Objective The emergence of evidence suggests that student nurses commonly exhibit concerns about their lack of knowledge of organ donation and transplantation. Formal training about organ donation has been shown to positively influence attitude, encourage communication and registration behaviours and improve knowledge about donor eligibility and brain death. The focus of this study was to determine the attitude and behaviour of student nurses and to assess their level of knowledge about organ donation after a programme of study.
Design A quantitative questionnaire was completed before and after participation in a programme of study using a pretest–post-test design.
Setting Participants were recruited from a University based in Northern Ireland during the period from February to April 2011.
Participants 100 preregistration nurses (female : male=96 : 4) aged 18–50 years (mean (SD) 24.3 (6.0) years) were recruited.
Results Participants’ knowledge improved over the programme of study with regard to the suitability of organs that can be donated after death, methods available to register organ donation intentions, organ donation laws, concept of brain death and the likelihood of recovery after brain death. Changes in attitude postintervention were also observed in relation to participants’ willingness to accept an informed system of consent and with regard to participants’ actual discussion behaviour.
Conclusions The results provide support for the introduction of a programme that helps inform student nurses about important aspects of organ donation.

Strengths and limitations of this study
Its novelty, as this is the first UK-based study that highlights the importance of formal instruction and demonstrates the merits of knowledge gains in key areas related to organ donation and transplantation and the need for effective communication with family members.
Findings were based on perceived knowledge rather than on actual knowledge and the use of self-reported measures to determine change in attitude and behaviour. It is based on a single cohort of student nurses.
The study was conducted on an ethnically and socio-economically homogenous group.
Organ donation is a unique social activity that has a direct influence on the delivery of healthcare to a wide range of patients. Transplantation and its known therapeutic benefits are not possible without the cooperation and support of healthcare professionals, government and society as a whole. Transplantation is the treatment of choice that improves life expectancy and quality of life.1 ,2 In addition, transplantation contributes to reducing healthcare expenditure.2–7 The donation and transplantation system represents a complex practice8 and is dependent on individual attitudes, social structures, cultural practices and religious beliefs. It is known that approximately 90% of the general public have a favourable view of organ donation.9 However, nurses have reported difficulties in being able to broach the subject of organ donation10 ,11 and as a consequence less than 55% of those likely to donate will be in a position to ultimately provide consent for donation.12 These inconsistencies serve to demonstrate that successful organ procurement fundamentally requires action on the part of the healthcare professional. Therefore, the attitude and approach of those healthcare professionals who procure organs for transplantation should not be dismissed as inconsequential. Nurses represent the largest group of such professionals13 and are the critical link within the transplantation system.14 Although it is recognised that not all nurses would be in a position to initiate the organ donation process, evidence suggests that nurses recognise that they have a crucial role to play in helping to support the process of organ donation and transplantation and in helping to raise its profile among the public.15 ,16
The emergence of evidence tends to suggest that nurses commonly exhibit concerns about their lack of knowledge and experience in dealing adequately with all aspects of organ donation and transplantation.10 ,11 ,17–24 It has been found that medical students possess limited knowledge about organ donation.25–27 This is likely to be because of the way in which organ donation and transplantation training is being delivered in a non-systematic manner from within other subjects.28 It has been noted that student nurses based in the USA frequently misunderstand the concept of brain death29 and that important issues related to brain death and cardiac death continue to be neglected.28 It has also been shown that there is a paucity of knowledge about how to initiate discussion about organ donation.28
It has been acknowledged that formal training about organ donation can successfully influence student nurses’ attitudes, encourage communication and registration behaviours and help improve knowledge about donor eligibility and brain death.30–32 Further improving knowledge about the organs suitable for donation, the methods available for registration and the regulations that govern the process of organ donation in the UK could help remove significant barriers and encourage engagement in prosocial behaviours.33 It is therefore important to ensure that those who may influence rates of transplantation are prepared and properly informed about the processes involved.
The objective of this study was to examine the attitudes and behaviour of student nurses and to assess their level of knowledge about organ donation before and after a programme of study. It is hypothesised that a programme of study can significantly improve knowledge and positively influence attitude and behaviour towards organ donation.
A pretest–post-test design was chosen to establish the impact of a programme of study on knowledge, attitude and behaviour involving two sets of cross-sectional data on the same population.
