Promoting Flu Vaccination Through a Mobile Wellness Program

NCT02908893 | Unknown

• 1 other identifier: EH-002
• Study Type: interventional
• Target: 77,983
• Locations: 1 country
• Sites: 1

Brief Summary

The investigators design a 6-week messaging campaign aimed at promoting flu vaccination among fully insured members of a national payer that participate in a wellness program offered by the insurer through a mobile app. Outcomes measured will include uptake in flu vaccination rate as measured by the insurer and engagement with the campaign through the app. The goal of the research is to assess the effectiveness of pervasive computing messaging in promoting preventative care treatments such as flu shots. An additional goal is that of quantifying the importance of emphasizing incentives to increase efficacy of the messages.

Conditions

Not Condition-specific

Outcome Measures

Primary Outcomes (2)

• Increase in vaccination rate vs control

  Increase in vaccination rate of anyone messaged relative to the control condition

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

• Increase in vaccination rate of salient vs non-salient

  Increase in vaccination rate of those who received salient incentives messages vs those who received generic messages

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

Secondary Outcomes (4)

• Decrease in medically attended flu events of messaged vs control

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

• Increase in reporting of flu vaccination through wellness app of salient vs non-salient

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

• Increase in vaccination rate for users messaged within 2 days before of an expected rx pick-up.

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

• Increase in message open rate of Salient vs Non-salient arm

  Up to 1 week after the end of each of the three batches of the intervention (Oct 1/15/28 2016)

Study Arms (3)

Salient

EXPERIMENTAL

Messages in the salient arm highlight the number of incentives (points) received by getting a flu shot and recording it through the wellness program app. Additionally, messages mention that flu shots can be received at the pharmacy while picking up an Rx. Users in the arm are matched up with a second user from the same arm, randomly. For each pair, the messages are sent to both users at the same time within the specified time window. Such time is picked to be the day in which the first user is most likely to pick up an Rx from a pharmacy.

Behavioral: In-app and push notification mobile messages

NonSalient

ACTIVE COMPARATOR

Messages in the non-salient arm highlight the benefits of getting vaccinated against flu, but make no mention of incentives received for getting vaccinated. Incentives would still be earned through the wellness program if the vaccination is recorded. Messages mention that flu shots can be received at the pharmacy while picking up an Rx. Users in the arm are matched up with a second user from the same arm, randomly. For each pair, the messages are sent to both users at the same time within the specified time window.

Behavioral: In-app and push notification mobile messages

Control

NO INTERVENTION

Users in this group will not receive any message promoting flu vaccination. Incentives would still be earned through the wellness program if the vaccination is recorded.

Interventions

In-app and push notification mobile messages BEHAVIORAL

Short messages (100-250 characters) are to be delivered to a mobile app both by push notification (i.e., appearing on the phone dashboard like a text message if the user has allowed notifications from the app) and in-app messages (visible in the news feed of the wellness program app when the app is opened). Messages contain a short title (30 characters) and 2-3 lines of text in the body (30 characters each).

NonSalient; Salient
