The most effective interventions are often the least glamorous

A recent study from the flagship journal of the American Cancer Society estimates that, since 1970, nearly 4 million deaths have been prevented through tobacco control measures such as cigarette taxes and anti-smoking campaigns. These numbers offer a stark reminder that system-level public health measures can yield results on a scale far exceeding what clinicians might achieve.

In clinical practice, even the most dedicated doctor might treat around 100,000 patients over a career, significantly impacting only a fraction of these lives. Yet a single policy change, like increased cigarette taxes, has been shown here to prevent millions of deaths. This comparison isn’t meant to diminish the essential work of clinical medicine. Rather, it highlights how policy interventions can multiply the benefits that individualized care provides.

If it’s so impactful, why is the United States significantly behind in the realm of public health and health policy? Part of the reason these measures are so hard to implement is the substantial initial investment required, combined with a return on that investment that may not be realized for decades. The benefits of tobacco control, for instance, have been gradually unfolding over a long timeframe. Politicians, who are up for reelection every few years, can have a tough time justifying the immediate costs. Older generations, who hold a substantial portion of the country’s wealth and power, may be especially unmotivated to shoulder these costs when the rewards will only manifest much later in the future.

Another obstacle is rooted in America’s longstanding values of freedom and individualism. Measures perceived to limit personal choice, such as cigarette taxes, often encounter resistance from those who argue that it isn’t the government’s role to influence individual behavior. How do we balance this with the undeniable health (and economic) benefits of such a policy? This debate continues to simmer, as seen in ongoing discussions over sugar-sweetened beverage taxes.

Ultimately, while the work of clinicians remains indispensable, we like to remind people that the magnitude of clinician impact is dwarfed by system-level changes. The challenge isn’t choosing between clinical medicine and public health; it’s about recognizing that our greatest leaps in health improvement often come from public health measures and policies. As a society, we must decide to what extent we’re willing to sacrifice individual choices for the sake of substantial health and economic gains. Embracing interventions that may not be flashy, but save millions of lives over time, is critical as we work to craft a healthier future.
