Paper text:
during the past decades , organ transplantation has increased and become widespread.13 it is a form of treatment that is indispensable for certain diseases and the results in terms of life years gained and improvement in quality of life are often positive .
the issue of organ donation is complex and multifactorial , involving ethical , legal , medical , organizational , and societal factors.379 healthcare professionals knowledge , attitudes , and behaviors are essential factors in fostering an environment that positively influences organ donation rates.1012 the objective of the current study was to evaluate medical students existing level of knowledge , attitudes , observations , and proposals towards organ donation .
the aristotle university of thessaloniki is the largest university in greece that provides undergraduate medical training .
the 6-year undergraduate medical curriculum focuses on the study of basic medical science in the first 3 years and on clinical rotations in the following 3 years . between june 8 and june 10 2010 ,
anonymous self - administered questionnaires were distributed to the medical students from years 1 to 6 ( n = 600 ) before morning lectures . the forms were collected immediately when the respective sessions finished .
the questionnaires consisted of 8 questions , mostly in the form of multiple choice questions , where some of them included personal suggestions ( table 1 ) .
a number of 558 valid questionnaires were filled in by 292 ( 52.3% ) male and 266 ( 47.7% ) female students , whereas 262 ( 47% ) of them were students in preclinics and 296 ( 53% ) were students in the clinics .
all statistics were carried out using the statistical package for the social sciences ( spss , version 14.0 , chicago , il ) and microsoft excel ( redmond , wa .
respondents from the preclinics comprised 45.8% of the study sample , while the respondents of clinical studies a 54.2% of the sample ( p < 0.05 ) .
65.6% of them were men and 34.7% women , whereas 59.4% were preclinical students and 40.6% clinical medical students .
the vast majority of respondents ( 78.9% ) were not aware of the current legislation concerning transplantations and organ donation in greece .
25.7% of male students and 16.2% of female students ( p < 0.005 ) seemed to have knowledge of the current legislation , where 23.3% of them were students in the preclinics and 19.3% in the clinics ( p > 0.05 ) .
moreover , only 4.2% of students had a deep knowledge of the current legislation , while 16.1% had some idea .
81.2% students suggested that a change in legislation , whereby organs can be used for transplantation after death , would cause strong societal reactions .
male students ( 52.1% ) were more likely than female students to agree with it , while there were not significant differences between students in the clinics and preclinics ( p > 0.05 ) .
nevertheless , it is important to note that 8.6% students strongly supported a change in legislation , while 10.2% of them did not give an answer .
most of them were students in the clinics ( 72 ) , while 44 of them were in preclinics .
moreover there was a slight difference among male ( 59 ) and female ( 57 ) students ( p < 0.05 ) .
many students ( 34.4% ) expressed the opinion that insufficient promotion of and information pertaining to organ donation was made available to the general public , by hellenic national transplant organization and relevant non governmental organizations .
a small minority of participants ( 5% ) opined that the hellenic national transplant organization and non governmental organizations had provided excellent information to the public ( table 2 ) .
distribution of responses to the question regarding sufficiency of promotion and information concerning organ donation made by hellenic national transplant organization and relevant non governmental organizations by sex and semester of study the main causes responsible for the shortage of transplants in our country were stated to be the inadequate public information , the greek mentality , and the lack of organized transplant centers ( table 3 ) .
there was no significant difference among male and female students , regarding inadequate information as the main reason for transplant shortage ( p > 0.05 ) .
distribution of responses to the question regarding shortage of transplants in greece , by sex and semester of study many participants ( 59.5% ) felt that public information through media ( tv , radio , conferences , and leaflets ) was the most effective way to draw public attention to the issue . some participants ( 30.5% ) suggested that a lifelong free health check - up for organ donors would increase opportunities for organ donation .
a few students ( 26.7% ) urged that voluntary organizations to exert more effort in scaling up organ donation promotion .
clinical medical students supported that public information through media ( p > 0.05 ) and lifelong free health check - up for organ donors ( p < 0.05 ) , as actions , can contribute to public awareness .
male students expressed the view that voluntary organizations increase public awareness of the critical need for organ donation ( p > 0.05 ) .
in the present study , we assessed attitudes toward tissue and organ donation with the objective of aiding policy development to increase transplantations in greece . other studies of medical students in different countries have shown a similar trend , where the proportion demonstrating accurate knowledge about donation cards was significantly increased after education.13 having chosen students with medical background for the present study may have influenced the overall donation readiness toward a more positive attitude compared to the basic population . in this study ,
this suggests a desire on the part of students to learn more about donation , as well as an opportunity for medical schools to positively impact organ donation and transplantation by educating future physicians about this important aspect of medicine.381415 health care professionals can serve as role models for patients and their relatives , and a higher success rate for organ procurement might be reached.16 other studies showed that patients have a more 
positive attitude towards organ donation if they know that their doctors are willing to donate organs.17 data from this study also emphasize that 21.1% of students had a deep knowledge of the current legislation concerning transplantations and organ donation in greece .
