A Check on Physicals
By JANE E. BRODY
“Go Beyond Your Father’s Annual Physical. Live Longer, Feel Better”
This sales pitch for the Princeton Longevity Center’s “comprehensive exam” promises, for $5,300, to take “your health beyond the annual physical.” But it is far from certain whether this all-day checkup, and others less inclusive, make a meaningful difference to health or merely provide reassurance to the worried well.
Among physicians, researchers and insurers, there is an ongoing debate as to whether regular checkups really reduce the chances of becoming seriously ill or dying of an illness that would have been treatable had it been detected sooner.
She cited the medical saga of Brian Mulroney, former prime minister of Canada. A CT scan performed as part of a checkup in 2005 revealed two small lumps in Mr. Mulroney’s lungs. Following surgery, he developed an inflamed pancreas, which landed him in intensive care. He spent six weeks in the hospital, then was readmitted a month later for removal of a cyst on his pancreas caused by the inflammation.
The research team, led by Dr. Lasse T. Krogsboll, analyzed the findings of 14 scientifically designed clinical trials of routine checkups that followed participants for up to 22 years. The team found no benefit to the risk of death or serious illness among seemingly healthy people who had general checkups, compared with people who did not. Their findings were published in November in BMJ (formerly The British Medical Journal).
In introducing their analysis, the Danish team noted that routine exams consist of “combinations of screening tests, few of which have been adequately studied in randomized trials.” Among possible harms from health checks, they listed “overdiagnosis, overtreatment, distress or injury from invasive follow-up tests, distress due to false positive test results, false reassurance due to false negative test results, adverse psychosocial effects due to labeling, and difficulties with getting insurance.”
Furthermore, they wrote, “general health checks are likely to be expensive and may result in lost opportunities to improve other areas of health care.”
