“…Conversely, nonvalidated tools were used to measure alertness and confusion and subjective methods used to assess muscle strength; any resulting misclassification bias involving these ordinal variables may have resulted in an away from the null bias, i.e., suggesting an association between the variable and falls where none exists. 18 In the study by Pautex et al, 33 the charts of all patients with advanced cancer hospitalised over a one year period were reviewed and the characteristics of those who fell during admission compared to those who did not. In addition to those variables shown to be associated with falls, as per Table 2, the following variables were examined; demographic details, Charlson Comorbidity Index, main medical diagnoses, Mini-Mental State Examination (MMSE), functional independence measure, incident comorbidities, hemoglobin concentration, administration of opioid, benzodiazepine, neuroleptic, antiepileptic, antidepressant, hypotensive, diuretic, respiratory system, corticosteroid and antibiotic med- ications, use of parenteral hydration or nutrition, and administration of palliative sedation.…”