therefore , it might have been expected that if there was a more proper and concise legislation , there would also be a greater willingness to donate , among medical students.6715 medical students from other countries had similar problems with a relative lack of knowledge in medical law,18 brain death,1920 suitable candidates for organ transplantations , potential recipients , and the logistics of organ donation.2122 possible reasons for this matter included insufficient emphasis on organ donor recruitment in the curriculum , lack of exposure and understanding about the entire transplantation process , and paucity of any large - scale organ donation public awareness campaigns in the community .
thereafter , issues related to donor recruitment as well as supply and demand of cadaveric organs should be more emphasized in the medical curriculum . a special elective course for medical students covering aspects of organ donation might be rather helpful.781423 moreover , our results surprisingly indicated that ( 81.2% ) students believe that a change in legislation , whereby organs can be used for transplantation after death , will cause strong societal reactions .
this issue must be considered real and needs to be carefully addressed . in that way ,
when medical students asked about organ donation campaign of hellenic national transplant organization strategies to promote organ donation , the lack of a promotion and awareness campaign was again brought up by the participants.5 they felt that if organ donation is a commonly occurring action , more people would be willing to donate their organs.23 our results indicated that most of the students considered insufficient the information provided by hellenic national transplant organization and relevant authorities .
students believed that information provided to general public used a scientific oriented terminology , while most time was not renewed .
it is thus important to recognize the pronounced societal and educational differences in values , attitudes , and beliefs with respect to organ donation.1124 the above mentioned issues have a negative impact to medical students attitudes toward organ donation .
therefore , the main cause responsible for the shortage of transplants in our country was stated to be the inadequate public information .
although , greek mentality was the second cause in our study ; greeks in general are sensitive in medical issues but unwilling to promote organ donation .
the third reason for shortage of transplants in our country was the lack of organized transplant centers .
this is not true since many centers of excellence have been established in recent years.5 our study identified that the principle respondents source of information about organ donation was media .
general studies had also shown the importance of media in increasing public awareness,1341014 the lifelong free health check - up for organ donors that has been proposed is quite difficult to be implemented in greece .
voluntary organizations that promote organ donation had been the third action proposed by medical students .
volunteer organizations may provide dynamic educational and outreach programs and services to the general public . as a consequence
this demand can be alleviated by encouraging people to donate organs through efforts from relevant authorities .
the undergraduate medical curriculum should include courses on organ transplantation to better equip future doctors with knowledge on organ donation issues .
coordinated initiatives including information , education campaigns , and knowledge are of great importance for opening a modern public debate . negative or ambivalent attitudes and lack of knowledge and trust in health care systems should be abandoned since potentially can cost lives .
objectives : in greece , there is limited research on issues related to organ donation . 
 we aimed to study the attitudes , knowledge , and actions of local medical students regard to organ donation and transplantations of tissues and organs in greece.methods:this cross - sectional questionnaire based survey was done in laboratory of hygiene and social medicine , school of medicine , aristotle university of thessaloniki , greece on medical students in years 1 to 6 . in a sample of 600 medical students , a special anonymous questionnaire , which included data as sex , age , and semester of studies , as well as questions regarding certain aspects of transplantation , was distributed . 
 558 valid questionnaires were completed ( men 52.3% and women 47.7%).results : the vast majority of the sample ( 93.6% ) were in favor of transplantations whereas 32 ( 5.7% ) of the students claimed to be organ donors . 
 78.9% claimed ignorance of the existing legislation concerning transplantations and organ donation in our country . 
 81.2% believed that the voting of law , which would consider all greek organ donors after death will cause strong reactions . 
 as the main causes , responsible for the shortage of transplants in our country were stated to be the inadequate public information , greek mentality , and the lack of organized transplant centers . 
 public information through media , a lifelong free health check - up for organ donors and activation of voluntary organizations that promote organ donation were proposed as the most important actions that could increase organ donation and transplantations in greece.conclusions:the need for further informative actions stressing the importance of organ donations appears to be the only way to increase transplantations in our country and towards this direction medical students could also be activated . 
 a new medical curriculum should increase medical students awareness of the organ shortage problem . 
 public education is recommended to correct misconceptions .
