Brief Summary:
To develop and apply quantitative methods by which to measure and characterize blood transfusion practice in specific diagnoses and procedures to open scientific communication about transfusion practice within and across institutions and to develop simpler methods for estimating annual national blood collections and transfusions
Detailed Description:
DESIGN NARRATIVE
The study was a subproject within a Specialized Centers of Research SCOR in Transfusion Medicine The experimental design was based on the study and analysis of several unique sets of data One set consisted of abstracted patient data including ICD-9-CM diagnosis and procedure DRG and red cell units transfused from a constant set 100 of United States hospitals for the years 1980828486 to which a new set of data was added for the year 1989 A similar set of data were gathered from eight cooperating teaching hospitals over the first four years of the grant term this set included data for transfusions of all blood components autologous units and factor preparations A third data base contained the data for four United States surveys conducted in 1982848687 and was expanded to include 1990 and 92 Using these data four main tasks were addressed A Pan-DRG red cell transfusion study was conducted to ascertain red cell use across all DRGs and ICD-9-CM codes Extensive efforts were devoted to developing new methods to characterize transfusion practice A series of studies were devoted to characterizing transfusions of all blood components in a selected number of ICD-9-CM classes The purpose of the fourth task was to develop simpler and more rapid alternative methods for producing national estimates of transfusion activity as part of this tasknew surveys were conducted for 1990 and 92
Among the questions studied were Was it possible to identify distinctive attributes of the patients who though operated did not require a transfusion or who required a large volume of blood Were transfusions of non-red cell components related to use of red cells Could transfusion frequency diagnosis for all blood products be used as a measure of transfusion practice Did longitudinal comparisons of transfusions over the 9-year interval 1980-1989 reveal significant trends Was it possible to discriminate quantitatively between transfusion practices in different hospitals or set of hospitals or at different times What was the effect of autologous blood programs in transfusion practice What was the contribution of comorbid conditions on red cell and component transfusion patterns
The dollars for the subproject were approximately 25 percent of total dollars spent each year for the Center
The study completion date listed in this record was obtained from the End Date entered in the Protocol Registration and Results System PRS record
