Trends and Strategies for Prevention of Healthcare-Associated Infections Alice Guh, MD, MPH Division of Healthcare Quality Promotion Centers for Disease Control and Prevention
Healthcare-Associated Infections (HAIs) • Definition: Infections that patients acquire during the course of receiving treatment for other conditions within a healthcare setting • Healthcare settings: • Hospitals: acute care facilities, critical access hospitals • Long term care facilities (LTCF) • Outpatient settings: dialysis centers, ambulatory surgical centers, physician’s offices
Your baby was born prematurely. She was progressing in the neonatal intensive care unit until she developed a bloodstream infection related to her umbilical catheter.
Your father has open heart surgery. The surgery goes well but he later dies in a nursing home of a MRSA wound infection that developed after surgery.
Your sister contracts Clostridium difficile after giving birth. She has lived with this unbearable infection through 6 months of relapses.
Your mother is being treated for cancer • And now has to fight two diseases because she got Hepatitis C from an unsafe injection
HAI BurdenWhat is Known: Acute Care Settings • 1.7 million infections (5% of all admissions) • Most (1.3 million) were outside of ICUs • $28–33 billion in excess costs • 99,000 associated deaths • Most common type of infections: • Bloodstream infections (BSI) • Urinary tract infections • Pneumonia • Surgical site infections Klevens, et al. Pub Health Rep 2007;122:160-6
National Estimates of U.S. Short-Stay Hospital Discharges with C. difficile McDonald LC, et al. Emerg Infect Dis. 2006;12(3):409-15
Tranquil Gardens Nursing Home The Healthcare System More than Just Hospitals Acute Care Facility Home Care Outpatient/ Ambulatory Facility Long Term Care Facility
HAI Burden Outside of Acute Care • We know much less about this • What we have learned to date: HAIs are a substantial problem outside of acute care settings
HAIs in LTCF • 1.7 million beds with 2.5 million residents / yr1 • 1/3 of long-term care residents affected by respiratory disease outbreaks2 • Veterans Healthcare data3 • 133 nursing homes; 11,475 residents • HAI prevalence: 5.2% • Indwelling medical device: 25% of all residents 1NCHS, 2009 2Loeb, CMAJ, 2006 3Tsan, AJIC, 2008
Growth in Outpatient Care • Shift in healthcare delivery from acute care settings to ambulatory care, long term care and free standing specialty care sites • Dialysis Centers • 2008: 4,950 (72% increase since 1996) • Ambulatory Surgical Centers • 2009: 5175 (240% increase since 1996) • Approximately 1.2 billion outpatient visits / yr

Hospital (27) OutpatientSetting (12) LTCF (3) Community(5) Healthcare-associated Outbreak Investigations by Healthcare Setting, 2004-2008 • Increasing number of outbreaks associated with outpatient care • Wide range of settings (e.g., ambulatory surgery, cancer clinics, pain medicine, dialysis, long-term care, physician offices) • Unsafe injections, foundation of basic safe care practices lacking n = 47, as of April 2008
SOURCE Infectious person, e.g. chronic, acute CASESusceptible, non-immune person TRANSMISSION OF BLOODBORNE PATHOGENS VIA CONTAMINATED EQUIPMENT OR MEDICATIONS CONTAMINATED EQUIPMENT OR MEDICATION OR HANDS
33 outbreaks in 15 states • Outpatient clinics, n=12 • Dialysis centers, n=6 • Long term care, n=15 Thompson et al. Ann Intern Med. 2009;150:33-39.
Viral Hepatitis Outbreaks - Outpatient Settings Thompson et al. Ann Intern Med. 2009;150:33-39.
Ongoing Threat to Patient Safety • Continued outbreaks associated with unsafe injections and other breakdowns in basic infection control • Large public health patient notifications advising testing for hepatitis B virus, hepatitis C virus, and HIV
Infection Control in Outpatient Settings • Sub-optimal infection control infrastructure and oversight • Approximately 50% of ambulatory surgical centers (ASC) surveyed by CMS and CDC had serious, noncompliance with the Medicare ASC health and safety standards • 28% had unsafe injection practices
State of Prevention Knowledge and Science • Evidence-based prevention recommendations • Major device and procedure associated HAIs (CLABSI, VAP, CAUTI, SSI) • Prevention of pathogen transmission (MRSA, C. difficile) • Suboptimal adherence to key prevention recommendations
Current State of Affairs • Hand hygiene compliance for healthcare worker: 40-50% • Compliance with timing of surgical prophylaxis was ~40%1 • Many facilities have yet to implement proven prevention measures: • Bloodstream infections • Urinary tract infections 2005 Data from Surgical Care Improvement Project
What’s Been Missing in the Past to Promote HAI Prevention? • Robust data on HAI Prevention • Focused attention of policymakers on HAI prevention • Incentives / disincentives to promote systems change for sustainable HAI prevention • Framework to extend local / regional successes across the nation

Preventability of Infections • Study on the Efficacy of Nosocomial Infection Control (SENIC) • 6% of all HAIs preventable with minimal infection control efforts • 32% preventable with “well organized and highly effective infection control programs” • 20-70% of infections are preventable1 1J Hosp Infection 2003;54:258
Trends in MRSA Bloodstream Infections by ICU Type, NHSN hospitals, 1997-2007 • Estimated 7000 BSIs prevented • 1800 lives saved • $50-180 M in costs averted annually
Significant reductions: • Surgical site infections • Unplanned return to OR • All complications • Deaths Haynes AB, et al. NEJM 2009;360:491-9.

Tranquil Gardens Nursing Home Increasing Needs and Opportunities for Public Health Approach Across the Continuum of Care Acute Care Facility State Health Departments Home Care Outpatient/ Ambulatory Facility Long Term Care Facility
A New Paradigm: Central Role of State Health Departments • Expanding state public health workforce to make progress toward HAI prevention • Create and expand state-based HAI prevention collaboratives • Sustainable statewide efforts will contribute to national healthcare improvement efforts
A New Model For Prevention:Prevention Collaboratives • Experience is showing that multi-facility collaborative projects are the gold standard in HAI prevention • Many “change methods” that have demonstrated success: • Comprehensive Unit-based Patient Safety Program (CUSP) • Positive deviance • Six-sigma
Basics of a Prevention Collaborative • Group of healthcare facilities engaged in a common effort to reduce HAIs • Members use a common approach • Discuss progress regularly and share lessons learned in real time
What is the Minimum Size of a Prevention Collaborative? • 2 or more facilities working together meaningfully • Ideal size multi-factorial • Specific subject or targeted HAI • Type of healthcare facilities • Available resources • More “cutting edge” ─ smaller number • More established “change packages” can be quite large • Level of enthusiasm
Prevention Strategies Supplemental Strategies Some scientific evidence Variable levels of feasibility • Core Strategies • High levels of scientific evidence • Demonstrated feasibility
Regional Prevention CollaborativesExamples of Success Pittsburgh Regional Healthcare Initiative Michigan Keystone Initiative ICUs at 103 Michigan hospitals, 18 months BSIs/1,000 catheter days Overall rate reduction of 66% Overall rate reduction of 68% Months Pronovost P. New Engl J Med 2006;355:2725-32. Muto C, et al. MMWR 2005;54:1013-16
Lessons Learned from Pittsburgh and Michigan Experience • Decreases in BSI rates in hospital ICUs of varying types • Prevention practices utilized during these interventions were not novel • Practical strategies identified that can be successful across many facilities
If Expanded Nationally…. • 66% reduction of BSIs would translate into: • 180,000 fewer BSIs • 20,000 fewer BSI-associated deaths • $4–6 billion in healthcare cost savings
