ASSESSMENT OF INFORMATIONAL QUALITY AND CREDIBILITY OF YOUTUBE® CONTENT ON OSTEOSARCOMA

Öz

Objective: YouTube is increasingly used as a source of health information; however, the accuracy and reliability of its medical content remain questionable. This study aimed to assess the quality and reliability of YouTube videos related to osteosarcoma. Methods: In March 2025, the first 50 YouTube videos for the search terms “osteosarcoma” and “osteosarcoma surgery” were screened. After removing duplicates and applying exclusion criteria, 61 videos were included. Two orthopedic surgeons independently evaluated the videos for uploader type, views, duration, likes, and dislikes. Popularity was measured using the Video Power Index (VPI) and view ratio. Scientific quality was assessed using DISCERN and JAMA scores. Statistical analyses included the Shapiro-Wilk, Spearman correlation, and Kruskal-Wallis tests (p < 0.05). Results: Only 8.1% of videos were rated as good or excellent based on DISCERN scores, while 70.4% were categorized as poor or very poor. Physician-uploaded videos (52.5%) had significantly higher DISCERN and JAMA scores (p < 0.01), yet lower popularity metrics compared to patient and commercial uploads (p < 0.05). A strong positive correlation was found between DISCERN and JAMA scores (rho = 0.605, p < 0.001), but no significant relationship existed between content quality and popularity indicators. Conclusion: Although videos uploaded by physicians demonstrated higher quality, overall informational standards were low. The preference for popular but less reliable content highlights the need for accurate, accessible, and engaging medical videos on online platforms to support patient education and informed decision-making.

OSTEOSARKOMLA İLGİLİ YOUTUBE® İÇERİKLERİNİN BİLGİLENDİRİCİ KALİTESİ VE GÜVENİLİRLİĞİNİN DEĞERLENDİRİLMESİ

Öz

Amaç: YouTube giderek artan bir şekilde sağlık bilgisi kaynağı olarak kullanılmaktadır; ancak tıbbi içeriğinin doğruluğu ve güvenilirliği hala sorgulanmaktadır. Bu çalışma, osteosarkomla ilgili YouTube videolarının kalitesini ve güvenilirliğini değerlendirmeyi amaçlamaktadır. Yöntem: Mart 2025'te, "osteosarkom" ve "osteosarkom cerrahisi" arama terimleri için ilk 50 YouTube videosu taranmıştır. Tekrarlanan videolar çıkarıldıktan ve dışlama kriterleri uygulandıktan sonra 61 video çalışmaya dahil edilmiştir. İki ortopedi cerrahı, videoları yükleyici türü, görüntüleme sayısı, süre, beğeni ve beğenmeme açısından bağımsız olarak değerlendirmiştir. Popülerlik, Video Güç İndeksi (VPI) ve görüntüleme oranı kullanılarak ölçülmüştür. Bilimsel kalite, DISCERN ve JAMA puanları kullanılarak değerlendirilmiştir. İstatistiksel analizler Shapiro-Wilk, Spearman korelasyon ve Kruskal-Wallis testlerini içermektedir (p < 0,05). Bulgu: Videoların yalnızca %8,1'i DISCERN puanlarına göre iyi veya mükemmel olarak derecelendirilirken, %70,4'ü kötü veya çok kötü olarak kategorize edildi. Hekimler tarafından yüklenen videoların (%52,5) DISCERN ve JAMA puanları önemli ölçüde daha yüksekti (p < 0,01), ancak hasta ve ticari yüklemelere kıyasla daha düşük popülerlik ölçütleri vardı (p < 0,05). DISCERN ve JAMA puanları arasında güçlü bir pozitif korelasyon bulundu (rho = 0,605, p < 0,001), ancak içerik kalitesi ve popülerlik göstergeleri arasında anlamlı bir ilişki yoktu. Sonuç: Hekimler tarafından yüklenen videolar daha yüksek kalite gösterse de, genel bilgi standartları düşüktü. Popüler ancak daha az güvenilir içeriklere olan tercih, hasta eğitimini ve bilinçli karar vermeyi desteklemek için çevrimiçi platformlarda doğru, erişilebilir ve ilgi çekici tıbbi videolara olan ihtiyacı vurgulamaktadır.
