Table 1

Data of the 91 patients receiving paracetamol.

Gender (female/male)	59/32
	Median (range)
Age (years)	86 (68–101)
Duration of hospitalization (days)	8 (1–31)
Number of other drugs upon admission^A,B	7 (0–19)
Number of drugs at discharge^A	9 (2–20)
Number of drugs, total exposure^A	15 (4–29)

^ANot including paracetamol. ^BEight patients did not have any registration of their medication history upon admission. The number of drugs upon admission was registered from the medication history described in the patients’ journals upon the admission (not necessarily from the Department of Geriatric Medicine). The numbers of drugs at discharge and total exposure were registered from EPM and include both regular and PRN medication, and all prescriptions were registered except fluid infusions. The drugs were categorized in ATC codes. EPM = electronic patient module; PRN = as needed; pDDIs = potential drug-drug interactions; ATC = Anatomical Therapeutic Chemical Classification System.
