a

ACS = acute coronary syndrome; HF = heart failure; OR = odds ratio; PADE = potential adverse drug event.

b

Analyses were calculated per unit increase for the parameters: age, Charlson index score, health literacy score, No. of prescribed medications, No. of admissions in previous 12 months.

c

Admission diagnoses divided in 3 groups: heart failure, acute coronary syndrome, and other. Heart failure and acute coronary syndrome groups were each compared to other.

d

Heart failure pertains to the presence of the comorbidity, regardless of the admission diagnosis.

e

Medication handling was divided in 3 groups: patients handling their medications on their own (no help; reference group), family helping patients (patient still participates), and family handling all medications (patient unable to handle any of the medications). Family helping and family handling all medications groups were compared to the reference group.

f

The numbers for nonadherent and doubtful adherent were very small and did not reach statistical significance. Results of readmission (30 days or 6 months) of nonadherent vs adherent.
