Plain English Summary

Background and study aims
Burnout affects 20-40% of NHS clinicians. Clinician burnout is linked with worse patient outcomes, reduced clinician wellbeing and negative financial implications for health services. Reducing clinician burnout therefore has the potential to improve healthcare and patient safety. This study aims to reduce burnout and improve wellbeing in trainee anaesthetists through a series of behaviourally informed text messages.

Who can participate?
Anaesthetists in training, working in a UK hospital, registered with the Royal College of Anaesthetists, in training years CT2, ST3, and ST4 are eligible to participate.

What does the study involve?
Half of the trial's participants will be randomly allocated to receive a series of fortnightly supportive text messages over a period of 10 months. The other half (the control group) will receive sign-posting to self-help materials via text. Participation will also involve completion of two short follow-up wellbeing surveys after 3 months of text messages and then again at the end of the trial period (after 10 months of text messages).

What are the possible benefits and risks of participating?
The possible benefit to participants is that their wellbeing might improve and their burnout level might reduce. The risk for research participants in this trial is that the text messages may have an unintended backfire effect, and worsen trainee wellbeing and increase burnout. This risk has been minimised by developing the text messages following a listening exercise with trainees. In addition, the proposed message content and wording has been reviewed and approved by the RCoA and a panel of trainee anaesthetists. Another risk to trainees receiving the intervention messages is that some messages ask the trainee to do something e.g. “Take a moment to think about what makes you a good doctor”. Trainees are very busy and might feel that these texts add to their list of things to do. This burden has been minimised by careful consideration of what to include in the messages. Suggested tasks are small, and taking action on the advice given is optional. In addition, the first message will contain instructions for how trainees can opt to stop receiving the messages if they feel they are too burdensome.

Where is the study run from?
The researchers are based in London. Participants take part in this study from all over the UK.

When is the study starting and how long is it expected to run for?
Recruitment starts on 11/09/2019. The first intervention message is sent approximately one month later and the intervention runs for 10 months.

Who is funding the study?
The Patient Safety Translational Research Centre, Imperial College London.

Scientific title

Can a behaviourally informed text message intervention reduce burnout and improve wellbeing in trainee anaesthetists, compared to signposting to pre-existing self-help materials?



Study hypothesis

A behaviourally informed text message intervention will reduce burnout and improve wellbeing more than signposting to pre-existing self-help materials.

Ethics approval

Burnout and wellbeing in trainee anaesthetists


This will be a 2-arm individual-level randomised controlled trial, where all participants are sign-posted to self-help materials upon completion of a baseline survey and through an initial text message. Participants will be randomised to treatment or control groups using a random number generator in Stata. Treatment participants will receive a series of 23 fortnightly supportive text messages (over 10 months) incorporating a variety of behavioural insights as well as research from the science of wellbeing. Control participants will receive business-as-usual, i.e. no special support beyond being directed to self-help materials for managing burnout. Both control and treatment participants will be asked to complete two further surveys: a midline survey at 4 months (3 months after first text) to ensure the intervention is not having an unintended backfire effect; and end survey at 10 months. All participants will be sent up to 2 reminder messages to complete each survey. At the end of the intervention period, participant feedback on the intervention materials will be sought via a survey.

Intervention type



Drug names

Primary outcome measure

1. Wellbeing is measured using the Short Warwick-Edinburgh Mental Wellbeing Scale [SWEMWBS] (7 items) at baseline, 3 months and at the end of the intervention.
2. Burnout is measured using the Copenhagen Burnout Inventory [CBI] (7 items) at baseline, 3 months and at the end of the intervention.

Secondary outcome measures

1. Meaningful work is measured using the question “How meaningful do you find your work in general?” [0-10 scale] at baseline and at the end of the intervention.
2. Feeling valued is measured using the question “Overall, how valued do you feel as a trainee anaesthetist?.” [0-10 scale] at baseline and at the end of the intervention.
3. Absenteeism is measured using the question “Over the last 6 months, approximately how many sick days have you taken off work?” at baseline and at the end of the intervention.
4. Intention to stay in profession is measured using the question "Are you considering taking a break in your training in the near future for wellbeing or mental health reasons?" [Yes/No] at the end of the intervention.

Results and Publications

Publication and dissemination plan

The results of the trial will be published in a peer-reviewed journal. A report will also be made available for circulation to a wider, lay audience. We will report the trial findings back to our Burnout Advisory Board, which is made up of clinical and academic experts in the field and includes senior members of the Royal College of Anaesthetists (BIT’s trial partner in this research).

IPD sharing statement: the datasets generated during and/or analysed during the current study are/will be available upon request from Alix Brazier, The data will include the outcome measures and will be de-personalised/anonymised. Data will be available 3 months after article publication and will remain available for 3 years. Data will be made available via secure server with researchers who provide a methodologically sound proposal to achieve the aims set out in their approved proposal. Participants consented to no personal data being shared. All data will be fully anonymised. We have spoken to both our legal and ethical team who have agreed to this.
