Healthcare Can’t Afford to Wait Until People Get Sick

Why prevention may be the best investment the healthcare system can make.

The United States doesn’t have a healthcare spending problem because people are getting too much care. It has a healthcare spending problem because too much of that care begins only after people become sick.

Every day, our healthcare system performs extraordinary work treating heart attacks, managing diabetes, replacing worn joints, controlling chronic pain, and helping patients recover from serious illness. Those advances have extended lives and improved countless outcomes. But they also reveal an uncomfortable truth: much of what we spend on healthcare is devoted to managing diseases that, in many cases, could have been delayed, minimized, or even avoided altogether.

As healthcare costs continue to rise, the question is no longer whether prevention matters. It’s whether we can afford to keep treating prevention as an afterthought.

The Economics Are Hard to Ignore

The Centers for Disease Control and Prevention estimates that 90% of the nation’s $5.3 trillion in annual healthcare expenditures are spent caring for people with chronic and mental health conditions (Centers for Disease Control and Prevention).

Many of these conditions—including heart disease, Type 2 diabetes, obesity, hypertension, chronic respiratory disease, and many forms of chronic pain—develop gradually over years. They are influenced by a combination of lifestyle, environmental, behavioral, and social factors that often begin decades before a diagnosis is made. All too often, by the time a patient requires surgery, multiple medications, or repeated hospitalizations, the most cost-effective opportunity to improve health has already passed.

From an economic perspective, healthcare has become highly efficient at financing illness, but far less effective at investing in health.

Fortunately, that equation is beginning to change. As healthcare continues shifting toward value-based care—rewarding better outcomes rather than a greater volume of services—prevention is becoming both a clinical priority and a financial one.

Prevention Delivers Returns—Not Just Better Outcomes

Prevention is sometimes portrayed as an idealistic goal—but, in reality, it is one of the most practical financial strategies available to healthcare systems.

The World Health Organization reports that every $1 invested in proven interventions to prevent noncommunicable diseases can generate approximately $7 in economic returns through improved productivity, reduced healthcare costs, and longer, healthier lives (World Health Organization).

The CDC likewise notes that evidence-based interventions—such as tobacco cessation, hypertension management, diabetes prevention, cancer screening, and increased physical activity—improve health while reducing long-term healthcare expenditures (Centers for Disease Control and Prevention).

In nearly every other industry, leaders ask how to reduce costs by preventing problems before they occur. Increasingly, healthcare is beginning to do the same.

Prevention Means More Than Annual Screenings

Preventive care certainly includes annual physicals, vaccinations, cancer screenings, and routine laboratory testing. But the levers of prevention are much broader than that. Research continues to demonstrate that many of the strongest predictors of long-term health include:

• Nutrition
• Physical activity
• Sleep quality
• Mental and emotional well-being
• Stress management
• Social connection
• Tobacco and alcohol use
• Purpose and meaning in life

In fact, the CDC identifies poor nutrition, physical inactivity, tobacco use, and excessive alcohol consumption as the leading modifiable risk factors behind many chronic diseases (Centers for Disease Control and Prevention ).

These aren’t simply lifestyle choices. They are among the most significant drivers of both health outcomes and healthcare spending.

A Different Way to Think About Healthcare

If healthcare is going to place greater emphasis on prevention and long-term outcomes, clinicians must be trained to think differently about health itself—not simply as the absence of disease, but as the foundation for living a meaningful, fulfilling life.

At Southern California University of Health Sciences (SCU), that philosophy is reflected in the university’s Whole Health approach. Rather than teaching students to ask only, “What disease or condition does this person have?” they also learn to ask, “What matters most to this person, and what factors are influencing their overall health and well-being?”

“The future of healthcare isn’t simply treating disease more effectively—it’s helping people remain healthier and happier for longer,” says Michael Ramcharan, MD, MPH, DC, EdD, and Vice Provost and AVP of Academic Affairs at Southern California University of Health Sciences. “When we address nutrition, movement, sleep, mental health, social connection, and purpose alongside clinical care, we’re not just keeping people symptom-free. We’re changing the trajectory of their lives.”

In other words, Whole Health does not replace evidence-based medicine; it simply broadens the lens through which evidence is applied. Medications, surgery, rehabilitation, behavioral health, nutrition, physical therapy, chiropractic care, acupuncture, occupational therapy, lifestyle medicine, and health coaching all have a role to play. But the evidence suggests that they work best when they work together to support the whole person.

Preparing the Workforce Healthcare Needs

This shift has implications far beyond patient care. It changes how we educate healthcare professionals.

Tomorrow’s clinicians will need to understand disease prevention as well as disease treatment. They will need to collaborate across professions, recognize the social and behavioral drivers of health, and help patients make sustainable changes—not simply respond once those changes are no longer possible.

“Healthcare is shifting toward proactive longevity rather than reactive treatment,” says Dr. Ramcharan. “We must equip graduates with deep knowledge of human physiology and the science of healthy aging, so they can help people and communities extend not just lifespan, but healthspan.”

That preparation is already underway at SCU, where students learn to integrate prevention, patient-centered care, and interprofessional collaboration into clinical decision-making. As healthcare increasingly emphasizes value over volume, these competencies will become essential—not only for improving patient outcomes, but also for creating a more sustainable healthcare system.

The Best Healthcare Is the Care That Never Becomes Necessary

America will always need exceptional hospitals, groundbreaking therapies, and highly skilled clinicians. But those investments alone cannot bend the curve of chronic disease or rising healthcare costs.

To do that, we must become just as committed to investing in health as we are to treating illness.

The healthcare system of the future will still save lives in emergency rooms and operating rooms. Its greatest achievement, however, may be the lives that never reach those places because risk was recognized early, healthy behaviors were supported, and care focused on the whole person—not simply the disease.

Ultimately, the future of healthcare will be measured not only by how well we treat disease, but by how often we prevent it. That is an investment our healthcare system can no longer afford to postpone.
