Background The emergency medicine (EM) pharmacist, on working days, performs medication review and reconciliation. The EM pharmacist communicates, verbally or through small reports, the interventions to the doctor. After the electronic prescription (EP) implementation, in October 2017, these reports changed to a messaging system of the prescription programme.

Purpose To analyse the impact of the EP on EM pharmacist interventions.

Material and methods Unicentric, observational and prospective study conducted in a tertiary university hospital. We included all patients in the emergency department observation area (30 beds). The interventions reported in the first semester of 2017 (pre-intervention) were compared with the first semester of 2018 (post-intervention).

The results of this activity were collected in a spreadsheet (Excel). We recorded the intervention type and its acceptation.

Results In 2017, 1178 patients had at least one intervention on their medication (29.7% of the total) and we performed 1605 pharmaceutical interventions (1.4 intervention/patient). In 2018, 491 patients (12.4% of the total) and 744 interventions (1.5 intervention/patient).

Conclusion Interventions (both number and patients) have been reduced to more than half after the EP implementation. This suggests an improvement in the quality of the prescription.

• There is a change in the interventions profile. Therapeutical exchange decrease sighnificantly because the EP programme only allows prescription of medication included in the hospital therapeutical guide.

• The messaging system is a point of improvement because the acceptance of interventions have decreased.
