Acute cardiac care & resuscitation
Association of socioeconomic status in the incidence, quality-of-care metrics, and outcomes for patients with cardiogenic shock in a pre-hospital setting
Authors' conclusion
This population-based study demonstrated discrepancies between SES status in the incidence, care metrics, and mortality rates of patients presenting to EMS with CS.
Study context
- Population
- Consecutive patients transported by emergency medical services (EMS) with cardiogenic shock, Victoria, Australia, 2015–2019
- Participants
- 2,628 patients
- Exposure
- Socioeconomic status (SES) quintiles
Main finding
As reported in the abstract
Age-standardized incidence of CS
P for trend < 0.001
- Overall age-standardized incidence, per 100 000 person-years
- 11.8 (95% CI 11.4-12.3)
Observational data: associations, not effects.
Further findings
Care metrics by SES
- Lower SES less likely to attend metropolitan hospitals, more likely received by inner regional and remote centres without revascularization
- Lower SES: greater proportion with cardiogenic shock (CS) due to non-ST elevation myocardial infarction (NSTEMI) or unstable angina pectoris (UAP); less likely to undergo coronary angiography
30-day all-cause mortality
- Increased in the lowest three SES quintiles vs highest quintile (multivariable analysis)
