Military Health – From Volume to Value

The digital world is driving us to act as both patients and consumers of healthcare information. For example – wearable devices, such as Fitbits, provide users with personalized data and the insight required to make more informed lifestyle decisions.

IoT_HealthcareAt the same time, healthcare providers are shifting to value-based care – from “pay per pill” to “pay for performance” and “pay for outcomes” while working to meet meaningful use goals. Comprehensive patient and population health data, and data collection opportunities enabled by the Internet of Things (IoT) can provide opportunities for healthcare providers – including military – to attain new insights and deliver the best care possible.

In a recent article in Health IT Analytics, EMC’s Roberta Katz writes, “In the current accountable care environment, where electronic health record documentation is being prioritized, this new realm of patient generated data can build on a caregiver’s clinical expertise and augment hospital protocols…With the use of IoT tools and sensors, we can review our own data in real-time, from the number of steps we are taking, cardio output, sleep cycles, blood pressure, and even mood, to become an ‘empowered’ patient.”

Modern tablet showing medical diagnosisWorking toward a transformative goal to achieve, among others, the results stated by Katz show that the Military Health System (MHS) http://www.health.mil/ is undergoing a disruptive application migration from the current system (AHLTA) to the new Cerner-based  MHS GENESIS – targeted for launch at the end of this year. Their goal: the ability to share health records electronically and document the complete continuum of care between MHS locations, private providers, and possibly Veteran Affairs.

Centralized data collection and analysis as part of an extended Electronic Health Record (EHR) system can provide a picture otherwise impossible to obtain – bringing together disparate information that alone does not raise an alert, but pulled together, can signal a need for intervention.

EMC is proud to participate in the Defense Health Information Technology Symposium (DHITS) 2016 on August 2-4 – and will focus on supporting the MHS Transformation. Please visit us at booth 401 to learn more about how Big Data analytics and data lakes are transforming military health.

Real “health care” happens when telemedicine is closely joined to a connected-care delivery model that has prevention and continuity-of-care at its core. This model has been defined well, but only sparsely adopted. As John Hockenberry, host of the morning show “The Takeaway” on National Public Radio, eloquently puts it: “health is not episodic.” We need a continuous care system.

Telemedicine makes it possible for you to see a specialist like me without driving hundreds of miles

How do we get the “right care to the right patient at the right time”? Schleidgen et al define Precision Medicine also known as Personalized Medicine (1) as seeking “to improve stratification and timing of health care by utilizing biological information and biomarkers on the level of molecular disease pathways, genetics, proteomics as well as metabolomics.” Precision Medicine (2) is an orthogonal, multimodal view of the patient from her/his cells to pathways to organs to health and disease. There are several devices and transducers that would catalyze telemedicine: Radiology, Pathology, and Wearables. I will focus on Radiology for this part of my three-part series, since all of these modalities use multi-spectral imaging.

Where first?
The world is still mostly rural. According to World Bank statistics, 19% of the USA is rural, but the worldwide average is about 30% which is a spectrum from 0% rural (Hong Kong) to 74% rural (Afghanistan). With the recent consolidations (since 2010 in the US) of hospitals into larger organizations (3), it is this 30% to 70% of the world with sparse network connectivity that needs telemedicine sooner than the well-off “worried well” folks who live in dense urban areas with close access to healthcare. China has the world’s largest number of hospitals at around 60,000 followed by India at around 15,000. The US tally is approximately 5,700 hospitals. The counter-argument to the rural needs in the US is the risk of reduction of physician numbers (4), the growing numbers of the urban poor and the elderly. Then there is the plight of poor health amongst the world’s millions of refugees who are usually stuck in no-mans-lands, fleeing conflicts that never seem to wane. All these use-cases are valid, but need prioritization.

Connected Health and the “Saver App”
Many a fortune has been made by devising and selling “killer apps” on mobile platforms. In healthcare what we need is a “saver app.” Using the pyscho-social keys to the success of these “sticky” technologies, Dr. Joseph C. Kvedar succinctly builds the case for connected health in his recent book “The Internet of Healthy Things” with three strategies and three tactics:

Strategies: (1) Make It about Life; (2) Make It Personal; and (3) Reinforce Social Connections.

