Create GRS metrics by endoscopist (X-ref with pathology)
Source:R/Module_Polyps.R
GRS_Type_Assess_By_Unit.Rd
This extracts the polyps types from the data (for colonoscopy and flexible sigmoidosscopy data) and outputs the adenoma,adenocarcinoma and hyperplastic detection rate by endoscopist as well as overall number of colonoscopies. This will be extended to other GRS outputs in the future.
