Background
![Page 4: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/4.jpg)
The Nature of Society
• Ageing Society• Chronic disease is the norm• Multiple chronic diseases are very common in
the older adult• Plurality of service providers and a plurality of
services• Increasingly blurred line between participation,
disability, impairment and prevention services eg Health and Social Services

What are NHS information Standards?
• NHS Information Standards are information and communication technologies which achieve interoperability between independent computer systems [functional interoperability] and between independent users particularly patients, clinicians, and managers [semantic interoperability]

Business Requirements
![Page 9: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/9.jpg)
Patient as a Partner
• Language is as vital to the physician’s art as the stethoscope or the scalpel. A doctor begins by examining the words of his patient to determine their clinical significance. He then translates the words into medical language, describing how the condition came to be, what it means, and how it may evolve. Of all the words the doctor uses, the name he gives the illness has the greatest weight. It forms the foundation of all subsequent discussion, not only between doctor and patient but also between doctor and doctor and between patient and patient.– Groopman J. Hurting all over. New Yorker 2000;13 Nov:78.
![Page 10: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/10.jpg)
Patient as a Partner
• Expert Patient: Patient as an ‘actor’: caring & making decisions about their own health
• Patient Choice: Patient access to information and knowledge to make choices
• Customisation of care based on patient needs and values
• Patient as the source of control• Patient should have unfettered access to their
own health data– NHS Policy and from IOM report: Crossing the Quality
Chasm: A new Health System for the twenty first millennium
![Page 11: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/11.jpg)
Digital Environment
• Maximise automatic processing by computers• Minimise human translation and re-recording• Be present and effective at the point of care where ever
that may be!• Be maintained and perform as a safety critical system in
line with ITU or theatre• Support a low training overhead• Integrate and different applications be almost seamless
to the user• Must support high information usefulness
Shaunnessy Equation: Usefulness = relevance x validity / work to get it
![Page 12: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/12.jpg)
Prime Purpose is Patient Care
• Support– Detailed note keeping by clinicians– The faithfulness of the notes over time and across various
systems eg content and context– The ordering and scheduling of activities for patient care– The incorporation of investigation and other results– The incorporation of patient input– Communication between clinicians; clinicians and patients– Best professional record and communication practice– Legal and Regulatory scrutiny– Complaint investigation eg have a clear audit trail– Knowledge and decision support
![Page 13: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/13.jpg)
National Value Added [Secondary] Services
• Derived automatically from the record if at all possible– Payment of individuals or organisations– Accreditation/Appraisal of individuals or organisations– Public Scrutiny of existing policy by government or
agents– Informing new policy– National monitoring; performance; natural disaster etc– Epidemiological research
![Page 14: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/14.jpg)
New Actors
• Some Computer Applications are ‘Actors’
• These are agents which undertake transformations/activities
• Examples would include:– Decision Support Services– E-Care Pathways etc
An e-Care Pathway is a machine based resource which can be used in the electronic record by the clinician and patient to derive a situationally specific plan for a given patient assuming the current state of knowledge
![Page 15: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/15.jpg)
Information and Data Requirements
![Page 16: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/16.jpg)
Perspectives on Information
• Requirement in the machine environment for the three perspectives to integrate– Patient Specific: The information necessary
for the care of an individual citizen– Knowledge-Based: The information derived
from the scientific knowledge base– Secondary uses: The information used for
supporting analysis and decisions on policy, performance and populations
![Page 17: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/17.jpg)
Data: ‘Uniform Data Standards’
• According to NCVHS (2000), essential features include– Interoperability – any data source must be able to exchange data with any other– Data comparability – meaning of data must be consistent [Public; Team; Profession; Discipline]– Data quality – data must be collected consistently, reliably, etc.
