NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Quality of Urolithiasis Information on Wikipedia and Baidu Baike: Cross-Language Comparative Study Using Nurse and Patient Ratings
ABSTRACT
Background:
Online encyclopedic platforms are a common source of health information, but cross-language evaluations of urolithiasis content rated by both clinically informed and lay users remain limited.
Objective:
This study compared the quality of urolithiasis information on Wikipedia and Baidu Baike using ratings from urology nurses and patients.
Methods:
We conducted a cross-sectional comparison of 30 urolithiasis webpages (15 Wikipedia and 15 Baidu Baike). Pages were identified using clinically relevant English and Chinese search terms and were matched by exact topic or the nearest clinically equivalent concept. Two urology nurses and 2 patients independently rated each page using DISCERN and QUEST. For the main analysis, the 2 ratings within each evaluator group were averaged for each webpage. Primary outcomes were DISCERN and QUEST total scores. Platform differences were tested using the Mann-Whitney U test, interrater reliability was assessed with ICC(2,k), and mixed-effects models were used as sensitivity analyses.
Results:
Interrater agreement was good to excellent. Wikipedia scored higher than Baidu Baike on DISCERN total in nurse ratings (median 59.50 vs 50.50; P=.002) and patient ratings (61.50 vs 56.00; P=.020). Wikipedia also scored higher on QUEST total in nurses (18.50 vs 15.50; P=.038) and patients (19.00 vs 17.00; P=.016). After false discovery rate adjustment, only DISCERN reliability remained higher for Wikipedia in both evaluator groups, whereas no individual QUEST domain remained significant. Mixed-effects analyses were consistent with the primary findings.
Conclusions:
In this sampled cross-language comparison, Wikipedia received higher overall DISCERN and QUEST scores than Baidu Baike in both nurse and patient ratings. The clearest domain-level difference was in DISCERN reliability. Other domain-specific differences, especially within QUEST, were less consistent after adjustment for multiple testing.
