Colorectal cancer is the cancer with highest incidence in Taiwan. The disease itself and
subsequent treatment cause huge impact on the physical, psychological, and spiritual
parts and social role of a patient. Early diagnosis of colorectal cancer and precancerous
lesions is possible. Early treatment can reduce the impact on quality of life and
economics.
Colonoscopy is an important tool for diagnosis of colorectal proliferative lesions.
Qualified bowel preparation can enhance sensitivity and reduce false negative of the
colonoscopy. However, multiple factors influence the quality of bowel preparation. This
study aims to investigate whether the animation video and game-based health education is
more effective and satisfying than conventional health education, and to explore the
difference of knowledge dissemination and quality of bowel preparation between novel and
conventional methods.
This study is a randomized controlled trial and uses structural questionnaire for study
participants. Before the main study, the investigators will consult professors' opinions
to adjust and enhance validity of the questionnaire, and the investigators will perform
pretest to calculate its reliability. The investigators will enroll participants at the
out-patient-department and the health management center. Questionnaires may be completed
by on-site paper or phone with internet resources. The main participants of this study
are adults aged 18 and more, and planned to receive colonoscopy. The questionnaires
investigate the spent time, patient satisfaction, knowledge of bowel preparation and
results of colonoscopy of different approaches of health education. Multiple linear
regression will be applied to calculate the possible significance difference between two
kinds of health education.
The investigators expect this study (1) to explore whether novel health education
enhances patient satisfaction (2) to investigate the efficiency of novel health
education, and (3) to compare the effect of knowledge dissemination and quality of bowel
preparation between experimental and control groups. This study will develop the model of
health education to facilitate holistic health care.
