The deputy secretary of the Department of Veterans Affairs says the troubled Central Alabama Veterans Health Care System has made significant improvements, but there is still progress to be made. Deputy Secretary Sloan Gibson says the wait for an appointment is still too lengthy at the Montgomery-area facilities. He says additional personnel actions might also be taken after the system's director was fired earlier this year. He says investigations into allegations of retaliation against whistle-blowers are ongoing. He says he wants to create a workplace where employees feel encouraged to report problems. Gibson on Monday met with managers and employees at the Tuskegee and Montgomery facilities. Gibson says the hiring of additional doctors, new management and training for staff will improve the care to veterans.
