3. 3 Case study of St James’s renal unit and the information system Models and diagrams Identifying processes and opportunities for information support Plans for the future Overview

4. 4 Renal pathway - purpose Understand the activity of a renal unit Renal pathway diagram {Want a simple and clear walk through with extra information on the implications for the patient available} {Want a depth of information they can rapidly assimilate} {Want a model that is accurate and unambiguous to identify opportunities for support} Explain the activity of a renal unit GP/other clinical staff Renal expertIT specialist Patient/family member

5. 5 I have modelled areas of St James’s renal unit using the Unified Modelling Language UML syntax helps to make diagrams clear and unambiguous 13 types of diagram 1.Use-case diagrams – show purpose 2.Activity diagrams – like flow-charts Models and diagrams

15. 15 Models can aid understanding by: –Simplifying reality –Making our ideas explicit UML is a particularly useful tool Drill-down example from patients’ needs to staff needs of an information system Generic patterns and variety can be identified Summary

16. 16 To improve the understanding of processes within renal units Examine process variety (e.g. for anaemia management) across different units Compare with outcomes data Identify generic patterns Research solutions from other disciplines Intended PhD – consultation with units and Renal Registry Future work
