This report describes ambulatory care visits made to physician offices in the United States. Statistics are presented on selected characteristics of the physician's practice, the patient, and the visit.
The data presented in this report were collected in the 2007 National Ambulatory Medical Care Survey (NAMCS), a national probability sample survey of visits to nonfederal office-based physicians in the United States. Sample data are weighted to produce annual national estimates of physician visits.
During 2007, an estimated 994.3 million visits were made to physician offices in the United States, an overall rate of 335.6 visits per 100 persons. About one-third of office visits, 34.9 percent, were made to practices with all or partial electronic medical records systems, while 85.1 percent of the visits were made to practices with all or partial electronic submission of claims. From 1997 to 2007, the percentage of visits to physicians who were solo practitioners decreased 21 percent. During the same period, visits to physicians who were part of a group practice with 6-10 physicians increased 46 percent. There were an estimated 106.5 million injury- or poisoning-related office visits in 2007, representing 10.7 percent of all visits. Medications were ordered, supplied, or administered at 727.7 million office visits, accounting for 73.2 percent of all office visits. In 2007, about 2.3 billion drugs were ordered, supplied, or administered, resulting in an average of 226.3 drug mentions per 100 visits.
本报告描述了美国门诊患者到医生办公室就诊的情况。报告呈现了有关医生执业、患者及就诊的选定特征的统计数据。
本报告中的数据来自2007年全国门诊医疗调查（NAMCS），这是一项对美国非联邦门诊医生就诊情况的全国概率抽样调查。样本数据经过加权处理，以得出全国年度医生就诊估计数。
2007年期间，美国估计有9.943亿人次到医生办公室就诊，总体就诊率为每100人335.6次就诊。约三分之一（34.9%）的门诊就诊是到使用全部或部分电子病历系统的医疗机构，而85.1%的就诊是到采用全部或部分电子索赔提交方式的医疗机构。从1997年到2007年，到个体执业医生处就诊的比例下降了21%。在同一时期，到由6至10名医生组成的联合诊所就诊的人数增加了46%。2007年估计有1.065亿人次因受伤或中毒到医生办公室就诊，占所有就诊人次的10.7%。在7.277亿人次的门诊就诊中开具、提供或使用了药物，占所有门诊就诊人次的73.2%。2007年，大约开出、提供或使用了23亿剂药物，平均每100次就诊提及226.3种药物。
