Improving Personalized Treatment in Oncology: Effects of Integrated Oncological Decision-making

The research aims to evaluate an Integrated Oncological Decision-making Model (IODM) to tailor oncological treatment plans to individual patients. The primary objective is to assess the impact of the IODM on personalized decision-making and patient outcomes. The study will employ a stepped-wedge cluster randomized trial design involving eight oncological care paths across four medical centers in the Netherlands. The study population consists of 400 adult patients (50 per care path) who will undergo treatment based on either standard clinical guidelines (control) or the IODM (intervention). The intervention involves integrating three key components: oncological treatment options, patient's general health status, and patient's goals and preferences. The main study parameters include measuring the discordance between recommendations based on medical information and final treatment decisions, assessing whether discordance reflects more personalized decision-making, and evaluating the implementation process of the IODM.
