From Treatment to Prevention: The Change the Health System Needs

In the healthcare sector, we spend most of our resources treating illnesses that, in many cases, are preventable. This isn't because it's pointless to treat those who are already sick, but because the culture and systems have been built around treatment once someone is already ill, not prevention. This means we need to rethink the model from its very foundation: how healthcare products are designed, how the success of a healthcare system is measured, what technology incentivizes, and what role companies, governments, and citizens should play in building a true culture of prevention.

The traditional healthcare and insurance model has for years been a reactive model, in which the client becomes ill, files a claim, and the system reimburses. This approach has the advantage of guaranteeing financial protection against adverse events; however, it has a structural flaw: there are no inherent incentives to prevent such events from occurring.

The cost of maintaining this inertia is rising, as out-of-pocket health spending in Mexico increased by 7.9% in real terms between 2022 and 2024, reaching an average of US$6,421 MXN annually per household.[1] For insurers, the financial argument is equally compelling, since a person arriving at the emergency room, for example, in a hypertensive crisis, generates exponentially higher costs than someone who receives monthly blood pressure monitoring. A stage IV cancer diagnosis costs, in time, resources, and human capital, much more than it would have cost to detect it at stage I; in other words, the reactive model is not only inefficient, it is also the most expensive of all.

The Benefits of Prevention

Talking about prevention as a strategy implies taking a long-term perspective that is not always comfortable in the business world, since the results of prevention are not seen in the next quarter, they can take up to years, reflecting in the sustained productivity of organizations and in the quality of life of people, and that does not make them any less real or less measurable.

From an economic standpoint, timely preventative intervention significantly reduces treatment costs. For example, detecting an employee in the prediabetic stage and supporting them with lifestyle changes, nutritional follow-up, and digital monitoring costs a fraction of what it will cost to treat their established diabetes, with all its associated renal, cardiovascular, and ophthalmological complications. For a finance director, this difference translates directly into the cost of claims at the end of the fiscal year.

The social benefits are equally significant: prevention reduces absenteeism, extends the population's productive years, lessens the burden on hospitals and public systems, and generates a more rational and predictable demand for health services. A prevention-oriented system is cheaper and fairer, as it intercepts disease before it drags individuals and their families into economic vulnerability.

Technology, Data: Enabling Predictive Medicine

What truly sets today's prevention apart from what we knew ten years ago is access to real-time data and the capabilities of artificial intelligence, which, combined with a human team, can transform that data into actionable early warnings. We are moving beyond the annual checkup as the sole preventative measure, towards continuous monitoring that converts everyday physiological information into early diagnosis.

Wearable devices, such as smartwatches and AI-enabled monitors, can now detect cardiac arrhythmias, glucose levels, disrupted sleep patterns, and early signs of neurodegenerative conditions with an accuracy that previously required hospital equipment. In Mexico, 46.74 million users of these devices are projected by 2029,[2] indicating that preventative monitoring infrastructure is reaching a massive scale.

Artificial Intelligence adds to this the ability to analyze entire populations to identify risk patterns before they manifest clinically. For insurers, this opens up a transformative possibility: to stop managing policies and start managing health trajectories. With the insured's consent and adequate data protection, it is possible to design personalized interventions, activate early clinical alerts, and adjust service offerings in real time according to each person's risk profile. The policy ceases to be a piece of paper that is activated when something goes wrong and becomes an active partner in the health of the policyholder.

Triple Role: Businesses, Governments, Citizens

Prevention cannot be the sole responsibility of the health sector; it is an agenda that requires the coordinated participation of three actors who currently operate with too much independence from one another. In this regard, companies have a privileged role, since their employees spend most of their productive time within their work environments, and the conditions they create are risk factors directly linked to chronic diseases. Incorporating preventative wellness programs is not corporate philanthropy; it is strategic human capital management. This is especially important considering that seven out of ten employees in Mexico have experienced some type of burnout,[3] with direct consequences for productivity, turnover, and organizational health costs. Therefore, companies that invest in detecting and addressing the risk before it escalates see measurable results across all these indicators.

Governments, for their part, have the responsibility to create regulations that reward prevention, early detection programs accessible to the entire population, and public policies that reduce environmental and social risk factors. Finally, citizens: the most sophisticated prevention in the world fails if people do not actively participate in their own care. Building a culture of prevention involves reducing barriers to access, communicating clearly and without paternalism, and designing experiences that make self-care easier than neglecting it.

The shift from a reactive to a preventive model is a business decision, and it is also an ethical one; a health sector that continues to measure its success in the number of claims handled, instead of in the reduction of adverse events, is optimizing the wrong metric. The health system in Mexico has a historic opportunity before it: to use the available technology, the urgency of the data, and the convergence of actors to make the structural leap that has been pending for decades; therefore, prevention is not only a smarter strategy, it is the only one that truly puts the patient at the center of everything we do.
