Nurse-led Decision Counseling on Hepatocellular Carcinoma Screening

Participants in the intervention group will receive the following three-week, three-session intervention. The details are as follows.

Education (20 min). At first week, education will be delivered through face-to-face for the following information: (1) HBV infection and increased HCC risk; (2) HCC screening recommendations regarding eligibility, available screening tests and recommended screening intervals; (3) pros/advantages of undergoing HCC screening; (4) cons/disadvantages or uncertainties of undergoing HCC screening; (5) implications of positive screening results; and (6) health costs. The education material will be present in a self-made manual, which will be explained and distributed to each participant.

Tailored psychosocial information (20 min). It will be conducted after education. The tailored messages will be developed to form a message library for each sub-scale of the preventive health model instrument with scoring ≤ 3 and > 3. The contents will be based on HCC screening guidelines and recommendations. The nurse counsellor will select and explain tailored information based on individual's responses to the preventive health model instrument.

Values clarification exercises (30 min). At the second week, the decision counselor will work with participants through telephone-based way to go through values clarification exercises, in which participants will: (1) review the listed pros and cons decision factors of undergoing HCC screening one by one; (2) indicate the extent to which each pros and cons matters to them by giving stars; (3) add any other reasons for choosing or not choosing HCC screening and indicate their importance; and (4) indicate their decision preferences toward undergoing HCC screening, unsure, or not undergoing HCC screening.

Exploring and addressing implementation barriers (20 min). At the third week, the decision counselor will work with participants, through telephone-based ways, to explore possible barriers to undertake HCC screening; identify possible solutions or available resources to the identified barriers via brainstorming; and encourage implementation of the chosen solution to overcome the barriers and schedule for HCC screening.
