I am preparing monthly the radiologist percentage of compliance with a standard on reporting TAT. I have easy access to all data thru our RIS and so there is no sampling. Despite absence of sampling error, can we use control chart to detect trends, for example by using control chart for individuals and moving range.
I know it looks not logical, but accreditation bodies have more confidence if the results are presented as control charts
