(HealthDay News) – Despite differences in processes of care and raw mortality for patients with severe sepsis and septic shock in the United States and Europe, after adjustment, mortality rates are similar, according to a study published online Oct 26 in The Lancet Infectious Diseases.
Mitchell M Levy, MD, from the Warren Alpert Medical School of Brown University in Providence, RI, and colleagues compared models of care and outcomes for 25,375 patients with severe sepsis and septic shock, entered into the Surviving Sepsis Campaign database from Europe (79 hospital sites with 6,609 patients) and the United States (107 units with 18,766 patients).
The researchers found that, in the United States, 65.1% of patients were admitted to the intensive care unit (ICU) from emergency departments, while in Europe, 51.5% of patients were admitted from hospital wards. In Europe, the median stay on the hospital wards before ICU admission was longer than in the United States (1 day vs. 0.1 days). In Europe, there was a longer median length of stay in the ICU (7.8 days vs. 4.2 days) and the hospital (22.8 days vs. 10.5 days). Raw hospital mortality was increased in Europe versus the United States (41.1% vs. 28.3%), but adjusted mortality was not significantly different (32.3% and 31.3%, respectively; P=0.468). The United States exhibited higher complete compliance with all applicable elements of the sepsis resuscitation bundle (21.6% vs. 18.4%).
“The significant difference in unadjusted mortality and the fact that this difference disappears with severity adjustment raise important questions about the effect of the approach to critical care in Europe compared with that in the U.S.A.,” the authors write.
Two authors disclosed financial ties to pharmaceutical and medical equipment companies, including Eli Lilly and Philips Medical Systems, both of which partially funded the study.
