title: [Prevention of ventilator-associated pneumonia: a comparison of level of knowledge in three critical care units].
abstract: OBJECTIVE
  To determine the level of knowledge of the prevention of ventilator-associated pneumonia guidelines of nurses working in three intensive care units (ICU) in 3 university hospitals in a Spanish region, and evaluate the relationship between this level of knowledge and years worked in the ICU.
  
  
  METHODS
  A descriptive, prospective, cross-sectional, multicentre study was conducted using a validated and reliable questionnaire, made up by 9 questions with closed answers drawn from the EVIDENCE study. A total of 98 questionnaires were collected from ICU nurses of the three university hospitals (A, B, and C) from January to April 2014. The sample from hospital A responded the most, in contrast with the sample from hospital B, which was the one with the less participation. The Pearson correlation was calculated in order to determine the relationship between nurse years worked in ICU and level of knowledge.
  
  
  RESULTS
  Hospital A obtained in the best mean score in the questionnaire, 6.33 (SD 1.4) points, followed by hospital C with 6.21 (SD 1.4), and finally, the hospital B with 6.06 (SD 1.5) points. A p=.08 was obtained on relating years worked with the level of knowledge.
  
  
  CONCLUSIONS
  The results showed a high level of knowledge compared other studies. There was a tendency between the years worked in the unit and the level of knowledge in ventilator-associated pneumonia prevention.
