21 ANTIBIOTIC USE METRICS IN SCI/D METHODS

22 RESEARCH OBJECTIVE The purpose of this study is to report on antibiotic use metrics across all Veterans Affairs (VA) facilities with a special emphasis on Veterans with SCI. Aim 1 Outcome: Prevalence of antibiotic prescribing Overall, by class, and by spectrum of activity Aim 2 Outcome: Antibiotic days (AD) and Days of Therapy (DOT) Overall, by class, and by spectrum of activity

23 METHODOLOGY Study Design: Retrospective cohort study VA Corporate Data Warehouse (CDW) Spinal Cord Dysfunction Registry / Spinal Cord Injury and Disorders Outcomes Study Setting: 1233 VA medical centers, VA outpatient clinics, CBOCs Study Timeframe: January 1, 2013 December 31,

24 ANTIBIOTIC CLASS Systemic antibiotics were grouped into spectrum of activity and class as defined by VA drug classes Inpatient broad spectrum definition: carbapenems, quinolones, anti pseudomonal penicillins, 3 rd /4 th generation cephalosporins Outpatient broad spectrum definition: carbapenems, quinolones, anti pseudomonal penicillins, 3 rd /4 th generation cephalosporins, macrolides, tetracyclines, aminoglycosides 24

25 ANTIBIOTIC USE METRICS Standardized measurements of antibiotic use Can be used to assist in the identification of targets for stewardship efforts Can be used to assist in measuring the impact of stewardship efforts Klepser VeteranS ME, HEALTH al. A call to ADMINISTRATION action for outpatient antibiotic stewardship. J Am Pharm Assoc (press). Dobson EL, et al. Outpatient antibiotic stewardship: interventions and opportunities. J Am Pharm Assoc (press).

26 ANTIBIOTIC USE METRICS Antibiotic days (AD) Average number of days/patient where any antibiotic was administered Max=365 days Days of therapy (DOT) Average number of days/patient where a unique agent was administered No max Calculated at the patient level (across 2013) where >1 day and/or >1 dose of an antibiotic was administered.

27 ANTIBIOTIC USE METRICS - EXAMPLE Levofloxacin Days 5-20 Days 1-8 Piperacillin/tazobactam Day 1 Day 10 Day 20 Antibiotic Days (AD) = 20 days Antibiotics administered on days Days of Therapy (DOT) = 24 days Levofloxacin = 16 total days Piperacillin/tazobactam = 8 total days 27

28 METHODOLOGY Statistical Analyses: Descriptive statistics Independent t test and Wilcoxon Rank Sum for continuous data Chi square test for categorical data A p value < 0.05 was considered statistically significant. 28

38 DOES STEWARDSHIP WORK? CDC. Available at: 38

39 ANTIBIOTIC STEWARDSHIP Why is stewardship needed? Antibiotics are overprescribed Antibiotics are not safe drugs Antibiotic use increases the prevalence of resistance Antibiotic use increases the likelihood of colonization/infection with resistant organisms Associated with poor outcomes and mortality Antibiotic armamentarium is dwindling

40 HOW TO IDENTIFY TARGETS FOR ANTIBIOTIC STEWARDSHIP Compare antibiotic prescribing metrics for your facility to the results presented Prescribing for asymptomatic bacteriuria Prescribing for upper respiratory tract infections See goals in JAMA. 2016; 315(17): De escalation of broad spectrum antibiotic prescribing Quinolone prescribing for acute bacterial sinusitis, (ABS), acute bacterial exacerbation of chronic bronchitis (ABECB), and uncomplicated urinary tract infections (UTI) Per FDA, should be reserved Involve your facility s antibiotic stewardship team FDA.

44 STEWARDSHIP RESOURCES ARE AVAILABLE AT SCI SPECIALTY CENTERS Infectious disease (ID) physician and a pharmacist with ID training Antibiotic stewardship policies and resources: IV to PO antibiotic switching De escalation of antibiotics Clinical guidelines for specific conditions Formulary restrictions Resources necessary to provide effective antibiotic stewardship to Veterans with SCI are available, but translating these resources into effective SCI specific initiatives will require further study. 44 Skelton F, et al.

45 STEWARDSHIP TOOL CUSTOMIZED TO SCI/D Implementation of an antimicrobial stewardship tool, an antibiogram An aggregated report of bacterial susceptibilities to antibiotics for a specific facility, population, or community Single center study: Veterans with SCI were younger and sicker as compared to a general acute care population MRSA, ESBL, carbapenem resistant and CRE were more frequent Hill JN, et al.

46 POLL QUESTION In the past year, how often have you used facility antibiograms (trends in antimicrobial resistance) in determining treatment for SCI patients? All of the time Some of the time Seldom Never 46

47 POLL QUESTION Are you interested in having an SCI specific antibiogram for your facility? Yes No If yes, we are assembling them for interested SCI specialty centers with support from SCI/D Services. Contact Dr. Suda if interested 47

48 STUDY CONCLUSION A greater proportion of Veterans with SCI received antibiotics with longer antibiotic days and days of therapy as compared to a non SCI VA cohort. While patients with SCI are reported to have more infections than those without SCI, the high prevalence of broad spectrum antibiotics is concerning. Thus, effective antibiotic stewardship strategies should be implemented in VA to target SCI and other special populations with high antibiotic use and at high risk for MDROs.
