The authors’ aim was to assess the level of knowledge, attitudes, and practices (kap) regarding blood donation among workers after an occupational health nurse-initiated education.Material and methods. The authors providing educational brochure on blood donation via company-wide intranet and com-pany newsletters, then the survey was conducted between august and december 2010 in a major company, using a convenience sampling method. in the course of the survey an anonymous, self-completion questionnaire has been developed based on the eurobarometer 41.0 (1995): europeans and blood, supplemented with the authors’ own questions. They used mixed-mode data collection: traditional paper-based questionnaire and web-based survey. The authors analysed the gathered data with Microsoft excel 2003 software, using a descriptive statistical method and chi-square tests.Results. The survey was completed by 483 self-registered workers. The sample consisted of 63% male and 37% female. The respondents were between the ages of 18-60 years. 68% of the sample judged their state of health to be very good or excellent. 82% of respondents were donors. after the education more than three quarters (88%) of total respondents had good knowl-edge of blood donation. 53% of the respondents cited the company internal communication as main source of information regarding blood donation.Conclusions. The authors stress the importance of educating and informing workers, because based on the results it can be con-cluded that education by occupational health nurses can positively contribute to strongly increase kap towards blood donation among workers and might lead to higher blood donation rates.key words: occupational health nurse, blood donation, educationINTRODUCTIONBased on literature review, it can be stated that blood donation is a highly relevant issue worldwide (1, 3-6). For the safe and continous blood supply it is essential to recruit healthy and dependable donors, who lead a lifestyle of low-risk of getting infected and donate blood regularly (1, 6). In these days one of the main aim is to increase the awarness of the general population re-garding blood donation. Findings of earlier researches showed that the greater part of donors are under em-ployment (1, 5). Occupational health nurses (OHN) are at the frontline in helping to protect and promote the health of working populations. Although workplace health promotion is a core concept in occupational health nursing there was no study referring to promotion of blood donation among workers from the occupational health nurses’ point of view.AIMThe intention of the survey is to determine the level of knowledge, attitudes, and practices (KAP) regarding blood donation among workers after an occupational health nurse-initiated education. Our hypothesis was that education can increase the KAP level in order to en-large the number of possible blood donors in the future.MATERIAL AND METHODSAfter providing educational brochure on blood do-nation via company-wide Intranet and company news-letters a survey was conducted between August and 133New Medicine 4/2013The effects of occupational health nurse-initiated education on workers knowledge, attitude and practice regarding blood donationDecember 2010 in a major company in Hungary, using a convenience sampling method. In the course of the survey an anonymous, self-completion questionnaire has been developed based on the Eurobarometer 41.0 (1995): Europeans and Blood (EB41.0), supplemented with our own questions (3). The original version of the questionnaire was prepared in English language. In a first step we translated it into Hungarian. The results of this first translation were checked by a group of Eng-lish speaking native Hungarians. The new version was translated back to English language by a professional translator (native English speaker). The differences be-tween the re-translated English version and the origi-nal English version were examined and discussed. On the basis of the comments made, a third version of a questionnaire (pre-test) was designed. Following an internal testing the survey was pilot-tested in a con-venience sample of 15 individuals from the company. The purpose of this pilot study was to determine item clarity for the participants. The results of the pilot-test showed the adequacy of the data collection instrument for the proposed research objectives. The final survey had 20 questions. The survey is composed of three sec-tions: (a) socio-demographic background, (b) knowl-edge about blood donation, and (c) attitude regarding blood donation. We used mixed-mode data collection: traditional paper-based questionnaire and web-based survey. Paper-based questionnaire were distributed to workers visiting the company’s occupational health units and via the company’s Intranet. As the survey was anonymous there was no follow up of respondents. To increase the participation rate, two reminder pop-up messages were placed on the company’s Intranet web-page after two months, and 15 days before the closing date of the survey. For the purposes of our analysis, both the paper-based (N = 180) and online (N = 303) responses are combined in a joint database. The analy-sis was performed applying descriptive statistical meth-ods and chi-square tests, calculated by Microsoft Excel 2003 software.RESULTSThe information in this survey has several limitations that must be considered when reading the data. The major limitations of the survey is that the response rate was N = 483, and it relies on a mixed-mode self-report method of data collection. It allows less control over the number and type of participants and it is possible that certain groups of workers did not have access to the intranet. These may slightly limit the generalizability of the survey results.As the size of the population to which the survey was circulated is unknown due to the distribution network, it is not possible to calculate response rates for the sur-vey. The survey was completed by 483 self-registered workers. Table 1 shows some socio-demographic char-acteristics of the studied workers with significance lev-els. A total of 394 (82%) workers had donated blood at least once in the past. Of blood donors 45 (11.42%) had only donated once, 133 (33.75%) had given blood a few times, and more than half, 216 (54%) were regular re-peat donors. The majority of donors 301 (76.4%) had given blood during the past six months, 65 (16.5%) had given blood within a year, 28 (7.1%) had last attended a session over a year ago. The main motivational factor for donation was sense of mural duty for almost half, 189 (48%) of the donors.18% of the total respondents have never given blood. Of those who had never given blood the majority (64.4%) had thought to do. The main reason for not donating blood was lack of time to donate (56.6%). Other reasons were fear of needles (18.3%), medical problems (10%), fear of infections (8.3%) and all other reasons were few-er than 5%. 3.72% of studied workers have had a blood transfusion.Table 2 shows the level of knowledge of the stud-ied workers. After an OHN-initiated education more than three quarters (88%) of total respondents had good knowledge of blood donation. The maximum aware-ness was about blood transfusion is blood type-specific (99.8%), whereas the minimum awareness was about maximum age exist for blood donation (55.3%).Figure 1 presents the knowledge of the participants in the current study about available blood supply in the blood banks. Moreover, the majority of respondents (89%) think, that the safety of transfusion has improved over the past ten years.Survey respondents were asked about the main source of information regarding blood donation. 53% of respondents cited the company-wide Intranet, company magazine and posters at workplace. Media (television, radio, media website, newspapers) was cited as the main source of information by 38% of respondents. 7% cited discussions with family, friends and colleagues and 2% cited social networking sites (Facebook, iwiw, etc.).DISCUSSIONSeveral investigations and statistics were done on blood donor’s KAP, which mainly focus on the main sources of potential blood donors in order to motivate them via direct contact (1, 5, 7). We think, OHNs luckily in a specific position to involve more workers for blood donation. Our hypothesis was to test this idea in a large Hungarian company, which started to participate in blood donor campaigns initiated by an OHN.The company’s OHN edited several educational bro-chures, articles, and advertiesement on blood donation via company-wide Intranet and newsletters, which were followed by our present analysis. This was not surpris-ing, information provided by the company-wide Intranet motivate potential donors mainly (53%) due to micro-social attitude effects; in contrast with EB41.0, where mass-media: mainly TV, general newspapers, and radio took the main contribution. In this latter study, workplac-es as a source of information was negligible.Socio-demographic content of our sample (tab. 1) fit to the studied group by EB41.0, however 82% of our sur-vey respondents had donated blood previously instead 134 New Medicine 4/2013Henriett Hirdi, Veronika Rajki, Judit Mészárosof 30% within the EU12. This percentage is higher than recorded in other studies also. E.g. the latest Eurobarom-eter 72.3 (EB72.3) carried out in 2009, in the 27 EU Mem-ber States, showed that only the 37% of the European cit-izens had previously donated blood, while in Hungary the average was 44%. (4) Our sample donor group was male dominated (68%) and the willingness of blood donation was found to be decreasing with the age significantly in accordance with a German survey (7). Higher education level and urban life effect positively on the willingness to donate (1, 2). Family- and children-related surveys influ-ence blood donation habit, but not significantly. It was also interesting, that the self-rated health status of the 98% respondents were good or higher.Table 1.

The majority of our respondents (89%) think that the safety of transfusion has improved over the past ten years, compared to 57% (EU27) and 51% (HU) recorded in the EB72.3 (4). Based on figure 1 it was con-cluded that the studied workers are well informed about blood supply level at blood banks also. 64% knows that stored blood amount is less than needed.The present research shows that after an OHN-initiat-ed education the level of the knowledge of the popula-tion under study regarding blood donation was higher in comparison with the general knowledge in this field.CONCLUSIONSOccupational health nurses can greatly contribute to safe national blood supply by identifying and advis-ing potential blood donors. The authors stress the im-portance of educating and informing workers, because based on the results it can be concluded that education by OHNs can positively contribute to strongly increase KAP towards blood donation among workers and might lead to higher blood donation rates.References1.
