  1. AIS Development of an anesthetic information system VUmc Amsterdam H.H. Ros N. van Schagen K. Gigengack A. van Dusseldorp

  2. AIS • Time and Money: 1985 • Multichannel data acquisition • Renewal anesthetic equipment • Philosophy • Structure • Demands • Implementation • Demonstration

  3. AIS - History • Separate units for each monitoring function • High number of single units • Different Manufacturers • PDMS: not existing or adapted to specific hardware • “Total Design” systems • Hardware and Software mutual dependent • Simple and not structural output (analog / RS232 ) • Changing setup

  4. AIS - History II • Equipment central in development • IT – development neglected / rejected • No standardization • Of software • Of interfaces

  5. AIS – History III • Limited functionality • Number of signals / parameters • Methods of sampling fixed • Information transfer fixed • All equipment different (interface) protocols

  6. AIS – History IV • Alarm strategy not standardized • Depending the manufacturer • Systems not flexible • New development = buying new system • Each OR an own / separate system • Limited role of the anesthesiologist

  7. Situation before development AIS Patient Monitor(s) Anesthetic Equipment Anesthetics Drugs etc Display/control Display/control Display/controle Anesthesiologist Outside World

  8. AIS – Concepts • Information System – ” Information Brains” • Efferent stream of data • Afferent stream of data • Data acquisition – full disclosure • No discussions about the dataset • All parameters will be recorded (if possible) • The chosen filter will display what is needed or wanted. • Processing data in IS independent of recording

  9. AIS – Concepts II • Transducers outside IS • Intelligence in IS: • Feedback to anesthesiologist • Individual adaptation of alarms, performance of IS system subject to users • Standard human interface

  10. AIS – Open System Architecture • Constructed for several hardware platforms • No dedicated software for communication and data acquisition: • Standard commercial software / freeware • Direct connections to the outside world • Full disclosure possible • Plug and Play • Worldwide standard supported • Simple maintenance with easy access - standard technology • Automatization considered as a process

  11. AIS – OUTSIDE WORLD • Libraries – digital support systems • Laboratories • Other OR’s / wards • Hospital information system • Decision support / expert system • Management support • Quality assurance • Medical Audit • Reports –including anesthetic chart • Research • Education and training • Internet etc • Servers for recorded data.

  12. AIS- implementation • Use of existing hardware • Use of existing software • Afferent data acquisition • Full Disclosure • No operating of equipment - efferent • If possible standard available software

  13. Situation before development AIS Patient Monitor(s) Anesthetic Equipment Anesthetics Drugs etc Display/control Display/control Display/controle Anesthesiologist Outside World

  14. Situation after implementation of the AIS Patient Monitor Anesthestic equipment Anesthetics, Drugs Information system Information system Display/control Display/control Display/control Anesthesiologist Communication Outside world

  15. Monitor Anesthetic Equipment Other recording possibilities: Infusion pumps, ECC, WEB-devices Information system: AIS Outside World: Patient ID and data Preoperative assessment data Pharmacy – reference Bloodgasanalyzer HL7 General terminal: web, mail, medicating system Report generators (web based) Anesthetic List as web application Display and control Planning, Pharmacy, Waiting list, Clients Operation Complex, Management, Upload to Hospital Information System, DB of operations
