Output field list:
 Field  Description
condition_concept_id A foreign key that refers to a standard condition concept identifier in the vocabulary.
concept_name An unambiguous, meaningful and descriptive name for the concept.
condition_era_start_date The start date for the condition era constructed from the individual instances of condition occurrences. It is the start date of the very first chronologically recorded instance of the condition.
person_id A foreign key identifier to the person who is experiencing the condition during the condition era. The demographic details of that person are stored in the person table.
death_date The date the person deceased. If the precise date including day or month is not known or not allowed, December is used as the default month, and the last day of the month the default day.
