Health care wants Linked Data, a semantic web of taxonomies and patient information that empowers patients, doctors and researchers. Hoot72, a straightforward way to break into the silo's of today, is a key step to get there.
Just Clicking Through: How Instructors Use Sakai as a Web PortalSteven Lonn
It is well known that the "typical" instructor uses online management systems to distribute course materials and make announcements. What has not been explored is how instructors use these systems to link to the vast array of educational content and resources available through the Internet. Which types of websites are most common? For which disciplines? How does an instructor choose which content is the "best" or most relevant for their course?
This session will present how instructors at residential and commuter campuses of the University of Michigan used the Web Content and Resources tools in Sakai to link to Internet resources. The different categories of resources as well as differences between campuses, disciplines, and departments will be discussed. Session participants will be asked to reflect on these findings and discuss implications for connecting instructors to "reliable" resources, and how to potentially scaffold instructors' selections of external resources in Sakai OAE.
Investigating Changes in Integrative and Lifelong Learning: Students’ Use of ...Steven Lonn
For the past two academic years, the ePortfolio team at the University of Michigan has administered pre and post surveys to students that were using ePortfolios for the purpose of fostering integrative, lifelong, and lifewide learning. This session will present results from this longitudinal research, focusing on specific trends, significant findings and implications of this research for conducting integrative assessments of students' academic and co-curricular learning.
The document presents several lists of three things related to life. It discusses things that once gone never return like time, words, and opportunity. Positive things that should be had are hope, peace, and honesty. The most valuable things are love, friends, and self-confidence. Things that can destroy a person are pride, greed, and anger. God, faith, and hope are presented as things that can save a person. The document encourages passing the message along to others.
Throw the Semantic Web at Today's Health-carehoot72
Health-care needs functioning IT - and there is finance available. Yet still, it lumbers along, mired in the same talking points: we need Portable Health Records; we need to exchange clinical care information; we need fuller descriptions. Is the Semantic Web the answer? Can it get to work right now?
This document summarizes a presentation by Dr. Elizabeth Langran and Dr. Janine Dewitt from Marymount University on mobile mapping and place-based learning approaches. It discusses using mobile devices and geospatial technologies like GPS, GIS maps, and geotagging to have students conduct mapping projects to learn about their community. Examples are given of projects conducted by high school, undergraduate, and graduate students. It also introduces some geospatial tools like Ushahidi Crowdmap, ESRI ArcGIS Online, and Google Maps that can be used and provides information on contributing to an online map being created for the conference.
Analytics Collaboration Session at Sakai 2011Steven Lonn
Academic Analytics is a hot topic in Higher Education. Institutions are seeking to use analytics to understand student success and academic performance, maximize retention. Increasingly, regulatory and accreditation bodies require this information to help measure effectiveness. This block session will report on a number of analytics initiatives within the Sakai Community, and higher education generally. Opportunities will be provided to interact with individual presenters, and to synthesise information available across the session.
Hoot72 throws light on a health-care facility's care-process. It transfers clinical data into the Semantic Web from HL7 messages being exchanged by Health-care applications.

