Objectives. This study evaluated the effectiveness of an annual public heal
th intervention in a managed care setting.
Methods. Managed care organization members 65 years and older who received
influenza immunization in 1996 were randomized to an intervention group (ma
iled a postcard reminder to receive an influenza vaccination in 1997) or a
control group (no postcard). Vaccination rates for both groups were assesse
d monthly.
Results. Members receiving the intervention were no more likely to be immun
ized (78.6%) than members of the control group (77.2%, P = .222). Members w
ere vaccinated at the same pace regardless of vaccination history and postc
ard intervention status.
Conclusions. Postcard reminders were not an effective intervention among se
niors who had been vaccinated the previous year.
