The purpose of this study was to analyze blood utilization by 92,815 transfused patients treated in 300 United States hospitals during 1974. In order to achieve this end, transfused patients were first divided into 349 diagnosis groups. Blood transfusion data for the highest ranking 50 groups in terms of total units administered to patients in the group are presented and discussed, as well as the blood needs of patients in 19 major disease categories such as malignant neoplasm. Blood transfusion is then correlated with the month of the year by presenting the mean number and the total number of units transfused per month for the country as a whole and for each of four geographic regions. Individual diagnosis groups with significant variation in the mean number of units transfused among the months are also listed and discussed. To aid in the interpretation of mean monthly transfusion rates for the various diagnosis groups, a list of operative procedures with significant variation in the quarterly frequency is offered. Diagnosis groups with significant variation in the mean transfusion rate among the four geographic regions are presented with interpretation of the data.
