SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.
SOCRATES is a non-randomized, multisite, single-arm, open-label, global post-market observational data collection per standard of care. While generally of prospective design, a limited retrospective element is allowed for the inclusion of patients for a short period of 10 days after their index procedure.
SOCRATES intends to enroll a number of subjects that will support the analysis of all the individual Post Market Clinical Follow-Up (PMCF) Plans. An average of approximately 100 subjects per year and site on a continuous basis is expected but may vary depending on the needs of individual PMCF Plans. As long as SOCRATES is active, there is no upper limit to the total number of subjects that may be enrolled, and enrollment will be driven by the need to support sample sizes of individual PMCF plans for given products/product groupings supported by SOCRATES.
SOCRATES is designed to be a continuous effort after the data collection commences without a predefined closure timepoint. Data collection and enrollment may be stopped, restarted or finalized per Sponsor discretion.
The expected duration of SOCRATES participation for a subject is dependent on
For BSC implantable devices subjects are intended to be followed for the entire time of being implanted with a BSC device to allow data collection over the lifetime of the device(s) as required by applicable regulations. A maximum duration per enrolled subject is not defined, unless locally required. In case a local maximum duration is enforced subjects may be consented again and re-enrolled for continued participation if they are still in scope for SOCRATES. Sites shall ensure continuous data collection without any gaps in case a re-enrollment becomes applicable. Data sets for re-enrolled subjects will be handled as if the subject was continuously enrolled. This process will ensure to meet the requirement of MDR for device manufacturers to collect data over the lifetime of the devices.
2,135 studies on the registry are indexed under Heart Diseases; 252 are open to participants now.
This study's planned enrollment of 12,500 is above the median of 350 across 592 observational studies indexed under Heart Diseases.

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Started Mar 2021 (actual). Primary completion is estimated for Dec 2030, 117 months after the start.
Of 54 industry-sponsored observational studies under Heart Diseases, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 65. This study's planned 117 months is above that.
Counting every sponsor, half of 238 studies reached it within 45 months; a quarter within 18 and three quarters within 95.