Tactics: (1) Employ Messaging; (2) Use Unpredictable Rewards; and (3) Use the Sentinel Effect.

Dr. Kvedar calls this “digital therapies.”

The Vendor Neutral Archive (VNA) and Virtual Radiology
The Western Roentgen Society, a predecessor of the Radiological Society of North America (RSNA), was founded in 1915 in St. Louis, Missouri (soon after the invention of the X-Ray tube in Bavaria in 1895). An interactive timeline of Radiology events can be seen here. Innovations in Radiology have always accelerated the innovations in healthcare.

The Radiology value chain is in its images and clinical reporting, as summarized in the diagram below (5):

Radiology value chain

To scale this value-chain for telemedicine, we need much larger adoption of VNA, which is an “Enterprise Class” data management system. A VNA consolidates multiple Imaging Departments into:

  • a master directory,
  • associated storage and
  • lifecycle management of data

The difference between PACS (Picture Archiving and Communications System) (6) and VNA is the Image Display and the Image Manager layers respectively.

The Image Display layer is a PACS Vendor or a Cloud based “image program”. All Admit, Discharge and Transfer (ADT) information must reside with the image. This means DICOM standards and HL7 X.12N interoperability (using service protocols like FHIR) are critical. The Image Manager for VNA is the “storage layer of images”, either local or cloud based. For telemedicine to be successful, VNA must “scale-out” exponentially and in a distributed manner within a privacy and security context.

VNA’s largest players (alphabetically) are: Agfa, CareStream, FujiFilm (TeraMedica), IBM (Merge), Perceptive Software (Acuo), Philips and Siemens. The merger of NightHawk Radiology with vRad which was then acquired by MedNax and IBM’s acquisition of Merge Healthcare (in Aug 2015) are important landmarks in this trend.

One of the most interesting journal articles in 2015 was on “Imaging Genomics” (or Radiomics) of glioblastoma, a brain cancer. By bidirectionally linking imaging features to the underlying molecular features, the authors (7) have created a new field of non-invasive genomic biomarkers.

Imagine this “virtual connected hive” of patients on one side and physicians, radiologists and pathologists on the other, constantly monitoring and improving the care of a population in health and disease at the individual and personal level. Telemedicine needs to be the anchor architecture for Precision Medicine. Without Telemedicine (and VNA), there is no Precision Medicine.

Postscript: Telepresence in mythology
Let me end this tale of distance and care with a little echo from my namesake, Sanjaya, who is mentioned in the first chapter of the first verse of the Bhagvad Gita (literally translated as the “Song of the Lord”) – an existential dialog between the warrior Arjuna and his charioteer, Krishna. The Gita, as it is commonly known, is set within the longest Big Data poem with over 100,000 verses (and 1.8 million words), the Mahabharata, estimated to be first written around 400 BCE.

Dhritarashtra, the blind king, starts this great book-within-book by enquiring: “O Sanjaya, what did my sons and the sons of Pandu decide about battle after assembling at the holy land of righteousness Kurukshetra?”

Sanjaya starts the Gita by peering into the great yonder. He is bestowed with the divine gift of seeing events afar (divya-drishti); he is the king’s tele-vision – and Dhritarashtra’s advisor and charioteer (just like Krishna in the Gita). The other great religions and mythologies also mention telepresence in their seminal books.

My tagline for the “trickle down” in technology innovation flow is “from Defense to Life Sciences to Pornography to Finance to Commerce to Healthcare.” One interpretation of the Mahabharata is that it did not have any gods – all miracles were added later. Perhaps we have now reached the pivot point for telepresence which has happened in war to “trickle down” into population scale healthcare without divine intervention or miracles!

