Potential Pathogens on Neckties: A Risk Assessment Study Among Medical Professionals

This study examines the presence of pathogens on neckties, frequency of tie laundering, and doctors' attitudes towards not wearing ties. Results show common skin flora and pathogens on ties, with no significant association between grade and pathogen presence. Majority of doctors prefer not wearing ties to work. Laundering ties doesn't impact bacterial colonization. Is it time to ditch the tie for good?

  1. Dr. NikhileshTodkari Necktie as a potential vector of infection.

  2. Study carried out to assess • Presence of potential pathogens on necktie • frequency of laundering of ties • attitude of doctors on not wearing a tie • Potential pathogens included • S.aureus • Gram-negative bacteria • VRE

  3. Questionnaire • Grade and speciality • Frequency of laundered necktie • Preference of wearing a tie at work • Incubation • Necktie swabbed • Columbia blood agar used • Incubation at 37 degrees for 48h. METHOD

  4. 1/3 (95/265) of all male doctors took part NCHDs (61%) vs Consultants (13%) RESULTS

  5. Pathogens • Skin flora (CoNS, dipetheroids,micrococci) found on ALL ties. • 10 ties - S.aureus • 7 MRSA • 3 MSSA • 3 ties - mixture of Gram-negative bacilli and S.aureus • VRE not detected on any tie • NO significant association between doctor’s grade and prsence of pathogens.

  6. 55% (52/95) NEVER laundered their tie. Only 15/95 had laundered tie in past 2 months No relationship between laundering of ties and number of pathogens. Majority of doctors 81% would be happy not to wear a tie to work. RESULTS

  7. Presence of skin flora on ties suggests they are handled regularly Laundering of ties has no impact on bacterial colonisation Majority of doctors surveyed had no objection to not wearing a tie. Is it time to hang the tie? CONCLUSION
