4CPS-039 Six-month evaluation of the clinical and economic impact of pharmaceutical counselling in multidisciplinary day hospitals for geriatrics

<h3>Background and Importance</h3> For over 6 months, a geriatric Day Hospital (DH) (Onco-geriatric, memory, and fall assessment) has been established at our 428-bed hospital centre. These DH aim to optimise patient care by reducing medication related iatrogenesis among other things. <h3>Aim and Objectives</h3> The objective is to evaluate the clinical and economic impact of the pharmacist’s role in geriatric DH. <h3>Material and Methods</h3> This monocentric retrospective study took place from 1 September 2023 to 29 February 2024 in the outpatient medicine department of our establishment. The evaluation of pharmaceutical interventions (PI) was conducted using the French CLEO version 3 scale from the French Society of Clinical Pharmacy (SFPC). Only the clinical impact of a multidisciplinary team was assessed by using the CLEO scale. The economic evaluation of our hospital centre and internal pharmacy was carried out according to the French fee-for-service pricing of the Medicalisation Programme for Information Systems. <h3>Results</h3> In total, over 6 months, a pharmacist or pharmacy intern intervened in 88 DH sessions for 88 patients. A total of 183 pharmaceutical interventions (PIs) were made for an average of 2.1 PIs per patient. The CLEO clinical scale’s evaluation revealed that none of the PIs were harmful; 1% of the PIs (n=2) had a zero score, 26% (n=48) had a minor impact, 36% (n=67) had a moderate impact, 31% (n=57) had a major impact, and 2% (n=4) had a major impact that could prevent harm or lead to hospitalisation. An addition of 3% PIs (n=5) had an indeterminate score. From an economic perspective according to the French fee-for-service pricing, the average revenue is €744.26 for each DH session, resulting in a gain for the centre estimated at €65,494.88 over 6 months. With the intervention of 5 participants per DH session, the gain for the pharmacy would be €13,098. <h3>Conclusion and Relevance</h3> In total, at least 60 pharmaceutical interventions (PIs) contributed to a reduction in medication related iatrogenesis, preventing serious side effects for patients or hospitalisation. Pharmaceutical presence in DH has a positive clinical and economic impact, strengthening the safety and optimisation of care of elderly patients. It seems relevant to continue developing DH in other patient care pathways. <h3>References and/or Acknowledgements</h3> <h3>Conflict of Interest</h3> No conflict of interest
