[Professional knowledge and practice mapping among nurses regarding transfusion therapy. A pilot study on reliability and validity testing]

All people involved in transfusion therapy have professional, legal and ethical responsibility for their own actions.

The aims of the authors were to evaluate competencies, knowledge and practice of nurses about transfusion therapy.

Descriptive statistical approach using observation, questionnaire survey and interview was applied. Reliability and validity of the self-made questionnaire were examined with statistical methods. Variance, standard deviation, Cronbach's alpha and Pearson correlations were calculated.

Transfusiology-related knowledge of nurses regarding current transfusion regulations was almost 90%, and 56.2% of nurses systematized the nursing functions correctly. Significant differences were found among different institutions in transfusion therapy, transfusion practice and the use of relevant documentation. 75-77% of the institutions examined had their own protocol, and assigned transfusion care nurses worked in more than 20% of the wards.

The authors propose a better supervision by leaders in nursing aspects of transfusion therapy, and an increased professional responsibility.
