OBJECTIVE: Assessing the agreement of treatment effect estimates from
meta-analyses based on abbreviated or comprehensive literature searches.
STUDY DESIGN AND SETTING: Meta-epidemiological study. We abbreviated 47
comprehensive Cochrane review searches and searched MEDLINE/Embase/CENTRAL
alone, in combination, with/without checking references (658 new searches).
We compared one meta-analysis from each review with recalculated ones based
on abbreviated searches.
RESULTS: The 47 original meta-analyses included 444 trials (median 6 per
review [IQR 3-11]) with 360045 participants (median 1371 per review [IQR
685-8041]). Depending on the search approach, abbreviated searches led to
identical effect estimates in 34%-79% of meta-analyses, to different effect
estimates with the same direction and level of statistical significance in
15%-51%, and to opposite effects (or effects could not be estimated anymore)
in 6%-13%. The deviation of effect sizes was zero in 50% of the
meta-analyses and in 75% not larger than 1.07-fold. Effect estimates of
abbreviated searches were not consistently smaller or larger (median ratio
of odds ratio 1 [IQR 1-1.01]) but more imprecise (1.02-1.06-fold larger
standard errors).
CONCLUSION: Abbreviated literature searches often led to identical or very
similar effect estimates as comprehensive searches with slightly increased
confidence intervals. Relevant deviations may occur.

2. Developing an Online Consumer Health Course for Public Library Staff.
Kiscaden E, Newman B, Malachowski M, Martin C
The National Network of Libraries of Medicine, Greater Midwest Region (NNLM
GMR) received funding to support the evaluation and development of an
asynchronous consumer health information course. Requirements of this
project included: incorporating recommendations from NNLM instructors,
National Library of Medicine staff and public library staff; piloting the
revised course with a nationwide cohort; incorporating feedback from the
pilot; and delivering a second instance of the revised course. The revised
course meets existing requirements for public library certification and for
Level 1 certification of the Medical Library Association's Consumer Health
Information Specialization.

3. Finding useful cancer information may reduce cancer information
overload for Internet users.
Serçekuş P, Gencer H, Özkan S
BACKGROUND: An excessive overload of information causes an ineffective
management of information, stress and indefiniteness. Furthermore, this
situation can prevent persons from learning and making conscious decisions.
OBJECTIVE: This study aims to determine the cancer information overload
(CIO) and the factors related to it in adults who are Internet users.
METHODS: A cross-sectional study with 482 Internet users was conducted. The
data were collected by using an Introductory Information Form and the Cancer
Information Overload Scale.
RESULTS: It was found that the Internet was the most used information source
(62.2%). The CIO of those with a university level education was found to be
high (P = 0.012). It was found that the CIO of individuals who used the
Internet (P = 0.031) and newspapers/magazines (P = 0.004) as sources of
information was high compared with those who did not use these sources. It
was determined from the information obtained that those who found the
information to be beneficial and enough had a low CIO (P = 0.004, P = 0.00).
CONCLUSION: Health literacy around cancer information is challenging for
frequent Internet users. Health professionals, information specialists and
librarians should orient people to reliable sources.

4. Where are biomedical research plain-language summaries?
FitzGibbon H, King K, Piano C, Wilk C, Gaskarth M
Background and Aims: Plain-language summaries (PLS) are being heralded as a
tool to improve communication of scientific research to lay audiences and
time-poor or nonspecialist healthcare professionals. However, this relies on
PLS being intuitively located and accessible. This research investigated the
"discoverability" of PLS in biomedical journals.
Methods: The eLIFE list of journals/organizations that produce PLS was
consulted on July 12, 2018, for biomedical journals (based on title).
Internet research, primarily focusing on information provided by the journal
websites, explored PLS terminology (what do the journals call PLS),
requirements (what articles are PLS generated for, who writes/reviews them,
and at what stage), and location and sharing mechanisms (where/how the PLS
are made available, are they free to access, and are they visible on PubMed).
Results: The methodology identified 10 journals from distinct publishers,
plus eLIFE itself (N = 11). Impact factors ranged from 3.768 to 17.581. Nine
different terms were used to describe PLS. Most of the journals (8/11)
required PLS for at least all research articles. Authors were responsible
for writing PLS in 9/11 cases. Seven journals required PLS on article
submission; of the other four, one required PLS at revision and three on
acceptance. The location/sharing mechanism for PLS varied: within articles,
alongside articles (separate tab/link), and/or on separate platforms (eg,
social media, dedicated website). PLS were freely available when they were
published with articles; however, PLS were only included within conventional
abstracts on PubMed for 2/11 journals.
Conclusion: Across the few biomedical journals producing PLS, our research
suggests there is wide variation in terminology, location, sharing
mechanisms, and PubMed visibility. We advocate a more consistent approach to
ensure that PLS have appropriate prominence and can be easily found by their
intended audiences.

