Bolded numerals indicate statistical significance.
The association between the variables sex, age, number of pre-admission drugs, number of discharge drugs, length of hospital stay and hospitalization before launch of the SMP, and whether or not patients experienced an undocumented medication discrepancy in regular, as-needed or OTC medications.
NA, not applicable, less than five observations in one or more of the groups; OTC, over-the-counter supplements and herbal medications; SMP, Danish national electronic Shared Medication Portal.
