Concerns have been raised about the use of the internet and new technologies to revolutionise health care.

The internet is revolutionising health care

There has been a rise in the use of online drug sales and private DNA¹ tests and scans in recent years, says the Nuffield Council on Bioethics.

But the independent group said such changes may be putting patients at risk or leading to unnecessary alarm.

Nuffield officials said more regulation may be needed and have launched a consultation² to discuss the issues.

The group said it wanted to hear about patients' experiences and the views of private companies offering these services.

The council said there was a whole host of questions that needed to be addressed about a range of services.

For example, it said the information provided by DNA profiling or body imaging using MRI and CT scans could be misleading and difficult to interpret.

Professor Christopher Hood³, an Oxford⁴ University expert who is heading the consultation, said this could sometimes have a knock-on effect（撞击效应） on the NHS with people coming to it with unnecessary medical worries.

The consultation paper also raised concerns about the selling of drugs on the internet.

Last week a poll of GPs found that one in four had treated patients for adverse⁵ reaction（有害反应，逆反应） to medicines bought online.

Professor Hood said: "Cutting out the GP may sometimes be a good thing, providing us with convenience, privacy and control over our health.

"But there is not much regulation of these new services and we may be getting information that causes more harm than good."

Benefits

But the consultation also said the advance in technology could offer opportunities to the NHS.

One of the examples given was the use of telemedicine in rural areas to allow GPs and patients to use TV link-ups for consultations⁶.

Nuffield director Hugh Whittal said: "There is a range of benefits to be had, but it is only right some questions are asked about risks, the quality of information, equity⁷ of access and the impact on the NHS."

Professor Steve Field, president of the Royal College of GPs, said: "I think this just reinforces the need for patients to have a GP.

"Doctors should be empowering patients and help them understand and navigate⁸ their way through what is being offered."

But he also warned patients to be wary⁹（当心） of some of the services being offered by private firms.
