Instability of Willingness to Accept Life-Sustaining Treatments in Patients With Advanced Chronic Organ Failure During 1 Year

Background: For optimal end-of-life decision-making, it is important to understand the stability of patients' treatment preferences. The aim of this paper is to examine the stability of willingness to accept life-sustaining treatments during 1-year follow-up in Dutch patients with advanced chronic organ failure. In addition, we want to explore the association between willingness to accept high-burden treatment and preferences for CPR and mechanical ventilation (MV).

Methods: In this multicenter longitudinal study, 265 clinically stable outpatients with advanced COPD (Global Initiative for Chronic Obstructive Lung Disease stage III/IV [n = 105]), chronic heart failure (New York Heart Association class III/IV [n = 80]), or chronic renal failure (requiring dialysis [n = 80) were visited at baseline and at 4, 8, and 12 months to assess the stability of life-sustaining treatment preferences using the Willingness to Accept Life-sustaining Treatment instrument.

Results: Two hundred six patients completed 1-year follow-up (mean age, 67.2 years [SD, 13.1 years]; 64.1% men). Overall, proportions of patients who were willing to accept life-sustaining treatment during 1 year did not change over time. However, individual trajectories showed that about two-thirds of patients changed their preferences at least once during a year. Moreover, there was no association found between the stability of willingness to undergo high-burden therapy and the stability of preferences for CPR and MV.

Conclusions: The current findings show the complexity of preferences for end-of-life care and indicate once again that advance care planning is a continuous process between patients and physicians, in which preferences for specific situations are discussed and that needs to be regularly reevaluated to deliver high-quality end-of-life care.
