DM Register: Iowa ACO examined

Today's Des Moines Register has an interesting article on Iowa's first accountable care organization (ACO) at Ft. Dodge's Trinity Regional Medical Center.  Trinity is part of Iowa Health System.  You can find the article HERE.

The article presents an example of care provided to one cardiac patient, them explains the ACO concept.  It goes on to present arguments from both supporters and critics of the ACO concept.

Side Note: On June 1, 2012 the Des Moines Register is changing it's subscription model.  Therefore, I'm not sure if this link will be valid after that date.

Telemedicine Technology Planning Questions


Most bad technology solutions are not created by bad decisions, but by bad questions.  In this post we’ll look at questions which should be part of a telemedicine technology decision making process.  For additional background on telemedicine, please refer to my previous telemedicine posts including a telemedicine overview, terminology, and technology options.  As I've said in my earlier posts, I'm not an expert in telemedicine.  I'm just passing along what I've learned as I explore this very interesting topic.

I’m going to lay out questions and considerations which you can use to facilitate your planning process.  I hope that as you read this you’ll think of many more questions nested within each area.  And that’s really the purpose of this post, to get you thinking of the right questions. 

Before making any technology decisions, it’s important to have a defined telemedicine business case and strategic need.  Technology is the means to an end, not the end itself.  If technology is selected without a defined business case and strategic need, it increases the odds of making improper and costly technology decisions. 

Not to put too fine a point on it, but technology decisions are wrapped up in general operations decisions, which are ultimately constrained by a budget.  The budget, of course, is constrained by reimbursement, whether fee-for-service or some flavor of capitation.  So figure out how much you can receive before you commit to how much you have to spend.

Information needs
What information will be received? 
What information will be sent out?
What is the quality of the information to be received and sent? 
What is the quantity of information to be received and sent?
When is the information to be received and sent?
What is the format of the information to be received and sent?

This may seem obvious, but it’s important to define information needs.  If a provider needs patient history prior to the telemedicine encounter, there needs to be someone and some process to make that happen.  If there is need for vital sign or mental state screening during the encounter, there needs to be someone and some technology to make that happen.  Maybe it’s an inexpensive fax machine, maybe it’s and EMR, maybe it’s a full-scale integrated telemedicine cart.  Whatever it is, unless information needs are clearly defined, it’s not possible to make an informed technology assessment.

Wrapped into this discussion is sharing of patient information.  This includes considerations for EMR and HIE.  If there’s a need to send out referral letters and CCD/CCR, the system will either need to handle it or there needs to be a manual process.  Volume counts here, a couple patients per day are much different than managing the process for 15 patients per day.

At some point there must be charge capture, so that will need to be considered. How does the clinical information flow to the billing clerk or CBO?

The Who
Who is the patient population? 
Who is facilitating the encounter for the patient (patient helper)? 
Who is the provider?

It’s my hope that planners will consider patient population needs.  The environment, tools, and process should create a positive patient experience.  A repainted closet entered from a busy waiting room may not be optimal for mental health patients.  A cool room with only technology devices may not be the best setting for an elderly population.

Patient population also impacts the telemedicine setting.  Ambulatory mental health patients can go to a fixed telemedicine location.  Elder care facilities may require a cart solution.  If the telehealth equipment is to be moved between facilities, then an even more mobile solution is called for.

Regarding the patient helper, if they need to attach an ECG, take vitals, or ask screening questions, they’ll need the proper clinical credentials and training.  They’ll also need aptitude and training to operate, troubleshoot, and maintain telemedicine equipment.  Finally, working with a remote provider is different than working with one shoulder to shoulder, so the patient helper will need the appropriate skills and training to be effective.

Regarding the provider, this person will need to facilitate the technology to successfully conduct a telemedicine encounter. This includes technical skill, but also skill and training on conducting a successful remote encounter.

Where
Where is the patient location?
Where is the provider location?
Does the location have adequate Internet connectivity?
Is the equipment secure?
Does the patient encounter location provide privacy and security for patient and data?

