The figures were produced by the doctors' union the BMA, which has had long-standing concerns over NHS 111.
Doctors' leaders say increased referrals mean more pressure on already overstretched GPs and hospitals.
NHS England says the 111 service is meeting increasing demand.
A spokesman said the proportion of referrals to GPs and emergency services had remained steady despite a surge in calls.
But the BMA is concerned that the service is not delivering appropriate advice to some patients and this means some are being incorrectly directed to busy hospitals and GP surgeries.
The BMA looked at the outcomes of calls to NHS 111, which was rolled out in March 2013 to replace the old NHS Direct service.
In its final full year of operation in 2011-12, NHS Direct received 4.4 million calls from patients.
In comparison, calls to NHS 111 increased year-on-year and in 2014 (up to November) it received and responded to more than 15.4 million calls.
Referrals from NHS 111 to A&E increased from just under 400,000 calls in 2013 to over a million in 2014.
Similarly, referrals to GPs went up from just under 3 million to 8 million between 2013 and 2014.
Dr Charlotte Jones, BMA's GP lead on NHS 111, is concerned that the service is not delivering appropriate advice for patients.
"There is no doubt that if a patient needs any form of medical care they should be referred through to an appropriate doctor or nurse, but there are serious doubts as to whether this huge increase in workload is clinically necessary.
"Anecdotally, GPs have reported to the BMA that patients have been referred to them with colds, sore thumbs or other conditions that could have been treated safely by sensible advice over the phone, advising a patient on how to self-care, such as picking up medication from a local pharmacist."
And Dr Mark Porter, of the BMA, says there is an issue with staff who have little or no medical knowledge.
"A fundamental problem with NHS 111 is that it employs non-clinically trained staff who follow a formulaic script rather than using clinical judgement to assess how calls are dealt with.
"Understandably this is likely to lead the call handlers, with limited experience of medicine, to be cautious and refer patients to the NHS when a trained professional could have encouraged them to effectively self-care.
"Key NHS services cannot afford to be taking on unnecessary work when they are struggling to treat the number of patients who do need genuine care.
"It is also an enormous waste of patients' time if they are sent to a GP or A&E when they could have had their issue dealt with during a few minutes on the phone."
An NHS England spokesman said the statistics show there is a massive demand from the public for the 111 service.
"To date, it has coped impressively with this pressure, with the proportion of referrals to GPs and emergency services remaining steady despite the surge in demand.
"Given this popularity, however, we are continuing to look at ways to make the service even more robust including asking GPs to help support call centres and provide patients with the ability to get high quality medical advice as quickly as possible."
Janette Turner, a research fellow for the emergency and immediate care group at the University of Sheffield, said: "We must remember NHS 111 is not the same as NHS Direct and of course call volumes are much higher because 111 has not only replaced NHS Direct, but also GP out of hours services.
"Today's BMA statements are anecdotal and what isn't known is if there was no 111, how many of those people would have actually gone in to their GP, A&E or Walk-In Centres."
There has been a big increase in the number of people being referred to GP surgeries and A&E departments, analysis of the NHS 111 urgent care line in England shows.

Adrian Bayford, 41, and his 40-year-old wife Gillian, of Haverhill, Suffolk, won the UK's second biggest ever lottery prize in Friday's lottery draw.
Speaking at a media briefing, Mrs Bayford said they would share the money with people who had supported them.
They have a six-year-old daughter Aimee and a son, Cameron, aged four.
Mr Bayford, who co-owns Suffolk Music Centre in Haverhill, said he convinced his wife that they had both forgotten to buy a ticket when they watched Friday's draw.
He then went and checked the ticket he had bought, with Mrs Bayford describing him as "going a bit pale".
She said: "I checked the numbers on my phone, the TV, the internet - and we just looked at each other and giggled."
Mrs Bayford, a health care assistant at the children's ward at Addenbrooke's Hospital in Cambridge, said they did not sleep that night.
The couple, who have been married for eight years, spent the night on the internet deciding how to spend the huge jackpot, the result of 14 rollovers.
Mrs Bayford said she planned to quit her job but her husband, originally from Hayle in Cornwall, said he wanted to return to the business he started as a market stall.
"I find it hard to take in the actual quantity of it," added Mrs Bayford.

