Results from the multiple logistic regression analysis reported as odds ratios (OR). Model 1 only includes Anatomical Therapeutic Chemical (ATC) group as explanatory variable. Model 2 includes ATC group and the number of reimbursements as explanatory variables. Calculations are corrected for patient's sex and age, although these variables were without statistical significance.
†
Prescribed drugs were identified as drugs registered in pharmacy records 0–30 days before admission.