If you’re thinking of telemedicine, you’re probably already considered the care facility or setting.  But within that facility the equipment will need to be stored and secured.  The patient encounter location will need adequate privacy and security.  There will need to be a process for handling the patient and PHI before and after the encounter.  Any patient information will need to be secured and protected, which includes all pieces and parts of the telemedicine technology solution.   After all, you don’t want unauthorized people surfing the internet or playing with a camera and come across some bit of patient PHI.

It’s also important to consider where the provider will be located.  Most of the time they may be in their practice office, but will they also be available when making rounds or when otherwise out of the office?  If so, you’ll need to address a laptop or mobile solution for the provider. 

How
How is the telemedicine encounter and related information intended to be used?

This may seem basic, but will patient visits be diagnostic, follow-up, or chronic disease maintenance?  Knowing this may steer your technology decisions.  Assessing a patient’s lightheadedness differs from discussing their hypertension plan compliance.

When
When will encounters be conducted?
Will appointments be scheduled, walk-in, or on-call?
Are the patient care site, the patient helper, and the provider available for the appropriate days and time?

Typically we think of “when” in terms of scheduling method: scheduled, walk-in or on-call.  However, telemedicine presents its own set of coordination challenges.  This may not seem like a technology issue but it is.  If the remote patient location needs to be scheduled, there needs to be a way to track that.  Same goes for the patient helper and provider.  Is there shared scheduling software?  If it’s a paper schedule (a no-tech solution), who manages the schedule and coordinates the people and locations?

Conclusion
I hope these questions have provided some insight into what it takes to plan a telemedicine technology solution.  As I said at the beginning, this was intended to prompt to you think of additional questions if you’re exploring telemedicine and telemedicine technology.  If you’d like to discuss telemedicine and technology further, please feel free to reach out to me through this blog or via email.

Straight ahead,

Seth Godin: Digital analogs are no longer sufficient

I'm happily writing my next post, Telemedicine Technology Decisions, when Seth Godin once again writes something that forces me to stop and think.  Darn you Seth Godin!  You can find his blog HERE.

Look for my Telemedicine Technology Decisions post tomorrow.

Part 3: Telemedicine Technology


“Rampart Hospital, this is Squad 51.  Dixie, you read me?  Out.”  The sultry cool nurse Dixie McCall, complete with white nursing uniform and hat, calmly coos, “Rampart, copy.  What’s your situation 51?”   And with that, many Americans were introduced to telemedicine by the TV show Emergency.  It seems that in every episode, paramedics Gage and Desoto arrive on scene to treat a patient with chest pain, open up their toolbox, screw in a silver antenna, and start communicating with Rampart Hospital.    The paramedics talk with the unflappable Dr. Kelly Brackett, and eventually send an ECG over their radio unit to Rampart Hospital where it’s read by Dr. Brackett.  “Squad 51, this is Brackett.  Give the patient 2 units Ringers Lactate, stabilize and get him here STAT.  Out.”    Pretty cool stuff back in 1972. 

In this post I’ll explore some of the telemedicine technology available today.  Remember my focus is on solo and small group practices, so I’m not going to discuss enterprise level technology in detail.  Or emergency medicine (sorry Emergency fans).

For unfamiliar technical terms, try referring to my prior post, Telemedicine: Terminology LINK.

I’m going to break this down into the following components: telecommunications (audio/video); diagnostic devices and information; patient record; and aggregation tools (which bring together or combine capabilities of the other components).

The “tele” part
So how does the audio and video move between the doctor and the patient?  Well, it most likely is not over POTS service.  POTS stands for Plain Old Telephone Service, and it is the type of telephone service in most homes and many small businesses.  It’s the basic analog service that has been around almost unchanged since the late 19th century.  In allows for two-way voice communication, and with a modem allows a user low-bandwidth access to the Internet.   It’s good for voice, but too slow for video and data.

Most likely the “tele” will be provided by a digital service.  This is due to the larger bandwidth requirements for video.  So what are our digital options? 

From a network perspective, there are three possible topologies when deploying a teleconference system: 1) Private internal network; 2) Teleconference service network provider; and 3). Public Internet.

