GNYHA-UHF Antimicrobial Stewardship Project • The overall objective was to develop and test strategies and tools that can be used by health care facilities to implement an effective and sustainable antimicrobial stewardship program. • Specific objectives included: • To establish antibiotic stewardship programs (ASP) in acute care hospitals and LTCF using existing personnel and resources • To establish acute care hospital-LTCF collaborations related to ASP • To develop and pilot tools for ASP development and implementation in other health care facilities • To identify best practices for and challenges associated with ASP implementation
GNYHA-UHF Antimicrobial Stewardship Project 3 acute care hospitals were selected from among those participating in the C. difficile collaborative. Chosen hospitals were required to recruit a long-term care facility partner to participate in the project. October 2009-June 2010
Interventions • Develop a stewardship team. • Participate in meetings and conference calls. • Assess current practices and resources. • Identify and prioritize ASP target areas. • Select and implement interventions.
Project Outcomes • In a short period of time and without additional resources, hospitals and long-term care facilities were able to introduce antimicrobial stewardship programs into their facilities. • Qualitative data suggest that the programs were beneficial.
Outcomes: Examples of Success • Successful hospital interventions: • Expansion of activities to 3 new units (acceptance ~100%) • Completion of an IRB-approved study of practices related to UTI diagnosis and treatment, involving students and residents, resulting in development and revision of guidelines • Successful LTCF interventions • Presentation of baseline data on inappropriate antimicrobial use for asymptomatic bacteriuria to Medical and Nursing Directors, leading to a facility-wide PI Project with development of a protocol for UTI diagnosis and treatment • Development of a restricted antibiotic list • Review of urine culture results with subsequent interaction with clinicians
Outcomes: Examples of Success • Hospital-LTCF Collaborations • At least one hospital-LTCF team began having joint ASP meetings that involved LTCF medical director. • At one site, hospital pharmacists were granted access to LTCF resident drug profiles to assist with stewardship activities.
Educational materials • Marketing materials • Tools for stewardship teams
Outcomes: Lessons Learned • Antimicrobial stewardship is complex: there is not a “one size fits all” bundle. • Keys to success: • A motivated team • Support from administration and medical leadership • Data • Access to ready-made tools to assist ASP activities • A forum to discuss challenges and best practices
Greater New York Infection Prevention Challenges
General Challenges • Space constraints • Hospital closures • Permanent • Temporary • Infection Prevention staffing • NYSDOH annual survey showed stable IP to bed ratio, but certainly no increase over past few years despite greater demands. • How do we ensure that best practices are consistently applied? • We are improving, but so is everyone else.
Ongoing CLABSI Challenges • The 2011 NYC CLABSI rate is significantly higher than the NYS average. • SIR 1.15 (1.05-1.25) • The New York State CLABSI rate is higher than the US average. • 2010 NYS SIR was 25% higher than that of the US overall. • In 2009, 17 states used NHSN to satisfy a state-specific CLABSI reporting mandate. • New York had the fourth highest CLABSI SIR. • The 5 states that had a data validation program had the 5 highest SIRs among the 17 states. • CLABSI prevention efforts in non-ICU settings are lagging.

Prevalence of CRE Among Inpatients in Two NYC Hospitals The overall prevalence of CRE was 5.4%. The average monthly prevalence was 7.4%. 68% of carriers were identified by active surveillance alone. Calfee DP. Unpublished data.
Frequency of and Risk Factors for Acquisition of CRE • Independent predictors of CRE acquisition included: • Pulmonary disease (OR 11.53, p=0.02) • Mechanical ventilation (OR 5.19, p=0.04) • Days of antibiotic therapy (OR 1.04, p=0.003) • CRE colonization pressure (OR1.15, p=0.01) • The odds of acquiring CRE increased by 4% for every day of antibiotic therapy received and by 15% for every 1% increase in the colonization pressure to which a subject was exposed. Calfee DP. Unpublished data.
