Content analysis and reliability of YouTube™ videos on clear aligner

Objectives: The aim of the present study is to evaluate the accuracy and reliability of the information provided in the videos about the clear aligner on the Youtube video platform, an internet information source. Materials and Methods: A video search was performed on the Youtube video platform using three keywords determined with the Google Trends application. After the videos were ranked based on their view counts, a total of 75 videos were analyzed, 47 being the first for each term. After applying the exclusion criteria (repetitive content, no audio content or title information, irrelevant to the topic, only promotional content, duration over 15 min, and addressing other orthodontic treatments), the remaining 47 videos were evaluated. Regarding the videos, the following parameters were recorded: View count, number of likes, number of dislikes, number of comments, video duration, and days since the uploaded date. A scoring system consisting of seven parameters was used to classify the video content quality as low and high. The video information and quality index were utilized to evaluate the quality of the videos universally. Statistical analyses were performed with Stata/IC computer program using Shapiro–Wilks, Kruskall–Wallis, Mann–Whitney U, and linear regression (Backward method) tests. Statistical significance value was set at P < 0.05. Results: Evaluation of the videos based on their upload source revealed that 27 videos were downloaded from individuals, ten videos from doctors and ten videos from commercial sources, and the number of subscribers to these sources varied significantly (P < 0.05). Evaluation of the videos based on the information provided, revealed that 32 videos had poor quality, ten videos had moderate quality and five videos had good quality information content, and the video durations varied significantly (P < 0.05). It was seen that of the 75 videos viewed, only 10 (13.3%) provided information of moderate-good quality. The number of likes was found to be the parameter that significantly affects the view count (P < 0.05). Conclusion: YouTube videos prove insufficient as a source of information on orthodontic treatment with clear aligner. Health-care professionals should be aware of online platforms to ensure that patients can access accurate information.

BACKGROUND:The aim of this study was to evaluate the information quality of YouTube videos on hallux valgus. METHODS:A YouTube search was performed using the keyword 'hallux valgus' to determine the first 300 videos related to hallux valgus. A total of 54 videos met our inclusion criteria and evaluated for information quality by using DISCERN, Journal of the American Medical Association (JAMA) and hallux valgus information assessment (HAVIA) scores. Number of views, time since the upload date, view rate, number of comments, number of likes, number of dislikes, video power index (VPI) values were calculated to determine video popularity. Video length (sec), video source and video content were also noted. The relation between information quality and these factors were statistically evaluated. RESULTS:The mean DISCERN score was 30.35{plus minus}11.56 (poor quality) (14-64), the mean JAMA score was 2.28{plus minus}0.96 (1-4), and the mean HAVIA score was 3.63{plus minus}2.42 (moderate quality) (0.5-8.5). Although videos uploaded by physicians had higher mean DISCERN, JAMA, and HAVIA scores than videos uploaded by non-physicians, the difference was not statistically significant. Additionally, view rates and VPI values were higher for videos uploaded by health channels, but the difference did not reach statistical significance. A statistically significant positive correlation was found between video length and DISCERN (r= 0.294, p= 0.028), and HAVIA scores (r= 0.326, p= 0.015). CONCLUSIONS:This present study demonstrated that the quality of information available on YouTube videos about hallux valgus was low and insufficient. Videos containing accurate information from reliable sources are needed to educate patients on hallux valgus, especially in less frequently mentioned topics such as postoperative complications and healing period.

Quality And Reliability

UNSTRUCTURED Introduction: Our aim is to assess the content quality and reliability of YouTube videos on bone tumors. Methods: We searched YouTube using the keyword “bone tumors,” and included in our study the first 50 videos listed. Two orthopedic surgeons analyzed the videos, and then, we examined them in terms of length, number of views and likes, and source. To evaluate their content quality, the Global Quality Score (GQS) (0–4), Journal of the American Medical Association (JAMA) (0–5), and DISCERN (15–75) scoring systems were used; based on these, the obtained data were statistically analyzed. Results: Of the 50 videos analyzed, four (8%) included animation, while 46 (92%) did not; 12 (24%) were uploaded by doctors, 23 (46%) by health channels, 10 (20%) by universities, three (6%) by clinics, and one (2%) each by a hospital and a trainer. The average video length was 16 minutes 18 seconds (38-6088 seconds), average number of views 14,856.24, and average number of likes 130.50 (1-1448). The mean scores of GQS, JAMA, and DISCERN were 2.22 (1-4), 2.12 (1-3), and 33.48 (15-75), respectively. There was no statistical significance in the scores and video length, or the number of likes and views between the two researchers. Discussion: YouTube videos on bone tumors have low content quality. Improvement of the same will help dispense correct information to patients, so that they can continue their treatment. We believe that patient treatment compliance can be increased by accelerating the patient’s preparation and adaptation process for treatment with accurate information.

