Systematic Review of Colorectal Cancer Screening-Related Apps.

Background: In the United States, colorectal cancer (CRC) is the second leading cause of cancer death in men and women combined. The United States Preventive Services Task Force recommends that average risk adults have regular CRC screening to detect and prevent CRC. Despite published CRC screening guidelines, national CRC screening rates remain suboptimal. With the exponential increase in technology use and device ownership, many mobile health applications (apps) have been developed to improve health outcomes. There is great potential for smartphone or tablet apps to help improve CRC screening uptake, with the ultimate goal of reducing CRC morbidity and mortality. To date, there are no systematic reviews that have examined the publicly available, free apps that are related to CRC screening, and therefore, the quality and the content of these apps remain unknown. Objectives: The purpose of this study was to systematically review smartphone and tablet apps that could be used to improve CRC screening uptake. Methods: Apps available on the Google Play and Apple App stores that were compatible with smartphones and tablets were reviewed. Of the 2,790 apps reviewed, 20 met inclusion criteria. Results: Of the 20 apps that met inclusion criteria, most were informational in nature. Approximately half of the apps focused on colonoscopies and did not discuss other CRC screening options. Furthermore, more than half of the apps did not include video/audio content and the majority of the apps did not provide navigation support (e.g., reminders, instructions, maps). Conclusions: There are multiple free, publicly available apps that may encourage CRC screening uptake. Despite their promise, there is a paucity of empirical evidence evaluating the efficacy and usability of these apps. Future research efforts can evaluate the content, usability, accessibility, and potential impact of these apps.

Development of a tablet app designed to improve African Americans' screening colonoscopy rates.

Compared with other racial/ethnic groups, African Americans have the highest colorectal cancer (CRC) morbidity and mortality rates. It is critical to help improve African Americans' CRC prevention efforts in order to reduce the burden of CRC in this community. The aim of this study was to develop and field test a tablet app, called e-Motivate, designed to improve African Americans' screening colonoscopy rates. The e-Motivate app was field tested, using an iterative approach. The first version of the app, e-Motivate 1.0, was field tested on 20 African Americans over the age of 50. Participants engaged in a think aloud exercise and provided feedback regarding the app's usability and acceptability. The results of the first field test were used to modify the app and develop e-Motivate 2.0. The field test procedures were repeated on a new group of participants (N = 18). The results from the second field test were used to make final modifications to the app. Overall, participants responded positively to the app. Qualitative analyses showed that participants found the app to be easy to use and helpful. Furthermore, descriptive statistics revealed that participants found the app to be highly usable and acceptable, exceeding recommended benchmarks for usability and acceptability. Critiques of the app were used to modify and finalize the intervention. The results from the proposed study suggest that the e-Motivate app is highly feasible and acceptable. The next step in this line of research is to conduct a randomized clinical trial to formally test the efficacy of the e-Motivate app for improving screening colonoscopy rates among African Americans.
