      <p>OPERATION: Populate Questionnaire</p>
      <div>
        <p>Generates a 
          <a href="questionnaireresponse.html">QuestionnaireResponse</a> instance  based on a specified 
          <a href="questionnaire.html">Questionnaire</a>, filling in answers to questions where possible based on information provided as part
           of the operation or already known by the server about the subject of the 
          <a href="questionnaire.html">Questionnaire</a>.
        </p>

        <p>If the operation is not called at the instance level, one and only one of the identifier,
           questionnaire or questionnaireRef 'in' parameters must be provided. If called at the instance
           level, these parameters will be ignored.</p>

        <p>The response will contain a 
          <a href="questionnaireresponse.html">QuestionnaireResponse</a> instance based on the specified 
          <a href="questionnaire.html">Questionnaire</a> and/or an 
          <a href="operationoutcome.html">OperationOutcome</a> resource with errors or warnings.
        </p>

        <p>The 
          <a href="questionnaireresponse.html">QuestionnaireResponse</a> instance will be populated with an unanswered set of questions following the group and
           question structure of the specified 
          <a href="questionnaire.html">Questionnaire</a>.  If  
          <em>content</em> parameters were specified or the 
          <em>local</em> parameter was set to true, some of the questions may have answers filled in as well.
            In the case of repeating questions or groups, typically only one repetition will be provided
           unless answer values exist that would support populating multiple repetitions.
        </p>

        <p>Population of the 
          <a href="questionnaireresponse.html">QuestionnaireResponse</a> with appropriate data is dependent on the questions and/or groups in the 
          <a href="questionnaire.html">Questionnaire</a> having metadata that allows the server to recognize the questions.  This might be through
           
          <em>Questionnaire.group.question.code</em>, through extensions such as the 
          <a href="extension-questionnaire-dereference.html">http://hl7.org/fhir/StructureDefinition/questionnaire-deReference</a> extension or through use of the 
          <a href="conceptmap.html">ConceptMap</a> resource.
        </p>

        <p>Regardless of the mechanism used to link the questions in a questionnaire to a &quot;known&quot;
           mappable concept, solutions using this operation should ensure that the details of the
           question and associated linkage element are sufficiently similar as to safely allow auto-population;
           i.e. the question text and context must be sufficiently the same, the value set for the
           question must fall within the value set for the mapped element, the data types must be
           the same or convertible, etc.</p>

        <p>While it is theoretically possible for a

           of this transaction is merely to reduce redundant data entry.  A client 
          <strong>SHOULD</strong> ensure that a human submitter has an opportunity to review the auto-populated answers
           to confirm correctness as well as to complete or expand on information provided by the
           auto-population process.
        </p>

        <p>When creating an &quot;empty&quot; questionnaire, the general algorithm is to create a
           QuestionnaireResponse with one item for every item in the source Questionnaire, including
           items with &quot;enableWhen&quot;, &quot;display&quot; items, etc.  If a question has
           a default, the default answer should be populated.  And the QuestionnaireResponse should
           point back to the originating Questionnaire.  Repeating items will typically only include
           a single repetition.  Other extensions and/or</p>

        <p>Complex form designs with conditional logic or tight constraints on cardinalities may
           be challenging to auto-populate.  A server MAY choose to traverse the questionnaire as
           if it were a human respondent, answering only those questions that are enabled based on
           previously answered questions.  However, doing so may result in minimal population.  Alternatively,
           systems may choose to populate all known answers, independent of dependencies and other
           constraints.  This may cause questions to be answered that should not be answered.  It
           will be up to the client to appropriately prune the final populated questionnaire once
           human review has taken place.</p>

        <p>Invoking this operation with the ''content'' parameter may involve the disclosure of personally
           identifiable healthcare information to the system which is performing the population process.
            No such disclosures should be made unless the system on which the operation is being
           invoked is a &quot;trusted&quot; system and appropriate agreements are in place to protect
           the confidentiality of any information shared with that system.</p>
