In a
commentary published alongside the study, Tara Palmore, MD, notes the need for additional research on the topic: «Hospitals tend to have large, complex waterworks with low - flow areas that
produce stagnation and biofilm formation; hot and cold water temperatures that are not well regulated may be ideal for bacterial growth... the work of Cristina et al. is
valuable in quantifying the frequency, magnitude, and location of the potential hazard to patients from hospital water in their facilities.
