Impact on Influenza Vaccination Rates of a Telephone Text Message Recall From the Attending Physician - a Cluster Randomized, Controlled and Pragmatic Trial
Impact on Influenza Vaccination Rates of a Telephone Text Message Recall From the Attending Physician - a Cluster Randomized, Controlled and Pragmatic Trial
This study is a clinical trial designed to assess the impact on influenza vaccination rates among people aged over 65 of a telephone text message recalling them to be vaccinated by their GP. Twenty-two GPs will be randomly selected in each arm (recall versus usual care, 1:1). Each GP will include a maximum of 210 patients by random selection from their patient list. A difference of 4 percentage points is expected between the two arms at the end vaccination campaign in the vaccination rate.
This is an open-label trial with 2 arms: an interventional or "recall" arm and a "usual care" or control arm. Cluster randomization at the physician level was chosen to avoid contamination within the same patients group. Physicians will be randomized at the start of the vaccination campaign in one of the two arms (1:1), and all patients eligible (with a maximum of 210 per doctor) to be vaccinated will be recalled or not, depending on their GPs arm.
