GOAL convenience for caregivers
  • A good system will
  • be preferred over a manual system
  • return more info then a manual system
  • simplify an otherwise tedious task
  • Integrate easily with other hospital systems
  • Allow moderate degrees of customization
  • Patient id format matching and checking
  • Inclusion of desired extra fields
  • Elimination of unwanted field requests

Wellspan Glucose System Components
  • House wiring / interconnect
  • A reliable cable plant is key to a successful
    installation
  • House wiring may be used for Ethernet, serial, or
    telephone connections
  • Basically its nothing more then a quality
    extension cord for your wiring needs
  • Learn your institutions wiring identification
    scheme. Itll may help you locate devices.
  • Report problems by connection id information
  • At Wellspan the first three digits indicate the
    central wiring closet where the cable terminates
    and the remaining digits are the sequence number
    or patch location for that cable.
  • Consider custom length cords. Bundling can be
    done but exact length cables stay out of the way

  • Router interfaces 1,2,3,4 join FOUR tcp/ip
    networks.
  • Without the router we can not segment traffic.
  • With the router we can have local traffic stay
    local impart network access controls
  • When a router is used each host must have
    knowledge that it needs to use the router for
    destinations not on its own subnet.

Component FunctionsGlucose meter
  • a limited function computer with i/o capabilities
    for
  • display and keyboard / bar code reader input
  • test strip subsystem and input
  • Optical communications port to transfer data base
    field type data.
  • Input
  • operator lists / badges
  • Database type field parameters
  • Output
  • Patient id
  • Patient test number
  • Time
  • Patient test result value

19
Docking Station
  • IR (infra-red) linking to meter
  • Physical and/or Optical connection to meter
  • May be passive or may provide expanded
    communications features absent in the meter to
    offer serial RS-232 communications to existing
    hospital owned standards based Networking devices
    like a hospital owned Ethernet terminal server.
  • The data stream from the meter/dock is like a
    single file row of marbles coming down a tube in
    sporadic pacing.
  • References to the docks data port may include the
    terms serial, asynchronous, com port, rs232 port,
    rs485 port.

20
Asynchronous Ethernet Terminal server
  • A conversion device or communications converter
    to allow the connection of slow speed low cost
    devices to high speed Ethernet networks. (marbles
    to envelopes)
  • Meter and dock speak asynchronously typically at
    only 9600 bits/second or about (9600/8) 1200
    characters per second.
  • Serial communication is typically referenced by
    bits or single characters
  • Ethernet by contrast speaks at 106 bits/second or
    about (106/8) 1,250,000 characters per second
    with typical modern networks NOW using fast
    Ethernet 107 and gigabit 108 bit rates.
  • Ethernet communication is typically referenced by
    packets of data

21
Ethernet terminal server (cont)
  • The job of the terminal server is to package
    the async data into a larger package for
    efficient transport on a high speed network. i.e.
    Japanese subway stuffers.
  • The data stream on the Ethernet side of the term
    server would be analogous to when a train comes
    by with open box cars and you fill each boxcar
    without the train stopping in a clocked loading
    fashion such that each boxcar represents a data
    packet from the terminal server. Many cars will
    leave only partially filled and sometime 2 or 3
    cars may be needed for one big packet that has to
    be split up because its too big or takes to long
    to get in the current passing boxcar!
  • One box car or packet may contain multiple
    individual threads between several meters on a
    common terminal server origination or source to a
    common destination such as the LIS host offering
    multiple threads to accommodate communications
    with each connected meter.

22
Cloverleaf (QDXI) interfacing and HL7
  • An interfacing program executing on the LIS
    receives the inbound testing information but at
    Wellspan the meter actually first sends to the
    Lifescan server (Lifescan Workstation) which then
    sends to an interface engine which then sends to
    Cerner (the LIS) via HL7 data exchange protocol.
    HL7 health layer seven
  • The advantage is that an enterprise hub and spoke
    interfacing plan can be adopted saving per host
    interface ports and resources.
  • Consider this example 6 host hospital
    enterprise
  • full mesh interfacing..interfacesn(n-1)/2
    or 6(5)/2 15
  • hub-and-spoke interfacing..interfacesn(1)
    or 6(1) 6
  • A hospital with only 20 hosts would take 180
    interfaces versus 20 interfaces

23
LIS Laboratory Information System
  • The LIS is the eventual receiver of the
    collected test data. The LIS (Cerner) receives
    the data via the HL7 data exchange protocol from
    Cloverleaf interface engine.
  • A communications application module purchased for
    the LIS must be running and listening for this
    inbound data stream.
  • The Cloverleaf and the LIS being Ethernet capable
    devices exchange packets (boxcars) filled with
    Lifescan transaction data that has been
    aggregated by the Lifescan Workstation.
  • TCP / IP protocols job is to direct and route
    those data packets to the appropriate software
    communications endpoint on the LIS host.
  • This endpoint is often called the listener, the
    interface socket, or host virtual port.

