Abstract:

Background: Spontaneous reporting system is most widely used by pharmacovigilance systems. Its �??voluntary nature�?� represents the main cause of adverse drug reactions (ADRs) under-reporting phenomena. Objective: To point out the issue of ADRs under-reporting from hospital doctors, above all of �??serious�?� ADRs and of adverse reactions caused by medicinal products subject to additional monitoring, such as novel oral anticoagulants (NOACs). Methods: We just analyzed serious ADR, defined as ones responsible for: death, life-threatening, hospitalization (initial or prolonged), disability (significant or permanent), and congenital anomaly. As a first step, we analyzed suspected adverse reactions alerts to NOACs submitted to the Area Vasta 2 (ASUR Marche) pharmacovigilance centre, from 16 June 2013 until 14 January 2017. Furthermore, we examined alerts coming from all over Italy and from the Marche region. In a second step, we just worked in Senigallia hospital; retrospectively, we identified some patients who experienced an ADR in that period of time and we submitted the alert. In a third step, from 15 January 2017 until 15 March 2017, we submitted suspected ADR alerts prospectively. Results: Phase 1: in 43 months, 1625 alerts have been submitted from all over Italy, 20 from the Marche region (one of them from the Senigallia Hospital). Phase 2: retrospectively, we collected eight suspected serious ADR, two of them resulting in death and three of them life-threatening. Phase 3: in just two months, prospectively, we observed seven serious ADR, two of them resulting in death and one of them life-threatening. Conclusions: Our study has shown that under-reporting phenomena are remarkable from hospital doctors and it also concerns medicinal products subject to additional monitoring and serious ADRs. In our opinion, the introduction of a system of �??rewards�?� for doctors who correctly report ADRs or a system of �??sanctions�?� for doctors who don�??t respect this important duty should be attempted.
