I practice at Hennepin County Medical Center, a large inner city academic Level 1 Trauma Center. Like all such facilities we have been under a tremendous pressure to reduce costs, and pharmaceutical costs have been a large target. To make us physicians more aware of our prescribing patterns, the Pharmacy has provided us two fascinating lists.
The first list is the top 30 drugs ordered in the emergency department during 2012. It is not very surprising that 6 of the top 10 medications are pain relievers. Interestingly, droperidol (often combined in the same syringe with diphenhydramine) was our #4 used medication, often being given for headache, nausea/vomiting, and agitation. Of note, quetiapine is primarily ordered by psychiatric emergency physicians and is not a typical ED medication.
The second list however, shows the top 30 medications by cost. To protect confidential pricing information, I have normalized the data to $100. Alteplase tops the list and is used almost exclusively for stroke and pulmonary embolism. Surprising to me was tetanus-diptheria-acellular pertussis which is given nonchalantly for our trauma patients. Our first line pain medication is liquid oxycodone (to prevent cheeking), and no surprise it comes in #3. Droperidol, despite being generic is given in large quantities making its total bill high enough to place it #4 on the list. Olanzapine which is only #24 on the frequency list, has been alternative for us when droperidol has been on shortage, and given is patent status, has cost our hospital just about as much as droperidol despite being used 1/2 less frequently.