24
that old black magic. DATA NETWORKING
  • The part we just skipped is Networking's
    specialty and what puts bread on the table for
    Keith and Kevin !!!!!
  • What really happens when my glucose meter begins
    to upload data to the network.
  • How does the meter data actually make it to the
    LIS host?
  • What keeps the data from getting all jumbled
    together when 5 meters all upload concurrently?

25
MAC and IP addressing MAC addressing
  • Every Ethernet device EVER made has a globally
    unique MAC or media access control Ethernet
    address assignment. This assignment is burned
    into the chip set of each and EVERY Ethernet
    communications port of any device that can be
    Ethernet attached.
  • In our example the terminal server would have one
    and the LIS host would have one.
  • A MAC address is 48 bits long and is almost
    always written and represented in the computer
    world in hexadecimal.
  • 281,474,976,710,656 possibilities
  • example
  • 08-00-2b-01-af-19 hex
  • 0000 1000 0000 0000 0010 1011 0000 0001
    1010 1111 0001 1001 binary equiv
  • 8,796,814,552,857 decimal equiv

26
IP addressing
  • Every Ethernet device added to a tcp/ip network
    needs to get an assigned IP address. This
    assignment is typically awarded by your
    institutions network guru or IP address
    administrator.
  • In our example the terminal server would be
    assigned an ip address so it could talk to other
    tcp/ip systems on your network. An ip address is
    a 32 bit number typically expressed in decimal
    format. The left portion of the assignment
    reflects the network (think area code) that the
    host is enrolled in and the right portion of the
    assignment reflects the host number in that
    network. (think your 7 digit phone number)
  • An IP address is 32 bits long and is represented
    in the computer world in decimal using what is
    called dotted decimal notation.
  • Example 192.168.236.104
  • Above in binary is 1100 0000 1010 1000 1110
    1100 0110 1000
  • Full decimal value would be 3,232,296,040 but
    this reference is not used as the dotted decimal
    notation more easily shows network enrollment
  • 32 bits 4,294,967,296 possibitlies
  • Private REUSABLE addressing ranges
  • 192.168.0.0 thru 192.168.255.255 first dot
    boundary (/24 bit)
  • 172.16.0.0 thru 172.31.255.255 second dot
    boundary (/16 bit)
  • 10.0.0.0 thru 10.255.255.255 (/8 bit)

27
IP addressing/subnet masking
  • Example 192.168.236.104
  • Above in binary is 1100 0000 1010 1000
    1110 1100 0110 1000
  • Mask 255.255.255.0 1111 1111 1111 1111
    1111 1111 0000 0000
  • The above 32 bit mask allows 224 bits for
    network and 28 bits for host numbers
  • MASK Value
  • Typical masks are
  • 255.255.255.0 - allows last byte to be all host
    numbers 28 255 (actually 256-1)
  • 255.255.0.0 - allows last 2 bytes to be for host
    numbers 216 65,535
  • 255.0.0.0 - allows last 3 bytes to be for host
    numbers 224 16,777,215
  • BUT they can be on a NON-classful boundary
  • 255.255.255.240 - CUSTOM mask example
  • allows only the last HALF of last byte to be host
    numbers 24 15
  • Every host in a tcp/ip network needs an ip
    address, a mask, and a gateway
  • Mask indicates where the network / host boundary
    marker is.
  • The mask is the masking tape that tapes over the
    COMMON NETWORK PART of the address that is not
    important when talking within your network.

