If true, that's makes the author's credibility even lower.
It makes zero sense to divide the number of patients by patient days. The opposite would make sense, patient days / # patients = average patient days per patient. But it's way too soon to calculate that, as few patients would have been discharged by now.
If the author doesn't understand how to use the numbers, does he even understand what the numbers he is using represents? My guess is no, and this article should not be taken seriously.
Maybe the author was merely reporting what he was given and simply explaining why the percentage was so low?
