100 000 lives campaign objectives december 2004 june 2006
100,000 Lives Campaign Objectives (December 2004 – June 2006)
  • Avoid 100,000 unnecessary deaths in participating hospitals
  • Enroll more than 2,000 facilities
  • Raise the profile of the problem - and hospitals’ proactive response
  • Build a reusable national infrastructure for change

Some is not a number, soon is not a time - Berwick

100 000 lives campaign planks
100,000 Lives Campaign “Planks”
  • Rapid response teams
  • Evidence-based care for acute myocardial infarction
  • Prevention of adverse drug events (medication reconciliation)
  • Prevention of central line infections (Central Line Bundle)
  • Prevention of surgical site infections (correct perioperative antibiotics at the proper time and other elements of the Surgical Infection Bundle)
  • Prevention of ventilator-associated pneumonia (Ventilator Bundle)
campaign field operations
Campaign Field Operations

Introduction, expert support/science, ongoing orientation, learning network development, national environment for change

IHI and Campaign Leadership

Ongoing

communication

Local recruitment and support of a smaller network through communication/collaboratives

NODES (> 55)

*Each Node Chairs 1 Network

Implementation (with roles for each stakeholder in hospital and use of existing spread strategies

FACILITIES (3000-plus)

*30 to 60 Facilities per Network

measurement strategy
Measurement Strategy
  • Change in aggregate hospital mortality, compared to 2004, in terms of “lives saved”
    • Case mix adjustment from three sources, but not yet Hospital Standardized Mortality Ration (HSMR)
  • Direct submission of monthly raw mortality data (deaths/discharges) to IHI
  • Optional data at the intervention-level (e.g., ventilator pneumonia rates, process measures)
100 000 lives campaign results
100,000 Lives Campaign Results
  • Estimated 120,000 lives saved by participating hospitals through overall improvement (IHI cannot attribute change in mortality to the Campaign per se – research studies pending)
  • Over 3,100 Hospitals Enrolled
      • Over 78% of all acute care beds
  • Participation in Campaign Interventions
      • Rapid Response Teams: 60%
      • AMI Care Reliability: 77%
      • Medication Reconciliation: 73%
      • Surgical Site Infection Bundles: 72%
      • Ventilator Bundles: 67%
      • Central Venous Line Bundles: 65%
      • All six: 42%
100 000 lives campaign results7
100,000 Lives Campaign Results
  • Over 55 field offices (“nodes”) and over 130 mentor hospitals
  • Strong national partner support (CDC, AHRQ, Joint Commission, ACC/AHA, etc.)
  • Thousands on national calls
  • Large increase in web activity and downloads of Campaign tool kits
  • Great media coverage (Newsweek, US News and World Report, Wall Street Journal, NY Times)
  • Related campaigns forming nationally and globally (Canada, Australia, Denmark, England)
  • Changes in expectations for care (“getting to zero”) in some participating facilities (many reports of zero ventilator-associated pneumonia or catheter-related BSIs)
success factors
Success Factors
  • Inspiring goal and clear deadline
  • Easy sign-up
  • Minimal reporting requirements
  • Straightforward interventions
  • Optimism, personal motivation, volunteerism
  • Practical direction for hospital leaders
    • Demonstrated link between quality and cost
  • Useful tools
  • Vibrant, distributed national learning network
  • Young, dedicated field team, logistics
5 million lives campaign
5 Million Lives Campaign
  • A campaign against harm (injuries/adverse events)
  • Harm is defined as levels e-i using NCC MERP* Index criteria
    • Level e is temporary harm that required intervention
    • Level i is death
  • Harm is counted…
    • Whether or not it is considered preventable
    • Even if present on admission to the hospital if attributable to medical care

