During the first presidential debate Wednesday night, the candidates talked a lot about how they would lower the cost of your medical care.

Heavy on data and large numbers, the debate may not have been the easiest to follow for Americans interested in the subject.

Ken Thorpe, an Emory University economist who specializes in health care costs, may have been one of the few excited by all these numbers.

"It was about as substantive a debate as I think we've ever seen," Thorpe said. "The problem is, even after this debate, I don't think people truly understand the similarities and the differences in what these candidates are proposing for health care."

Here are five things you should know about what the candidates said about health care in last night's debate:

1. You do pay more for health insurance, but Obama's policy isn't totally to blame.

The first mention of health care came about six minutes into the debate. Discussing how "middle-income Americans have been buried" financially under the president's policies, Republican challenger Mitt Romney said health care costs have gone up by $2,500 a family.

Each year, health care costs have gone up during Obama's administration -- that is true. But experts say the increases have not been due to policy, but because of the rising cost of health care. The figure Romney used is not quite right.

The Kaiser Family Foundation, which conducts an annual survey of health care costs, found that since 2008 the average family premium has gone up about $1,698. For context, that is the total cost that you and your employer pay -- it's not $1,698 out of your pocket. In fact, the report said the increase you personally pay was not "statistically significant."

Rising health care costs are a significant problem, though. The same survey found that the average premiums for family coverage have increased a whopping 113% since 2001. That means the trend started long before President Barack Obama took office.

2. Medicaid and Medicare fraud is a huge problem and more needs to be done.

Obama's first specific reference to health care described how the administration pursued medical fraud in Medicare and Medicaid "more aggressively than ever before," which saved the system tens of billions of dollars.

Medicare and Medicaid fraud is what one expert called "one of the most profitable crimes in America." It costs taxpayers billions of dollars annually -- $60 to $90 billion a year, based on government estimates. That's money that could be better spent on taking care of actual health care costs.

Historically, it was up to states to police this problem, but the fraud grew too big for them to handle. A Republican-backed bill called the Deficit Reduction Act of 2005 created the Medicaid Integrity Program, which gives the federal government the ability to oversee and support states' anti-fraud efforts.

The Obama administration launched several key programs to protect against fraud. They have saved taxpayers billions; however, a Government Accountability Office investigation concluded that while progress has been made under Obama, more could be done.

In a report this June, in fact, it found at least one of the major programs -- an audit conducted by the government -- costs taxpayers $102 million, but only found $20 million in excess payments.

"They have certainly been increasing their work in this area," Thorpe said. "A certain kind of focus definitely did help eliminate some of this fraud."

3. Sending Medicaid back to the states would save the federal government money, but cost states more and adversely impact those using the benefits.

Obama criticized Romney's idea of sending Medicaid back to the states. He argued that this would mean a "30% cut in the primary program (for) seniors who are in nursing homes, for kids who are with disabilities."

The plan GOP vice-presidential candidate Paul Ryan, as the head of the House Budget Committee, suggested in April -- which Romney adopted as his own -- would cut $1.4 trillion in Medicaid in the next 10 years. It would accomplish this by converting the program into a block grant that would in large part shift costs to the states, which Romney argued would give states more flexibility to do what they deem best to help their Medicaid population.
