Overview of the company, current scenario and the future.

Healthcare in the USA is going through a serious crisis. The spending of the USA on healthcare is 2X per capita than other industrialized nations. Medical bills are a major factor in more in more than 60% of the personal bankruptcies in the

USA, 75% have health insurance. Between 2000 and 2006 health insurance premiums rose 87% and the average wages rose by

3.8%. In spite of this the USA ranks 37th in healthcare system. The fully insured plans are expensive and hence one of the reason for the crisis in healthcare

economy. The alternative to fully insured plan is the self-insured plan. In this, the employer retains a

portion of the risk and instead of large premiums the employer pays the administrative bills and stop loss company’s bills which are generally much lower than the monthly premium of fully insured.

Healthcare self-insurance and consulting Group offer customers with variety of services to our clients. We encourage many wellness activities, promote self-management through healthcare Apps and increased patient clinician interaction. Providing such services requires building an IT infrastructure and systems which can support huge volume of customers.

In this document we have designed an ERD to capture the requirements of the back end. Design a system such that it can queried to get all kinds of data. Our system is wellness tracking system and we capture all kinds of health metrics before wellness activity and after wellness activity, feedback, wellness activity team participation etc. These metrics are captured to analyze and make decisions on the success of wellness activities.
