The main goal of blood transfusion organizations is to maintain a stable supply of blood. Managers should use strategies such as marketing and donor behavior management to attract and retain donors. The aim of the research was to investigate the effect of goal-related marketing and personal norms on the intention to donate blood again in clients of Karaj Blood Transfusion Organization.

In terms of the logic of the research implementation, the current type of research is of a comparative type, in terms of the implementation process, it is of a quantitative type, and in terms of the purpose of the research, it is an analysis in the paradigm of positivism. Due to cross-sectional time, in terms of the method of data collection, it was a survey type, and in terms of the results and consequences of the research, it was of an applied type. The research tools include standard marketing questionnaires related to the goal of Lee et al. (2021), personal norms by Wang et al. (2018), the intention to donate blood again by Boenik and Saltzman (2018) during a simple random sampling of the data of 391 donors using descriptive statistics. And the regression tests were analyzed by structural equation modeling.

Validity, reliability and quality indicators of the model were acceptable. Target-related marketing (T=4.501, Beta=0.182) and personal norm (T=12.916, Beta=0.487) had a significant effect on the intention to donate blood again.

According to the findings of the research, it is expected that the intention to donate blood will increase as a result of marketing related to the goal and personal norms of the donor. Therefore, by investing in target-related marketing and strengthening the personal norms of donors, the blood transfusion organization can expect to increase the intention to donate blood again.

Evaluating the attitudes and beliefs of different classes of society is very important in attracting donors. This study aimed to evaluate the attitude of students of Alborz University of Medical Sciences regarding blood donation and investigate the obstacles in this field.

A descriptive cross-sectional study was conducted on 330 students of different fields of Alborz University of Medical Sciences in 2023. A questionnaire containing demographic questions and main research questions (12 questions to evaluate the causes of blood donation-7 questions to evaluate the reasons for not donating again in donors - 20 questions to evaluate the factors preventing blood donation in non-donors-12 questions about the general attitude to blood donation in donors and non-donors) were used to collect data. Data analysis was done with SPSS21 software and descriptive statistics.

The average age was 22.85 ± 0.26 years and only 11.5% had history of donating blood. The most important motivating factors include altruistic causes (100%), feeling of responsibility (96.9%), moral and personal commitment (87.5%), participation in social activities (75%) and helping patients (71.9%). The most important reasons preventing blood donation are fear of dizziness and weakness (77.2% and 64.1%, respectively), lack of proper information (67%), fear of hand burning and hematoma (42.4%) and fear of anemia (47.8%).

Conclusions  :

Despite the low donation rate, most students had a positive attitude towards blood donation. In order to encourage students to donate blood, the necessary information should be provided through holding appropriate educational programs.

Nowadays, it is necessary to evaluate the prevalence of HBV and HCV viruses all around the world due to the importance of preventing infections transmitted through transfusion of blood products. In this study, we investigated the prevalence of these two viruses that cause viral hepatitis among blood donors in Sistan and Baluchestan province.

This retrospective study is conducted on blood donors in Sistan and Baluchestan province in order to evaluate the prevalence rate and trend of Hepatitis B and C during the years 2011-2022. The data were analyzed using Mann–Whitney U test, chi-square (χ2), and SPSS 22.

The prevalence rates of hepatitis B and C infections among blood donors were 0.329% and 0.05%, in Sistan and Baluchestan province respectively. During the years 2011 to 2022, the prevalence of hepatitis B infection decreased from 818 cases per hundred thousand people in 2011 to 109 cases in 2022. Similarly, the prevalence of hepatitis C decreased from 102 cases in 2011 to 27 cases in 2022.

Conclusions :

The results of the present study indicated a decrease in the prevalence of hepatitis B and C infections over a decade, which can show the effective trend of health indicators and prevention programs of HBV and HCV.

Considering the lower-than-expected participation of women in donating blood, it is necessary to encourage them to do so. In this regard, the preparation of appropriate and effective trainings requires the identification of effective factors in women blood donation. This study has investigated the relationship between the constructs of the theory of planned behavior and injection anxiety in female students of Isfahan University of Medical Sciences.

This descriptive-analytical study was conducted with the participation of female students of Isfahan University of Medical Sciences in 2022. Six hundred and twenty-three students were selected by stratified multi-stage quota sampling method and the data related to the constructs of the theory of planned behavior and trypanophobia were collected through an electronic questionnaire with SPSS/20 software and coefficient tests. Pearson correlation and linear regression were used for data analysis.

