Release of Annual Report for National Medical Device Adverse Event Monitoring (2018)

Updated: 2019-10-30

    

 

To fully reflect the monitoring of adverse events in China's medical devices in 2018, the National Center for Adverse Drug Reaction Monitoring has compiled and released on October 30, 2019 the Annual Report for National Medical Device Adverse Event Monitoring (2018), which is excerpted as follows: 

I. Progress of medical device adverse events monitoring 

In 2018, with the pioneering efforts of our staff, the national medical device adverse event monitoring has continued to advance, the monitoring scope continued to expand, the report collection capability was significantly improved, and the number of reports saw a persistent increase. The ability of monitoring personnel to analyze and evaluate adverse events has been continuously improved to effectively detect and deal with risks, the principal responsibility of manufacturers' monitoring of adverse events has been gradually implemented, and new progress has been made in this field. 

(I) The construction of monitoring information system has been promoted, and network coverage has been expanded to improve data quality

In 2018, the Information System for National Medical Device Adverse Event Monitoring has received more than 400,000 Reports for Suspected Adverse Events of Medical Devices, and the quality of the reports was improved. There are more than 270,000 registered users at the grassroots level of the system, of which more than 13,000 are manufacturers, an increase of 16.44% over last year. 95.9% of districts and counties across China reported medical device adverse events, with an average of 305 reports per million people. In addition, the National Center for Adverse Drug Reaction Monitoring completed the establishment of a new information system for monitoring adverse events in medical devices, realizing the replacement of the online reporting system for such events in China, provide strong support for the implementation of the Administrative Measures for Monitoring and Re-evaluating the Adverse Events of Medical Devices (hereinafter referred to as the Measures) . 

(II) The analysis and evaluation of monitoring data are reinforced for product risks mining and promoting the safety of medical devices. 

In 2018, the evaluation and disposal of risk signals for the monitoring of adverse events in medical devices were carried out in depth. We've strengthened the daily monitoring, early warning analysis and quarterly summary of national medical device adverse event reports. Based on the risk conditions, 3 issues of Medical Device Adverse Event Information Notification and 6 Medical Device Pharmacovigilance Expresses were issued throughout the year. The intensive monitoring of adverse events in medical devices 13th Five-Year Plan continued to advance. The National Center for ADR Monitoring has organized inspections on key surveillance work. The relevant undertaking units proactively collected monitoring data to dig deeper into the risks of medical devices, and the relevant work saw steady progress. 

(III) We carried out technical training on monitoring regulations, and actively participated in international exchanges to improve the level of the monitoring teams 

To support the implementation of the newly revised Measures, the National Adverse Drug Reaction Monitoring Center trained a total of 393 monitoring institutions throughout the year, achieving full coverage of training at provinciallevel monitoring institutions. Supervision departments at all levels have organized special training courses on the Measures and related guiding principles to improve the ability of monitoring personnel and reinforce the principal responsibility of production enterprises. In addition, we actively followed up the progress of adverse event terminology in IMDRF (International Medical Device Regulators Forum) and promoted China's participation in the National Competent Authority Report (NCAR) System, which further enhanced the level of internationalization. 

II. General situation of medical device adverse event reporting 

(I) Overview of reporting in 2018 

1. Number of Medical Device Adverse Event Reports in China   

In 2018, the National Medical Device Adverse Event Monitoring Information System received a total of 406,974 reports of suspected medical device adverse events, an increase of 8.19% over 2017, reflecting the increasing awareness of China's medical device adverse event reporting and the effective enhancement of report collection capabilities (Figure 1) .
