Global health
Global health means improving health and fairness in health for people everywhere. Many health threats cross borders: infections (flu, COVID-19, malaria), pollution, unsafe food and medicines, and the effects of climate change.
Big gaps exist: some places have clean water, vaccines, hospitals and many nurses; others have few. The WHO (World Health Organization), the UN and many charities work with governments. The UN's Sustainable Development Goal 3 aims at good health for all. Nurses are the largest group of health workers in the world, so their work is central.
Globalisation of targets (the people we care for)
Because of travel and work, patients come from many countries: migrant workers, tourists, refugees, foreign students and families with mixed cultures. They may speak another language, eat different food, follow another faith and have different ideas about illness.
This needs culturally sensitive care (also called transcultural nursing): ask, do not assume; use a trained interpreter; respect food, dress, prayer and privacy needs; explain in plain words; protect their rights, including if they have no insurance.
International nursing activities
International nursing work includes:
- Disaster and emergency relief with groups such as the Red Cross and Red Crescent or medical NGOs.
- Public health programmes: vaccination, maternal and child care, clean water teaching.
- Teaching and training local nurses so the care stays after visitors leave.
- Research and policy that share good practice between countries.
- Working abroad: nurses may move to another country, which needs a licence, language skill and learning local rules.
Good practice: work with local people, follow local leaders, share skills, do no harm and avoid taking away local nurses from places that need them most.
Skills of an international nurse
Four skills: communication (interpreters, pictures, patience), cultural respect (curiosity, not judgement), ethics (fairness, consent, dignity for every person) and teamwork across professions and countries. Also needed: knowledge of infection control and tropical diseases, flexibility, and care for your own health and safety.
Key formulas and definitions
- Global health = better health and fairness for people everywhere
- Culturally sensitive care: ask, interpret, respect, explain
- Four gap markers: water, vaccines, nurses, distance to care
- International work: relief, public health, teaching, research
Worked examples
1. A tourist with a stomach infection speaks no local language. What should the nurse do?
Use a trained interpreter or a phone interpreting service, use simple words and pictures, check understanding by asking him to repeat, follow infection control and protect his privacy.
2. Why does a disease outbreak in one place matter to nurses far away?
Travellers can carry the germ quickly. Nurses everywhere must watch for signs, report cases, teach prevention and vaccinate to stop it spreading.
3. A relief team trains local nurses instead of doing all the work. Why is this good?
Local nurses stay after the team leaves, so the skills last. It also respects local people and builds a stronger health system.
Common mistakes
- Thinking global health is only about far-off countries. Germs and gaps affect every place.
- Using a child or relative as translator for private health matters.
- Assuming one culture or religion has one fixed set of beliefs.
- Helping abroad without local leadership, which can harm the community.