28
IP addressing/gateway
Host portion
Network portion
  • Example 192.168.236.104
  • Above in binary is 1100 0000 1010 1000
    1110 1100 0110 1000
  • Gateway 192.168.236.253
  • Above in binary is 1100 0000 1010 1000
    1110 1100 1111 1101
  • Mask 255.255.255.0 1111 1111 1111 1111 1111
    1111 0000 0000
  • The gateway address will always be a similar ip
    address to yours in your local network.
  • The gateway address you use will always be the ip
    address of a router interface.
  • Your GATEWAY to the rest of the IP world.
  • You talk to it. It talks to the next level on
    your behalf.
  • The address you enter on your host for the
    GATEWAY will always be an address on YOUR
    network. It is who you DEFAULT to for getting
    beyond your network.
  • long distance to another area code.
  • Hence the name default gateway
  • An ARP address resolution protocol table in your
    pc maps host ip addresses you talk to, to that
    devices MAC address. Devices really talk MAC to
    MAC!!!

Tip ECHO test the gateway. If its not alive
then that net will be unable to talk outside of
its own area code. from your desktop pc issue
the command ping 192.168.236.253
29
IP addressing / dhcp or permanent (static)
  • The ip address can also be awarded by machine
    from a pool of predefined available addresses.
    This technique is called DHCP or Dynamic Host
    Control Protocol. This works great for devices
    that join and leave networks and works well if no
    one needs to access your host. DHCP can be setup
    to award you a temporary ip address, your correct
    mask and your assigned gateway.
  • A pc workstation works fine with a temporary
    dhcp address but a pc SERVER would almost always
    need to receive a permanently assigned address so
    other computers would know what to connect to.
  • The addressing typically used by POC system
    component will likely always be static addressing
    because like a server the addressing is
    permanently awarded per device so that other
    systems can find the POC system components using
    the same address each time.
  • Good static address example is www.google.com
    which really is 64.233.167.99
  • Good dhcp example is your office pc which only
    makes OUTGOING connections so it doesnt really
    matter if you use a different address tomorrow.
    You could still for example get to google.com!

Socket Communications
  • Socket communications is how the I.T. world
    refers to endpoints.
  • Two systems that are ETHERNET capable will use
    socket to socket communications for each flow
  • Meter A on term server 1 to the Lifescan
    Workstation would use a socket pair.
  • Meter B on term server 2 to the Lifescan
    Workstation would use a socket pair.
  • At least one endpoint must use an exclusive ip
    address or socket number to differentiate between
    the two flows. (reference slide 15)
  • Connect to your LIS host and then to an Internet
    sites on your work pc and then click start and
    run and in the dos window that opens type netstat
    a on your pc. It will show you an nice example
    of socket to socket communications
  • example pc to google
  • Example pc to CERNER via telnet

Tip
32
Sockets that receive connections
  • are called Listeners because they are at the
    ready to receive an inbound connection.
  • Are often called services or service sockets
    because they are typically tied via software to
    an application function like
  • telnet, or ftp, or webserver
  • Custom receiver application like Glucose meter
    data collection.

33
Application to Socket communications
  • The application can however be coordinated with
    an initiating socket with the other endpoint
    being the listener. Printing is an example of
    such a reverse direction of socket communications
    because the printer is listening for a connection
    for its next print job.
  • A listener may allow only ONE connection at a
    time or it may allow multiple concurrent
    connections.
  • THE computer with the endpoint that INITIATES the
    communications is NOT the listener.
  • Web server example of multithreaded listener
  • If the terminal server is the listener end
    example of single thread listener.
  • A busy listener will tell the end trying to
    connect to it that it is already busy or it may
    even allow a degree of queuing whereby it accepts
    a second, third or fourth connection but it may
    put that flow in a hold or stacking pattern till
    it can process the current on deck request.

34
Application to Socket communications
Click RUN, then click START then enter command
(win98) or cmd (winxp) and in the dos window
enter netstat a at the prompt to view all the
current socket connections on a pc. Heres a
partial clip from our Lifescan server.

netstat a is a harmless command to view
connection status.It can be executed at any time
on any pc w/o impact.
35
Wireless adoption
  • Current capabilities
  • Wirelessly connect the terminal servers
  • Future
  • Direct real time or hot spot wireless linking
    for each meter
  • Would help eliminate those times when no one
    remembers to dock and upload the days work from a
    meter.
  • Wireless Meter tracking. Where did I lay meter
    icu01???
  • Wireless daily audit of transactions w/o docking.
  • Meter peds06 did not report for 24 hours so the
    server will look for it and potentially alarm
    /email a system manager if missing.
  • Automated updates. All meters will be software
    upgraded to now accept an additional bar code
    format for the new to be adopted patient id
    system.
  • Or all meters will be upgraded to Lifescan
    operating system version 6.12 from 5.83

36
What can POC users do to make for an optimal
Network deployment at their institution?
  • Establish clear installation locations that are
    not overcrowded with other nursing functions.
  • Name everything with a short, lower case,
    meaningful name during the design phase and stick
    with it.
  • Too many devices here!! A horrid wire mess from
    msicu
  • Wheres Waldo?
  • Find the istat meter dock!!!!..????
  • The lifescan doc is on the wall. Note its clean
    install helps keep it easiest to find but front
    clutter impacts its accessibility.

