Data for the Smoking Cessation Entity should be selected and submitted using a transactional changes method. Records should be sent on the submission criteria described in the Reference entities (ADDS and UPDATES are to be sent in the .csv files, and DELETES are sent in the optional .del files).
The fields patient_chart_number, submitting_hospital_number, registration_date, and disease_sequence_number are used to establish the uniqueness of a Smoking Cessation record.
Records that match on all of these fields are considered to represent the same Smoking Cessation record. The latest record will overwrite all previous records.
Records that differ on any or all of these fields are considered to be a new record, and will not overwrite a previously submitted record.
If the same record (ie. matches on the four fields above) appears more than once in the same file and there are differences between them, the last record in the file will overwrite the previous one(s).