Objective: To predict the quality of anticoagulation control in patients with atrial fibrillation (AF) receiving warfarin in Thailand. Materials and Methods: The present study retrospectively recruited Thai AF patients receiving warfarin for three months or longer between June 2012 and December 2017 in Central Chest Institute of Thailand. The patients were classified into those with SAMe-TT₂R₂ of 2 or less, and 3 or more. The Chi-square test or Fisher’s exact test was used to compare the proportion of the patients with poor time in therapeutic range (TTR) between the two groups of SAMe-TT₂R₂ score. The discrimination performance of SAMe-TT₂R₂ score was demonstrated with c-statistics. Results: Ninety AF patients were enrolled. An average age was 69.89±10.04 years. Most patients were persistent AF. An average CHA₂DS₂-VASc, SAMe-TT₂R₂, and HAS-BLED score were 3.68±1.51, 3.26±0.88, and 1.98±0.85, respectively. The present study showed the increased proportion of AF patients with poor TTR with higher SAMe-TT₂R₂ score. The AF patients with SAMe-TT₂R₂ score of 3 or more had a larger proportion of patients with poor TTR than those with SAMe-TT₂R₂ score of 2 or less with statistical significance when TTR was below 70% (p=0.03) and 65% (p=0.04), respectively. The discrimination performance of SAMe-TT₂R₂ score was demonstrated with c-statistics of 0.60, 0.59, and 0.55 when TTR was below 70%, 65% and 60%, respectively. Conclusion: Thai AF patients receiving warfarin had a larger proportion of patients with poor TTR when the SAMe-TT₂R₂ score was higher. The score of 3 or more could predict poor quality of anticoagulation control in those patients.

Quality Of Research

This paper reminds readers of the absurdity of statistical significance testing, despite its continued widespread use as a supposed method for analysing numeric data. There have been complaints about the poor quality of research employing significance tests for a hundred years, and repeated calls for researchers to stop using and reporting them. There have even been attempted bans. Many thousands of papers have now been written, in all areas of research, explaining why significance tests do not work. There are too many for all to be cited here. This paper summarises the logical problems as described in over 100 of these prior pieces. It then presents a series of demonstrations showing that significance tests do not work in practice. In fact, they are more likely to produce the wrong answer than a right one. The confused use of significance testing has practical and damaging consequences for people's lives. Ending the use of significance tests is a pressing ethical issue for research. Anyone knowing the problems, as described over one hundred years, who continues to teach, use or publish significance tests is acting unethically, and knowingly risking the damage that ensues.

Abstract Background YouTube has become an important educational platform. For biomedical students the site is a primary information source for informational and instructional videos on a variety of medical topics.This study examined the educational quality of instructional lumbar puncture procedure videos on YouTube.Methods The search strings “lumbar puncture medical procedure” and “spinal tap medical procedure” were used. The first 100 videos for each search string were assessed for eligibility. Video characteristics were documented. To evaluate the popularity of the videos the Video Power Index was calculated. Four validated checklists were used for video assessment: Lumbar Puncture Assessment Tool, reliability score, Global Quality Score, Attractiveness and Understandability score.Results Lumbar puncture videos had a median ratio of 8,90 views/day, 0,04 likes/day and a video power index of 14,44, which was lower compared to other categories of instructional videos (CPR and cake baking). The mean LumPAT score was 34/55, with only three videos scoring at least 44/55, the pass ratio of this assessment. The median reliability score was 3/4, the median GQS 3/5 (moderate quality) and the median AU score 6,5/8. Significant correlations were found between the LumPAT score and the video length (p = 0,003), the GQS (p < 0,001) and the AU score (p = 0,01).Conclusions In this study, only three out of the 23 videos passed the LumPAT score. The majority of the instructional videos are not suitable for the training of health care professionals and students in performing a lumbar puncture procedure.

