title: Systematic evaluation of obstructive sleep apnea websites on the internet.
abstract: OBJECTIVE
  To determine the quality and comprehensiveness of the websites on the Internet with information directed toward patients with obstructive sleep apnea (OSA).
  
  
  METHODS
  Systematic evaluation of websites on the Internet with information on OSA.
  
  
  METHODS
  World Wide Web.
  
  
  METHODS
  The search engine Google was queried with the term "obstructive sleep apnea." The first 50 results were evaluated. Only websites written in English and containing original information were reviewed.
  
  
  METHODS
  A data quality score (DQS) was generated by evaluating each website for the presence of 67 points of information relating to OSA. Each website was also evaluated using a Global Quality Score (GQS), the DISCERN instrument, the Flesch-Kincaid reading grade level, date of the last update, and sources of funding.
  
  
  RESULTS
  Thirty-four websites met the inclusion criteria. The average DQS was 36 points (range 17-57). The average GQS was 2.9 (range 1-5). The average DISCERN score was 3.3 (range 1.9-4.7). The average reading grade level was 11.0 (range 5.0-15.8). Twenty-six websites (76%) provided authorship information. Twenty-five websites (74%) displayed a date of the last update. Of these, 12 websites were not updated within the past 2 years. Twenty websites (59%) provided a source of funding.
  
  
  CONCLUSIONS
  There is a heterogeneous mixture of websites with varying quality on the Internet with information regarding OSA. Health care providers should be cognizant of the variety of information available for patients and be prepared to direct patients toward the high-quality information sources.
