The U.S. lags behind other nations in several areas of health care, according to a study by Kaiser Family Foundation. 

But the variance in health care quality also holds true when it comes to the nation's states.

WalletHub compared the 50 states and Washington, D.C., on health care cost, consumer access and patient outcomes and ranked them based on a 100-point scale.

In addition to identifying the states that offer the best overall health-care services, the ranking also inevitably identified states that were at the bottom of the list.

Health insurance, out-of-pocket expenses and typical doctor visit costs were measured to determine the cost category, while patient outcomes measured mortality rates and disease risks. The "access" category measured availability to health-care clinics, quality of hospitals and doctors per capita.

These are the worst states for health care, in descending order, according to WalletHub:

10. Florida

Florida had among the lowest percentage of adults and children who were insured, ranking 50th for adults aged 18 to 64 and 47th for children. Overall, the state scored a 47.04.
