A simple points system may soon help guide treatment of elderly heart failure patients. Researchers at Washington University School of Medicine in St. Louis found that by counting how many of seven easy-to-obtain health factors a patient has, physicians can estimate the patient’s risk of dying.
“The system is easy to use, and the variables don’t require any specialized testing — they are part of routine medical histories or basic lab tests,” Rich says. “If the system can be validated by further studies, it can play a role in helping physicians tailor care to individual patients. If a person has a limited life expectancy, it may not be in his or her best interest to recommend invasive, uncomfortable or risky procedures. On the other hand, an elderly person with only one risk factor could potentially be considered a good candidate for an aggressive treatment such as a defibrillator.”
Other factors that might have been expected to affect survival, such as the amount of blood the heart can eject during pumping or a patient’s body mass index, didn’t seem to influence survival times. Rich emphasizes that each of the factors identified has been linked in previous studies to poor prognosis in heart failure patients.
“We didn’t find any new risk factors, which means there’s good data to support that these factors truly are predictive,” Rich says. “We’ve pinpointed the seven that are the most predictive and shown that the number of risk factors can give a reasonable estimate of the probability of living for six, 12 or 60 months.”
The researchers next aim to better identify the heart failure patients not likely to survive six months so that they can be referred for hospice care.
“Hospice is very nurturing for both patients and family members,” Rich says. “There is considerable evidence that patients derive significant benefit from it. If we can predict mortality within six months, we can more easily establish eligibility for hospice care.”
