Researchers at the Mailman School of Public Health and Columbia University Medical Centre studied the impact of text message reminders for the second dose of influenza vaccine required for many young children to protect them against the virus.
The findings showed that sending text message reminders both increased receipt of the second dose of the vaccine by the end of the season as well as brought children in sooner to be vaccinated.
When educational information on the importance of the second dose of influenza vaccine was embedded into the text messages there was an even greater effect compared both with conventional text messages that only told families when and where to go as well as with written reminder only.
Children in 660 families were in need of a second dose of influenza vaccine that season took part in the intervention. Most families were Latino and publicly-insured; nearly three-quarters (71.9 per cent) thought that their child was at least somewhat protected from influenza after one dose.
The children who ranged in age from 6 months through 8 years old were assigned into one of three groups: "educational" text message, "conventional" text message, and "written reminder-only" arms.
All families had a cellphone with text messaging capabilities. A written reminder with next dose due date was given at the time of the child's first influenza vaccination to all families.
"Text message programmes like these allow for healthcare providers to care for their patients even when they are not in front of them in the office, somewhat like a modern day house call," said Melissa Stockwell, principal investigator.
Parents reported liking the text messages and saw them as helpful because they acted as a reminder, provided information in a quick way that did not require talking with anyone, and demonstrated someone "cared."
The research was published in the journal Pediatrics.
