A Bucket Full of Numbers? An Insight to Hemodialysis Data Management Systems Kevin Lyons Fresenius Medical Care, Bad Homburg / Germany
Topics Evolution of Hemodialysis Data Management SystemsEvolution of Hemodialysis Data Management Systems Potential PitfallsPotential Pitfalls A case for automatic data acquisitionA case for automatic data acquisition The Current ‘State of the Art’The Current ‘State of the Art’ –What should a modern IT system provide? What about the future?What about the future?
Evolution… The early days….The early days…. –Paper record. -Only option available. -Manual. -Difficult to evaluate trends. -Prone to tpyographical error. -Very short term use. -Limited contribution to patient care.
Life Cycle of the Paper Record
Evolution over 25 years Number of Patients Treatment time hours per week 9-12 hours per week Dialysers Hollow fibre just a prototype Hollow fibre dominates QB/QD /500 Up to 500/800 DialysateAcetateBicarbonate Dialysate delivery CentralIndividual Volume control Kuf and TMP Volumetric Staffing Few actions required Multiple complex actions Machines Relatively simple Highly complex with physiological or bio-feedback ReimbursementStraightforward Increasingly complex Computers Mainframes and Character terminals PC’s with Pentium processors Adapted from Ronco C 2000
A case for a Database? A dialysis unit may collect several GB of data per year Device & machine data Pressure, conductivities, flows, temperatures, physiological data Other treatment information Symptoms, access documentation, hospitalizations … Laboratory results Diagnosis Demographic information Drug prescription & intake Reference data (medications, diagnosis catalogues, …) It is hard to store/maintain this information without databases
COMPUTERISE! Driving Forces towards Data Management Downward pressure on healthcare costs Steady increase in patient numbers Compliance to Standards E.g. DOQI Keeping abreast of technology Desire to become paperless Optimisation of Resources Sheer Volume of data to manage Sharing & Exchange of information
Industry Responds….. Sample for illustrative purposes only
Evaluation of Clinical Computing Systems as Used by DOPPS Participants Nurse Medical Manager Director Nurse Medical Manager Director Pleased with current system41%34% Need to add additional functions75%73% Need a new system45%55% Current system is very good at Patient care….37%33% Current system is very good at Monitoring quality and outcomes44%38% Sargent J 1999
Factors Limiting the Effectiveness of Computer Systems Purchasing system before needs are defined System does not meet the requirements Data collection and entry Management of collected data is complex Lack of a friendly interface Reporting not targeted to improving patient care levels Not upgradeable Lack of an ongoing training program / poor training Adapted from Ronco C 2000
T [°C] t[h] Tven Tbody t[h] E[kJ] … modern dialysis machines are able to provide much more treatment information T [°C] t[h] Tven Tbody t[h] E[kJ] Online plus ™ System
Other Medical Devices Can Provide Information too… …in principle, any device with an RS 232 or similar interface can pass on its measured parameters
The Missing Link… File Servers Workstations

Benefits of a Data Acquisition System Real time treatment informationReal time treatment information Accuracy of recorded dataAccuracy of recorded data –Patient reported –Typographical Therapy given based upon patient statusTherapy given based upon patient status Burden of data collection greatly reducedBurden of data collection greatly reduced Facilitates Audit and AnalysisFacilitates Audit and Analysis
Acquisition alone is not enough… It can only be successful when implemented with the ‘right’ database.
What Characterises an Outstanding Data Management System? FunctionalityFunctionality –Data presentation & analysis –Integration of dialysis machines & medical devices -Advanced features (decision support, bio-feedback) –Integration with other systems
What Characterises an Outstanding Data Management System? Acceptance: The user likes to work with it, …Acceptance: The user likes to work with it, … –Simplicity, usability and workflow –Don’t have to drastically change their way of working –Training Please Confirm F60 With workflow: The work looks for the worker Where do I have to enter what?? Without workflow: The worker looks for the work
Acceptance: Training is an ESSENTIAL element NEVER underestimate the importance of trainingNEVER underestimate the importance of training Create local experts via the TTT conceptCreate local experts via the TTT concept Ensure ALL relevant disciplines are involvedEnsure ALL relevant disciplines are involved Bilateral responsibilitiesBilateral responsibilities
What Characterises an Outstanding Data Management System? Cost effectivenessCost effectiveness –Benefit from changing technologies and competition –Scalability
Cost Effectiveness Profit from competition, be independent ofProfit from competition, be independent of –Platform (AS400, PC, SUN, …) –Database (DB2, Oracle, MS-SQL, …) –Operating System (OS400, NT, Win9x, Solaris, …) Profit from changing Telecoms market, chooseProfit from changing Telecoms market, choose –LAN, Frame-Relay, Internet, Dial-up, … Profit from global developer community and use open and (license) free standardsProfit from global developer community and use open and (license) free standards –Java, HTML, XML, Servlet, Internet (www, ftp, …)

Internet….. What’s so Special? For the very first time in history we have: – –Option to share information and to communicate without any restrictions by borders and locations - -Send: text (letters), pictures (x-ray), movies (echo), sounds - -Discuss: chat-rooms, news-groups - -Retrieve information: on-line databases & journals – –Standardised technology – –Chance to share common data: consistent, non-redundant, without lavish interfaces, shared by larger community, e.g. Several clinics – –Affordable by nearly everybody For the very first time in history we have: – –Option to share information and to communicate without any restrictions by borders and locations - -Send: text (letters), pictures (x-ray), movies (echo), sounds - -Discuss: via chat-rooms, news-groups - -Retrieve information: on-line databases & journals – –Standardised technology – –Chance to share common data: consistent, non-redundant, without lavish interfaces, shared by larger community, e.g. Several clinics – –Affordable by nearly everybody State-of-the-art clinical IT systems have to utilize these opportunities!
