Calculating of Correlations Between ADR, PDR, MAP

ADR (adenoma detection rate) is generally accepted quality indicator. For possible gaming with ADR other indicators are needed. MAP (mean adenoma per colonoscopy) reflects the quality of examination of entire colon and is considered to be the most objective quality indicator. The aim of our study is to compare MAP with ADR and PDR (polyp detection rate) of all colonoscopists in our department.

We want to retrospectively assess the quality indicators of all colonoscopies from January 2013 to December 2017. We want to calculate ADR, PDR and MAP of all our endoscopists for all colonoscopies in patients over 50 years of age excluding therapeutic, IBD, management of complications and sigmoidoscopies (screening, surveillance, diagnostic) and separately only for screening colonoscopies. Correlations between MAP/ADR and MAP/PDR will be performed using Pearson´s correlation coefficient.
