Transfusion practice at Sørlandet Hospital

Norway has no overview of the number of patients who are transfused, their age and gender distribution or reasons for transfusion. We wished to investigate which patient groups received blood at Sørlandet Hospital in 2010-2011, and to test a method of electronic data linkage from treatment systems, with a view to further monitoring of blood consumption.

Data from all patients treated in somatic departments at Sørlandet Hospital in the period from 1 January 2010 to 31 December 2011 were linked to data from the blood bank with the aid of the system 'Forskning i sykehus'. SPSS version 23.0 was used for the statistical analyses.

A total of 19 108 red blood cells and platelet concentrates were transfused to 3 967 patients, with the same number of units for both genders. Patients older than 60 years accounted for 79 % of the total blood consumption. Patients in the main diagnostic group neoplasms had the most transfusion episodes, followed by the diagnostic groups injuries, diseases of the digestive system and diseases of the blood. In cases of primary and secondary hip prostheses, 33.8 % and 65.6 % of the patients received blood, respectively. For caesarean section the figure was 8.9 %.

Our data are comparable to data from other countries. The method is suitable for assessing and monitoring transfusion practice. It could also be used by other health trusts and to collect national data after all blood components and parameters such as haemoglobin, blood group and transfusion complications are included.
