Abstract

Background
Due to the importance of the cold chain related to vaccine transportation, it is necessary to establish a blood cold chain operation strategy by checking the status of blood transportation from blood donation to transfusion.
Methods
The blood transportation system and blood storage facilities were checked by inspecting the Korean Red Cross (KRC) Blood Centers and its affiliated supplier and Hanmaeum Blood Center. The status of the cold chain was evaluated through an interview with the quality control manager or blood supply team leader. For the hospital, the status was investigated from the perspective of the 30-min rule. A questionnaire survey was conducted for medical technicians and nurses working at the hospital.
Results
Data on temperature during transport of blood components were computerized, and all standards were met. A nationwide network that could supply blood from the blood supply center to the hospitals within 2 hours was established. The frequency of temperature monitoring in the blood transport box and constant temperature check in the transport box during long-distance transport were evaluated.
Conclusion
This study confirmed that blood storage and transportation in Korea complied with the cold chain standards of high-income countries or higher. The evaluation of the cold chain is a constantly evolving process requiring continuous attention. When standards for storage and transportation of blood products are established, strict regulations and examinations will be required.
