I work at an endoscopy center (and a freestanding surgery center). A few times, we've had patients lie to us about how they are getting home, and they've ended up returning to their cars, and driving home. Of course we find this out too late to get a license number. Once, myself and another nurse walked around the hospital across the street to see if we could locate the car, but the patient had already left in it, after giving us vague directions as to where he had parked.
I am responsible for my patients' safety, and ultimately that of the general public, as I mostly work in recovery/PACU.
Any ideas on how we can combat this problem?
