The North Carolina legislature slipped this in several years ago. Medics are often called to assist LEO at their stations to administer blood draws. The Blood draw kits have all required materials and LEO assumes the chain of custody. For rural areas it is a big help to the Troopers and Deputies. In municipalities it becomes a hassle every Friday and Saturday night due to the frequency of impaired drivers and the LEO staffing constraints. For LEO to travel to the hospital for a blood draw removes them from their coverage area which impacts community policing, etc. One may argue that it delays medical response as well. In NC if a patient refuses to allow the procedure to occur (patient refusal documentation) the patient automatically loses their operators permit for a year. So in a way its a win-win situation. Some patients are less than cooperative and that can become an issue. Perhaps a consult with North Carolinas EMS leaders would help in making a informed decision.
