To be more precise, the evaluation tool, officially named “Criteria for Screening and Triaging to Appropriate Alternative Care (CrisTAL), is a screening checklist designed to help doctors identify elderly frail people at risk of death within 90 days.
The death test was developed by researchers at Sydney, Australia’s Simpson Centre for Health Services Research at the University of New South Wales. The CrisTAL evaluation checklist was compiled as a result of research lead by Dr. Magnolia Cardona-Morrell. The study findings were published in the journal BMJ Supportive & Palliatative Care. According to Cardona-Morrell, CriSTAL was devised to improve doctors confidence in the prognosis so they can tell patients the truth about their prognosis.
While referred to as a death test in the popular press (and in this article), Dr. Cardona-Morrell believes it would be much more accurate to refer to the tool as the “end-of-life checklist” or the “end-of-life decision-making tool.”
A test to identify those elderly patients most at risk of dying within 90 days has been developed by doctors.
They say the test will give people the chance to go home and spend time saying goodbye to loved ones, preventing them from enduring their last days in hospital.
The 29-point checklist will prevent futile and costly treatments that prolong the patient’s suffering and frustrate doctors, the researchers said.
The test comprises a checklist of 29 predictors of health including age, frailty, the severity of their illness and mental impairment.

To come up with the death test, Dr. Cardona-Morrell and her team studied relevant articles and scholarly papers. These papers addressed issues such as the definition of dying, preferred place of death, and liklihood of options for end-of-life care. Based on their research the team came up with the death test criteria. Based on these criteria doctors should be able to assess the probability that a patient will recover and use this as the basis for a discussion of the patient’s options. The end-of-life checklist is still under refinement and further research is needed to test the test and caregivers will require training in its application.
