Brief Summary:

Breast screening is a service offered by the NHS to help detect breast cancer and precancerous changes early at a time when treatment is more likely to be curative. An effective service must reach the 'at risk' but asymptomatic population. Breast screening uptake in London, consistently falls below the national target and is well below the national average. Uptake in West London is particularly low, with boroughs in Inner North West London having the some of lowest uptake rates in the country.

Routine text message reminders have proven effective at improving uptake of breast screening appointments. However little attention is paid to the content of the messages. Previous studies of text message reminders in other clinical areas have shown that the content of these messages matters and some text messages are more effective than others.

This protocol describes the design of a randomized controlled trial to investigate the effect of differently worded text messages on the engagement with breast screening in West London.

Two intervention arms were designed taking into consideration results of a 1000 woman survey to highlight the behavioural barriers that most predict attendance. The survey tested 15 behavioural constructs and the two that most strongly predicted history of attendance were used to inform the text message content of the intervention arms for this trial.

To this end, this randomised controlled trial (RCT) will test the current standard practice text message reminder against two intervention text message trial arms informed by the above described survey.

The setting is West of London Breast Screening Service and women aged 47-73 who are due for screening will be randomized to receive one of the three trial arms.

The primary outcome is the difference in uptake between trial arms. Further statistical analysis will analyse the difference in uptake by age group, deprivation score and previous attendance status.

Result will inform how small changes to the word content may have significant effects on attendance at screening mammogram appointments.

Arm Intervention/treatment
No Intervention: Control
The current standard care text message reminder (SMS) that women routinely receive when being invited for their breast screening mammogram will be sent to the control group at 7 and 4 days before their timed appointment.
Experimental: Intervention A - Behavioural Regulation
Intervention A will be a text message reminder (SMS) containing a behavioural regulation message. Women will be sent this SMS at 7 and 4 days prior to their timed appointment.
Other: Intervention A - Behavioural Regulation

SMS reminder with 'Behavioural Regulation' message:

'Don't forget to make a diary note of your screening mammogram apt at (time)(date) at (site). Call 02033136644 to rearrange'


Experimental: Intervention B - Priority
Intervention B will be a text message reminder (SMS) containing a priority message. Women will be sent this SMS at 7 and 4 days prior to their timed appointment.
Other: Intervention B - Priority

SMS reminder with 'Priority' message:

'Is your breast screening appointment on your priority list? Apt at (time), (date) at (site). Call 02033136644 to rearrange.'





Primary Outcome Measures :
  1. Uptake of the timed appointment provided by the screening service [ Time Frame: Usually within a month (Individual timed appointment is provided by the screening service) ]
    Each patient is invited to an individual timed appointment. The outcome measure will be assessed based on if women attend their timed appointment. Usually this is within a month of the invitation letter being sent.


Secondary Outcome Measures :
  1. Uptake of time appointment by age group [ Time Frame: Usually within a month (Individual timed appointment is provided by the screening service) ]
    Each patient is invited to an individual timed appointment. The outcome measure will be assessed based on if women attend their timed appointment. Usually this is within a month of the invitation letter being sent.

  2. Uptake of timed appointment by number of previous invitations received [ Time Frame: Usually within a month (Individual timed appointment is provided by the screening service) ]
    Each patient is invited to an individual timed appointment. The outcome measure will be assessed based on if women attend their timed appointment. Usually this is within a month of the invitation letter being sent.

  3. Uptake of timed appointment by history of attendance [ Time Frame: Usually within a month (Individual timed appointment is provided by the screening service) ]
    Each patient is invited to an individual timed appointment. The outcome measure will be assessed based on if women attend their timed appointment. Usually this is within a month of the invitation letter being sent.

  4. Uptake of timed appointment by deprivation score [ Time Frame: Usually within a month (Individual timed appointment is provided by the screening service) ]
    Each patient is invited to an individual timed appointment. The outcome measure will be assessed based on if women attend their timed appointment. Usually this is within a month of the invitation letter being sent.
