Medical aid must do more than extend lifespan – it must extend healthspan

We are living longer than any generation before us. That is an undeniable success story of modern medicine.

Yet a more important question is emerging – one that has significant implications for individuals, employers and the healthcare system alike: are we living those extra years in good health?

The distinction between lifespan and healthspan is becoming increasingly relevant in global healthcare discourse. Lifespan refers to the number of years a person lives. Healthspan, by contrast, refers to the number of those years lived in good health, free from chronic disease and disability.

The gap between the two is where the real challenge lies.

Research indicates that while life expectancy has increased significantly over the past century, many people spend nearly a decade of their later years managing chronic illness. This growing “healthspan gap” is not only a personal concern; it is an economic and societal one.

The success – and limitation – of modern healthcare
There is no question that advances in healthcare have extended lifespan. Access to quality medical care, including hospitals, specialists, modern medication and procedures, has fundamentally changed outcomes for conditions that were once fatal.

Medical schemes have played a central role in enabling this access. For millions of South Africans, membership translates directly into earlier diagnosis, better treatment options, and improved survival rates.

However, extending life is not the same as enhancing its quality.

Healthcare systems, including funding models, have historically been structured around treating illness rather than preventing it. As a result, we have become highly effective at managing disease—but less effective at delaying its onset.

The strategic role of medical schemes
This is where medical schemes have a far more strategic role to play.

Beyond funding acute care, schemes are uniquely positioned to influence health outcomes across the entire continuum of care –from prevention and early detection to chronic disease management and long-term wellbeing.

Preventive screenings, primary healthcare access, mental health support, and structured disease management programmes that are personalised are not peripheral benefits. They are central to extending healthspan.

The earlier a condition is detected and managed, the greater the likelihood of preserving quality of life over time. Conversely, late intervention often results in prolonged periods of reduced functionality, increased healthcare utilisation, and higher costs. Inf act, according to the World Health Organization, depression and anxiety cost the global economy an estimated R16 trillion in lost productivity every year. In South Africa alone, workplace stress and burnout are believed to cost the economy around R160 billion annually.

A necessary shift: from reactive to proactive
Closing the healthspan gap requires a fundamental shift in how healthcare is approached.

A reactive model – where intervention occurs only after diagnosis – is no longer sufficient in the context of an ageing population and rising chronic disease burden.

A proactive model, focused on prevention and personalised risk management, is essential. This includes understanding the determinants of poor health and wellbeing, creating transparency and solutions that enable it to be effectively addressed through consumer ownership and participation.

The economic reality
The implications extend beyond the healthcare sector.
As people remain in the workforce for longer, the relationship between healthspan and productivity becomes increasingly important. A workforce that lives longer but spends more years in poor health presents a direct challenge to employers, insurers and the broader economy.

Conversely, extending healthspan supports sustained productivity, reduces absenteeism, and enables individuals to remain economically active for longer.

However, poor health does not only result in absenteeism. It also contributes to the often-overlooked issue of workplace presenteeism — where employees come to work despite being unwell, whether physically or mentally. Unlike absenteeism, which is visible and easy to track, presenteeism often goes unnoticed, yet it can significantly impact individual health, team productivity, and overall organisational wellbeing.

Redefining success in healthcare
The real measure of success in modern healthcare should no longer be lifespan alone.

It should be the extent to which those additional years are lived with independence, functionality and dignity.

Medical schemes have already played a critical role in extending life. The next frontier is ensuring that those added years are lived well.

That requires a deliberate shift – from funding illness to enabling health.

Because ultimately, the objective is not simply to add years to life, but to add life to those years.