Hoot72 throws light on a health-care facility's care-process. It transfers clinical data into the Semantic Web from HL7 messages being exchanged by Health-care applications.
Presented at CDISC 2009 in Baltimore, it explores what the Semantic Web can bring to Healthcare. Can it be deployed right now? With ease? CDISC sets standards for the exchange of clinical trial data. Once deployed, they remove much of the redundancy and paper processing that characterizes a typical trial today. Its membership includes government regulators like the US FDA, all the major drug companies and their IT vendors.
During the last two decades Clinical Decision Support (CDS) standards and technologies have progressed significantly to develop them as more robust and scalable systems. However, the current context of medicine sets high demands in aspects such as interoperability to enable the use of EHR data in CDS systems, the need to establish communication challenges to include the patient as an active component in decision making, collaborative learning and sharing CDS systems across institutional borders, to name a few.
In this thesis I tackle some of these challenges. In particular, I evolve previous conceptual computerized decision support frameworks and I postulate a CDS systems environment where different models interact to enable:
• Secondary use of data for CDS systems: The dissertation presents a model to leverage different developments in data access and standardization of medical information. The result is an openEHR-based Data Warehouse architecture that enables access, standardization and abstraction of clinical data for CDS systems. The architecture allows: a) to access heterogeneous data sources; b) to standardize data into openEHR to grant interoperability of data; and c) to exploit an openEHR repository as a Data Warehouse that allows querying data in a technology-independent format (the Archetype Query Language).
• CDS systems semantic specification: The semantic model proposed exploits the paradigm of Linked Services to unambiguously describe CDS systems in a machine- understandable fashion. This grants ontological descriptions of functional, non- functional and data semantics. These descriptions facilitate to overcome some of the barriers in CDS functionality sharing. In particular, the semantic model proposed allows using expressive queries to discover CDS services in health
III
networks, and analyzing CDS systems interfaces to understand how to interoperate with
them.
• Effective patient-CDS systems interaction: the dissertation proposes a method to
evaluate the communication process between patients and consumer-oriented CDS systems. The method aims for detecting if important human-computer interaction barriers that could lead to negative outcomes are present in CDS systems user interfaces.
The document discusses healthcare challenges and the evolution of healthcare information technology (HCIT). It notes that chronic diseases account for over 75% of US medical costs. It also describes different levels of HCIT integration, from legacy systems to continuum-focused systems using standards-based structured data. The document advocates for an approach using a Global Clinical Data Archive to provide seamless interoperability and transparency of clinical data across the healthcare system.
Medical Leadership: Complex Systems: Open PlatformsTony Shannon

21st Century Healthcare
Need for Medical Leadership
The Challenge of Complex Systems
The Promise of Open Platforms
This document provides an overview of system interfaces and integration in health IT. It discusses the importance of integrating disparate healthcare systems to ensure interoperability. Interface methods like point-to-point connectivity and interface engines are described. The document also outlines the HL7 standard, which is widely used for communication between EHR components. HL7 messages use groupings of segments to relay information in near real-time. Finally, the summary discusses health information exchanges that act as interface engines between healthcare institutions in a region.
The document discusses the progress of the ICD-11 revision. It notes that the beta version is currently frozen for review and field trials, with over 75% of top-level categories defined and errors reduced. Field trials will assess the applicability, reliability and utility of ICD-11 for purposes like mortality and morbidity coding. The revision aims to create an electronic, multilingual classification to facilitate health information exchange.
Next generation electronic medical records and search a test implementation i...lucenerevolution
Presented by David Piraino, Chief Imaging Information Officer, Imaging Institute Cleveland Clinic, Cleveland Clinic
& Daniel Palmer, Chief Imaging Information Officer, Imaging Institute Cleveland Clinic, Cleveland Clinic
Most patient specifc medical information is document oriented with varying amounts of associated meta-data. Most of pateint medical information is textual and semi-structured. Electronic Medical Record Systems (EMR) are not optimized to present the textual information to users in the most understandable ways. Present EMRs show information to the user in a reverse time oriented patient specific manner only. This talk discribes the construction and use of Solr search technologies to provide relevant historical information at the point of care while intepreting radiology images.
Radiology reports over a 4 year period were extracted from our Radiology Information System (RIS) and passed through a text processing engine to extract the results, impression, exam description, location, history, and date. Fifteen cases reported during clinical practice were used as test cases to determine if ""similar"" historical cases were found . The results were evaluated by the number of searches that returned any result in less than 3 seconds and the number of cases that illustrated the questioned diagnosis in the top 10 results returned as determined by a bone and joint radiologist. Also methods to better optimize the search results were reviewed.
An average of 7.8 out of the 10 highest rated reports showed a similar case highly related to the present case. The best search showed 10 out of 10 cases that were good examples and the lowest match search showed 2 out of 10 cases that were good examples.The talk will highlight this specific use case and the issues and advances of using Solr search technology in medicine with focus on point of care applications.
The document discusses the design principles and challenges of clinical information systems at AZ-VUB hospital in Belgium. It outlines the hospital's IT strategy of using a multi-layered, component-based architecture across the entire hospital. Key challenges discussed include developing clinical decision support systems, managing workflows, and addressing issues around data storage and mobility.
This document provides an overview of HL7 standards. It begins with introducing Thailand's certified HL7 specialists and then discusses why standards are important for health information exchange. The document explains different levels of interoperability and describes various HL7 standards including HL7 v2, HL7 v3, and CDA. It highlights key differences between HL7 v2 and v3 and provides examples of HL7 message segments.
This document provides an overview of HL7 standards. It discusses HL7 version 2 and version 3 messaging standards, as well as the Clinical Document Architecture (CDA). HL7 version 2 is the most widely implemented healthcare data exchange standard. Version 2 uses a pipe-delimited format while version 3 uses XML and is based on the Reference Information Model (RIM). The RIM defines common data types and allows semantic interoperability. The document also notes some challenges with implementing version 3.

