Qualitative assessment of YouTube videos as a source of patient information for cochlear implant surgery.

BACKGROUND: YouTube is increasingly used as a source of healthcare information. This study evaluated the quality of videos on YouTube about cochlear implants. METHODS: YouTube was searched using the phrase 'cochlear implant'. The first 60 results were screened by two independent reviewers. A modified Discern tool was used to evaluate the quality of each video. RESULTS: Forty-seven videos were analysed. The mean overall Discern score was 2.0 out of 5.0. Videos scored higher for describing positive elements such as the benefits of a cochlear implant (mean score of 3.4) and scored lower for negative elements such as the risks of cochlear implant surgery (mean score of 1.3). CONCLUSION: The quality of information regarding cochlear implant surgery on YouTube is highly variable. These results demonstrated a bias towards the positive attributes of cochlear implants, with little mention of the risks or uncertainty involved. Although videos may be useful as supplementary information, critical elements required to make an informed decision are lacking. This is of particular importance when patients are considering surgery.

Development and validation of a recommended checklist for assessment of surgical videos quality: the LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool.

INTRODUCTION: There has been a constant increase in the number of published surgical videos with preference for open-access sources, but the proportion of videos undergoing peer-review prior to publication has markedly decreased, raising questions over quality of the educational content presented. The aim of this study was the development and validation of a standard framework for the appraisal of surgical videos submitted for presentation and publication, the LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool. METHODS: An international committee identified items for inclusion in the LAP-VEGaS video assessment tool and finalised the marking score utilising Delphi methodology. The tool was finally validated by anonymous evaluation of selected videos by a group of validators not involved in the tool development. RESULTS: 9 items were included in the LAP-VEGaS video assessment tool, with every item scoring from 0 (item not presented in the video) to 2 (item extensively presented in the video), with a total marking score ranging from 0 to 18. The LAP-VEGaS video assessment tool resulted highly accurate in identifying and selecting videos for acceptance for conference presentation and publication, with high level of internal consistency and generalisability. CONCLUSIONS: We propose that peer review in adherence to the LAP-VEGaS video assessment tool could enhance the overall quality of published video outputs.

Qualitative and quantitative assessment of magnetic vestibular stimulation in humans.

The sensation of phantom motion or exhibition of bodily sway is often reported in the proximity of an MR scanner. It is proposed that the magnetic field stimulates the vestibular system. There are a number of possible mechanisms responsible, and the relative contributions of susceptibility on the otolithic receptors and the Lorentz force on the cupulae have not yet been explored. This exploratory study aims to investigate the impact of being in the proximity of a 7.0 T MR scanner.The modified clinical test of sensory interaction on balance (mCTSIB) was used to qualitatively ascertain whether or not healthy control subjects who passed the mCTSIB in normal conditions 1) experienced subjective sensations of dizziness, vertigo or of leaning or shifting in gravity when in the magnetic field and 2) exhibited visibly increased bodily sway whilst in the magnetic field compared to outside the magnetic field. Condition IV of the mCTSIB was video recorded outside and inside the magnetic field, providing a semi-quantitative measure of sway.For condition IV of the mCTSIB (visual and proprioceptive cues compromised), all seven locations/orientations around the scanner yielded significantly more sway than at baseline (p < 0.01 FDR). A Student's t-test comparing the RMS velocity of a motion marker on the upper arm during mCTSIB condition IV showed a significant increase in the amount of motion exhibited in the field (T = 2.59; d.f. = 9; p = 0.029) compared to outside the field.This initial study using qualitative measures of sway demonstrates that there is evidence for MR-naïve individuals exhibiting greater sway while performing the mCTSIB in the magnetic field compared to outside the field. Directional polarity of sway was not significant. Future studies of vestibular stimulation by magnetic fields would benefit from the development of a sensitive, objective measure of balance function, which can be performed inside a magnetic field.

Construction and validation of an educational video for human papillomavirus vaccination.

