  • As far as tracking and visibility to the operations of any corporation the use of RFID has been looked at for sometime. As the first and early adapters Wal-Mart and DOD is enforcing it on their suppliers/vendors and eventually the whole retail industry will follow. If you look at the retail industry it is a broken up divided loop. The retailer will have several vendors, however each vendor might have only one Wal-Mart – only 10% of its business. Now in the healthcare the hospital is a closed loop environment, much easier to control. By looking at the healthcare industry now we have several entities looking at how to achieve efficiency through better utilization and control of their operation via better visibility and traceability. As indicated we have been talking to all sizes and shapes healthcare providers (i.e. GPO, Systems, big & small hospitals) also we have seen several niche solution providers coming up with all variety of technology solutions to solve the same problem. Many entities in the healthcare industry are implementing RFID pilot programs. Mainly, their approach is to evaluate only a group of valuable items of each component in the supply chain separately. The current projects don’t address the overall outcome due to their limited scope and concentration on only high-valued assets. We believe that tagging items with lower value level will help improve the actual individual caregiver’s efficiency, regulatory compliance, organizational confidence and patient safety.
  • Even tough each one of those projects may be based on a solid BC and a proved ROI, the real business benefits potentials of the usage of RFID related technologies is still unexploited in most of the cases…
  • All of the previously described efforts are unlinked and typically seek to serve a particular purpose without considering the other dimensions of the environment and the demands they impose Other operational factors include: - Financial pressures for profitability Compliance requirements for SOX & JCAHO Improve quality of patient care - Leverage existing infrastructure (from the IT perspective also)
  • Increase the Safety and Quality of Patient Care Enable clinicians to locate available assets. Enable equipment distribution to dispatch assets rapidly. Increase responsiveness to linking moveable assets to patients. Increase responsiveness to linking patients to non-movable assets. Reduce Asset Costs Increase asset utilization. Eliminate unnecessary assets. “ Right size” rental vs. owned assets. Reduce maintenance costs by decreasing unnecessary assets. Reduce shrinkage. Improve management of rented assets. Gains in Labor Productivity Search and find. Increase maintenance efficiencies. Eliminate manual processes.
  • There are many many other sources on each branch…
  • Be sure to explain why we may combine ACTIVE+PASSIVE+BARCODE If an asset moves from a WiFi zone to a NON WiFi zone, you should be able to keep tracking the asset through Passive RFID readers. Reasons why everything should be Bar-coded: Inventory In case the network goes down Physical scanning with simple devices Leverage existing barcode infrastructure and information To cover areas with no infrastructure at all (this means process enforcement)

    3. 3. RFID related technologies at work Specialized solutions are in place or being currently tested at several institutions to perform: Technology is already proven and supported by several success cases Counterfeit product tracking Patient medication control Inventory management Caregivers tracking (assistance) Patient tracking (elders/ infants) Point of use tracking
    4. 4. Context and Players Patient & Financial Health Caregivers Locating Assets Highly Movable Elusive Expensive Assets Patients Using Operational Excellence and patient care is derived from people, processes, management controls and technology A coordinated effort is critical to the health of the patient and financial health of the hospital. Clinical Staff Inventory Finance Maintenance Procurement Purchase Rental Forecast SLA Negotiations Corrective Preventive Maintenance Central Supply Inventory Delivery Monitor and Control Ensure Profitability Risk Management Deliver Organize Control Operations
    5. 5. Why now? There is severe financial and operative derived risks by not assuring compliance <ul><li>SOX presents a high risk on asset reconciliation deriving on write-offs and high cost on inventory checks. </li></ul><ul><li>Regulations have been issued by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). </li></ul><ul><li>In order to remain accredited as healthcare facility, organizations are required to demonstrate that life support equipment receives a high priority in their equipment maintenance programs. Enforced by July 1, 2005. </li></ul>Bringing more patients may increase revenue but not necessarily profits <ul><li>In an industry where patient service comes first, the lack of profitability in many healthcare providers has been reluctantly tolerated. Not Anymore. </li></ul><ul><li>Profitability is not achieved solely by more patient acquisitions but trough efficiency as the key for operational excellence. </li></ul>Lack of profitability and risk management drives adoption … efficiency efficiency efficiency Patients Capital Profit + _ Opportunity Threat SOX JHACO Deadline Risk
