Improving the Rate of Influenza Vaccination: A trial of three outreach methods.

This study examined whether mail, telephone, and direct contact could improve a family practice's immunization rate and how patients would react to the outreach strategies. Influenza immunization rates of 73.4% in patients older than 65 and 57.1% in younger patients with chronic illnesses were achieved. Almost all patients accepting immunization appreciated being notified; most preferred telephone contact.
