Bariatric Surgery is not only for the treatment of people who are severely overweight, but also for those who are slightly obese cost-effectively according to new research from Washington University School of medicine in St. Louis. The researchers say the results support to access bariatric surgery all obese people.
Patients who have the surgery are more likely to hold weight in the course of time and have less medical problems relating to their weight on it, that the procedure is a good value. But not more low-cost, shows that actually stores analysis, bariatric surgery health dollars for most severely overweight patients, who have weight also diseases such as diabetes, heart disease and high blood pressure.
Su-Hsin Chang, PhD, a postdoctoral research staff in the Division of public health sciences and primary author of the study published in the journal of Maturitas says "If life account for medical costs, surgery severely overweight patients saves money,".
National institutes of health (NIH) policy say that candidates for bariatric surgery a body mass index (BMI) of 40 or more (about 100 pounds overweight for men and 80 pounds overweight women on average), or a BMI of 35 to 40 should have, if they have diseases also obesity-related. Many insurance companies pay for the procedure only if patients meet those criteria.
"Insurance companies often pay for the treatment of obesity related diseases," says Chang. "But a part of these costs could be saved if she paid bariatric surgery for a wider range of obese patients."
Among the many strategies for the treatment of obesity, including diets, exercise and drugs only bariatric surgery showed that maintaining a healthy body weight in the long term effect. But even surgery is the most expensive strategy. Cost estimates range from $20,000 $ 25,000 for the first operation and aftercare included none.
Low-cost is the upper limit for medical treatment in the United States be taken into account $50,000 per Qualitätskorrigiertes year (QALY), a measure of the true value of the treatment of a person, the quality and length of life. The assumption is that most people would be willing to pay up to $50,000 for a further year of healthy life. Each be less than, which is considered low-cost.
Chang and her colleagues analyzed data from 170 studies in view of the efficacy of bariatric surgery. The analysis included only studies that measured the at least a result of interest such as weight loss, quality of life, complications and medical cost information.
They used this data value and life expectancy and the quality of life of people, subjected the surgery when compared to people not to simulate that. This simulation data then informed their cost effectiveness analysis.
For the super obese, people with a body mass index (BMI) of 50 or higher (such as a person, the 350 weighs and is 5 feet 10 inches tall), the cost per Qualitätskorrigiertes age is actually negative. This means that the cost of bariatric surgery for a lifetime with is less than the health costs associated with the process.
For heavily overweight people with BMIs 40-50, the cost per QALY is about $1,900 for those with obesity, disease, and about $3,800 for those who are otherwise healthy. And for the moderately obese people with BMIs of 35-40, per QALY costs about $2,400 for those with appropriate medical problems and $3900 for those who are healthy. While the cost of healthier, less overweight patients increase, are all amounts well below the threshold level of $ 50,000.
"Other similar studies found higher costs associated with bariatric surgery have, because they not the lifetime medical costs of diseases related to obesity to take into account," says Chang.
This work differs from previous cost investigations because it pulls data from a much larger number of studies. While Chang that bariatric surgery generally is the high price tag says, points out that the analysis not distinguish between types of bariatric surgery, Lap Band and gastric bypass.
"We do not compare of various types of weight loss surgery, but their effects and costs to generalize intention", she says. "Based on our analysis, bariatric surgery an option that is universally available to all obese people available should."