    6. 6. Typical problems in a hospital scenario Location Services applies to specific industry processes High concentration of assets not being utilized Leased asset that was ready for return but not visible Available asset, but not visible , often resulting in replacement by procurement Lost asset during a transfer Employee spending valuable time locating assets
    7. 7. Typical problems on core processes Location Services applies to specific industry processes Shortage of staff Out of flow during supervision rounds Maintenance due for a defibrillator Unauthorized exit on mental health Soiled area entrance & status change IV Pump on idle for too long Unauthorized asset removal IV Pump on idle for too long
    8. 8. Asset Utilization and Life Cycle Control Asset hoarded in a storage room Paying late rental fees Shrinkage by theft or during transfer Clinicians wasting time looking for available asset Unnecessary purchases Asset requires maintenance Unsatisfied patient Visualizing the day-to-day problems Knowing where the assets are to increase utilization, ROI, control and compliance. Asset’s ROI Usage (+) (+) (+) (-) Usage (-) Usage (-) Utilization Impacts Financial Results Purchase Receive Use Store Maintain Plan Dispose Refurbish Inventory Asset Control Life Cycle
    9. 9. The Roots of the Problem Solving the causes of poor Asset Utilization and Control positively impacts other core processes Our understanding of your operations enables us to identify the causes at its source. Asset Utilization & Control Proper Compliance Tight Financial Control Efficient Operations Accurate Planning & Forecast High Quality Clinical Services Timely Maintenance Asset Visibility Asset Status Asset location Unknown last location Asset availability Unknown actual status etc… etc… Asset Accountability Process Enforcement No event recording Paper based & no time No responsibility No event recording etc… etc…
    10. 10. Suggested approach Integration of open standard technologies to cover all available methods without relying solely on process enforcement Let your current operation and infrastructure maximize the return of your assets. Accurate location and tracking by triangulation Presence location by zone Mobile scan to report last known location and status Browser based update of information Exit and entrance control Outdoor control Notifications via VOIP Phone (WiFi)  Leveraging existing WiFi infrastructure  Wireless data access  Automatic status changes, no human intervention  Messaging through the same Voice Over IP network Tagging is determined by the cost, elusiveness and portability of your assets Active RFID for highly movable expensive or elusive assets. I.e. Defibrillators, SCD (sequential compression device), Feeding pumps, IV pumps, Suction machines… Barcode support for low cost and/or fixed assets Passive RFID tags for mid-cost portable assets I.e. Oxygen cylinders, Stretchers, Hypothermia pads, C-PAP I.e. Waiting room TV’s, Computers Printers, Furnishing – tables, side chairs, Slide tables
    11. 11. Asset Visibility and Status Control is the Key Controlling assets lifecycle to increase utilization, control, compliance, etc. Asset Lifecycle Downtimes in Utilization Allocate The Acid Test for ROI on Utilization Discharge Soil Locate Idle Unavailable Maintenance Release Available Visibility Status SLAs SLAs Demand Setting Theoretical Capacity <ul><li>More capital expenses (new purchases) </li></ul><ul><li>More demand from the nurses and operations staff </li></ul><ul><li>More rental expenses </li></ul><ul><li>More maintenance down time </li></ul><ul><li>More capital expenses (consumable purchases ) </li></ul>Select & Tag Record Retool Evaluate Based on cost and demand Business as usual Introduce visibility and control Evaluate results on operations In Use Idle Unknown Idle Available Unavailable By Encounters   Number of Physicians 400 Productivity Measure Physicians 4,200 Number of Mid-level Providers 200 Productivity Measure Mid-level Providers 2,100 Total Theoretical Capacity of Encounters 1,722,000 Real Number of Encounters 1,200,000 Capacity Rate 70% By Occupancy   Set Up & Staffed Beds 400 Days the hospital was opened 365 Theoretical Capacity of Occupancy 146,000 Real Inpatient Days 123,458 Occupancy Rate 85% Maximum Expected Utilization Rate for Assets 77% Number of Discharges 150,000
    12. 12.

