Summary
Written by AI, not yet AICS's view · claude-sonnet-5-5The study tested whether automated Google Calendar reminders help mothers keep to the basic immunization schedule for their infants in Grogol, Kediri Regency, Indonesia. Sixty mothers of infants aged 0-9 months were split into a reminder group and a control group receiving routine services. Compliance rose from 46.7% to 83.3% in the reminder group, and from 36.7% to 46.7% in the control group, a rise that was not statistically significant. After the intervention, the reminder group had significantly higher compliance than the control group. The authors conclude that this simple digital tool could support immunization services in primary health care.
Key points
- Basic immunization coverage in the Grogol Primary Health Center area has not reached the national target.
- Compliance in the reminder group rose from 46.7% to 83.3% (p=0.013).
- Compliance in the control group rose from 36.7% to 46.7%, which was not significant (p=0.250).
- Post-test compliance was significantly higher in the reminder group than in the control group (p=0.003).
- The authors say timely automated notifications are a simple digital way to support immunization services.
Limitations
The sample was small (60 mothers), drawn purposively from one health center area, and the control group started at a lower baseline compliance level. The abstract does not report follow-up beyond the post-test or whether actual coverage in the wider population changed.
Abstract
Basic immunization coverage in the working area of Grogol Primary Health Center has not yet reached the national target, highlighting the need for effective strategies to improve maternal compliance with childhood immunization schedules. This study aimed to analyze the effect of a Google Calendar–based immunization reminder on maternal compliance with the basic immunization schedule for infants. A quasi-experimental study with a pretest–posttest control group design was conducted among 60 mothers of infants aged 0–9 months, selected using purposive sampling. Participants were assigned to an intervention group (n=30), which received Google Calendar–based immunization reminders, or a control group (n=30), which received routine immunization services. Compliance was assessed using the Maternal and Child Health (MCH) Handbook observation sheet and a Guttman-scale questionnaire. Data were analyzed using the McNemar and Chi-square tests, with a significance level of p<0.05. Compliance in the intervention group increased from 46.7% at baseline to 83.3% after the intervention (p=0.013), whereas the control group showed a non-significant increase from 36.7% to 46.7% (p=0.250). Post-test comparison demonstrated significantly higher compliance in the intervention group than in the control group (p=0.003). Google Calendar–based reminders effectively improved maternal compliance with the infant basic immunization schedule by providing timely automated notifications. This simple digital intervention has the potential to support immunization services and enhance immunization coverage in primary healthcare settings.
