North Yorkshire and York PCT to review recruitment procedures
The way North Yorkshire and York Primary Care Trust recruits staff is to be reviewed.
It follows a report which revealed out of 861 applications from people with a black or ethnic minority background, only five were employed in 2011.
The review will examine how jobs are advertised and how candidates are shortlisted and interviewed.
The trust said it had "robust" equality and diversity policies and the review was to ensure they were being followed.
Amanda Wilcock, associate director of human resources at NHS North Yorkshire and York, said: "The statistics in the Equality and Diversity Report show a significant improvement on the previous year.
"However, board members were concerned at the perceived discrepancies highlighted in the report."
Figures for April to October 2011 showed candidates from black or ethnic minority backgrounds represented 22% of all job applicants but only 8% of successful candidates.
The applications related to both medical and non-medical vacancies.
Ms Wilcock said there were some factors that could influence recruitment figures such as applications from individuals abroad not eligible to work in the UK.
She said the review would explore why minority candidates who were eligible had not been shortlisted or appointed.
