Abstract
Background
Online postal self-sampling (OPSS) for HIV/STI improves testing access and coverage. We assessed the acceptability, usability, and user experiences of the “Test2Know” (T2K) OPSS platform in Flanders, Belgium, to inform further implementation.
Methods
Eligible users completed a risk-assessment to determine infections (HIV, syphilis, chlamydia, gonorrhoea, hepatitis C) and anatomical sites for testing. Self-collected samples were mailed to the laboratory, and results were communicated via the platform. Users completed surveys on acceptability, usability and overall user experience.
Results
Of 131 individuals who received a kit; 98 (74.8%) returned samples. 62.2% were male, 27.6% were men who had exclusively sex with men, and the median age was 29 years. Nearly 43% had never been tested for HIV or did not recall previous testing. 9 (9.2%) tested positive for an STI, all men; 7/9 reported sex exclusively with men, and 2/9 had never tested for HIV. No HIV or HCV infections were detected. Usability and acceptability were 89.2% and 83.3% respectively, nearly 90% would reuse and recommend the platform. However, 45.4% preferred a mixed testing approach due to blood collection challenges.
Conclusions
OPSS is highly acceptable and reaches individuals at risk for STI. Further research should explore sustainable integration into Belgian healthcare.
