title: Reliability of the spine adverse events severity system (SAVES) for individuals with traumatic spinal cord injury.
abstract: METHODS
  Test-retest analysis.
  
  
  OBJECTIVE
  To determine the intra- and inter-rater reliability of the Spine Adverse Events Severity System for Spinal Cord Injury (SAVES-SCI) in patients with traumatic SCI.
  
  
  METHODS
  Quaternary care spine program in Vancouver, Canada.
  
  
  METHODS
  Ten hypothetical patient cases were developed. The cases were completed by 10 raters (seven physicians, one nurse, one physiotherapist and one researcher) who were asked to identify and grade the severity of adverse events using SAVES-SCI twice with 1-week interval. Intra- and inter-rater reliability were calculated using kappa statistics and intraclass correlation coefficients (ICC).
  
  
  RESULTS
  Intra-rater reliability for both identifying and grading AEs were high with all AEs (kappa greater than 0.6) except for bone implant, diathermy burn, massive blood loss, myocardial infarction, neurological deterioration, pressure ulcer, return to operating room and tracheostomy requirement. The inter-rater reliability measured with ICC were all above 0.6 for identifying and grading intraoperative, pre and postoperative AEs and consequences of SCI.
  
  
  CONCLUSIONS
  The SAVES-SCI demonstrated acceptable intra-and inter-rater reliability for a majority of the AEs. Further clarification and definition of some of the AEs as well as provision of sample training cases for clinicians would assist in reducing measurement errors. The SAVES-SCI is a useful tool to assess and capture AEs in patients with acute traumatic SCI.
