Answer: Excellent question. You are not alone in your interest for patient follow up. The bottom line is that the Base Hospital is unable to implement a system such as you describe: we wish we could!
Not only are paramedics not privy to this type of information which could be valuable on a number of levels (research, education, closure for the provider following traumatic cases), but many other health care practitioners are unable to access this information (nurses, emergency physicians) due to privacy legislation.
Unless you are actively involved the “circle of care” and access to patient information is necessary at that moment in time in order to directly influence the management of that patient, we are prevented from accessing patient information.
