[Maximum surgical blood ordering schedule for cardiac surgery]

Area of Science:

• Cardiovascular Surgery
• Transfusion Medicine
• Healthcare Management

Background:

• Blood donation is a valuable resource requiring careful management.
• Excessive blood demand increases crossmatching and component loss.
• A maximum surgical blood order program (MSBOS) is crucial for optimizing blood use in surgery.

Purpose of the Study:

• To develop and implement an MSBOS at a specialized Cardiology Hospital.
• To evaluate the impact of the MSBOS on blood component utilization.

Main Methods:

• An observational, longitudinal, ambispective, and comparative study was conducted over one year.
• Patients undergoing cardiac surgeries were included.
• Key metrics such as crossover/transfusion ratio (C/T), transfusion probability (T%), and transfusion index (TI) were calculated and analyzed using descriptive statistics and the Wilcoxon test.

Main Results:

• The study analyzed 533 cardiac surgeries across 58 elective procedure types.
• Significant improvements in C/T, T%, and TI were observed for specific surgeries, including hemodynamic ablation, ASD closure, decortication, MCP, tracheostomy, heart transplantation, and pericardial window procedures.
• The implementation of the MSBOS demonstrated positive impacts on key transfusion indices.

Conclusions:

• The development and implementation of an MSBOS in a Cardiology Hospital led to improved blood utilization indices.
• The MSBOS facilitates the evaluation and optimization of blood component administration.
• This program is essential for ensuring the appropriate and rational use of blood resources in surgical settings.
