title: Access to multiple sclerosis diagnosis for Canadian neurologists.
abstract: BACKGROUND
  Access to multiple sclerosis (MS) diagnosis in Canada has never been assessed. This study was designed to examine the pattern of MS diagnosis in Canada, including neurologists' diagnostic approach and waiting times for investigations.
  
  
  METHODS
  A mail survey was forwarded to every registered neurologist in Canada (n = 479) in late 1996. Questions included their diagnostic approach to MS including perceived waiting times for various investigations including MRI. Actual MRI waiting periods were separately obtained from booking clerks or neuroradiologists from every MRI unit in Canada.
  
  
  RESULTS
  153 responses were received. Neurological assessment is obtained, on average, 1 month after referral. MRI is routinely ordered by 92% of neurologists for suspected MS followed by evoked potentials (EP) (36%) and lumbar puncture (LP) (17%). The perceived waiting period for EP and LP is less than one month but 3 months for MRI. This is very similar to the actual waiting periods obtained from the MRI units surveyed (mean of 101 days). There is a trend for longer waiting periods as one moved east to west (Eastern provinces--mean of 62 days, Ontario--95 days, Quebec--102 days and 122 days in the Western provinces). Private MRI units have appeared in the Western provinces and have the shortest waiting periods (2 weeks maximum). The current MRI/million population ratio in Canada is 1.8, far below the ratios of other developed nations.
  
  
  CONCLUSIONS
  Canadian neurologists prefer MRI of the brain to confirm an MS diagnosis and desire greater access to it. Access to neurological assessment, EP and LP is probably adequate but the average wait for MRI of 3 months is relatively long. The perceived average waiting period for MRI is similar to the actual waiting times of 3 months, with the Western provinces of Canada having the longest waits. Canada continues to have one of the lowest MRI/population ratios in the developed world.
