Context: Previous work has found that facilitated advance care planning (ACP) interventions are effective in increasing ACP uptake among patients with severe respiratory disease. Objectives: The objective of this study was to investigate whether a nurse-led, facilitated ACP intervention among participants with severe respiratory disease impacts self-reported or clinical outcomes. Methods: A multicenter, open-label, patient-preference, randomized controlled trial of a nurse-led facilitated ACP intervention was performed. Outcome measures included self-report scales (health care satisfaction and EQ-5D-5L health-related quality of life at three- and six-month follow-up), 12-month mortality, and health care utilization during the final 90 days of life. Results: One hundred forty-nine participants were recruited across two study settings (metropolitan tertiary hospital respiratory department and rural sites) and 106 were allocated to receive the ACP intervention. There was no effect of the intervention on satisfaction with health care, health-related quality of life, or 12-month mortality rates. Among those participants who died during the follow-up period (N = 54), those allocated to the ACP intervention had significantly fewer outpatient consultations (7.51 vs. 13.6, P < 0.001). There were no changes in emergency department attendances, total hospital admissions or length of stay, or home nursing visits. Among those allocated to the ACP intervention, there was a reduced length of stay in acute hospital settings (7.76 vs. 11.5 nights, P < 0.001) and increased length of stay in palliative hospital settings (5.54 vs. 2.08, P < 0.001) during the final 90 days of life. Conclusion: A facilitated ACP intervention among patients with severe respiratory disease did not have an impact on satisfaction, health-related quality of life, or 12-month mortality rate. Facilitated ACP may be associated with a different type of health care utilization during the end-of-life period.
