Welcome to the FOCUS trial website.

What is the FOCUS trial?

The FOCUS trial is a randomised controlled trial which aims to find out whether fluoxetine given to people for six months after a stroke improves long-term recovery, even if they do not have depression.

What does FOCUS stand for?

All trials need a 'snappy' name. We have selected 'FOCUS'. 'F' stands for Fluoxetine, 'O' for 'Or', and 'C' for 'Control'. 'US' stands for 'Under Supervision' to emphasise that we are monitoring patients' progress carefully throughout in the trial.

Recruitment has now closed! Thank you to all the participating centres and collaborators.

The FOCUS trial is aims to establish whether a six month course of fluoxetine, started within the first 15 days after an acute stroke, improves patients recovery over the first year. Also whether the treatment is cost effective (i.e. that any costs associated with the treatment are offset by health gains, and or reductions in healthcare and social care costs. This research aims to improve the care received by NHS patients and the use of NHS resources. Recruitment to the trial closed on the 31st March 2017. 3127 participants were recruited to the trial. The final patient and GP follow-ups for the patients recruited on the 31st March 2017 are due on 31st March 2018.

What we do with your information

The FOCUS trial team take our responsibility for looking after your information seriously. We take every step available to keep all data confidential in line with legal rules and guidelines. As FOCUS is researching long-term recovery and outcomes for participants and the cost effectiveness of the treatment we are interested to find out what happens. For this reason participants all patients in the UK will be followed up with NHS Digital in England and Wales (https://digital.nhs.uk/) and the Public Benefit Privacy Panel for Healthy and Social Care (in Scotland) (http://www.isdscotland.org/index.asp) at the end of the follow-up period of the trial. This will allow us to find out your status and if you have been admitted to hospital or attended hospital as an outpatient (Hospital Episodes Statistics (HES)) within the period of the trial and how long you have spent in hospital. We provide identifiable information (NHS/CHI number, Name and Date of Birth) to NHS Digital or PBPP. Both NHS Digital and PBPP have HES) dataset and which they can link to individual participants in the study. NHS Digital and PBPP are subject to strict regulatory standards to make sure care information is looked after in line with good practice and the law.

The reports we received from NHS Digital and PBPP will be imported into a securely accessed folder within the Edinburgh University ‘Safe Haven’ and used solely for the purposes of this research by the FOCUS study team. We will augment our FOCUS database with any new information provided by HES/PBPP.

Whilst the information received is specific to each study participant, no individual person will be identifiable in any publication arising from this work. Anonymous results of the study may be made available to collaborators with the appropriate agreements/approvals.

As contractually required, HES data is not kept for longer than necessary and will then be securely destroyed in accordance with the contract.

If study participants decide they no longer want their study data to be linked in this way they can withdraw from this follow-up, without affecting their current medical care in any way, by contacting Professor Martin Dennis, FOCUS Chief Investigator, University of Edinburgh, Centre for Clinical Brain Sciences (CCBS), University of Edinburgh, Chancellor's Building, 49 Little France Crescent, Edinburgh, EH16 4SB.
