Should doctors be increasing their carbon footprint by flying to medical conferences?

Flying across continents in great numbers to exchange information will soon become as outdated and unsuitable to the modern world as the fax machine and the horse-drawn carriage, writes Professor Malcolm Green, from Imperial College, London.

Driving less and low energy light bulbs can contribute a little to reducing our carbon footprint, but if doctors stop going to international conferences they could make a real difference and be seen to be taking the lead, he argues.

In 2006, over 15 000 doctors and scientists from all over the world attended the American Thoracic Society meeting in the US. The flying delegates produced about 10 800 tonnes of carbon, representing 100 million person air miles. If you add in all the conferences all over the world this would equate to about 600 000 tonnes of carbon a year, says Green, and this is without including the energy costs of large hotels and enormous conference centres.

With the advent of teleconferencing, videoconferencing and other modern technologies there is no reason why doctors cannot attend virtual medical conferences, an already highly successful and common practice in organisations such as oil companies and financial institutions, he concludes.

But Professor James Owen Drife, from Leeds General Infirmary, argues that giving up medical conferences will have only a minuscule effect on global warming.

He points out that although people respect doctor's opinions on medical matters, this influence is unlikely to extend to persuading holidaymakers, who make up 60% of UK international travellers, to stop attending football matches or tropical weddings.

He argues that conferences are essential for inspiring and motivating and can even stimulate global action—would the 1964 Declaration of Helsinki have had as much effect on research ethics if it had been a group email, he asks.

In the 1980s the internet was heralded as the replacement to such meetings, in the 1990s it was electronic conferences, and last year, "Facebook for science" appeared, but nothing, he says, can or has replaced genuine communication.

Although Drife believes doctors should continue to attend medical conferences he accepts a compromise is essential. For instance, delegates should be urged to visit and learn from local populations and there should be a networking facility to prevent conferences on the same topic being offered back to back in different continents.

But, he concludes, "hiding behind our computer screens and pretending that this is helping the planet" is not a realistic option.

Doctors bone up on orthopaedics through wiki project
Web-based academic discussions could well be the way forward for cost-effective and tailored continuing education for health professionals. China's interactive Orthochina.org wiki project for orthopaedic surgeons is an example of the potential of such internet training for continuing medical education. Zhen-Sheng Ma of the Fourth Military Medical University in Xi'an, China, and his colleagues thoroughly evaluated this online tool and will publish their results in the October issue of Springer's journal Clinical Orthopaedics and Related Research.
Doctors must step up to the challenge of climate change
Doctors must lead by example on climate change, according to experts in this week's BMJ. Health professionals were powerful catalysts in changing society's view of smoking from a normal lifestyle choice to that of a harmful addiction, and they must do the same for climate change, writes Professor Mike Gill from the University of Surrey.

Study finds amount of work for residents -- not just hours -- need review
The number of patients assigned to medical residents and the complexity of care patients require has just as much impact on residents' training as the number of hours they work, according to a study published by researchers at the University of Chicago Medical Center in the September 10 issue of JAMA.
Solid tumor cells not killed by radiation and chemotherapy become stronger
Because of the way solid tumors adapt the body's machinery to bring themselves more oxygen, chemotherapy and radiation may actually make these tumors stronger.
Researchers build new model of bio-exploration
Two land-grant universities have developed a new approach to global bio-exploration, one that returns most of the fruits of discovery to the countries that provide the raw materials on which the research depends.
Far flung food: Europe's distant diets
Across the European Union, food is travelling more, and not always in ways that make sense. Consider the chocolate covered waffle: Last year, Britain both imported 14,000 tonnes, and exported 15,000 tonnes. And it is not just waffles that are travelling further, as Europeans are eating – and importing – more food from outside the EU than ever before.
1 in 7 Americans over age 70 has dementia
One in seven Americans over the age of 70 suffers from dementia, according to the first known nationally representative, population-based study to include men and women from all regions of the country.