<p>Good patient safety culture of healthcare professionals brings about fine consequences for patients. This study, therefore, aimed in evaluating the current status and predictors of safety culture among healthcare workers in Mekelle Zone hospitals, Tigray, Northern Ethiopia. A cross-sectional survey was conducted among 325 healthcare workers in three hospitals of Mekelle city from February to May, 2017. Simple random sampling technique was employed to select study subjects. Data was analyzed using SPSS. Logistic regression was used to determine the predictors of patient safety culture among healthcare workers at 95% confidence level and 5% level of significance. Statistical significance was set at p <0.05. Of the 325 Healthcare workers, 21.6% rated the culture of patient safety as satisfactory and 78.4% rated as unsatisfactory. Old aged healthcare workers (AOR=21.9, 95% of CI: 2.51-61.69) and ‘hospital management support for patient safety’ (AOR=2.68, 95% CI=1.06-6.79) were strong predictor of satisfactory patient safety culture. Satisfactory patient safety culture grade obtained was only 21.6%, indicating that health care professionals are not delivering patient centered service and there is a lot of work to be done in the hospitals to improve culture of patient safety among healthcare workers. </p>

Information e-services are useful for exchanging information among many users, whether human or automated agent; however, e-service users are susceptible to risk of inaccurate information, since users have no traditional face-to-face interaction or past relational history with information providers. To encourage use of information e-services, individuals must have technology to assess information accuracy and information source trustworthiness. This research permits automated e-service users—here called agents—acting on behalf of humans, to employ policies, or heuristics, for predicting information accuracy when numerous pieces of information are received from multiple sources. These intuitive policies draw from human strategies for evaluating the trustworthiness of information to not only identify accurate information, but also distinguish untrustworthy information providers. These policies allow the agent to build a user’s confidence in the trust assessment technology by creating justifications for trust assessment decisions and identifying particular policies integral to a given assessment decision.

The children emergency room (ER) is regarded as an essential section of hospitals and other healthcare settings where immediate medical and surgical care is given to children in need of urgent care. The conditions of the emergency room and the quality of service by the emergency room staff has been described as a major determinant of the socio-medical outcome of patients and their relatives. This is a hospital based cross-sectional carried out in the Children Emergency Room (CHER) of the Enugu State University Teaching Hospital, Enugu Nigeria. Parents and care-givers that presented with their sick children to the ER department were successively enrolled after obtaining consent. Information on their assessment of certain aspects of the emergency room environment and quality of service received from medical and administrative personnel working in the emergency room was obtained using a 5-point Likert assessment scale. Results were reported using frequencies, percentages and chisquare were applicable. Statistical significance was set at P≤0.05. Over half (59%) of the 83 respondents that presented to the emergency room during the study period were self-referrals and all (95.2%), but four respondents noted a significant improvement in the condition of their sick children following management in the emergency room. In all parameters assessed, most respondents rated the emergency room conditions as moderate in noise level 69 (83.1), crowdedness 65 (78.3), comfort 49 (59.0) and cleanliness 41 (49.4) with an overall point score of 2.97±0.33 out of a possible five. Doctors were on average rated better than nurses and record clerk staff in politeness (P=0.001), patience (P=0.002), efficiency (P=0.002), and adequate explanation of procedures (P=0.001) while nurses were rated better than record staff in explanation of procedures to their patient (P=0.05) but not in politeness (P=0.894), patience (P=0.505) and efficiency (P=0.982). The rating of record clerks was significantly affected by the socio-economic class of respondents (P=0.036) but not by gender (P=0.252) or age of respondents (P=0.123). None of the respondents’ socio-demographic factors significantly determined their rating for the emergency room conditions and the quality of service by doctors or nurses. There is a need for a continued review of emergency room conditions in addition to training and re-training of staff in the children emergency room. This not only helps improve health outcomes but may also significantly reduce the duration of stay in the emergency room that in turn reduces congestion and the burden on the healthcare system.

Systematic Sampling Method

Background: For optimum delivery of service, an establishment needs to ensure a safe and secure environment. In 2011, the South African government promulgated the National Core Standards for Health Establishments for safety and security for all employees in all establishments. Little is known about whether these standards are being complied to.Aim and setting: To assess the perceptions of health care professionals (HCPs) on safety and security at Odi District Hospital.Methodology: A sample of 181 out of a total of 341 HCPs was drawn through a systematic sampling method from each HCP category. Data were collected through a self-administered questionnaire. The SPSS® statistical software version 22 was used for data analysis. The level of statistical significance was set at < 0.05.Results: There were more female respondents than male respondents (136; 75.10%). The dominant age group was 28–47 years (114; 57.46%). Perceptions on security personnel, their efficiency and the security system were significantly affirmed (p = 0.0001). The hospital infrastructure, surroundings and plan in emergencies were perceived to be safe (p < 0.0001). The hospital lighting system was perceived as inadequate (p = 0.0041). Only 36 (20.2%) HCPs perceived that hospital authorities were concerned about employees’ safety (p < 0.0001).Conclusion: HCPs had positive perceptions regarding the hospital’s security system. Except for the negative perceptions of the lighting system and the perceived lack of hospital authorities’ concern for staff safety, perceptions of the HCPs on the hospital working environment were positive. The hospital authorities need to establish the basis of negative perceptions and enforce remedial measures to redress them.
