This report describes ambulatory care visits to hospital outpatient departments in the United States. Statistics are presented on selected hospital, clinic, patient, and visit characteristics.
The data presented in this report were collected from the 1998 National Hospital Ambulatory Medical Care Survey (NHAMCS). NHAMCS is part of the ambulatory care component of the National Health Care Survey that measures health care utilization across various types of providers. NHAMCS is a national probability sample survey of visits to hospital outpatient and emergency departments of non-Federal, short-stay, and general hospitals in the United States. Sample data are weighted to produce annual estimates.
During 1998, an estimated 75.4 million visits were made to hospital outpatient departments in the United States, an overall rate of 28.0 per 100 persons. Visit rates did not vary by age except in a comparison of the 15-24 year old group with the 75 years and over age group. Black persons had higher rates of visits than white persons as did women compared with men. Of all visits made to hospital outpatient departments in 1998, 33.8 percent and 25.9 percent, respectively, listed private insurance and Medicaid as the primary expected source of payment, and 21.9 percent were made by patients belonging to a health maintenance organization. There were an estimated 7.1 million injury-related outpatient department visits during 1998.

本报告中的数据来自1998年全国医院门诊医疗护理调查（NHAMCS）。NHAMCS是全国医疗护理调查中门诊护理部分的一部分，该调查衡量各类医疗服务提供者的医疗护理利用情况。NHAMCS是对美国非联邦、短期停留和综合医院的门诊和急诊科就诊情况进行的全国概率抽样调查。样本数据经过加权以得出年度估计值。
1998年期间，美国医院门诊部门的就诊估计有7540万次，总体就诊率为每100人28.0次。除了将15 - 24岁年龄组与75岁及以上年龄组进行比较外，就诊率在各年龄组中并无差异。黑人的就诊率高于白人，女性的就诊率高于男性。在1998年所有医院门诊部门的就诊中，分别有33.8%和25.9%将私人保险和医疗补助列为主要预期支付来源，21.9%的就诊是由健康维护组织的患者进行的。1998年期间，估计有710万次与伤害相关的门诊就诊。
