  • For patients with penicillin (PCN) allergies, it is safe to administer third- and fourth-generation cephalosporins (CPN) with no fear of cross reaction.
  • Use of first- and second-generation CPN should only be avoided when the penicillin antibiotic shares structurally similar R1 side chains.

CREST study: Patients presenting to the emergency room with blunt head trauma and preinjury warfarin or clopidogrel use have a high incidence of immediate intracranial hemorrhage, but a very low incidence delayed intracranial hemorrhage. Thus, if the initial head CT is negative, you should be able to discharge the patient home…

  • 100% sensitive and specific if < 6 hours from headache onset
  •  90% sensitive if after 6 hours

A noncontrast head CT can effectively rule out atraumatic subarachnoid hemorrhage (aSAH) in patients who present with acute headache within six hours after ictus. Those who present outside this time window or present atypically for SAH (ie neck pain) require further workup, including a lumbar puncture.

This study tells us what we might already suspect: in the busy, hectic and loud Emergency Department, patients we discharge often lack comprehension of their hospital course. Additionally, they are frequently unable to report their diagnosis, a discharge plan or reasons they should return to the ED.
