Yuh-Shan Ho, Ahmed Ben Salem, Mahdi Kchaou and 3 others
PMID 41887615WHAT IT FOUND
A mapping of 1150 papers using the MIMIC-IV database shows research focuses on mortality, sepsis and machine learning.
The authors note a gap in studies about nursing workflows and patient experience, suggesting future work should target these areas.
Key findings
01The review analysed 1150 publications from 2021 to 2024 that used the MIMIC-IV database.
02Dominant research themes identified were mortality prediction, sepsis, acute kidney injury, intensive care workflows and machine learning.
03The authors identify a gap in research concerning nursing-sensitive outcomes, patient experience and ICU workflows, calling for more nurse-led studies in these areas.

What it does not show
This is a review of other studies, not a direct study of patients or treatments. The authors note that using only the Web of Science database may have missed relevant nursing-specific studies indexed in other databases like PubMed. The analysis relies on keywords and titles, which may not accurately capture the full depth or clinical nuance of each paper.
Declared interests
The authors declare no conflicts of interest and report no funding.
The easy way to misread this
Do not interpret this paper as evidence that MIMIC-IV models are ready for bedside nursing practice or that they have been validated for nursing-sensitive outcomes. The review itself states that research in these specific areas is underdeveloped and that most existing work focuses on physiological prediction rather than care processes.
