Impact of a Cardiogenic Shock Program on Mortality in a Non-Transplant Hospital.

ABSTRACT

INTRODUCTION: Cardiogenic shock is associated with high in-hospital morbidity and mortality. Improvements in this care process could lead to better outcomes. METHODS: This retrospective study of patients with cardiogenic shock compared two periods no specific program to address cardiogenic shock and implementation of a cardiogenic shock program. This program included the establishment of a multidisciplinary team (shock team), early alert to the transplant hospital, initiation of a ventricular assist extracorporeal membrane oxygenation (ECMO) program, and extension of continuous care by acute cardiovascular care specialists. The primary objective was to analyse whether there were differences between in-hospital mortality and mortality during follow-up. Predictors of in-hospital mortality were examined as a secondary objective. RESULTS: A total of 139 patients were enrolled 69 of them in the previous period and 70 in the cardiogenic shock program period. There was a significant reduction in in-hospital mortality (55.1% vs 37.1%; p=0.03) and mortality during follow-up (62.7% vs 44.6%; p=0.03) in the second period. Diabetes mellitus, ejection fraction, out-of-hospital cardiac arrest, and implementation of the cardiogenic shock program were independent predictors of in-hospital mortality. CONCLUSIONS: The implementation of a comprehensive cardiogenic shock program in a non-transplanting hospital improved in-hospital and follow-up mortality of patients in cardiogenic shock.
