Why the concern with QuinolonesFrom 2003 to 2006, C. difficile infections are observed to be more frequent, more severe, more refractory to standard therapy, and more likely to relapse than previously described .
Some cases have been attributed to a new strain designated BI, NAP1 or ribotype 027. • Fluoroquinolone use has strongly correlated with the emergence of this strain. • Antibiotic use is the most widely recognized and modifiable risk factor for C. difficile-associated diarrhea (CDAD) • The use of broad-spectrum antimicrobials, use of multiple antibiotic agents, and increased duration of antibiotic therapy all contribute to the incidence of CDAD
PREVIOUS USAGE OF QUINOLONES AT MARLBOROUGH HOSPITAL • Moxifloxacin formulary quinolone (FQ). No renal dosing (400 mg po/iv daily). Does not cover UTI. Ciprofloxacin reserved for these patients.
QUINOLONE RESTRICTIONS • As of 12/1/10 FQ restriction to ID. • 24 hour supply allowed. • Pharmacy contacts via communication sheet/paging MD. • ID contacted via email. • Further supply restricted to ID approval.
COMMUNICATION SHEET USED Communication Sheet From: Pharmacy To: Flouroquinolone restriction Dear doctor A flouroquinolone has been ordered for this patient.

MEDITECH DATA FOR QUINOLONE USAGE Definitions • # RX- # of orders entered in Meditech system (1 patient with 1 renewal order and dosing/route changes can have 2 RX) • # Pts- # patients listed in reporting • # RX > 24 hours- RX with start and stop times > 24 hours entered From 12/10 on- checked individual patients with > 24 hours to validate if patient received > 1 day dosing.

MEDITECH REPORTING • Monthly analysis for August to March 1-16th for time frame of 8/09 to 3/16/11 • Antibiotics used for analysis: Ertapenum (E), Vancomycin (V), Ceftriaxone (CF), Levofloxacin, Ciprofloxacin, and Moxifloxacin • Levofloxacin, Ciprofloxacin, and Moxifloxacin data aggregated (FQ) • #RX and # PT collected.
#RX ABX SPREAD • Quinolone most prescribed antibiotic in Feb 2010. • Ceftriaxone most prescirbed antibiotic overall during winter months.
#PTS ABX DATA • Decline of patients on quinolones since December 2010. • Does not take account if patient switches antibiotic or has multiple drug therapy.
% ABX orders comparing the four drugs • Ertapenum usage initially high, now consistent. • Ceftriaxone use increased with less usage of FQ and vice versa. • ? Increase use of Vancomycin after winter months.
CONCLUSION • ONE TIME DOSES (OVERIDES, SDC PATIENTS) • SIGNIFICANT DROP OF TREATMENT OF QUINOLONES IN HOSPITAL INPATIENT FLOORS. • TIMELY COMMUNICATION ESSENTIAL • INITIAL SELECTION FOR CAP REMAINS 100%
