CHALLENGES IN THE PREVENTION AND MANAGEMENT OF HEALTHCARE-ASSOCIATED INFECTIONS

Changing population of hospital patients Increased severity of illness Increased numbers of immunocompromised patients Shorter duration of hospitalization More and larger intensive care units Larger step-down units

Growing frequency of antimicrobial-resistant pathogens Lack of compliance with hand hygiene and other

infection preventive measures (e.g., endoscope)

CHALLENGES IN THE PREVENTION AND MANAGEMENT OF HEALTHCARE-ASSOCIATED INFECTIONS

Limited infection prevention resources Implementation of bundles demonstrated to reduce HAIs Public reporting of HAIs CMS non-reimbursement for HAIs Health insurance reimbursement tied to quality goals State and federal laws legislating care issues

Influenza immunization for staff MRSA screening of patients and staff

Greater emphasis on infection prevention by The Joint Commission

Hand Hygiene Adherence an Institutional Priority

Multidisciplinary Program Administrative support (IOC, Executive Staff, Dept Heads) Monitor HCWs adherence to policy and provide staff with

information about performance Provide HCWs with accessible hand hygiene (HH) products

to include alcohol based hand rubs Education regarding types of activities that result in hand

contamination and indications for hand hygiene Reminders in the workplace (e.g., posters) Considering ways to include HH in management standards (loss

of hospital privileges, tickets for non-compliance, coffee coupons)

GI ENDOSCOPES

Widely used diagnostic and therapeutic procedure Endoscope contamination during use (109 in/105 out) Semicritical items require high-level disinfection minimally Inappropriate cleaning and disinfection has lead to cross-

transmission In the inanimate environment, although the incidence

remains very low (35 cases of transmission from 1993-2002), endoscopes represent a risk of disease transmission

TRANSMISSION OF INFECTION

Gastrointestinal endoscopy >300 infections transmitted 70% agents Salmonella sp. and P. aeruginosa Clinical spectrum ranged from colonization to death (~4%) Number of reported infections is small, suggesting a very low

incidence Endemic transmission may go unrecognized

Bronchoscopy 90 infections transmitted M. tuberculosis, atypical Mycobacteria, P. aeruginosa Spach DH et al Ann Intern Med 1993: 118:117-128 and Weber DJ et al Gastroint Dis 2002;87

Page 42: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

ENDOSCOPE INFECTIONS

Infections traced to deficient practices Inadequate cleaning (clean all channels) Inappropriate/ineffective disinfection (time exposure,

perfuse channels, test concentration) Failure to follow recommended disinfection practices

(drying, contaminated water bottles, irrigating solutions)

Flaws in design/manufacture of endoscopes or AERs

Page 43: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

ENDOSCOPE DISINFECTION

CLEAN-mechanically cleaned with water and enzymatic detergent

HLD/STERILIZE-immerse scope and perfuse HLD/sterilant through all channels for at least 12-20 min

RINSE-scope and channels rinsed with sterile, filtered or tap water followed by alcohol

DRY-use forced air to dry insertion tube and channels STORE-prevent recontamination

Surgical Site InfectionSurgical Site Infection

SSIs third most common HAI, accounting for 14-23% of HAIs Among surgical patients, SSIs were most common accounting for

~40% of healthcare-associated infections 67% incisional infections (confined to incision) 33% organ/space infections

Increase an average of 7 days to each hospitalization Increase >$10,000 (2005 $) to each hospitalization Appropriate preoperative administration of antibiotics and other

prevention measures are effective in preventing infection

Prevent Surgical Site Infections:Institute for Healthcare Improvement

Components or “bundle” if implemented reliably can eliminate SSIs Appropriate use of antibiotics Appropriate hair removal Maintenance of postoperative glucose control for major

cardiac surgery patients Establishment of postoperative normothermia for colorectal

surgery patients“Bundle” is a group of interventions related to a disease process that, when executed together

result in better outcomes than when implemented individually.

CHALLENGES IN THE PREVENTION AND MANAGEMENT OF HEALTHCARE-ASSOCIATED INFECTIONS

Health insurance reimbursement tied to meeting quality goals

Incentive package would involve metrics that are clinically meaningful and measurable. Patient satisfaction Ventilator-associated pneumonia, target NHSN Central-line associated bacteremia, target NHSN Hand hygiene, compare to literature Prophylactic antibiotics within one hour of surgical incision

Targeting ZeroD Murphy, APIC 2007

Set goal at zero (BSI, VAP, SSI, MRSA) Strong leadership, MD support, Department champions Use the bundle approach to evidence-based prevention

measures Real-time root-cause analysis when a HAI occurs Personalize HAIs (information about people not rates) Data shared relentlessly with staff, leadership Teamwork essential and team success celebrated Market the value of infection prevention to leadership

MANAGEMENT OF MRSA IN HOSPITALS:IMPACT OF MRSA

126,000 hospitalized patients infected annually 3.95 MRSA infections per 1,000 discharges

>5,000 deaths >$2.5 billion excess health care costs due to MRSA 9.1 days excess length of stay (LOS) >$20,000 in excess cost per case (range, $7,000-

$32,000) 4% in excess in-hospital mortality

MANAGEMENT OF MRSA IN HOSPITALS:5 MILLION LIVES CAMPAIGN (IHI)

Improved hand hygiene Decontamination of the environment and equipment Active surveillance cultures for MRSA colonization

~9.5% admission to UNCHC MICU colonized ~6.5% admissions to UNCHC SICU colonized

Contact isolation for infected and colonized patients Device bundles (Central Line and Ventilator Bundle)

Page 76: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

RATIONALE FOR SCREENING PATIENTS FOR MRSA

Patients colonized or infected with MRSA represent the major reservoir of MRSA in healthcare settings

33% to 91% of colonized patients are NOT detected by routine clinical cultures

Transmission of MRSA from non-isolated patients occurs 16 times more often than from isolated patients

Impact of active surveillance cultures on MRSA acquisitions or infections 16/18 (89%) published articles reported substantial reduction

The Joint Commission2009 Chapter: National Patient Safety Goals

Goal 7-reduce the risk of HAIs Compliance with WHO and CDC hand hygiene Implement evidence-based practices to prevent HAIs

due to multiply drug-resistant organisms Implement evidence-based practices to prevent

central-line associated bloodstream infections Implement best practices for preventing surgical site

infections

Page 79: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

CONCLUSIONS

Healthcare-associated infections are associated with significant patient morbidity and mortality

Implementation of IHI bundles demonstrated to reduce VAP and CR-BSI infections

Compliance with infection prevention recommendations needed to prevent HAIs

New issues: public reporting; CMS non-reimbursement for HAIs; National Patient Safety Goals (TJC); insurance reimbursement tied to quality goals

Page 80: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

CONCLUSIONS

Current challenges Increased emphasis on preventing HAIs; increased

demands on ICP time Lack of compliance with hand hygiene and policies Institution of IHI bundles and other CQI activities Public reporting, mandated vaccines, mandated practices Multidrug pathogens: VRSA, MDR-GNRs, XDR-TB Emerging pathogens: C. difficile, norovirus Public desire for 0 rate of healthcare-associated

infections

Page 81: Challenges for Infection Prevention in the 21 st Century William A. Rutala, Ph.D., M.P.H. UNC Health Care and UNC School of Medicine, Chapel Hill, NC.

CONCLUSIONS

Future Gene therapy-genes introduced into human cells Xenotransplanation-organs from nonhuman species to

human recipients emerged due to shortage of human organs

Emerging pathogens? Influenza pandemic? Bioterrorism?
