Laboratory IT Initiatives in SaskatchewanHL7 Regina Conference - June 7, 2001

  • Presentation Purpose is to discuss use of HL7 V3, not the Lab Standard itself

  • Vision for Electronic Test Requisition and Result Reporting

    • Provincial, not in-hospital/lab

    • presentation emphasis on CONTENT, not FORMAT

    • CONTENT:

      • HL7 V3 Reference Information Model

      • Use of Registries for content quality control

  • Strategy & Schedule

    • Leverage from British Columbia’s work on LOINC & HL7

      • Saskatchewan is reviewing the BC Standard and identifying areas of “difference” for resolution

      • Areas of difference include use of registries and associated governance models (e.g. assignment of new LOINC codes)

    • Partnership through the Western Health Information Collaborative (WHIC) & CIHI

Laboratory it initiatives in saskatchewan use of registries for data content

Laboratory IT Initiatives in SaskatchewanUse of REGISTRIES for Data Content

Overall Business Process Model: Registry Management Infrastructure

  • (Laboratory) Facility Registry

  • contains contact data for all Medical Laboratories in Saskatchewan

  • Planning for development internal to Saskatchewan? or WHIC?

  • a web-based Registry Management System associated with Laboratory Licensing

  • will require an “owner”, likely Lab Licensing/Quality Assurance

  • Service Recipient Registry

  • contains index of all identifiers used by all Sask stakeholders for all patients

  • Planning for development being led by CIHI and involves provinces, territories and Health Canada “jurisdictions

  • will require HL7 messages to be balloted

  • will require an “owner” not yet identified

  • Test Compendium Registry contains data for all Medical Tests done by all Labs in Saskatchewan

  • contains an index for all nomenclatures used by all Labs in Sask for Orders and Tests as well as LOINC codes for these tests

  • a web-based Registry Management System associated with Laboratory Licensing - a possible WHIC collaboration?

  • will require an “owner”, likely Lab Licensing/Quality Assurance

  • Service Provider Registry

  • contains index of all identifiers used by all Sask stakeholders for all Providers (individuals)

  • Planning for development being led by WHIC

  • will require HL7 messages to be balloted

  • will require an owner not yet identified

  • Project Deliverables - Design Phase:

    • Overall Business Data Model: Registry Management Infrastructure

Service Recipient Registry

There a 19 publicly funded jurisdictions that issue health cards with unique identifiers in Canada. There are an unknown number of internal (shadow) identifiers assigned by health delivery organizations, and an unknown number of identifiers issued by private 3rd party payors. One person may have several current identifiers presented during one or more care episodes.

Laboratory it initiatives in saskatchewan registry design

Laboratory IT Initiatives in SaskatchewanRegistry Design

  • Project Deliverables - Design Phase:

    • Overall Data Model: Registry Management Infrastructure

About 200 Labs in Saskatchewan are publicly owned and regulated by the Saskatchewan College of Physicians & Surgeons and are licensed by Saskatchewan Health. There are almost 230 Physician Office Labs in Saskatchewan. Saskatchewan needs to build a Registry Management System according to the guidelines of the HL7V3 RIM. This may be a feeder system to the WHIC Provider (Organization) Registry. It must, however, be closely tied to the Test Compendium Registry for licensing and information management purposes.

Laboratory it initiatives in saskatchewan registry design1

Laboratory IT Initiatives in SaskatchewanRegistry Design

  • Project Deliverables - Design Phase:

    • Overall Data Model: Registry Management Infrastructure

  • Several grouping levels of this data are required:

  • 1. Laboratory Licence Test Group

  • 2. A Test Panel/Battery (for both Orders & Instruments)

  • 3. A Named Test

  • 4. A specific Test/Result (LOINC)

  • HL7 refers to “Act Relationship”:

    • “A relationship between two acts. This includes numerous relationships, such as “part-of” relationships, which allow both temporal and non-temporal groupings of instances of acts. Examples include batteries of tests or longitudinal guidelines”

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions – manual systems using Web portal

Dr. Smith orders CBC on John Doe via Web portal – info verified by Web application using registries.

John Doe goes to LittleTown Lab – at Lab reception, info retrieved by Web application and collection recorded - sample numbered.

Sample taken to LittleTown Lab bench – info retrieved by Web application, sample processed and result recorded by Web application. Added info verified using registries.

Dr. Smith looks for John Doe result on Web and finds it.

Dr. Smith sends John Doe to Dr. Jones, a specialist. Dr. Jones looks on the Web portal for past lab test results for John Doe and finds the CDC result.

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions – computer systems using messaging

Dr. Brown orders cholesterol on Mary Doe from his practice management system – info verified by messaging to registries.

Mary Doe goes to Somewhere Bleeding Station –info retrieved and collection recorded by messaging - sample numbered.

Sample arrives at BigLab – info retrieved by LIS application through messaging, sample processed and result sent through messaging. Added info verified using registries.

Dr. Brown looks for Mary Doe result on his PMS and finds it along with a cholesterol fractionation done because cholesterol was high.

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions - mixed

Doctor uses the Web, but the Collection Point/Lab uses a computer system with messaging.

Lab test was done rurally using Web applications but is being found by another physician because the patient became sick when visiting town. The city physician has a practice management system.

Assumes the order and results exist in a central database or directory share by Web apps and HL7 messaging.

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions – validation early

Dr. White attempts to place an order and finds that the patient does not exist in the registry with the ID given to the doctor. He finds a ‘Richard Robin’, address in townA, in the registry, while he knows his patient as ‘Dick Robin’, address in townB. The patient confirms that he is the same person. Doctor changes his system to ‘Richard’ and the registry to the address in townB.

When patient arrives to have sample collected there is no problem with name or birth date.

Lab calls organism ‘E.coli’. System consults registry for agreed name ‘Escherichia coli’. Referral lab goes to registry to retrieve its name ‘E COLI’ before further lab work on the organism.

Assumes that all messages are validated before sending using the registries.

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions - help

Dr. Farout wants to order a very unusual test. His system does not list it, but he finds and orders it via the Web site rather than his PMS.

The patient goes to a collection center and they do not have the test on their system either. They use the Web site to find what has to be collected and where it must be sent.

The lab does not do this test without prior agreement with the physician on the merit of the circumstances. They decide to substitute another test and do the ordered test only if the substitute has an abnormal result. The lab cancels the ordered test and result (as normal) the substitute test with a comment.

The physician uses the comment info to access a paper on this group of tests and their interpretation on the Web portal.

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions – Completely Local

An intern orders a test on a patient in hospital directly into the hospitals LIS. Collection and reporting are also entirely within the LIS. The whole transaction can be reported to a central directory or database with a series of HL7 messages after the fact. The LIS will have to have the standards to make valid messages ‘after the fact’.

Alternatively, the hospital may use messaging to communicate between separate ward, collection and lab systems. A lab might even have a number of separate specialized lab systems rather than a single LIS and use messaging for input and output.


Laboratory it initiatives in saskatchewan hl7 regina conference june 7 2001

Laboratory IT Initiatives in SaskatchewanScenarios of Possible Laboratory Transactions – Incomplete testing

Dr. Black instructs a patient to go to a local hospital for a lab test and orders the test on the Web.

The patient decides he feels better and will not go for the test.

At some point, the central system can notify Dr. Black that his patient did not have the test done and cancel the order.

Or…

Before this, the patient may feel bad again and go to Dr. Green. The physician orders the same test and gets a message that there is an order with collection pending. There are many ways to resolve this situation depending on the physicians.
