Impact of an interventional program on improving compliance of hand hygiene and reducing hospital-acquired infection in the critical care unit

Abstract

Introduction: This study aimed to determine the effect of a hand hygiene (HH) and awareness campaign on knowledge and compliance with HH practices among health-care workers working staff in the main intensive care units and also to evaluate the rates of hospital-acquired infection (HAI) before and after the intervention. Methods: A prospective, interventional, pre-post design was utilized and carried out in three phases: The first stage was a 1-month preintervention stage to develop the foundation of the compliance rate of handwashing; the second stage was the interventional handwashing campaign; the third stage was the postintervention stage to improve the compliance rate of handwashing. Two instruments were used in this study: The HH Knowledge Questionnaire developed by the World Health Organization to assess HH knowledge and the Handwashing Questionnaire developed to evaluate HH washing. Results: HH knowledge has been increased from preintervention (M = 11.84, standard deviation [SD] = 2.41) to postintervention (M = 18.80, SD = 2.93), and the effective compliance with HH practice was as low as 49% in June 2017 to 75% in February 2018. In addition, the HAI rate was dropped from 13.2% in June 2017 to 9% in February 2018. An inverse association was recognized between HH compliance and HAI rates. Conclusions: These results recommend that reasonable approaches can decrease the HAI rate of intensive care units. A nationwide handwashing interventional program can be employed in all hospitals.
