What this trial studies

This clinical trial evaluates how effective telephone text message reminders from general practitioners (GPs) are in increasing influenza vaccination rates among patients aged 65 and older. The study involves 22 GPs who will be randomly assigned to either send reminders or provide usual care, with each GP including up to 210 eligible patients. The trial aims to determine if the reminder can achieve a 4 percentage point increase in vaccination rates compared to the control group by the end of the vaccination campaign.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 65 and older who are patients of participating GPs in the Ile-de-France region.

Not a fit: Patients receiving palliative care or those deemed inappropriate for participation by their physicians may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve influenza vaccination rates among older adults, enhancing their protection against the virus.

How similar studies have performed: Previous studies have shown that reminder systems can effectively increase vaccination rates, suggesting this approach may yield positive results.
