title: Control method exploration of nosocomial bloodstream infection and its effect evaluation.
abstract: BACKGROUND
  Currently, slightly more than 50% of bloodstream infections (BSIs) are hospital acquired. When these infections occur in patients in intensive care units, they are associated with a high mortality rate, additional hospital days and excess hospital costs. Because of multifactor of nosocomial BSIs, measurements of control nosocomial BSIs are wide variety and lead to some confusion in practice. The aim of this study was to explore special way in accordance with self-hospital base on common principle.
  
  
  METHODS
  In one ward of the Intensive Care Unit, Peking Union Medical College Hospital, at first, we divided the all operation about bloodstream way into three sections used as keypoints. By surveying keypoints respectively, some operation faults of blood way were discovered. For decreasing the mobidity of nosocomial BSIs, some intervention measurements were executed. The rate of nosocomial BSIs was analyzed by chi-square test.
  
  
  RESULTS
  According to the statistics from January to June, we received and cured 618 patients in total; among them, there were 13 cases of nosocomial BSI and the average occurrence was 2.3 cases/month. After intervention measurements from July to December 2011, we received and cured 639 patients in total with seven cases of nosocomial BSI, and the average occurrence was 1.2 cases/month (P < 0.05). From January to April 2012, no nosocomial BSI occurred in the investigated ward.
  
  
  CONCLUSIONS
  Removing the operation faults of bloodstream way might decrease the nosocomial BSI rapidly and efficiently by utilizing a key point survey.
