HealthDay News – Among patients with cardiac arrest, teaching hospital status is associated with decreased in-hospital mortality, according to a study published in the September 1 issue of The American Journal of Cardiology.

Elena V. Dolmatova, MD, from the Rutgers New Jersey Medical School in Newark, and colleagues examined outcomes of patients with cardiac arrest in teaching vs non-teaching hospital settings using data from the Nationwide Inpatient Sample. Data were included for 731,107 cases of cardiac arrest: 47.6% were managed in teaching hospitals and 51.4% were managed in nonteaching hospitals.

Researchers found that cardiac arrest patients in teaching hospitals were younger, had fewer comorbidities, were less likely to be white, and were more likely to be uninsured. Mortality was significantly lower in teaching vs non-teaching hospitals (55.3% vs 58.8%; P<.001).

After adjustment for baseline patient and hospital characteristics, mortality remained significantly lower (odds ratio [OR]: 0.917; 95% confidence interval [CI]: 0.899-0.937). After adjustment for in-hospital procedures, the survival benefit was no longer observed (OR: 0.997; 95% CI: 0.974-1.02).

“In conclusion, teaching status of the hospital was associated with decreased in-hospital mortality in patients with cardiac arrest,” the authors wrote. “The differences in mortality disappeared after adjusting for in-hospital procedures, indicating that routine application of novel therapeutic methods in patients with cardiac arrest in teaching hospitals could translate into improved survival outcomes.”
