Results:
A total of 355 stays were analysed, with PIs generated for 21.7% of the stays prior to COVID-19, and for 53.4% of the stays during the first wave (p=1.029 E-9). Among the 4,402 lines of treatments analysed, 54 PIs were carried out for prescriptions prior to COVID-19, and 177 during the first wave (p=0.002). DRPs were mostly related to anti-infectious drugs during the pandemic (20.3%, p=0.038), and laxatives prior to the pandemic (13.0%, p=0.023). The clinical impact of the PIs was mainly moderate (43.7%). The acceptance rate was 59.3%.
