Introduction:

Blood transfusion is a replacement therapy for blood or one of its components, depending on the recipient's requirements.

Objective:

To describe the most consumed services for ten years.

Methods:

A descriptive, cross-sectional and retrospective observational study was carried out in Comandante Pinares Blood Bank at General Teaching Hospital from 2010 to 2020 through the documentary analysis method. The five services with the highest percentages of transfusions were chosen. The percentage calculation, the arithmetic mean and the standard deviation were used, as well as the Student's t test and a significance level of 5% (p< 0.05).

Results:

In 2010 and 2011, the highest percentage of transfusions were recorded at the internal medicine and surgery wards. From that year on, it was identified that oncohematology was the service that transfused the most, followed by surgery and internal medicine (with no differences between them), adult intensive care unit and orthopedics, correspondingly. The trend was to decrease the number of transfusions in all services.

Conclusions:

By being able to describe the services that consume most transfusions with a tendency to decrease over the years, it was possible to carry out other investigations in which the risk factors which influence the transfusion incidence were studied. Also it allows to include the reason for the reservation of blood in the variables for preparing those blood request schemes, as recommended by the World Health Organization, in addition to monitoring, evaluating and verifying compliance with the proposal.