5. Evaluation of YouTube Video Content About Developmental Dysplasia of
the Hip.
Oztermeli A, Karahan N
Objective The purpose of this study is to investigate the quality and
reliability of YouTube videos regarding developmental dysplasia of the hip
(DDH). Background YouTube is one of the most popular websites used as a
source of information, but the variety in authorship and lack of a
peer-review process are problems. Methods The search string "developmental
dysplasia of the hip" was inputted to the YouTube search engine, and the
first 52 videos returned as a response were assessed. The Video Power Index
(VPI) (like ratio*view ratio/100) was used to assess the popularity of the
videos. Global Quality Score (GQS) and DDH scores (DDHS) were used to
evaluate the quality and educational quality of the videos, and the Journal
of the American Medical Association Score (JAMAS) was used to evaluate the
accuracy of the source of information. Results According to our research,
the mean duration time of the videos was 526 seconds (SD: 813), and the
average view count of the videos was 34,644. The mean time since upload was
1,907 days (SD: 1,137). On average, the videos received 10.9 comments, 210.3
likes, and 6.8 dislikes. The mean like ratio and VPI were 92.9 (SD: 19.57)
and 25.8 (SD: 53.43), respectively. The mean JAMAS, GQS, and DDHS of all
videos evaluated were 1.37 (SD: 0.7), 2.46 (SD: 1.09), and 4.63 (SD: 5.00),
respectively. The DDHS and GQS were positively correlated (p: 0.001; r:
65.8%). The GQS and the DDHS were higher in the academic group than in the
commercial group (p: 0.01 and p: 0.037, respectively). Conclusions The
videos regarding DDH on YouTube generally had poor quality. As a result, to
maintain an optimal parent-physician or patient-physician relationship, we
suggest that international health societies make their own educational
videos for parents, patients, and fellow physicians. Level of evidence Level

6. Can YouTube English videos be recommended as an accurate source for
learning about testicular self-examination?
Selvi I, Baydilli N, Akinsal EC
OBJECTIVE: To evaluate the content, reliability and quality of the most
viewed YouTube videos related to testicular self-examination (TSE).
METHODS: The terms "testicular self-examination", "testis examination" and
"testis exam" were used to search YouTube videos.Of 300 videos, a total of
123 videos were included.They were divided into two groups according to
accuracy: useful information (Group 1, n=78, 63.4%) and misleading
information (Group 2, n=45, 36.6%).A 5-point modified DISCERN tool was used
to assess the reliability,a 5-point Global Quality Score (GQS) was used to
evaluate the quality,and a 7-point scale was used to assess the
comprehensiveness of the videos.
RESULTS: DISCERN score (median 3, IQR:3-4 vs. median 1, IQR:0-2, p<0.001),
GQS (median 4, IQR:4-5 vs. median 1, IQR:1-2, p<0.001) and comprehensiveness
score (median 6, IQR:5-6 vs. median 1, IQR:0-2, p<0.001) were higher in
Group 1.This group also had higher numbers in terms of total views, views
per day and likes.It was seen that universities/professional
organizations/non-profit physician/physician groups (23.1%),stand-alone
health information websites (21.8%) and testicular cancer survivors (28.2%)
uploaded most of the videos in Group 1,whereas the majority in Group 2 were
individual users (68.9%).
CONCLUSION: We observed that YouTube videos are of high quality,reliability
and rich content in terms of all of the steps related to how TSE should be
done. However, since the YouTube search algorithm is not actually sufficient
enough, it is not easy and practical for a lay man to find a suitable video
by searching for "keyword" in the YouTube list.

