A clinical study on behavioral change theory in improving hand hygiene compliance of medical staff

Abstract

Objective To explore the effect of behavioral change theory in improving hand hygiene knowledge and hand hygiene compliance of medical staff. Methods 180 cases of medical staff were applicated of behavioral change theory for hand hygiene knowledge and hand-washing compliance from January 2016 to December 2016. The health knowledge and hand hygiene compliance of medical staff before and after implementation were compared. Results The awareness rates of medical staff on the 6-step washing method, hand washing time, hand washing times, hand washing materials, hand washing range and other knowledge after implementation were 98.89%, 97.77%, 96.67%, 97.22%, 95.55%, higher than those before implementation (82.22%, 83.33%, 78.89%, 78.89%, 77.22%) (P<0.05). The compliance rate of hand washing, accuracy rate of hand washing, hand hygiene qualification rate, patient satisfaction rate after implementation were 95.55%, 97.78%, 98.88%, 97.00%, higher than those before implementation (86.11%, 82.78%, 82.22%, 75.00%) (P<0.05). The detection rate of hand bacterial colony after implementation was lower than that before implementation (1.11% vs.17.78%, P<0.05). Conclusion The behavioral change theory can improve the awareness rate of hand hygiene knowledge, improve the compliance of hand-washing and hand-washing hygiene pass rate of medical staff, and helps to prevent the occurrence of iatrogenic infection.
