Meaning of note_seq in MIMIC-IV Notes Discharge #1679

Closed prabaey closed 7 months ago

Prerequisites

Description

According to the documentation, note_seq in the MIMIC-IV Notes Discharge table has the following meaning: "A monotonically increasing integer which chronologically sorts the notes within note_type categories. That is, notes can be ordered sequentially by note_seq."

Why do we need this attribute? Is it not possible to chronologically sort notes according to the chartdate? Does note_seq indicate within-patient ordering, or general ordering? I feel like I'm missing something. Thanks for the clarification!

I don't think you are missing anything. Sometimes there is redundancy in information, and sometimes fields such as these make it easier for us to build and maintain the dataset.
