The “roulette wheel”: a new tool to help patients make difficult treatment decisions

13.06.2006
Researchers at the University of California have developed an innovative new visual tool to help patients decide among different treatment options.

The new tool, described in PLoS Medicine, presents the risks and benefits of these different options in the form of a roulette wheel. The patient spins the wheel, and can then directly visualize the chances of a particular treatment leading to benefit or harm.

The researchers, led by Jerome Hoffman, show how the roulette wheel could help a healthy 65-year old man decide whether or not to be screened for prostate cancer (the screening test is a blood test called the PSA).

By spinning the roulette wheel, the man sees that if he decides to get a PSA test, he may slightly lower his risk of dying from prostate cancer but he also greatly increases the chances of becoming incontinent and/or impotent from prostate cancer treatment. The roulette wheel shows him that his chances of developing symptoms of prostate cancer are very small, whether or not he gets screened.

“Shared decision making has largely been adopted as an ideal way for physicians and patients to join together whenever there are decisions that need to be made about management of health care issues,” say the researchers.

But one of the problems with shared decision making, they say, is that physicians have traditionally presented the risks and benefits of different treatments in the form of numbers, which many people have trouble understanding. “It is hard for anyone to comprehend the difference between a 7% chance and an 8% chance,” they say, “and this is exacerbated when we try to deal in more extreme probabilities, such as 3 in 10,000.”

The researchers believe that the roulette wheel could be an important advance in shared decision making because patients are offered visual—rather than numerical—displays of the probability of benefits and harms.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
