A government probe of delays in veterans’ health care has confirmed systemic scheduling abuses and cover-ups. In one of the 42 veteran health centers now being investigated, the department’s inspector general discovered that the average waiting time for initial primary care was 115 days — nearly five times what the hospital’s administrators reported. Delays were likely to have been hidden to falsify better performance reviews for hospital personnel, it said. The information has been turned over to the Justice Department. The report has prompted renewed calls for the resignation of Veterans Affairs Secretary Eric Shinseki.
