A number of news reports in the last few weeks have drawn attention to the involvement of private equity firms in health care companies, particularly nursing homes. Now comes news that Congress wants to look into the situation. Senator Hillary Clinton of New York, a Democrat, and Republican Senator Charles Grassley of Iowa have asked Congress to investigate the situation.

The source of the growing concern about care at for-profit nursing homes owned by private equity firms is an article in The New York Times published in September. The title of the article sums up the situation pretty well: "At Many Homes, More Profit and Less Nursing." It seems that when private equity gets involved in providing nursing care, more money goes toward making investors comfortable and less toward the elderly folks who actually live in the facilities.

I doubt that too many readers will find this claim surprising. Private equity funds search for return on investment. If a couple thousand old people live a little less comfortably, or die a little sooner -- well, too bad. Profits must be made, and the higher the better. What may come as a surprise, though, is the size of this market. For example, the Carlyle Group plans to buy Manor Care Inc. (NYSE: HCR), the largest U.S. nursing home owner, for $4.9 billion. That's an awful lot of bedpans.

And it turns out that private equity firms are ideally suited to run these operations -- assuming that what you want is the highest possible profit rather than, say, excellent care for the elderly. Private equity excels at wringing out costs, and so has no trouble firing many of those expensive nurses who take care of the patients. Private equity also loves to create debt and ownership structures so complex that no one can figure out who actually owns a business -- thus shielding the owners from lawsuits. And the nursing home business deals with a powerless group of consumers, many of whom are subsidized by government payments. No wonder private equity firms are jumping into the sector! Just hope that your elderly relatives stay healthy and strong.
