Effectiveness and sustainability of the WHO multimodal hand hygiene improvement strategy in the University Hospital Bouaké, Republic of Côte d'Ivoire in the context of the COVID-19 pandemic

Abstract

Abstract Introduction The most frequent adverse events in healthcare are healthcare-associated infections, whose burden is highest in resource-limited settings. In addition, low resource settings often lack Hand Hygiene (HH) knowledge and reliable supply to disinfectant, a necessity emphasized by the past West African Ebola Epidemic and the ongoing COVID-19 pandemic. PASQUALE aims to increase patient safety by introducing the WHO multimodal HH strategy in the University Hospital Bouaké, Côte d’Ivoire. Methods Assessment of HH knowledge, perception and compliance was performed 12 months before, right after the intervention and at a ten months interval using questionnaires for knowledge and perception and direct observation for compliance. The intervention consisted of a HH training and the introduction of local production of alcohol-based hand-rub. In the absence of a control group, the effectiveness of the intervention was assessed by a before-and-after study. Results Baseline knowledge score was 14/25, increased significantly to 17/25 (p < 0.001) upon first and decreased to 13/25 in second follow-up. Compliance showed a significant increase from 12.7% to 36.8% (p < 0.001) in first and remained at 36.4% in second follow-up. Alcohol-based hand-rub production and consumption almost doubled after first confirmed COVID-19 case in Côte d’Ivoire. Conclusion The WHO HH improvement strategy is an effective and pandemic-adaptable method to increase long-term HH compliance. This study emphasizes that the implementation of the strategy to build a robust system is of utmost importance.
