A number of Miami-area doctors are complaining about the way HCA Holdings officials have ended their employment with the hospital giant. In addition to facing a big pay cut and/or a short time window in which to close down their practices, they say HCA's big physician recruiting push in recent years isn't working as well operationally as had been promised. The company said the doctors' exits are a normal business decision, but a former exec says the doctors' gripes could be a sign of bigger problems.

Curtis, who left HCA in 2010, said that HCA’s physician practices “just grew too fast,” hiring hundreds of doctors a year, and didn’t have the infrastructure to support them at its headquarters in Tennessee. “There were huge delays in getting claims, credentialing, and it just went on and on. It was not a well orchestrated process. Now they’re at a stage where they’re cutting doctors to reduce their losses.”
