Purpose MRSA Burden
Over 126,000 persons are infected by MRSA in hospitals annually
~ 4 MRSA infections per 1,000 hospital discharges Over 5,000 die as a result of these infections Over $2.5 billion excess healthcare costs
On average, for each MRSA patient this means: 9.1 days excess LOS Over $30,000 in excess cost per case (range $30,000-60,000) 4% in excess in-hospital mortality
1/3 patients acquiring MRSA will become infected.

Consistent Use of Known Practices Work Target Modes of MRSA Transmission
Person-person via hands of health care providers
Personal equipment (e.g., stethoscopes, PDAs) and clothing

RN awareness of MRB status increased from 24% at baseline to 59% at 1 year. -93% at 1 year after notifying nurses.
Implementation of isolation precautions increased from 15% at baseline to 51% after 1st intervention and then to 90%.
RI electronic tool notifies staff of MRSA positive history at Wishard, based on micro data from all Indy hospitals (except VA).
286 unique patients generated 587 admissions (4,335 inpatient days) where receiving hospital unaware of the prior history of MRSA.
An additional 10% of MRSA admissions received by project hospitals over one year and over 3,600 inpatient days without contact
isolation. Cac et al Arch Intern Med. 2007;167(19):2086-0Kho et al J Am Med Inform Assoc 2008; 15:212-216

Implementation “Testing Techniques to Radically Reduce
Antibiotic Resistant Bacteria (MRSA)”
AHRQ funded Indiana ACTION Team effort over 18 months through the ACTION collaborative funding mechanism
Our interventions are based on the Pittsburgh model as specified by AHRQ: conduct active surveillance of all incoming pts.
in ICUs improve rates of contact isolation Improve hand hygiene rates

Two ICU units in 3 original hospital systems St. Francis (two ICUs in South Hospital) Clarian (Methodist and University Hospital) Community (Community East and Heart
Hospital) Early success encouraged 3 remaining
systems to join the project Wishard (two ICUs) VA Medical Center (housewide) St. Vincent's (two ICUs in north facility)

• Our health care engineers partner with and train front-line workers to use lean-six sigma and positive deviance approaches
• Focus on coaching front-line staff teams to lead instituting systems changes to systematize processes and sustain practices.
• Emphasize regular measurement and feedback of adherence to enhance adoption.
• Weekly Meeting of all hospital teams to identify barriers & facilitators, review and reinforce progress, share best practices, strategize about spread and solutions.

Preliminary pre and post intervention results for first three hospitals suggest average of 60% reduction on study units
~ 20% reduction hospital wideCurrently investigating optimal
biostatistical approach such as time series analysis to confirm

Infection control is a regional problem, requiring a coordinated effort
Created a citywide electronic notification system to prospectively track all known patients with MRSA
Currently track 17,000 patients with a history of MRSA infection or colonization across Indianapolis.
Since May 2007, delivered 2698 admission alerts on patients with a history of MRSA, 19 percent based on data from another institution.
20 infection control providers (ICPs) spanning 16 hospital

System redesign approach of training, consultation and coaching front-line staff seems to be strong, sustained approach
Importance of buy-in from highest institutional levels crucial
Enthusiasm builds from within because redesign teams own it!
Informatics tool helpful in identifying great cross-over of MRSA patients in hospitals
![Page 14: Purpose MRSA Burden Over 126,000 persons are infected by MRSA in hospitals annually](https://reader033.vdocuments.us/reader033/viewer/2022051401/56815580550346895dc34d54/html5/thumbnails/14.jpg)
Our proposed data collection too intensive for most community hospitals
Need a better electronic data collection infrastructure relating to outcome data
Hospitals desire regular feedback on impact of interventions
Little time for paper writing (Hazard of short time lines for funding)
![Page 15: Purpose MRSA Burden Over 126,000 persons are infected by MRSA in hospitals annually](https://reader033.vdocuments.us/reader033/viewer/2022051401/56815580550346895dc34d54/html5/thumbnails/15.jpg)
Engagement Process: The engagement process involves multiple social change processes centered on PD.
Outcome Data Feedback: Transmission and infection rates are shared with staff.
Process Data Feedback: Nursing unit staff track performance on infection control practices.
![Page 16: Purpose MRSA Burden Over 126,000 persons are infected by MRSA in hospitals annually](https://reader033.vdocuments.us/reader033/viewer/2022051401/56815580550346895dc34d54/html5/thumbnails/16.jpg)
Learning Collaborative: Teams from hospitals connect with teams from other hospitals employing the MRSA Intervention Bundle to foster learning and innovation.
More extensive activities to train interdisciplinary teams within each of the participating health systems (compared with first study).
