Transfusion practice is reported to differ considerably between countries. Comparisons often rely on transfusion rates, incidence ‐ or prevalence rates. In this paper, the one‐year period prevalence rate (1‐YPPR) of transfusion of red cells (RBC) is presented. Transfusion data, demographic data and patient data were retrospectively combined to calculate sex and diagnosis specific and age standardized 1‐YPPR s of RBC transfusion for the complete population in a Danish county. During the calendar year of 2006, 4427 patients received RBC transfusion in Funen County. The crude 1‐YPPR of RBC transfusion was 9.2/1000 citizens. Most of the transfused patients had a main diagnosis of neoplasm (22% of recipients), diseases of the circulatory system (15%), the digestive system (15%), injuries (13%) and diseases of the blood (8%). Age standardization reversed the relation between sex specific 1‐YPPRs, yielding a statistically significantly higher 1‐YPPR in males (6.8/1000) vs. females (6.3/1000). The method for calculating a diagnosis specific 1‐YPPR of transfusion of RBC is presented and proposed as an option for comparison of transfusion practice with other transfusion centres. The crude and the diagnosis specific 1‐YPPR s are found to increase with age. Thus, age standardization of crude prevalence rates is necessary for meaningful comparisons between populations.