7. Comparing quality and readability of online English language
information to patient use and perspectives for common rheumatologic
conditions.
Willen RD, Pipitone O, Daudfar S, Jones JD
Evaluate quality and readability of online information for common
rheumatologic diseases. Compare rheumatology patients' internet use and
preferences to an objective evaluation of internet quality and readability.
Five common rheumatologic diseases were searched on the web browser Google
using English language. The first twenty websites from each of the five
searches were evaluated for internet quality (e.g. content that is current,
balanced, has specific aims, and is appropriately cited) using the DISCERN
criteria and readability using the Flesch-Kincaid Grade Level (FKGL). The
results were contrasted with a survey sent to patients with rheumatic
disease. The survey measured patient likeliness to use and trust identified
websites. Internet quality was similar (good) for all five diseases searched
while readability was poor. There was an inverse relationship between
internet quality and readability. Internet quality significantly differed
across website sponsor, and readability significantly differed across
disease and website sponsor. Common medical website sponsors with the
highest combined quality and readability scores were Mayo Clinic and Web MD.
Eight hundred and fifty-eight patients were sent a survey, of which 147
(17%) completed. Patients indicated they were most likely to use and trust a
Mayo Clinic-sponsored website when compared to other common sponsored
websites from our evaluation, followed by the American College of
Rheumatology. Although we found good-quality information, all websites
evaluated had readability levels above the recommended sixth-grade reading
level. The website sponsor with the highest combined readability and quality
score was also the most used and trusted by patients. Patients would like
more information about credible and trusted websites from their medical
providers.

8. Public knowledge of low vision and blindness, and readability of
on-topic online information.
Lupón M, Cardona G, Armayones M
PURPOSE: To explore the laymen knowledge of low vision and blindness
concepts, and to assess the readability of some on-topic information
available online.
METHODS: A cross-sectional study was performed in March 2019. Knowledge was
evaluated by means of an ad hoc questionnaire-survey with two dichotomous
questions about concepts related to low vision and blindness, followed with
a list of 10 true-or-false statements. Readability of two on-topic online
texts of different complexity was evaluated asking participants to rate the
difficulty they experienced on a Likert scale and, objectively, by means of
the freeware INFLESZ Readability Scale for Spanish language. Data analysis
included descriptive statistics, t-tests, and ANOVA test (statistical
significance: p < 0.05).
RESULTS: Fifty-two percent of 103 participants declared never having heard
of low vision. Ninety-four percent participants were aware about the word
blindness, although most of them misinterpreted it. Neither academic level
nor age influenced knowledge (p > 0,05). Higher academic level was related
to better readability scores of the complex online text (p < 0.05).
CONCLUSION: Overall, the general public has a limited awareness of low
vision and a large misconception of blindness. Therefore, visual health
education actions should aim at fostering knowledge and literacy on the
issue. This strategy may encourage individuals to seek the advice of eye
care providers in order to prevent and treat visual impairment, with
relevant consequences in time, both in terms of quality of life and costs.

9. Core competencies for clinical informaticians: A systematic review.
Davies A, Mueller J, Moulton G
BACKGROUND: Building on initial work carried out by the Faculty of Clinical
Informatics (FCI) in the UK, the creation of a national competency framework
for Clinical Informatics is required for the definition of clinical
informaticians' professional attributes and skills. We aimed to
systematically review the academic literature relating to competencies,
skills and existing course curricula in the clinical and health related
informatics domains.
METHODS: Two independent reviewers searched Web of Science, EMBASE, ERIC,
PubMed and CINAHL. Publications were included if they reported details of
relevant competencies, skills and existing course curricula. We report
findings using the Preferred Reporting Items for Systematic Reviews and
Meta-Analysis (PRISMA) statement.
RESULTS: A total of 82 publications were included. The most frequently used
method was surveys (30 %) followed by narrative descriptions (28 %). Most of
the publications describe curriculum design (23 %) followed by competency
definition (18 %) and skills, qualifications & training (18 %). Core skills
surrounding data, information systems and information management appear to
be cross-cutting across the various informatics disciplines with
Bioinformatics and Pharmacy Informatics expressing the most unique
competency requirements.
CONCLUSION: We identified eight key domains that cut across the different
sub-disciplines of health informatics, including data, information
management, human factors, project management, research skills/knowledge,
leadership and management, systems development and evaluation, and
health/healthcare. Some informatics disciplines such as Nursing Informatics
appear to be further ahead at achieving widespread competency
standardisation. Attempts at standardisation for competencies should be
tempered with flexibility to allow for local variation and requirements.