It was the moment the identity of Britain's newest multi-millionaires was revealed.
As Adrian and Gillian Bayford stepped into the media briefing, they were met with a flurry of flash bulbs and television cameras.
The assembled ranks of around 50 journalists were waiting at the luxury hotel in Hertfordshire, keen to learn what they intended to spend their vast fortune on.
After spending time smiling, kissing and turning on cue for television cameras and newspaper photographers, it was time for the questions.
Sitting side by side, they seemed happy to speak about what their lives had been like and how it might change now.
Despite their newly-found riches, Gillian confessed it might be hard to kick old habits, revealing that she had already bought another lottery ticket.
"We have always worked and saved up for holidays or things that we need.
"We have lived within our means and been comfortable but we have been like ships in the night to earn the income we needed.
"It will be fantastic to spend more time as a family now.
"This money has come at the right time for us and is going to benefit the whole family."
They said the amount they won was life-changing "not just for us, for everyone", saying they would look to repay people who have helped them financially, both friends and family.
"It is such a large amount that it isn't something for one person," Mrs Bayford added.
"It is something to share with other people, people that need help, people that have helped us and supported us."
She added: "I'm Scottish, we're known for being tight, I'll still be hitting the sales.
"This month had been an extremely tight month, to be honest.
"We had gone shopping the other day and I had spent some money on the children for some holiday clothes.
"I actually got home that night and thought 'hmmm, I really shouldn't have spent that' because I'm a bit short this month, my night shifts hadn't been as many as I previously had."
The couple plan to start the search for their dream home, with Mrs Bayford keen to buy the car of her dreams, an Audi Q7.
Her husband said he had always wanted to visit the Canadian Rockies by train, and the children want to go to Disney World.
Mrs Bayford, who is originally from Kirkcaldy in Fife, added: "Children's charities are close to our hearts so we will be exploring how we can use this money to help those charities but it is too soon to say exactly what."
According to The Sunday Times Rich List, they now have a fortune to rival Jamie and Jools Oliver (£150m), Sir Tom Jones (£140m) and Eric Clapton (£130m).
Their win places them 516th in Britain's Rich List.
A couple who won £148m on the Euromillions lottery have said it was life-changing "not just for us, for everyone".

English Heritage (EH) is bringing in a Â£15 charge per vehicle to encourage people to car-share or use the bus.
But, villagers in nearby Shrewton are worried revellers will park "all over the place" to avoid the Â£15 levy.
EH said it had "robust" plans in place for the events.
A meeting between residents and English Heritage, is due to be held later.
Shrewton is around 2 miles (3.2 km) from the ancient site. According to residents, there has always been a parking issue and if EH charges "these high prices" it will exacerbate it.
Councillor Ian West, said: "It's very much a walkable distance.  In the past they've had problems with blocking drives - so there's a real amount of concern."
Parish councillor Alan Harris, described it as a "money-making operation".
"They're expecting a number of people to walk or to get there by any other means," he said.
"So, they're pretty much saying go park in Shrewton and walk here and you can get in for free."
But Kate Davies, Stonehenge general manager, said it was "strongly encouraging" people to come by public transport or to car-share.
"We have robust car parking and traffic management plans in place - any vehicles parked illegally or causing an obstruction will be removed by the police," she said.
In 2000, approximately 10,000 people attended the solstice, while in 2014, the figure was close to 40,000.
EH also pledged to keep access to the monument free during the celebrations, despite growing attendances.

Residents in villages within a "walkable distance" of Stonehenge are concerned they will be "inflicted with masses" of cars when parking charges are introduced at this year's Solstice.
