Laboratory personnel jewelry use, including rings, watches, and bracelets, correlated with pathogenic microorganisms. Implementing a no-jewelry policy significantly improved hand hygiene compliance and reduced contamination risks.

Area of Science:

  • Microbiology
  • Occupational Health
  • Infection Control

Background:

  • Hand hygiene is crucial for preventing pathogen transmission in laboratory settings.
  • Jewelry worn by laboratory personnel can harbor microorganisms and impede effective handwashing.

Purpose of the Study:

  • To assess laboratory personnel's adherence to hand hygiene practices, specifically concerning jewelry.
  • To determine the association between jewelry use and microbial contamination on hands.
  • To evaluate the impact of a no-jewelry policy intervention.

Main Methods:

  • Observational study measuring compliance with hand hygiene components.
  • Microbial sampling of hands of laboratory personnel.
  • Implementation of a no-jewelry policy followed by post-intervention assessment.

Main Results:

  • While overall end-of-duty compliance was high, significant percentages of personnel wore rings (36.7%), watches (46.9%), and bracelets (6.1%).
  • Pathogenic microorganisms were exclusively detected on the hands of personnel wearing jewelry.
  • The no-jewelry policy intervention led to sustained improvements in compliance.

Conclusions:

  • Jewelry is a significant factor contributing to microbial contamination on the hands of laboratory personnel.
  • Effective hand hygiene strategies in laboratories must address and restrict the wearing of jewelry.
  • Interventions to enhance hand hygiene compliance should encompass laboratory personnel, not solely healthcare workers.
