Use of platelet concentrate in eastern Ontario

Area of Science:

• Hematology
• Transfusion Medicine

Background:

• Platelet concentrate transfusions are increasingly used in Canada.
• Understanding current transfusion practices and their efficacy is crucial.

Purpose of the Study:

• To analyze the utilization patterns of platelet concentrate transfusions.
• To assess the effectiveness of platelet transfusions in different clinical settings.

Main Methods:

• A 4-month observational study was conducted in six eastern Ontario hospitals in 1985.
• Data on 4801 units transfused to 303 patients were collected and analyzed.

Main Results:

• Cardiovascular services accounted for the largest proportion of platelet concentrate use (28%), primarily for aortocoronary bypass grafting.
• A significant increase in platelet count post-transfusion was observed in 75% of cases, with an average increment of 3.4 x 10(9)/L per unit.
• Prophylactic use in cardiovascular procedures is being questioned, contrasting with established use in chemotherapy-induced thrombocytopenia.

Conclusions:

• Continued surveillance of platelet concentrate use is advised.
• Re-evaluation of the objectives for platelet transfusion therapy is necessary to ensure appropriate application.
