Clinical and economic outcomes associated with hospitalizations for acute idiopathic pericarditis in the United States.

Abstract Background Outcomes-based data regarding the management of hospitalized U.S. patients with acute idiopathic pericarditis (AIP) are lacking. Objectives This study sought to elucidate the clinical and economic outcomes associated with the inpatient care of AIP. Methods Cohort study of adults with AIP; multivariable analyses of clinical and economic outcomes (inpatient mortality, surgical or medical complications, length of stay, and medical charges). Results Surgical or medical complications, pericardiocentesis, and pericardiotomy were each independently associated with a significantly higher odds of inpatient mortality (p Conclusions U.S. inpatient cases of AIP are associated with significant use of healthcare resources, disparities, morbidity, and mortality.