37
What might POC users be asking of POC vendors
  • for future product considerations give thought
    from a Networking perspective.
  • Does the vendors devices allow you to use
    existing network resources.
  • You may already own terminal servers? Why buy
    more? We shouldnt have.
  • Can they use DNS or dynamic DNS for naming
    simplification and connection destinations? A
    netstat will then show names instead of
    addresses!
  • Can the peripheral devices be easily monitored
    for health status (SNMP, telnet and web access)?
  • Does the system support test and training data
    collection while the production system is live?

38
Other BEST networking practices
  • Neat cable work eliminates problems
  • Label devices and document connections
  • Give EVERYTHING an enterprise unique name
  • Think like a hacker when planning the install.
  • Hospitals have been lax on security for too long.
  • If the area is already cluttered dont expect it
    to improve with the addition of another computing
    device. Something gotta go or new space must be
    allocated.
  • If the installation looks permanent it will be
    permanent. If it is just splayed out on a counter
    itll be buried in charts and you can be assured
    of failures. If it didnt require tools to
    install it then it wont require tools to
    dismantle it and someone will.
  • Consider a semi-annual or regular equipment
    inspection and be prepared to make repairs and
    corrections. Time the inspection with your annual
    review and tout how youve assured continued
    meter reliability. If it breaks youll get the
    blame so why not get the credit.

BEST PRACTICES DNS Domain Name System
  • Whats DNS have to do with POC networking???
  • Forms a name to IP address relationship that is
    enterprise wide
  • Enter every ethernet device in your DNS. You
    would submit to your DNS administrator the
    official hostname and its assigned ip address.
    They will add an A record to your enterprise
    DNS so the name can be resolved to an ip address
  • Promotes good naming conventions
  • Aids dramatically in troubleshooting
  • Is the terminal server in ICU plugged in? The
    users say they cant upload?
  • Lookup the ip address of the Lantronix in ICU and
    find it is 192.168.22.8
  • So you do a ping to 192.16.22.8
  • ---- OR -------
  • Is the terminal server in ICU plugged in? The
    users say they cant upload?
  • Ping the server by the enterprise naming
    convention for Lifescan terminal servers
  • So you do ping ts-ls-icu01 (names should use
    only alpha and numerics and the special character
    for best practice.add 01,02 at the end for
    when you expand.)
  • What would the name of the terminal server be in
    pediatrics
  • Any traces or netstat reports will now present
    the DNS name of the device in the output instead
    of the IP address. Much more people friendly!!!

PING example - success
  • Whats a ping display look like when it is
    successful?

43
PING example - failure
  • Whats a ping display look like when it fails?

Trace route example (tracert)
Whats a tracert display look like?
  • Note tracert (and ping) commands are case
    sensitive.
  • Two techniques shown
  • Standard trace with name lookup
  • tracert 192.168.236.104
  • Modified trace with resolve of names disabled
  • tracert d 192.168.236.104

    an IP address and address awards can be made from
    the router w/o a dhcp server.
  • Dynamic but always reserved for your MAC!
  • Return to a net 5 years later and get the SAME
    address!
  • Integrated encryption already included.

Wellspan Glucose System Components
  • HL7
  • Health Level Seven is a syntax standard
    specifically designed by. the healthcare industry
    to facilitate patient data exchange between
    computer applications .....
  • Derived from the X12 EDI standard used for HIPPA
    compliant data transfer
  • take a look at a typical HL7 ADT message. This
    message is sent when a new patient arrives at the
    hospital. The patient's demographics are entered
    into HIS (hospital information system) and then
    the information is communicated to all the other
    systems to avoid multiple entries of the
    patient's demographic information.

  • HL7 messages are ASCII messages and the standard
    requires that they be "human readable". The
    (pipe characters) are considered readable
