Medico-economic Analysis of Clinical Pharmacy Activities

Overview

In recent years, the deployment of clinical pharmacy activities in France has undergone rapid change as a result of the work carried out by the French Society of Clinical Pharmacy (SFPC), organisational innovations (iatrogenic day hospital, city-hospital pathway) and new regulations (adaptation and renewal of prescriptions by hospital pharmacies). This transformation is causing disparities between hospitals in the deployment of clinical pharmacy activities and a lack of clarity in the activities of each. At the same time, the traceability of these clinical pharmacy activities is a major strategic challenge, as it meets regulatory requirements (pharmaceutical analysis linked to dispensing), safety requirements (pharmaceutical interventions, reconciliation of drug treatments), financial requirements (day hospital, medical and rehabilitation care, outpatient consultations) and quality requirements (reglutory indicators, mandatory certification). Some healthcare institutions have launched local initiatives to code their clinical pharmacy activities themselves. These experiments have demonstrated the need to standardize coding across French healthcare institutions, in order to bring it into line with current guidelines (French Health Authority - HAS - guidelines, good clinical pharmacy practice, decree) and the coding rules of the common classification of medical acts. The ultimate aim of such coding is to qualify, in the long term, for financial recognition of clinical pharmacy activities via the Health Insurance System. To meet this need, in March 2023 OMEDIT PACA-Corse published a coding guide for clinical pharmacy activities, validated by the SFPC and deployed to date in a number of French establishments. Based on national coding, the investigators propose to carry out a medico-economic analysis using observational data, in order to assess the efficiency of integrating clinical pharmacy activities into patient care pathways. The aim of this study is also to initiate a process of reflection to define the pharmaceutical costs associated with clinical pharmacy activities. The investigators hypothesize that the costs of implementing clinical pharmacy (hospital pharmacist salary) will be covered by the costs avoided in terms of adverse events. A single-centre, prospective, non-interventional and comparative cohort study will be carried out in 4 different care pathways with 2 different sites targeted for each pathway: one site carrying out clinical pharmacy activities with patients as part of routine care (active group) and one site carrying out no clinical pharmacy activities with patients as part of routine care (comparator group). The study takes place in the same way in each of the 4 pathways, with 3 distinct phases: Phase 1: Collection of routine care data during hospitalisation: * In the active group: no research-related procedures are carried out on the patient. The patient benefits from the clinical pharmacy activities offered as part of routine care. The pharmacist records the time spent with the patient for each clinical pharmacy activity performed during the hospital stay. * In the comparator group: no research-related activities are performed on the patient. Patients benefit from the routine care pathway defined in their hospital ward. Phase 2: Collection of routine care data at 3- and 6-months post-hospitalisation: \- In the active group and in the comparator group: consultation of the computerised patient record to collect adverse events related to drug management that occurred at 3- and 6-months post-hospitalisation (emergency room visits, hospitalisation, drug-related iatrogenicity); Phase 3: Telephone call to the patient 3- and 6- months after hospitalisation: \- In the active group and in the comparator group: evaluation via a questionnaire of adverse events related to drug management which occurred in the 6 months post-hospitalisation (emergency room visits, hospitalisation, drug-related iatrogenicity, consultation with the treatment physician). The call at 3 months is optional.
