[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.

[Prophylaxis of venous thromboembolism in medical patients: from medical decision tools to the use of low molecular weight heparin]. / Prévention de la maladie thromboembolique veineuse en milieu médical: de l'aide à la décision à l'utilisation des héparines de bas poids moléculaire.

In France, low molecular weight heparins are largely used for prophylaxis of venous thromboembolic disease in medical patients. Although clinical trials show their efficacy in some particular clinical situations, there is no consensus about their use in non-surgical patients. A consequence is a wide disparity of prophylaxis of venous thromboembolic disease regimens: such a situation was observed during a practice survey in two medical units of the general hospital of Lunéville. So, prior assessment for pharmacists and physicians was carried out to determine tools which guide decision-making. These comprise clinical practice guidelines, a record card which allows the scoring of risk for venous thromboembolic disease and a clinical algorithm leading to the appropriate prescription according to the risk and the haematological results. A second concomitant practice survey was organized in the same two units in order to measure the appropriateness of the decision-making tools in medical practice. The four-month study included 108 medical patients. The process was successful because: (1) validated practices are improved, particularly in respect of biological monitoring during treatment, and (2) the disparity of therapeutic strategies is highly reduced, the clinical practice guidelines being followed in 81 per cent of all cases. Despite the lack of consensus, heightened awareness of the attendant risk in many medical conditions allows appropriate prophylactic measures to be taken. These measures need decision-making tools that are easy to use and that improve heparin prescribing and thus healthcare quality.
