Summary

Hospital toothbrushes frequently harbor microbial growth, with nearly half of used brushes showing organisms. This highlights a critical need for enhanced hospital oral care programs to prevent patient exposure to microbes.

Area of Science:

  • Infection Control
  • Hospital-Acquired Infections
  • Microbiology

Background:

  • Oral hygiene is crucial for patient well-being.
  • Microbial contamination of personal items in hospitals poses a potential health risk.

Purpose of the Study:

  • To determine the prevalence of microbial growth on toothbrushes in hospital patient rooms.
  • To assess the risk of microbe exposure from toothbrushes in healthcare settings.

Main Methods:

  • An observational, descriptive study surveyed 5340 patient rooms across 136 hospitals.
  • Toothbrushes were collected from eligible adult patients meeting specific mobility and usage criteria between November 2018 and February 2022.

Main Results:

  • 46% of surveyed patients lacked a toothbrush or had an unused one.
  • Of 1817 used toothbrushes, 48% showed microbial growth.
  • 14% of used toothbrushes were contaminated with three or more organisms.

Conclusions:

  • A significant number of hospital patients lack accessible toothbrushes.
  • Findings underscore the necessity for robust hospital oral care programs.
  • Implementing comprehensive oral hygiene protocols can mitigate microbe exposure risks in patients.
