中文摘要 | 加護病房一直是常發生院內感染的單位,而院內血流感染是常見的感染之一。為瞭解南部一醫學中心近來外科加護病房院內原發性血流感染病原菌之變遷,我們收集 1990-1994 年和 1995-1999 年前後各五年間院內原發性血流感染病例資料進行分析。平均院內原發性血流感染發生密度在前後兩時期由 3.80?(個案數/1,000人日)升至 5.06?(p=0.016),病原菌在前後期均以嗜氧性革蘭氏陰性菌為最多。相較於 1990-1994 年之院內原發性血流感染病原菌,在 1995-1999 年 Acinetobacter spp. 及Candida spp. 感染發生密度有明顯增加的情形 (Acinetobacter spp. 前期0.31? vs. 後期 0.91?,p=0.006;Candida spp. 前期 0.31? vs.後期 0.85?,p=0.008);而 Pseudomonas aeruginosa 、 Enterobacter cloacae 和 Klebsiella pneumoniae 發生密度則稍有減少;嗜氧性革蘭氏陽性菌中 Stapnylococcus aureus,Enterococcous spp. 有增加的情形。與美國 NNIS 1990-1999 年一般外科加護病房院內血流感染的報告,以 CoNS (36.1%) 和 Enterococcus spp.(15.3%)兩種革蘭氏陽,性菌為主要病原茵,差異甚大;在本研究 1998-1999 年 Acinetobacter spp. 及Candida spp. 更是成為外科加護病房院內原發性血流感染最主要病原菌,造成這種菌種變遷的原因,有待進一步研究分析。(感控雜誌2001;11:299-310) |
英文摘要 | Most nosocomial infections occur in the intensive care units, and primary nosocomial bloodstream infection is one of the most common patterns of nosocomial infection. To reveal the secular trend of bacteria pathogens of primary nosocomial bloodstream infections in a medical center, we retrospectively collected and analyzed the microbiological data of patients in the surgical intensive care unit of a medical center in southern Taiwan from 1990 to 1999. Results of two consecutive 5-year periods, 1990-1994 and 1995-1999, were compared. The overall incidence density of primary nosocomial bloodstream infection increased from 3.80?(episode/i,000 patient-days) to 5.06?. Aerobic gram-negative bacteria were the most common nosocomial pathogens in both study periods. The frequency of primary bloodstream infections caused by Acinetobacter spp. and Candida spp. increased markedly in the past decade, from 0.31 to 0.91?(p:0.006), and 0.31 to 0.85? (p=0.008), respectively. The frequency of the primary bloodstream infections caused by Psendomonas aeruginosa ' Enterbacter cloacae and Klebsiella pneumoniae decreased and that caused by Staphylococcus aureus ' Enterococcus spp. increased. Moreover, Acinetobacter spp. and Candida spp. turned out to be the most important pathogens in the surgical intensive unit in 1998 and 1999. To eluciate the causes of microbial drift in this unit, further comprehensive epidemiological studies are essential.(Nosooom Infect Control J 2001;11:299-310) |
