Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will test an administrative intervention using automated SMS to improve patient engagement in primary care. A simple short messenger service (SMS) will be sent by the general practice clinic to prompt patients to attend for a planned asthma review, and obtain an up-to-date asthma action plan. Any patients who do not respond will be sent a second and final SMS reminder one month later.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomised by computer to either intervention (SMS receiving group) or care as usual. Allocation to group will be concealed from research staff and participants as group allocations will be randomly generated by a computerised system at conclusion of recruitment of participants into the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by computer software.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Type of endpoint(s)
Efficacy
Statistical methods / analysis
Data will be analysed using intention to treat and a chi-squared test for differences in proportions between the intervention vs care as usual (control) groups for (a) attendance at the clinic for a planned asthma review and (b) obtaining an up-to-date asthma action plan.

Summary
Brief summary
We know that asthma is a common but serious illness that causes deaths in otherwise healthy people, including young people and children. While asthma can’t be cured, it can be managed but this does require regular review of symptoms and medications, particularly because the disease can vary in severity over time, with different triggers affecting this. One strategy to improve asthma management is an asthma action plan. This is a written document that outlines how a patient’s asthma can be managed. It is individualized for each patient, and for different levels of asthma severity. It has been shown that having an asthma action plan reduces asthma mortality, yet many patients with asthma do not have a current up-to-date action plan. Part of the reason for this is that many patients with asthma only attend when they are unwell and do not attend for a planned visit to review their asthma care.

Our aim is to see if a simple short messenger service (SMS) sent by the GP clinic (Banyo Clinic) increases the number of patients who attend for a planned asthma review, and as such get a current asthma action plan as part of this. To do this, we plan to design and use a computer program to search the existing general practice database and identify those patients with asthma who are eligible. Performing such a search and identification is a usual part of good practice care and clinicians regularly carry out similar audits of their databases. In this project, we additionally wish to send a SMS message to half of the population identified, inviting them to book an appointment for an asthma review. The other half of the population won’t receive an SMS and therefore will receive usual care. After two months, we will send a follow up reminder SMS to those who haven’t attended for an asthma visit with the same SMS reminder.

After data collection, we will analyse the data to see if the group who received the SMS attended at a different proportion to the control group for asthma visits and supply of action plans. Our hypothesis is that, compared to usual care in the control group, receiving an automated SMS reminder prompting patients to attend for an asthma management review will:
1: Increase the attendance at the clinic for a planned asthma review
2: Increase the proportion of patients with asthma management plans

The population target will be active patients with asthma who have attend the Banyo Clinic at least twice in the preceding two years who have a mobile phone number attached to their file. Eligible participants will be defined as those who have asthma in their active past history. Participants will be identified from the clinic's data base and recruited by mail from the clinic. It is estimated that there will be approximately 300 eligible people in both the control group and the intervention groups. The participants will be randomized by computer to either the intervention (SMS receiving group) or the control (care as usual) group.
