Private health insurance companies and the Centers for Medicare and Medicaid Services (CMS) insure more than 90% of Americans (about 9% of Americans are uninsured). They set plan prices and premiums based on two main factors: total costs for covered services and utilization rates.
In the last two decades, Americans have seen their portion of health care premiums rise by 272% for individual coverage and 243% for family coverage (employers are paying over 200% more, too). Year-over-year increases are sometimes double-digit percentages, which can place undue burdens on families with tight budgets. Premiums for Medicare and Medicare Advantage plans for Americans over 65 also go up as costs and utilization rise.
Unfortunately, this trend isn’t likely to reverse in the near future. The reason: Both parts of the premium equation — health care resource utilization and costs — are likely to remain high.
A report from the National Academy of Sciences, Engineering, and Medicine Committee on Health Care Utilization and the Social Security Administration looked at the factors influencing use of health care services. Utilization, as defined in this report, is the use of “health care services to diagnose, cure, or ameliorate disease or injury; to improve or maintain function; or to obtain information about their health status and prognosis.”
Health care utilization in the U.S. is steadily trending upward. The primary reasons for the increase include:
The Affordable Care Act aims to reduce the total cost of care in the U.S. and improve patient outcomes. CMS has introduced several cost-saving and quality improvement initiatives, broadly termed “value-based care” (VBC).
In the long run, VBC efforts will hopefully produce significant cost savings by:
In the short term, VBC emphasis on that third part — preventive care — is increasing the volume of health care services people need. More patients have health coverage than before the law was passed, which means more are going to their primary care doctors and/or seeking specialty care.
Widespread use of preventive care should eventually lower total costs by minimizing high-cost care in emergency rooms or hospitals, but in the short term it has the opposite effect on insurance beneficiary costs. When utilization rates go up, health insurance costs also go up.
As people age, they require more health care. People 65 and older make up about 17% of the U.S. population, but account for about 35% of all health care spending. If you include people ages 45 and up, 43% of the population is spending 70% of all health care dollars.
About 10,000 baby boomers are reaching Medicare age (65) every day in the U.S. right now. In less than 10 years, the entire generation will be over 65. Higher utilization is generally not a choice for this population, it's a necessity. With medical innovations that prolong the length and quality of life, that generation is likely to be utilizing more health care for several decades to come.
Four in 10 Americans have one chronic condition, and more than half of them have two or more. When you include mental health, people with chronic health conditions account for about 90% of all health care spending. Part of the reason for that higher spending is higher inpatient and outpatient utilization compared to patients with no chronic conditions. We discuss the implications of chronic disease management on health care costs in more detail in Part 4 of this blog series.
The U.S. health care system is often recognized as one of the most innovative and advanced in the world. The World Index of Healthcare Innovation ranks America fourth, behind only Switzerland, Germany, and the Netherlands. Patients in the U.S. have some of the earliest access to new therapies, surgical innovations, and new medications or drug therapies.
Innovation presents a challenge for health insurance providers, however, because leading-edge treatments cost more. Advanced procedures, tests, and imaging may require costly technology or care in large academic medical centers. Breakthrough treatments for devastating diseases like cancer require expensive and ongoing treatment with equipment that may only be available at limited sites throughout the country.
New medications for increasingly complex health conditions can improve quality of life, lengthen the course of diseases, or even cure a patient. But covering pharmaceutical research and development, production, operations, and marketing comes with a high price tag.
Another focus of many public health experts, providers, and insurance companies is the impact of health care access and social determinants of health on total care utilization and costs.
Patients with limited access to health care services may not get the preventive and ongoing care they need. When they do seek medical attention, it’s more likely to be through high-cost touch points like emergency rooms and hospitals. Lower-income individuals are about 2.5 times more likely to visit an emergency department for a preventable reason than someone with higher income. Patients who live in rural communities and have to drive long distances to get the care they need may also delay seeing a doctor until their health worsens and they require more expensive care.
Innovations such as telemedicine that can remove some of these barriers and lower health care costs are only available to people with reliable broadband service. Over 6% of the population (21 million people) lacks access to broadband services. The majority (14.5 million) live in rural communities. Such services will not have a significant impact on health care costs until they are widely available to all patients.
There isn’t much we can do to change the demographics of an aging population. Nor are there short-term fixes for things like limited access to care and high rates of chronic disease. But there are steps we can take to address high utilization and help push overall costs down.
For example, employers can help patients understand when to seek care in an emergency room and when urgent care is a better option. Care management programs and services provide another touch point for high-utilization, high-cost patients. These programs help people effectively manage their care to avoid emergency rooms, hospital admission, and disease progression as much as possible.
Offering wellness programs to beneficiaries can also improve overall health, reduce the risk of chronic disease, or better manage existing conditions. While that alone won’t solve the health care crisis, many small changes can help move the needle in the right direction.
Utilization is just one piece of a large and complex puzzle of high costs in health care. In this series, we look at several other things contributing to high costs in more detail. We also look at ways Highmark Health and our partners are trying to address each of these aspects of care.
