If you are not "sure" you made a med error but think you might have, given 1.0 mL of a PO med instead of 0.9 mL on a q6h med (given twice), 2.5 mg possibly given instead of 2.25 with each dose, and it's been 2 days since you possibly made the error what would you do? (The pt is very young that's why the dose is so small). I don't know if there's a way to report "possible" error and I am truly not sure- I'd say it's a 70/30 chance that I made the error vs. didn't make it. I know it sounds stupid that I wouldn't be sure but this pt has several meds and I only realized the "possibility" the next day when drawing up the same medication- the concentration is 2.5 mg/mL. (Ironically the pt received a partial dose at one point the next day, d/t not closing one port of the GT and spilling part of the med). I have looked up the med online on reputable sources and can't find any serious issues with a higher than usual dose, though I know that is not the real issue when reporting med errors. It is metabolized in the liver and one liver enzyme was somewhat elevated about an hour after the pt received the last dose, but I don't know if that's related or not, the pt has multiple issues? I'm sorry this is so long... please help me out here. I'm not sure who else to ask.
