Once. We were taking a patient from the nursing home to the ER.
The patient listed off to the side due to a previous stroke and had a chief complaint of diarrhea, abdominal pain, and a fever. We had trouble keeping upright, despite pillows and the like she still wanted to fall off the stretcher.
The closest ER was ORMC, which is a very busy Level I trauma center. While we were there they had two trauma alerts come in, one from flight, one by ground, so needless to say it was awhile before we got a room and held the wall for wel over an hour. I hate to stand around with gloves on, so I would take mine off, and re glove when I had to adjust the patient on the stretcher or something or another.
One time she was about to fall right off the edge so I grabbed her quick, bare handed, and we hauled her up back on the stretcher just as the triage nurse told us which room we could put her in, so I grabbed some foamy spray and off we went, re gloved, sheeted her over. After giving report to the nurse, he just shrugged his shoulders "Oh! She has C-Diff!".
I scrubbed my hands in the sink for about fifteen minutes after that and have not touched a patient bare handed since.
