Description

Hello MIMIC / PhysioNet team,

When querying the BigQuery dataset, we found that physionet-data.mimiciv_2_2_derived contains only 49 tables (excluding _version), which appears incomplete compared with the expected derived schema.

SELECT table_name
FROM `physionet-data.mimiciv_2_2_derived.INFORMATION_SCHEMA.TABLES`
ORDER BY table_name;

This query returns 49 tables only. However, the expected derived release contains 65 tables (excluding _metadata, e.g. physionet-data.mimiciv_3_1_derived), with missing tables including:
oxygen_delivery, phenylephrine, rhythm, rrt, sapsii, sepsis3, sirs, sofa, suspicion_of_infection, urine_output, urine_output_rate, vasoactive_agent, vasopressin, ventilation, ventilator_setting, vitalsign, weight_durations.

Please clarify whether the BigQuery derived dataset is intentionally partial or will be completed.

Thank you very much for your support.

Best regards

Research direction

Start with the INFORMATION_SCHEMA.TABLES query against physionet-data.mimiciv_2_2_derived and compare its results with the expected 65-table derived schema, including the listed missing tables. Done means establishing whether the BigQuery dataset is intentionally partial or identifying what is needed for it to match the expected release.