* National Coordinating Council for Medication Error Reporting and Prevention

how did ihi decide on 5 million harms
How did IHI Decide on 5 Million Harms?
  • 37 million admissions to acute care US hospitals annually
    • AHA National Hospital Survey, 2005
  • 40-50 level e-i harms per 100 admissions
    • Chart reviews in 3 hospitals using IHI Global Trigger Tool (GTT)*
  • Therefore, about 15 million harms occur per year (37 million admissions X 40 harms per 100 admissions)
  • If best known results can be replicated, might avoid 3.5 million harms per year = 7 million in 2 years
    • 5 million seemed like a good stretch goal
    • We know that even perfect compliance with all of the planks will not be enough to avoid 5 million harms
  • Further validation of GTT psychometrics pending

5 million lives campaign planks
5 Million Lives Campaign Planks
  • Reduce Surgical Complications – Adopt “SCIP”
  • Prevent Harm from High Alert Medications
  • Prevent MRSA Infections
  • Reduce Readmissions in patients with Congestive Heart Failure
  • Prevent Pressure Ulcers
  • Get Boards on Board
tough questions
Tough Questions
  • IHI claims that organizations need to have leadership commitment, improvement expertise and capacity, and the ability to apply QI methods (rapid cycle PDSAs) – just for starters
  • But contact with many participating hospitals suggests that such capability is not widespread
  • So….are we
    • Encouraging brute force (“hire-a-nurse”) projects to implement a few “planks?” Relying on charismatic champions? ….or….
    • Creating fertile soil for true institutional transformation?
  • How good is the evidence? When is it good “good enough” to spread?
    • MRSA and RRTs: more later

is this remarkable variation due to
Is this remarkable variation due to:
  • Transmissibility and virulence of distinct genotypes?
  • Size, design, or type of hospital?
  • Case mix?
  • Practice variation?
    • Compliance with known, measurable evidence based practices?
    • Less tangible features, such as culture and organization of an intensive care unit?
      • Are nosocomial infections an “expected” consequences of caring for very sick, complex patients, or intolerable, potentially preventable adverse events
        • Vermont Oxford NICQ visits to “best of breed” NICUs

A Modest Proposal…
  • Improve reliability of basic infection control procedures
      • Hand hygiene
      • Isolation procedures

Health care is riddled with defects

40-50% compliance with hand hygiene!!??

What happens at Intel…

What happens in Bowling Green…

From the patient’s point of view, it’s “all or nothing”

Reliability science offers robust approaches to reducing defects and harm in health care

levels of reliability
Levels of Reliability
  • Chaotic process: Failure in greater than 20% of opportunities
  • 10-1: 80 or 90 percent success: 1 or 2 failures out of 10 opportunities (no consistent articulated process)
  • 10-2: 5 failures or fewer out of 100 opportunities (process is articulated by front line)
  • 10-3: 5 failures or fewer out of 1000 opportunities
  • 10-4: 5 failures or fewer out of 10,000 opportunities

Blood banking and anesthesiology alone achieve

the higher levels of reliability in medicine

reliability in healthcare
Reliability in Healthcare
  • Remember, it’s “all or nothing” – not compliance with each individual component of “best practice”
  • Most institutions do fairly well with individual components of evidence-based practice, but performance drops dramatically when the standard is “all or nothing”
  • We are trying to decrease the “defect rate” and to achieve a reliability of performance to the 10-2 level (at least 95% compliance with the entire package of evidence-based practice)
guidelines v bundles intervention packages
Guidelines v. Bundles (Intervention Packages)
  • Guidelines tend to be long, all-inclusive, and confusing
    • Many potential interventions are supported by some evidence
  • Guidelines are difficult to translate into action and often are ignored by clinicians
  • What if just a few key, actionable interventions, supported by strong evidence, were culled from the guidelines?
what is a bundle
What Is a Bundle?
  • A grouping of best practices with respect to a disease process that individually improve care, but when applied together result in substantially greater improvement
  • The science behind the bundle is so well established that it should be considered standard of care
  • Bundle elements are dichotomous and compliance can be measured: yes/no answers
  • Bundles eschew the piecemeal application of proven therapies in favor of an “all or none” approach
central venous catheter bundle
Central Venous Catheter Bundle
  • Hand hygiene before inserting a catheter or manipulating the system and catheter site
  • Maximal barrier precautions for line insertion
    • Hand hygiene
    • Non-sterile cap and mask
    • Sterile gown and gloves
    • Large sterile drape
  • Antiseptic prep used for catheter insertion as per hospital protocol
    • 2% chlorhexidine supported by evidence (but FDA warning for neonates)
  • Site selection
  • Timely removal

