Signals from the Dutch national spontaneous reporting system: Characteristics and regulatory actions

PURPOSE

The aim of the study is to characterise safety signals based on the Dutch spontaneous reporting system (SRS) and to investigate the association between signal characteristics and Product Information (PI) update stratified by approval type: centrally authorised products (CAPs) versus nationally and decentralised authorised products (NAPs).

METHODS

This study evaluates the full cohort of signals disseminated from the Dutch SRS in the period from 2008 to 2017. Each retrieved signal was characterised on a number of aspects. The signal management process from signal generation to a potential PI update was analysed in four steps: (1) signal characterisation; (2) proposed actions by the Dutch national competent authority (NCA) for the signals; (3) presence of PI update (yes/no) and association with signal characteristics; (4) timing from the moment the signal was issued to PI update. For step 1-3 we stratified products in CAPs and NAPs.

RESULTS

Of all signals, 88.7% led to a proposed regulatory action by the NCA. Signals from the Dutch SRS for CAPs versus NAPs more often concerned biologicals, important medical events, class effects and shorter periods since marketing authorization. We detected PI updates for 26.2% of CAP signals and 61.3% of NAP signals.

CONCLUSIONS

The Dutch SRSs remains an important source of signals. There are some notable differences in the characteristics of signals for CAPs versus NAPs. Signals for NAPs more frequently led to PI updates.

Organ transplantation and the European Union, 2009-2015 developments

This article provides a high-level picture of the developments in organ transplantation in the European Union (EU) between 2009 and 2015. This was the period during which the European Commission and EU 28 member states developed an EU Action Plan on organ donation and transplantation. This plan was adopted by the European Commission in 2008, following calls for policy action to increase transplant numbers. It set out priority actions for member states and European Commission to address. This article describes the three main approaches used by the European Commission and National Competent Authorities to develop this action plan. We also present a quantitative comparison of 2015 and 2008 transplant data, based on the Newsletter Transplant by the Council of Europe (CoE) and the Spanish National Transplant Agency (ONT). This comparison shows contributions of different EU Member States, as well as of different donation and transplant programs to the overall increase of 4597 transplants per year (+16.4%). While another evaluation study of the action plan reported a strong positive impact of the action plan, it is beyond the remit of this publication to demonstrate a causal relationship between the EU Action Plan and the increase in number of organ transplants.
