Compare the Patient Satisfaction and Effectiveness After Novel Application-based or Conventional Health Education of Bowel Preparation for Colonoscopy

Compare the Patient Satisfaction and Effectiveness After Novel Application-based or Conventional Health Education of Bowel Preparation for Colonoscopy-- Randomized Controlled Trial

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.
