Systems and methods are provided for monitoring members of a group and providing coordinated care of the members. Monitoring devices are provided to each of the members which may take periodic health measurements of the member. The health measurement is compared to intervention criteria, which when satisfied, cause one or more interventions to be provided, such as a message sent to a member, a message sent to a health care provider or other interested individual, medical care provided to the member, or other intervention. Monitoring devices may be provided on a subscription basis. Group membership can be dynamic and based on a member's current health measurements. Health measurement information may be provided in reports.
