Improving Antibiotic Use Across the Continuum of Care: Stewardship Opportunities in the Outpatient Setting

Transcription

1 Improving Antibiotic Use Across the Continuum of Care: Stewardship Opportunities in the Outpatient Setting Chloe Bryson-Cahn, MD Chief Fellow, Infectious Disease University of Washington UW Tele-Antimicrobial Stewardship Program (UW TASP) This presentation is intended for educational use only, and does not in any way constitute medical consultation or advice related to any specific patient.

2 Learning Objectives Recognize the role of antimicrobials in health care and how misuse leads to unintended consequences. Identify ways to improve antibiotic use in outpatient settings. Identify the Four Core Elements of Outpatient Antibiotic Stewardship and describe methods of achieving them.

3 Disclosures Financial Disclosures: None

4 A Local Reality 19 year old man suffered a traumatic open leg injury in India arrives at Harborview Medical Center in Seattle for surgical revision of his amputation. Wounds found to be infected with MDR Pseudomonas aeruginosa and Klebsiella pneumoniae.

5 Global Antimicrobial Resistance

6 Global Antimicrobial Resistance

7 Antibiotic Overuse

8 Albrich, Emerg Infect Dis 2004 Antibiotic Use and Resistance

9 From the CDC Antibiotics are in the top three drug classes leading to adverse drug event related ER visits for all ages. Antibiotic resistant infections -> higher healthcare costs poor health outcomes more toxic treatments Antibiotic overuse strongly associated with the rise of C.diff infection

10 Antibiotic Prescribing for Dental Procedures in Community Associated Clostridium difficile cases, Minnesota, Dentists prescribe 10% of outpt antibiotics 15% of antibiotic associated C.diff infection cases in this study were dentist prescribed Conclusion: Dental antibiotic prescribing rates and sideeffects are likely underestimated C.diff infections from dentist prescribed antibiotics are not reported back Bye, IDWeek 2017

11 The Bright Side A 10% decrease in inappropriate antibiotic prescribing in the community -> nearly 20% reduction in C.diff infection. Effective stewardship programs Decrease rates of antibiotic associated nephrotoxicity Increase guideline concordant treatment (shown to impact mortality) Decrease resistance at the population level Dantes, OFID 2015 Schuts, Lancet 2016

12 Why Care about Outpatient Stewardship Per Year in the US 35 million hospitalizations 141 million ED visits ~ 1 Billion outpatient visits 75%+ of antibiotic prescribing is done in the outpatient setting

21 CDC Core Elements Antibiotic Stewardship

22 Action for Policy and Practice Implement at least one policy or practice to improve antibiotic prescribing, assess whether it is working, and modify as needed. Opportunities/ Evidence based strategies: Use evidence-based diagnosis/ treatment (IDSA, A2SC) Local antibiograms Diagnostic stewardship Written justification Improve triage systems

23 Improving Triage Systems 454,484 calls for URI symptoms managed by RN over the phone Harper, A J Manag Care, 2015

24 CDC Core Elements Antibiotic Stewardship

25 Tracking and Reporting Monitor antibiotic prescribing practices and offer regular feedback to clinicians, or have clinicians assess their own antibiotic prescribing practices themselves. Goal: individual prescriber level, use data Opportunities/ Evidence based strategies: Monitor documentation of indication for Rx Adherence to facility guidelines Peer comparison

26 What are you Going to Measure? Measures of antibiotic use: Prescription Pharmacy dispense Consumption (pill counts?) Inappropriate Guideline concordance Volume of antibiotic prescribed Prescription per unit time Percent prescribing by individuals/ season Linder, IDWeek 2017

27 What are you Going to Measure? Denominator Per visit Per population Primary Outcome This is the real target of your stewardship project Secondary Outcome Recommend eval for squeeze or dx shifting All antibiotic prescribing Linder, IDWeek 2017

30 CDC Core Elements Antibiotic Stewardship

31 Education and Expertise Provide educational resources to clinicians and patients on antibiotic prescribing, and ensure access to needed expertise on optimizing antibiotic prescribing. Opportunities/ Evidence based strategies: Effective communication with patients Patient education Staff and clinician education Ensure access to expertise

32 Strivers, J Fam Practice 2003 Communication Education

33 Communication Education A forthcoming publication

34 Expertise: TASP Provide: Once weekly meeting between WA state critical access hospitals and UW 2 ID trained faculty, many ID fellows ID trained Pharmacists Microbiology fellow Pharmacy and Medical Students and Residents Washington DOH CE credits available (CME, CNE, and pharmacy)