OBJECTIVES: to validate an educational video aimed at the adhesion of human papillomavirus vaccination. METHODS: a methodological study, where the knowledge about the theme and the technology to be constructed in six focal groups was identified; a theoretical framework was set up and the existing videos were uploaded. After that, pre-production, production and post-production were followed. In validation of content, 22 specialists participated, and in appearance, ten adolescents, ten mothers, ten teachers and ten audiovisual professionals. Absolute frequency, Binomial Test, and Content Validity Index were used. RESULTS: agreement was satisfactory in most items. Regarding relevance, 20 items had indices above 0.80 among judges. Assessment was positive among girls and mothers. Only three items had indices less than 0.80 among teachers and video professionals. CONCLUSIONS: the educational video was validated, conferring credibility to contribute to educational actions and improve vaccination indexes.

'Both useful in their own way': Video podcasts and typed solutions as feedback on undergraduate pharmaceutical calculations skills assessment.

INTRODUCTION: Accurately completing pharmaceutical calculations is a core professional skill for pharmacists. To date, few studies have focused on to providing feedback on calculations, or the role of technology in feedback provision. This study aimed to develop a theory-informed video podcast-based method of providing formative feedback and evaluate student perceptions. METHODS: First-year pharmacy students (n = 53) completed a formative pharmaceutical calculations assessment. Two forms of feedback were designed and evaluated; typed solutions (traditional format commonly used/seen in textbooks) and video podcasts informed by instructional design theory (novel format). RESULTS: A survey was completed by 70% (37/53) of students. Specific features of video podcasts reported useful included hearing reasoning, and the ability to pause and rewind. Most (76%) reported positive attitudes towards video podcasts, considered them useful (75%) and helpful for learning (79%). A comparable number (76% and 71% respectively) felt positively about typed solutions. The majority (51%) preferred to receive both types rather than podcasts alone (24%), or typed solutions alone (8%). Free-text responses indicated both were used in different ways; typed solutions for quick verification and video podcasts for clarification. CONCLUSIONS: Video podcasts appear to be a potentially helpful additional method of delivering feedback that afford specific advantages. They can be readily developed by faculty with minimal expense/difficulty. However, as respondents indicated that they used both kinds of feedback in different ways to support their learning, and indicated a preference to receive both types, they should be considered an addition rather than replacement for typed solutions.

Educational assessment of the major lower limb amputations videos on YouTube.

OBJECTIVE: Videos of surgical procedures are viewed by some as potential training resources for surgeons and residents. However, there is little evidence on the effectiveness of surgical videos on learning and understanding complex three-dimensional surgical procedures. Lower extremity amputation is a complex surgery, and many residents and surgeons have low exposure to this type of procedures. This paper investigates the educational quality of lower extremity amputation videos posted on YouTube. METHODS: The search was limited to the first 100 videos. Full-length videos of any major lower limb amputation or disarticulation were included. Key basic video data such as title, YouTube address (http://), country of origin, channel source, uploading date, video duration time, number of views, number of up-voters and number of down-voters were collected. An educational assessment tool has been developed specifically for limb amputations. It consists in 11 items: three general and eight amputation-specific, each having a maximum score of 2. RESULTS: In total, 13 videos met the inclusion criteria for final analysis. Four videos reported the surgical technique of above knee amputation, two reported that of knee disarticulation and the remaining seven videos described below knee amputation. The average score (±SD) was 12.77 ± 5.2 yielding an average grade close to "Fair." A high level of concordance was found between the two assessors (κ = 0.79). No correlation was found between educational assessment tool score and the pre-set variables (r = 0.6, R2 = 35.4%, F = 1.09, P = 0.4). CONCLUSIONS: Most videos describing lower extremity amputation techniques were found to be of low-to-moderate quality. Only 4 out of 13 (30.7%) had an excellent educational and technical quality. Surgeons and surgical residents should be aware that not all posted videos on YouTube are beneficial. High educational quality videos are needed since many surgeons and residents have a low exposure to such surgeries.

