text4peds: a randomised text-messaging trial

BACKGROUND: The use of cell phone text messaging in the medical field is of growing interest, but there are few data examining its value in medical education. The text4peds educational text-messaging program was created for third-year medical students preparing for the National Board of Medical Examiners (NBME) paediatric subject examination. METHODS: A randomised, controlled trial was conducted with third-year medical students on their paediatric clerkship. Students in the intervention group received daily messages consisting of multiple-choice questions with links to online material. The control group received no text messages. The impact of the intervention was assessed by examining the participants' NBME examination scores and by participant surveys. RESULTS: A total of 162 students participated in the study. There was no statistical difference between the two groups, with the texting group having a mean score of 77.7 and with the non-texting group having a mean score of 77.8 on the NBME. Subgroup analysis examining the effect of anticipated specialty and online material interaction also failed to find any statistically significant difference. Students reported satisfaction with the program, with 84% rating the text messages as helpful. The students rated their participation as high, with 92% saying that they looked at the messages more than 60% of the time. Among those who received text messages, 90% would recommend the program to others. There was no statistical difference between the two group CONCLUSION: A text-messaging-based educational tool had a perceived positive educational value for medical students. This study failed to show any statistically significant impact on NBME examination scores from the text-messaging intervention.
