[Development of a methodological guide on the implementation of a pharmaceutical decision support system: Feedback from a French university hospital]

Objective: Develop a methodological guide on the implementation of a PDSS (pharmaceutical decision support system).

Method: Observational study, retrospective conducted at Lille University Hospital from May 2017 to December 2020, corresponding to the period of implementation and then use of the software. The different phases of the project are described as well as the methodology at each stage.

Results: Four stages seem necessary for the establishment of the PDSS: reflection and preparation of the project, contracting, implementation, use and evaluation. Based on these results and our experience, in particular the difficulties encountered, a methodological diagram of the various steps necessary for the implementation of a PDSS is proposed.

Conclusion: The establishment of a PDSS, especially in the field of clinical pharmacy, is a long multidisciplinary process. Several steps, from project preparation to production start-up are necessary. Planning the different stages is essential for the proper implementation of the SADP so that the installation is as efficient as possible.
