ABSTRACT
Due to the increasing complexity of medication regimens it is not always easy for the pharmacist to quickly and effectively screen the drug use of a particular patient for interactions. By means of a survey and a comparison, the advantages and disadvantages of the most common software packages available in Flanders were analysed. Major stumbling blocks of the currently available software are the high number of false positive signals, the absence of a history regarding the management of interactions, the lack of timely updates of the database and the absence of clear guidelines for the management of an interaction. Based on this research, we make the following recommendations: (1) signal fatigue should be reduced by interaction screening based on the duration of therapy in addition to the ability to suppress signals, (2) a log, coupled with the prescription-register, should be implemented, (3) software companies should help pharmacists more in configuring software preferences and provide them with better information bout the available options, (4) the underlying databases must be updated more quickly. (5) OTC medications, especially in the context of polypharmacy, should be registered in the patient record by the pharmacist, (6) note that food supplements are not included in the interaction screening software, unlike registered medication. (7) the knowledge of pharmacists regarding interactions should be maintained and improved.
