Endoscopic skill domain summary
| Domain | Endoscopic skill |
|---|---|
| Objective | Assessment of endotherapy success |
| KPI | Recurrence/residual polyp at 12 months in endoscopically managed LNPCPs |
| Denominator | Include all patients undergoing 12-month surveillance after resection of LNPCPs. Recurrent/residual polyp identified and cleared before 12-month surveillance does not warrant inclusion within this parameter. As not all surveillance will occur on schedule, allow up to 15 months for surveillance to occur. Only count the first surveillance at or after 12 months. Exclude patients who do not have surveillance within 12–15 months (owing to surgical resection, death, comorbidity, emigration, etc). NB—monitor this figure to ensure surveillance recall process is robust |
| Numerator | Patients undergoing 12–15-month surveillance with endoscopic or histological evidence of polyp recurrence at the site of resected LNPCP |
| Analysis | Calculate at LNPCP level Report as percentage (proportion of LNPCPs with recurrence on 12-month surveillance) |
| Frequency | Calculate annually |
| Level of analysis | Service and individual colonoscopist level |
| Minimum standard | <10% |
| Aspirational standard | <5% |
| Action | Qualitative review of each case |
| Evidence | Supporting evidence: Belderbos et al112 Moss et al9 Barendse et al58 Khashab et al169 Knabe et al170 Supporting evidence for quality standard Lee et al7 Longcroft-Wheaton et al29 |
