Risk Factors for Falls in Individuals With Lower Extremity Amputations During the Pre-Prosthetic Phase: A...

Falls in individuals with lower limb amputations (LLAs) pose significant health concerns. The literature is limited regarding falls during the preprosthetic phase of rehabilitation for persons with LLAs.

To determine the incidence of falls and identify factors associated with falls during the preprosthetic recovery phase.

Retrospective chart audit.

Inpatient rehabilitation program.

Four hundred forty individuals with LLAs (age ± SD = 61.93 ± 14.53 years, 73.18% male) who attended inpatient rehabilitation from 26 July 2011 to 21 August 2017.

Not applicable.

The number of self-reported falls was recorded from the time of surgery to admission for inpatient rehabilitation. Outcomes of interest were any fall (1+ fall) and recurrent falls (2+ falls). A retrospective chart audit was performed on consecutive admissions to an inpatient rehabilitation program.

The incidence of falls was 8.37 per 1000 patient-days. Falls were sustained by 60.9% of the sample. Unilateral transtibial amputation was independently associated with an increased risk of recurrent falls (relative risk [RR] 1.59, 95% confidence interval [CI] 1.13-2.23, P = .008). Diabetes mellitus was independently associated with an increased risk of any fall (RR 1.18, 95% CI 1.01-.38, P = .03). Finally, bilateral transtibial amputation was independently associated with a reduced risk of any fall (RR 0.59, 95% CI 0.39-0.90, P = .014).

Consistent with the current literature, diabetes mellitus and a unilateral transtibial amputation were risk factors for falling, whereas a bilateral transtibial amputation and increasing age presented new findings as factors associated with decreased falling.
