According to the Leapfrog Group, hospitals in the US pay a surcharge of $5900-$7800 per admission to cover a wide range of medical errors. Smart point-of-care systems address the source of these errors to help reduce healthcare expenditures while improving patient care. The systems reliably connect and transmit critical data for medical devices, clinicians and patients – ensuring information is shared exactly when and where it's needed most.

However, it is extremely challenging to address data interoperability, safety, security and integration with other systems in today's healthcare environment. As data volume grows and becomes increasingly valuable, these issues will affect system and data architecture, especially with the rise of smart analytics used to improve the quality of treatment. Join Tracy Rausch, founder and CTO of DocBox Inc., and Sumeet Shendrikar, RTI Solutions Architect, as they discuss the challenges of developing smarter point-of-care systems and how a data-centric architecture can ensure the right data gets to the right place at the right time to improve patient healthcare.

  • 4. It’s All About the Data “Health care is burdened by a system where doctors and caregivers have to go searching for vital information; it is inefficient at best and life threatening at worst. We need to make the data more intelligent and integrated, more predictive and proactive, so information finds the doctor instead of the other way around. Intelligent data flows speed up care delivery and can prevent chronic conditions by getting the treatment right the very first time. Similarly, in terms of health management costs, “intelligent” hospitals are deploying systems that behave like air traffic control for medical staff and devices, and provide a full detailed view of hospital resources. Better utilization cuts capital expenses. Better asset location leaves nurses more time to focus on patients. Better management improves patient flow, cuts operating costs, and saves hospitals millions.” - Jeff Immelt (Nov 2012)
  • 5. Connecting the Data Need to construct the “Data Graph”
  • 6. RTI Connext: Distribute the Data Real-Time Analytics & Control Operator HMI Sensors Actuators IT and/or Cloud Integration
  • 7. RTI Connext: The Software DataBus™ • Data centric – Structured, accessible data – Like a database for moving data • Independent modules – Supports SOA • Plug and play flexibility – Like a hardware bus • Peer-to-peer performance – Like streaming protocols • Standards-based interoperability – Like TCP/IP • Abstracts Location RTI Connext DataBus™ Scalable, high- performance, reliable infrastructure that eases integration
  • 8. Why a DataBus Transport? • Connects quickly, easily, powerfully • Reduces risk – Proven, reusable, certified • Saves money – Decouples large problem into solvable pieces • Enables advanced capability – Reliability: redundant, 24x7 operation – Performance: microsecond latency, megabyte throughput – Integration: Any transport, OS, language RTI Connext DataBus™
  • 9. RTI Connext: Building Blocks RTI DataBus Peer-to-peer: • Superior for real-time & near real- time delivery Integration Services to connect system-of- systems RTI DataBus R RTI DataBus R R R R R R R Integration Services can be composed into a hierarchical topology

  • 13. Remote Monitoring 4G/LTE Connecting devices with hospitals to provide better treatment while en-route
  • 14. Machine Command/Control • Mevion’s Proton- Beam Radiation Therapy system zaps tumors with accelerated protons • The treatment must be continuous for 30- 40 days; downtime endangers treatment success • Mevion’s PBRT delivers dependable treatment at low cost
  • 15. Data Acquisition • RTI powers Varian’s NMR and MRI product lines • Any one of the sixteen MRI receivers can saturate a 1Gbit network. • RTI controls and optimizes network use to handle megabytes of load without losing data“RTI delivered great functionality at a low cost. Using RTI middleware saved us a lot of money, time, and effort compared to our previous in-house developed solution.”
  • 16. Device Interoperation • The Integrated Clinical Environment (ICE) standard specifies interoperability for medical devices • All ICU & operating room devices — from blood pressure cuffs to intravenous pumps to ventilators — could be interconnected according to the ICE standard – Complete logging – Automatic error detection – Better care • The DDS standard and RTI middleware enables plug & play interoperability across manufacturers
