Aims Identify specific risk factors for prolonged colonoscopy in an outpatient endoscopy unit. Correlate results to optimise time management in endoscopy units

Methods Prospective survey cohort: 45 patients (15 male, 30 female)

Data retrieval: 4 prong approach

  • Patient questionnaire (identify patient specific risk factors)

  • Quantitative analysis document (measure total procedure time (TPT), caecal intubation time (CIT), withdrawal time (WT), Number of polyps identified/resected), Number of biopsies

  • Bowel preparation measurement tool (Boston Bowel Preparation Scale (BBPS))

  • Endoscopist questionnaire (identify experience in colonoscopy i.e. Number of procedures conducted)

Results Endoscopist experience has an impact on TPT (P =  0.003, Eta2= 0.247).

Experienced endoscopists had on average a TPT 50 % shorter than their less experienced counterparts. Experience was segregated based on number of procedures performed (<100, 100-500, 500-1000, >1000)

The following were also identified as impacting on TPT

  • Polyp detection (P =  0.001, Eta2= 0.233)

  • Number of polypectomies per procedure (P =  <0.0001, Eta2= 0.436),

  • Number of biopsies (P =  0.026, Eta2= 0.166).

Bowel preparation grade (according to Boston Bowel Preparation Scale) has an impact on CIT (P =  0.03, Eta2= 0.241) with an inverse relationship between duration and BP grade.

Conclusions To clear the backlog facing endoscopy units a transient change may be required. The single greatest modifiable risk factor is endoscopist experience. Therefore, movement of experienced endoscopists into a strict procedural role may be suitable temporarily or the employment/training of more nurse specialists to fulfil the gap. Also, strict bowel cleansing agent compliance must continue to be encouraged.
