RESUMEN
BACKGROUND: Transfusion guidelines play an important role for the appropriate use and quality assurance of blood and transfusion services. The Korean national transfusion guideline was developed in 2009 and went under full amendment in 2016. The purpose of this study was to investigate the awareness and practicality of the transfusion guideline in Korea. METHODS: Questionnaires about the Korean national transfusion guideline were sent by traditional mail or e-mail to a total of 1,179 clinicians, 32 academic societies, and 6 institutions. RESULTS: Three hundred and seventy-four answers were received; a response rate of 30.7%. The proportion of respondents with good awareness of the guideline was 23.3%, which is a significant increase compared with 10.9% in 2008. Respondents with good awareness were more dependent on the transfusion guideline when making transfusion decisions. CONCLUSION: There was a considerable increase in the awareness of the national transfusion guideline in Korea.
