Approval Log Located in MGH ASP (antimicrobial stewardship) folder –Daily (if possible) upload or to Christy Purpose: –To keep an accurate log of approvals/indications –Stewardship team insight (since lack of formal note providing indication/purpose) –Follow up on empiric approvals (either you or Christy)

Approval Log Can’t find the ASP folder?  your approval log to Christy –Q 24h-48hrs preferred Feel free to Christy requests to follow up –i.e. did team D/C my antibiotic as I requested? –i.e. did team narrow therapy when cultures finalized?

Stewardship Strategies Bring forward questions or unusual practices so we can work on unifying approval process –Ex. In previous year, rising number of requests for linezolid based on VRE rectal swab Give durations of 72 hrs with empiric approvals with request to follow up with you or ID consult

Common Requests and Clinical Pearls

Linezolid VRE UTI (30% of requests) –Clarify if true infection –If susceptible, amoxicillin, doxycycline and fosfomycin are less expensive alternatives Positive VRE rectal swab –Low PPV 25%, high NPV 98% –If approving, limit to 72hr approval only

Linezolid HCAP –No mortality benefit in linezolid vs vancomycin for nosocomial PNA Vanco allergy and wound infection/cellulitis –Recommend ceftaroline if possible ($80 vs $200) Wunderlink et al. Clin Infect Dis Mar 1;54(5):621-9

Linezolid Recommend PO if patient has no GI absorption issues (highly bioavailable) –If sepsis, consider IV for first dose, and PO for remaining IV to PO ratio is 1:1, goal is 1:4

Carbapenems Necrotizing pancreatitis –No evidence carbapenem is clinically superior (OK to use in culture documented/history of ESBL) –Agents with best penetration: fluoroquinolones, imipenem, ceftazidime, cefepime, metronidazole, clindamycin, chloramphenicol, doxycycline, and fluconazole PCN or cephalosporin allergy –Run through PCN & Ceph Hypersensitivity Pathway Powell JJ et al. Br J Surg. 1998;85: Buchler M, et al. Gastroenterology. 1992;103: Gloor B et al. 2003;26: Shrikhande S et al. Antimicrob Agents Chemother. 2000;44: Bassi C et al. Antimicrob Agents Chemother. 1994;38:

Aztreonam PCN or cephalosporin allergy –Run through PCN & Ceph Hypersensitivity Pathway PSA: –76% susceptible to aztreonam –89% susceptible to cefepime –91% susceptible to ceftazidime

Micafungin QT prolongation fear with azoles –Usually due to drug interactions and multiple QT prolonging drugs with underlying pt risk factors –Azoles unlikely to prolong QT on their own Resistant Candida in urine –Does NOT penetrate into urine –May be okay in upper UTIs

Ceftazidime Globe rupture – approve CNS – approve HD dosing –Renal service likes ceftaz 2g q HD –Note: can also give cefepime 2g q HD Perez, K. Am J Kidney Dis. 2012;59(5):

Voriconazole Resistant UTIs –Does NOT reach urine –May be okay for upper UTIs

Moxifloxacin Restricted to Tuberculosis More costly than other quinolones “Anaerobic coverage” –Poor; recommend levofloxacin/ciprofloxacin plus metronidazole/clindamycin

Other Tips Curbsides: defer to ID consult pager Ask if attending of record has ID privileges –i.e. SICU, MICU, cystic fibrosis, lung transplant –Refer to restricted antimicrobial policy for list of ID approvers Posaconazole is restricted to transplant ID only
