Needless Screening Tests for Cancer Patients

Subjects:

The US health care system is generally recognized to be obscenely wasteful and to deliver poor value for the money. But even the most jaded observers are likely to be shocked by the results of a new study which shows that many patients with advanced or metastatic cancer and a correspondingly short life expectancy undergo routine screening tests like cholesterol checks, Pap smears, mammograms and PSA tests.

For example, 14% of male Medicare beneficiaries with advanced pancreatic cancer underwent PSA testing. Similarly, 18% of women with this condition had at least one mammogram and 5.4% had a Pap smear. Nearly 20% of these patients had a cholesterol test.

The appalling findings come from a study by Camelia Sima and colleagues at the Memorial Sloan-Kettering Cancer Center. These scientists looked at Medicare billing data from 88,000 beneficiaries that had been diagnosed with advanced cancer between 1998 and 2005.

The scientists compared utilization rates for screening tests in this group with a control group of Medicare enrollees that did not have cancer, but were matched by gender, age, race and area of residence.

The first group included patients with stage IIIb to IV lung cancer, advanced stage pancreatic cancer and stage IV breast,colorectal, and gastroesophageal cancer. The vast majority of these patients have a life expectancy of less than 2 years.

Screening rates for the cancer patients were about half that of their matched controls. There were no differences in screening rates for patients with each kind of cancer. Married and more affluent cancer patients tended to get more screening tests than their counterparts.

“In an ideal healthcare system, healthcare practitioners would discontinue cancer screening for patients whose prognosis is too limited for the benefits of early detection to be realized,” Sima’s team wrote. “Each medical specialty needs to engage in thoughtful self-scrutiny to identify episodes of unnecessary care,” they added.

The write-up appears in JAMA.
