Systems Forces Leading to Feeding Tube Placement in Patients with Advanced Dementia: A Qualitative Exploration of Clinical Momentum

Older adults with serious illness near the end-of-life often receive invasive treatments. We developed a conceptual model called clinical momentum that describes system-level forces producing a trajectory of care that is difficult to modify and contributes to overtreatment. We sought to evaluate the empirical fit of our model by examining an event with clear guidelines against intervention: permanent feeding tube placement in patients with advanced dementia.
