Continua Questionnaire Use Case

  • Continua Questionnaire Use Case

  • Sample Questions

  • Workshop with Lantana on the Realization of Continua Requirements

    • Options
    • Results
  • Discussion and next steps









Question Set

  • Question Set

    • It groups questions related to a domain e.g. mental well-being.








A question may also hold link to a multimedia item (e.g. image, video)

  • A question may also hold link to a multimedia item (e.g. image, video)

  • A question may also consists of attributes that are used to signal the minimum and maximum number of answer option a patient must select (similar to ObservationRange construct)



The answer to a question may be of numeric type.

  • The answer to a question may be of numeric type.

  • Allowed range of values (e.g. 0 to 24) for an answer can be indicated using the ObservationRange construct.



Three day workshop with Lantana development team where we discussed Continua use case and requirements (slide 6-10) and then developed a small prototype.

  • Three day workshop with Lantana development team where we discussed Continua use case and requirements (slide 6-10) and then developed a small prototype.

  • After several hours of discussion we agreed to focus on the following system diagram:



As a result of the three day workshop we identified the following options for expressing the Questionnaire Document in a standard format

  • As a result of the three day workshop we identified the following options for expressing the Questionnaire Document in a standard format

  • Options



NOT a clinical document, used to extract the input from patient resulting in a response document

  • NOT a clinical document, used to extract the input from patient resulting in a response document

  • Extended the Questionnaire Assessment templates

  • If we go with CDA Extension option, then

    • Observation/code holds the question text
    • Observation/value holds the answer option(s)
    • Answer may be constrained as free text, an integer or multiple-choice expressed as a coded value set
  • Some questions include logic (pre condition- slide 9) that determines what question is shown next depending on the answer(s) to previous questions.

    • HL-7 Example
      • If observation/value in template A is “X-SOME-CODE” from LOINC, then template B is required
    • Continua equivalence
      • If the user answers question A with “SOME ANSWER”, then show question B next
    • We also looked at the HQMF IG
      • can be used to realize logical expressions (ex. a pre condition on slide 9)


We agreed that Questionnaire Response is a clinical document and can be easily mapped to CDA constructs similar to Questionnaire Assessment IG.
