To the Editor We read with interest the article by Himmel and colleagues1 that discussed the institution of hemodialysis for an erroneous laboratory result and would like to add some additional points. We wish to empathize with the authors, because we reported 3 cases in which a 10-fold misinterpretation of salicylate concentrations produced similar cognitive errors.2 As in the case reported by Himmel and colleagues, there was an intellectual disconnect between the clinical findings of poisoning and the laboratory result that would have been easily solved by a seasoned clinician.
