Geriatric Assessment Tools. We adopted a geriatric assessment based on four domains (a-d). A domain has been judged impaired when at least one of the tools that were used to evaluated it gave a positive result (i.e. the patient had positive PEW test than the nutritional domain was impaired). The cut-offs adopted to define the positivity of the single test are reported in the methods section. Multidomain impairment was defined by altered tests in more than one domain (i.e. having an impairment in 2 domains meant having a positive test in A plus B)
