Colorectal Web

An Evidence-Based Practice

Description

Colorectal Web is an interactive electronic tool promoting colorectal cancer screening. The website presents information on colorectal cancer and various screening options, and is designed to help adults aged 50 or older choose a preferred method of screening. The website uses a simple design with limited text and an emphasis on graphics. Users select and rank three variables that they consider when choosing a screening approach. The preference variables include cost, discomfort, embarrassment, frequency, inaccurate results, inconvenience, need for additional tests, preparation for test, risk, and sedation. The program uses these variables to recommend a screening test that best matches the user's preferences. After the user selects a screening method, they view a video clip of a doctor encouraging them to complete their selected screening.

Goal / Mission

The goal of the Colorectal Web interactive website is to promote colorectal cancer screening.

Impact

Colorectal Web is more effective than a standard colorectal cancer website at prompting previously unscreened individuals to choose a preferred colorectal cancer screening test and to be screened for colorectal cancer.

Results / Accomplishments

In a randomized controlled trial of 174 participants, Colorectal Web users were compared to a control group that used an existing non-interactive colorectal cancer website. Immediately following the intervention, Colorectal Web participants were significantly more likely to have selected a preferred colorectal cancer screening method when compared to the control group (p < 0.0001). At the 24 week follow-up, the Colorectal Web intervention group was significantly more likely to have been screened than the control group (p = 0.035).

An Evidence-Based Practice meets the following HCI criteria:

  1. The program description includes at a minimum: the sponsoring organization, program goals, program implementation steps, and outcomes that have demonstrated program success in achieving the program goal in one or more localities.
  2. The results from an evaluation of the program include quantitative measures showing improvement in the outcome(s) of interest after the implementation of the program (i.e. increase in smoking cessation, not just the delivery of a smoking cessation program). The outcome measure(s) is/are compared at relevant time periods before and after the intervention or program implementation. Alternatively, the evaluation study compares the outcome(s) between an intervention group and an appropriate control group.
  3. The study is of peer-review quality and presents numbers in a scientific manner; measurements of precision and reliability are included (e.g. confidence intervals, standard errors), results from statistical tests show a significant difference or change in the outcome measure(s), and relevant point estimates and p-values are presented. Note: if the results from an evaluation of a program are presented in a scientific manner and the outcome measure is improved compared to the baseline measurement or the control group but the difference is not statistically significant, the practice is classified as effective and not evidence-based.
