Barber-Johnson diagram

In 1973 Barber B. and Johnson D. presented a paper entitled "The Presentation of Acute Hospital In-patient Statistics" in the Hospital and Services Review. This paper started an innovative way of presenting hospital statistics by mean of combining four different variables in a unique graph. The method allowed to construct a scattergram where length of stay, turnover interval, discharges and deaths per available bed could be combined. These 4 variables have a common relationship between them and their combination in the diagram permitted a new improved way for analyzing efficiency and performance on the hospital sector.The most complete reference about how to construct the diagram could be find in Yates, John (1982). Hospital Beds. A problem for diagnostic and management?. In this book, the appendix explains in detail the way for elaborating this kind of diagrams.Useful references could be find on the web under: [http://www.publichealth.pitt.edu/supercourse/SupercoursePPT/7011-8001/7891.ppt] [http://eurpub.oxfordjournals.org/cgi/reprint/9/2/103.pdf]
