The hospital that I work at only uses signs posted in the room to notify staff to avoid certain arms for no stick or BP. We recently accepted a patient from another major hospital that arrived with an alert bracelet that said no sticks / no bp. It was large and bright and very noticeable. I am curious how other hospitals alert their staff to avoid BP/sticks in certain arms. We have had a few close calls with phlebo, and an actual stick in an AV fistula this past month, so it seems they are not always noticing the signs. I have tried looking for research on what method is the most effective, but so far I haven't found any.
