Background: The most important factors in the prevention of nosocomial infections are considering the infection control standards with short term and continuing education for nurses. This study was conducted to determine the effect of education on impediments of adherence of intensive care nurses from infection control standards. 

  Methods: A randomized clinical trial was carried out with two group design pre and post-test control group including 30 nurses of intensive care units of hospitals of Hamadan University of Medical Sciences by theoretical and clionical lectures, focus group discussion and practical workshops in the intensive care units. The research tool was a researcher asking the nurses about impediments of adherence to infection control standards by measuring with a scale from 0 to 9 . The r eliability and validity of the questionnaire was determined by expert panels, the test - retest (r = 0.82) and Cronbach Alpha (0. 79). The questionnaires were completed by nurses in both the test and control groups before and after education. Statistical analysis was done by Friedman, Kruskal-Wallis and Man-Witni test.

  Result: There were not significant different among participants in two groups (p<0.05). The mean scores of nurses' perceptions about adherence impediments in test and control groups at baseline were not statistically significant. But 14 and 30 days after education, the mean increased in nurses' perception about adherence impediments in test group (p<0.05).

  Conclusion: The education about infection control standards had a positive impact on nurses’ perception about adherence impediments. So the training of infection control standards is recommended short term and continiously .
