encounter_augmented
Primary Key: encounter_id
Each record in this table represents a unique acute inpatient admission. However, the main difference between this table and readmission_summary is that this table contains every acute inpatient encounter found in core.encounter whereas readmission_summary filters out acute inpatient encounters that have data quality problems which prevent them from being included in readmission analytics. A table detailing all encounters with extra information related to the encounter, and flags for information that might affect the readmission calculations.
This table includes columns for data quality tests related to readmissions, so you can see why admissions that are not in readmission_summary were excluded.
