Background:
The introduction of the Bowel Screening Programme (BSP) came with a focus on high-quality endoscopy. This was supported by open reporting and feedback of quality performance indicators (QPIs) to endoscopists. The aim of this study is to describe any changes in QPIs of colonoscopies for non-screening, symptomatic patients following the introduction of the BSP.
Methods:
A 3-year retrospective study was performed of non-screening, symptomatic patients undergoing colonoscopy before (pre-BSP) and after (post-BSP) implementation of the BSP. The primary outcome was the change in the polyp detection rate (PDR).
Results:
Totally, 4396 patients were identified; 2238 in the pre-BSP group and 2158 in the post-BSP group. There was no significant difference in demographic factors between groups. The adjusted PDR significantly increased from 45.5% in the pre-BSL group to 51.9% in the post-BSL group (p < 0.001). A significant increase in polypectomy rate and adequate withdrawal times was found in the post-BSP group.
Conclusion:
This study found a significant improvement in QPIs, including PDR, in patients undergoing colonoscopies for symptoms following the introduction of the BSP in Te Tai Tokerau. This suggests an indirect improvement in the quality of all colonoscopies being performed in hospitals that participates in the BSP.
