Boomers, Seniors Lead Rush to Weight-Loss Surgery
Associated Press
July 12, 2005 – Lead my a 900 percent increase by baby boomers and young seniors citizens between the ages of 55 and 64, Americans turning to weight-loss surgery quadrupled between 1998 and 2002 – from 13,386 to 71,733. It is estimated this number had doubled again by 2004, when there were about 141,000 that chose bariatric surgery, which is also known as gastric bypass surgery.
Approximately 395,000 Americans between 65 and 69 years of age will be medically eligible to have weight-loss surgery this year, and this number could increase by approximately 20 percent, to 475,000, in 2010, which would have important cost implications for the Medicare program, according to the study by HHS' Agency for Healthcare Research and Quality. The study is being published in the July 12 issue of Health Affairs.
During the 1998 to 2002 time period, hospital costs for treating patients who underwent weight-loss surgery increased by more than six times—from $157 million a year to $948 million a year—and the average cost per surgery increased by roughly 13 percent, from $11,705 to $13,215.
To be considered medically eligible for weight-loss surgery, known technically as bariatric surgery, a patient must have a Body Mass Index greater than 40 (or greater than 35 with serious obesity-related complications such as type 2 diabetes or obstructive sleep apnea).
The authors estimate that future demand for weight-loss surgery could rise even more sharply as safety concerns diminish.
To date, only a small fraction of people who are medically eligible for weight-loss surgery have actually had the procedure; in 2002, for example, only 0.6 percent of an estimated 11.5 million morbidly obese patients underwent weight-loss surgery. Meanwhile, in-hospital death rates among weight-loss surgery patients as a whole fell by 64 percent—from 0.89 percent to 0.32 percent between 1998 and 2002. In spite of the overall decline, the death rate for men, which dropped from 2.76 percent to 0.79 percent, was still three times higher than the 0.24 death rate for women.
"This study clearly shows another side of the challenge that America's obesity epidemic poses to the Nation's health care system. In the absence of more effective means of preventing obesity, the demand for surgery and its costs will continue to increase," said AHRQ Director Carolyn M. Clancy, M.D. "These findings provide valuable national estimates for the present and future for Medicare, Medicaid and private health plans."
The authors further suggest that future use and costs of prescription weight-loss drugs also could increase significantly. While 63 million Americans were medically eligible for weight-loss drugs in 2002, less than 2.4 percent were prescribed them. The average spending on weight-loss drugs that year was $304 per patient, with health plans paying roughly three-fourths of the expense and patients paying the balance.
According to lead study author William E. Encinosa, Ph.D., newer, more effective drugs now under development to block cravings or appetite will likely increase the demand for prescription weight-loss medications.
The authors based their estimates on data from the Nationwide Inpatient Sample, a database of the Healthcare Cost and Utilization Project sponsored by AHRQ in partnership with data organizations in 37 states. The Nationwide Inpatient Sample is the largest all-payer inpatient care database in the United States from which national estimates of inpatient care can be derived. Data are also from the Medstat 2002 MarketScan Commercial Claims and Encounter Database. The MarketScan database contains claims for inpatient hospital care, outpatient care, and prescription drugs for enrollees under age 65 in employer-sponsored benefit plans for 45 large employers across the United States.
TYPES OF WEIGHT LOSS SURGERIES
Weight loss surgery can be divided into three types:
Restrictive procedures reduce the size of your stomach.
Malabsorptive procedures alter the flow from your stomach to your intestine, causing poor absorption of calories, vitamins, and minerals in the intestine.
Combination procedures involve characteristics of both restrictive and malabsorptive procedures.
Gastric bypass surgeries are combination procedures that use both restriction and malabsorption to achieve weight loss.
Because it is a combination approach, it tends to be more successful for weight loss than purely restrictive surgeries. However, your body may not absorb vitamins and minerals properly.
Restrictive-only procedures are not as successful. It is easy to "cheat" and eat too much food, over-stretching the newly created stomach pouch.