    15. 16. Location Modes Triangulation Virtual Zones Presence Location Item Z is located some where on area E Item X in located on area A on X-Y position A, B and C virtual zones within a physical area Triangulation is provided with 2-10 meters accuracy depending on the environment and the technique used to determine positioning such as TDOA or RSSI. Presence location is reported when only one access point can detect signal from one tag. This method is useful for large items on very well defined zones. When several access points share the same area is possible to define virtual zones within a map, using walls as reference or simply virtual spaces.
    16. 17. Location Modes Physical Entrance & Exit Telemetry Exteriors Support Container G45H is the present at X-Y on north yard Wheelchair 48 crosses exit B9 at 7:04:30 PM Temperature on Food container FF45T is 34°c An Exciter triggers Tags to transmit at specific points, adding the Exciter ID to the standard Tag message. Provides instant knowledge that a Tag passed through a gate or doorway or some other tightly defined area. The Exterior location receivers are designed to operate outdoors. Supports extreme weather operation conditions and provide wide range coverage. A serial port is available on each tag to support Telemetry data reports. Can store up to 10 messages of 10 bytes each. A call button can also be provided.
    17. 18. RFID Evolution - Supplementary Technologies Bar Code – Designed to provide check points during processes manually Active RFID – Designed to provide real time location and data collection automatically Passive RFID - Designed to provide check points during processes automatically Load Manifest Cross Docking Delivery Manufacturing Load Manifest Cross Docking Delivery Manufacturing Load Manifest Cross Docking Delivery Manufacturing Bar Code is been used for decades and is widely adopted. The cost of tags and infrastructure is very low. Is labor intensive and the reliability of the date depends on processes and human performance. Passive RFID has reach maturity and is been adopted primarily on retail and CPG. The cost of tags is prohibited for item level and the infrastructure is expensive. Accuracy is still an issue but provide greater visibility and labor savings Active RFID will abandon RF and adopt WiFi. The cost of tags will continue to be high, but the adoption of standard WiFi infrastructure will lower the investments. Provides greater visibility and data collection and process control.

    21. 23. Positioning Events vs. Logical and Business Events Business Events Physical Events Logical Events The logical event will be received by an human who would take decisions or by an application that will be able to apply a business rule and or execute a transaction. An event processor server will receive the location message and process the physical event to monitor specific conditions that could originate an logical event and communicate the information to the application tier. A Location Engine will determine the exact location of a Tag and provide X,Y,Z positioning along with the map of reference and a unique ID represented by the MAC address of the Tag. Visibility = ID + (X,Y,Z) + Map The application will process the event and ask a clerk to very the status and take the asset to the soil room The Dwell-Absence event monitor will detect the event as a potential asset release and send a notification. An IV Pump will report its location in the same position for over 36 hrs.

    29. 31. Monitors Detects and reacts to presence of a tracked entity or category of entities on a specified location. Detects entrance to/from a location as well as the passage trough checkpoints with the capability of determining the direction of the movement Zone Entrance / Exit Shortage / Overflow Detects when a specified location contains more/less entities of the specified category during a predefined period of time. It is also triggered when too many entities (of the specified category) have passed through a specific point during a predefined time interval Allows the tagged entities to transmit telemetry data to the central server trough a serial port in the tags. The system is then capable of parsing the message and perform regular expression comparisons. The tags can also provide a call button feature to transmit predefined messages to the server to signal specific events. Telemetry / Call button Out of Flow Monitors an entity’s location and progress over a specified route. It is capable of detecting missing route points and delays over transit periods. Detects when an tracked entity or category of entities stays inside or outside the specified location longer than the indicated period of time. The absence monitor is also able to detect when a tracked entity is no longer visible by the system due to a tag failure or tag tampering. Dwell / Absence Friend / Foe Detect when a pair/set of entities get separated apart from each other more than a permitted distance or have been separated to different zones. Detects when entities of specified categories get close to each other more than allowed distance or remain on the same location longer that the specified threshold time. 1 2 3 4
