Does anatomical type of proximal hip fracture affect rehabilitation outcomes among older adults?

Abstract

Background and purposeNumerous studies have detailed the potential benefits of inpatient geriatric rehabilitation for older adults with hip fractures. However, data regarding effect of fracture type (femoral neck, intertrochanteric, or subtrochanteric) on rehabilitation outcomes are limited. This study assessed whether the anatomical type of proximal hip fracture affects rehabilitation outcomes among disabled older adults. MethodsA population-based study was conducted comparing all patients with a recent hip fracture who were admitted to a geriatric rehabilitation facility in Israel. Data were collected retrospectively from an electronic database during a 5-year period (2014–2019). The Functional Independence Measure (FIM) was used to assess physical and cognitive function at admission and discharge. ResultsThe analyses included 624 older adults with hip fractures. We found significant differences in motor FIM score at admission, as patients with femoral neck fracture performed better than patients with intertrochanteric and subtrochanteric fracture did. The disparity in motor FIM score remained consistent through discharge, with all groups achieving a median gain of 14 points. Within one month of rehabilitation, about a third of all patients achieved a higher functional level. ConclusionsPatients with femoral neck fracture have better motor ability than do those with intertrochanteric and subtrochanteric fractures, which were retained throughout the course of rehabilitation; yet, the level of improvement remained similar. Clinicians should be aware of such differences in functional ability when discussing goals of care with older adults with hip fractures and consider them when implementing individual rehabilitation programs .