The results showed that 114 female students (18.3%) had a history of donating blood. There was a direct relationship between the constructs of awareness, mental norms, perceived behavioral control and attitude with the intention to donate blood; injection anxiety had an inverse relationship with the intention to donate blood (p ≤ 0.001).

The theory of planned behavior can be a suitable model for conducting interventions to encourage women to donate blood; on the other hand, using different educational programs to reduce injection anxiety and treat anemia in women in order to increase blood donation seem necessary.

Today, despite scientific developments and important medical advances, the supply of healthy and sufficient blood is still one of the biggest concerns of the health system, and one of the most important needs of health and treatment centers and many victims of accidents, war wounded, and needy patients. The issue of supplying blood and blood products in the important wars of the contemporary era has been a big challenge for the countries involved in the war and many injured people have lost their lives due to the lack of timely supply of blood. With the beginning of the invasion of the Iraqi Baath army on 31st of September 1359 against the land of dear Iran, the need for blood for the treatment of the wounded increased greatly, and in addition to the Iranian Blood Transfusion Organization, the Red Crescent Society has also made significant efforts in this field. By forming a joint relief and treatment committee, this population played a significant role in providing blood in addition to medical and relief measures. However, the main role of blood supply at this time was the responsibility of the blood transfusion organization, and practically, the centers of the Red Crescent population alone were not able to respond to the significant reception of the people. This study was conducted using the method of reviewing and analyzing the content of the published papers and official reports by related bibliography and websites.

Risk is a combination of the likelihood of an incident occurring and the severity of the consequences if that incident were to occur. The aim of this research is to identify and evaluate the risk factors in the blood donation process in a fixed blood collection center of Saqez city by failure mode and effects analysis (FMEA).

It is a descriptive-applied study that was performed in a fixed blood collection center of Saqez in 2020. The researcher collected and analyzed the data using FMEA worksheets. Then the risk priority number is obtained by multiplying the three indicators of failure severity (S), the failure probability of occurrence (O), and the failure detection (D). Finally, the priority was based on the failures.

Finally, 30 sub-processes were identified, of which 20 sub-processes with acceptable risk and 10 sub-processes with unacceptable risk were identified. The highest identified risk is related to the donor not paying attention to safety points before and after blood donation with a priority risk number of 168 and the lowest is attributed to the shaker not alarmed when the blood donation process ends with a RPN of 48.

Many of the failures identified will be reduced or eliminated by training, providing up-to-date equipment, and changing procedures and working methods.

Hypertension is one of the most important preventable risk factors for cardiovascular disease. This observational study aimed to depict the role of regular blood donation on the systolic and diastolic blood pressure (SBP and DBP, respectively) in hypertensive patients in comparison with normotensive people.

This study was performed as a cross-sectional descriptive study on 546 blood donors of Vesal Blood Donation Center in Tehran who donated between 1 and 4 times in the period of 2016-2017. Donors were divided into two groups (hypertension and normal blood pressure) based on the systolic blood pressure (SBP) and diastolic blood pressure (DBP) at the time of the first donation. The trend of changes in blood pressure after each donation (second, third and fourth donation) was assessed using SPSS ver. 16 and One way-Anova statistical test.

In the group of hypertensive patients,, after four blood donations, systolic and diastolic blood pressure showed a statistically significant decrease after three or four donations.
Systolic blood pressure in this group after the fourth donation decreased from the mean of 149.1 to 141.6 mm Hg (P = 0.03) and diastolic blood pressure decreased from 90.04 to 86.08 mm Hg (P = 0.04 also), respectively. Decreased blood pressure was also observed in the normal group, although this significant decrease was not reported (P> 0.05).

Our results corroborated a down-regulatory effect of regular blood donation on BP in hypertensive people.  These findings are rather encouraging people toward voluntary blood donation and can be considered in therapy-related issues.

Non-alcoholic liver disease (NAFLD) is a spectrum of diseases, ranging from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH) which can lead to liver cirrhosis and hepatocellular carcinoma. Nonalchololic fatty liver  is the most prevalent hepatic disorder worldwide which can affect up to the one out of four adults. Little is known about the prevalence of nonalchololic fatty liver among regular donors of blood products. The current study shows the prevalence of nonalchololic fatty liver  in regular plasma and blood donors with a discontinuous donor population.

In this case-control study, we non-randomly enrolled 400 volunteers of blood donors who met the blood donation criteria after signing the written informed consent. All patients underwent hepatobiliary ultrasonography to evaluate fatty liver. LFT (Liver Function Test) and demographic criteria had been submitted in data base. All data were described by central dispersion indices and analyzed by Mann-Whitney U test and chi-square.

