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.Clinical Trial registration
