Warning: Potential to misinterpret table

A pharmacist recently reported an error which occurred while determining an appropriate iron dextran dose based on a table listed on pages 33-34 of the most recent edition of Facts & Comparisons. The table lists estimated iron dextran requirements based on patient weight and hemoglobin levels. A footnote at the bottom of page 34 instructs the practitioner to use the lesser of actual body weight or lean body weight for patients weighing greater than 15 kg (33 lbs). The pharmacist in question used the patient's actual weight while referring to the table. However, the patient's actual body weight was much greater than the lean body weight, and the resulting dose was too high. The error was recognized before it reached the patient, and the dose was corrected.

In response to this event, the publishers of Facts & Comparisons changed the weight heading to read "lean body weight". The above-mentioned footnote still applies. Look for the correction in the August supplement. The publishers are considering further revisions that will make the information easier to understand, thereby decreasing the chance of incorrect dosing.
