LONDON - When David Evans needed a hernia operation, the 69-year-old farmer became so alarmed by the long wait that he used an ultrasound machine for pregnant sheep on himself, to make sure he wasn't getting worse.
It was only after he, his doctor, and his local member of Parliament made repeated calls that the hospital performed the surgery, nearly a year after it was requested. Under government guidelines, he should have started treatment within 18 weeks.
"I was in quite a lot of pain," Evans said of his ordeal in Cornwall, southwest England. "It really restricted what I could do around the farm since I couldn't lift anything heavy."
Across Britain, an increasing number of patients are facing more pain and longer waits. That's because the National Health Service is being forced to trim $31 billion from its budget by 2015, as part of the most radical changes made since the system was founded more than 60 years ago.
For many hospitals, that means saving money by raising the threshold for who qualifies for treatment and extending waiting times for non-lifesaving surgeries.
In January, the government introduced a health bill that many fear will bring even more draconian cuts and competition from private providers. The bill, now in the process of being adopted, will ax more than 20,000 health jobs in the next two years and shut an undisclosed number of hospitals, possibly including the iconic St. Mary's in London, where Alexander Fleming discovered penicillin.
The medical profession is outraged.
"The government is wrong to ask us to cut 20 billion pounds because the pressure on the entire service is rising and with the expense of new drugs and treatments, it's impossible," said Sir Richard Thompson, president of the Royal College of Physicians.
"We've seen waiting lists go up, signs [hospitals and doctors] are trying to prevent patients from going to hospital," he said. "I think it's immoral."
Doctors and nurses have revolted. All of the top medical organizations are opposed to the health bill and many argue that scrapping the proposed changes would actually save $2.2 billion by getting rid of the bureaucratic effort to overhaul the system. The British Medical Association warned that more competition means providers could choose only to offer profitable services rather than what patients need.
Prime Minister David Cameron even had to halt the bill's progress in April to conduct a six-week "listening exercise" to get input from hostile health professionals. But while the bill still has several hurdles to clear, the government plans to put the first major changes into effect in April.
"The [health service] must be more efficient to meet the pressures of an aging population and the rising costs of drugs and treatments," Health Secretary Andrew Lansley said in a statement. "We are absolutely clear this does not mean cutting services - this means getting better value for every pound spent."
Britain's NHS is one of the country's most cherished institutions and, while grumbling about perceived slow service is widespread, its egalitarian ethos is also frequently cited as a source of national pride.
When the NHS was criticized by U.S. Republicans in 2009, a Twitter campaign in its defense became so popular it crashed the health service's site. Many leading figures, including actress Helen Mirren, former Beatle Paul McCartney, and Cameron himself proudly use government hospitals.
Only about 11 percent of Britons pay for private health care, and experts suspect that figure will remain largely static given the continuing economic crisis.
In Britain, everyone is entitled to free emergency treatment, including foreigners. Registering with a local doctor requires only proof of identification and residency; no insurance cards, paperwork or bills are needed.
In England, patients are charged a $12 prescription fee that covers whatever medicines doctors prescribe, including those for blood pressure, cholesterol, and birth control.
Such fees are waived for more than 50 percent of people who need prescriptions, as exemptions cover children, students, pregnant women, the elderly, and patients with disabilities or chronic conditions such as diabetes or epilepsy.
