The critical need to implement and utilize patient-reported measures of function in cancer care delivery

The study by Smith et al. on the Patient-Reported Outcomes Measurement Information System (PROMIS) Cancer Function Brief 3D Profile shows that it can be used to measure how an individual functions and how his or her function changes during cancer treatments. This is important because most patients will experience a decline in function during cancer treatment and will struggle to fully participate in their life roles. Strong evidence demonstrates that rehabilitation improves function for individuals with cancer; rehabilitation is relatively underutilized. We suggest that using the PROMIS tool as a repeated measure throughout cancer treatment will help to identify those with functional decline who will benefit most from rehabilitation.
