title: Falls sustained during inpatient rehabilitation after lower limb amputation: prevalence and predictors.
abstract: OBJECTIVE
  The purpose of this study is to identify risk factors for falling and fall-related injury among a group of inpatients undergoing rehabilitation after major lower limb amputation.
  
  
  METHODS
  Retrospective cohort.
  
  
  RESULTS
  Out of 1267 patients, 260 (20.5%) fell at least once. There were a total of 374 falls, 67 (17.9%) of which resulted in one or more injuries. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated for factors significantly associated with falling, including age of > or =71 yrs (OR = 1.40, 95% CI = 1.02-1.89), lengths of stay of 22-35 days (OR = 2.97, 95% CI = 1.14-7.72) or >5 wks (OR = 6.07, 95% CI = 2.34-15.71), four or more comorbidities (OR = 1.93, 95% CI = 1.09-3.41), cognitive impairment (OR = 1.68, 95% CI = 1.02-2.78), two or more as-needed medications (OR = 1.81, 95% CI = 1.02-3.21), benzodiazepines (OR = 2.22, 95% CI = 1.24-3.96), and opiates (OR = 5.76, 95% CI = 3.29-10.09). Factors significantly associated with fall-related injuries included bilateral amputation (OR = 3.68, 95% CI = 1.49-9.05) and falls during the day shift (OR = 2.63, 95% CI = 1.24-5.57).
  
  
  CONCLUSIONS
  One in five patients with lower limb amputation will likely experience at least one fall during inpatient rehabilitation, with 18% sustaining an injury. Ongoing research is required to develop appropriate intervention strategies to ameliorate the risk of falling during inpatient rehabilitation.
