Data Element Information
Use Case Description(s)
Use Case Description This data element is used in electronic case reporting (eCR) which provides case reports to state, tribal, local, or territorial (STLT) public health agencies (PHA) for reportable diseases and conditions. Submission of reports of persons with these conditions is required by law in every US State and Territory. Public health epidemiologists have identified the data elements necessary to be included in electronic case reports from healthcare organizations and providers. The transition is underway from providing these reports via fax, mail, email, or phone to using data available in the electronic health records to submit reports electronically to all PHAs. Once received at the PHA, this data is use for surveillance, case management and public health response efforts such as contact tracing or other mitigation efforts.

Specific to this data element: used to assess appropriate treatment and follow-up, appropriate for scoring/risk ascertainment.
Estimate the breadth of applicability of the use case(s) for this data element This data is exchanged as part of the extensive implementation of electronic case reporting (eCR) in the US; eCR is in broad implementation nationwide with thousands of reporting health care organizations.

ASTP Evaluation Details
Each submitted Data Element has been evaluated based on the following criteria. The overall Level classification is a composite of the maturity based on these individual criteria. This information can be used to identify areas that require additional work to raise the overall classification level and consideration for inclusion in future versions of USCDI
Criterion #1
Maturity - Current Standards		 Level 2 - Data element is represented by a terminology standard or SDO-balloted technical specification or implementation guide.
Criterion #2
Maturity - Current Use 		Level 2 - Data element is captured, stored, or accessed in multiple production EHRs or other HIT modules from more than one developer.
Criterion #3
Maturity - Current Exchange		 Level 2 - Data element is electronically exchanged between more than two production EHRs or other HIT modules of different developers using available interoperability standards.
Criterion #4
Use Case(s) - Breadth of Applicability		 Level 0 - Use cases apply to a limited number of care settings or specialties, or data element represents a specialization of other, more general data elements.
Evaluation Comment This data element represents a narrow use case already captured as Encounter Diagnosis metadata.

1. Optional: Background Text / Cover Letter

The "Optional Background Text / Cover Letter" field provides space for additional context or introductory information related to your comment.

If you wish to provide context, explanation, or an introduction to your comment, enter this information in the field labeled "Optional Background Text / Cover Letter." This is entirely optional and is most useful when submitting multiple related comments or when additional background would help reviewers understand your feedback.

If you are only commenting on a single data class or element, you may leave this field blank.

2. Select the Data Class

To specify which data class your comment addresses:

  1. In the "Data Class" drop-down menu, select the appropriate data class you want to comment on.
  2. If you are providing a general comment that is not specific to a data element, select "General" from the options. Comments with this designation will be displayed on the USCDI landing page.
  3. Note that the Data Class field will automatically populate based on your current location in the platform:
    1. If you are on a data class page, the field will be set to that specific data class
    2. If you are on a data element page, the corresponding data class will be pre-selected
       

3. Select the Data Element

To specify which data element your comment addresses:

  1. In the "Data Element" drop-down menu, select the specific data element you want to comment on.
  2. The drop-down menu will display only the elements available under the data class you selected in the previous step.
  3. You can use the search function within the drop-down to quickly locate a specific data element.
  4. If you are commenting on the data class itself rather than a specific element, you may leave this field blank.

Note: Comments on a specific data element will appear on the respective data element page, while comments on a data class (without a specific element selected) will appear on the landing page for that data class.
 

Data Class and Data Element

Fig 1 The "Data Class" and "Data Element" dropdown menus allow users to specify the exact content they wish to comment on.

4. Optional: Propose New Data Class or Element

If you cannot find the appropriate data class or element for your comment:

  1. Instead of clicking the "Comment On An Existing Data Class Or Element" button, click the adjacent button labeled "Propose a New Data Class or Data Element."
  2. This will redirect you to the ONDEC (ONC New Data Element and Class) Submission System.
  3. In the ONDEC system, follow the provided instructions to submit your proposal for a new data class or element.
  4. Once your proposal is submitted through ONDEC, it will be reviewed separately from the commenting process.
Propose New Data Class or Element

5. Complete the Comment Form

Fill out the required fields in the comment form:

Subject: Enter a brief, descriptive title that summarizes your comment. This helps reviewers quickly understand the nature of your feedback.

Comment: In this field, provide the full details of your comment or feedback. Be as clear and specific as possible about your suggestions, concerns, or observations. Include any relevant details that support your position.

6. Optional: Add Additional Comments

If you need to comment on multiple data classes or elements:

  1. After completing your first comment, click the link labeled "Comment on another data element" at the bottom of the form.
  2. A new comment section will appear, allowing you to enter details for your additional comment.
  3. For each additional comment, you must select the appropriate data class and data element from the drop-down menus.
  4. Complete the Subject and Comment fields for your additional comment.
  5. Repeat this process for each additional comment you wish to submit.
