When people compare healthcare systems, they usually compare waiting lists, staffing levels, or funding. After spending more than two decades in the NHS, and the last two years working in the HSE, I have become fascinated by something altogether quieter – language. Sometimes an institution reveals its character not in policy documents or organisational charts, but in the ordinary words it chooses.
One example has stayed with me. The NHS speaks of ‘bare below the elbows’. The HSE asks staff to remain ‘bare above the wrists’. At first glance, they describe the same thing. Microbiologically, they largely do. Both seek effective hand hygiene, unobstructed wrists and forearms, and the removal of clothing and jewellery that interfere with patient safety. Yet I have often wondered why two neighbouring healthcare systems chose different words. Perhaps because they reveal something deeper than anatomy. Perhaps they reveal culture.
More than sleeves
When I began medical school in India, nobody wore a tie. The prized possessions of a young doctor were the long white coat and, if one could afford it, a good stethoscope. They were symbols of belonging. When I arrived in Britain to continue my training, I discovered another expectation; doctors wore ties. I learnt to knot one properly and bought several because that was simply what doctors did. Then, almost without anyone noticing, the culture changed. The white coats disappeared. The ties disappeared. Long sleeves disappeared. ‘Bare below the elbows’ became part of everyday professional life. Looking back, I think those practical infection prevention measures quietly redefined what professionalism looked like.
A revolution without speeches
The NHS never announced a cultural revolution, it simply changed everyday habits. Alcohol hand rub appeared outside every patient room; watches disappeared, bracelets disappeared. The tie quietly became unnecessary. Authority no longer resided in appearance. It increasingly resided in behaviour. Today, patients may not notice whether a doctor wears a tie. They are far more likely to notice whether the doctor cleans their hands.
The quiet leaders
During my time in Ireland, one observation has remained constant. The infection prevention and control nurses I have worked alongside have been remarkably diligent. They know the guidance thoroughly. They apply it consistently. They follow it faithfully, often in circumstances that are far from ideal. Yet guidelines are only one part of infection prevention. Culture is the other.
Healthcare buildings evolve over decades. Clinical pressures rarely ease. Resources are never unlimited. Long-established professional habits do not disappear simply because a guideline has changed. That is where infection prevention becomes something much larger than compliance. It becomes leadership.
Authority rarely comes from hierarchy. It comes from evidence, credibility, consistency, and the quiet confidence that patient safety must remain the same regardless of who happens to be standing beside the bed. Healthcare remains a profession where seniority matters, where consultants, quite rightly, carry ultimate responsibility for patient care, and where established ways of working can be deeply embedded.
Changing culture therefore requires something more persuasive than authority. It requires trust. The quiet leaders rarely command. They persuade, they educate, they remind. Then, they return the next day and begin again. Real cultural change seldom occurs because someone wins an argument; it happens because someone patiently wins confidence.
Evidence and authority
Working in two health systems has also made me reflect on how professional authority evolves. One of the strengths I have observed in Irish hospitals is the respect afforded to consultants. Their leadership is visible, reassuring, and deeply valued. Their opinion often carries influence well beyond the immediate clinical decision.
The NHS, too, remains consultant-led. Yet over the past two decades that phrase has acquired a different flavour. Leadership increasingly feels shared. The consultant remains accountable, but decisions emerge through conversations involving nurses, pharmacists, microbiologists, therapists, advanced nurse practitioners, and junior doctors. Perhaps infection prevention has contributed quietly to that evolution. Microorganisms, after all, pay little attention to professional hierarchy. Evidence gradually acquires an authority of its own.
The courage to stop
Increasingly, my advice as a microbiologist is to recommend stopping antibiotics. The question is no longer simply: ‘What antibiotic should we prescribe?’ It has become: ‘Does this patient still need one?’ Many younger doctors understand this instinctively, yet they often find themselves navigating between newer evidence and older habits. Evidence usually moves first, practice follows. Culture is often the last to arrive.
Lessons from two phrases
‘Bare above the wrists’, ‘bare below the elbows’ – one defines the practical minimum required for effective hand hygiene, the other has come to symbolise an entire professional philosophy. Neither phrase is really about sleeves. Both are about culture.
A drawer full of history
I still have the ties I bought when I first arrived in Britain. They have not been worn for more than 20 years. I have never added another. They remain carefully folded in a drawer, neither useful nor discarded. Looking at them now, I no longer see items of clothing. I see reminders that professions evolve quietly; not through dramatic declarations, not through sweeping reforms, but through thousands of ordinary decisions repeated every day by nurses, doctors, healthcare assistants, pharmacists, therapists, cleaners, and patients who gradually agree that there is a better way.
By the time we notice the change, the culture has already moved on. Policies can be written overnight, evidence can be published in a journal, but culture changes only when people patiently help one another to see the world differently. That is the quiet revolution.
