Association between multidimensional prognostic index (MPI) and pre-operative delirium in older patients with hip fracture.

Pre-operative delirium may cause delay in surgical intervention in older patients hospitalized for hip fracture. Also it has been associated with higher risk of post-surgical complications and worst functional outcomes. Aim of this retrospective cohort study was to evaluate whether the multidimensional prognostic index (MPI) at hospital admission was associated with pre-operative delirium in older individuals with hip fracture who are deemed to require surgical intervention. Consecutive older patients (≥ 65 years) with hip fracture underwent a comprehensive geriatric assessment to calculate the MPI at hospital admission. According to previously established cut-offs, MPI was expressed in three grades, i.e. MPI-1 (low-risk), MPI-2 (moderate-risk) and MPI-3 (high risk of mortality). Pre-operative delirium was assessed using the four 'A's Test. Out of 244 older patients who underwent surgery for hip fracture, 104 subjects (43%) received a diagnosis of delirium. Overall, the incidence of delirium before surgery was significantly higher in patients with more severe MPI score at admission. Higher MPI grade (MPI-3) was independently associated with higher risk of pre-operative delirium (OR 2.45, CI 1.21-4.96). Therefore, the MPI at hospital admission might help in early identification of older patients with hip fracture at risk for pre-operative delirium.

Frailty is associated with socioeconomic and lifestyle factors in community-dwelling older subjects.

BACKGROUND AND AIMS: This study assessed the association between frailty and sociodemographic, socioeconomic and lifestyle factors in community-dwelling older people. METHODS: This was a cross-sectional survey in a population-based sample of 542 community-dwelling subjects aged 65 years and older living in a metropolitan area in Italy. Frailty was evaluated by means of the FRAIL scale proposed by the International Association of Nutrition and Aging. Basal and instrumental activities of daily living (ADL, IADL), physical activity, sociodemographic (age, gender, marital status and cohabitation), socioeconomic (education, economic conditions and occupational status) and lifestyle domains (cultural and technological fruition and social activation) were assessed through specific validated tools. Statistical analysis was performed through multinomial logistic regression. RESULTS: Impairments in ADL and IADL were significantly associated with frailty, while moderate and high physical activity were inversely associated with frailty. Moreover, regarding both socioeconomic variables and lifestyle factors, more disadvantaged socioeconomic conditions and low levels of cultural fruition were significantly associated with frailty. CONCLUSIONS: Socioeconomic and lifestyle factors, particularly cultural fruition, are associated with frailty independently from functional impairment and low physical activity. Cultural habits may therefore represent a new target of multimodal interventions against geriatric frailty.
