Data Element Information
Use Case Description(s)
Use Case Description Documenting and exchanging the Date of Onset and Date of Diagnosis for diagnoses listed in the past medical history and active problem list would support the ability of public health and researchers to calculate incidence and prevalence statistics for reportable and other health conditions. For practicing clinicians and patients documenting this data will provide a more robust picture and understanding of both individual and related conditions and support a deeper understanding of the evolution of a patient's condition and overall health status over time. For those managing the health of populations knowing how long a patient has had a condition could help identify those at the greatest need for outreach/engagement and allowing resources to be directed to where they might provide the greatest value.
Estimate the breadth of applicability of the use case(s) for this data element Potentially all clinicians
Healthcare Aims
  • Improving patient experience of care (quality and/or satisfaction)
  • Improving the health of populations
  • Improving provider experience of care

Estimate of Overall Burden EHRs and other HIT systems likely all capture, at least in audit trail/metadata, the date that a diagnosis was entered into the active problem list and/or medical history list. This is quite different in meaning than the Date of Onset so an additional date field would need to be added, the data stored in the database, data added to interoperability payloads for send, receive, ingestion, etc..
Other Implementation Challenges There would be a need to develop and maintain a clear definition of how this field is to be populated as well as a determination of what types of actors should be allowed to populate or update this data field. Would also need to define how to capture and maintain a provenance history for this data element that could eventually travel with the data as it is transmitted between HIT systems. It would be appropriate for this field to accept fuzzy dates as the date of onset for a given condition may sometimes only be available as an estimate such as a year or month.

CDC's Consolidated Comment

CSTE Comment:

  • CSTE strongly encourages the inclusion of date of onset in USCDI v3. This is one of the most important data elements for public health. Date of onset often is the defining date for the beginning of a reportable condition and is used to classify cases and detect outbreaks and clusters. Exposures must be investigated in relation to the onset date. If the onset date is not captured as a distinct structural data point, public health staff must dig for it in notes or other parts of the medical record and it is inevitably vague and sometimes missing. Date of diagnosis is not the same as date of onset. Date of onset is defined as the first clinical symptom or sign for a particular condition. It would be highly beneficial if date of onset could be captured for each problem/diagnosis or condition noted in the medical record but if this is not possible it should at a minimum be noted for the primary diagnosis of the patient encounter.

Unified Comment from CDC

  • General Comment: Date of Onset currently does not  have a definition.
     
  • Proposed Definition: The estimated date, actual date or date-time the condition began.
     
  • Additional Use Cases:The Making EHR Data More Available for Research and Public Health (MedMorph) project's goal is to create a reliable, scalable, and interoperable method to get electronic health record data for multiple public health and research scenarios (use cases). MedMorph has identified Central Cancer Registry Reporting, Healthcare Surveys,  Hepatitis C Reporting, electronic Initial Case Reporting (eICR), Multiple Chronic Conditions (MCC) eCare Plan, Message Mapping Guide (MMG) for COVID 19, PCORnet, Birth and Birth Defect Reporting use cases that support the adoption of this data elements.

Unified Comment from CDC

  • CDC considers this element to be high priority and strongly recommends its inclusion in the USCDI V3.
     
  • CSTE supports inclusion of this measure into USCDI v3: Date of onset for conditions is extremely important and we are very supportive of this element being included in USCDI.
  1. Ensure date of onset is NOT the same as date of diagnosis – date of onset is considered date of first clinical sign or symptom
  2. Frequently date of onset would be captured in clinical notes field (unstructured data) so this would be beneficial to PH for a date of onset to be captured per condition.

Suggest changing the definition

MedMorph supports the addition of the Date of Onset element, but suggests a slight change to the definition. The word "capture" can be easily confused with the recorded date. Also, using "diagnosis" in the definition is more specific than intended. At this point in care, it is simply the onset of the condition or problem.


Suggested Definition: The estimated date, actual date or date-time the condition began.

MedMorph's support of Date of Onset

The MedMorph Project supports the addition of Date of Onset, but requests slight tweaking of the definition to cover the broader class of Problems (instead of just for diagnoses as the existing definition suggests). The existing proposed definition also includes extraneous information that should not be included in the definition.

Suggested definition:
A date field associated with each item on a patient's problem list and medical history to capture the date on which the signs/symptoms/pathology of the problem began.

This field is for general comments on this specific data element. To submit new USCDI data classes and/or data elements, please use the USCDI ONDEC system: https://healthit.gov/ONDEC

I fully support the date of diagnosis as a useful addition.
