This report presents information on the adoption of electronic medical records (EMRs) by office-based physicians in 2007. Percentages of medical practices and physicians within practices using EMR systems are presented by selected physician and practice characteristics.
Data from the physician induction interviews of the 2007 National Ambulatory Medical Care Survey (NAMCS) are presented. NAMCS is based upon a national probability sample of nonfederal office-based physicians who saw patients in an office setting. Sample data were weighted to produce national estimates of office-based physician characteristics and their practices.
In 2007, 34.8 percent of office-based physicians reported using any EMR (all electronic or partially electronic medical record) system, which represented a 19.2 percent increase since 2006 and a 91.2 percent increase since 2001. Starting in 2005, NAMCS included additional questions about features of electronic record systems making it possible to categorize systems as basic or fully functional using similar definitions developed by health information technology (HIT) experts. Fully functional systems are a subset of basic systems. Some systems do not meet the requirements. In 2007, 11.8 percent of physicians had systems meeting the criteria of basic systems (95% CI: 9.6-13.9), unchanged from 2006 (10.5 percent). The percentage of office-based physicians with systems meeting the definition of fully functional (3.8 percent, 95% CI: 2.6-5.0) was similar to the 2006 percentage (3.1 percent). Physicians in practices with 11 or more physicians were most likely to use any EMR system (74.3 percent), whereas physicians in solo practice were least likely to use EMRs (20.6 percent). EMR use was higher among physicians in multi-specialty practices (52.5 percent) than in solo or single-specialty practices (30.3 percent). EMR use was inversely associated with physician age. If those without EMR systems in 2007 with definite plans to install one actually do so, 53.6 percent of physicians will have some type of an EMR system in 2010.
本报告提供了2007年门诊医生采用电子病历（EMR）的相关信息。使用EMR系统的医疗执业机构及机构内医生的比例按选定的医生和执业机构特征列出。
呈现的是2007年国家门诊医疗护理调查（NAMCS）中医生入职访谈的数据。NAMCS基于在门诊环境中接待患者的非联邦门诊医生的全国概率样本。对样本数据进行加权处理，以得出全国门诊医生特征及其执业情况的估计值。
2007年，34.8%的门诊医生报告使用了任何EMR（全电子或部分电子病历）系统，这比2006年增长了19.2%，比2001年增长了91.2%。从2005年开始，NAMCS纳入了有关电子记录系统功能的更多问题，从而能够使用健康信息技术（HIT）专家制定的类似定义将系统分类为基本系统或全功能系统。全功能系统是基本系统的一个子集。有些系统不符合要求。2007年，11.8%的医生拥有符合基本系统标准的系统（95%置信区间：9.6 - 13.9），与2006年（10.5%）持平。符合全功能定义的门诊医生比例（3.8%，95%置信区间：2.6 - 5.0）与2006年的比例（3.1%）相似。在拥有11名或更多医生的执业机构中，医生使用任何EMR系统的可能性最大（74.3%），而个体执业医生使用EMR的可能性最小（20.6%）。多专科执业医生中EMR的使用率（52.5%）高于个体或单专科执业医生（30.3%）。EMR的使用与医生年龄呈负相关。如果2007年那些明确计划安装EMR系统但尚未安装的医生真的这样做了，那么到2010年，53.6%的医生将拥有某种类型的EMR系统。
