Acceptance, Awareness, Attitude, and Practices Toward Heart Transplantation: A Saudi Based Survey

The awareness of brain death and heart donation (HD) among the Saudi population remains limited, coupled with negative attitudes toward heart donation, resulting in a significant gap between the demand for donor hearts and the available supply. This study aimed to comprehensively understand the current perceptions, attitudes, and practices of the Saudi population regarding HD, as well as identify the obstacles. The ultimate goal was to strengthen the local donor pool.

A cross-sectional study was conducted from March to May 2023, employing a self-administered internet survey. The survey collected demographic information, assessed awareness, attitudes, and practices related to HD, and was completed by 1820 participants from various regions in Saudi Arabia. Data was analyzed using SPSS version 25 (SPSS Inc., Chicago, Illinois, USA). Chi-square test, Independent-samples t-test, one way analysis of variance test (ANOVA) and Spearman correlation coefficient was performed with the significance level set at p < 0.05.

A significant portion of the population (out of 1820 participants) lacked organ donation cards and were uncertain about the registration process. Participants displayed a moderate level of knowledge about HD, with roughly half holding unfavorable attitudes toward HD. A considerable percentage of participants 62.0% were unwilling to register as heart donors, but a majority (79.9%) were willing to contribute by disseminating information about HD. The study identified significant associations between knowledge scores and several factors, including age (p = 0.002), career (p = 0.000), possession of an organ donation card (p = 0.000), and a history of transplantation or organ donation among relatives (p = 0.000). A significant relationship was observed between attitude scores and several factors, including career (p = 0.001), Saudi region (p = 0.025), possession of an organ donation card (p = 0.000), and a history of transplantation or organ donation among relatives (p = 0.000).

The study highlights the urgent need for increased awareness to bolster the number of local heart donors. The involvement of healthcare professionals and social campaigns is essential to enhance public knowledge and potentially boost the willingness of individuals to become donors.
