About

Influenza morbidity and mortality cause a substantial financial burden to the NHS and to the UK as a whole. Influenza vaccine is safe and effective but is required annually because the circulating strain of virus changes each year. In the UK in 2012, the Chief Medical Officer (CMO) recommended that at least 75% of elderly people (aged 65+) and 75% people under 65 with certain chronic conditions (e.g. chronic heart disease, diabetes, asthma, etc) should be vaccinated. While primary care practices are achieving these targets for elderly patients, those set for younger patients with chronic conditions are not being met, with a third of patients being missed in the 2011/12 flu season and with no substantial improvements in uptake in the past decade. Therefore strategies to increase flu vaccine uptake in these patients are required.

Previous trials have shown that patient reminders can increase vaccine uptake and in particular, text messaging has shown to work in some populations in the United States as a cheap, simple and effective reminder. However, whether the same is true in UK general practice is unclear. The use of text messaging in the NHS for appointment reminders is also increasing as it is cheap, quick and effective. Text messaging is already used in roughly 30% of practices to remind patients about their flu vaccine but there has been no trial addressing its effectiveness. Therefore, we propose a trial of a text messaging flu vaccine reminder in patients aged under 65 who have a chronic condition. We hypothesise that practices that send a text message will have increased flu vaccine uptake.
