Additionally, when available, previous medical records, including cognitive evaluations, were also used to support the assessors on determining the acute change in mental status and the presence of inattention. A final consensus diagnosis was obtained by 2 geriatricians (G.B., F.G., R.T.) and 1 neuropsychologist (E.L., S.M.). Instances of disagreement between 2 geriatricians and PLX4032 concentration a neuropsychologist were resolved by consensus among the 3 geriatricians and the 2 neuropsychologists.

The primary outcome was that of walking dependence captured as a trajectory from discharge to 1-year follow-up. Degree of walking dependence at discharge and at 1-year follow-up was assessed using the BI walking mobility subitem. A score less than 15 (the maximum score) is robust to the presence of mobility impairment.30 and 31 The BI administered by telephone has been shown to be as reliable as to direct face-to-face assessment.32 This primary outcome was defined a priori. Participants were recontacted

by telephone to assess walking ability at 1-year follow-up. The interviewers this website (F.G., R.T.) asked the patient or the caregiver to indicate the most accurate description of the participant’s functional status after reading all possible answers for the BI walking subscore. Nursing home placement and mortality were ascertained through telephone interview with family members at 1 year after the discharge. Demographics and clinical variables were summarized using median and interquartile range (IQR) for continuous variables

or proportions for categorical variables. The independent associations between cognitive diagnosis (none, dementia, delirium, DSD) (exposure) and walking dependency at discharge and at 12 months (outcomes) were estimated using random-effects logistic regression models, with a random effect for intercepts and slopes. Specifically, dementia, delirium, and DSD were MycoClean Mycoplasma Removal Kit compared with the reference group (no delirium and no dementia.) Such a model allows accounts for the longitudinal effects of cognitive diagnosis on the outcome; that is, how delirium and/or dementia influence general walking dependency at discharge and the change 1 year later. Models were adjusted by age, sex, length of stay, preadmission walking impairment, place of care before admission, C-reactive protein, and CCI.33 These last 2 variables were transformed to accommodate the degree of positive skew. These variables were selected a priori according to their potential clinical relevance on the outcomes. In this model, patients who died in the year following discharge were excluded. Two additional logistic regression models were used to estimate the association between cognitive diagnosis (none, dementia, delirium, DSD) and nursing home (NH) placement and mortality at 1-year follow-up. Models were adjusted for the same covariates of the random-effects logistic regression models.
