The Opinion of Healthcare Professionals About a Proposed European Registry of Neuromodulation for Chronic Pain: An Online Survey

INTRODUCTION: During the last decade, the complementary value of real-world data (through registries or medical records) and data from randomized clinical trials has been recognized as increasingly important. In the field of neuromodulation, only a few industry-independent nationwide neuromodulation registries are available. The interest in creating a European registry has increased but without a successful result. The goal of this online survey is to gain further insights into the need for and burden of a European registry for neuromodulation.

MATERIALS AND METHODS: An online survey was developed and distributed during the 3rd Joint Congress of the International Neuromodulation Society European Chapters in September 2023 (Hamburg, Germany). Healthcare professionals were asked to indicate the need for a European registry, the items that should be collected, and the restrictions to access of a European registry.

RESULTS: In total, 125 respondents opened the link to the survey, of whom 104 completed (at least partly) the survey. Of the 104 responses, 91% indicated that there is a need for a European registry, whereas 6% indicated there is no need. The main reasons for establishing a registry on a European level were the possibility of collecting real-world evidence (84%), the potential to collect big data from European patients (82%), to evaluate safety in neuromodulation (70%), and the possibility of reporting yearly on European activity in neuromodulation (51%). Indications for neuromodulation, patient characteristics, and follow-up assessments were most often stated as items that should be collected. Access should not only be granted to implanters but also to nurses, the assessment team, and other physicians, as agreed on by 64%, 52%, and 51%, respectively.

DISCUSSION: More than 90% of the respondents believed that a European registry for neuromodulation is needed, mainly to obtain real-world (big) data about the effectiveness and safety of this therapy. This survey clearly pointed to the need for a European registry for which it seems key to ensure financial and logistical support, in addition to in-depth legal guidance in developing this registry.
