Final answer:
All the provided options, such as aging of the population, increases in hospital expenses, higher costs for physician services, and an increase in the number of prescriptions written, contribute to the rise in healthcare expenditures in the U.S.
Step-by-step explanation:
The question seeks to identify factors that do not contribute to the increase in health care expenditures in the U.S. Among the choices given, all options such as aging of the population, increases in hospital expenses, higher costs for physician services, and increase in the number of prescriptions written are known contributors to the rise in healthcare spending.
The aging Baby Boomer population leads to higher demand for healthcare services, resulting in increased Medicare spending. Hospital expenses and physician services costs are rising, contributing to overall healthcare costs. Moreover, the introduction of Medicare prescription benefits, while beneficial for public health, has added to the financial burden due to higher costs and inflationary effects on prescription drugs.
