Summary
Pretransfusion testing varies significantly across Korean hospitals. Primary hospitals and clinics require improved practices for safe blood transfusions, highlighting disparities in utilization.
Area of Science:
- Transfusion Medicine
- Clinical Pathology
- Health Services Research
Background:
- Nationwide assessment of pretransfusion testing utilization is complex.
- This study evaluates pretransfusion testing practices in Korea using insurance claims data.
Purpose of the Study:
- To analyze the current status of pretransfusion testing utilization across different hospital types in Korea.
- To identify disparities in testing methods and adherence to guidelines.
Main Methods:
- Analysis of nationwide insurance claims data from January 2011 to December 2020.
- Examined ABO/RhD typing, antibody screening, identification, and crossmatching by hospital type.
- Compared automated versus manual testing methods and transfusion protocols.
Main Results:
- Significant differences in ABO typing ratios and automation adoption were observed between tertiary/secondary hospitals and primary hospitals/clinics.
- Lower antibody identification to screening ratios in primary hospitals and clinics.
- A high percentage of initial red blood cell (RBC) transfusions in primary hospitals and clinics occurred without antibody screening.
Conclusions:
- Pretransfusion testing practices vary considerably by hospital type in Korea.
- Primary hospitals and clinics demonstrate a need for enhanced education and improved practices to ensure safe blood transfusion services.

01:28Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
