Geographic Access to Care and Mortality in Cardiogenic Shock: A Nationwide Cohort Analysis
Authors' conclusion
Longer hospital arrival times are significantly associated with increased in-hospital and long-term mortality in patients with CS.
Study context
- Population
- Adults (≥ 18 yr) admitted to an ICU with cardiogenic shock, South Korean tertiary hospitals, 2017–2022
- Participants
- 80,263 adults
- Exposure
- Estimated hospital arrival time 10-30, 30-60 and > 60 min vs < 10 min
- Outcome
- All-cause mortality, including in-hospital and post-discharge mortality
Methodological detailsmultivariable logistic and Cox regression
- Multivariable logistic and Cox regression
