  • Prevalence of impairment. If necessary for comparison, the combined prevalence of two separate categories is shown (e.g., severely dependent and dependent for ADLs). Of all of the studies that applied a systematic assessment, the scale and cutoff values are reported. BDI, Beck Depression Inventory, S, applied by staff; P, patient self-report; ICD, International Statistical Classification of Diseases; R, review of medical chart; x, analysis includes elderly patients exclusively; MHI SF-36, Mental Health Inventory Short Form 36; ADL, activity of daily living; SGA, Subjective Global Assessment; A, well nourished; B, mild-moderately malnourished; C, severely malnourished; —, not mentioned; AGGIR, Autonomie Gérontologique Groupes Iso-Ressources; WHO, World Health Organization.
