Up to 200 trainee doctors hoping to plug Australia's yawning doctor shortage could have their careers terminated by a bungle that has denied them ongoing positions in Victorian hospitals.

Late on Monday, hundreds of first-year interns discovered that a controversial computer matching system had knocked back their applications for a permanent gig, effectively leaving them out of a job. This morning, rumours were sweeping the state's hospital wards that the mismatch between applicants and positions was at least 160, and could top 200.
