YouTube videos with information about implantable cardioverter defibrillators were often found to be of poor quality, containing incomplete information about the device and potential outcomes, one speaker reported.

An analysis assessing the quality of INN information in YouTube videos was presented at the American College of Cardiology Quality Summit.

“It is so important that patients have access to high quality information because it can be difficult to interact with healthcare professionals,” Thomas J. Lee, MS, a medical student at Sidney Kimmel Medical College in Philadelphia, said in a press release. “Often a patient will have to wait weeks or even months before they can have their questions answered with confidence,” Lee said. “The problem is that on YouTube, a lot of the informative videos appear to be high quality because of a hospital environment or a doctor, but in reality the video doesn’t paint the full picture of a placement of DIA.”

To better assess the quality of consumer health videos related to ICDs, the researchers searched YouTube for videos using the term “implantable cardioverter defibrillator” and scored them using the modified DISCERN criteria – a tool to assess the quality of consumer health information – and an electrophysiologist. new content score.

Using a scale of 0 to 25, with higher scores indicating higher quality consumer health information, the researchers used the following qualitative score cutoffs: very poor (

The novel content score assessed by an electrophysiologist was similar but ranged from 0 to 10.

Fifty YouTube videos about ICDs were included in the analysis, of which 29 were from academic medical centers, 13 from medical device companies, and eight from independent uploaders.

Lee and colleagues found that the overall quality of consumer health information in YouTube videos was poor, with an average modified DISCERN score of 12.58 and an average novel content score of 3.68.

Videos created by medical device companies received lower modified DISCERN scores than academic medical centers (mean difference, 1.68) and independent uploaders (mean difference, 1.54; ANOVA P = .011), depending on the presentation.

Lee and colleagues found that 88% of videos included in the analysis did not mention inappropriate ICD shock as a possible event.

Additionally, researchers found a positive association between video length and modified DISCERN score (r = 0.3; P = 0.034) and novel content score (r = 0.45; P = 0.001 ); however, they observed no correlation between video popularity metrics and video quality.

“Patients likely seek information about their medical conditions and procedures online primarily due to their convenience and familiarity with the Internet, especially YouTube,” Lee said in the statement. “Most people only have a short time to speak to a clinician about an ICD placement, so it would make sense for them to search the internet for more information about it. Although we cannot prevent our patients to obtain information online, nor would we want to restrict their access to information about their condition, it is important that the medical community strives to ensure better quality information that gives a complete picture of a treatment or procedure is available.
