Tool can accurately predict risk of death within one year of hospital admission

June 17, 2015


Has someone you love recently been admitted to the hospital? Would you like to know what their chance of dying is within the next year? If so, this can now be easily calculated using the HOMR (Hospital-patient One-year Mortality Risk) model developed by Dr. Carl van Walraven and colleagues. They recently published a study in the Canadian Medical Association Journal (CMAJ) validating the HOMR tool in more than 3 million patients in Ontario, Alberta and Boston. “An accurate assessment of risk of death, particularly if that risk is high, could motivate and inform discussions between patients and physicians regarding goals of care,” said Dr. van Walraven. The model could also help hospitals measure and compare performance. Dr. van Walraven was interviewed about this research in the Ottawa Sun.
