“…Living with MM compared with having a single condition is associated with numerous negative outcomes for older adults: reduced life expectancy, avoidable hospitalizations; lower quality of life; poorer mood; frailty; increased risk of development of cognitive impairment; disability; functional decline; problems with medication use; and treatment conflicts (Bayliss et al., ; Ekdahl et al., ; Gilbert et al., ; Le Reste et al., ; Marengoni et al., ; Martin et al., ; Melis, Marengoni, Angleman, & Fratiglioni, ; Menotti et al., ; St John, Tyas, Menec, & Tate, ; Vassilaki et al., ; Woo & Leung, ). These multiple and interacting negative outcomes for older adults with MM challenge the healthcare system to provide care while containing costs (Bayliss, Edwards, Steiner, & Main, ; Boyd et al., ; Ekdahl et al., ; Gilbert et al., ; Gill et al., ; Hansen, Pohontsch, van den Bussche, Scherer, & Shäfer, ; Wilson, Gauvin, & Lavis, ).…”
