위식도역류질환에 대한 국내 인터넷 의료 정보 평가 = An Evaluation of Web-based Informations about Gastroesophageal Reflux Diseases in Korea

다국어 초록 (Multilingual Abstract)

Background/Aims: Internet has become an important source of medical information not only for medical personnels but also for patients. The aim of this study was to evaluate the quality of internet based medical information about ``gastroesophageal reflux`` or ``reflux esophagitis`` in Korea. Methods: The first 15 internet sites using the key words ``gastroesophageal reflux`` or ``reflux esophagitis`` were retrieved from the 7 most frequently used internet search engines. The quality of information from a total of 108 websites was evaluated using a checklist. Results: Among total 108 sites related to ``gastroesophageal reflux`` or ``reflux esophagitis``, fifty-six sites (51.8%) were made by hospitals or clinics and 94 sites (87.0%) were made for patients. Of the 108 sites, eleven web sites (10.1%) had more than three JAMA benchmarks (authorship, references, currency, and disclosure). Higher quality sites (at least three JAMA benchmarks) were less likely to contain inaccurate information than lower quality sites (fewer than three JAMA benchmarks)-3/11 (27.2%) vs. 60/97 (61.9%) (p＜0.01). Despite the fact that articles in the literature emphasized an insufficient evidence to support an association between the lifestyle, dietary behaviors, and GERD, such guidelines continue to be recommended as first-line therapy in most websites. Conclusions: Informations about gastroesophageal reflux disease were incomplete in the majority of medical web sites. These would bring about confusion to patients seeking for an information about GERD through the internet. There is a need for better sources in evidence based informations about gastroesophaeal reflux diseases on the web. (Korean J Gastroenterol 2007;49:231-237)