- Dr. Tony Shannon is a consultant in emergency medicine and chief clinical information officer at Leeds Teaching Hospitals who advocates for connecting healthcare through open standards and open source technology.
- He argues that healthcare needs an open platform approach integrating people, processes, and information technology to overcome current challenges of disconnected systems and closed solutions.
- In Leeds, they are developing an open standards-based electronic patient record system using openEHR archetypes that will integrate data across primary, secondary, social and mental healthcare to improve outcomes.
Hl7 Standards, Reference Information Model & Clinical Document ArchitectureNawanan Theera-Ampornpunt
This document discusses HL7 standards and includes information about:
- HL7 version 2 (HL7 v2), which is the most commonly used HL7 standard for defining electronic messages supporting hospital operations.
- HL7 version 3, which adds semantic capability to messaging.
- The Clinical Document Architecture (CDA), which defines the structure and semantics of clinical documents.
HL7 is an organization that develops standards to enable interoperability in healthcare. It has progressed through several stages, starting with simple messaging and expanding to include documents, services and an enterprise architecture framework. IHE builds on standards by providing implementation guides to integrate multiple standards in real-world use cases. What's hot includes CDA documents and SAEAF, while standards adoption remains a challenge.
At Elsevier, a lot of effort is focussed on content discovery for users, allowing them to find the most relevant articles for their research. This, at its core, blurs the boundaries of search and recommendation as we are both pushing content to the user and allowing them to search the world’s largest catalogue of scientific research. Apart from using the content as is, we can make new content more discoverable with the help of authors at submission time, for example by getting them to write an executive summary of their paper. However, doing this at submission time means that this additional information is not available for older content. This raises the question of how we can utilise the author’s input on new content to create the same feature retrospectively to the whole Elsevier corpus. Focusing on one use case, we discuss how an extractive summarization model (which is trained on the user-submitted summaries), is used to retrospectively generate executive summaries for articles in the catalogue. Further, we show how extractive summarization is used to highlight the salient points (methods, results and finding) within research articles across the complete corpus. This helps users to identify whether an article is of particular interest for them. As a logical next step, we investigate how these extractions can be used to make the research papers more discoverable through connecting it to other papers which share similar findings, methods or conclusion. In this talk we start from the beginning, understanding what users want from summarization systems. We discuss how the proposed use cases were developed and how this ties into the discovery of new content. We then look in more technical detail at what data is available and which methods can be utilised to implement such a system. Finally, while we are working toward taking this extractive summarization system into production, we need to understand the quality of what is being produced before going live. We discuss how internal annotators were used to confirming the quality of the summaries. Though the monitoring of quality does not stop there, we continually monitor user interaction with the extractive summaries as a proxy for quality and satisfaction.

This document discusses myths and facts about big data in healthcare and proposes an innovation in healthcare IT standards called Multilevel Healthcare Information Modeling (MLHIM) to address some limitations of traditional standards. MLHIM uses XML schemas rather than ADL to define clinical concept constraints in a bottom-up way. This allows for multiple definitions of a concept and makes the standards more adaptable to big data. Tools are being developed to generate, edit, and work with MLHIM clinical models to facilitate reliable big data collection and interchange.

• Health Data in “islands”, “bunkers”
• Admissions/Pharmacy/Lab ... Systems
• But the Systems do chat (internally)
• “Patient Arrival ...”, “Observation made ...”
• A stew of HL7 v2.x messages
• Billing data does leave the premises!

