BackgroundAdults with congenital heart disease (ACHD) are growing in number and living longer with complex lesions; however, many are at risk of death in mid-life. Conversations about advance care planning (ACP) in this population have been found to be infrequent and not part of regular outpatient care. The intent of this study was to explore ACHD patients’ readiness to discuss ACP and assess the impact of interventions to support ACP conversations. MethodsWe conducted a prospective, randomized, single-center trial of adults with moderate to severe CHD. Simply, the control group was asked if they were ready to discuss their wishes if they were to become seriously ill. The intervention group was provided two additional resources with the readiness question, the modified Lyon Family-Centered ACP Survey (ML-ACP) and a patient-partner created ACHD-ACP video. ResultsA total of 111 responses (control (n=59) and intervention group (n=52)) were collected for analysis. Women represented 59.0% of the participants. The mean age was 39.6 years (SD=14.8). No significant difference was found between the control and experimental groups’ readiness (94.9% and 90.4%, respectively). Most participants (92.8%) responded positively towards initiating conversations related to end-of-life and ACP discussions. ConclusionWe found that adults with CHD are ready to have ACP conversations as part of their outpatient care. Patient preferences and values should guide ACP conversations, further research is needed to determine if the ML-ACP survey and ACHD-ACP video are helpful adjuncts for ACP in outpatient clinics.
