Content and accuracy of vaccine information on pediatrician blogs

Does Exposure to Pediatrician or Parent Blog Content Influence Infant Safe Sleep Practices?

OBJECTIVE

To examine whether exposure to safe sleep recommendations using a blog format changed infant sleep practices.

METHODS

We conducted a pilot randomized controlled trial via Qualtrics, a web-based platform, with a national sample of parents of children < 1 year old. Survey questions about infant sleep practices included: bed-sharing, location, position and objects present. Safe sleep was defined as not bed-sharing, in a crib, bassinet or playard, back positioning, and no other objects present except pacifiers. Participants were randomized to read one of the following: (1) pediatrician blog post, (2) parent blog post, or (3) no blog post. The blog posts contained the same content about infant sleep but varied by identified authorship. All participants received links to online content about safe sleep. Participants received a follow-up survey 2-4 weeks later with the same questions about infant sleep practices. We compared responses in pre- and post-surveys by type of blog post exposure using multivariable logistic regression models.

RESULTS

The average infant age (n = 1500) was 6.6 months (Standard Deviation 3.3). Most participants (74%) were female; 77% were married; 65% identified as white Non-Hispanic, 12% were black and 17% were Hispanic. 47% (n = 711) completed both surveys. We identified no differences in the odds of any of the four safe sleep practices after exposure to safe sleep recommendations in blog post format.

CONCLUSION

Although in-person advice has been associated with improved safe sleep practices, we did not identify changes in infant sleep practices after exposure to safe sleep advice using blog posts.

Social media in health communication: A literature review of information quality

BACKGROUND

Social media is used in health communication by individuals, health professionals, disease centres and other health regulatory bodies. However, varying degrees of information quality are churned out daily on social media. This review is concerned with the quality of Social Media Health Information (SMHI).

OBJECTIVE

The review sought to understand how SMHI quality issues have been framed and addressed in the literature. Health topics, users and social media platforms that have raised health information quality concerns are reviewed. The review also looked at the suitability of existing criteria and instruments used in evaluating SMHI and identified gaps for future research.

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the forward chaining strategy were used in the document search. Data were sourced according to inclusion criteria from five academic databases, namely Scopus, Web of Science, Cochrane Library, PubMed and MEDLINE.

RESULTS

A total of 93 articles published between 2000 and 2019 were used in the review. The review revealed a worrying trend of health content and communication on social media, especially of cancer, dental care and diabetes information on YouTube. The review further discovered that the Journal of the American Medical Association, the DISCERN and the Health on the Net Foundation, which were designed before the advent of social media, continue to be used as quality evaluation instruments for SMHI, even though technical and user characteristics of social media differ from traditional portals such as websites.

CONCLUSION

The study synthesises varied opinions on SMHI quality in the literature and recommends that future research proposes quality evaluation criteria and instruments specifically for SMHI.

Does the Narrative Voice Influence Parental Perceptions of Pediatrician Blogs?

OBJECTIVE

To determine parental perceptions of pediatrician blog posts by narrative voice.

METHODS

Three blog posts each on 2 topics (vaccines and sleep) were written by an established physician blogger and varied by narrative voice (personal, third person objective and mixed). Topics were chosen to be applicable to all parents. Blog posts were evaluated by a communications expert, 2 research investigators, and 3 parents to confirm differences in narrative voice. We sampled parents of children 0 to 18 years old in 4 primary and subspecialty care clinics, and 1 inpatient medical unit. Participants were randomized to read 2 blog posts (1 per topic) that varied by narrative voice. Participants rated their perceptions of the accuracy, reliability, and appeal for each blog posts on a 5-point Likert Scale. The Kruskal-Wallis test was used to compare the distribution of parental rankings for accuracy, reliability, and appeal.

RESULTS

The average participant age (n = 258) was 39.8 (SD 9.7), 83% were female. Blog posts written in the third person objective voice were rated as more accurate and reliable than those in the personal or mixed voice. There was effect modification by topic, with parents rating the sleep blog posts as more accurate than the vaccine blog posts. There was no difference in the appeal of information by narrative voice or topic of blog post.

