Antibiotic Stewardship in Acute Care:
Blurred Boundaries Ripe for Engagement

Emory University
Context and Objectives
• Infectious Disease Epidemiologist, focused on surveillance and policy at federal level
• Thrust into a Hospital System
• Observe tension between limited resources to improve care and payment incentives to improve required metrics
• Describe the context of antibiotic stewardship program acceleration in general, and where it intersects acute care quality concerns
Case – Mrs. J• 85 yo female with moderate dementia and arthritis admitted after
ground level fall at home
• Baseline function: Supervision with ADLs, Dependent with IADLs, Ambulates with a walker
• She was diagnosed with pelvic fracture, Orthopedics consulted and recommended conservative management.
• At time of discharge, she is deconditioned and unable to do her basic ADLS or ambulate
Case Continued - Day 10• Daughter concerned about foul smelling and dark urine
• Vitals normal, no catheter, no change in condition except patient is slightly more confused
• Daughter requested for U/A and now staff is requesting
• On call MD orders UA and culture; no antibiotic started
• After two days, provider notes positive urine culture >100,000 CFU and U/A positive for nitrites, no blood
• Patient stable with no fever or urinary symptoms and mental status improved with hydration
Antibiotics Started8-10 fold increase risk for C. difficile4-8 fold increase risk for antibiotic resistance in GI tract
A lot of Guidance Now - CDC has Advanced the Architecture of Stewardship Across All Healthcare Settings
▪ Adopted by several initiatives as a requirement:– The Joint Commission for their antibiotic stewardship standard– DNV for their antibiotic stewardship standard– Medicare Beneficiary Quality Improvement Project (MBQIP) (QI for
Critical Access) four years (2022) to have a program
The Joint Commission: antibiotic stewardship standard - effective January 2017
▪ Variability in best documentation of compliance
▪ Requirement for family education removed
▪ Some “action” lost in translation around “antibiotic time out”
▪ Still in learning period about what is minimum and outstanding

Increase in Implementation of Stewardship Programs Across All Types of Acute-Care Facilities
▪ Standards 1-7: mostly documentation of commitment, FTE investment, outline of educational sessions, program and committee composition, protocols and order sets in place
▪ Standard 8: Action and Improvement Opportunities
– “Re-active”” vs. “Pro-active” Pharmacist Time
+++++++++++++++
What is relative amount of spent on reactive stewardship?
▪ Examples from the audience Reactive
– Pro-Active
Pro-active Stewardship Requires Robust Data Infrastructure to Target and Prioritize: Hospital Antibiotic Use Data – what metrics
▪ For internal or historical tracking – metric most widely used”
– Days of Therapy (DOT) per 1000 patient days
– Various grouping of antibiotics
▪ DOT/1000 PD or Days Present
– NHSN - 600 hospitals have now reported (some) data on antibiotic use to CDC – requires approved vendor
▪ For external comparison/benchmarking
– CDC risk adjusted benchmark measure of hospital antibiotic use for targeting stewardship programs
• Limited experience with the Standardized Antimicrobial Administration Ratio (SAAR); but endorsed by The National Quality Forum in 2016
• Adjusting for only location type (ICU, surgical; ward medical)
Pros and Cons of AU metrics
▪ ProsElectronically derived a must
Reproducible
Clinically meaningful
Reactive to stewardship and best prescribing
Credible (risk adjusted if possible)
▪ Cons
Manual
Corrective or interpretation needed
Useful only for internal purpose
Poor risk adjustment
Not responsive to stewardship or best practice

Pilot Evaluation of Metrics▪ 5 facilities participated in feasibility assessment
Figure 2. Variation in electronic versus manual extraction of excessive antibiotic duration (2b). Model-based distributions across facilities were plotted for the proportions of hospitalizations with excessive antibotics (b). Distributions obtained from electroinc MUE (dashed lines) are more concentrated, implying less variation, than the corresponding distributions obtained from manual MUE(solid lines).

Duration of use has potential for electronic capture, inpatient and discharge: benefit of electronic capture demonstrated at 30 VAMC
De-escalation: Potential for Electronic Determination
• One Day 4, 5, 6, etc of hospital day assess if de-escalation occurred by combination of
Antibiotic Stewardship Programs in Outpatient SettingNeed for targeted interventions
▪ Outpatient prescribing practices vary greatly across provider-type and professional setting– Among visits for antibiotic-inappropriate respiratory diagnoses, 46% received an antibiotic in
urgent care, versus 25% in emergency departments, 17% in offices and 14% in retail clinics2
▪ Drivers of Better Practice– The Joint Commission—developing new accreditation standard requiring outpatient
stewardship programs
– Private payers
• Aetna audit and feedback intervention
• Anthem providing incentives to providers to implement antibiotic stewardship
▪ Acute Care can have influence over affiliated Clinics: Emory Healthcare exploration of variability in primary care successful 1CDC IQVIA data

Behavioral “Nudge” Works: Public Commitment Posters
▪ Simple intervention: poster-placed in exam rooms with clinician picture and commitment to use antibiotics appropriately
▪ Randomized-controlled trial
▪ Principle of behavioral science: desire to be consistent with previous commitments
▪ “Behavioral nudge” to make the right choice
“As your doctors, we promise to treat your illness in the best way possible. We are also dedicated to avoid prescribing antibiotics when they are likely do to more harm than good.”
▪ Adjusted absolute reduction in inappropriate antibiotic prescribing: -20%

Commitment Posters in Illinois, Texas and New York
Effect of Behavioral Interventions on Inappropriate Antibiotic Prescribing
Meeker, Linder, et al. JAMA 2016;315(6): 562-570.
▪ Cluster randomized trial—47 primary care practices (248 clinicians)
▪ Three specific interventions via Electronic Health Record (0,1,2,3)
– Suggested alternatives
– Accountable Justification
– Peer Comparison
▪ Prescribing rates for visits with inappropriate antibiotics for acute respiratory infections
– Accountable Justification and Peer Comparison resulted in statistically significant decreases
▪ Idea: Clinicians want to preserve their reputation
Peer Comparison
“You are a Top Performer”You are in the top 10% of clinicians. You wrote 0 prescriptions out of 21 acute respiratory infection cases that did not warrant antibiotics.
“You are not a Top Performer”Your inappropriate antibiotic prescribing rate is 15%. Top performers' rate is 0%. You wrote 3 prescriptions out of 20 acute respiratory infection cases that did not warrant antibiotics.

Levers to Improve Nursing Home Antibiotic Use
▪ CDC released Core Elements for Nursing Homes in 2015
▪ CMS finalized long term care requirements of participation in October 2016 requiring antibiotic stewardship to become part of infection prevention and control programs and pharmacy services for 2018.
▪ CMS Quality Innovation Network and Quality Improvement Organizations (QIN-QIOs) recruiting nursing homes to implement CDC’s Core Elements– CDC supporting implementation through expert input and tools
▪ What is the role of Acute Care??

Antibiotic Stewardship Implementation Can Improve Antibiotic Prescribing in Nursing Homes.
▪ A systemic review of 14 studies assessing antibiotic stewardship programs in NHs revealed the following:1
– 8 studies showed a decrease in overall or indication-specific antibiotic prescribing;
– 10 studies reported improved “guideline adherence” as an outcome; and
– None reported a significant change in mortality or hospitalization.
▪ However, studies are needed evaluate outcomes
– Antibiotic resistance
– C. difficile infection2
