Our hospital makes it a standard question on admission statements for patients about allergies. It asks if they are allergic to food, drugs OR latex, just in case patients do not equate the latex with a general "are you allergic to anything?" question. There are always several boxes of latex-free gloves for the nurses as well as latex-free EKG adhesive pads (I work on a telemetry floor). We also have periodic inservices about latex and things to look for about latex allergies.
I feel our institution covers the subject pretty well. Just a thought!
