100 Million Views of Electronic Cigarette YouTube Videos and Counting: Quantification,Content Evaluation,and Engagement Levels of Videos

BackgroundThe video-sharing website, YouTube, has become an important avenue for product marketing, including tobacco products. It may also serve as an important medium for promoting electronic cigarettes, which have rapidly increased in popularity and are heavily marketed online. While a few studies have examined a limited subset of tobacco-related videos on YouTube, none has explored e-cigarette videos’ overall presence on the platform.ObjectiveTo quantify e-cigarette-related videos on YouTube, assess their content, and characterize levels of engagement with those videos. Understanding promotion and discussion of e-cigarettes on YouTube may help clarify the platform’s impact on consumer attitudes and behaviors and inform regulations.MethodsUsing an automated crawling procedure and keyword rules, e-cigarette-related videos posted on YouTube and their associated metadata were collected between July 1, 2012, and June 30, 2013. Metadata were analyzed to describe posting and viewing time trends, number of views, comments, and ratings. Metadata were content coded for mentions of health, safety, smoking cessation, promotional offers, Web addresses, product types, top-selling brands, or names of celebrity endorsers.ResultsAs of June 30, 2013, approximately 28,000 videos related to e-cigarettes were captured. Videos were posted by approximately 10,000 unique YouTube accounts, viewed more than 100 million times, rated over 380,000 times, and commented on more than 280,000 times. More than 2200 new videos were being uploaded every month by June 2013. The top 1% of most-viewed videos accounted for 44% of total views. Text fields for the majority of videos mentioned websites (70.11%); many referenced health (13.63%), safety (10.12%), smoking cessation (9.22%), or top e-cigarette brands (33.39%). The number of e-cigarette-related YouTube videos was projected to exceed 65,000 by the end of 2014, with approximately 190 million views.ConclusionsYouTube is a major information-sharing platform for electronic cigarettes. YouTube appears to be used unevenly for promotional purposes by e-cigarette brands, and our analyses indicated a high level of user engagement with a small subset of content. There is evidence that YouTube videos promote e-cigarettes as cigarette smoking cessation tools. Presence and reach of e-cigarette videos on YouTube warrants attention from public health professionals and policymakers.

Improving Hepatitis Vaccination Series Completion in Patients Awaiting Liver Transplantation

The aim of this quality improvement project was to improve hepatitis A and B vaccination rates by 20% in patients listed for liver transplant by improving vaccine tracking, ordering/scheduling practices, out-of-network vaccinations, and flagging electronic health records. We audited 101 records; 44 patients were vaccine-deficient. Combined vaccine completion rates improved 94.6% (44.7%-87.0%) after implementing the educational and health record interventions. We believe the results of this study have implications for improving survival and decreasing complication rates for patients with chronic liver disease.

The Accuracy and Trends of Smoking History Documentation in Electronic Medical Records in a Large Managed Care Organization

The accuracy of smoking history documentation in the electronic medical records was examined at a large managed care organization among 36,494 male members who self-reported smoking history in mailed surveys. The sensitivity of electronic smoking history documentation for ever-smoking status was 0.19 in years 2003–2005 (using ICD-9/CPT code only), 0.80 in 2006–2008 and 0.84 in 2009–2010 (combination of ICD-9/CPT codes and risk factor module used after 2006). The positive predictive value was 0.96, 0.90, and 0.95 in these periods, respectively. Among self-reported ever-smokers, increased healthcare utilization and smoking intensity/duration were associated with higher likelihood of having electronic smoking history documentation, while Asian race and Spanish language preference were associated with lower likelihood. These data suggest that enhanced efforts may be needed to screen for and document smoking among racial/ethnic minorities.
