The quality of endoscopic examinations substantially determines their value. In developed countries, Continuous Quality Management is used to improve it permanently. In Hungary there is no example for measuring quality in the field of gastrointestinal endoscopy.
Aim: The measurement and improvement of quality of endoscopy applying completeness index (cecum intubation rate) during colonoscopy.
Patients and methods: The authors defined base values retrospectively from 841 colonoscopy reports, performed in the last quarter of the year, before starting the project. The next two years (3160 colonoscopy in 2009 and 3167 in 2010) every three months they calculated the cecum intubation rate for each endoscopist.
Results: The cecum intubation rate was 81.6% in the base period. When the authors excluded examinations with poor preparations and those with a previously unknown stenosis that prevented the total colonoscopy, the adjusted cecal intubation rate was 90.9%. In the next 2 years, the cecum intubation rate was 84.2% and 85.7% (p = 0.0394), while adjusted cecum intubation rate proved to be 92.3% and 92.6% (p = 0.381 NS) for the whole endoscopy unit. Of the 14 endoscopists only 6 reached an adjusted cecum intubation rate of 90%, but in the second year of the project 10 of them reached this rate and only one endoscopist remained below 87%. The endoscopists performing more than 100 colonoscopies per year had better adjusted cecum intubation rate (base 91.2%; 92.7% and 93.1% during the 2 project years) compared to those with less than 100 colonoscopies per year (base, 86.7%; project period, 85.5 and 89%).
Conclusions: The evaluation and publicity of the cecal intubation rate resulted in an improvement of the quality of colonoscopy. The authors also presented that endoscopists performing more than 100 colonoscopies per year have better endoscopic quality.
