ObjectiveThis study aimed to analyze the correlation between different attributes of doctors who prescribe colonoscopies and the cleanliness of the intestine to guide the development of colonoscopy application protocols.MethodsData on colonoscopy cases conducted in the gastroenterology department of Hangzhou First People's Hospital between April 2018 and March 2021 were collected. The gender, age, professional attributes of the prescribing doctors, and Boston Bowel Preparation Scale (BBPS) score were recorded. In addition, the correlation between the prescribing doctors' characteristics and the intestine's cleanliness was analyzed.ResultsThe study included 22,522 patients with a mean BBPS score of 6.83 ± 1.94. There were 16,459 male and 6,063 female doctors with similar BBPS scores (p = 0.212). The study found no significant difference in BBPS scores between 19,338 internist and 3,184 non-internist (p = 0.154). However, BBPS scores differed significantly between 18,168 gastroenterologists and 4,354 non-gastroenterologists (p = 0.016) and between 19,990 intestinal-related specialties(gastroenterology and gastrointestinal surgery) and 2,532 non-intestinal-related specialties (p = 0.000). In addition, BBPS scores were significantly different between 18,126 prescribing endoscopiests and 4,396 non-endoscopiests (p = 0.014). However, there was no significant difference in BBPS scores among doctors of different ages (p = 0.190). The study found significant differences in BBPS scores between male and female patients and those under or over 40 years (p = 0.000).ConclusionTo improve colonoscopy preparation quality, priority should be given to doctors in gastroenterology, intestinal-related specialties, and endoscopiests. Their expertise may result in better education and improved bowel cleanliness.