Can You Trust What You Watch? An Assessment of the Quality of Information in Aesthetic Surgery Videos on YouTube.

BACKGROUND: Videos on YouTube can be posted without regulation or content oversight. Unfortunately, many patients use YouTube as a resource on aesthetic surgery, leading to misinformation. Currently, there are no objective assessments of the quality of information on YouTube about aesthetic surgery. METHODS: YouTube was queried for videos about the 12 most common aesthetic surgical procedures, identified from the 2015 American Society of Plastic Surgeons procedural statistics between May and June of 2016. The top 25 results for each search term were scored using the modified Ensuring Quality Information for Patients criteria based on video structure, content, and author identification. Average Ensuring Quality Information for Patients score, view count, and video duration were compared between authorship groups. RESULTS: A total of 523 videos were graded after excluding duplicates. The mean modified Ensuring Quality Information for Patients score for all videos was 13.1 (SE, 0.18) of a possible 27. The videos under the search "nose reshaping" had the lowest mean score of 10.24 (SE, 0.74), whereas "breast augmentation" had the highest score of 15.96 (SE, 0.65). Physician authorship accounted for 59 percent of included videos and had a higher mean Ensuring Quality Information for Patients score than those by patients. Only three of the 21 search terms had a mean modified Ensuring Quality Information for Patients score meeting criteria for high-quality videos. CONCLUSIONS: The information contained in aesthetic surgery videos on YouTube is low quality. Patients should be aware that the information has the potential to be inaccurate. Plastic surgeons should be encouraged to develop high-quality videos to educate patients.

Creation and validation of an educational video for deaf people about cardiopulmonary resuscitation.

OBJECTIVE: to create and validate an educational video for teaching deaf students about cardiopulmonary resuscitation. METHOD: methodological study consisting in the creation of an educational video, validation of its content by 22 nurses with expertise in cardiorespiratory arrest, and evaluation by 16 deaf students. For data collection, the following validated instruments were used: the Instrument for Validation of Educational Content used for the validation by nurses and the Assistive Technology Assessment Questionnaire for the evaluation by deaf students. The criterion for validation was concordance higher than 80%, analyzed through the content validation index and binomial test. RESULTS: the final version of the video lasted seven minutes and thirty seconds, covered the steps that should be performed by a lay person to help a victim of cardiorespiratory arrest, presented animations and the narration in the Brazilian sign language. All the items obtained agreement among nurses and of among deaf students equal or superior to 80%. CONCLUSION: the video was considered to present valid content by the judges and comprehensible content by deaf students. Thus the video represents an inclusive technology for health education of deaf people about cardiopulmonary resuscitation.

Inexpensive, scalable camera system for tracking rats in large spaces.

Most studies of neural correlates of spatial navigation are restricted to small arenas (≤1 m2) because of the limits imposed by the recording cables. New wireless recording systems have a larger recording range. However, these neuronal recording systems lack the ability to track animals in large area, constraining the size of the arena. We developed and benchmarked an open-source, scalable multicamera tracking system based on low-cost hardware. This "Picamera system" was used in combination with a wireless recording system for characterizing neural correlates of space in environments of sizes up to 16.5 m2. The Picamera system showed substantially better temporal accuracy than a popular commercial system. An explicit comparison of one camera from the Picamera system with a camera from the commercial system showed improved accuracy in estimating spatial firing characteristics and head direction tuning of neurons. This improved temporal accuracy is crucial for accurately aligning videos from multiple cameras in large spaces and characterizing spatially modulated cells in a large environment. NEW & NOTEWORTHY Studies of neural correlates of space are limited to biologically unrealistically small spaces by neural recording and position tracking hardware. We developed a camera system capable of tracking animals in large spaces at a high temporal accuracy. Together with the new wireless recording systems, this system facilitates the study of neural correlates of space at biologically relevant scale. This increased temporal accuracy of tracking also improves the estimates of spatiotemporal correlates of neural activity.

