Veterans hospitals are struggling to replace hundreds of doctors and nurses who have left the health care system this year as the Trump administration pursues its pledge to simultaneously slash Department of Veterans Affairs staff and improve care.

Many job applicants are turning down offers, worried that the positions are not stable and uneasy with the overall direction of the agency, according to internal documents examined by ProPublica. The records show nearly 4 in 10 of the roughly 2,000 doctors offered jobs from January through March of this year turned them down. That is quadruple the rate of doctors rejecting offers during the same time period last year.

The VA in March said it intended to cut its workforce by at least 70,000 people. The news sparked alarm that the cuts would hurt patient care, prompting public reassurances from VA Secretary Doug Collins that front-line health care staff would be immune from the proposed layoffs.

Last month, department officials updated their plans and said they would reduce the workforce by 30,000 by the end of the fiscal year, which is Sept. 30. So many staffers had left voluntarily, the agency said in a press release, that mass layoffs would not be necessary.
