Physicians often underestimate how long they use medical white coats, leading to potential hygiene issues. The study found actual use averaged 20 days per coat, highlighting a need for better education on hospital hygiene practices.
Area of Science:
- Medical Microbiology
- Hospital Hygiene
- Infection Control
Background:
- Medical white coat contamination increases with duration of use.
- No current guidelines exist for the frequency of medical white coat changes.
- Understanding white coat turnover is crucial for hospital hygiene.
Purpose of the Study:
- To examine the turnover rate of medical white coats in a university hospital setting.
- To identify factors influencing the duration of medical white coat use.
Main Methods:
- Retrospective analysis of 826 physicians' white coat turnover.
- Utilized hospital laundry database and electronic surveys for data collection.
- Assessed duration of medical white coat use.
Main Results:
- Significant discrepancy noted between laundry data and physician self-reported use.
- Median factual coat use was 20 days (2 coats/month), underestimated by physicians.
- Factors for extended use included perceived insufficient turnover, belief daily change is unnecessary, non-medical specialty, and visible stains.
Conclusions:
- Physicians significantly underestimate medical white coat usage duration.
- Medical white coat use duration should be shortened.
- Integrating education on white coat hygiene into medical training is recommended to improve hospital infection control practices.
