Introduction :
Colorectal Cancer (CRC) is the second most common cancer in Hong Kong. The government launched the CRC Screening Programme in 2016 for asymptomatic Hong Kong resident aged 50 to 75 to undergo screening tests for prevention of colorectal cancer. Participants with a positive faecal immunochemical test (FIT) were subsided to undergo private colonoscopy. People with colonic adenomas are at increased risk for recurrent adenomas and thus eventually colorectal cancer. As part of this initiative, a nurse-led colonic polyp clinic was developed at KWC and HKEC in 2016 to provide health education and support to individuals with colonic polyps and ensure the continuity of care after colonoscopy. The first consultation was shorten from 18 months to 3-4 months.
Objectives :
The study aims to assess patients’ self-perceived knowledge on colonic polyp and the result of surveillance colonoscopy after attending the nurse-led colonic polyp clinic.
Methodology :
Patients participated in this survey were those who had 1) received polypectomy from April 2017 to March 2020 under the government-subsided CRC Screening Programme, 2) high risk adenoma with recommended surveillance colonoscopy at an interval of 3 years or less and 3) attended nurse-led colonic polyp clinic with provision of health education. Results were collected on 1) a 5-point Likert scale, which ranged from "strongly disagree" to "strongly agree" and 2) Clinical Management System.
Result & Outcome :
From October 2022 to March 2023, 200 patients at KWC and 114 patients at HKEC participated in this survey. Of 314 respondents, 119 were females and 195 were males with a mean age of 65. Majority of respondents agreed or strongly agreed that they knew the causes of colonic polyp (95%), symptoms of colonic polyp (96%) and the recommended time interval for the next surveillance colonoscopy (92%) and healthy dietary habit and regular physical activity as protective factors to reduce the risk of colonic polyp (94%).
In surveillance colonoscopy, 60.2 % patients without recurrence of colonic adenoma and 32.2% patients with 1-2 low risk of colonic adenoma.
The survey demonstrated that majority of respondents had good perceived knowledge on colonic polyps through provision of nurse-led health education. It is recommended that continuation of health education to be conducted for patients who had received colonoscopy for high-risk adenoma under the government-subsided CRC Screening Programme.
