Text messages increase influenza
vaccination rate at low cost
Short message service (SMS) text reminders appear to
increase the influenza vaccination rate at low cost in
Australia, according to findings of a study published in
Annals of Family Medicine.
During May 2016, 12 354 high-risk patients eligible
for seasonal influenza vaccination at ten medical
practices in Western Australia were randomised to
receive an SMS reminder or no reminder; subsequent
vaccination data was obtained from their electronic
medical records three months later.
Overall, the vaccination rate was higher in patients
who received an SMS reminder than in the control group
(12% vs 9%; relative risk [RR] 1.39; 95% CI 1.26 1.54).
One additional patient was vaccinated for every 29 SMS
reminders sent, at a total cost of $3.48.
Text reminders were most effective when reminding
parents to vaccinate children under 5 years of age
(RR 2.43; 95% CI 1.79, 3.29). However, text reminders
had no significant effect on influenza vaccination rates in
pregnant women, non-pregnant women 18
44 years of
age, or Indigenous patients.
"We found SMS reminders to be a modestly effective,
low-cost means to increase seasonal influenza vaccine
coverage among high-risk patients," said the authors.
