  • system: urn:oid:1.2.208.184.100.1

  • code: RAL or GAL, for red alarm absolute reference range and yellow alarm absolute reference range, respectively.

Other reference range types, such as relative reference ranges, may be handled by another rule. If no absolute reference range is found, the rule causes creation of a single Task asking the clinician to assess the observation.

Info

Example relative reference range as -5 percentage point with reference base 90% for oxygen saturation measurement

The oxygen saturation measurement unit is expressed as percent (system=http://unitsofmeasure.org, code=%), the reference base likewise and in this case with a value of 90.

A red alarm relative reference range given as -5 percentage point would be given by a SimpleQuantity for the reference range’s low element with:

  • value=-5

  • unit=percentage point

  • system=http://ehealth.sundhed.dk/cs/ehealth-unit-code

  • code=percentagepoint

Thus, the rule would treat an Observation with value 85% as a red alarm case for this relative reference range and current choice of reference base with value 90%.

Assessment of TeleCare Nord COPD Questionnaire

This Library contains a rule that performs assessment of a QuestionnaireResponse which answers the Questionnaire TeleCare Nord COPD Questionnaire.

The rule contains two sets of question/answer value pairs:

  • A red trigger set of question/answer pairs

  • A yellow trigger set of question/answer pairs

During processing of the rule, all questions and answers in the QuestionnaireResponse are traversed and checked whether each particular question/answer pair is defined as a red and yellow trigger, respectively. When this is the case, the question/answer pair is added to internal bookkeeping in the form of a triggered red set and triggered yellow set, respectively. Ultimately, the triggered sets determine a priority as follows:

  • In case the triggered red set contains at least one question/answer pair, the priority is set to asap

  • In case the triggered red set is empty and the triggered yellow set contains at least one question/answer pair, the priority is set to urgent

  • Otherwise, the priority is set to routine

The Library has:

  • .type set to automated-processing

  • .parameter

    • .use set to in for input

    • .type set to QuestionnaireResponse

  • .parameter

    • .use set to in for input

    • .type set to Questionnaire

  • .parameter

    • .use set to in for input

    • .type set to ProcedureRequest

The Library rule sets up instructions that causes production of:

  • A ClinicalImpresssion:

    • .finding as follows:

      • If the triggered red set is not empty, a finding.item with a Coding:

        • system = http://ehealth.sundhed.dk/cs/clinicalimpression-finding-codes

        • code = red-question-answer

        • display = Rød spørgsmål/svar-kombination fundet i spørgeskemabesvarelse

      • If the triggered yellow set is not empty, a finding.item with a Coding:

        • system = http://ehealth.sundhed.dk/cs/clinicalimpression-finding-codes

        • code = yellow-question-answer

        • display = Gul spørgsmål/svar-kombination fundet i spørgeskemabesvarelse

      • If both triggered sets are empty, a finding.item with a Coding:

        • system = http://ehealth.sundhed.dk/cs/clinicalimpression-finding-codes

        • code = green-question-answer

        • display = Grøn spørgsmål/svar-kombination fundet i spørgeskemabesvarelse. Når anført som opsummering for hel spørgeskemabesvarelse er der ikke fundet røde eller gule spørgsmål/svar-kombinationer

  • A Task related to the ClinicalImpression with:

    • priority set to the priority value determined above.
