Newborn Chart Events

There are 60,877 subjects with an anchor age of 0 and admitting service listed as NB (Newborn) or NBB (Newborn Baby). For example:

subject_id | hadm_id | anchor_age | curr_service
10000019 | 25058216 | 0 | NB
10000044 | 28970421 | 0 | NB
10000074 | 29020699 | 0 | NB
10000200 | 24930234 | 0 | NB
10000306 | 22750800 | 0 | NB
10000674 | 22345063 | 0 | NB
10000730 | 24554295 | 0 | NB
10000730 | 24810836 | 0 | NBB
10000771 | 26153462 | 0 | NB
10000816 | 29954613 | 0 | NB

None of these subjects (or their associated HADM_IDs) have any corresponding data in the ICU_CHARTEVENTS table. They do, however, for example, have corresponding data in the DIAGNOSES_ICD table.

Is this data captured elsewhere in the MIMIC-IV database or planned for later release? Is it possible to gain access to this data?

I specifically would like to work with data associated with these newborn admissions, so I would like to gain access to birth weights if at all possible. In the MIMIC-III release, birth weights were part of the CHARTEVENTS table.

Any insight would be greatly appreciated.

Start by comparing the listed newborn admissions in ICU_CHARTEVENTS and DIAGNOSES_ICD, then review the MIMIC-IV release information alongside the earlier MIMIC-III CHARTEVENTS reference. Done means establishing whether newborn chart events or birth weights exist elsewhere, are planned for release, or require separate access.
