Web-Based Advance Care Planning for Patients With Advanced Cancer

A Web-Based Advance Care Planning Intervention to Reduce Preferences for Aggressive Life-Sustaining Treatments in Patients With Advanced Cancer: A Randomized Controlled Trial

The goal of this clinical trial is to determine whether a web-based advance care planning (ACP) intervention can reduce preferences for aggressive life-sustaining treatments among patients with advanced cancer.

The main questions it aims to answer are:

• Does a web-based ACP intervention reduce preferences for aggressive life-sustaining treatments among patients with advanced cancer?
• Does a web-based ACP intervention support informed medical decision-making regarding future care?

Researchers will compare a web-based ACP intervention plus a Patient Right to Autonomy Act leaflet with a Patient Right to Autonomy Act leaflet alone to determine whether the web-based ACP intervention is more effective in reducing preferences for aggressive life-sustaining treatments.

Participants will:

• Be randomly assigned to either an intervention group or a control group
• Receive either a web-based ACP educational program plus a Patient Right to Autonomy Act leaflet, or a Patient Right to Autonomy Act leaflet alone
• Complete questionnaires at baseline, immediately after the intervention, and one week after the intervention

Advance care planning (ACP) is a process that enables individuals to understand and communicate their values, goals, and preferences regarding future medical care. ACP is particularly important for patients with advanced cancer, who may face complex decisions regarding life-sustaining treatments and end-of-life care. However, ACP participation remains limited, and innovative approaches are needed to improve patient engagement.

This study was designed to evaluate the effectiveness of a web-based ACP intervention in reducing preferences for aggressive life-sustaining treatments among patients with advanced cancer. The intervention was developed to provide accessible ACP education and information regarding the Patient Right to Autonomy Act in Taiwan.

A single-blind randomized controlled trial design was used. A total of 110 patients with stage III or IV cancer were recruited and randomly assigned to either an intervention group (n = 55) or a control group (n = 55). Participants in the intervention group received a web-based ACP educational program in addition to a Patient Right to Autonomy Act leaflet, whereas participants in the control group received the leaflet alone.

Outcome assessments were conducted at baseline (T1), immediately after the intervention (T2), and one week after the intervention (T3). The primary objective was to determine whether the web-based ACP intervention reduced preferences for aggressive life-sustaining treatments. The study also examined factors associated with treatment preferences and medical decision-making.

The findings of this study may contribute to the development of accessible ACP interventions and support informed decision-making among patients with advanced cancer.
