[First French-speaking days of users of decision support system in clinical pharmacy: Feedback and perspectives]. / Premières journées francophones des utilisateurs de système d'aide à la décision en pharmacie clinique : retour d'expériences et perspectives.

Clinical decision support systems (CDSS) are tools that have been used for several years by clinical pharmacy teams to support pharmaceutical analysis, with a perspective of contributing to the quality of care in collaboration with the other health care team members. These tools require both technical, logistical and human resources. The growing use of these systems in different establishments in France and in Europe gave birth to the idea of meeting to share our experiences. The days organized in Lille in September 2021 aimed at proposing a time of exchange and reflection on the use of these CDSS in clinical pharmacy. A first session was devoted to feedback from each establishment. These tools are essentially used to optimize pharmaceutical analysis and to secure patient medication management. This session outlined the clear advantages and common limitations of these CDSS. Two research projects were also presented to put the use of these tools into perspective. The second session of these days, in the form of workshops, addressed 4 themes that surround the implementation of CDSS: their usability, the legal aspect, the creation of rules and their possible valorization. Common problems were raised, the resolution of which requires close collaboration. This is a first step proposing a beginning of harmonization and sharing that should be deepened in order not to lose the dynamics created between the different centers. This event ended with the proposal to set up two working groups around these systems: the creation and structuring of rules for the detection of risk situations and the common valorization of the work.

Nivolumab-refractory patients with advanced non-small-cell lung cancer.

INTRODUCTION: Immune checkpoint inhibitors (ICIs) have revolutionised cancer care especially in lung cancer. New response patterns have been described under ICIs such as pseudo-progression or hyper-progressive disease (HPD). The definition of HPD is yet to be consensual. The aim of this study was to suggest a clinical definition of nivolumab-refractory patients and find factors associated with this entity. METHODS: We performed a multi centric retrospective study including all patients who received nivolumab for the treatment of advanced non-small cell lung cancer (NSCLC) during the French authorisation for temporary use in 2015. RESULTS: 303 patients were included in the cohort and 292 had details on the number of nivolumab injections received. 57 patients (20%) were nivolumab-refractory. These patients had worse PS at nivolumab initiation (p < 0.0001), shorter duration of treatment before nivolumab (p = 0.028) and had dramatically shorter nivolumab overall survival (p < 0.0001) than patients who did not present with refractory disease. CONCLUSION: Nivolumab-refractory disease can affect up to 20% of patients treated with nivolumab for advanced NSCLC with dramatically shortened survival rates. Further studies are needed to understand the precise mechanisms leading to refractory disease as well as its management.

Impact of hospital pharmacist interventions on the combination of citalopram or escitalopram with other QT-prolonging drugs.

Background Citalopram and escitalopram can both induce dose-dependent QT prolongation. The risk of arrhythmia may be increased with concomitant use of other drugs that induce QT prolongation. Objective To evaluate the prevalence and impact of pharmacist interventions on the combination of citalopram or escitalopram with other drugs that induce QT prolongation. Setting A French hospital with 517 computerized beds. Method All cardiac adverse drug reactions (ADRs) related to citalopram or escitalopram reported to the French pharmacovigilance database (FPDB) were analyzed. Then, over a 6-month period, all computerized prescriptions including citalopram or escitalopram and drug-drug interactions (DDI) were analyzed by pharmacists using a computerized provider order entry system (DXCare®, Medasys). Results Only 27 cardiac ADRs related to citalopram or escitalopram were reported in the database. Among the 57,857 prescriptions and 2116 contraindicated DDIs (3.7 %) that were analyzed. 444 DDIs (0.8 %) were considered to be clinically relevant by pharmacists and physicians and 168 (i.e., approximately 30 %) were related to a combination including citalopram or escitalopram. Most of the prescriptions related to DDIs including citalopram or escitalopram were discontinued in response to a pharmacist intervention when initiated during the hospital stay. Conclusion A high number of hospital prescriptions including citalopram or escitalopram with another QT-prolonging drug occurred, highlighting the importance of involvement of clinical pharmacists in prevention of potential ADRs related to such contraindications.

[Market access agreements: Definition and features. Could MAA be defined as a solution for immunotherapy funding by French health system?] / Les contrats d'accès au marché : définition et caractéristiques. Une solution pour garantir la prise en charge de l'immunothérapie par le système de santé français ?

Over the last few years, many therapeutic innovations have been approved and marketed in France, within a strained financial setting. Legal dispositions allowed manufacturers (LEEM - les enterprises du medicament) and the economic committee for health products (CEPS) to contract various confidential market access agreements to contain health product expenses. The purposes of this article are to define and describe these different existing market access agreements and to open discussion on their applicability to the problematic of immune-oncology drugs financing. Financial agreements, which led to major savings (discounts refunded to the public payer), have not responded completely to the therapeutic innovations financing problems. Performance agreements (funding based on real-life data and effectiveness of the drug) constitute a hope for health products financing, but major methodological challenges for their use in routine restrict them to rare cases only today. Even though several financial agreements could partly respond to this problematic, use of performance agreements could really constitute an interesting track to tackle this issue.
