Rochester General is among many hospitals across the country trying to turn down the volume at night. The initiative started a couple years ago but has been accelerated by research into the effect of noise on healing, and an emphasis under federal health reform on a range of quality measures. As a result, hospitals are paying more attention to patients’ stay as part of their overall care. Rochester General, like others, is educating its medical, housekeeping and transport staff on the importance of piping down.