The researcher (DM) visited the university prior to starting the study so that background information could be provided and to help resolve any queries. Participation in the study was voluntary and without any form of compensation. Informed consent was obtained from all participants.
Setting and participants
Convenience sampling techniques were used to recruit preregistered nursing students undertaking a full-time degree course leading to the award of BSc (Hons). A total of 115 second year students were approached during the third trimester of a 3-year course of education at the University of Ulster, Northern Ireland. This sample was chosen because the population of Northern Ireland is relatively homogenous in terms of ethnicity, religion and socioeconomic factors. The cohort had recently completed a considerable proportion of their elective placements in general and specialist hospital care.
The participants completed a quantitative questionnaire based on previous validated frameworks.34–38 The questionnaire was further developed by several academic experts in the areas of biomedical science, mathematics and psychology and was extended to include additional concepts: attitude to registration and donation, knowledge about brain death, financial incentives and legislation. The questionnaire was then tested on a student nursing population in Northern Ireland and took into consideration the appropriateness of the content, use of language and sequence of questions. The questionnaire gathered demographic information on gender, age, country of birth, marital status and religious affiliation. Items in the questionnaire were categorised as two behaviour items, one willingness item, eight attitude items and six knowledge items (box 1).

How likely do you think it is that a brain dead person with a beating heart might recover and live?34 (very likely/likely/unlikely/very unlikely)
The programme of study
The participants completed a 33 h programme of study within the degree course that incorporated important issues relating to the clinical care of the potential organ donor as well as from the perspective of the transplant patient. The programme was designed to place an emphasis on the following areas: criteria for organ donation and what organs can be donated, nursing the potential organ donor and transplant patient and areas of potential risk, procedures involved in neurological assessment and management of brain injury, medical diagnosis of brain death, the legally accepted definition that leads to certification of death, effective communication strategies with donors and their relatives as well as recipients and their relatives, processes involved in procurement of organs and ethical aspects of organ donation and transplantation such as reasons for consent, respect for autonomy, beneficence and confidentiality. The importance of discussing intention to donate with family members was also covered. The programme of study was delivered to participants in a classroom setting with the whole student cohort gathered at the same time.
Data collection and analysis
Data were collected within an hour of start of the programme of study (February 2011) and after completion of the programme of study (April 2011). To determine whether the sample size chosen was adequate, a post hoc power analysis was conducted. The Exact tests option was chosen from the test family and two dependent groups (McNemar) selected as the statistical test in G*Power V.3.17. The power analysis demonstrated that the sample size (n=100) had an acceptable level of power (0.89) and was deemed adequate for the analysis.39
Descriptive statistics were used to assess demographic information, with the McNemar test chosen as the most appropriate tool for analysing dichotomous items from matched pairs of participants40 using the Statistical Package for Social Sciences (SPSS) V.19. It was decided that Yates’ correction for continuity should not be applied within a two-by-two contingency table. This is based on evidence suggesting that the corrected χ2 statistic is overly conservative and that the conventional statistic will provide adequate control over type I errors.41 ,42 A significant McNemar χ2 is an indication of a change between baseline and follow-up measurement.
Initially, 109 participants completed a questionnaire at baseline. Of these participants, 100 (91.7%) also completed a follow-up questionnaire; 9 (8.3%) failed to do so and were subsequently excluded from any further analysis. The final response rate was 87%.
Of the participants who completed both questionnaires, 96 were women which reflects the gender base of the profession.43 Ages ranged from 18 to 50 years (mean (SD) 24.3 (6.0) years). The majority of participants (n=82) were in their third decade, 5 in their second decade, 10 in their fourth decade, 1 in their fifth decade and 2 in their sixth decade. All participants reported religious (Christian) beliefs.
Knowledge about organ donation
Responses obtained from participants demonstrated significant changes in several key areas as seen in table 1. Knowledge about the suitability of organs that can be donated after death improved considerably (McNemar χ2=23.059, exact p<0.001) with 28% more participants able to correctly identify which organs are suitable for donation at follow-up compared with baseline measurement (95% CI 17.5 to 38.1). In particular, there was an improvement of knowledge in relation to the donation of corneal tissue: 96% of participants correctly understood at follow-up that the cornea is a tissue that can be successfully donated after death, compared with 72% at baseline (McNemar χ2=19.200, exact p<0.001; 95% CI 15.3 to 32.4). There was an increase of 24% in the number of participants who understood the methods available to register organ donation intentions subsequent to baseline measurement (McNemar χ2=24.000, exact p<0.001; 95% CI 15.3 to 32.4).
