%的医院使用计算机化医嘱录入系统。知识方面存在巨大差距，包括安全网提供者中有关EHR使用的信息，这对旨在加速采用的政策制定构成了严峻挑战。
