AbstractWe sought to examine hospital compliance with poison center antidotal alcohol dehydrogenase inhibition recommendations in cases of ethylene glycol (EG) and methanol (ME) ingestion. A 2-year analysis of all potential EG and ME ingestion cases reported to a regional poison center was conducted. Excluded from analysis were exposures without an ingestion, without a confirmatory EG or ME serum assay, or without complete medical charting. During the study period, 579 EG or ME exposures were reported to the poison center: 133 cases met study eligibility as an ingestion. Of the 133 cases, 102 (77%) had complete data and were included in the analysis. Immediate alcohol dehydrogenase inhibition was recommended by the poison center in 79 of the 102 cases. Fomepizole was recommended in 61/79 (77%); ethanol was recommended as an alternative therapeutic choice in 32/61 (52%) of these cases if fomepizole was not immediately available. Ethanol alone was recommended in 18/79 (23%). Fomepizole was eventually administered in 39/61 (64%) cases where recommended. The mean time to antidote administration was 3 times longer in cases where a choice in antidote was given [57 min (95% confidence interval, 43-70) vs. 146 min (95% confidence interval, 93-200)]. Despite its ease of administration, fomepizole is used less frequently than recommended by poison center staff. Delays to antidote administration occurred more commonly in cases where the poison center gave a choice in antidotal therapy.
