Using Text Messages to Improve COVID-19 Vaccination Uptake
Can Behavioural-science Informed Text Messages Improve COVID-19 Vaccination Uptake in North West London? A RCT
COVID-19 vaccinations significantly reduce the risk of getting seriously ill or dying from COVID-19. Since December 2020, the UK has rolled out vaccinations according to the Joint Committee for Vaccinations and Immunity (JCVI) priority groups. However, despite data indicating that more than 90% of the UK population intends to get vaccinated, there are geographical and ethnic variations in vaccination acceptance. As younger cohorts with lower risk from COVID-19 become eligible for vaccination, it is expected that uptake rates may also be lower than they have been in previous cohorts.
It was recently announced that a national NHS text message service will be introduced to invite individuals eligible for the COVID-19 vaccine to book a vaccination appointment. Many GP practices and CCGs have already implemented text messages to invite eligible residents and patients for the vaccine.
However, recent research has shown that the message content of text messages inviting members of the public to other preventative health opportunities (e.g. personalised messages and GP-endorsements in cancer screening) can impact uptake.
This 3-arm randomised controlled trial will be conducted across the Central London (CL) Clinical Commissioning Group (CCG) which to-date has seen the lowest rates of COVID-19 vaccination uptake in the country. The study aims to investigate the most effective text message strategy to inform local, regional and national practice.
The intervention text message content to be tested is informed by behavioural science theory is personalised to include the recipient's name and GP practice name. All patients in the Central London CCG who are unvaccinated, aged 18-49, who have not declined the vaccine will be included as their cohort becomes eligible for vaccination according to the JCVI guidelines. The trial will compare the uptake of the COVID-19 vaccination by trial arm at 3 and 8 weeks after the intervention is deployed.

详细说明
The COVID-19 vaccine is an effective way to reduce morbidity and mortality from COVID-19. Increasing uptake of the COVID-19 vaccine is a major public health priority. People's willingness to receive the COVID- 19 vaccine in the UK has been at record highs - 9 in 10 people said they would receive it when the NHS notifies them that it is their turn. However, evidence suggests that willingness to get vaccinated is lower amongst younger age groups and BAME populations. Additionally, high willingness to be vaccinated may not translate into high uptake, particularly as the vaccine rollout extends to younger, less vulnerable cohorts.
Uptake of the COVID-19 vaccine may be influenced by many factors, including personal beliefs such as perceived low personal risk from COVID-19, perceived social and cultural norms or a concerns around vaccine safety or efficacy. Additionally, process barriers, such as the effort required to attend an appointment may reduce vaccine uptake. With more than 95% of UK households having a mobile phone, text messages can be an effective way to improve uptake of healthcare services and medicine adherence. In particular, recent research has shown that reminder text messages about flu vaccination appointments can improve uptake by up to 10%, and that some messages may be more effective for specific groups. However, more research is needed to maximise the effectiveness of messages to increase uptake of the COVID-19 vaccine specifically and to explore how the effectiveness of messaging differs across different age and ethnicity groups.
The proposed research will determine which message strategy increases COVID-19 vaccine vaccination rates in the cohort aged between 18 and 49 years old as they become eligible for the vaccine according to JCVI categories.
During the trial, each cohort that newly becomes eligible to be vaccinated will be randomised to one of the five trial text message strategies.
The trial arms will include the current practice text message invitation which will act as the control and four intervention trial arms. The intervention text message strategies and message content have been based on behavioural science theory.
The usual care team will deploy the text messages according to the trial arm allocation. The vaccination status will be recorded in the patients electronic health record (EHR) as per usual practice. Researchers will have access to the pseudonymised datasets through a secure data platform which only holds pseudonomised data (see data Study Procedure section).
Analysis will measure and compare the vaccination uptake across trial arms.
