Brief summary

This table contains data on diagnoses for patients for each of their hospital stays. Each row represents a unique diagnosis for a patient during a hospital stay, and the columns provide information about the diagnosis, including the International Classification of Diseases code (ICD) code on their version 10, the type of diagnosis (primary or secondary), and the date on which the diagnosis was registered. The table also includes identifiers for the patient and the hospital stay. The table diag_events_dic can be consulted for a description about the ICD codes. The "Type of diagnosis" column (diag_type) in the p_zero.diag_events table indicates whether the diagnosis is historical (H), representing diagnoses made before admission to the ward, or current (C), signifying diagnoses made during the specific ward stay.
