Clinical pharmacy as a guarantee of safety in times of crisis: evolution and relevance of the continued presence of clinical pharmacists in frontline medical units during the first wave of COVID-19.

BackgroundThe COVID-19 pandemic has had a major impact on the organisation of health services worldwide. In the first wave, many therapeutic options were explored, exposing patients to significant iatrogenic risk. In a context in which patient management was not well defined by clear recommendations and in which healthcare professionals were under great stress, was it still relevant to maintain pharmaceutical care or did it bring an additional factor of disorganisation? OBJECTIVE: The aim of our study was to compare the relevance of pharmaceutical care practices before and during the COVID-19 crisis. METHODS: A retrospective, comparative, observational analysis was conducted in two medical units in a French university hospital that were receiving patients with COVID-19 and benefiting from pharmaceutical care prior to the crisis. This study compared clinical pharmacy performance between two 1.5-month periods before and during the COVID-19 crisis. Performance was assessed according to the CLEO scale, rating the clinical, economic and organisational impacts of the accepted pharmaceutical interventions (PIs) performed in these units. RESULTS: Of the 675 accepted PIs carried out in the two medical units over the entire study period, PIs performed during the COVID-19 period had a greater significant clinical impact (72% vs 56%, p˂0.0001), a more positive economic impact (38% vs 23%, p˂0.0001) and a more favourable organisational impact (52% vs 20%, p˂0.0001) than those performed prior to the COVID-19 period. CONCLUSIONS: The health crisis generated important changes in care practices. Our study demonstrates the sustained relevance of pharmaceutical care during a health crisis. This local experience confirms the major interest in improving the integration of pharmaceutical expertise within French healthcare teams.
