Contributor: Aaron Lessen, MD Educational Pearls: Retrospective cohort study in the Kaiser system looked at over 4 million patients receiving antibiotics to determine the effect of penicillin allergy prompts in the EHR on antibiotic prescribing Half of the sites removed prompts stating penicillin allergy and half kept the prompts Patients with penicillin allergies who received cephalosporins went up from 20% to 27% in areas where the prompt was remove No difference in mortality or no new allergies found between the two groups Reduced the use of fluoroquinolones and clindamycin in the group without the prompt References Macy E, McCormick TA, Adams JL, et al.

Contributor: Aaron Lessen, MD Educational Pearls: Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals Some connect to a continuous glucometer but often blood glucose needs to be checked manually Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin The pump can be used to give a bolus of insulin in the emergency department if necessary Stopping the device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible References Nimri R, Nir J, Phillip M.

Contributor: Nick Tsipis, MD Educational Pearls: Prospective trial studied 5 mg IM droperidol to 10 mg IM olanzapine (Zyprexa) in the reducing levels of agitation Time to adequate sedation was about 16 minutes for both agents Droperidol was slightly less sedating than olanzapine and length of stay for olanzapine was longer Olanzapine had a higher rate of requiring another agent for adequate sedation Droperidol had a higher rate of adverse events (mainly extrapyramidal symptoms) than olanzapine Remember to put the safety of the staff and patient at the forefront of sedation practices and be cognizant of the psychological effect of giving involuntary medications to patients References Cole JB, Stang JL, DeVries PA, Martel ML, Miner JR, Driver BE.
