EPIC Evidence-based Practice Identification and Change Past, Present, and Future Shoo K. Lee, MBBS, FRCPC, PhD Director, Canadian Neonatal Network Scientific Director, iCARE Professor of Pediatrics, University of Alberta EPIC/PHSI Training Workshop November 9 & 10, 2006 Toronto ON Presentation Objectives Overview how EPIC evolved Describe the science behind EPIC Describe future EPIC plans Background Continuous Quality Improvement (CQI) methods have been investigated for reducing bronchopulmonary dysplasia (BPD) and nosocomial infection (NI) in the NICU Limitation - existing CQI techniques employ a subjective, uncritical approach to practice change that may not be evidence based How did EPIC Evolve? Problems with traditional continuous quality improvement (CQI) approaches Subjective Not always evidence-based Seldom use data from institutions in question Mostly intra-institutional in nature
Results are not always generalizeable We developed EPIC to improve upon traditional CQI approaches EPIC Objectives To develop a new scientific method for QI EPIC that is: (a) Evidence-based uses published evidence (b) Objective uses data from individual hospitals to identify practices for targeted intervention (c) Collaborative uses a national network to share expertise and experience To test whether EPIC reduces BPD and NI in a cluster randomized controlled trial of Canadian NICUs The Thee Pillars of EPIC 1. Objective Systematic reviews of evidence 2. Quantitative analysis Multi-centre outcomes and practices Identifies practices associated with outcome variation that can be targeted for intervention 3. Utilizes collective multi-disciplinary expertise Infection control, quality improvement, etc Method
Prospective cluster randomized controlled trial 12 NICUs Randomization 6 BPD, 6 NI Each group Control for other Additional controls - 5 other NICUs in CNN that were not participating in the study All infants < 32 weeks gestation were enrolled Definition: (a) BPD O2 need at 36 weeks GA (b) NI Positive Blood, CSF or Urine culture 2 phases (a) Baseline period (1 year) (b) Intervention period (2 years) Funded by Canadian Institutes of Health Research EPIC - Baseline Period (Year 1) Baseline data collection on outcomes and practices Train multi-disciplinary hospital teams Review of published literature Meeting to share findings Identify Critical Care Pathways Qualitative research identify barriers to change Data analysis identify practice differences associated with outcome variation for targeted intervention
Data Analysis to Identify Practices for Targeted Intervention Grouped Data Analysis - compare outcome variations among NICUs - identify non-therapy and therapy related risk factors - estimate the attributable risk of risk factors Individual Hospital Data Analysis - calculate hospital specific incidence rates - identify hospital specific risk factors for targeted intervention - conduct trend analysis using control charts Generalized linear mixed effects model - to adjust results for the cluster randomized design Monte Carlo Bootstrap Simulation - to estimate the 95% confidence limits for control charts Therapy Related Risk Factor for NI - PICC Therapy related risks - central lines, - mechanical ventilation, - parenteral nutrition, - lack of enteral feeding 40% of nosocomial infection associated with central lines
PICC lines carried highest risk Adjusted probability for developing nosocomial infection for PICC lines Line type Risk-Ratio for NI Umbilical catheters 2.0 Broviac cathethers 3.1 PICC catheters 3.5 EPIC Intervention Period (2 Years) Develop practice change strategies Prepare supporting materials NICU staff communication and training Implement practice change strategies Quarterly change cycles
