Type Preview: Health assessment data types

ericgu — Fri, 11 Jul 2008 00:51:00 GMT

We have been working on supporting a Health assessment scenario, and are interested in your comments on the following new types.

The question-answer type is used to store a question that is asked and the answer to that question, and the health-assessment type is used to store an assessment based on a series of questions.

question-answer

This type stores the following information

Field name	Type	Comment
when	date-time	Date and time the question was asked
question	codable-value	The question that was asked. The question itself is stored in the text part of the codable value, and the question can be coded to a TBD questions vocabulary (or some other appropriate vocabulary).
answer-choices	codable-value (0..n)	The list of possible answers to this question. Questions that are answered using free-from text will not specify answer choices.
answers	codable-value (0..n)	The recorded answers. In many cases, the coding of the answer is identical to the coding of the selected answer-choices.

As part of our design process, we encoded a few questions using our current schema:

A simple question with a text answer:

<question-answer>
    <when>
        <date>
            <y>2001</y>
            <m>1</m>
            <d>1</d>
        </date>
    </when>
    <question>
        <text>How long has it been since your last physical?</text>
        <code>
            <value>LastPhysical</value>
            <family>wc</family>
            <type>medical-history-questions</type>
            <version>1</version>
        </code>
    </question>
    <answers>
        <text>about 3 years ago</text>
    </answers>
</question-answer>

A question with a yes/no answer:

<question-answer>
    <when>
        <date>
            <y>2001</y>
            <m>1</m>
            <d>1</d>
        </date>
    </when>
    <question>
        <text>Do you have fair skin?</text>
        <code>
            <value>SkinFair</value>
            <family>wc</family>
            <type>demographic-questions</type>
            <version>1</version>
        </code>
    </question>
    <answer-choices>
        <text>Yes</text>
        <code>
            <value>yes</value>
            <family>wc</family>
            <type>answer-yesno</type>
            <version>1</version>
        </code>
    </answer-choices>
    <answer-choices>
        <text>No</text>
        <code>
            <value>no</value>
            <family>wc</family>
            <type>answer-yesno</type>
            <version>1</version>
        </code>
    </answer-choices>
    <answers>
        <text>Yes</text>
        <code>
            <value>yes</value>
            <family>wc</family>
            <type>answer-yesno</type>
            <version>1</version>
        </code>
    </answers>
</question-answer>

A ‘check all that apply’ question:

<question-answer>
    <when>
        <date>
            <y>2001</y>
            <m>1</m>

Health assessment type

The health assessment stores the conclusion of an assessment. The type stores both an overall assessment (low risk of heart attack), and the supporting assessments that fed into that assessment.

Field Name	Type	Comment
when	date-time	The date and time the assessment was completed
name	string	The application’s name for the assessment
category	codable-value	The type of the assessment. Examples: Heart assessment, diabetes assessment, color cancer assessment. vocabulary: health-assessment-category
overall-results	Assessment	The overall assessment results. Examples: Heart attack risk, low risk
supporting-results	Assessment	Supporting assessments that contribute to the overall assessment. Example: High blood pressure, low risk.

Assessment type

Field Name	Type	Comment
name	codable-value	The name of the assessed area. Examples: Heart attack risk, high blood pressure
value	codable-value	The calculated value of the assessed area. Values may be coded using a specific set of values. Example: Low/Medium/High risk

We are seeing a growing amount of interest to store the details that make up a Health Risk Assessment (HRA) and would like to invite you to comment on this new data type request if your HealthVault integration plans include this type of information. In looking across the HRA data, there are three types of data where we are focusing our attention:

New data types and updates to existing data types - height, weight, BP are already available, but there may be others that should be considered as universal data types or updates to what HealthVault stores today.
Question/Answer pairs - the questions that are asked of the consumer, possible answers and the recorded answer or answers.
Risk profile - think of this as the results of analysis using the consumer information gathered in #1 and #2.

If your application would find utility in such a type, please reply to this post (preferred) or use the "contact me" link to send an email if you wish your feedback to be private. Please express your interest in working with us on this data type by Monday, March 17, 2008.
