Cameron's NHS spending pledge is worthless

The PM claims that spending will rise but the figures show that it will be frozen or even cut.

One of David Cameron's "five guarantees" on the NHS is that spending on the health service will rise "in real terms" over the course of this Parliament. In his speech on the NHS today, the PM boasted that there would be "£11.5 billion more in cash for the NHS in 2015 than in 2010". He added: "We are not cutting the NHS. In fact, we are spending more on it."

Cameron is referring to the fact that spending on the NHS, which currently stands at £102.9 bn, will rise to £114.4bn by 2014-15, a cash increase of £11.5bn. But what he ignores is that all of this increase will be swallowed up by inflation. The purchasing power of the NHS will be progressively reduced as the price of drugs and equipment continues to rise.

Once we take inflation into account, health spending will be frozen or even cut. As Professor John Appleby, chief economist at the King's Fund, writes in the latest edition of the British Medical Journal, "by 2014-15 the amount of money the NHS has to spend in real terms, its purchasing power, will have gone down by 0.9%." Thus, not only will Cameron fail to meet his flagship pledge to increase spending on the NHS "in real terms", he will fail to even protect it from the cuts.

Of course, George Osborne could announce an inflation-busting increase in health spending to ensure the government keeps its pledge (although that would mean even larger cuts elsewhere). But for now, it's simply dishonest of Cameron to claim that he is raising spending on the NHS. Without any new money, his "spending guarantee" is worthless.

A clinically-approved birth control app is changing the way we think about contraception

The particle physicist Elina Berglund has created an app that is 99 per cent effective. 

Women around the world using the contraceptive pill have long complained to their friends about its perceived side effects – weight gain, acne, mood swings to name a few. Some more recent studies have verified that anecdotal evidence – a Danish study from 2013 confirmed that there was a 40 per cent increased risk of depression for women who were on the pill, compared to those who weren’t.

Frustration around the inadequacy or ill-suitability of certain methods of contraception is rife. One woman, Elina Berglund, decided to do something about it.

Formerly a particle physicist at CERN (and a member of the team responsible for the discovery of the Higgs Boson particle), Berglund co-founded Natural Cycles, a contraceptive app, with her husband Raoul Scherwitzl. Approved as a contraceptive app earlier this year, it is downloadable on a smartphone and relies on a relationship between body temperature and fertility to tell women when they're fertile.

But contraception campaigners have viewed the concept with caution. Widespread use of the pill, condoms, and diaphragms comes after decades of campaigns against reliance on "natural methods" – not to mention the opposition of religious organisations like the Catholic church. 

At first glance, Natural Cycles might not seem all that different from the Vatican-approved "rhythm method", which is based on observing the exact stages of a woman's fertility cycle and avoiding sex during ovulation. This can be, according to the NHS, up to 99 per cent effective – but in reality it is closer to 75 per cent, because "people can make mistakes". 

Users of Natural Cycles take their temperature daily and input it into the app (which costs £6.99 a month). The app then compares the figure to its own dataset and uses an algorithm based on Berglund's days from CERN. It also asks for other data, such as the dates of user's periods and whether they are planning for a pregnancy or not, to create a personalised calendar.

If it’s safe to have unprotected sex, then the in-app calendar will show up as green. If not, the in-app calendar will show up as red. On those red days, users should find methods of contraception if they aren’t seeking pregnancy.  

Menstrual tracking apps are all the rage (there are around 1,000 of them on the current Apple app store). But recent studies have shown that those apps are often inaccurate and lack any scientific basis. 

Natural Cycles, by contrast, carried out three clinical trials, each time expanding the dataset to reduce errors. The most recent, written up in Contraception, involved 22,785 women across 37 different countries in settings that mimicked real life. The co-authors pointed out that in instances of perfect use, one out of 100 women become pregnant accidentally. However, in instances of typical use, seven out of 100 women had the same result.

When Natural Cycles first gained publicity, Berglund pointed out to the press that “now they (women) have a new, clinically verified and regulatory approved option to choose from”. Berglund and Scherwitzl are looking into getting Natural Cycles prescribed on the NHS, like the pill.

So is Natural Cycles the future of family planning? The first thing to make clear is that the app cannot actually function as physical contraception – on “red” days, the app advises users to use a condom if they’re having sex and don’t want to get pregnant. It cannot prevent the transmission of sexually transmitted diseases either. 

Nor is the app really marketed to those who may benefit from the most information about their sexual health – 16 to 25-year-olds, who are also the age group most likely to engage in risky sexual behaviour. 

A spokesperson for Marie Stopes, the reproductive health NGO, said: "Apps to track fertility are a high-tech version of what women have been doing for years with a diary and a thermometer.

"For anyone trying to get pregnant, they might well help. However, if you want to avoid pregnancy, it’s much better to choose a reliable, long-acting modern method of contraception like an IUD or implant. Traditional methods, including tracking fertility, carry a much higher risk of unintended pregnancy."

The app relies on an algorithm, meaning it is only as effective as the data that it receives from users. It is also not free, which may exclude its usage by certain sections of society. A blog written for NHS Choices emphasised that the data collected in all the trials was collected from women who were already signed up for the product, making it likely that they had an incentive to continue with this specific additional contraceptive, as opposed to looking elsewhere. Even so, a third of users who had signed up still dropped out, potentially because of the maintenance required to get results from it. 

All the same, Natural Cycles has 380,000 users and counting. It has received clinical approval to be marketed as a medical device, and it seems to be meeting a need – 70 per cent of Natural Cycle's users come from hormonal contraception, according to Berglund. In her account of Natural Cycles in the Evening Standard, Kate Wills highlighted that the Apple Watch had all sorts of health inputs, but no way to track periods.  All kinds of apps exist to make modern life easier – why has it taken so long for one that addresses a concern for so many women to make its way into the mainstream?

The history of contraception is littered with examples of women being ignored. Early birth control studies vastly underplayed the potentially debilitating side effects of hormone fluctuations on women’s mental health and physical appearance, often treating users as though they were hysterical. Add into the equation the stigma around accessing contraceptives safely and non-judgementally, and it’s easy to see why a relatively painless and private form of contraception might be appealing. 

Natural Cycles may well work for some women – those who are in stable relationships, hoping to get pregnant and fastidious enough to note their temperature every morning. But it doesn’t prevent diseases, requires a steady commitment and – here's the clincher – can't take measurements when you’re hungover as alcohol can affect your temperature. There's also a big difference between the "perfect" use of the app, and the likelihood of pregnancy when used in a "typical" fashion. So long as that's the case, old-fashioned contraception seems unlikely to be swept away by a digital revolution.
