Evolution of adherence to hand hygiene in health care professionals in a third-level hospital in relation to the sars-cov-2 pandemic

Abstract

Introduction. Proper hand hygiene is the main measure in the prevention and control of infection associated with healthcare. It describes how the pandemic period of 2020 has influenced the evolution of the degree of compliance with hand hygiene practices in health professionals at the Hospital Universitario Insular de Gran Canaria with respect to previous years. Methods. Descriptive cross-sectional study of direct observation on compliance with the five moments of hand hygiene in the 2018-2020 period. Adherence is described with the frequency distribution of the different moments in which it was indicated. Results. Total adherence has increased from 42.5% in 2018, to 47.6% in 2019, and 59.2% in 2020 (p <0.05). Total adherence was greater in the moments after contact with the patient (67%) than in the moments before contact (48%). The area with the highest adherence was dialysis (83%). There is a greater adherence in open areas than in hospitalization areas (65% vs 56%). Higher adherence was determined in physicians (73%) and nurses (74%), than in nursing assistants (50%) (p <0.05). Conclusions. In 2020 there was an increase in adherence to hand hygiene compared to previous years. A higher per-centage of adherence was determined in physicians and nurses than in nursing assistants. We consider that the current SARS-CoV-2 pandemic has played a relevant role in this increase in adherence.
