The Care EngineSM Service of HealthEOS reduces medical errors and associated costs. That alone justifies its modest cost as an integrated component of the HealthEOS Plan. However, in addition to avoiding the adverse cost of medical errors, simply improving healthcare quality itself reduces future healthcare costs.

Furthermore, the CareEngineSM Service Economic Model proves that as a population grows older health care costs increase. Employee demographics impact the ROI of the CareEngineSM Service. The following table illustrates the ROI on a per member per month basis for the HealthEOS CareEngineSM Service study populations shown here. The Care EngineSM Service is available for a fee of $1.60 pmpm (member equals gross lives). That fee includes the Disease Management/Disease Identifier and the Doctor Messaging, which assures maximum communication for CareEngineSM Service recommendations. The Four-Year ROI assumes CareEngineSM Service fees are only paid in the first year and reflects the continuing impact over the first four years.
