TUESDAY, March 5 (HealthDay News) -- A simple checklist could help doctors estimate whether an older patient will be alive 10 years from now, according to a new study.
Researchers hope the findings, reported in the March 6 Journal of the American Medical Association, will help older adults and their doctors come to better decisions on health care.
There currently are national guidelines on medical procedures like colon cancer screening and mammography screening for breast cancer -- but they give general guidance, not individual.
The checklist could help better tailor advice to older patients, said lead researcher Dr. Marisa Cruz.
"It's meant to be used in a clinical context, to help doctors and older patients discuss screening and other interventions," said Cruz, a clinical fellow at the School of Medicine at the University of California, San Francisco.
Guidelines on cancer screening tests and other interventions vary, but they are based on averages. And some guidelines suggest age cutoffs for screening, because there's a lack of evidence that the tests benefit the average person past a certain age.
Colon cancer screening is one example. The U.S. Preventive Services Task Force, an independent panel that advises the federal government, says that for most people, colon cancer screening should begin at age 50 and continue only until age 75. Other groups, including the American Cancer Society, do not give an upper age limit, but say doctors should consider an older patient's overall health and life expectancy. For an elderly person in poor health, an aggressive treatment or even a screening test could do more harm than good.
On the other hand, a 75-year-old in good health could live many more years, and may benefit from cancer screenings or aggressive treatments, such as tight blood sugar control in people with diabetes.
