Thrombocytopenia versus SOFA to predict mortality in patients with sepsis in the Intensive Care Unit of a tertiary hospital in Guatemala
Journal Title: Revista Científica Facultad de Ciencias Químicas y Farmacia - Year 2019, Vol 29, Issue 1
Abstract
The most common coagulation disorder in the intensive care unit is thrombocytopenia. Considering the fundamental role of platelets in hemostasis and as markers of disseminated intravascular coagulation, a significant decrease in platelet count is alarming in the context of septic patients, and it is known to be a predictor of death. The objective was to compare the ability of the platelet count with the Sequential Organ Failure Assessment (SOFA) to predict death in patients with severe sepsis or septic shock. A longitudinal study was conducted with a sample of 29 consecutive cases evaluated during January to December 2015 in the Intensive Care Unit of the General Hospital of Diseases (HGE) of the Guatemalan Social Security Institute. Platelet and SOFA counts were performed at the first and the fifth day of hospitalization, documenting the outcome of the patients. Of the total, 51.7% of the patients were men and 48.3% were women, with an average age of 62.0 (16.9) years, median SOFA on admission of 10 units (Q1=4, Q3=14), and platelet median on admission of 196000 (Q1=100000, Q3=250000). The univariate association between thrombocytopenia and death was significant (p = .021, RR = 2.45, CI 95% [1.21, 4.99]). According to a Bootstrap test, there is no significant difference between the predictive capacity of SOFA and platelet count (p = .965). It was concluded that the presence of thrombocytopenia is a simple predictor of death in patients with severe sepsis or septic shock, with similar capacity to SOFA