Following completion of the study, there was a rise in the number of participants who understood the laws relating to organ donation (McNemar χ2=11.636, exact p=0.001; 95% CI 7.0 to 25.3) and a statistically significant improvement in knowledge about brain death (McNemar χ2=11.560, exact p=0.001; 95% CI 7.5 to 26.4) and the likelihood of recovery following a diagnosis of brain death (McNemar χ2=5.538, exact p=0.019; 95% CI 1.9 to 22.0; table 1). However, 11% of the cohort continued to express doubts about this matter and believed that a person declared brain dead might subsequently recover and lead a normal life.
No statistically significant change was found with regard to religion and its supporting role in organ donation (McNemar χ2=2.000, exact p=0.157; table 1). Responses did not differ on the basis of willingness to register as an organ donor.
Willingness and behaviour towards organ donation
The number of participant's willing to register as an organ donor rose by 14.3% (baseline: 35 willing, 13 unwilling, 22 unsure; follow-up: 45 willing, 7 unwilling, 18 unsure). Participants also reported a 5% rise in the number currently registered (baseline: 33 willing, 67 unwilling; follow-up: 38 willing, 62 unwilling). However, the observed increases were not statistically significant. At follow-up, a greater number of participants (14%; 95% CI 6.9% to 20.8%) indicated that they had discussed their organ donation intentions with their family or friends compared with baseline measurement (McNemar χ2=14.000, exact p<0.001; table 2).
Attitude towards organ donation
A greater number of participants (16%; 95% CI 4.7% to 26.8%) favoured an informed system of consent at follow-up rather than opting for a change in legislation (McNemar χ2=7.529, exact p=0.006; table 3). The results indicate that the majority of participants at baseline (72%) and follow-up (70%) associated the process of registering as an organ donor with recognition of their own mortality and that support for the introduction of a government incentive scheme was low (baseline: 28%; follow-up: 27%; table 3). No statistically significant change was found with regard to perceived benefits of organ donation (McNemar χ2=2.000, exact p=0.157); medical distrust (McNemar χ2=0.000, exact p=1.000) and misappropriation of donated organs (McNemar χ2=0.100, exact p=0.752; table 3). The responses did not differ on the basis of willingness to register as an organ donor.
The results from this study support the conclusions of previous work that student nurses’ knowledge of organ donation can be substantially improved and that their discussion behaviours could be positively influenced by education about the topic.30–32 Statistically significant changes in knowledge about fundamental aspects of organ donation occurred in relation to the suitability of organs that could be donated after death, methods available to register organ donation intentions and organ donation laws and the likelihood of recovery following a diagnosis of brain death. Particularly notable were the improvements in understanding the fundamental medico-legal issues, namely how the law operates with regard to donation, the difference between informed and presumed consent and the fact that brain death is legally certifiable cause of death. Previous studies30–32 have suggested that education plays an important role in helping to influence attitude. It was notable, in this study that post-test, the only significant change in attitude was a decrease in the number of participants who favoured a change in the law from the current system of informed consent to one of presumed consents.
There was an increase in awareness of the benefits of organ donation but this was not significant as a high proportion of participants at baseline (87%) expressed such awareness. There was very little change, if any, with regard to associating organ donation with a hastened death (attitude 3, table 3), fear of organ misuse (attitude 4, table 3) or opinion about financial assistance (attitude 8, table 3).
Education about organ donation is not routinely incorporated in nursing degree curricula.28 A course of study needs to be objective and sufficiently informative to encourage independent thought that will lead to measured decisions to donate and can be conveyed with justification to relatives. The “Spanish Model of Organ Donation and Transplantation” has been accredited with the highest rate of deceased organ donation for a whole country.44 This model provides education to healthcare professionals, helping them to engage fully with organ donation and transplantation and has directly resulted in a continuous rise in the number of families willing to provide consent to donation.45
It needs to be recognised that while the individual decision whether or not to donate should be paramount, in many cases the final decision rests with relatives. Indeed, the most common reason for lack of organ donation is a failure to obtain consent from relatives of the potential donor.46 This is attributed to families not being made fully aware of the prior wishes of the deceased.47–49 Communicating an intention to donate to family members is frequently omitted.50 ,51 This may be the reason that over half of all families approached for organ donation in the UK typically refuse to provide consent.12 The importance of effective communication was addressed in this programme of study, with results indicating that participants were more likely to engage in discussion about organ donation with family members after the programme was completed. The programme may have directly motivated such discussions or it could be that other emotive aspects, encountered during the course of study, may have prompted such discourse.
