Background and Aims:

Proximal femoral fracture has become an increasingly severe disease with reported mortality ranging from 8.4-36%. Prior studies pointed out various risk factors, such as advancing age, comorbidities and prefracture functional disability. Recently, several studies reported close associations between anemia and long-term mortality. The aim of this study was to determine the relationship between admission hemoglobin level and one-year mortality.

Methods:

Prospective, observational, clinical study, carried out from 1st July 2012 to 30th June 2013 in Gaia/Espinho Hospital Centre. The study included all patients who were admitted to the Emergency Department with proximal femoral fracture. For the purposes of this report, we excluded 8 patients for whom we lacked data on hemoglobin values. We extracted information on all admission hemoglobin measurements from Medical System Support. Women with admission hemoglobin levels below 12.0 grams per deciliter and men with admission hemoglobin levels below 13.0 grams per deciliter were classified as anemic. Statistical analysis was performed using the SPSS V.21.0. The chi-square test and the Student's t test for independent samples (significance level 0.05) were performed to examine the association between hemoglobin level on admission and 1-year mortality. 

Results:

The average hemoglobin on admission was 12.5 ± 5.8 g/dL. Anemia was present in 45.5% of patients. One-year mortality rate (28.8% vs. 16.5%; p=0.032) was significantly higher for patients anemic on admission.

Conclusions:

We observed anemia on admission in 45.5% of patients, which was similar to that reported in other studies. One-year mortality rate was significantly higher for patients who were anemic on admission.
