This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 2004 and selected trend data. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Average lengths of stay are presented for all discharges and for selected diagnostic categories by age and by sex.
The estimates are based on medical abstract data collected through the 2004 National Hospital Discharge Survey (NHDS). The survey has been conducted annually by the Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS) since 1965. Diagnoses and procedures presented are coded using the International Classification of Diseases, 9th Revision, Clinical Modification, or ICD-9-CM.
Trends in the utilization of non-Federal short-stay hospitals show that the rate of hospitalization of the elderly (those 65 years and over) increased 24 percent from 1970 through 2004 despite a decrease in the 1980s. The rates for the other age groups declined overall. In 2004, those 65 years and over comprised 12 percent of the U.S. population, 38 percent of all hospital discharges, and used 44 percent of all inpatient days of care. In 2004, there were an estimated 34.9 million hospital discharges, excluding newborn infants. The average length of stay was 4.8 days for all inpatients and 5.6 days for the elderly. Almost one-half of hospital stays for heart disease had a first-listed discharge diagnosis of either congestive heart failure (25 percent) or coronary atherosclerosis (24 percent). There were 45 million procedures performed on inpatients during 2004. From 1995 through 2004, for those 65 years and over, the rate of hip replacements increased 38 percent, and the rate of knee replacements increased 70 percent. One-quarter of all procedures performed on females were obstetrical. Almost one-quarter of all procedures performed on males were cardiovascular.
本报告呈现了2004年美国非联邦短期住院医院使用情况的全国性估计数据以及部分趋势数据。出院人数、诊断和手术的数量及比率按年龄和性别列出。所有出院患者以及按年龄和性别划分的特定诊断类别的平均住院时长也有呈现。
这些估计数据基于通过2004年全国医院出院调查（NHDS）收集的医学摘要数据。自1965年以来，疾病控制与预防中心的国家卫生统计中心（NCHS）每年都会开展此项调查。所呈现的诊断和手术均使用《国际疾病分类》第九版临床修订本（ICD - 9 - CM）进行编码。
非联邦短期住院医院使用情况的趋势表明，尽管在20世纪80年代有所下降，但从1970年到2004年，老年人（65岁及以上）的住院率增长了24%。其他年龄组的住院率总体呈下降趋势。2004年，65岁及以上人群占美国人口的12%，占所有医院出院人数的38%，并占用了所有住院护理天数的44%。2004年，估计有3490万例医院出院病例（不包括新生儿）。所有住院患者的平均住院时长为4.8天，老年人为5.6天。几乎一半的心脏病住院病例的首要出院诊断为充血性心力衰竭（25%）或冠状动脉粥样硬化（24%）。2004年住院患者共进行了4500万例手术。从1995年到2004年，65岁及以上人群中，髋关节置换率增长了38%，膝关节置换率增长了70%。女性接受的所有手术中有四分之一是产科手术。男性接受的所有手术中有近四分之一是心血管手术。
