Assessment of levels of awareness towards blood donation in Saudi Arabia

Abstract

Background

blood products is an interesting term as all blood and blood transfusion procedures carry risk even with advance screening of donors and donated blood. In Saudi Arabia voluntary donors are either the only source or not, the other source is paid donors and the lack of volunteers represents a major challenge. This is usually attributed to low community awareness regarding voluntary blood donation. Therefore, the objective of this study was to assess the levels of awareness towards blood donation in northern Saudi Arabia.

Methodology

in this descriptive cross sectional survey, data about blood donation were obtained from 717 Saudi volunteers living in the city of Hail, Saudi Arabia. A Purposeful questionnaire was designed and used for obtaining of the necessary data.

Results

When asking the participants to rate the level of awareness about blood donation in Saudi Society, the majority of participants categorized the levels as good followed by very good and poor, representing 48.8%, 29.3%, and 22% participants, respectively.

Conclusion

the broad concept of blood donation is still poor in Saudi Arabia. Further educational plans are needed to raise the level of awareness and increase the perception of blood donation among Saudi population. Efforts should be made to involve females in blood donation duties.

1. Introduction

Blood donation (BD) is considered as a typical altruistic behavior, and recruitment/retention campaigns give emphasis to altruism. Here, a benevolence hypothesis for blood donation (both the donor and recipient benefit) rather than the altruism hypothesis (only the recipient gains) is proposed [1]. While BD is traditionally described as a behavior motivated by pure altruism, the assessment of altruism in the BD literature has not been theoretically informed [2]. The World Health Organization (WHO) encourages that blood donation becomes voluntary and unremunerated [3]. The benevolence hypothesis (both donor and recipient gain) suggests that blood donors, compared to non-blood donors have a general altruistic motivational preference based on warm glow (i.e., “I donate because it makes me feel good”) [4]. The benevolence hypothesis is supported, suggesting that blood donor motivation is partly selfish. Blood donation campaigns should focus on benevolent rather than purely altruistic messages [1].

In a meta-analysis sought to identify the strongest antecedents of blood donation behavior and intentions. It synthesized the results of 24 predictive correlational studies of donation behavior and 37 studies of donation intentions. The antecedents were grouped into six categories: (1) the Theory of Planned Behavior (TPB) and its extensions, (2) prosocial motivation, (3) affective expectations, (4) donor site experience, (5) past donation behavior, and (6) donor demographics [5]. Retention of blood donors has benefits over recruitment of new blood donors. Retention is defined as preventing donors from lapsing and eventually becoming inactive. Studies have found that intention to donate, attitudes towards blood donation and self-efficacy (does one feel capable of donating blood) are predictors of blood donation [6].

In the Kingdom of Saudi Arabia (KSA) the blood transfusion service is basically a hospital-based blood banking system where blood banks are responsible for the whole service, including the recruitment of donors, testing donated blood. The source of donated blood is a combination of direct donation (mainly relatives, friends and workmates of patients), and a growing number of voluntary non-remunerated donors [7]. However, there are other possibilities including blood donation campaigns, regional blood banks and Red Crescent.

Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation [8]. Therefore, the objective of the present study was to assess the levels of awareness toward blood donation in northern Saudi Arabia.

2. Materials and methods

2.1. Ethical consent

Each participant was asked to sign a written ethical consent during the questionnaire's interview. The informed ethical consent form was designed and approved by the ethical committee of the College of Medicine (University of Hail, Saudi Arabia) Research Board.

In this cross sectional survey, data about blood donation were obtained from 717 Saudi volunteers living in the city of Hail, Saudi Arabia. Participants were randomly selected by simple random regardless to age, gender and education or occupation. The participants were recruited from different public gathering places, including educational entities, clubs and others. Data were obtained during face-to-face interview.

A Purposeful questionnaire was designed and used for obtaining of the necessary data. The following information were obtained from each participant: age, sex, education level and occupation sector. Questions regarding awareness about blood donation were also included, which comprised: The source of knowledge about blood donation, rate the level of awareness about blood donation in Saudi Society, does blood donation has beneficial effects for the donor? Donation decreases heart and arterial diseases, during donation you can detect hidden diseases, does blood donation is an important issue, if there is announcement for rare blood group and you possess it will go? The frequency of blood donation, do you know the benefits of blood donation, donation can activate blood circulation and blood renewal, during donation you can detect diseases, does the blood donation important? The factors motivated for blood donation are?

