1. Handheld-Based Decision Support in Trauma Medicine Blaž Zupan Faculty of Computer Science, University of Ljubljana Baylor College of Medicine, Houston

2. Examples of Medical Decision Support Probability of recurrence after radical prostatectomy Predicting patient’s long term clinical status after hip arthroplasty Wrist injuries: should we operate?

3. Why? Second opinion Systematic approach Decision analysis –which factors are important –how do they influence the decision Prognosis, Treatment planning, Diagnosis,...

4. Why handhelds? Handhelds are practical Decision support tool should be available wherever decision takes place They provide enough computing power

5. Decision Support Models background (expert) knowledge data (EPR, clinical data bases,...) statistical analysis data mining decision support model patient’s data decision (prognosis, diagnosis, treatment plan,...)

6. Sucess Story: Prostogram MW Kattan, P Fern: From 1999 in regular use at Memorial Sloan-Kettering Hospital and BCM

7. Decision Support Shell on Palm (TM) statistical analysis data mining decision support models in XML (synchronization) decision support

8. An example... Aoki N. et al: Mathematical Analysis of Data from the Hanshin- Awaji Earthquake.

9. ... An example

10. Current Status Applications –BCM & Ben Taub Hospital, Houston: traumatology –Smrke (Clinical Center in Ljubljana, Slovenia): hip, wrist injury –Kattan (Sloan-Kettering, NY): prostate cancer Methodology –Logistic regression, other methods (table lookup, naive Bayes, survival models) coming soon –Integration with data mining tools coming soon
