Abstract

BACKGROUND

The Department of Veterans Affairs (VA) is the largest single provider of long-term care in the United States. The prevalence of nursing home-associated infections (NHAIs) among residents of VA nursing home care units (NHCUs) is not known.

METHODS

A Web-based point prevalence survey of NHAIs using modified Centers for Disease Control and Prevention definitions for health care-associated infections was conducted in the VA's 133 NHCUs on November 9, 2005.

RESULTS

From a total population of 11,475 NHCU residents, 591 had at least 1 NHAI for a point prevalence rate of 5.2%. Urinary tract infection, asymptomatic bacteriuria, pneumonia, skin infection, gastroenteritis, and soft tissue infection were most prevalent, constituting 72% of all NHAIs. A total of 2817 residents (24.5%) had 1 or more indwelling device. Of these 2817 residents with an indwelling device(s), 309 (11.0%) had 1 or more NHAI. In contrast, the prevalence of NHAIs in residents without an indwelling device was 3.3%. Indwelling urinary catheter, percutaneous gastrostomy tube, intravenous peripheral line, peripherally inserted central catheter, and suprapubic urinary catheter were most common, accounting for 79.3% of all devices used.

CONCLUSION

There are effective infection surveillance and control programs in VA NHCUs with a point prevalence of NHAIs of 5.2%.

摘要

背景

美国退伍军人事务部（VA）是美国最大的长期护理单一提供者。VA疗养院护理单元（NHCUs）居民中与疗养院相关感染（NHAIs）的患病率尚不清楚。

方法

2005年11月9日，在VA的133个NHCUs中，使用美国疾病控制与预防中心修改后的医疗保健相关感染定义，对NHAIs进行了基于网络的现患率调查。

结果

在11475名NHCU居民中，591人至少患有一种NHAI，现患率为5.2%。尿路感染、无症状菌尿、肺炎、皮肤感染、肠胃炎和软组织感染最为常见，占所有NHAIs的72%。共有2817名居民（24.5%）有1个或更多留置装置。在这2817名有留置装置的居民中，309人（11.0%）患有一种或更多NHAI。相比之下，没有留置装置的居民中NHAIs的患病率为3.3%。留置导尿管、经皮胃造瘘管、外周静脉导管、经外周静脉穿刺中心静脉导管和耻骨上导尿管最为常见，占所有使用装置的79.3%。
