An assessment of the quality and content of information on diverticulitis on the internet

The COVID-19 and chloroquine infodemic: Cross-sectional observational study of content analysis on YouTube

The objective of this study is to evaluate the association between quality and features related to internet users of the most viewed YouTube videos about COVID-19 and chloroquine, during the first wave of the pandemic. We conducted a cross-sectional observational study focusing on the most viewed YouTube videos on COVID-19 and chloroquine treatment, in French and English. The primary outcome was the association between video quality as assessed by DISCERN and modified JAMA scores, and video features related to internet users as assessed by number of viewership and likes. By June 2020, 168 videos accumulating more than 57 million views and nearly 2 million reactions from Internet users, were included. Most of the videos did not support or oppose the treatment and came from news channels (N = 100; 60%). Videos taking sides were mostly pro-chloroquine (N = 69; 89%). The number of non-factual videos analyzed was very low (N = 3; 2%). The quality of the videos was average (mean DISCERN score = 2.4 (DS 1.0) and mean modified JAMA score = 2.6 (DS 0.6)) and declined over time. The best quality videos were those published by health care professionals or those from educational channels. Most experts interviewed were men (N = 136; 81%). More than 1 in 5 videos featured a political figure (N = 35; 21%), and these were mostly pro-chloroquine with lower DISCERN or modified JAMA scores (p<0.001). We found an association between the number of likes and the quality of the videos evaluated by the DISCERN score (rho = 0.29; p<0.001) and the modified JAMA score (rho = 0.30; p<0.001). The association observed between the quality of the videos and the number of likes suggests a better health literacy and critical thinking of lay internet users. Although YouTube has become a major player in the dissemination of medical information, more involvement of health professionals and governmental organizations is needed.

The quality and content of hyperthermic intraperitoneal chemotherapy information available to patients: An evaluation of North American hyperthermic intraperitoneal chemotherapy websites

BACKGROUND

Patients commonly use the internet to obtain medical information. Patients in our outpatient setting frequently have incomplete or even incorrect information about hyperthermic intraperitoneal chemotherapy that they have found on the internet. We aimed to assess the quality and content of Web-based information on hyperthermic intraperitoneal chemotherapy using validated and novel scoring systems.

METHODS

The keywords "HIPEC" and "hyperthermic intraperitoneal chemotherapy" were entered into the most commonly used internet search engines (Google, Bing, and Yahoo). The first 10 websites from each search were analyzed. Website quality was assessed using the validated Journal of the American Medical Association benchmark criteria and DISCERN scoring systems. We created a novel hyperthermic intraperitoneal chemotherapy-specific score with surgeon experts in the field.

RESULTS

Eighteen unique websites were identified. The majority (78%) were from academic institutions. The mean total DISCERN score for all websites was 41.8 ± 8.4 (maximum possible points = 75). The mean Journal of the American Medical Association and hyperthermic intraperitoneal chemotherapy-specific scores were 1.72 ± 1.13 (maximum possible score = 4) and 11.5 ± 4.5 (maximum possible score = 31), respectively. The lowest Journal of the American Medical Association scores were in the category of authorship. In total, 78% of websites omitted author details; 83% and 78% included the temperature and duration of hyperthermic intraperitoneal chemotherapy, respectively. Only 39% of websites mentioned complications of hyperthermic intraperitoneal chemotherapy.

CONCLUSION

Web-based information on hyperthermic intraperitoneal chemotherapy is of variable content and quality. None of the websites achieved maximum scores using any of the scoring tools. Less than half of the websites provided any information on possible complications of the procedure. These findings should be highlighted to patients using the internet to obtain information about hyperthermic intraperitoneal chemotherapy.

Quality of information regarding abnormal uterine bleeding available online

INTRODUCTION

The Internet and electronic devices with Internet access allow for a greater fluidity of information and speed of communication, especially in the field of health. Abnormal uterine bleeding (AUB) affects approximately 3-30% of women and can negatively impact their health and quality of life. Information regarding AUB that is available on the Internet may not be clear or accurate, rendering it difficult to understand and likely to result in delayed medical evaluation, which subsequently leads to worsening of the AUB.

OBJECTIVE

To evaluate the quality of the information regarding AUB currently available on the Internet, including information regarding treatments.