• Medicine should have “fewer words, more meaning” like air traffic controllers and military– (Voytovich, 1999)
![Page 18: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/18.jpg)
Significant Safety Component
• Data standards are only effective when implemented effectively:– Appropriate choice of standard– Effective incorporation into systems– Effective deployment of systems in the work
place [or robust and reliable work-rounds]– Effective staff/clinical use– AND standard safety testing at all stages
![Page 19: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/19.jpg)
Information Standards recommended
![Page 20: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/20.jpg)
Patient Record Access Standard
• Two Health Record and Communication Practice Standards
• Sharing Standard (Example)– Everything in or from a patient’s record including
communications should be shared with them in real time– The only exceptions should be explicitly stated professional
standards and/or legal requirements
• Issue Resolution Standard– Error management [Patient and clinician agree wrong]– Conflict management [One partner agrees one disagrees]– Disclosure issue [clinician feels x should be disclosed patient
feels it shouldn’t]
![Page 21: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/21.jpg)
Why share a core record with the patient
• Reg Berkshire, a patient who sat on The Copying letters to patients work group, said "getting bad news is bad; getting it late is worse".
• When would you want to find out what was wrong with you?– Richard Fitton 01.11.05
![Page 22: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/22.jpg)
Patient Record Input Standard
• Health Record and Communication Practice Standard– Patients should be able to input directly into their own
records concerning preferences and choices– Patients should be able to input directly into their
record the data that has been accumulated through competent collection and input
– Exceptions would include those captured in law and/or those published by or through Regulatory Bodies eg those lacking capacity
![Page 23: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/23.jpg)
Health Record and Communication Practice Standards
• Some national professionally endorsed and citizen understood standard definitions for record terms with:– Primary and secondary uses– Needed Nationally– Could be subject to perverse behavioural
incentives
• Examples: Myocardial Infarction & Diagnosis
![Page 24: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/24.jpg)
Health Record and Communication Practice Standards
• Some Team and some profession based standards:– End dates; are you ever cured of cancer? Or
asthma?– Minimum communication content; what is
someone’s current medication?– Uncertainty and laterality; are there any
professional constraints?
![Page 25: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/25.jpg)
Data Content Standards
• Common Terminology both for clinical content and also for the health system [SNOMED CT plus Dictionary Medicines and Devices (DM&D) plus ?]
• Professional and Technical Standard for grammatically constrained clinical phrases or several standards that are machine recognisable and interoperable. {Pre-co-ordination, post co-ordination [SMOMED CT]; Archetype methodology [ENV13606]; Clinical statement model [HL7 v3].
![Page 26: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/26.jpg)
Data Content Standards
• Standard set of units and values eg UCUM• Method for representing complete aliquots of
information ie those components that are signed as a single entity– Scales– Measures– Progress note entries– Clinical Documents
• Results• Communications
![Page 27: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/27.jpg)
Temporal Abstraction Standards
• The temporal abstraction is a knowledge model which has to interact with the terminology concept model and the record model(s)
• There are three types of temporal abstraction– Calculated Abstraction– Subsumption abstraction [eg all types of asthma]– Inference Abstraction [eg probable asthma and those with
nocturnal wheeze]
• A common way of expressing the data required for another purpose:– A Central Return– A National Audit– A payment system based on care
![Page 28: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/28.jpg)
Potential Components of a Temporal Abstraction
• A specific Temporal Abstraction could have:– A name– Components:
• Data item• Information type [linked to record model]• Defining human readable expression• Defining machine readable expression based on the national
terminology eg SCT and specific associations eg directory content and any clinical phrases as expressed in the logical record model
• Process for computation• Associated Professionally endorsed and citizen expected
definitions [if different from those in the human readable expression above]
![Page 29: Information Standards and Chronic Disease Management Professor Martin Severs FRCP FFPHM](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d625503460f94a44ec3/html5/thumbnails/29.jpg)
Other Standards
• Communication Standards: HL7 V3• Information Governance standards: care record
guarantee• At national level with a plurality of service
providers and a need for safe, effective, timely and appropriate implementation. There is a growing body of opinion that suggests one needs a common method for expressing data requirements that will interoperate with any physical data architecture– A Logical Record Model