a hand hygiene bundle
A Hand Hygiene “Bundle”
  • Staff knowledge
  • Staff competency
  • Alcohol and gloves available at the point of care
    • Operational, full dispensers providing correct volume of rub
    • At least 2 sizes of gloves
  • Correct performance of hand hygiene + gloves worn for standard precautions
    • Concurrent monitoring and feedback
    • Focus on leaving the bedside
    • Staff accountability
prevent mrsa infection and colonization
Prevent MRSA Infection and Colonization
  • Colonized patients comprise the reservoir for transmission (“colonization pressure”)
  • High rates of MRSA colonization complicate empiric antibiotic therapy (e.g., vancomycin)
  • Colonized patients have a high rate of MRSA infection
    • Nearly 1/3 develop infection, often after discharge
  • Colonization is long-lasting, and patients can transmit MRSA to patients in other health care settings (e.g., nursing homes), as well as to family members
five key interventions
Five Key Interventions
  • Compliance with Central Venous Catheter and Ventilator Bundles
  • Hand hygiene*
  • Active surveillance cultures (ASCs)
  • Decontamination of the environment and equipment
  • Contact precautions for infected and colonized patients

* Especially before contact with the patient and after contact

active surveillance
Active Surveillance
  • Perform active surveillance cultures (ASCs) to detect colonized patients on admission
    • Necessity of ASCs per se in controlling MRSA is controversial – why are we recommending it?
      • “Knowledge is power” – clinical cultures miss many colonized patients and vastly underestimate the magnitude of the problem
        • Added value varies by institution (Huang SS: JID 2007;195:330-8)
      • ASCs on admission, followed by testing weekly and/or at discharge, is necessary to document the extent of transmission and the success of control measures
      • Nose +/- perineum/axilla +/- rectum and skin lesions/broken skin
      • Successful programs combine ASCs with reliable implementation of other interventions
    • Controversy regarding ASCs for high-risk areas (ICUs) vs. entire hospital
evidence for ascs
Evidence for ASCs
  • European experience
  • Control of nosocomial MRSA outbreaks
  • Mathematical models
  • Observational studies from individual hospitals
  • Interrupted time series study
  • Cluster randomized trial

the case of rapid response teams
The Case of Rapid Response Teams
  • “Early trials of medical emergency teams suggested a large potential benefit – to the point that some observers regarded further study as unethical. However, a large, randomized trial subsequently showed that medical emergency teams had no effect on patient outcomes.”

Auerbach, et al., NEJM 2007:357:608-613

the merit cluster randomized trial
The MERIT Cluster Randomized Trial
  • 23 Australian hospitals randomized
  • 2-month baseline, 4-month preparation period, 6-month intervention
  • Superb statistical analytic plan
  • More inter- and intra-hospital variance than expected, much lower event rate than expected
  • Increased call rate in intervention hospitals, but no effect on outcomes
    • Reduction in mortality in both arms of study
  • Sub-optimal team activation in patients with call criteria

MERIT Study Investigators, Lancet 2005;365:2091-2097

What If….
  • Baseline period was used to adjust power
    • Study would have been “futile”
  • Performance data were fed back in real time
  • QI was encouraged to improve performance
  • Mixed methods were used to understand context and outcomes in individual sites

Lessons
  • Every QI “experiment” should use the most appropriate evaluation method for the question and context
  • The broadest possible palette of methods should be utilized
  • No opportunity to learn should be wasted
