Alice Guh, MD, MPH Division of Healthcare Quality Promotion Centers for Disease Control and Prevention CSTE CRE Panel Session – June 14, 2011 Public Health Response to Carbapenem-Resistant Enterobacteriaceae: The Role of Health Departments National Center for Emerging and Zoonotic Infectious Diseases Division of Healthcare Quality Promotion

Carbapenem-resistant Enterobacteriaceae (CRE)  Common cause of HAIs  Found in both acute care hospitals and long-term care settings  Since 2004, reports of CRE cases from LTACH and LTCF  Similar to the spread of other MDROs  Movement of colonized patients across the continuum of care contributes to regional transmission  Supported by mathematical modeling Urban C et al. Clin Infect Dis 2008;46:e Endimiani A et al. J Antimicrob Chemother 2009;64: Smith DL et al. PNAS 2004;101:

Inter-Facility Transmission of MDROs (Including CRE) Munoz-Price SL. Clin Infect Dis 2009;49:

Regional Approach to MDRO Prevention is Essential  Rationale for regional approach  What happens in one facility will impact surrounding facilities  Individual facilities can reduce MDRO prevalence only to a certain point  Successful regional coordination by public health  VRE control in Siouxland region  CRE containment in Israel Sohn AH et al. Am J Infect Control 2001;29:53-7. Schwaber MJ et al. Clin Infect Dis 2011;52:

How to Operationalize Public Health Response to Emerging MDROs  Opportunity to apply regional approach to CRE prevention  HDs in unique position to coordinate local and regional response to CRE  Assess CRE prevalence/incidence within their jurisdiction in order to provide situational awareness to facilities  Serve as resource to facilities about prevention options  Informs public health response to other emerging MDROs

DEVELOPMENT OF CRE TOOLKIT

Outline of CRE Toolkit  Facility-level prevention strategy for facilities and HDs  Regional prevention strategy specifically for HDs  Aggressive approach to contain or prevent CRE emergence Regions with no CRE identified Regions with few CRE identified

Regional Prevention Strategy Regional Surveillance for CRE  Determine CRE prevalence within a given jurisdiction  Make CRE laboratory reportable (in regions with no known or few CRE)  Survey IPs or lab directors  Feedback of surveillance results  Provide specific enough data for facilities to act upon Facility name, if possible or Stratify results by geographic area and/or by facility type

Regional Prevention Strategy Regions With No CRE Identified Aggressive efforts at detection:  Perform periodic surveillance and feedback  Frequency may depend on CRE prevalence in neighboring regions (establish mechanism for communication)  Educate facility staff to increase awareness  Epidemiologic importance of CRE  Recommended surveillance and prevention measures* *

Regional Prevention Strategy Regions With Few CRE Identified Aggressive efforts at containment, may target select areas:  Implement infection prevention measures  Reinforce core prevention measures in all facilities  Facilities with CRE: use supplemental measures  Facilities without CRE: targeted surveillance testing, preemptive CP  Use inter-facility patient transfer forms  Indicate CRE status, open wounds/devices, antimicrobial therapy  Educate facility staff to increase awareness  Perform periodic surveillance and feedback

REGIONAL CRE SURVEILLANCE BY SELECT HEALTH DEPARTMENTS

Development of CRE Survey  Fall 2010 – CRE conference calls with interested HDs to identify actionable steps to take  HDs notified through CSTE HAI listserve  CRE survey template designed to be used by HDs to assess CRE prevalence within their jurisdiction  7 questions to administer to IPs of acute care facilities  Estimate frequency of CRE colonized- or infected-patients  Assess facility-level surveillance activities for CRE and related prevention measures* *

State HDs Conducting CRE Survey (n=7)  Utah  Illinois  Virginia  Idaho  South Carolina  West Virginia  Wisconsin

Administration of CRE Survey  Targeted acute care hospitals, but included:  Long-term acute care hospitals (≥3 states)  Critical access hospitals (≥2 states)  Survey methods by HDs  /online survey (e.g., Survey Monkey) to IPs  Paper survey at APIC meetings  Date of survey: ranged Sep 2010-Mar 2011  Survey lasted one day to 2-3 months  Sent reminder s, phone calls to non-respondents

Survey Respondents  Aggregated state-level data across all 7 states:  Median response rate – 67% (range: 26% to 100%)  Breakdown by bed size (n=6 states): Total 360 facilities  ≤50 beds – 30%  beds – 39%  beds – 27%  >500 beds – 4%  Fairly representative of national data (2008 AHA data)  Except greater % of facilities with ≤50 beds captured in survey

CRE Prevalence in Past 12 Months (n=7 states) Percentage of Facilities Per State CRE PrevalenceMedianRange Identified CRE Daily or weekly00-16 Monthly or greater ≤48 hrs of admission >48 hrs of admission Do not know if have CRE

CRE Surveillance Measures (n=7 states) Percentage of Facilities Per State Surveillance measuresMedianRange System for micro lab to alert IP staff Review prior micro data* If yes, identified CRE Conduct point prevalence survey If yes, identified CRE Conduct AST of epi-linked patients *Applies to facilities that have not or have rarely identified CRE cases (data available for 6 states)

CRE Prevention Measures (n=7 states) Percentage of Facilities Per State Prevention measuresMedianRange Place on Contact Precautions Place in single-patient rooms

Summary of CRE Survey Results  CRE identified in <50% of all responding facilities, still have opportunity to prevent full emergence  Although there is intra-facility transmission, majority of identified cases are imported  Important role of inter-facility patient sharing  Supports the need for regional approach to prevention  Low facility adherence to recommended surveillance practices and need for increased education / awareness  Potential under-reporting of CRE

Feedback of Survey Results by HDs  At least 5 states provided feedback to IPs / facilities  (memo, monthly HAI newsletter)  Presentation at APIC meeting  Feedback content  Only shared aggregated results Some stratified by geographical region (n=2), facility type (n=1)  Some provided streamlined 2009 MMWR guidance* (n=3) *

INTERVIEWS WITH STATE HEALTH DEPARTMENTS

Key Informant Interviews  Primary objective: to understand why some HDs decided to conduct CRE survey and others did not  Participants  All 7 states that conducted CRE survey  4 additional states that did not conduct CRE survey (participants of initial CRE calls via CSTE HAI listserve)  Standardized script with trained interviewer

Key Interview Findings (n=11 states)  All HDs communicated regularly with IPs about HAI topics in previous 12 months (prior to CRE survey)  No difference between states in competing priorities and concerns about CRE survey  Main concern – perception of overburdening IPs  Yet perspectives differed regarding conducting survey: opportunity to learn vs concerns about survey intent and logistics and other data source  Assess for other confounders and contextual factors  Evaluate alternative sources to IPs for information
