Large Overuse of Post-polypectomy Surveillance Colonoscopy

Completed

• Conditions: Colonic Polyps; Surveillance; Colonoscopy
• Interventions: Other: colonoscopy

• Registration Number: NCT01458093
• Lead Sponsor: Valduce Hospital

Brief Summary

In colorectal cancer screening era a huge burden of medical resources has been applied to surveillance. Although the adherence to post-polipectomy recommendations is a advocated as a mainstay for quality assurance colonoscopy programs, prospective data on appropriateness of surveillance are lacking.

The aim of present study was to evaluate the percentage of subjects in which timing of surveillance colonoscopy in practice agrees with that recommended by guidelines and to identify factors associated to the appropriateness of surveillance.

Arm && Interventions

Group	Intervention	Description
Colonoscopy patients	colonoscopy	Consecutive colonoscopy outpatients referred to one of 29 endoscopy units in Italy

Primary Outcome Measures

Name	Time	Method
Adherence to post-polypectomy surveillance guidelines	up to one year	Time interval between index and surveillance colonoscopies for patients undergoing post-polypectomy surveillance was calculated and compared to that suggested by the guidelines according to endoscopic findings at previous examination. For each patiens, surveillance time interval was regarded as correct if coherent with the recommended interval +/- 6 months, thus allowing to calculate the proportion of correct prescriptions

Secondary Outcome Measures

Name	Time	Method
Factors associated to surveillance appropriateness	up to one year	The presence of factors associated to appropriate surveillance prescriptions was investigated by multivariate analysis (odds ratio and 95% confidence interval for each factor)
