Introduction Significant colonic polyps are a recognized risk factor for colorectal cancers. Follow-up colonoscopies at intervals guided by initial colonoscopy findings are recommended for patients with significant polyps, by the NHMRC guideline. However, over-servicing is a common issue, and studies have shown that up to 40% of polyp surveillance colonoscopies are performed earlier than the recommended guideline. Methods We audited the polyp surveillance colonoscopies performed from the 1st January 2018 to the 30th September 2020 in the three public hospitals in Central Queensland. We extracted colonoscopy intervals from the collected data and compare them against the guideline in effect at the time of the colonoscopy. Results 56% (95CI 48-63%) of the surveillance colonoscopies were performed earlier that the recommended surveillance intervals. The mean and the median number of days earlier than the Guideline were 550 days and 541 days. Conclusion Marked over-servicing was found. Staff designated to organise polyp surveillance is recommended to avoid too short surveillance.
