Implementation, participation and satisfaction rates of a web-based decision support tool for patients with metastatic colorectal cancer

Objective: To examine implementation and patients' and providers' participation and satisfaction of a newly developed decision support tool (DST) for patients with metastatic colorectal cancer (mCRC) in palliative setting.Methods: Our DST consisted of a consultation sheet and web-based tailored information for mCRC treatment options. We conducted an implementation trajectory in 11 Dutch hospitals and evaluated implementation, participation and satisfaction rates.Results: Implementation rates fluctuated between 3 and 72 handed out (median:23) consultation sheets per hospital with patients' login rates between 36% and 83% (median:57%). The majority of patients (68%) had (intermediate)-high participation scores. The median time spent using the DST was 38 min (IQR:18-56) and was highest for questions concerning patients' perspective (5 min). Seventy-six% of patients were (very) satisfied. The provider DST rating was 7.8 (scale 1-10) and participation ranged between 25 and 100%. Remaining implementation thresholds included providers' treatment preferences, resistance against shared decision-making and (over)confidence in shared decision-making concepts already in use.Conclusion: We implemented a DST with sufficient patient and oncologist satisfaction and high patient participation, but participation differed considerably between hospitals suggesting unequal adoption of our tool.Practice implications: Requirements for structural implementation are to overcome remaining thresholds and increase awareness for additional decision support.
