title: Hand hygiene practices in a dental teaching center: Measures and improve.
abstract: OBJECTIVE
  To measure the compliance and the quality of HH practices and the knowledge of the healthcare workers' of the university dental care center.
  
  
  METHODS
  All educators and students present were eligible for inclusion in the study. Each healthcare professional was observed in care situation over a period of 30 min. The knowledge, attitudes and opinions were collected through a questionnaire.
  
  
  RESULTS
  Number of healthcare professionals included was 190 (64.4%). Study group consisted of 151 students (74.4%) and 39 educators (42.4%). Out of a total number of expected disinfection of hands (993), 396 were made (39.9%). Educators had a higher compliance rates than students (63.7-35.8%, P = 10(-9)). Large differences were found between care situations (compliance higher before the first care to a patient and lower during installation of patient in dental X-ray area or at exit of dental X-ray area). Concerning hand rubbing (HR), 36.6% were performed correctly, and the main error was all steps of HR not observed (54.4%), and shorter duration (46.7%). The observance and the quality of HR were associated with better knowledge.
  
  
  CONCLUSIONS
  This data suggests areas of improvement: (1) A comprehensive intervention including care organization/clinic ergonomics/planning/anticipation of materials needed for care; (2) the development of HH education program should include the educators, since the behavior of students is strongly influenced and formed by their mentor's attitude and behaviors.
