“Nosocomial” Infections

  • Nosocomial Infections

    • Not present or incubating upon admission to the hospital (48hr rule)

  • Preferred: Hospital Acquired Infections (HAIs)

  • 5-10% of patients admitted to hospital or 2 million patients

  • 88,000 deaths per year

  • Costs exceed 4.5 billion/year

  • 1 outbreak per 10,000 discharges


From a public health issue to a very public issue
From a public health issue to… A very public issue


On the horizon for us
On the horizon for us

  • Texas reporting

    • Law passed requiring mandatory reporting of HAI to TDSHS starting 2008

    • Rates will be publicly available

  • Federal reporting

    • Bill introduced requiring mandatory reporting to CDC through NHSN

    • New national guidelines on infection control 2008

  • Medicare

    • SCIP as core measure

    • Lower rate reimbursement for patients with HAI starting 2008


VAP

  • Leading cause of death amongst hospital-acquired infections

  • Mortality 46% compared to 32% percent for ventilated patients who do not develop VAP

  • Increased ventilator days

  • Increased ICU LOS


Vap defined
VAP defined

  • Patients mechanically ventilated for greater than 48 hours

  • Exhibit at least 3 or 5 following symptoms:

    • Fever

    • Leukocytosis

    • Change in sputum (color and/or amount),

    • Radiographic evidence of new infiltrates

    • Worsening oxygen requirements CDC 2003

VAP prevention

“Vent Bundle”

  • Suctioning

  • Head of bed > 30o

  • Oral care

  • “Sedation holiday”


Memorial hermann micu
Memorial Hermann -MICU

  • 16 bed unit admitting 1100 patients per year

  • 60% ventilated >3 days putting them at greater risk for VAP

  • Chief diagnoses include septicemia, respiratory failure, HIV/AIDS, renal failure, and multisystem organ failure secondary to multiple co-morbid conditions

  • Previous improvement work had made respectable reductions in VAPs from 2-3 per month to <10 per year, however it was felt more was achievable


Aim and measures
Aim and Measures

Aim

To reduce VAPs in the MICU to Zero within six months.

Measures

  • Reduction in number of VAPs per 1000 ventilator days

  • Increased compliance with all aspects of the ventilator bundle.



Interventions education
Interventions: Education

  • MICU “Huddles” on VAP and mortality

  • Posted rates in the unit for staff and MDs to see

  • Posted rates in public areas for patients and family members to see

  • Reviewed bundle compliance regularly in multidisciplinary team meetings

  • Reviewed compliance and VAP rates at local and system critical care committees


Interventions implementation
Interventions: Implementation

  • Developed physician Rounding Tool to address VAP bundles

  • Appointed unit champions to assure patients were out of bed on daily basis

  • Formalize oral care process using chlorahexadine

  • Trained Patient Care Assistants (PCAs) in oral care

  • Mandated that oral care be a shared responsibility by RNs, Respiratory Therapists and PCAs increasing oral care from 4 times per day to 10 times per day

  • Computerized reminder alert for the care team

  • Located all oral care supplies near ventilators

  • Located isolation supplies –gowns, gloves, masks at entrance to every patient room


Interventions implementation1
Interventions: Implementation

  • Increased isolation practices for all infected patients to include booties, head coverings

  • Implemented glycemic protocol to keep glucose between 80 and 150

  • Implemented automatic insulin drip for all patients who had 2 consecutive finger sticks above 150

  • Implemented standardized sedation protocol

  • Improved Sedation holiday practices by team approach to assessment

  • Improved transportation practices


Interventions audits
Interventions: Audits

  • Implemented daily manager rounds to assure bundle compliance

  • Assured compliance with unit protocols by PRN staff and consulting MDs

  • Implemented a mini-RCA process for all VAPs to detect specific patient characteristics and system risk factors

  • Infectious Disease Dept conducts random weekly audits for bundle compliance

  • Infectious Disease Dept reviews all cases to diagnose VAPs based on CDC criteria


Results bundle compliance
Results: Bundle Compliance



More to do fmea
More to do: FMEA

  • Aspiration during transport

  • Cuff leaks

  • Unplanned extubations requiring reintubation


Results: VAP Rate


Results overall
Results: Overall

  • VAP rate went from 8-12 per year to zero within three months.

  • No VAPs have occurred in the MHH-TMC MICU for 26 consecutive months

  • Compliance with all aspects of the VAP bundle is between 98 - 100%.


Results cost savings
Results: Cost Savings

  • A financial analysis completed by our infectious disease and financial departments concluded that a VAP in any of our ICUs adds $57,000 in additional costs for additional antibiotics, ventilator time and ICU stay.

  • Cost avoidance for this project based on avoiding 8 VAPs per year is $456,000.


Sustainability
Sustainability

  • Takes a Village to raise a “Zero”

    • Culture Changed

  • Goal became Expectation

  • Work flow changes became routine

  • Reporting of “near misses”

  • Created a highly functioning multidiciplinary team


Conclusions and next steps
Conclusions and Next Steps

  • With concerted and focused effort “zero” is possible as an outcome.

  • As with any major improvement, the challenge is to maintain this level of performance.

  • Build on this methodology to achieve similar improvements for other hospital acquired infections in the Intensive Care Units.