Digital Breast Tomosynthesis (DBT) is gaining traction as an ideal breast cancer screening tool.  Traditional mammography is a 2D image of the breast, and has been used as a standard screening tool for decades.  DBT improves on the 2D version by taking multiple images from different angles and creating a 3D representation of the breast.  The 3D representation allows physicians to view tissue from any angle and depth making it easier to identify lesions, giving the patient a more reliable diagnosis. Lesions can also be detected earlier, giving the patient an earlier start on treatment.  Recently, DBT received the support of the American College of Radiology and the FDA due to research showing its benefits over traditional mammography.

While this is great for patient care, IT staffs are going to be challenged with the explosive data growth.  Traditional mammograms are typically 30MB while a DBT is 350MB, representing over an eleven-fold increase.  In the US, there are about 39 million mammography procedures each year.  If just half of them were done using BDT, it would represent over 6,500 terabytes of data each year.  Overall healthcare data is growing at 48% a year (typically doubling their storage needs every two years); new technologies such as DBT are contributing to the growth.

EMC® Isilon® helps healthcare IT staffs cope with the growth due to its node based scale-out architecture and the simplicity of a single file system.  An IT staff can easily and quickly scale its storage infrastructure: simply plug in four cables, two power cords, and in about 60 seconds the resources of the new node are available.  There is no downtime or need to remap any application’s access to the storage. Seamless growth without downtime means no impact on patient care. That’s one of the reasons why seven out of the top ten US Best Hospitals for Gynecology use EMC Isilon.

Space Fury in a Med Rush for Information

7,000 to 8,000 patients a day. 1.89 million patients a year. All in a single 1,400-bed facility providing medical research, teaching and rehabilitation services. This is the Nanjing Children’s Hospital (NCH), the largest children’s medical facility in Jiangsu Province, China.

Doing the Right Thing Presents ChallengesHealthcare

If you caught Mad Max: Fury Road sometime in 2015, you could probably imagine what the situation would be like when desperate masses can’t get their immediate needs met. In the case of Mad Max, it was thousands of thirsty people deprived of water, a precious commodity held back by the evil cult leader, Immortan Joe, to control and keep them in constant disarray.

When someone enters with a medical emergency, the hospital has to find a way to treat the patient, even if the hospital can’t cope with the capacity. And for reason and one reason alone: because it’s the right, human thing to do. The good news is where human limitations await, technology opens doors.

Many hospitals like NCH rely heavily on a picture archiving and communication system (PACS) for x-rays, computerized tomography (CT) scans, and magnetic resonance imaging (MRI) scans. This system supports accurate and rapid diagnosis as well as treatment by radiologists and attending physicians.

One of the problems faced by NCH was how its existing storage, which supported both its PACS and Hospital Information System (HIS), could not keep up with the performance and capacity required to meet the demands associated with more advanced medical imaging technology.

A research paper titled Empowering Personalized Medicine with Big Data and Semantic Web Technology: Promises, Challenges, and Use Cases predicts by 2020, healthcare data will reach 25,000 petabytes, a 50-hold increase from 2012. As new medical devices are introduced to offer better treatment modalities to patients in hospitals, the demands of storing and accessing data will become more prevalent.

Making It Easier to Do the Right Thing

So what’s the solution? The flexibility of a single file system storage that makes it easy for physicians to search, archive and scale, when required.

In NCH’s context, EMC Isilon’s X200 Series scale-out storage was implemented as the platform for its PACS solution. It has not only enabled quick scalability, but maintains system performance as more users and files are added, speeding access to large numbers of recent and historical medical images and records.

Like how speed was critical to saving the lives of Max Rockatansky and Imperator Furiosa in Mad Max as they attempted to escape an entourage of villains, speedy access to information can also save the lives of patients. Every split second counts in medical treatment, sometimes making the difference between life and death.

“In the past, I didn’t want to add too many users to PACS because I knew it would affect the experience of the current users in the system,” says Sunnan Qian, IT Manager at NCH. “Now I can increase the number of PACS users as demand requires with the confidence that performance will be maintained, ensuring we provide our physicians with consistent, fast access to medical records.”

