This protocol describes the methods for using a novel dry aerosolized hydrogen peroxide (aHP) fogging disinfection technology that provides smart-hospital connectivity, allowing integration within data platforms to provide historical data on equipment usage, verification of aHP dosages, room coverage, disinfection times, and locations to reduce healthcare-associated infections (HAIs).
Overview
This article discusses the limitations of traditional manual and UV disinfection methods in healthcare settings, particularly their inability to thoroughly disinfect hard-to-reach or shadowed areas. It introduces an automated aerosolized hydrogen peroxide (aHP) dry fogging technology as a novel solution, highlighting its potential to improve whole-room disinfection, reduce healthcare-associated infections (HAIs), and provide robust data tracking for quality assurance.
Key Study Components
Area of Science
- Infection control
- Environmental disinfection
- Healthcare epidemiology
Background
- Traditional disinfection methods often leave gaps, especially in shadowed or hard-to-reach areas.
- Incomplete disinfection increases the risk of HAIs.
- Manual methods pose exposure risks to healthcare personnel and are labor-intensive.
- There is a need for more effective, efficient, and auditable disinfection technologies.
Purpose of Study
- To outline the protocol for using an automated aHP dry fogging system in healthcare environments.
- To demonstrate the system's efficacy in achieving comprehensive room disinfection.
- To assess the impact of this technology on the transmission and costs associated with carbapenem-resistant Acinetobacter baumannii (CRAB).
Methods Used
- Deployment of an automated aHP dry fogging system that disperses micron-sized hydrogen peroxide droplets throughout entire rooms.
- Integration of the system with data platforms for real-time tracking and auditing of disinfection events.
- Evaluation of disinfection coverage and efficacy, including historical data analysis and verification of aHP dosages and room coverage.
- Assessment of the impact on CRAB transmission rates and associated costs.
Main Results
- The aHP dry fogging system achieved uniform coverage of all room surfaces, including hard-to-reach areas.
- Data integration enabled quality assurance and auditable records of disinfection events.
- Use of the system as part of a carbapenem-resistant organism (CRO) mitigation strategy led to a statistically significant reduction in CRAB transmission rates compared to expected rates.
- Implementation resulted in decreased direct costs and improved productivity related to infection control.
Conclusions
- Automated aHP dry fogging technology offers superior whole-room disinfection compared to traditional methods.
- Integration with data platforms enhances quality assurance and compliance tracking.
- This approach can significantly reduce the transmission of multidrug-resistant organisms and associated healthcare costs.
