People can bemoan defensive medicine and its costs all they want. But, if you’ve been sued, you won’t care. You’ll order any test to protect yourself. Claiming that you followed a guideline from a journal, no matter how well researched it was, will likely be worthless the one time a stroke was missed. It’s easy for a plaintiff’s attorney to find someone to say you fell below the standard of care for doing so.
For an example of where this stands, here’s something from personal experience: One of my patients went to the emergency department for recrudescence of an old left hemiparesis, likely caused by a urinary tract infection. This wasn’t the first time it had happened. A head CT was stable while a urine analysis was abnormal. Because of my schedule, I wasn’t in a position to go see him in the ED in an expedient fashion. The ED physician was planning on admitting him and called to notify me. Knowing the history, I suggested sending him home with treatment for the UTI and to follow up with me the next day.
I thought that seemed reasonable, but the ED doctor didn’t. He said, “If you want to do that, then I am going to document that it’s on your instructions, that you are assuming all responsibility for care and outcome if a stroke is missed, and that I entirely disagree with your decision.”
