3 Objectives 1. Develop an awareness and understanding of what antibiotic stewardship is. 2. Appreciate the concerns regarding inappropriate antibiotic use. 3. Discuss local project in the development of protocols for antibiotic use in LTC.

4 Clinical Case ID: 76yo female admitted April 2012 to local community hospital RFA: presumed pneumonia PMH: non-remarkable, healthy SHx: living independently, physically active, engaged in community

5 Clinical Case Course while hospitalized: Treated with IV antibiotics-respiratory fluoroquinolone for 10 days course in April On proposed day of discharge, contracted symptomatic C. difficile Roommate in semi private room had C. Difficile Treated in-hospital for CDI with multiple courses of Abx from May-August 2012

6 Clinical Case Discharged home on August 20 th with resolution of CDI Became symptomatic again with diarrhea and retested by family physician for CDI Readmitted on Sept 6 th 2012 for confirmed CDI and died Sept 7 th 2012 Cause of death on death certificate: C. Difficile

7 Antibiotics We need to use best evidence and guidelines for the treatment of Pneumonia, Urinary Tract Infection or Soft Tissue infection we can do better.

8 What is Antibiotic Stewardship? Is it important?

9 Why Do We Need to Improve Antibiotic Use?-PATIENT SAFETY Antibiotics are misused in hospitals and LTC Antibiotic misuse affects both patients and society Improving antibiotic use improves patient outcomes and saves money Improving antibiotic use is a public health imperative

10 Antibiotic Misuse It has been recognized for several decades that up to 50% of antimicrobial use is inappropriate. IDS/SHEA Guidelines for Antimicrobial Stewardship Programs

11 What is Antibiotic Misuse?D s Diagnosis: Right drug for problem DRUG: Pick best antibiotic based on guideline DOSE: Prescribed at the incorrect dose DURATION: Prescribed for the correct duration Dollars: Use narrow spectrum first

12 Consequences of Antibiotic Misuse Antibiotic associated infections (C. difficile) Antibiotic resistance Adverse drug effects or drug interactions Increased costs

13 C Diff Seasonality-IATROGENIC

14 Antibiotic Associated Infections Antibiotic exposure is the single most important risk factor for the development of Clostridium difficile associated disease (CDAD) Up to 85% of patients with CDAD have antibiotic exposure in the 28 days before infection 1 1. Chang HT et al. Infect Control Hosp Epidemiol 2007; 28:

15 CDI Emergence of the NAP-1/BI or epidemic strain of C. difficile has intensified the risks associated with antibiotic exposure. Epidemic strain of C. difficile is associated with increased risk of morbidity and mortality. Epidemic strain is resistant to fluoroquinolone antibiotics, which confers a selective advantage.

22 What is Antibiotic Stewardship? A program that encourages judicious use of antibiotics Antibiotics are so effective, non-toxic and inexpensive that they are easy to use and so, prone to misuse Stewardship strives to optimize antibiotic therapy Maximize effectiveness Minimize toxicity Reduce selection for resistance Optimize costs Encourage step-down and discontinuation

23 Examples of ASP TOPS (Towards Optimized Practice) Infectious Disease Society of America (IDSA) Society for Healthcare Epidemiology of America (SHEA) CDC Get Smart: Know when antibiotics work

24 Common Infections in LTC UTI Respiratory Skin and soft tissue infections CDiff

25 Antibiotic Use in LTC Antimicrobials are among the most frequently prescribed pharmaceutical agents in LTC accounting for approximately 40% of all prescribed systemic drugs Point prevalence of systemic antibiotic use is approximately 8% 50-70% likelihood that a resident will receive at least once course of a systemic antimicrobial agent during a 1 year period 22-89% of antibiotic prescription in LTC are inappropriate 1.

26 Antibiotic Misuse in LTC Patient Factors Atypical clinical presentation Impaired communication Difficulty obtaining specimens Family concerns System Factors Limited diagnostic resources Limited staff with time constraints Lack of continuity of care Provider Factors Lack of information at time of decision making Limited direct evaluation Lack of knowledge

37 Summary Antibiotic misuse occurs in all health-care settings Antibiotic misuse has significant consequences for patients and society Appropriate antibiotic use is a Public Health imperative Antibiotic Stewardship is key
