Perhaps the patient wouldn't be in status asthmaticus if he didn't have to wait around for the physician to fax over a refill? Besides, you're taking a position that the patient isn't cognizant of his/her condition. Most asthmatic patients have a better idea of their status than anyone. I highly doubt any patient in true status could or would attempt to go anywhere but to the ER. Most patients who can't breathe don't wait in line at the pharmacy. Your reasoning is attempting to err in favor of the patient, and I appreciate that, but at the same time, you're stretching for the zebra, and disregarding the horse. Pharmacists aren't stupid people, and to assume that someone, especially a medical professional, can't recognize a respiratory emergency such as acute SOB when they see one, is a little pretentious. Without getting personal, as I note you are MS (as am I), I would have less confidence that most 1st and 2nd year medical students would be able to identify significant respiratory distress, (being exposed minimally if at all to patient care, than a practicing pharmacist who has not only pharmacy school and rotations, but also experience under their belt). Anyway,I have to believe that an ambulance would be summoned to treat and transport the patient, and that they wouldn't stand around scratching their heads encouraging to hit the albuterol for the 15th time. If the patient were truly to the consideration of being intubated, I, again, highly doubt they would be standing at the pharmacy counter. Most asthmatics just aren't that stupid, and if they are in that amount of denial, then why do you assume they would be cognizant enough to seek medical care anyway, instead of just sitting in their living room waiting to get better.
The fact is, many physicians aren't as accessible as we would like them to be, and in my opinion the overwhelming majority of the time, the benefit would outweigh the risk. In the few cases in which it would not, there are enough confounding variables such as that above, to make it difficult to place specific blame. Again, by having a physician/pharmacist review for each incident would make it a rare case that a pharmacist would opt to use that authority, but the presence of an exception regulation would also protect them, and allow them to act in the best interest of the patient, without fear of legal or professional discipline.
