Abstract
Most nosocomial infections are thought to be transmitted by the hands of health care workers. The aim of this work was to assess the knowledge, attitude and practice of hand washing among health care workers (HCW) in Ain-Shams University hospitals and to investigate the presence of the necessary facilities and supplies required for hand washing (HW) in ten wards. A cross- sectional descriptive and observational study was conducted for six months from June till November 2006. Observation of the HCW for hand washing practice was done at any opportunity of contact with the patients in the different wards by members of the infection control team. Knowledge & attitude of HCW towards hand hygiene was done through self-administered questionnaire to HCW in 10 different departments. The total opportunities observed were 2189 opportunities. Doctors showed a signifi- cantly higher compliance (37.5%) than other groups of HCW (P = 0.000), however only 11.6% of the opportunities observed for doctors were done appropriately. The most common type of HW practiced among HCW was the routine HW (64.2%) and the least was the antiseptic HW (3.9%). Having a short contact time and improper drying (23.2%) were the most common errors that lead to inappropriate HW. Most of the wards had available sinks (80%) but none of them had available paper towels. The mean knowledge score was higher in nurses compared to doc- tors (42.6 ± 11.7 versus 39.1 ± 10.5). Most of the nurses (97.3%) believe that administrative orders and continuous observation can improve hand washing practices. Implementation of mul- tifaceted interventional behavioral hand hygiene program with continuous monitoring and performance feedback, increasing the supplies necessary for HW and institutional support are impor- tant for improving the compliance of hand hygiene guidelines.
