PMID 39821220WHAT IT FOUND
ICU ward and nursing quality scores were higher with 9S plus hierarchical management, comfort was higher and disease severity scores were lower, but adverse events were not clearly different.
Key findings
01The combined management group had higher ward management quality scores than the control group after one month.
02The combined management group also had higher nursing quality and comfort scores and lower APACHE II scores than the control group after one month.
03Adverse events were not significantly different between groups.

What it does not show
The study is retrospective and does not describe randomisation or blinding. The paper does not state which outcome was primary. Only 90 patients from one hospital were studied, and management lasted one month. Ward management and nursing quality were assessed with hospital self-developed scales. The intervention combined many 9S components with hierarchical management, so the effect of any single component cannot be separated. The adverse-event difference was not significant.
The easy way to misread this
Do not conclude that this management model reduces adverse ICU events. The adverse-event difference was not significant, and the study was retrospective without randomisation.
