Content • Objectives (CDR, ANN, PPADS) • Methodology • Results • Conclusion and Future Work Frize Bariciak Gilchrist Medinfo 2013
Objectives • Collect data from NICU patients in real-time and store in Clinical Data Repository • Adapt our outcome estimation system to processing real-time data • Develop PPADS: A decision-support module for physicians and a module for parents. Frize Bariciak Gilchrist Medinfo 2013
Clinical Data Repository Design • Database uses open source MySQL and Entity-Attribute-Value format + time (EAVT). • Confidential information separated from data for research. • Study ID is used to associate patient ID with research data in an anonymous way Frize Bariciak Gilchrist Medinfo 2013
Clinical Data Repository Frize Bariciak Gilchrist Medinfo 2013
Outcome estimations • Decision Trees and Artificial Neural Network • Estimating Mortality • Using real time data and summary data. Frize Bariciak Gilchrist Medinfo 2013
Methodology • 1. Evaluation of CDR: storage, speed, complexity and pilot survey at hospital (MeMeA 2013) • 2. Outcome estimations Collected 85 million data points from 634 infants in NICU 2010 and 2011 Admission (12 hrs), 24 hrs, 48 hrs 5x2 cross validation approach Pre-processing and ANN analysis • 3. Developed PPADS: Physician module and Parent module Frize Bariciak Gilchrist Medinfo 2013
Results--CDR • CDR was better performing than the single EAV and the Multi-data type in terms of storage space, speed and complexity of query. • Pilot test at CHEO with over 75 researchers and physicians: very positive results. Frize Bariciak Gilchrist Medinfo 2013
Results– Outcome estimation • Best results were obtained with data collected at 48 hours after admission. • Mortality estimations: Specificity of 99 %; sensitivity of 63%; PPV of 73%; and NPV of 98%... which meet our clinician’s expectations. Frize Bariciak Gilchrist Medinfo 2013
Results-- PADS PPADS: Identified criteria and mode of operation Examined standards, applied IPDAS Usability 8 parents and 5 neonatologists with very positive results. Frize Bariciak Gilchrist Medinfo 2013

Conclusion and Future Work • CDR design de-identifies data automatically, uses opens-source tools and easy to collect, store, and retrieve data. • ANN performs better than Decision Trees; expanding to predict other outcomes (Length of stay, duration ventilation, IVH, BPD, NEC, ROP) with alerts. • Future work: add input variables to improve performance. • Add warnings and alerts and perform usability study. • PPADS well received by physicians and parents • Next phase: parents of infant who died; then randomised clinical trial with parents of babies in NICU • More types of decisions will be added.
