Shirley Carlton

I have an administrative background starting in the private sector and moving to work in an NHS Trust where I worked for about 20 years. I have enjoyed a range of roles, spending much of my time analysing data and providing information for local and national benchmarking and projects. I had the unique opportunity to work with Jean and Marie when they were producing the manual; my main input was to help with the format of the content and layout for the book [several draft versions !] whilst gaining some insight into the methodology and calculations for staffing … from there Birthrate has developed into the company it is today and I am delighted to have seen the developments of both the workforce and acuity programmes
