It might seem ironic that the one health outcome that will eventually happen to every one of us — dying — is very difficult to predict, even for patients with life-limiting illnesses. But information is often the key to good health-care decisions, and that includes decisions about end-of-life care. Even though it’s difficult to talk about, getting an accurate idea of how long an ill person will survive can enable the best planning for palliative care and ensure their individual preferences are met.

Today in The Conversation Canada, Lysanne Lessard, Amy Hsu and Peter Tanuseputro of the University of Ottawa and Sampath Bemgal of the University of New Brunswick write about using data and algorithms to predict life expectancy with the Risk Evaluation for Support: Predictions for Elder life in their Communities Tool (RESPECT). The tool asks 17 questions and bases predictions on the experiences of others in similar circumstances.

“The tool can help patients understand their own illness trajectory, have earlier conversations about their preferences and wishes, and advocate for the support they need,” they write.

How long will a loved one live? It’s difficult to hear, but harder not to know

An accurate prediction of survival can enable earlier conversations about preferences and wishes at the end of life, and earlier introduction of palliative care.

Our grocery stores are increasingly filled with ultra-processed foods, which have little to no nutritional value and a huge environmental impact. (Nathalia Rosa)

Ultra-processed foods are not only bad for our bodies, their production damages our environments

Ultra-processed foods are bad for our health and our planet and must be central to any efforts to reduce our carbon emissions, and waistlines.

While the digital landscape offers opportunities for unions to engage and mobilize supporters, it also presents challenges, including the risk of being marginalized in the vast online world.

Why Einstein must be wrong: In search of the theory of gravity

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
