title: Perceptions of health status in multiple sclerosis patients and their doctors.
abstract: OBJECTIVE
  To compare neurologist and patient perceptions of multiple sclerosis (MS)-related health status.
  
  
  METHODS
  MS patients (n=99) were recruited from six sites in Canada. Following a consultation with their neurologist, patients estimated their relapse frequency, rated their general health and quality of life (QoL), reviewed descriptions of eight health domains and selected the three most important, and completed a utility assessment using the standard gamble (SG). Concurrently, neurologists independently used the same instruments to rate their patients' health status. Assessments were compared on the basis of paired mean values of both groups and the degree of exact agreement quantified by intraclass coefficient (ICC) and kappa analyses, which yield values of 1.0 with 100% agreement.
  
  
  RESULTS
  There were significant differences (p<0.001) between patient and neurologist ratings for relapses in the last year (0.86 vs. 0.4, respectively), QoL (61.2 vs. 69.7 (maximum score = 100) and utility (0.864 vs. 0.971); ICC analysis revealed moderate to poor levels of agreement (0.56 for QoL to 0.03 for SG). There was little concordance in identification of important health domain and the only significant associations were in bodily pain and social functioning (kappa statistic = 0.24, p = 0.026 for both). Neurologists identified physical functioning domains as important, while patients placed more emphasis on mental health domains.
  
  
  CONCLUSIONS
  Discrepancies between neurologist and patient perceptions of MS were observed. The study identifies a need to educate neurologists on the recognition of MS health domains that are important in the definition of patient QoL.