Silos Belong in the Scrapyard

Another hospital that has benefited from centralized storage is Tokushima University Hospital (TUH). As a university hospital responsible for providing health-care services to Japan’s Tokushima Prefecture, it has a legal requirement to store certain data and images for a period of time, meaning a greater need for long-term storage than a regular nonteaching hospital.

“Our Data volumes will continue to increase as we become more reliant on technology systems to support diagnosis and treatment,” says Ken’ichiro Shimai, Deputy Director, Medical IT Center, TUH. “New CT and MRI modalities mean huge volumes of image data, added to the images already produced by the cardiovascular, endoscopy, ultrasound, and surgery departments. There volumes of data are growing year-on-year.”

TUH’s IT infrastructure initially comprised between 70 to 100 silo systems, which made it difficult to access patient records easily.

Consider a car chase in Mad Max, and how the protagonists urgently need to reach for a weapon to shake the villains off their tail, but have no idea which car compartment it is in. Information, in the medical context, is a powerful weapon. The ease of accessing it greatly increases the chances of a patient’s survival.

After implementing a similar EMC Isilon X200 storage system, TUH has successfully moved away from its silo-based data systems onto one of centralized management and control, enabling all medical data to be digitized and stored centrally. This ensures patient records remain immediately accessible to medical personnel to assist them in prescribing the most appropriate treatment.

Backup to the Future

In an article by Financial Times, it discusses how the ability to monitor health indicators constantly – through devices such as wearables – rather than periodically during check-ups can be considered new medicine. These constant data flows may yield insights that force physicians to rethink the way they treat their patients. It’s safe to say that the storage and interpretation of medical data will play an increasingly vital role over the next few years.

Wilhelm Konrad Roentgen, Professor of Physics in Worzburg, Bavaria discovered X-Rays in 1895 by observing and deducing an accidental exposure of energy from his early design cathode ray tube onto a photographic plate. The first X-Ray was of his wife’s hand, shown below. X-Rays are one of the earliest great discoveries of the post-Renaissance age, even before E=mc2. Radiological Society of North America (RSNA) has been the definitive gathering place for the future of Radiology and Healthcare technology for as long as I can remember. X-Rays and its cousin spectra drive most of the new innovations in instrumentation, process and informatics.

XrayThe Western Roentgen Society, a predecessor of the RSNA, was founded in 1915 in St. Louis, Missouri. RSNA celebrated its centennial last year in Chicago (the anchor city for the conference for a long time). An interactive timeline of RSNA and Radiology events can be seen here.

I broke my almost 18-year attendance hiatus after my RSNA Associate membership acceptance this year; I started my career building X-Ray machines many, many moons ago and have worked in most Radiology modalities.

Technology Highlights:

The scale of the conference was impressive, as has always been. The Technical and Exhibition Hall was massive at the McCormick Place Conference Center in Chicago. With about 670 exhibitors (105 new exhibitors) and the “who’s who” anchors like Bayer, Canon, CareStream, FUJIFILM, GE, Hitachi, Hologic, McKesson, Philips, Samsung, Shimadzu, Siemens, Terarecon and Toshiba this year’s technology innovation highlights were:

  • GE 1.5 Tesla and 3 Tesla MRI (Magnetic Resonance Imaging) instrument with Total Digital Imaging (TDI) as well as CardioVascular Ultrasound systems with HDlive.
  • Siemens 3D Advanced Visualization software, Cloud-based imaging network and xSPECT (Single Proton Emission Computed Tomography) for bone scans along with the combination of MRI-PET and PET-CT modalities.
  • Virtual Reality (True3D), 3D printing, Human Connectome, Machine Learning and Deep Learning.
  • RSNA Image Share, a Provider and Patient service.
  • The maturing of Vendor Neutral Archives (VNA).

