Objective: Hip fracture usually affects psychological functions of the elderly, and comorbidities often interfere with their recovery. However, little is known about the influence of number of comorbidities on their psychological outcomes.
Method: Data from a previous study of 461 hip-fractured elders treated at a medical center in northern Taiwan were analyzed by the generalized estimating equation approach. Outcomes were assessed at 1, 3, 6, 12 months following discharge by the Geriatric Depression Scale (GDS), Mini-Mental State Examination, and two subscales of the Medical Outcomes Study Short Form 36: role limitations due to emotional problems, and Mental Health (MH).
Results: Hip-fractured elders with more comorbidities were more likely to have cognitive impairment (β = 0.224, p = .004), higher GDS scores (β = 0.328, p = .001), and worse MH (β = -1.784, p = .009) during the first year following discharge.
Discussion: Having more comorbidities negatively influenced the psychological outcomes of elderly patients with hip fracture.
