title: Medication use is associated with fatigue in a sample of community-living individuals who have a spinal cord injury: a chart review.
abstract: OBJECTIVE
  To investigate the relationship between medications known to cause fatigue in spinal cord injury (SCI) and fatigue severity and to describe the pattern of prescription of these medications.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  GF Strong Rehabilitation Centre, Vancouver, British Columbia, Canada.
  
  
  METHODS
  Medical charts of 136 individuals admitted to the GF Strong Outpatient SCI Program between December 2004 and May 2007 were reviewed. Data collected included information on medications, clinical and demographic characteristics and Fatigue Severity Scale (FSS) scores. Multiple linear regression techniques were used to analyse the data.
  
  
  RESULTS
  Fifty-two percent of the subjects had clinically relevant fatigue. As a group, the subjects were taking 147 different medications; 41/147 medications were identified as causing fatigue. The two most commonly prescribed categories of medications were antispasticity medications (75 subjects) and analgesic medications (61 subjects). Although several variables were found to contribute to the FSS scores including the use of fatigue-causing medications, the presence of pain (7.6% of variance) and the use of fatigue-causing analgesics (4.2% of variance) explained the most variance in the scores.
  
  
  CONCLUSIONS
  Fatigue is prevalent in outpatients with SCI. Fatigue-causing medications contribute to a higher FSS score. Clinicians treating persons with SCI should be aware that fatigue is a common and significant problem. Clinicians should be aware that fatigue may be exacerbated by the use of medication and should enquire about the effects of medication on fatigue when assessing and prescribing new medications.
