Cognitive and non-cognitive factors affecting decision-making about deceased organ donation in Italy: a systematic review

INTRODUCTION: Decision -making about organ donation (OD) is influenced by interrelated cognitive and non -cognitive factors. The identification of these factors in the general population and among healthcare professionals (HCP) in Italy are key ethical and scientific requirements to inform targeted communication and policy -making interventions, and to promote decision -making processes that are truly informed. EVIDENCE ACQUISITION: A systematic review of articles published between January 1, 1999, and January 31, 2024 was performed by searching four databases using these terms: "organ donation" AND (attitude OR opinion OR knowledge OR awareness OR intention OR beliefs OR norms OR perception) AND (Italy OR Italian). The reference sections of included articles were scrutinized for additional references. EVIDENCE SYNTHESIS: Most respondents (lay citizens and HCPs) were in favor of OD, but many (mainly but not exclusively lay citizens) would not authorize OD in the event of death of a family member. Lack of knowledge about OD and the gap between demand and supply of organs, fear of body mutilation, doubts about the criteria for brain death diagnosis, doubts about the wishes of the deceased family member, and distrust towards medical doctors and the healthcare system were the most commonly reported reasons, confirming that cognitive and non -cognitive factors are at play. CONCLUSIONS: The majority of the Italian population supports OD, but cognitive and non -cognitive barriers are present even among HCPs. Communication campaigns, encouraging family discussions about OD, providing better education for HCPs (including medical and nursing students), and making it easier to sign OD cards may promote informed decision -making and possibly increase consent rates.
