Figures obtained by ITV Border have found that the North Cumbria Health Trust spent 8 million pounds in the past year on temporary doctors.
The so called locums are being relied upon because the troubled trust is struggling to recruit experienced doctors.
The Freedom Of Information request also found that one consultant was being paid £158 an hour.
One local MP has branded the figures 'astonishing'.
The trust says it will cut the number of locums used by 50%.
