By using economic-value-added (EVA) and corporate value creation as the objective of AVFM, custom value deviating rate, capital cost deviating rate, cash-flow-out per purchase deviating rate and cash-flow-in per sell deviating rate are developed to be the key responding variates for AVFM, and they also decide the rational quantity range for AVFM tactics. Method for rational AVFM tactics solution could be got by means of redesigning activity information process on integrated ERP.展开更多

TEISBERG which has been modified for implementation over the last seventeen years. This new program is paid by Commercial Health Insurers (Insurance Companies) and Centers for Medicare and Medicaid Services (Medicare). This program incorporates the patients, doctors, Life Sciences Companies, Insurance Companies, Holistic practice, traditional Chinese medicine, etc. with alternative traditional treatments and therapies for Real-World Evidence based and value-based treatment customized to patients’ needs and the patients benefit. Methods: The program was proposed to achieve value for patients and an improved healthcare system which is especially needed to provide treatment for patients in Serious or Life-threatening conditions or diseases. The program will accurately measure the outcomes of patients and provide a wider choice of treatments that matter to patients, also to measure the cost that successful alternative treatments provide which may lower the cost to Medicare and Insurance Companies. Conclusion: The proposed and now implemented program is to achieve value for patients. Golden Sunrise Nutraceutical (Golden Sunrise) provides a New Medical Innovation and treatment alternative to patients suffering from Serious or Life-threatening illnesses. By using Golden Sunrise Innovation and with the incorporation of Value-based Care patients will become the drivers or it could be said the patient Ambassadors of their own health. By incorporating Golden Sunrise Innovation, the doctors will have more diversity of treatments available for their patients. Payment should reflect value not volume, and the New Medical Innovation Golden Sunrise offers will help in reducing the costs to Insurance Companies accelerating the adoption of Value-Based Care.展开更多