Private internal network
A private internal network requires that the doctor and patient sites all be on one network.  This is called a wide area network (WAN) and is more typical of a hospital system with outside clinics and multiple locations.   This is not normally the case for a solo or small group practice.  For a private internal network the owner must make sure there is enough bandwidth to support video teleconferencing and configure the network to optimize the teleconference network traffic.  They will typically purchase dedicated video teleconferencing equipment such as Polycom RealPresence or Cisco TelePresence.  These systems enable group video teleconferences as well as one-to-one.

Teleconference service network provider
In this scenario the teleconference network, hardware and software needs are handled by a vendor.  Teleconferencing will typically run as a service they overlay onto the Internet using their servers, and they may sell or lease and support the teleconferencing equipment.   Think of it as a turnkey solution.  This may be used in a situation where a practice doesn’t have a WAN or the technical resources to support teleconferencing, but needs to have robust teleconferencing capabilities.    

The same type of dedicated video teleconference equipment could be used here as we discussed above.  However, if one-on-one patient encounters are the primary purpose for teleconferencing, then less expensive desktop devices can be used.  Desktop devices incorporate a codec unit with audio and video capabilities.  It can take the form of a telephone with video screen, or a high quality monitor with built in camera, codec and networking hardware.  Or, instead of a separate piece of hardware it could even be a software application installed on a computer with microphone and video camera capabilities. 

Whichever desktop device is ultimately chosen, the technology behind the scenes is the same.  In fact, it could be that the patient station has a standalone desktop device, and the provider station has a computer application.   You just need to determine which device best suites your needs, which is a topic we’ll address in the next post.

Public Internet
Our third option is the public Internet.  The teleconference will run on the doctor’s internal network, travel over the public Internet, and be connected to the internal network at the patient location. This is a likely scenario for small business and medical practices. 

The advantage of using the public Internet is that it’s less expensive and requires less technical knowledge.  The disadvantage is there is less control over the performance of the network.  And that’s important because video requires an orderly and consistent network.  Video, just like everything else on the Internet, is broken into little pieces called “packets”.  These packets travel willy-nilly across the Internet, sometimes traveling different paths.  But because they have delivery address information imbedded in them, they get to their destination.  Once there, the packets are reassembled into video.  For video, the order the packets arrive in is important because the 30th second of video must run before the 31st second and not before the 29th second.  If the 30th second is delayed, you see a jerky image.  On a private internal network and vendor supported network, the network administrator can give the video packets priority so they always move in the fast lane.  But the public Internet is the Wild West.  More often than not this works fine, but sometimes it doesn’t. 

So what are our options when using the public Internet?

Well, first let’s look at a common Internet program, Skype.  Skype is an online service which provides audio and video communication between subscribed users.  Computers at both ends need Internet access, the Skype software, video camera, microphone and speakers. 

Skype has limited video capabilities (low definition) which are dependent on the bandwidth available at both ends of the call.  And while the call is encrypted, there are still questions as to whether Skype is HIPAA compliant.  So Skype could be an option for a specialty such as mental health which may not require “medical quality” video.  “Medical quality” video refers to video of a high enough quality to enable the viewer to perform assessment and diagnosis. 

While mental health has been using of Skype for a few years, a specialty such as dermatology, with its need for medical quality video, would not be appropriate for Skype. 

Skype is just one of a whole marketplace of teleconference applications.  Another one is Cisco WebEx. 

For higher quality audio and video, we look to desktop teleconferencing devices.   A desktop teleconferencing device consists of a user station with audio and video capability at both the doctor and patient sites, and the audio/video signal is compressed and decompressed as it passes from one station to the other.  This type of equipment is typically used with a high speed Internet connection such as DSL or T1.  Another option, ISDN, is available, but is typically cost prohibitive for smaller applications.

The teleconference session is just like a standard phone call.  At one station the user calls the other station, either using a phone number, an IP number (a device’s unique Internet address), MAC (a device’s unique hardware address), a user name, or some other unique identifier.  The person on the receiving end is notified and answers the call, thereby initiating the session.  Typically the teleconferencing equipment is preset with a directory so users know how to initiate a session.

Polycom and Cisco are two of the leading manufacturers of video teleconferencing products. Typically a customer will with work with a local teleconferencing vendor who will sell and install the equipment.

