Association between intensive care unit nursing grade and mortality in patients with cardiogenic shock and its cost-effectiveness
Authors' conclusion
For patients with CS, ICU grade 1 with a high-intensity nursing staff was associated with reduced mortality and more cost-effectiveness during hospitalization compared to grade 2 and grade ≥ 3, and its beneficial effects were more pronounced in subjects at high risk of CS.

In-hospital mortality (subgroups)
- Benefit of high-intensity nursing grade more prominent in patients who received CPR or multiple vasopressors
