QoS and QoE for medical applications

  1. 1. Multimedia Conferencing in Healthcare:Multimedia Conferencing in Healthcare: QoS requirements and QoE expectationsQoS requirements and QoE expectations Katarzyna Wac, Muhammad Ullah, Markus Fiedler, Richard Bults QoE/QoS ETSI meeting France, 21-22 Sept 2010
  2. 2. outline • specifics of healthcare domain • multimedia conference for healthcare • lacks of standards • fragmentation of QoS requirements and QoE expectations • conclusive remarks Katarzyna Wac, Carnegie Mellon University
  3. 3. consultation compliance education/ disease/epidemic outbreak trackingapplications application/technology providersstakeholders healthcare healthcare treatment Katarzyna Wac, Carnegie Mellon University diagnosis treatment monitoring education/ promotion different requirements for emergency/non-emergency case patients healthcare professionals/organizations insurance companies regulatory/ governments treatment prevention of illness
  4. 4. healthcare domain trends affordable health for everyone older society unhealthy lifestyle chronic diseases episodic cure continuous care patient empowerement & continuous efficient effective healthcare self-management Katarzyna Wac, Carnegie Mellon University chronic diseases high cost centralized continuous efficient effective healthcare (distributed) healthIT/eHealth multimedia conference tools
  5. 5. multimedia conference scenarios under-staffed providers to timely diagnosis from remote specialist Katarzyna Wac, Carnegie Mellon University under-staffed providers to patients residing in rural areas, Tribal lands and health professional shortage areas pandemic situations – assist more patients, avoid them to use public areas real-time treatment e.g. decision to deliver the life-saving, clot-busting drug known as tPA within 3 hours of stroke onset [Knox, 2009]
  6. 6. lack of standards & ETSI timeplan 2 years • healthcare services classification • interoperability, also with legacy devices • patients safety • radio interfaces and RF inference • security and privacy, role-based authentication and authorization Katarzyna Wac, Carnegie Mellon University 5 years • asymmetry of links • dependability • standards and protocols for sharing administrative, research and clinical data 10 years • context-awareness heterogeneity of requirements…
  7. 7. healthcare data file sizes Katarzyna Wac, Carnegie Mellon University
  8. 8. required broadband connectivity Katarzyna Wac, Carnegie Mellon University
  9. 9. ex. multimedia conference reqs tele-monitoring ECG, X-rays, video and high resolution still images [Qiao] e2eD: ECG 12 ms, X-ray 60s, image 5s AV, ECG, HR, BP, SpO2, images, EHR [Martinez] e2eD: audio 150 ms loss 10%, video 250 ms, 12% remote hospital WWW, EHR, image, VoIP, vital sign, video, equipments control [Soomoro] e2eD: vital signs 300ms, video 10- 250 ms, control 3-5 s Katarzyna Wac, Carnegie Mellon University tele- ultrasonography ultrasound, robotic arm control data [Grawi] e2eD 325 ± 297 ms, loss < 0.5 %; 5 fps tele-surgery AV, robotic arm control data [Marescaux] ‘safe’ e2eD 330 ms tele-trauma images, video, ECG [Chu] low delays, no loss for ECG, frame resolution: 320x240 AV, medical data [Navarro] video H.263 5-10 fps, audio AMR 4.47-12.2 kbps, data 5-10 kbps voice, AV, ECG, images [Gallego] e2eD: AV 150-400 ms, ECG 1ms
  10. 10. conclusive remarks • specificity of health care domain • potential of multimedia conference tools • no standards • fragmented QoS/QoE requirements space • need for reimbursement schemas, change in clinical processes • lack of close collaboration with healthcare practitioners: user acceptance is a critical factor Katarzyna Wac, Carnegie Mellon University critical factor – instate standards during the infancy and development of solutions, before problems arise – listen rather than impose Five Rights of Medication Safety right patient right drug right dose right time right route Five Rights of healthIT right device right interface right distribution right content right intelligence
