PROMIS scores in operative metastatic bone disease patients: A multicenter, prospective study.

BackgroundThe prevalence of metastatic bone disease (MBD) grows each year as treatments improve. Little has been published about functional and pain outcomes in this group after surgery. Patient-Reported Outcomes Measurement Information System (PROMIS (R)) can collect information, in just minutes, about patient's physical, mental, and social health. This study evaluated PROMIS (R) pain and functional scores in surgically treated patients with MBD. MethodsBasic demographics and PROMIS (R) scores were recorded from a total of 13 patients at 9 periods of time over 6 months. ResultsThe average change in physical function at week 1 was -2.5 (standard deviation [SD]=5.4), at 2 weeks 1.7 (SD=7.6), after 4 weeks 6.9 (SD=10), after 6 weeks 6.4 (SD=10.9), after 10 weeks 15.3 (SD=3.1), and after 3 months 8.6 (SD=7.6). The average change in pain inference at week 1 was -1.2 (SD=7.3), at 2 weeks -2.1 (SD=9.5), after 4 weeks -12.6 (SD=4.5), after 6 weeks -8.3 (SD=10.2), after 10 weeks -16.6 (SD=4.3), and after 3 months -11.4 (SD=8.2). ConclusionsPROMIS((R)) provides a feasible means to collect data in this population. Trends of improved function and decreased pain were seen after surgery. Continuing this study will hopefully elucidate more insight into the surgical treatment of MBD.
