Supply and quality of colonoscopy according to the characteristics of gastroenterologists in the French population-based colorectal-cancer screening program

Table 1 Evolution of the regional offer in number of gastroenterologists and the number of gastroenterologists having performed at least one colonoscopy, by year of performance of the screening colonoscopy

Year of colonoscopy	Nb of GE in IDF1		Number of gastroenterologists who performed a screening colonoscopy2
			Number of GE by seniority		Number of GE by density of GE in the municipality of practice of the GE			Number of GE by place of performance of the colonoscopy			Number of GE by annual number (A) of colonoscopies performed				Total (n) of GE in IDF (% GE ≥ 2 location)
	Nb of GE (density)3	Nb of municipalities with GE	Senior	New (% in n)	Low	Average	High	Private clinic	Private Hop.	Public Hop.	A = 1	A = 2-30	A = 30-100	A > 100

¹Number of gastroenterologists (GE) registered in the region (source: National Council of the Order of Physicians).

²Number of gastroenterologists who performed a screening colonoscopy during the calendar year (regardless of the type of test and regardless of the date of the screening test).

³Density in Number of GE/100000 inhabitants: Regional average density (5.5 à 7.5 GE/100000 inhabitants) Low density of GE (< 5.5 GE/100000 habitants) and high density of GE (> 7.5 GE/100000 inhabitants).
