Media reports may see patients stop statins… again

A new UK study has supported Australian evidence that the media can influence whether people stop taking their medicines: and again, the medicines involved are statins.

A period of controversy over the risks and benefits of statins was covered widely in the UK media and followed by a temporary increase in the number of people stopping their statin treatment, a study in The BMJ has found.

The increase in stopping was seen among patients taking statins for existing heart disease as well as patients at high risk of developing disease in the next 10 years.

The researchers found no evidence that widespread media coverage was linked to changes in the proportion of newly eligible patients starting statins.

The results are observational, so no firm conclusions can be drawn about cause and effect, but the authors say they highlight “the potential for widely covered health stories in the lay media to impact on healthcare related behaviour.”

A linked editorial argues that uncertainty over the benefits and harms of statins still exists and journalism that exposes the public to ongoing controversies in science should be nurtured.

In October 2013, two articles were published in The BMJ that questioned the value of extending the use of statins to healthy people at low risk of heart disease, and these were heavily criticised by some statins researchers, prompting widespread media debate about their potential risks and benefits.

Anthony Matthews at the London School of Hygiene and Tropical Medicine and colleagues decided to measure how the period of intense public debate from October 2013 to March 2014 affected the likelihood of patients starting and stopping statins for both primary and secondary prevention of CVD.

Using prescribing data from UK primary care records, they calculated the number of people aged 40 and over starting and stopping statins each month from January 2011 to March 2015.

Patients already taking statins were more likely to stop taking them for both primary and secondary prevention after the high media coverage period, particularly older patients and those with a longer continuous prescription.

The authors estimate that more than 200,000 patients across the UK may have stopped statin therapy in the six months after the media coverage – and that this could lead to over 2,000 extra cardiovascular events, such as heart attacks and strokes, if continued over the next 10 years.

But they stress that these calculations are based on several assumptions and should be interpreted with caution.

Study author Professor Liam Smeeth from the London School of Hygiene and Tropical Medicine says: “Our findings suggest that widespread coverage of health stories in the mainstream media can have an important, real world impact on the behaviour of patients and doctors. This may have significant consequences for people’s health.

“It’s undoubtedly important that these debates are reflected in the media, who play a key role in communicating public health advice, but there is a concern that in the case of statins, widespread reporting of the debate may have given disproportionate weight to a minority view about possible side effects, denting public confidence in a drug which most scientists and health professionals believe to be a safe and effective option against heart disease for the vast majority of patients.”

In a linked editorial Gary Schwitzer, Publisher of, says “we should not rush to judgement on the media’s role in this episode.”

He asks: what if news coverage did have an effect, by alerting people to the debate and uncertainty that still exist about the extent of potential benefits and harms of statin use, and is that such a bad thing?

He points out that the authors provide no patient data to support the belief that people stopped because of news reports, nor did they explore the possibility of reduced side effects, such as muscle pain and diabetes, as a result of stopping.

“If news stories generate new questions from patients, or more complete conversations between patients and clinicians including better discussions on trade-offs, personal preferences, and values, that is an outcome to embrace,” he says.

A second paper, also published today, estimates discontinuation rates of statins for over half a million UK patients and finds that, although more than 40% of statin users discontinue their therapy at some point, more than 70% of these restart.

Because of the lack of data on reasons for discontinuations, however, the study cannot directly address why some patients discontinue statins.

In Australia a study examining how the ABC’s Catalyst program, Heart of the Matter, influenced statin discontinuation was recently awarded the 2015 MJA, MDA National Prize for Excellence in Medical Research.

The study, The crux of the matter: did the ABC’s Catalyst program change statin use in Australia? showed that there was a temporary increase in discontinuation and a sustained decrease in overall statin dispensing following the Catalyst piece.
