I relate to this. It was an initial source of friction where I work at that I was being “too aggressive” with my vanco dosing.
Never mind that most of the staff are so ridiculously under aggressive that we have people who complete therapy without ever getting to goal, obviously the real problem is me and actually wanting to get to goal before the end of therapy.
I had the exact same issue! My reasoning? Well, they are in the ICU with a blood stream infection so I would rather be aggressive and heal them than waffle around for three days while they are sub-therapeutic. I was only emboldened when I read an article that showed the risk of AKI with vancomycin was greatly overestimated and that it was older formulations of the drug that were riskier for that. I'm not sure if that is still the case, because I have ran as far away from that work environment as is possible while still retaining a "pharmacist" title.
