- Comparable Diagnostic Accuracy: The smartphone-based fecal immunochemical test (FIT) achieved performance similar to the standard laboratory FIT, with sensitivities of 28% versus 34% and identical specificity at 92%.
- Enhanced Accessibility and Convenience: The app-enabled FIT enables patients to collect and analyze stool samples at home using a smartphone, improving convenience and potentially increasing participation in colorectal cancer screening.
- High Patient Satisfaction: Among users, 92% found the app instructions clear, 94% said stool handling was manageable, 89% felt the test duration was appropriate, and 78% appreciated immediate result display within the app.
- Moderate Uptake and Valid Results: Of 654 participants, 55% used the smartphone-based FIT, and 76% of those achieved valid results. Participation was higher among men and individuals under age 60.
- Positive Perception as a Screening Alternative: Nearly 89% of participants viewed the smartphone-based FIT as a useful and acceptable alternative to standard lab tests.
- Potential to Boost Screening Participation: Smartphone-based FITs may help close screening gaps and encourage greater colorectal cancer screening participation, particularly among younger, tech-savvy populations.