The assessment of online health videos for surgery in Crohn's disease.

AIM: YouTube™ is an open-access, nonpeer-reviewed video-hosting site and is used as a source of publicly available healthcare information. This study aimed to assess the thematic content of the most viewed videos relating to surgery and Crohn's disease and to explore the viewer interactions with these videos. METHOD: A search of YouTube™ was carried out using one search string. The 50 most viewed videos were identified and categorized by source and content themes and assessed for viewer interactions. Video comments were used to describe the usefulness of the video content to viewers. RESULTS: The majority of videos were uploaded by patients (n = 21).The remainder were uploaded by individual healthcare professionals (n = 9), hospital/speciality associations (n = 18) and industry (n = 2). The median number of likes for patient videos was significantly higher than for hospital/speciality association videos (P < 0.001). Patient videos received more comments praising the video content (n = 27) and more comments asking for further information (n = 14). The median number of likes for 'experience of surgery' (P < 0.001) and 'experience of disease' (P = 0.0015) themed videos were significantly higher than for 'disease management' themed videos. CONCLUSION: Crohn's disease patients use YouTube™ as a surgical information source. The content of patient-sourced videos focused on surgical and disease experience, suggesting that these themes are important to patients. Current patient developed videos provide limited information, as reflected by viewers requesting further information. Storytelling patient-centred videos combined with clinical evidence may be a good model for future videos.

Validation of the imperial college surgical assessment device for spinal anesthesia.

BACKGROUND: Traditionally, technical proficiency for spinal anesthesia has been assessed using observational scales such as global rating scales or task specific checklists. However more objective metrics are required in order to improve novice's training programs. The aim of this study is to validate the hand motion analysis of the Imperial College Surgical Assessment Device (ICSAD) in a simulated model of spinal anesthesia. METHODS: Three groups of physicians with different levels of experience were video recorded performing a spinal anesthesia in a simulated lumbar puncture torso. Participants' technical performance was assessed with ICSAD, a Global Rating Scale (GRS) and a specific Checklist. Differences between the 3 groups were determined by Kruskal-Wallis test with post hoc Dunn's correction for multiple comparisons. Spearman correlation coefficient between ICSAD variables and the scores of the observational scales were calculated to establish concurrent validity. RESULTS: Thirty subjects participated in the study: ten novice (first year residents), 10 intermediate (third year residents) and 10 experts (attending anesthesiologists). GRS scores were significantly higher in experts, than intermediates and novices. Regarding total path length, number of movements and procedural time measured with ICSAD, all groups had significant differences between them (p = 0.026, p = 0.045 and p = 0.005 respectively). Spearman correlation coefficient was -0,46 (p = 0.012) between total path length measured with ICSAD and GRS scores. CONCLUSIONS: This is the first validation study of ICSAD as an assessment tool for spinal anesthesia in a simulated model. Using ICSAD can discriminate proficiency between expert and novices and correlates with previously validated GRS. Its use in the assessment of spinal anesthesia proficiency provides complementary data to existing tools. Our results could be used to design future training programs with reliable goals to accomplish.

Health behaviour information provided to clients during midwife-led prenatal booking visits: Findings from video analyses.

