Amélioration des connaissances des patients traités par un anticoagulant oral après avoir bénéficié d’un entretien pharmaceutique à l’hôpital

Abstract

Patients treated with oral anticoagulants need an adapted education in order to optimize the management of these treatments. The objective was to assess the knowledge of patients before and after a pharmaceutical interview carried out by pharmacy students on digital tablets at the hospital. A prospective study took place in the cardiology department, with a first phase from December 2016 to June 2018. Patient's knowledge were assessed during a pharmaceutical interview; additional informations were done for unacquired concepts. The second phase took place in October 2018, and patient's knowledge were assessed during a phone call for patients who had at least given one wrong answer on the four selected questions. Sixty-eight and twenty-two patients were included respectively for phases 1 and 2 (mean age=70±3.4; treatments number=8.2±0.9). 36 patients were treated by Vitamin K antagonists and 32 by direct oral anticoagulants. 57% of patients with oral anticoagulants gave a good answer for principles of the treatment and the surveillance during phase 1, and 33% for signs of overdose. A significant improvement for the 22 patients with poor knowledge was observed in phase 2 (1.73 vs. 2.5; P=0.006). The playful interview improves the patient's knowledge over time. Developing the relationship between the hospital and community pharmacists would allow us to optimize the patient follow-up.
