ABSTRACT

BACKGROUND: Patients hospitalized with acute heart disease [acute myocardial infarction (MI); heart disease exacerbation] may require red blood cell (RBC) transfusion. These patients are at increased risk for morbidity and mortality. Hematological biomarkers may help to identify increased mortality risk. The aim of the study was to evaluate the association between hematological biomarkers and survival in these patients. METHODS: A historical cohort study of all patients admitted to an internal medicine department, who were diagnosed with acute heart disease and requiring RBC transfusion, was carried out in a tertiary medical center between 2009-2014. The association between hematological biomarkers and 30-, 90-day and 5-year mortality was studied. RESULTS: A total of 254 patients (median age 80 years, IQR 74-86.25; 40.9% females; acute MI 24.8%), were included. During the 5-year follow-up 212(83.5%) patients died. In a multivariate analysis the lower platelet to neutrophil ratio (PNR) was significantly associated with increased 30-, 90-day and 5-year mortality (p<0.001, 0.041, 0.003 respectively). A higher red cell distribution width (RDW) was significantly associated with 30- and 90-day mortality (p=0.003, 0.023 respectively), while higher neutrophil to lymphocyte ratio (NLR) was associated with increased 30-day and 5-year mortality (p= 0.036, 0.033 respectively). CONCLUSIONS: Hematological biomarkers may help to identify increased mortality risk of acute heart disease patients, receiving RBC transfusions in an internal medicine department.

ABSTRACT

BACKGROUND: Transfusion guidelines advocate restrictive rather than liberal use of red blood cells (RBC) and are based mostly on randomized trials in intensive care and surgical departments. We aimed to study RBC transfusion practice in the medical patients' population. METHODS: The data in this study were collected from patients over the age of 18 years admitted to an Internal Medicine department between 2009 and 2014 who received at least one unit of packed red blood cells (RBC). In addition, data on demographics, patients' diagnoses, laboratory tests and number of transfused RBC units were extracted from the electronic health records. RESULTS: One thousand three hundred and twenty eight patients were included, having mean age of 75 ± 14 years. The median hemoglobin (Hb) trigger for RBC transfusion was 8.0 g/dl (IQR 7.3-8.7g/dl), and most patients received either one (43.4%) or two (33.4%) RBC units. There was no significant difference in Hb trigger between males and females (Hb 8.0 g/dl and 7.9 g/dl, respectively, p = 0.098), and a weak correlation with age (r = 0.108 p = 0.001). Patients with cardiovascular and lung diseases had a statistically significant higher Hb trigger compared to patients without those diagnoses, however the median difference between them was 0.5 g/dl or less. CONCLUSIONS: These "real world" data we collected show a Hb trigger compliant with the upper limit of published guidelines and influenced by medical patients' common diagnoses. Prospective trials addressing patients hospitalized in internal medicine departments could further contribute to transfusion decision algorithms.

ABSTRACT

Patients hospitalized with pneumonia may require packed red blood cell (RBC) transfusion during their hospital stay. Patient survival may be associated with the transfusion trigger. These patients may need a higher hemoglobin (Hb) trigger than that suggested by the AABB guidelines (7 g/dL).The objective of this study was to evaluate the association between the initial transfusion Hb trigger and in-hospital mortality.A historical cohort study of all patients hospitalized in an internal medicine ward between 2009 and 2014 with pneumonia, who received at least 1 unit of RBC, was evaluated. The primary outcome was all-cause in-hospital mortality.One hundred males and 77 females with a median age of 80 (interquartile range 71-87) years were included. The median Hb trigger was 8.10 g/dL. Mortality rate was 56% in patients with Hb trigger ≤7 g/dL, 43.8% in Hb trigger 7 to 8 g/dL, and 29.5% in Hb trigger >8 g/dL (P = .045). Patients in the 3 Hb trigger categories did not differ in age, sex, comorbidities, albumin, creatinine, C-reactive protein, white blood cells, and platelet counts. The result of a multivariate analysis showed that only lower Hb trigger (odds ratio [OR]≤ 7vs.>8 = 5.24, OR7-8vs.>8 = 2.13, P = .035) and higher neutrophil count (P = .012) were associated with increased in-hospital mortality.In conclusion, a lower transfusion trigger is associated with increased risk for in-hospital mortality in patients hospitalized with pneumonia requiring RBC transfusion.
