A recent recommendation in Mexico is that all health secretary and gubernamental workers must lose their ties. This will be obviously a tragedy for the economic of the companies that sell them and the bow tie might be back (which I personally don´t dislike). I tried to search evidence on the topic, specifically clinical data that could be evidence for or against the use of ties with clinical outcomes. I did not find anything on Pubmed using the search strategy "(white coat OR tie) AND infection" Any suggestions? evidence? even if it is indirect evidence -- Carlos A.
