Record

Comorbidity CR  PR    episode   

This record contains details for comorbidities that held during the reference periods specified in Comorbidities period.

The start date of the episode must be the date of the diagnosis of the comorbidity specified in Comorbidity code, if known. The stop date of the episode must be the end of the symptoms of the comorbidity.

Note that the start and stop dates of comorbidity episodes may extend over multiple reference periods. For example, a comorbidity that held during the 12 months before the baseline entry may have been diagnosed many years earlier. Furthermore, a comorbidity that was entered at baseline may still hold at follow up; in this case, the Ongoing date of the episode already entered should be updated to the date of the follow up.

Comorbidity code CR  PR 

Comorbidity as code of the classification specified in Comorbidity classification. Registries, in particular patient-reported registries, may provide common comorbidities as a list in their data collection forms or have users enter the diagnosis in a free-text field which is then coded by a curator.