System-wide
HL7 v2 only “suggests” - too messy for^integration!
7. Disintegrated!
• Full integration costly
• custom models, brittle
• only stray outside when forced
• (Today’s) Web veneers
• for men, not machines
• Another Option? ...
8. HL7 v3 - the Fix?
• HL7 v3 - Object-based
• End 2005, a do over, ten years in the making
• Object Model (RIM), not V2-compatible
• Bonus: XML goodness
• Beyond Interface - Common Model
• Modern systems to be “RIM-Inside”
• Remake all systems
9. But ...
“Frozen interface syndrome: existing HL7
message interfaces are pretty much stuck at 2.2.
Meaning that application vendors don't like to
change for change's sake -- there needs to be a
business motivation.”
-- Wes Rishel, Gartner Group
• Government Mandate (UK), some green field
• Just another opportunity to gateway
• Just polite talk? Are we stuck?

• Stuff and Codes, Codes, CODES!
• Messages (v2 or v3) just “trucks”
• If Codes a mess then ...
11. State of the Codes
• For substances, procedures, diseases ...
• Local, National, International; Care vs Billing
vs ...
• SNOMED CT, MeSH, ICPC, ICD-9-CM, DRG,
MDC, LOINC, CPT-4, HCPCS Level II, ICD-10,
HL7 Vocabulary Domains ...
• Too many, unwieldy, overlapping ...
• Extend, (re)structure, link
12. “In” Schemes
Scope Size Grain C/E*
SNOMED All 350K Varies C
LOINC Labs 50K? High C
NDC Drugs 11 Digits High E
ICD9-CM Diseases 10K? Low*** E
UMLS All** Combined Varies Varies
* Composed or Enumerated
** Assumes diversity. UMLS is 143 others: “not an attempt to build a single standard biomedical vocabulary.” RxNORM is its drugs.
*** “Other” is a catch-all, mandated for medicare billing
13. Focus: Coverage
• Problem List to SNOMED: “SNOMED CT ... can
exactly represent a large portion (92.3%) of the
terms” -- Mayo Clinic
• Local Lab Codes to LOINC: “Almost 19% of
LOINC codes are ‘other’” -- CDC
• LOINC to SNOMED: “Automatic mapping of
laboratory procedures from LOINC to SNOMED
CT remains incomplete and unsatisfactory” --
Mapping Issues, Olivier Bodenreider, MD, PhD
14. Elephant: Equivalence
there may be several different ways to express the same concept. Human users may be
able to recognise that these are essentially the same, but the rules for doing so must be
made explicit to be usable by computer.
-- Why is Terminology hard?, Alan Rector
• Finding vs Observable
• [serum_potassium_elevated_code] vs [Code: serum_potassium_code Value: elevated]
• Many and one
• “head injury” and “no intracranial bleed” vs “head injury without intracranial bleed”
• Little/No Lexical match
• “colon cancer” vs “malignant neoplasm” plus “primary site: colon”
• Beyond Equivalence - kind-of
• BrCA Breast Cancer, Cystic Fibrosis ... are Diseases-linked-to-Genes
15. Where’s the Ontology?
• Ontology: “an implementable model of the
entities that need to be understood in common in
order for some group of software systems and
their users to function and communicate at the
level required for a set of tasks” -- Alan Rector
• Code schemes slight/none: “deficiencies in the
knowledge representation languages used”
• Enter w3c’s OWL == Web Ontology Language
• Focus on meaning referenced by codes
17. Joining the “Semantic Web”
• Web of documents to Web of data
• Reuse: HTTP, URIs
• Add: Query (SPARQL), Represent
(RDF), Meaning (OWL)
• Silo’ed to Meaningful Linked Data
18. W3c HCLS - Power of linkage
• Gap: Trial Criteria, Patients
• Patients taking “Weight Loss Drugs”
• Patient NDC codes: DESOXYN TABLETS
(00074337701) ...
• Linked by Ontologies
• "may_treat" “Obese” to RxNORM
• RxNORM links in NDC codes
• Trial meets Patients in two steps
