Adverse drug events are frequent and may be mitigated with the implementation of functionalities within Health Information Systems. We developed a tool that allows Pharmacists to register and communicate to providers potential errors in prescribed drugs in terms of medication omission, unjustified stop of medication or other reasons.

We included all interventions performed by Pharmacists for admitted patients between July, 31st 2018 and October, 23rd 2018.

During the study period, 193 interventions were carried out by Pharmacists. 117 (60%) were intended for registering medication omission, 7 (4%) for unjustified stop of medication and 69 (36%) for other reasons. 112 interventions lead to the provider performing the suggested action (58%), 77 (40%) were rejected and 4 (2%) required no action.

Although there were errors in the use of the tool, a great amount of interventions were accepted, thus representing a better quality of care for patients.
