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. MATERIALS AND 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. CONCLUSION: 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.