Plenary sessions:

On Monday November 30th, the “New Horizons Lecture: Redefining Innovation” was delivered by Jeffrey R. Immelt, Chairman and CEO of GE. Mr. Immelt made the point that GE was both in the instrumentation innovator (US$20B) and payor (US$2.5B) revenue streams in healthcare. He emphasized that improving the ecosystem (consumerism + access, chronic disease outcomes, lower cost and behavior changes) as well as sustaining innovation (neural MRI, decision support, image guided interventions, automated image analysis and productivity) were its guiding principles. Precision Medicine, integration of Radiology with Pathology, cell therapy using Bioprocessing, mobile technologies at global scale and analytics were the central innovation themes for GE.

On Tuesday, December 1st, Dr. James H. Thrall, Chairman Emeritus, Department of Radiology at Massachusetts General Hospital, delivered the “Annual Oration in Diagnostic Radiology: Trends and Developments Shaping the Future of Radiology”. He outlined three themes: imaging technologies, infrastructure and information/communications systems, and the application of the imaging correlates of precision medicine. Dr. Thrall presented a Venn diagram of all imaging modalities. The various inter-modal intersection sets were highlighted with specific mention of PET-CT-MRI and the work of Dr. Ge Wang and Omni-Tomography was highlighted as shown in the figure below:

Omni Tomography

Of particular note to me was the official entry of “Precision Medicine” into the RSNA lexicon. This is the first year I have heard of the term “RadioGenomics” and “RadiOmics” in a major conference (first mentioned by Andreassen et al in 2002). Dr. Thrall made it a point to mention shorter acquisition times and lower radiation dosage to the patient.

Dr. Ronald Arenson, RSNA President, introduced both plenary speakers.

Academic Sessions:

My focus for the 2015 Academic sessions was Informatics. Here are the condensed highlights:

Dr. Charles Kahn (U Penn) and Dr. Bradley Erickson (Mayo) led the inaugural “Year in Review” for Imaging Informatics. This session was jointly sponsored by RSNA, AMIA (American Medical Informatics Association) and SIIM (Society for Imaging Informatics in Medicine). The format was a dense, rapid-fire summary of key topics for 2015 as well as the seminal journal articles on various topics, which were the foci of other informatics sessions:

“The Text Information Extraction for Radiology Reporting” session presented techniques using NLP, Machine Learning and Deep Learning. A majority of radiologists would like to see structured reporting. The tools mentioned were OpenNLP, Mallet, cTAKES, eHOST, VINCI ChartReview and NCBO Annotator.

One of the more useful “hands-on” sessions that I attended was “Radio-Genomic Research: Accessing Clinical Imaging-Genomics-Pathology Data from Public Archives-The Cancer Imaging Archive” led by Dr. C. Carl Jaffe and Dr. Fred W. Prior. The Cancer Genome Atlas (TCGA) data portal is well known in the Genomics. The NIH has now created The Cancer Image Archive (TCIA) which has specific deidentified images for integrating Radiology with Genomics.

There was an entire morning session devoted to “Digital Information Security and Medical Imaging Equipment” which covered the instrumentation layers, protocols and regulations in some detail. It is interesting to note that Radiology Imaging client applications are still using OSx as the primary platform, with some “hands-on” sessions for DICOM not using other OSes at all. It is time for a web service based imaging application to come to the fore.

I strongly believe that integrating (and interoperating with) Radiology and Pathology phenotypic moieties into Genomics knowledge will be the real catalyst for the adoption of Genomics as an early clinical test (which is getting more complex by the month). Oh, and let’s not forget Proteomics. If multi-modal Radiology becomes reality soon (especially PET-CT-MRI), using biomarker-guided imaging, the data generated and the analytics required both grow exponentially. We are getting to that unified “Healthcare Data Lake” as shown below:

EMC Healthcare

RSNA is now one of the top two academic conferences in the United States (and maybe worldwide) with a 2014 attendance of about 57,000. The 2015 attendance dropped, with registered attendants numbering about 48,000 (as of this writing). Here is hoping for more radiologists, technologists, innovators and patient advocates for this year’s RSNA!

Stay warm and healthy!
