Respondents represented 15 hospitals across each region of Canada
(response rate=52%). Only 39.2% of respondents reported routinely
measuring ASP levels, yet 53% of respondents have modified therapy from
PEG to Erwinia in up to half of their patients. The most common
reason for not measuring ASP levels was not knowing how to use levels
clinically (25.5%). There was variation in the timing of levels and
their target.
