Changes to the ICU protocol
Request of European Commission:
– Structure and process indicators of HAI prevention
– HAI mortality data
Process for identification of prevention indicators:
– Meeting HAI-Net ICU Network, Oct 2013
– Smaller expert meeting, February 2014
– HAI-Net Coordination Committee, May 2014
– Teleconferences HAI-Net ICU expert group
– Consultation of Infection Section of ESICM (Oct 2014)
http://ec.europa.eu/health/patient_safety/healthcare_associated_infections/index_en.htm
Council Recommendation of 9 June 2009 on patient safety, including the prevention and control of healthcare associated infections (2009/C 151/01)
ECDC PPS in acute care hospitals, 2011-2012: structure and process indicators
Infection prevention and control indicators in 2011-2012: single bed rooms, alcohol hand rub consumption
Mapping leads to action: e.g. measures to improve AHR data availability in UK-Scotland
Percentage of beds in single rooms Alcohol hand rub consumption

ECDC PPS in acute care hospitals, 2011-2012: structure and process indicators
Two indicators of infection prevention and control staffing
Mapping leads to action: e.g. Czech Republic: National HAI Reference Centre (2012), new IPC guidance (2013)
IPC nurses (FTE/250 beds) IPC doctors (FTE/250 beds)
Infection prevention and control indicators: objectives Increase awareness for HAI/AMR prevention through
surveillance/repeated PPS
Add local value to surveillance by inter-hospital comparison and follow-up of key preventive measures (=> increase participation to surveillance networks?)
Inter-country comparison and follow-up of implementation of key preventive measures in EU/EEA countries
Follow-up of implementation of ECDC guidance and Council Recommendation 2009/C 151/01
At the longer term: linking evolution of prevention indicators with outcome indicators trends

- Capacity/Preparedness

HAI-Net ICU structure and process indicators
1-2 weeks data collection & aggregated reporting per year/surveillance period, Unit based (aggregated), at least 30 opportunities per indicator
Current proposal:
– Hand hygiene: alcohol handrub consumption (L/1000 pt days) in ICU
– ICU staffing: registered nurses and nurse aides
– Antimicrobial stewardship: systematic review of AM after 48-72 hrs
– IAP prevention: cuff pressure control, oral decontamination, patient position
– CR-BSI prevention: CVC maintenance – dressing observation and/or clinical surveillance of insertion site (chart review)
Forms: hospital/ICU data 1/2

HAI-Net ICU other protocol changes: attributable mortality HAI-related mortality, direct measurement of relationship of HAI to
death:
– Measured at HAI data level (Light and Standard protocol)
– In addition to statistical approach for countries with patient-based (standard protocol) data
– Proposal: for each patient with HAI, record outcome:
No death in ICU Death in ICU, HAI definitely contributed to death Death in ICU, HAI possibly contributed to death Death in ICU, no relationship to HAI Death in ICU, relationship to HAI unknown/ not verified
Methodology:
– Algorithm/cause analysis in ICU by clinician(s) and/or ICP?
– Consider: expected death on ICU admission/SAPS II score/McCabe score, other causes of death, active (complication of) HAI at time of death, antimicrobial resistance, appropriateness of treatment
HAI-Net ICU other protocol changes
Removal variables standard protocol (too many missing data):
– date of hospital admission
– coronary care
– previous surgery site
– parenteral nutrition
Change APACHE II in “Other severity score type” (APACHE II, SAPS III, McCabe, MPM …) and “Other severity score value”
Antimicrobial resistance data:
- request to change markers from ‘non-susceptible’ to ‘resistant’ (no change for ICU protocol – S/I/R/U collected)
- colistin (+tigecycline?) for Enterobacteriaceae, remove ESBL (only keep C3G), remove AMC?
- add PDR (pandrug-resistance)? (no PDR – possible PDR – confirmed PDR – Unknown)