OBJECTIVE: to quantify to what extent evidence-based health behaviour topics relevant for pregnancy are discussed with clients during midwife-led prenatal booking visits and to assess the association of client characteristics with the extent of information provided. DESIGN: quantitative video analyses. SETTING AND PARTICIPANTS: 173 video recordings of prenatal booking visits with primary care midwives and clients in the Netherlands taking place between August 2010 and April 2011. MEASUREMENTS: thirteen topics regarding toxic substances, nutrition, maternal weight, supplements, and health promoting activities were categorized as either 'never mentioned', 'briefly mentioned', 'basically explained' or 'extensively explained'. Rates on the extent of information provided were calculated for each topic and relationships between client characteristics and dichotomous outcomes of the extent of information provided were assessed using Generalized Linear Mixed Modelling. FINDINGS: our findings showed that women who did not take folic acid supplementation, who smoked, or had a partner who smoked, were usually provided basic and occasionally extensive explanations about these topics. The majority of clients were provided with no information on recommended weight gain (91.9%), fish promotion (90.8%), caffeine limitation (89.6%), vitamin D supplementation (87.3%), physical activity promotion (81.5%) and antenatal class attendance (75.7%) and only brief mention of alcohol (91.3%), smoking (81.5%), folic acid (58.4) and weight at the start of pregnancy (52.0%). The importance of a nutritious diet was generally either never mentioned (38.2%) or briefly mentioned (45.1%). Nulliparous women were typically given more information on most topics than multiparous women. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: although additional information was generally provided about folic acid and smoking, when relevant for their clients, the majority of women were provided with little or no information about the other health behaviours examined in this study. Midwives may be able to improve prenatal health promotion by providing more extensive health behaviour information to their clients during booking visits.

The reliability and criterion validity of 2D video assessment of single leg squat and hop landing.

The objective was to assess the intra-tester, within and between day reliability of measurement of hip adduction (HADD) and frontal plane projection angles (FPPA) during single leg squat (SLS) and single leg landing (SLL) using 2D video and the validity of these measurements against those found during 3D motion capture. 15 healthy subjects had their SLS and SLL assessed using 3D motion capture and video analysis. Inter-tester reliability for both SLS and SLL when measuring FPPA and HADD show excellent correlations (ICC2,1 0.97-0.99). Within and between day assessment of SLS and SLL showed good to excellent correlations for both variables (ICC3,1 0.72-91). 2D FPPA measures were found to have good correlation with knee abduction angle in 3-D (r=0.79, p=0.008) during SLS, and also to knee abduction moment (r=0.65, p=0.009). 2D HADD showed very good correlation with 3D HADD during SLS (r=0.81, p=0.001), and a good correlation during SLL (r=0.62, p=0.013). All other associations were weak (r<0.4). This study suggests that 2D video kinematics have a reasonable association to what is being measured with 3D motion capture.

Assessment of personality-related levels of functioning: a pilot study of clinical assessment of the DSM-5 level of personality functioning based on a semi-structured interview.

BACKGROUND: The personality disorder categories in the Diagnostic and Statistical Manual of Mental Disorders IV have been extensively criticized, and there is a growing consensus that personality pathology should be represented dimensionally rather than categorically. The aim of this pilot study was to test the Clinical Assessment of the Level of Personality Functioning Scale, a semi-structured clinical interview, designed to assess the Level of Personality Functioning Scale of the DSM-5 (Section III) by applying strategies similar to what characterizes assessments in clinical practice. METHODS: The inter-rater reliability of the assessment of the four domains and the total impairment in the Level of Personality Functioning Scale were measured in a patient sample that varied in terms of severity and type of pathology. Ratings were done independently by the interviewer and two experts who watched a videotaped Clinical Assessment of the Level of Personality Functioning Scale interview. RESULTS: Inter-rater reliability coefficients varied between domains and were not sufficient for clinical practice, but may support the use of the interview to assess the dimensions of personality functioning for research purposes. CONCLUSIONS: While designed to measure the Level of Personality Functioning Scale with a high degree of similarity to clinical practice, the Clinical Assessment of the Level of Personality Functioning Scale had weak reliabilities and a rating based on a single interview should not be considered a stand-alone assessment of areas of functioning for a given patient.

'How to stop a nosebleed': an assessment of the quality of epistaxis treatment advice on YouTube.