It’s important to remember that the teleconference will run over the doctor’s network and the doctor’s Internet connection, as well as the network and Internet connection at the patient’s end.  Be sure to follow manufacturer recommendations on bandwidth requirements, this is not the place to skimp.  Both sides of the call need sufficient bandwidth. 

With the booming popularity of mobile devices, their improving audio/video capabilities, and faster mobile and wireless networks, Polycom, Cisco and other venders are rolling out robust mobile device apps which integrate into the video teleconferencing ecosystem.

Confused yet?  Don’t worry, we’ll look at how to make technology decisions in the next post.

Diagnostic devices and information
If you can think of a diagnostic tool, someone has probably configured it to connect to a computer.  And if it can connect to a computer, it can be used for telemedicine.

Here is a list of diagnostic tools I recently found at AMD GlobalTelemedicine’s website: colposcope, dermascope, Otoscope, Ophthalmoscope, General exam camera, ECG, Spirometer, Vital sign spot monitor, Medication dispenser, Non-mydriatic retinal camera, high definition (HD) camera and illumination, standard definition (SD) camera and illumination, x-ray, x-ray scanner, ultrasound system, ultrasound probes, endocavity probe, stethoscope, dental camera, nasopharyngoscope, vital sign continuous monitor, vital sign spot monitor, microscope w/ video and/or camera output, and weight scale.

Connecting a diagnostic tool to a computer or computing device is accomplished with a physical connection (USB, serial port), network connection (Ethernet port and cable) or wirelessly (BlueTooth, wireless network).  For more detail on this, refer back to my posts on connecting medical devices LINK

So how do we get the diagnostic information from the patient site to the provider?  That answer will depend on how you handle patient information in general.  Ideally that information will be aggregated into a patient electronic medical record (EMR) which is available to the provider.  Another option is to use an aggregation device or software application which pulls all the patient data together and makes it accessible to the provider.  The next two sections address these area in more detail.

Lacking an EMR or means of aggregation, we can fall back on the good old fax for low resolution diagnostics.  HIPAA compliant email is an option, but not a good option.  The need for security and passwords makes this cumbersome.  Another option could be a secure file storage site on the Internet where files can be placed and later accessed by a provider.  Again, this must be HIPAA compliant, and is still cumbersome, especially if storing large files such as radiology images. 

Patient Record
At some point the telemedicine provider will want to review the patient’s history.  Optimally, both the provider and patient sites will have access to the same EMR software, or the doctor will have access to a portal containing the patient’s medical record.  Lacking that, the patient helper will need to transmit the patient record to the doctor via fax or HIPAA-compliant email. 

A benefit of an EMR is that it can incorporate diagnostic information gathered at the patient site.  To access a provider-supplied EMR, the patient site would need access to the EMR.  That would require either an EMR hosted outside the provider’s network, or configuring the provider’s network and EMR to allow outside access.  Appropriate licensing and user training would also need to be addressed.,

Aggregation tools - Bringing it all together
Aggregation tools are hardware and software tools which bring together the audio/video conference, diagnostic information, and the patient record. 

Aggregation software is the software which unifies the on-screen presentation of the video conference, patient record, and diagnostic information.  For example, at the patient end an ECG is connected to the computer and the reading is captured in the ECG software.  The patient helper enters chief complaint and HPI into the EMR.  At the doctor’s location, the user has a menu which allows her to select what information to view: live video, EMR, ECG software, or tile some combination of these on the screen.  The specific functionality varies between software packages, but you get the idea.

Aggregation appliances are equipment which physically incorporates communications, diagnostic, and medical record access into one package.  Typically these are carts which can be wheeled around as needed and include batteries and wireless communications. 

So what now?
Now that we’ve surveyed the telemedicine technology landscape, we need to figure out how to select the appropriate technology.  In my next post I’ll look at some scenarios and discuss how I would approach the technology selection process.

As always, if you have corrections, clarifications or additions, please feel free to let me know.  As I said in the first post of this series, I’m not a telemedicine expert.  I’m just passing along what I’m learning.
