Takeaway

  • This study of Internet queries found a spike in queries about respiratory symptoms among search engine users who had undergone colonoscopy 7-10 days prior.

Why this matters

  • Little is known about nonsevere adverse effect rates after colonoscopy.
  • Colonoscopy with sedation is common in multiple countries, including the UK, Italy, and Singapore.
  • Aspiration pneumonia might be an underreported complication of the procedure.

Key results

  • Of queries about colonoscopy, 28% were made after the date of the test.
  • Of those, the most common query (2.6%) addressed respiratory symptoms (cough, 1.21%; pneumonia, 0.58%).
  • Those occurred most commonly about a week after colonoscopy.

Study design

  • Study of search engine queries.
  • Authors tallied 641,223 users’ queries on “colonoscopy,” then isolated subgroup in whom test date could be estimated (n=7013).
  • They then checked whether those users subsequently queried about medical symptoms for 5 days before to 30 days after the date of colonoscopy. 
  • Funding: None.

Limitations

  • Potential for selection bias.
