In 1999, Medicare implemented a resource-based relative value unit (RVU) system for physician practice expense payments, and increased the number of services for which practice expense payments differ by site. Using 1998-2004 data, we examined RVU growth and decomposed that growth into resource-based RVUs, site of service, and service quantity and mix. We found that the number services with sit...

In this important work, we discuss some novel Hilbert-type dynamic inequalities on time scales. The investigated here generalize several known scales and unify extend continuous their corresponding discrete analogues. Our results will be proved by using algebraic inequalities, Hölder inequality, Jensen’s inequality

Risk management includes identifying risks, assessing risks either quantitatively or qualitatively, choosing the appropriate method for handling risks, and then monitoring and documenting risks. By identifying risks in an early stage of planning and assessing their relative...
