Abstract:
A randomized controlled trial was undertaken to measure the efficacy of a patient reminder system for females age 40 - 75 in a Midwestern primary care practice. A subset of the population whose email addresses were known was further randomized to measure the effect of email versus postal reminders. A statistically significant increase in completion rates was observed in the intervention group while no difference was found between the email and postal mail groups.
