Light-guided nudging and data-driven performance feedback improve hand hygiene compliance among nurses and doctors

Area of Science:

• Healthcare Quality Improvement
• Infection Prevention and Control
• Health Informatics

Background:

• Hand hygiene compliance (HHC) is crucial for preventing infections in healthcare settings.
• Evidence-based practices are needed to enhance HHC among healthcare workers.
• A multimodal strategy was investigated to improve HHC.

Purpose of the Study:

• To evaluate the impact of a multimodal strategy on hand hygiene compliance (HHC) among healthcare workers.
• To assess the effectiveness of an automated monitoring system with light-guided nudging and performance feedback.

Main Methods:

• A 14-month prospective, observational study was conducted in a surgical ward.
• An automated monitoring system tracked hand hygiene opportunities and alcohol-based hand rubbing events.
• Health care worker HHC was compared before and during the implementation of the multimodal strategy using Student's t test.

Main Results:

• Doctors showed significant increases in HHC in both patient rooms (16% to 42%) and working rooms (24% to 78%).
• Nurses demonstrated significant HHC improvements in patient rooms (27% to 43%) and working rooms (39% to 64%).
• Individual performance feedback further enhanced nurses' HHC compared to group feedback.

Conclusions:

• A multimodal strategy, including light-guided nudging and data-driven feedback, significantly improves HHC in doctors and nurses.
• Automated hand hygiene systems can be effectively utilized to enhance compliance.
• These findings support the integration of technology in infection control practices.
