There's something really empowering about the placebo effect. It means that you have the power to heal yourself - that's really quite remarkable. If you're not yet convinced, here are 10 breathtaking statistics about the placebo effect.
Using placebo for IBS
Irritable bowel syndrome (IBS) affects 10-15% of people around the world. It is a chronic gastrointestinal disorder with symptoms including abdominal pain, discomfort, diarrhoea and constipation. Most medications are used to treat these symptoms independently of each other and few treatments relieve the symptoms of IBS as a whole (Drossman et al. 2010). Studies have demonstrated that there is a substantial, clinically significant placebo effect for IBS. This then led Harvard researchers to investigate if using placebo for IBS could be both ethical and effective.
A doctor’s guide to placebos
Placebos are widely used in medical practice, although the exact numbers are not known. Surveys have shown that somewhere between 57-97% of doctors admit to using placebos in their clinical practice. Placebos would not be used so prevalently if they did not have positive effects, but it's vitally important that placebos are used as ethically as possible to avoid harming the doctor-patient relationship. Here, we outline different types of placebo usage, the ethical considerations and the current medical guidelines for placebos in clinical practice.
The Honest Placebo
There is something very empowering about the placebo effect and the idea that we can heal ourselves. For decades, we've known about the placebo effect, but we've been unable to use it ethically in healthcare. One of the primary obstacles to using placebos in healthcare, was informed consent. It was thought that placebos necessarily required deception - the patient had to believe it would work. However, renowned placebo researcher - Ted Kaptchuk - realised that no one had ever put that theory to the test. So he began a research programme into identifying if people could respond to placebos even if they knew they were taking placebos. The results have changed how we think about placebos in healthcare.
Luana Colloca and “The Endogenous Pharmacy”
Did you know that placebo effects and nocebo effect can be evoked without a placebo; or how about the unspoken ethics code when it comes to prescribing placebos? In a talk by Dr Luana Colloca we learn about the conflicts, ethics and future use of the placebo effect in clinical practice. Here, we summarise some of the key ideas in Dr Colloca's talk.
A Room with a View – The placebo effect and architecture
In 1983, a groundbreaking study was published demonstrating that architectural environment influences recovery from surgery. Benedetti described the placebo as "the whole ritual of the therapeutic act", so why shouldn't that also include the clinical environment? In this article, we explore the 1983 study and the implications of this in global health.
The secret prescription – Do doctors use placebos?
In 2013, a survey of UK primary care physicians revealed that 97% of them had used placebos in their career, with 77% of them using placebos at least once a week! We take a look at this and what it means for both patients and doctors.
The Curious Case of Mr Wright
Mr Wright is a case dating back to 1957, in which a patient supposedly made a miraculous recovery via placebo, before relapsing straight-away upon discovering his treatment was a sham. Placebo researchers everywhere wish this case were true, but current research into the placebo effect throws the shadow of doubt on to this incredible story.
The placebo effect and cancer – Why not?
The placebo effect works for almost any condition, except for cancer. Don't get me wrong, placebos can help combat the symptoms of cancer, but they are useless when it comes to fighting the cancer itself. But why is this?
“Great architecture can heal”
In 2016, Michael Murphy did one of my all time favourite TED Talks. It's entitled 'Architecture that's built to heal' and he discusses architecture as a means for physical, emotional and societal healing. His inspiring talk made me feel that this is something we should make more of. https://www.youtube.com/watch?v=MvXZzKZ3JYQ Getting inspired Michael Murphy was inspired to action … Continue reading “Great architecture can heal”
