| Summary: | 碩士 === 輔英科技大學 === 護理系碩士班 === 101 === The advancement of medical technology has made people living longer than ever. In Taiwan, every one in ten is elderly currently. The most risk factor of bloodstream infections in the intensive care unit (ICU) is aging, which can increase the rate of mortality and the length of hospitalization. The objective of this research was to understand the characteristics and risk factors of bloodstream infections in the intensive care unit among elderly as well as the types of bacteria.
This retrospective research collected patients who were above age of 65 and stayed in a medical intensive care unit during the year 2006 to 2011. The infected group and the control group were both 132 cases by matching their gender, age, and intensive unit. The results showed that risks of factors associated with bloodstream infections of the followings are: central venous catheter device (OR, 33.315; 95％CI, 1.203~922.610); other infections (OR, 9.440; 95％CI, 1.075~82.897); re-on central venous catheter device (OR, 6.278; 95％CI, 2.054~19.190); Hemodialysis (OR, 6.010; 95％CI, 1.516~23.833); receiving a blood transfusion (OR,3.171; 95％CI, 1.161~8.659); length of ICU stay (OR, 1.325; 95％CI, 1.196~1.468). The above six variables were statistical significance. In addition, the most common isolates areCandida albicans (10.6%) ,Acinetobacter baumannii(9.9%) ,Staphylococcus aureus (9.9%) ,Klebsiella pneumonia(9.1%) .
Expect this research can be used in the clinical reduction obtained health- care -associated bloodstream infections, provide clinical practitioners and educators in the elderly healthcare-associated bloodstream infection level of understanding of risk factors, and intervention to prevent healthcare-associated bloodstream infections earlier.
