Study summary

This is a retrospective non-interventional study to describe the HCRU and clinical outcomes before and after AspireSR® device implantation in subjects with drug resistant epilepsy at the Queen Elizabeth Hospital, Birmingham (QEHB).

Read the detailed description

Real-world data on healthcare resource use (HCRU) for subjects with treatment-resistant epilepsy and their clinical outcome prior to- and post-VNS device implantation in the UK are limited.

The current study aims to describe and compare the secondary HCRU and clinical outcomes prior to and following AspireSR® device implantation in subjects with drug resistant epilepsy.

Retrospectively-collected data from hospital medical records (paper-based and/or electronic, as appropriate) will be used to describe subject characteristics, disease control and clinical outcomes. All secondary HCRU data will be extracted from the Hospital Episode Statistics (HES) database by Harvey Walsh Ltd (HW, trading under OPEN VIE). Primary HCRU data will be requested from the subjects' general practitioners (GPs).

Study population

Male and female adult (aged ≥18 years at AspireSR® implantation) subjects with epilepsy who have had the VNS device AspireSR® implanted at least 24 months prior to study retrospective data collection.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 years at AspireSR® device implantation.
  • VNS device AspireSR® implantation for the first time or battery change from a previous model to AspireSR® at least 24 months prior to the start of retrospective data collection from medical records.
  • Subjects for whom written has been provided for researcher access to their medical records and extraction of data from HES (if the subject is living and has capacity to consent) or advice from a consultee (if the subject is living but lacks capacity to consent).
  • Subjects with available medical history for at least 24 months prior to Aspire SR® implantation.

Exclusion criteria

Exclusion Criteria:

  • Living subjects for whom consent for researcher access to medical records and extraction of data from HES has not been obtained.
  • Deceased subjects.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

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.
