Title: Prevention of BSI and VAP Measuring Change in Outcomes Part I
1Prevention of BSI and VAPMeasuring Change in
OutcomesPart I
2NNIS Surveillance Data
- Central line-associated BSI rate
- 5.0/1000 central line-days
- Ventilator-associated pneumonia rate
- 5.8/1000 ventilator-days
- The numerator is the number of events
- Number of patients with infection or pneumonia
- The denominator is the number of central-line or
ventilator days, standardized to 1,000 - Census data in the ICU, all patients with lines
or on ventilator - NNIS rate is calculated as number of BSI or VAP
events (numerator) divided by observed number of
line or vent days for the ICU (denominator) times
1,000
3Characteristics ofNNIS Rate Data
- Requires aggregating data over a large sample
- Takes time to accumulate data
- Appropriate for Surveillance or Quality assurance
- Appropriate for detecting a rate increase
- Not appropriate for detecting a rate decrease
unless sample is huge - Insufficient for Quality Improvement
4Statistical Process Control Charts
- Used in QI to detect improvement (did it work?)
- Chart
5BSI Rates and Control Chart
- Excel Tool
- Naming and Saving the File
- Entering Baseline Data
- Setting the Baseline Period for the Control Chart
- Editing Chart and Printing
