Brief Summary
Influenza disease causes significant morbidity and mortality in the Unites States each year. Although influenza can cause morbidity in otherwise healthy individuals, adults with chronic lung disease have significantly increased rates of hospitalization from influenza-related illnesses compared to healthy adults. Influenza vaccination is the primary means of preventing influenza disease. Annual influenza vaccination is recommended for all individuals 6 months of age and older in the United States. Influenza vaccination rates are sub-optimal, however. Patient reminder/recall has been shown, in multiple studies across a variety of age groups and health conditions, to increase immunization rates. However, the effectiveness and cost-effectiveness of different types of reminder/recall has not been well-studied, particularly in adults. In the fall of 2012, the Population and Prevention Services (PPS) Department at Kaiser Permanente Colorado (KPCO) is using 3 different reminder strategies for influenza vaccination among adults with asthma and chronic obstructive pulmonary disease (COPD). The objective of this study is to provide a rigorous evaluation of which strategy is more effective and more cost-effective, to promote influenza vaccination.

Study Arms (3)
Postcard Only Reminder Group
ACTIVE COMPARATORIn the postcard reminder intervention, the member will receive a single postcard, addressed to the member with asthma or COPD.
IVR Only Reminder Group
ACTIVE COMPARATORIn the IVR reminder intervention, targeted members will be contacted by the interactive voice response system
Postcard and IVR Reminder Group
ACTIVE COMPARATORIn this group, individuals will receive both a postcard reminder and an IVR reminder.
Interventions
IVR: Subjects in this reminder group will receive an automated telephone call to their primary telephone number. A total of 2 call attempts per member will be made. The IVR system will provide a message about the importance of annual influenza vaccination. The member can also request additional information about influenza vaccination and influenza vaccination locations and times. Postcard: The postcard will be sent as a single postcard to each individual on the list. The postcard will be sent to the home address of the member. If the postcard is returned, the postcard will not be re-sent. The postcard does not identify that the member has a chronic health condition such as asthma or COPD. The postcard will be mailed during the last two weeks of September, 2012.
Postcard: The postcard will be sent as a single postcard to each individual on the list. The postcard will be sent to the home address of the member. If the postcard is returned, due to an inaccurate address, the postcard will not be re-sent. The postcard does not identify that the member has a chronic health condition such as asthma or COPD. The postcard will be mailed during the last two weeks of September, 2012.