OBJECTIVE: Video hosting websites are increasingly being used to disseminate health education messages. This study aimed to assess the quality of advice contained within YouTube videos on the conservative management of epistaxis. METHOD: YouTube.com was searched using the phrase 'how to stop a nosebleed'. The first 50 videos were screened. Objective advice scores and subjective production quality scores were attributed by independent raters. RESULTS: Forty-five videos were analysed. The mean advice score was 2.0 out of 8 and the mean production quality score was 1.6 out of 3. There were no correlations between a video's advice score and its search results rank (ρ = -0.28, p = 0.068), its view count (ρ = 0.20, p = 0.19) or its number of 'likes' (ρ = 0.21, p = 0.18). CONCLUSION: The quality of information on conservative epistaxis management within YouTube videos is extremely variable. A high search rank is no indication of video quality. Many videos proffer inappropriate and dangerous 'alternative' advice. We do not recommend YouTube as a source for patient information.

Quality Assessment of Video Mediastinoscopy Performed for Staging in Non-Small Cell Lung Cancer.

Background Mediastinoscopy is considered to be the gold standard for mediastinal staging for patients with non-small cell lung cancer (NSCLC). The diagnostic value depends on how this procedure is performed, which has resulted in drafting a guideline by the European Society of Thoracic Surgery (ESTS). Biopsy of at least stations 4R, 4L, 7, and if present stations 2R and 2L, is recommended. The objective of this study is to assess the quality of the mediastinoscopies performed in our hospital for NSCLC. Methods Medical records of 102 consecutive patients with suspected or proven NSCLC and a performed cervical mediastinoscopy between January 2009 and November 2014 were analyzed in a retrospective cohort study. The number of biopsied stations and complications has been prospectively documented, together with their clinical data. Results Cervical mediastinoscopy was performed in 102 patients and in 51 (50%) patients biopsy was taken of stations 4R, 4L, and 7. N2/N3 disease emerged more significantly (p < 0.05) if biopsies were taken of at least the paratracheal stations 4R/4L and the subcarinal region. The incidence of major complications was 3.9%. Conclusion In our clinic, 50% of the mediastinoscopies performed are executed following the ESTS guidelines. Our results subscribe the need to biopsy at least the paratracheal stations 4L/4R and the subcarinal region to obtain a reliable assessment of the mediastinum.

A quality assessment of respiratory auscultation material on YouTube.

YouTube contains a large volume of medical educational material. This study assessed the quality of respiratory auscultation videos contained in YouTube. Videos were searched for using the terms 'breath sounds', 'respiratory sounds', 'respiratory auscultation' and/or 'lung sounds'. In total, 6,022 videos were located, 36 of which were considered suitable for scoring for video accuracy, comprehensiveness and quality. The average score was 3.32/6 (55.3% ± 1.30). Video score correlated with time-adjusted YouTube metadata: hits per day (0.496, p=0.002) and likes per day (0.534, p=0.001). Video score also correlated with the first search page on which the video was located in the 'breath sounds' and 'lung sounds' searches (-0.571, p=0.001; -0.445, p=0.014, respectively). The quality of videos was variable. Correlation between video score and some metadata values suggests that there is value for their use in judging video quality. However, the large number of videos found and inability to filter these results quickly makes locating educational content difficult.

Evaluating the role of content in subjective video quality assessment.

Video quality as perceived by human observers is the ground truth when Video Quality Assessment (VQA) is in question. It is dependent on many variables, one of them being the content of the video that is being evaluated. Despite the evidence that content has an impact on the quality score the sequence receives from human evaluators, currently available VQA databases mostly comprise of sequences which fail to take this into account. In this paper, we aim to identify and analyze differences between human cognitive, affective, and conative responses to a set of videos commonly used for VQA and a set of videos specifically chosen to include video content which might affect the judgment of evaluators when perceived video quality is in question. Our findings indicate that considerable differences exist between the two sets on selected factors, which leads us to conclude that videos starring a different type of content than the currently employed ones might be more appropriate for VQA.