The term “free work” in the study means: self-employed and jobless. Public gathering Include: what is locally called “Diawania”, clubs etc.

2.2. Data analysis

Statistical Package for Social Sciences (version 16) was used for analysis and to perform Pearson Chi-square test for statistical significance (p value). The 95% confidence level and confidence intervals were used. p value less than 0.05 was considered statistically significant.

3. Results

The requirement for blood transfusion is very high in Saudi Arabia, due to high rates of road traffic injuries [9], beside regular need in health services. Thus, blood donation represents an important issue in the health system in Saudi Arabia. Therefore, the aim of the present study was to assess the level of awareness towards blood donation in a random community based study in Northern Saudi Arabia. This study included individuals with diverse demographical characteristics in term of sex, age, education and occupational sectors.

With regard to the source of knowledge about blood donation, the most effective sources were social media and public gathers rather than the awareness efforts accompanying the blood donation campaigns. Beside the traditional public gathering places such as clubs, education entities and cafés, in Saudi Arabia there are other public gathering entities, such as mosques and Estraha (special building for spending leisure time with friends, particularly at night or during vacations). However, the implementation of effective communication interventions represents a major public health issue. Nevertheless, persuasive media campaigns appear to have little effect on behaviors. Even though non-donors hold a positive attitude towards blood donation, they are not inclined to donate. As an alternative to producing behavioral changes, many recent studies have shown the superiority of binding communication over persuasive communication [10].

In the present study, the majority of the surveyed individuals believed that the level of awareness toward blood donation is good among Saudi people. This might be implicit in term of response, since the majority of Saudi people think that helping others is religious obligation. Religion is deeply rooted in the Saudi society and it was assumed to be a major motivating factor for blood donation [7]. Consequently, other factors, which motivates blood donation should be implemented within awareness campaigns in Saudi Arabia.

In context of the beneficial effects of blood donation, high proportions of the participants have emphasized that blood donation has beneficial effects to the donor. According to some studies blood donors have a lower risk of cardiovascular incidents. This may be associated with the risk of cardiovascular disease reported by some authors, as well as with the oxidative changes caused by iron [11]. Regular blood donation may be protective against cardiovascular disease as reflected by significantly lower mean total cholesterol and low-density lipoprotein levels in regular blood donors than in non-donors [12]. Endothelial dysfunction, secondary to systemic inflammation and oxidative stress, is known to play a major role in the development and progression of atherosclerosis. It was found that regular blood donation is associated with improved endothelial function in healthy adult males [13]. Though there reasonable number of Saudi population know the beneficial effects of blood donation, still there is a need to extend this knowledge to large section of Saudi people.

In the present study we found that the majority of participants were rarely donate blood, particularly females. Saudi females constitute less than 5% of blood donors. The attitude of Saudi female students towards blood donation is positive and few misconceptions that emerged could be corrected by health awareness campaigns [14]. However, similar study from Saudi Araba has concluded that the prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals' places of work to reduce their time costs of donating is a necessity [8].

With regard to education, the great majority of participants in the present study were from relatively higher educated people. This may the risk of getting more positive attitude towards blood donation than those selected as cross-sectional varieties. This might be considered as a limitation in the present study.

On the other hand, in the current study we measured different blood donation related factors in association with influence of occupation. Also we found that most participants were clustering within certain occupation, particularly education sector and military. With our strong proposing that some of these occupations have influence in raising blood donation awareness, but our sample selection may not enable us to draw specific guessing in this context.

Although the present study has provided a huge data for future planning of blood donation strategies, as well as stimulating other studies, it has some limitations, particularly in sampling planning.

7. Conclusions

The broad concept of blood donation is still poor in Saudi Arabia. Further educational plans are needed to raise the level of awareness and increase the perception of blood donation among Saudi population. The best use of social media and public gathering should be implemented in blood donation strategies. Efforts should be made to involve females in blood donation duties.
