Unfortunate mishap or gap in care warranting change in provider: 87 y/o (my grandfather) on two rapid-acting insulins (no basal) for 2 months.
I'm trying to figure out whether a recent medication error with my grandfather was just an unfortunate mishap, or if it reflects a problem with his endocrinologist's care that should lead us to consider switching providers.
Here's what happened:
My 87 y/o grandfather with type1 DM for 60 years was supposed to switch from Humalog to Novolog (both short-acting insulins) at the end of March, and at the same time start Soliqua as his basal insulin.
Instead, he ended up taking both Humalog and Novolog, thinking those were the two insulins he was supposed to be on, and never received/started the Soliqua. i.e. instead of a Basal-Bolus regimen, he was effectively taking two nearly identical short-acting insulins without basal coverage.
This medication change so happened to occur just before my grandmother was hospitalized, which is relevant both because he was likely inconsistent/variably compliant with his already-incorrect regiment for the month she was hospitalized, and also because I moved in last week to help care for her after discharge.
I'd never seen a continuous glucose monitor before and didn't even realize he had one (which, in hindsight, should've been obvious). So it wasn't until about 2 days in when I finally checked what in the world that incessant, annoying beeping was that I found the monitor flashing "danger: 37 BGL."
It happened again the next day, so I had him walk me through his regiment and proceeded to make an urgent appointment to his endo 3 days later, keys in hand ready to take him to ER if he became symptomatic. In that time his sugars swung wildly from 40s to 300+ daily. He thought it was normal, just treating the lows with honey and ignoring the highs. (Oh, and that was for when he actually heard it beeping, which was maybe 20% of the time since he stubbornly refuses to wear hearing aids and can't hear the damn thing).
If I hadn't been staying with them, the only way I see that being caught would've been either in the ER after a hypoglycemic emergency or if he made it the 6 more weeks until his next appointment.
I understand that medication errors happen and that responsibility is shared across patient, physician, and pharmacy. But this feels like the kind of error that shouldn't be able to happen, especially not one that goes undetected for over 2 months, essentially by chance.
Bottom line: Was this within the bounds of reasonable care, or does it suggest a gap in oversight that should factor into whether we continue with this endocrinologist?
Would really appreciate insight, especially from clinicians or pharmacists familiar with how these systems are supposed to work.
