Unheard of - sticks are supposed to be disposed of in special containers. If it is the case, you need to contact the “owner” of the facility. If that’s the doc (private practice), you need to let him/her know you’ll need to file a report on him if he won’t return your call. Get the name of the tech - check on reports against his/her licensure.
Jessica, can you give us more details on HOW this happened?
