Nearly three years into a Medicaid privatization program former Gov. Jeb Bush said could be a national model, Florida officials say they do not have crucial data to measure the program's effectiveness, including how many patients' treatments and prescriptions have been approved or denied. Patients and healthcare advocates have complained they can't get doctors appointments and medications under the program. An Associated Press study found nearly 25% of doctors in Broward and Duval counties have dropped out because of red tape and an inability to treat patients as they see fit.
