Description

Hi MIMIC team:

I have recently been trying to analyse the MIMIC III data and I am focusing on the medication prescriptions and discharge summaries. However, I have found some questions that I would like to ask:

The first problem is that many of the discharge summaries do not correspond to the drug prescriptions by subject_id and hadm_id, amounting to 6402 (about 10.73% of all discharge summaries).

Another problem is that some of the discharge summaries, although they do correspond to drug prescriptions, have many omissions. By this I mean that the drugs mentioned in the discharge summaries do not appear in the prescriptions data. subject_id = 14291, hadm_id = 139852 is an example of this. Only one of the nine drugs mentioned in the MEDICATIONS section of the discharge summary appears in the PRESCRIPTIONS table. POST DISCHARGE MEDICATIONS has 5 drugs in the PRESCRIPTIONS section, but there are still drugs such as Augmentin and donepezile that are missing.

I would like to ask why this is the case. Why is there a mismatch between the drug prescriptions and the discharge notes?

Thank you for all your work

The issue names MIMIC III discharge summaries and the PRESCRIPTIONS table, but no repository files, tests, or entry points. Start by checking the linked MIMIC documentation and comparing records by subject_id and hadm_id, including the provided example. Done means documenting the reason for unmatched or omitted medications; no code change is specified.
