    • Creating Interoperable Medical Devices that fit into Hospital Enterprise IT Environments By Shahid N. Shah
    • NETSPECTIVE Who is Shahid? • 20+ years of software engineering and multisite healthcare system deployment experience • 12+ years of healthcare IT and medical devices experience (blog at http://healthcareguy.com) • 15+ years of technology management experience (government, non-profit, commercial) • 10+ years as architect, engineer, and implementation manager on various EMR and EHR initiatives (commercial and non-profit) Author of Chapter 13, “You’re the CIO of your Own Office” www.netspective.com 2
    • NETSPECTIVE What you’ll learn in this briefing Wireless capable medical devices with significant software and data integration are the future Topics Key takeaways • Things that kill and harm human beings today are very different than just 100 years ago • Health policy and payments are shifting to deal with new realities • Marketplace and industry challenges for device vendors • Why wireless connectivity is good business • Why wireless connectivity is a disruptive innovation • Wireless is a business enabler but there’s a lot to consider. • Hardware, sensors, and software are transient businesses but data lives forever. He who owns, integrates, and uses data wins in the end. • Data from devices is too important and specialized to be left to software vendors, managed service providers, and system integrators. www.netspective.com 3
    • NETSPECTIVE Life expectancy is increasing… …but the rate of growth is slowing www.netspective.com 4

    • NETSPECTIVE Key regulatory questions Will the FDA accept networked safetycritical systems? Are connected devices safe enough for medical devices? Yes Yes but you must prove it The best regulatory strategy is to abstract design specifications to minimize sustaining engineering: • Intended use • Predicate device(s) • Design approach and how OTS • components are used • Design input specifications • Risk and hazard analysis Abstract Specifications: • Remove dynamic characteristics • Manufacturer, model, version • Performance specifications • Clock speed • Memory • Storage • Industry standards • Third party certifications Source: Tim Gee, MedicalConnectivity.com www.netspective.com 34
