Functional outcomes in geriatric patients with spinal cord injuries at a tertiary care rehabilitation hospital in Saudi Arabia

Abstract

Study design: Retrospective study.

Objective: To identify demographic features, clinical characteristics, and complications associated with spinal cord injuries/disorders (SCI/D) among elderly individuals at a rehabilitation hospital and to measure the functional outcomes of rehabilitation.

Setting: Rehabilitation hospital in King Fahad Medical City (KFMC), Riyadh, Saudi Arabia.

Methods: The study was conducted in elderly individuals (aged ≥65 years) with SCI/D, admitted to an inpatient rehabilitation program between October 2014 and 2015. Demographic and clinical data were recorded along with functional independence measure (FIM) score at admission (FIMa) and discharge (FIMd). Data were descriptively analyzed. Association of non-metric and metric variables with complications was measured using χ², and Student's t-test, respectively.

Results: Twenty-four individuals with SCI/D (95.8% were male and retired) with mean (standard deviation, SD) age of 72.3 (6.3) years were included. The most common co-morbidities were hypertension (75.0%), and diabetes mellitus (58.3%). Degenerative cervical myelopathy (33.3%) was the most common cause of SCD. Of all, nine (37.5%) individuals had clinical complications (urinary tract infection(UTI); 8/9, surgical wound infection; 1/9). Mean (SD) hospitalization period during inpatient rehabilitation was 66.0 (13.9) days. Mean (SD) FIMa scores improved from 71.7 (17.3) to 85.3 (16.8) at discharge. Co-morbidities associated with complications were peripheral vascular disease, ischemic heart disease, and stroke.

Conclusion: In Saudi Arabia, non-traumatic spinal etiologies are the most frequent cause of spinal cord dysfunction in the elderly. Male gender, hypertension, and diabetes mellitus were high-risk factors among the geriatric age group with SCI/D. Elderly individuals with SCI/D without complications can have a shorter hospitalization period and higher functional gains during rehabilitation.
