Insights
Parental reminder interventions, like voice calls and SMS messages, can improve childhood immunisation rates. Mobile technology, particularly SMS, is a cost-effective strategy for timely vaccination reminders.
Area of Science:
- Public Health
- Health Services Research
- Preventive Medicine
Background:
- Childhood immunisation is crucial but faces barriers globally.
- Parental reminder strategies have been developed to improve vaccination uptake.
- Systematic review of interventions and cost-effectiveness is needed.
Purpose of the Study:
- To systematically review parental reminder interventions for childhood immunisation.
- To evaluate the cost implications of these interventions.
- To assess the impact on immunisation coverage and timeliness.
Main Methods:
- Systematic review of 24 articles from five databases (Medline Complete, CINAHL, Academic Search Premier, SPORTDiscus, Health Source Nursing/Academic).
- Meta-analysis for studies with sufficient data; narrative synthesis for others.
- Inclusion criteria focused on parental reminder interventions for childhood immunisation.
Main Results:
- Low-quality evidence suggests parental voice calls improve immunisation coverage (OR 4.752).
- High-quality evidence shows Short Message Services (SMS) health education messages improve timely immunisation (OR 2.711).
- Average cost of SMS interventions was USD 0.50 per outcome.
Conclusions:
- Mobile technology, specifically SMS, is a promising strategy for improving childhood immunisation outcomes.
- SMS reminders are cost-effective and enhance timely vaccination.
- Further research may explore optimal implementation of these mobile health strategies.
Abstract:
Getting children vaccinated amidst prevailing barriers to immunisation has been challenging in both developed and developing countries. To address these problems, studies on parental reminder strategies were conducted to improve immunisation outcomes in children. These led to the development of different parental reminder interventions. This review systematically reviews different parental interventions and their cost implication for improved immunisations. Five online databases; Medline Complete, the Cumulative Index for Nursing and Allied Health Literature [CINAHL], Academic search premier, SPORTDiscus, and Health Source Nursing/Academic were searched using search terms. A total of 24 articles that met the inclusion criteria were included in this review. Studies that provided sufficient information were included for meta-analysis using Comprehensive Meta-Analysis version three, while narrative synthesis was used for the other studies. Results indicate that a heterogeneous and low-quality certainty of evidence on parental voice calls (OR 4.752, 95% CI 1.846-12.231, p = 0.001) exists in improving immunisation coverage. Regarding immunisation timeliness, a high-quality certainty of evidence on Short Message Services (SMS)-delivered health education messages (OR 2.711 95% CI 1.387-5.299, p = 0.004) had more effect on timely immunisation uptake. The average cost of SMS-delivered parental reminder interventions for improved immunisation outcomes was USD 0.50. The study concludes that mobile technology is a promising, cost-effective strategy for improved immunisation outcomes.
