In my unit (trauma ICU) patients get bed baths twice a day - once by day shift and again by night shift. The nurses do this as an opportunity to check the patients for pressure sores and because they say it is comforting to the patient. I have no problem doing this assuming time permits, but wouldn't excessive bathing make patients prone to skin breakdown, dry out their skin, and reduce the skin's normal flora? I would always bath a patient if they are really dirty and when they are incontinent, but how often should they get a full bath? Can anyone help by recommending research articles on this topic? I want to use evidence-based practice to determine the correct thing to do.
