therapeutics, the proposed PP and its acceptance are collated in an Excel file); then discussion and validation of the results in Medicines and Sterile Medical Devices Commission (MSMDC), in particular for the not accepted PIs. ResultsThe flowchart criteria are kalemia, oral intake, KCl-inj concentration, KCl-inj in prevention during high-dose hypokalemic treatments, initiation of treatment. Each of the situations identified is linked to a PI or the absence of PI. 6 axes of PP have been identified including oral co-prescription, switch by electrolyte solution, and adaptation of the volume of solvent.The study over one month gives 172 lines with a MR according to our tool. 85 prescriptions were compliant. 87 PI formulated including 6 without PP. The PI acceptance rate is 43.2%, with a maximum of 52% for the oral relay and a minimum of 0% for adaptation of the volume of solvent or electrolyte solution switch. At the end of the MSMDC, our tool is validated after an agreement on the importance of promoting the use of electrolyte solution. Conclusion and RelevanceThe acceptance rate and the conclusions of the MSMDC allow us to validate the flowchart. Its use improves the relevance of PIs, their acceptance and reduces the use of KCl-inj. To facilitate the use of the tool, an Excel file that identifies the PPs according to the criteria is being developed.
