Background: Adequate hand hygiene is considered the most effective measure to reduce transmission of nosocomial pathogens.
Aims: To determine the effectiveness of infection control intervention to improve compliance with hand hygiene in the Emergency Department, Al-Leith General Hospital, Saudi Arabia, and evaluate bacterial load on hands as a possible indicator of improvement.
Methods: The study consisted of 3 phases: Phase I, measurement of basal hand hygiene compliance level; Phase II, multimodal hand hygiene educational programme was initiated; and Phase III, hand hygiene compliance level was measured again. Data were collected by direct observation of healthcare workers in the emergency department between October 2016 and March 2017, using the standardized World Health Organization method for direct observation, "Five Moments for Hand Hygiene". The intervention comprised health education sessions using direct personal contact. Hands of healthcare workers were sampled during Phases I and III by sterile bag method, and bacterial load was determined.
Results: A total of 1374 opportunities for hand hygiene were observed during the triphase study. Implementation of the interventional hand hygiene educational programme significantly improved compliance with hand hygiene guidelines from 30.7% to 45.5% (P < 0.01). Log10 bacterial load per hand dropped from 4.97 (standard deviation = 0.32) to 4.57 (0.47) (P < 0.05).
Conclusions: Hand hygiene educational programmes were effective in improving compliance in the emergency department, and bacterial load on hands of healthcare workers could be used as an indicator of improvement in hand hygiene compliance. |