METHODS

The Google Trends website was searched for the most widely used English terms related to AUB. The identified descriptors were searched individually on the Google, Yahoo!, and Bing search engines. The first 10 results of each search were pre-selected and evaluated for inclusion in this study. Selected websites were categorically divided into two groups (news/magazine and academic) and individually analyzed by three experts using the DISCERN quality criteria (reliability, general quality, and quality of information) and the presence or absence of the Health on the Net Foundation Code of Conduct (HONcode®) seal.

RESULTS

Of the 168 websites included in this study, 60.1% were allocated to the news/magazine group and 39.9% were allocated to the academic group. Over half of the websites (54.2%) did not have the HONcode® quality seal. Websites in the academic group were more likely to include accurate information regarding AUB with greater reliability than websites in the news/magazine group. There were no statistical differences regarding the general quality of the websites. Most websites were rated as either moderate quality (70.8%) or low quality (28.6%). The HONcode® criterion was found to be a confounding factor of the analyses, as the grouping and quality results of websites without this seal were significantly associated. In addition, websites in the news/magazines group were 6.7 times more likely to provide low quality information than websites in the academic group (odds ratio: 6.7; 95% confidence interval: 2.1-21.4).

CONCLUSION

The information regarding AUB that is available on the Internet is of low to moderate quality. Academic websites present more reliable information of greater quality. The presence of the HONcode® seal is considered important to determine the quality of the content of a website, especially for news/magazine websites, and may help Internet users identify websites that contain more reliable information. Algorithms and applications that categorize the quality of information and the reliability of health content may be useful tools that can help patients clarify their symptoms for several conditions including AUB.

A Systematic Review of Online Patient Resources to Support Shared Decision Making for Laparoscopic Cholecystectomy

BACKGROUND

RCS Eng, the Royal College of Surgeons of England, has published much information with regard to the consenting process. A majority of patients seek health information through online resources as well as discussing with the care givers. Therefore, it is necessary that online material is both of high quality and reliable for patients. We aimed to evaluate the quality and standard of the online patient information on laparoscopic cholecystectomy to help in the consenting process.

METHODS

A search was carried out as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Sources were assessed using five validated scoring tools: Flesch-Kincaid Reading Ease Score (readability), DISCERN and IPDAS scores (quality of content) and HONcode and the Information Standard Certification (standards of accreditation).

RESULTS

The average readability of all websites was higher than recommended for patient literature. Less than half of the sources had received HONcode or Information Standard accreditation. On grading of quality and content, across validated scoring tools, no source achieved the minimum recommended level.

CONCLUSION

Online patient information related to laparoscopic cholecystectomy is of poor quality. We recommend a multidisciplinary approach to participate in publishing more readable online resources of a higher standard to help patients and clinicians in consent and shared decision making.

An evaluation of the quality and content of web-based stoma information

AIM

Although the internet is commonly the first port of call for medical information, it provides unregulated data of variable quality. We aimed to evaluate commonly accessed web-based information on intestinal stomas using validated and novel scoring systems.

METHOD

The keywords 'stoma', 'colostomy', 'ileostomy' and 'bowel bag' were entered into the most commonly used internet search engines (Google, Bing and Yahoo). The first ten websites from each search were analysed using the validated Journal of the American Medical Association (JAMA) benchmark criteria and DISCERN scoring systems. A novel stoma-specific score was devised and applied.

RESULTS

Forty-three unique websites were identified. The majority (49%) were from nonprofit or governmental agencies and 9% were from commercial entities. The mean total DISCERN score for all websites was 42.4 ± 10.2 (maximum possible score = 75). The mean JAMA and stoma-specific scores were 2.1 ± 1.0 (maximum possible score = 4) and 12.9 ± 6.1 (maximum possible score = 27). The lowest JAMA scores were in the category of attribution, with 70% of websites lacking references for the information provided. A total of 88% displayed disclosure/paid advertiser information. Surgery was described in 67%. An image or diagram was provided in 58% and in 72% a stoma therapist/nurse was mentioned. Information on when to seek medical help was provided in 51%.

CONCLUSION

Web-based information on stomas is of variable content and quality. Authorship and information sources are often unclear. Only half provided information on when to seek medical help for complications including high output and dehydration. These findings should be highlighted to patients who utilize the internet to obtain information on stomas.