No difference was seen regarding gender and mean age between groups (p-value of 0.441 and 0.635, respectively). According to univariate analysis there was no significant difference between the two groups regarding the prevalence of fatty liver (p= 0.264) or its staging (p= 0.9). In addition, OR and RR were 1.17 and 1.11, respectively; both not being significant (p= 0.461).

The prevalence of NAFLD has no significant correlation with both regular blood donors and non-regular blood donors.

Education has an essential role in the community awareness that could increase the blood donation tendency and reduce the risk of unsafe blood donation. The present study assessed the role of education and removal of blood donation barriers in increasing blood donation and promoting blood safety among students of Zahedan universities.

This Descriptive-interventional study was conducted in five universities and high education centers in Zahedan City. At the beginning, the questionnaire was used to identify the main barriers of blood donation among these students. Then we tried to resolve the studentschr('39') major concerns through education. Finally, the mobile blood collection teams were sent to these universities. The percentage of first-time blood donors and the safety of donated blood units were compared with those of the main blood transfusion center.

The main reasons for lack of blood donation among the 2744 students were fear of endangering their health (44.8%) and lack of enough time (26.7%). After the education was provided, 1211 individuals including 1039 (85.8%) men and 172 (14.2%) women donated blood, The number was much higher than that in the main blood transfusion center of Zahedan City (p < 0.01). The number of the first-time donors as well as the rate of blood safety were significantly higher (p < 0.001) among these donors than those in the main blood transfusion center of Zahedan (p < 0.001).

The present study showed that education plays a very important role in increasing blood donation rate and promoting blood safety

To encourage women to embark on blood donation, the opinions and factors that impede blood donation should be identified. The purpose of this study was to investigate factors affecting participation of women in blood donation.

In this cross-sectional study, the questionnaires were completed by 250 female staff of Tabriz University of Medical Sciences. Data were analyzed using Pearson correlation, one-way ANOVA and regression analysis.

93.6% of people claimed blood donation is a humanitarian act, and 81.2% claimed "anemia" is barrier of blood donation. Regression analysis showed that there was a negative and significant relationship between knowledge and motivating factors that have impact on blood donation (p= 0.003), but barriers score did not show a significant correlation with women participation (p= 0.515). Based on the results of independent T-test, the relationship of marital status was not significant as compared with the knowledge  score (p = 0.834),  with  the  barriers score (p= 0.434), and with that of motivating factors (p = 0.615). Education level has not significantly correlated with the knowledge score (p = 0.510) but there was a significant negative correlation with barriers variable in blood donation (p = 0.17).

Conclusions :

According to the results, most of the participants in this study considered fear of anemia and fear of test results as barrier of blood donation. Therefore, establishing basic education and training programs to eliminate the wrong beliefs about blood donation would help encourage women as healthy sources of blood donors.

Creutzfeldt-Jakob disease (CJD) is a fatal brain disease caused by prions. Epidemiological evidence suggests the risk of transmission of CJD by blood products. The aim of this study was to identify common preventive strategies in blood services to avoid epidemic CJD between blood product recipients.

Published strategies on the official websites of blood collection centers of various countries with special attention to the prevention of CJD transmission during blood donor selection were reviewed.

In developed countries, donors with a positive history of CJD or vCJD for themselves or their first-degree relatives, individuals who have received a human-derived therapeutic products (including blood products) since 1980 in endemic countries for vCJD, or those with a history of residence in endemic parts of the world, for distinct cumulative exposure periods are excluded.

Iran has one of the healthiest blood donors in the world, and Iranian Blood Transfusion Organization policies are focused on supplying blood products from Iranian plasma donates, appropriate screening for CJD is recommended at every visit.

There is a circadian rhythm and diurnal variation in the redox capacity in blood plasma and there is a decrease in antioxidant capacity (TAC) during the RBCs storage in blood banking. So it is possible that donated blood, based on donation time, has a different antioxidant capacity and as a result a different biochemical response during storage. This study attempts to uncover this issue.
 

In this experimental study, Twenty RBC units were collected from two donor groups in the morning (8-11am) and evening (5-8pm) and were stored for 3 to 42 days at 4 to 8 degrees Celsius. Glucose, Sodium, potassium, lactate, lactate dehydrogenase (LDH), pH, malondialdehyde (MDA), and total antioxidant capacity were measured by a commercial kit. Nitrate/nitrite was measured by Griess method.
 