This study has shown that even within a small group, after a programme of study, the understanding about organ donation and the processes involved can be significantly improved, leading to consideration about donation of organs and decisions with relatives. This study aimed to capture any changes in knowledge and attitudes immediately after a programme of study and to determine whether there would be a concomitant response in organ donation registration and discussion behaviours. Registration rates of the participants before starting the study were akin to those of the general population12 suggesting that choice of a caring vocation such as nursing does not necessarily equate with a greater degree of altruism with respect to organ donation. This observation that many healthcare professionals do not always exhibit prodonation behaviours has been reported previously.17–24 A considerable proportion of participants indicated that they associated registering as an organ donor with issues of mortality and this may help explain the relatively low level of donation. It has been suggested that the exhibition of unusually high levels of fear or anxiety about death can prevent people from associating themselves with a behaviour that requires them to consider their own mortality.52–54 ,55 It should also be noted that the cohort in this study was relatively young and would be less likely to have encountered life-threatening situations or serious illness. There were too few participants in the older age groups to assess any trends with age.
The concept of brain death and what constitutes the legal definition of death has been frequently misunderstood by healthcare professionals.11 ,17 ,19–22 The results show that participants’ understanding of brain death and the likelihood of recovery following a diagnosis of brain death improved significantly on completion of the study. Although this is a promising result, a small proportion of the participants, nevertheless, continued to raise concerns about their understanding of this important concept. Correctly understanding brain death and the likelihood of recovery is paramount in the organ donation process to ensure that misconceptions are avoided and that relatives of the deceased can be properly informed to make confident end-of-life decisions.47 ,56 ,57
The results demonstrate that prior to the programme of study, around one-third of the participants did not understand which organs could be successfully donated after death and this was most pertinent in relation to the donation of corneal tissue—an organ that is not donated to save life but to restore sight. The programme of study improved understanding significantly. Less than a fifth of participants were aware of the many different methods that exist to register organ donation intentions in the UK before the programme; while this improved after completion of the programme, less than half of the cohort (42%) exhibited sufficient knowledge in this area. The increase in knowledge may have had an effect on attitude, as after the programme of study a greater number of participants were unwilling to support changes to legislation and favoured the current system of informed consent. This notwithstanding, the majority (64%) of the participants supported changes to the organ donation system in the UK.
The majority of the participants in this study disapproved of a financially incentivised rewards scheme and this did not alter after the programme of study. This effect has been reported previously35 and is thought to be because financial payments appear to undermine the individual and cast doubt over their intentions to donate.58
This study used a pretest–post-test design. The limitations of such a design are that the pretest may sensitise participants to what is being investigated and thereby affect post-test results. In this research, the intervention was a programme of study aimed at informing and teaching participants and hence the post-test was to determine what had been learned and understood and how this may alter attitudes and behaviour. Given that the participants will have been aware that they would be asked to complete a questionnaire after the programme of study, they may have paid more attention to the course content, than they otherwise would have done. The short duration between the intervention and the pretesting and post-testing minimised the effects of any external factors that could have occurred between testing and the programme. However, as the programme took place over a period of 2 months, there may have been influences from media or other social or community sources that participants encountered between lectures that had some effect on the post-test results.
More insight into the benefits of such courses will be gained by investigating a wider diversity of cohorts and trialling longer courses of study so that participants have a longer period of time to consider whether to register for organ donation. As this study utilised a convenience sample to recruit participants from a single institution, the findings cannot be generalised to other nursing students from the UK.
A short programme of study can effectively improve student nurses’ knowledge of organ donation and positively influence their ability to discuss organ donation intentions with their family. The effect of education, whether concentrated and provided over a shorter period or given as a smaller component of a course emphasising various aspects of organ donation and procurement, needs to be tested with different cohorts from various parts of the UK. This will help determine whether providing appropriate education to those who will be involved in procuring organs for transplantation can influence the number and types of organs that are donated.
