Non-Manual Ultraviolet Light Disinfection for Hospital Acquired Infections: A Review of Clinical Effectiveness and Guidelines

Last updated: April 5, 2019
Project Number: RC1091-000
Product Line: Rapid Response
Research Type: Devices and Systems
Report Type: Summary with Critical Appraisal
Result type: Report

Question

  1. What is the clinical effectiveness of non-manual ultraviolet light disinfection for reducing rates of infection and colonisation in healthcare facilities?
  2. What is the comparative clinical effectiveness of non-manual ultraviolet light disinfection methods versus accelerated hydrogen peroxide for reducing rates of infection and colonisation in healthcare facilities?
  3. What are the evidence-based guidelines regarding ultraviolet light disinfection methods for reducing rates of infection and colonisation in healthcare facilities?

Key Message

Low to very low quality evidence from inconsistent and mixed findings precludes a definitive conclusion regarding the clinical effectiveness of non-manual ultraviolet light disinfection in both air and surface for reducing rates of infection and colonization in healthcare facilities. Evidence regarding the comparative clinical effectiveness between non-manual ultraviolet light disinfection methods and accelerated hydrogen peroxide for reducing healthcare-acquired infections was not identified. The Health Quality Ontario guideline recommends against public funding of portable ultraviolet light surface-disinfecting devices for prevention of healthcare-acquired infections.
