CosdV8ConditionOccurrencePrimaryDiagnosis

Assumptions

• Any changes in a Diagnosis that may occur in later submissions, for the same Diagnosis date, is taken to be an additional diagnosis as opposed to a change (hence removal of the original)
• If the same Diagnosis occurs but we have 2 separate “basis of diagnosis” values, then the first one will be taken only

Assumptions

• For a given Diagnosis date, all valid combinations of Histology and Topography are added (thereby giving us an ICD-O-3 condition) as well as the ICD10 Diagnosis.
• Any changes in a Diagnosis that may occur in later submissions, for the same Diagnosis date, is taken to be an additional diagnosis as opposed to a change (hence removal of the original)

Duplicates

CDS data contains numerous duplicated records for cds_diagnosis.DiagnosisCode (condition_concept_id), cds_line01.cdsActivityDate (condition_start_date) and cds_line01.NHSNumber (person_id).

In order to avoid true duplicates occurring in the data, we have included distinct records for cds_diagnosis.DiagnosisCode (condition_concept_id), cds_line01.cdsActivityDate (condition_start_date) , cds_line01.NHSNumber (person_id) and cds_line01.RecordConnectionIdentifier and excluded all duplicates.
