Background & Aim: Although the number of kidney donors is increasing in the country, few relatives decide to donate. Decision making on kidney donation to a relative faces many challenges, while how to make this decision is still ambiguous. The aim of the present study was to explore the way of decision making about kidney donation to a relative.
Methods & Materials: The present study was a qualitative study conducted in 2015. The thematic analysis approach was used to analyze the data. In this study, 16 relative donors from the kidney transplant centers of all the teaching hospitals affiliated to Tehran University of Medical Sciences (Imam Khomaini, Shariati, Sina) were selected through purposive sampling. Then, 16 face-to-face, in-depth, semi-structured interviews were conducted. Data were analyzed using the thematic analysis approach proposed by Clark & Braun (2006).
Results: Data analysis led to the identification of two themes “being resolute in decision making” and “mulling over the decision”. The first theme was comprised of three subthemes including donation with a heartfelt desire, consistency in decision making, discretion in decision making, and the second theme was consisted of two subthemes including unsteady in decision making and bargaining in decision making.
Conclusion: Decision making on kidney donation to a relative faces a variety of challenges influenced by the donor’s family background, the supportive role of family members, kinship ties and a sense of love for relatives. By providing knowledge and awareness to donors to address ambiguities and subjective questions, they can have an important role in developing the culture of relative’s kidney donation.
