Frailty is associated with pain and cognitive function in older people in post-acute care settings

To describe pain, cognitive function, and frailty of older people in post-acute care settings and examine the association between the three elements. This cross-sectional study involved 142 participants from a rehabilitation ward and a geriatric day centre. Pain, cognitive function and frailty were assessed using Brief Pain Inventory, Abbreviated Mental Test, and 5-item Frail Scale respectively. Participants were mostly women (51.7%) with a mean age of 76.5 (SD 7.8). Mean scores for pain, cognition, and frailty were 9.0 ± 1.0, 4.0 ± 2.8, and 2.2 ± 1.2, respectively. Cognition had a significant inverse association with frailty (β = −0.160, p = 0.047), and pain had a significant positive association with frailty (β = 5.122, p
