Effectiveness of text message reminders on paediatric appointment adherence: a systematic review and meta-analysis

Attending health appointments is important for the paediatric population, as it allows for earlier detection of health issues and subsequent necessary treatments. It also ensures timely immunisations while also allowing patients or their parents to raise health concerns. Hence, it is crucial to take steps to ensure that such medical appointments are attended. To evaluate the effectiveness of text message reminders (TMRs) in improving paediatric patients' adherence to their appointments. A systematic review and meta-analysis were conducted. The search spanned across eight online databases from their inception dates to January 2024. The random-effects model was utilised to conduct the meta-analysis, where risk ratio was used as the effect measure. Subgroup analyses were conducted for age, number of TMRs sent, and type of appointments attended. In total, 13 studies were included. Compared to standard care (involving non-text message reminders or no reminders), TMRs were significantly more effective in improving appointment attendance among the paediatric population. Significant subgroup differences were found in the type of appointments attended, where TMRs were more effective for medical appointments compared to vaccination appointments. No differences in adherence to appointments were found across age groups or the number of TMRs sent.   Conclusion: Sending TMRs can be a potentially cost-effective way to improve the attendance rate of paediatric medical appointments, given the ease of implementation and the extensive mobile phone usage globally. Future studies should compare TMRs to other modes of automated reminders such as telephone messages or emails, to identify the most optimal method of delivery.   Trial registration: PROSPERO (CRD42023464893).
