Impact of COVID-19 on environmental services workers in healthcare settings: a scoping review
TL;DR: In this paper , the impact of the COVID-19 pandemic on environmental services workers employed in healthcare settings was examined and a search strategy was developed, in consultation with a medical information specialist, employing various combinations of the keywords [(environmental services worker OR health attendant OR housekeeping) AND (COVID OR coronavirus OR pandemic OR epidemic)].