CONCLUSIONS

The narrative voice used to convey information on pediatrician blog posts can influence reader perception of accuracy and reliability. Physician bloggers can enhance parental trust of their content using study findings.

Vaccine Hesitancy as a Challenge or Vaccine Confidence as an Opportunity for Childhood Immunisation in India

Vaccines have contributed substantially to decreasing the morbidity and mortality rates of many infectious diseases worldwide. Despite this achievement, an increasing number of parents have adopted hesitant behaviours towards vaccines, delaying or even refusing their administration to children. This has implications not only on individuals but also society in the form of outbreaks for e.g. measles, chicken pox, hepatitis A, etc. A review of the literature was conducted to identify the determinants of vaccine hesitancy (VH) as well as vaccine confidence and link them to challenges and opportunities associated with vaccination in India, safety concerns, doubts about the need for vaccines against uncommon diseases and suspicions towards new vaccines were identified as major vaccine-specific factors of VH. Lack of awareness and limited access to vaccination sites were often reported by hesitant parents. Lastly, socio-economic level, educational level and cultural specificities were contextual factors of VH in India. Controversies and rumours around some vaccines (e.g., human papillomavirus) have profoundly impacted the perception of the risks and benefits of vaccination. Challenges posed by traditions and cultural behaviours, geographical specificities, socio-demographic disparities, the healthcare system and vaccine-specific features are highlighted, and opportunities to improve confidence are identified. To overcome VH and promote vaccination, emphasis should be on improving communication, educating the new generation and creating awareness among the society. Tailoring immunisation programmes as per the needs of specific geographical areas or communities is also important to improve vaccine confidence. Fig. 1 Plain language summary.

What Matters to Parents Regarding Immunization of Their Children: Systematic Analysis of Expert Advice to Parents in an Internet Forum

BACKGROUND

World Health Organization announced vaccine hesitancy among the top 10 threats to global health in 2019. While the number of persons looking for information on health topics on the internet is increasing, information regarding immunization on the internet is often inaccurate and misleading. We aimed to determine the kind of information parents seek on the internet for decision-making regarding immunizations for their children.

METHODS

We investigated threads of an internet vaccine forum, where parents can get personalized advice from a vaccine expert, with regard to the types of vaccines and content of the questions. One thousand six hundred twenty consultations (4896 questions) between September 2001 and December 2018 were examined. Of these, 1386, including 4000 questions, were related to immunizations of the user's child. Date of consultation, user gender and country of residence, age of the child; kind of vaccine(s), and topic of the question according to the following categories were analyzed: Vaccination schedule, safety, effectiveness, necessity, vaccine application, serology, exchangeability of different vaccine types and brands, maternally acquired immunity, reimbursement, and vaccine product related.

RESULTS

Most questions concerned infants (47.7%) and regarded measles-component (28.9%) and diphtheria-tetanus-pertussis combination vaccines (25.3%). Parents were mainly interested in vaccination schedule (33.8%), safety (26.6%), and effectiveness (17.8%) of vaccines. Over time, safety-related questions decreased, and effectiveness related questions increased. Disease outbreaks or newly introduced vaccines and vaccinations temporarily raised interest. From 2011 onwards, most questions regarded measles-component vaccines.

CONCLUSIONS

Our findings will assist health care professionals and policy makers in preparing targeted information campaigns to address questions and counteract vaccine hesitancy.

The use of technology to promote vaccination: A social ecological model based framework

Vaccinations are an important and effective cornerstone of preventive medical care. Growing technologic capabilities and use by both patients and providers present critical opportunities to leverage these tools to improve vaccination rates and public health. We propose the Social Ecological Model as a useful theoretical framework to identify areas in which technology has been or may be leveraged to target undervaccination across the individual, interpersonal, organizational, community, and society levels and the ways in which these levels interact.
