I see the part about the “typical inpatient may receive 20-plus doses of meds daily”, but I have to ask (not that I doubt Cecil), but really? Should I just expect that when I go in for an inpatient that I am incredibly likely to get a wrong med script? That’s truly frightening.
The statistic is undoubtedly correct; the usual signs of error are missing because not only does Unca Cece give an explanation for the figure (indicating that even HE would have thought wth?), but also 100 of those are SERIOUS. So about one in ten mistakes is serious, not an unsurprising stat in itself, and, thus, making the number 1400 consistent.
Remember, an admission can last a long time, and a patient can get many doses a day, so an admission might have something like 400 + doses over a 20 day hospital stay. Let’s say that the error rate on that is 1%. Then, that “admission” got 4 prescribing errors. Now that is a ratio of 4 to 1, but not as scary as saying that every patient is regularly getting prescribing errors.
Any attempt to conflate all inpatient treatment to an average number of doses, and call some errors “serious” without regard to context, is bound to give you some scary numbers.