Compliance with Infection Control Measures Reduces Risk • Compliance with infection prevention policies can reduce the association between prevalence and incidence of CRE. Schwaber MJ. Clin Infect Dis 2011;52(7):1-8
Regional MDRO Control Initiatives • Intervention included: • Mandatory reporting of all CRE patients • Mandatory isolation of hospitalized CRE carriers • Contact precautions (index and subsequent admissions) • Cohort nursing • National Task Force with authority to collect data and intervene as needed. National guidelines for active surveillance and intervention in LTCF issued Schwaber MJ. Clin Infect Dis 2011;52(7):1-8
Antimicrobial Stewardship Programs Johannsson B. Infect Control Hosp Epidemiol 2011;32:367-74 • Despite evidence of benefit, not all health care facilities have introduced such programs. • 79% of university hospitals • 40% of community hospitals • Almost unheard of in long-term care facilities • Lack of funding and personnel are the most commonly reported barriers.
Policy Statement on Antimicrobial Stewardship: SHEA, IDSA, PIDS • Antimicrobial stewardship programs should be required through regulatory mechanisms. • Antimicrobial stewardship should be monitored in ambulatory healthcare settings. • Education about antimicrobial resistance and antimicrobial stewardship must be accomplished. • Antimicrobial use data should be collected and readily available for both inpatient and outpatient settings. • Research on antimicrobial stewardship is needed. SHEA, IDSA, PIDS. Infect Control Hosp Epidemiol 2012;33(4):322-7
CMS: Conditions of Participation for Infection Control • Facility has a multidisciplinary process to review antimicrobial utilization, local susceptibility patterns, and antimicrobial agents in the formulary and there is evidence that the process is followed. • Systems are in place to prompt clinicians to use appropriate antimicrobial agents (e.g., computerized physician order entry, comments in microbiology susceptibility reports, notifications from clinical pharmacist, formulary restrictions, evidenced based guidelines and recommendations). • Antibiotic orders include an indication for use. • There is a mechanism in place to prompt clinicians to review antibiotic courses of therapy after 72 hours of treatment. • The facility has a system to identify patients currently receiving intravenous antibiotics who might be eligible to receive oral antibiotic treatment. Currently, deficiencies in these criteria will NOT result in citation, but... CMS. October 2011. https://www.cms.gov/Surveycertificationgeninfo/downloads/SCLetter12_01.pdf
HCW Influenza Vaccination • In a CDC survey of the 2011-12 season, 66.9% of HCP reported having received flu vaccine. • Physicians 85.6% • Nurses 77.9% • Others: 62.8% • Vaccination coverage was 76.9% among HCP in hospitals. • Only 44% of HCW in NY received influenza vaccine. • CMS-required reporting of healthcare worker influenza vaccination (via NHSN) begins January 2013. • Joint Commission requires hospitals to set incremental influenza vaccination goals, achieving 90% by 2020. • How will we get to >90%?

Greater New York Infection Prevention Opportunities
New Appreciation for Healthcare-Associated Infections • HAIs are an important cause of morbidity and mortality among patients in US hospitals. • HAIs are not inevitable consequences of health care. • HAIs are largely preventable. • A “very low” rate of infection isn’t low enough for the patient that develops the infection. • Everyone shares the responsibility for preventing these infections.
Opportunities and Obligations • Advocacy and engagement • Professional societies: APIC, SHEA • Organizations: healthcare facilities, GNYHA, HANYS • Individual involvement: local, state, federal level • Epidemiologic, clinical, and basic research • Eliminate knowledge deficits • Optimize use of limited resources • Multicenter, high-quality studies • Develop new technology • Cost-effectiveness research • Utilize new sources of funding for research • NIH, AHRQ, CDC, NYSDOH, foundations, industry
Opportunities and Obligations • Innovative approaches to improving practice • Implementation science • Systems engineering • Bundles and checklists • Behavioral science • Root cause analysis • Positive deviance • Collaboration
