일개 요양병원 입원환자들의 요로감염과 거동불능과의 상관관계

Abstract

Background

Recently, The number of nursing hospitals has increased in South Korea. Urinary tract infections are one of the most common diseases dealt in nursing hospitals. This UTI is usually common in the elderly and has a great discomfort in the quality of the elderly's life. But domestic studies about the UTI in the elderly are rare. Thus, this study was conducted in a nursing hospital to find out epidemiologic characteristics of the UTI in elderly.Method This study was performed in 128 subjects from December 1, 2010 to May 31, 2011 residing in a nursing hospital in G-J City. First, history of UTI symptoms and Physical examination was taken, and collection of urine sample by midstream clean-catch technique or catheterization was performed Next, microscopic urine analysis and urine culture was done three times by every 8weeks.Result 128 patients(male:25, female:103) were observed. The ratio of males to females was 1:4.1. mean age of patients was 80.9(65∼104).

The overall prevalence of UTI in patients was 53.1%(68/128) : 32%(8/25) in males and 58.3% (60/103) in females. The prevalence of UTI in the immobile subject was 67.4% (60/89) and That of mobile subject was 20.5%(8/39). The most common pathogen were Proteus mirabilis(37.4%). followed by E.coli(29.9%), Enterococcus faecalis(7.5%), Pseudomonas aeruginosa(5.6%) in the order.

Conclusion The prevalence of UTI in the elderly residing in a nursing hospital was higher than those of the elderly residing in a community. In the elderly over 65 year, Immobility is considered as a risk factor of UTI. Thus, we can expect improvement in the quality of life when UTI is well treated in the patients at the nursing hospital by early diagnosis and adequate antibiotics therapy. More efforts should be taken in the elderly for protection of diseases lead to immobility.
