> The recently published RAND Wellness Programs Study, which included almost 600,000 employees at seven employers, showed that wellness programs are having little if any immediate effects on the amount employers spend on health care. This has been further confirmed by our new analysis of 10 years of data from a Fortune 100 employer. They're looking at seven enormous employers. Can their findings really be applied to all employers? There's a lot of variance between employers (average salary, average age of employees, region where employees are based). I'm not sure that you could reasonably compare employees at, say, WalMart, with employees at Goldman Sachs or Google. There's also presumably a lot of variance between these different programs. Is it possible that some programs are just badly executed?
