Interesting article on the possible connection between overworked/burned out nurses and hospital acquired infections: Burned-out nurses linked to more infections in patients – Vitals.
Not clear whether any type of causal relationship was established here (though I doubt it). But nevertheless, this is yet another factor to consider when thinking about the transmission of microbes in hospitals. And this may have a connection to my post here from earlier today: A year old but still worth pondering — is hospital garb a vector for microbes?
