Previous studies on Internet sites indicate that some Web-based material on sport-related orthopedic disorders is biased, misleading, and conveying inaccurate health messages. Our hypothesis was that Web-based content on platelet-rich plasma (PRP) therapy from commercial sites is frequently imbalanced, biased, and incorrect.
In this descriptive epidemiological study, an Internet search was performed using the search engine Google using keywords "platelet-rich plasma" and "platelet-rich plasma therapy." Exclusion criteria were medical or scientific journal, encyclopedia, or medical reference articles.
Publicly available Internet resources were examined.
Web-based resources identified through an Internet search engine.
Using content analysis, we assessed each reference for factual accuracy, themes depicted, opinions, and recommendations.
Our search yielded a total of 44 articles, of which 26 unique articles met the inclusion criteria. Twenty of 26 articles (77%) made inappropriate statements regarding evidence, treatment, efficacy, or safety of PRP injections. Twenty-three articles (88%) were medically imbalanced, discussing only perspectives of physicians favoring the treatment. Only 8 articles (31%) discussed alternative treatment options. Twenty-two articles (85%) used individual dramatized patient experiences to demonstrate the effectiveness of PRP. Nineteen articles (73%) made unsubstantiated promises regarding health outcomes of PRP injections. Many accessed Internet sites were from medical practices or institutions where PRP therapy was used.
Our data indicate that some Web-based references to PRP therapy are biased and inaccurate. We are concerned that some readers will misinterpret such easily available, but poorly controlled, information, potentially leading to use of unproven therapies.
之前关于互联网网站的研究表明，一些与运动相关的骨科疾病的基于网络的材料存在偏见、误导和传递不准确的健康信息。我们的假设是，来自商业网站的关于富含血小板的血浆（PRP）治疗的基于网络的内容经常是不平衡的、有偏见的和不正确的。
在这项描述性流行病学研究中，使用搜索引擎 Google 进行了互联网搜索，使用的关键词是“富含血小板的血浆”和“富含血小板的血浆治疗”。排除标准是医学或科学杂志、百科全书或医学参考文章。
检查了公开可用的互联网资源。
通过互联网搜索引擎确定的基于网络的资源。
使用内容分析，我们评估了每个参考文献的事实准确性、描述的主题、观点和建议。
我们的搜索共产生了 44 篇文章，其中 26 篇独特的文章符合纳入标准。26 篇文章中的 20 篇（77%）对 PRP 注射的证据、治疗、疗效或安全性做出了不适当的陈述。23 篇文章（88%）在医学上不平衡，只讨论了赞成治疗的医生的观点。只有 8 篇文章（31%）讨论了替代治疗方案。22 篇文章（85%）使用个体戏剧化的患者经验来证明 PRP 的有效性。19 篇文章（73%）对 PRP 注射的健康结果做出了没有根据的承诺。许多访问的互联网网站来自使用 PRP 治疗的医疗实践或机构。
我们的数据表明，一些关于 PRP 治疗的基于网络的参考文献存在偏见和不准确。我们担心一些读者会错误地解释这些容易获得但控制不佳的信息，从而可能导致使用未经证实的治疗方法。
