Diagnosis: Anaphylactic Reaction to Common Baker's Yeast Value Set Description from VSAC Clinical Focus: This value set contains concepts that represent a history of an anaphylactic (extreme allergy) reaction to baker's yeast. Data Element Scope: This value set may use the Quality Data Model (QDM) category related to Diagnosis. Inclusion Criteria: Includes only relevant concepts associated with an anaphylactic reaction to baker's yeast. Exclusion Criteria: No exclusions. Constrained to codes in the Diagnosis: Anaphylactic Reaction to Common Baker's Yeast value set (2.16.840.1.113883.3.464.1003.199.12.1032) QDM Datatype and Definition (QDM Version 5.3) Diagnosis Data elements that meet criteria using this datatype should document the Condition/Diagnosis/Problem and its corresponding value set. The onset dateTime corresponds to the implicit start dateTime of the datatype and the abatement dateTime corresponds to the implicit stop dateTime of the datatype. If the abatement dateTime is not present, then the diagnosis is considered to still be active. When this datatype is used with timing relationships, the criterion is looking for an active diagnosis for the time frame indicated by the timing relationships. Timing: The Prevalence Period references the time from the onset date to the abatement date.
