Haemovigilance: A Current Update in Indian Perspective

Proposing a Model for the National Hemovigilance Information System in Iran

The present study aimed to propose a model for the national hemovigilance information system with a database approach, considering the importance and necessity of developing an information system for such a network.

This is an applied, descriptive, and cross-sectional study, which was conducted in 2018. The research population comprised hemovigilance information systems in advanced countries, including the USA, UK, Australia, and France. Data were collected from library sources and the Internet from 2000 to 2018. The proposed model for the national hemovigilance information system was introduced using comparative tables and based on the similarities and differences of systems in the studied countries. The proposed model was then validated using the two-step Delphi technique through a researcher-made questionnaire whose validity was confirmed, and reliability was approved by a Cronbach’s alpha of 94%.

The final model of the national hemovigilance information system comprised five main components: goals, organizations involved in the blood transfusion process, databases of blood transfusion organizations, data transfer flow between the databases of blood transfusion organizations, and transferable datasets, and hemovigilance-related committees. This model was approved by experts with an >85% agreement coefficient.

The national hemovigilance information system with a database approach can improve blood transfusion health by providing access to reliable sources on blood transfusion complications to everyone, especially the medical community. Thus, it is essential to implement this standard accurately and precisely control the practical methods of this process based on international guidelines.

Knowledge of Blood Transfusion in Medical And Biology Students

Introduction: Blood transfusion (hemotherapy) is a therapeutic intervention used in treatment strategies of multiple diseases, thus, proper education is of utmost importance. Since currently there are no specified educational programs, undergraduate students were evaluated for the knowledge gained during university courses.

Purpose: To evaluate and compare the level of knowledge of students of the faculty of Health Science, Department of Medicine (DM), and Department of Molecular Biology-Genetics (DMB&Gs) on issues related to the transfusion of blood products.

Methods: A cross-sectional observational study was carried out with 123 students from the aforementioned departments of the Democritus University of Thrace, from the third year to the last year of study. A questionnaire was used, weighted, and was based on the European Commission's Guide to the Preparation, Use and Quality Assurance for Blood Components. Statistical tests such as chi-square (χ2), t-test, analysis of variance (ANOVA), and linear regression were used to investigate the factors that affect the overall score.

Results: The mean score of the students was 42.55 while the standard deviation (SD) was 12.27. The difference in the scores between the students of the DM (M = 44.63, SD = 13.2) and those of the DMB&Gs (mean = 38.25, SD = 9.05) was statistically significant in the univariable analysis (t= 3.1, p = 0.0), but in the multivariable analysis, it was not statistically significant (β = -4.1, p = 0.1.). The results of the multiple regression model indicated that the year of study, the professional status of the father, and the grade in the hematology course were associated with the total score.

Conclusions: The level of knowledge regarding blood product transfusion among students of the faculty of Health Science is insufficient.
