This week, Dr. Bryan Hayes – Clinical Pharmacologist and expert in Toxicology gives an amazing talk highlighting 10 of his top tips for antimicrobial use in the emergency department & for the critically ill patient.  This is probably one of the most clinically useful lectures I’ve listened to in a long time.  Bryan has actually started his own campaign to make sure we are all using Vanc right in 2014 – he even made it a New Years Resolution of his own (Check out his post on Academic Life in EM)

Pearls

* How to correctly give a dose of vancomycin

* Dose: 15-20 mg/kg every 8-12 hours in patients with normal renal function, MAX: 2 grams
* Consider an even higher loading dose In seriously ill patients (e.g. sepsis, meningitis, infective endocarditis) with suspected MRSA infection: 25-30 mg/kg — again, MAX 2 grams (ISDA recommendation).
* Weight based dosing by using actual body weight
* In adults, we round to the nearest 250 mg increment (to help out your friendly pharmacist)


* In the critically ill obese patient, aminoglycosides should be dosed by adjusted body-weight

* ABW = Ideal BW + 0.4*(Actual BW – Ideal BW)


* A Penicillin allergy is NOT a contraindication to cephalosporin use!

* 3rd, 4th, & 5th Generation cephalosporins can be safely given to PCN allergic patients.
* Avoid keflex, cefaclor, cefadroxil, cefprozil as their beta lactam side chain is similar to PCN.
* Carbapenems are also safe in PCN allergic patients


* HCAP “double coverage” should include only 1 beta-lactam antimicrobial, the 2nd agent should have a different mechanism of action (i.e. fluoroquinolone, etc.)
* Don’t forget the atypical coverage in HCAP patients!  Send the urine legionella antigen.
* CAP patients admitted to the ICU should not be treated with a fluoroquinolone alone.  Add the beta-lactam.

Thanks Bryan – we’ll make sure to get it right in 2014.
