Large Overuse of Post-polypectomy Surveillance Colonoscopy
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.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Large Overuse of Post-polypectomy Surveillance Colonoscopy: a Prospective Nation-wide Study|
- Adherence to post-polypectomy surveillance guidelines [ Time Frame: up to one year ] [ Designated as safety issue: No ]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
- Factors associated to surveillance appropriateness [ Time Frame: up to one year ] [ Designated as safety issue: No ]The presence of factors associated to appropriate surveillance prescriptions was investigated by multivariate analysis (odds ratio and 95% confidence interval for each factor)