The levels of nitrate/nitrite, MDA, and LDH in the evening group increased significantly when compared to the morning group (p < 0.05). However, a decreasing trend in TAC, pH, Glucose, and sodium levels (p < 0.05) versus an increasing trend in potassium, lactate, LDH, and MDA was seen in both groups during storage (p < 0.05).

This study showed that oxidative damage in donated blood in the evening was higher than in the morning during storage, which may reduce RBC survival. Therefore, more studies are required with more sample sizes to examine the effect of donation time on the RBC storage lesion.

The main mission of blood centers is to provide safe and adequate blood products for patients. With the advancement of science and technology, the need for safe blood still has priority and no substitute for human blood is discovered. Participation in social activities such as voluntary blood donation should be provoked by different entities including public relations departments. The purpose of this study was to investigate the role of public relations departments in the motivation of citizens' participation in blood donation in Ardabil.
 

This cross-sectional study was conducted by multistage cluster sampling on 384 citizens over 18 years of age and using questionnaires in Ardabil. SPSS 22 data analysis software and regression data analysis were performed.
 

Donors aged between 18 and 60 years old participated in the study. Research findings showed that the mean rates of the role of public relations was 3.66 (Deviation 0.84), persuasive role 3.72 (Deviation 0.41), awareness role 3.60 (Deviation 1.46), problem-solving role 3.11 (Deviation 0.51), advisory role 3.45 (Deviation 0.48), the role of relationship management 2.80 (Deviation 0.57),  the role of public education 2.57 (Deviation 0.63). According to the findings, the mean rates of the citizen participation are 3.21 (Deviation 0.33), conditional behavioral participation 3.35 (Deviation 0.51), solidarity-oriented participation 3.36 (Deviation 0.73), and development-oriented partnership 3.22 (Deviation 0.78).
 

Dimensions of public relations (as persuasive, awareness, problem solving, advisory, relations management) in Iranian Blood Transfusion Organization has placed positive impact on the motivation of Ardabil citizens to participate in blood donation.
 

  Long-term preservation of the records requires a standard archive space. The purpose of this study is to examine the recent implementation of archival records in Iranian blood transfusion centers (BTCs) and to define effective corrective actions to improve current conditions.

In this descriptive cross-sectional observational study, a questionnaire consisting of 60 questions in four areas of infrastructure design, environmental control, archiving and health and safety was developed and was sent to 31 BTCs within the time frame from February to March 2017. Data analysis was performed using descriptive statistics (average and percentages) and SPSS 17.

The average frequency of positive responses in accordance with the requirements and standards was 73.13%. The monitoring of archive room temperature was carried out in 90.47% of BTCs. Nearly 73% of BTCs responded positively to compliance with relative humidity and ventilation control requirements. The average frequency of positive response of BTCs to establish the requirements of archival process was about 72.72%. Establishment of health and safety related parameters had the highest score among the four subjects (83.36%).

Despite the good state of implementation of requirements in the archive rooms for the infrastructure and health and safety, there are challenges in the field of temperature control and the archival process and document traceability, which resulted in effective corrective actions such as preparing the guideline for design requirements and archiving, defining the temperature and humidity limits and training BTCs to establish the necessary standards.

The most common type of reaction in blood donors is vasovagal reactions (VVRs). VVRs can negatively affect donor retention. The aim of this study was to assess the frequency of VVRs in Kurdistan Blood Center and impact of VVRs on donor return rates.

A descriptive cross-sectional study was conducted on the donors referring to Blood Center of Kurdistan province in 2015. In addition, donors who had VVRs were evaluated for return donation within 12 months. Results were analyzed by SPSS 16 software and Pearson's correlation was applied for analysis.

A total of 25891 blood donors were enrolled. Of the total number of donors, 170 (0.65%) experienced VVRs (157 male and 13 female); of these, 164 (95.9%) developed mild reaction, 3 (1.8%) had moderate, and 4 (2.4%) developed severe reaction. The mean age of female and male donors who experienced VVRs was 31.4 and 30.73 years, respectively. First-time donors (1.2%) had greater possibility to have a reaction. Donors with hemoglobin less than 15 gr/dl were significantly associated with VVR (p=0.004). The correlation of the body weight with VVR was significant (p=0.008). The return rate within 1 year was 18% (32/170) among donors with VVRs.

The results showed that the frequency of vasovagal reactions is higher in men with a greater weight loss than the minimum defined for blood donation
