PMID 41453252WHAT IT FOUND
DiTA was rated above average for usability.
Physical therapy clinicians and researchers liked its diagnostic test accuracy content, but many struggled with search fields and syntax, so expect to troubleshoot searches.
Key findings
01The group's mean usability score was 70.9 on a 0 to 100 scale, above the benchmark mean of 67.
02Content was the most commented category (161 of 329 comments) and had more positive than negative comments (64 positive to 39 negative).
03Functionality had more negative than positive comments (20 negative to 16 positive) and was the most common source of misinterpretations (33 of 74; 45%).

What it does not show
Only 25 participants took part, and all were recruited in Australia, although DiTA had users in many countries and Brazil had the largest usage. Participants came from the authors' professional contacts, so they may have been more favourable or less typical than other physical therapists. The study did not report how often searches succeeded, because the authors judged that success mixed together question wording, database content, and site usability. Interviewer prompts may have influenced the search tasks, and the study could not record how often this happened. The authors checked coding agreement on three interviews, then one author coded the remaining 22 interviews. The study measured user experience and website use, not diagnostic accuracy or clinical outcomes.
Declared interests
The authors declared no competing interests.
The easy way to misread this
Do not read the above-average usability score as evidence that DiTA improves diagnosis or patient care. The study measured website use by physical therapy clinicians and researchers, not diagnostic test accuracy or clinical outcomes.
