Key performance measure	Patient experience
Description	Patient experience during and after colonoscopy and sigmoidoscopy should be routinely measured and self-reported by patients using validated scales.
Domain	Patient experience
Category	Outcome
Rationale	Colonoscopy can be an unpleasant experience. Moreover, there are considerable differences between endoscopists and between different sedation modalities with regards to patient-reported pain and discomfort.
	Patient experience and its improvement is crucial for the acceptance of procedures.
Construct	Denominator: All colonoscopies
	Numerator: Procedures in the denominator in which patient experience was measured using a validated scale (the Global Rating Scale, the Gastronet, or others)
	Exclusions: Emergency colonoscopies
	Calculation: Proportion (%)
	Level of analysis: Individual endoscopist and service
	Frequency: Continuous monitoring using novel endoscopy reporting systems should be the preferred approach;12 an alternative approach is a yearly audit of a sample of 100 consecutive LGI endoscopies.
Standards	Minimum standard: Unknown
	Target standard: ≥90%
	Currently there is no standard approach to measuring patient experience: different questionnaires are available and their comparative performance is unclear. Ideally, patient experience should be self-reported using a standardized and validated reporting method.
	Audits should be performed on both service and individual endoscopist level to assess patient-reported outcomes.
	In case of substandard results (for example if one endoscopist performs worse than others in the same service), additional training and feedback should be considered.
