However, while recognizing the value of YouTube videos for patient education, most existing work in health communication has evaluated video understandability manually which is not scalable, replicable or efficient. In this study, we draw on the Patient Education Material Assessment Tool (PEMAT), a systematic approach for audio-visual educational materials assessment, to develop an automated video classification solution that is also generalizable. Extracting video features and metadata from YouTube, we develop an algorithmic approach employing PEMAT-based patient education constructs, annotations from domain experts and co-training methods from machine learning to assess the understandability of diabetes videos for patient education. The co-training approach significantly improves the video understandability classification performance in comparison to three widely used benchmark machine learning models. We further examine the impact of understandability on several dimensions of collective engagement with videos. A challenge in evaluating collective engagement with understandable videos is that there could be content that is not medically validated but yet engage users. Hence, we consider the simultaneous impact of understandability and validated medical information in a video on collective engagement by conducting a multiple-treatment propensity score based matching approach that allows us to implement a quasi-randomization research design. While confirming common assessments of the relationship between user engagement and understandability of education materials, our analysis quantifies these effects using actual viewing data in the specific context of understandability of complex medical information encoded in patient education videos found on YouTube. Implications for research and practice are discussed.","PeriodicalId":226395,"journal":{"name":"Medical Education eJournal","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126466108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presentation of health information is manipulated to discover how the judged severities of health states respond to these presentation changes. Specifically, splitting up an EQ-5D dimension into two increases its weight in severity judgments, and combining two dimensions reduces their weight, even though the information provided is unchanged. This result implies that preferences are malleable. Telling participants the name of the health state significantly alters the judged severities of some health states, which suggests that the standard information presented in an HR-QoL estimation study may not adequately capture all relevant aspects of health states as perceived by members of the public. This effect is shown to be driven by fear of certain health states, and the implications for allocative policymaking are discussed. Behaviour across all three experiments demonstrates systematic deviations from normatively ideal behaviour, but the conclusions are optimistic: understanding where standard approaches fall short is necessary for the design of behaviourally realistic yet tractable models and appropriate survey designs to better understand the impacts of different health states on people’s anticipated quality of life.","PeriodicalId":226395,"journal":{"name":"Medical Education eJournal","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133351990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The endophilin BAR domain has amphipathic helices, and degrees of insertion of these helices by mutations or phosphorylation cause a switch between tubule and vesicle formation. However, the membrane phospholipid properties causing switching remains unclear. We examined membrane deformation by endophilin using liposomes from various sources, including the plasma membrane, and found that endophilin vesiculated plasma membrane-derived liposomes. Endophilin vesiculated the plasma membrane-inspired reconstituted liposomes, which contained a small amount of charged phospholipids that resulted in uneven binding of endophilin. In contrast, the increase of charged phospholipids including phosphatidylinositol 4,5-bisphosphate resulted in tubulation by the increased binding of endophilin. Either tubulation or vesiculation required certain packing defects by the unsaturated acyl chains of phospholipids. Therefore, endophilin binding to membrane based on membrane charge density was the switch between tubulation and vesiculation, suggesting the importance of charge density in membrane deformation.","PeriodicalId":226395,"journal":{"name":"Medical Education eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121163248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: Investigating factors affecting physicians' compliance and evaluating associated cost savings. Design: A cross-sectional observational study of all physicians in the HMO's clinics from June 2005 to February 2006. Setting: Recording physician ID, initial drug choice, final drug choice, elapsed time between initial and final choices, and pharmacological details. Participants: Out of 2120 physicians, 647 physicians met the inclusion criteria. They prescribed 1.21 million prescriptions. Intervention: Transparently recording physicians’ response to HMO-recommended drug substitutes within a drug-prescription sub-system of an electronic medical record. Measurements: Compliance pattern, factors affecting compliance, and cost savings associated with compliance. Results: Thirty percent of prescriptions did not comply with substitute recommendations. Compliance was most strongly affected by the substitute type, whether generic or therapeutic. Physician workload and age were found second and third in effect magnitude. Compliance was found to be non-automatic, selective and deliberate, suggesting that maintaining quality of care guides physicians in the prescription process. At least 4% of costs for prescribed drugs were saved as a result of compliance with substitute recommendations. Conclusions: Physicians selectively complied with electronic recommendations to substitute less costly for more costly drugs. Compliance was neither automatic nor thoughtless and entailed cost containment with possibly marginal compromise on quality of care or none at all, as compliance mostly involved substituting generic for patent drugs. We strongly feel that the results can be generalized to other HMOs as well.","PeriodicalId":226395,"journal":{"name":"Medical Education eJournal","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128489577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
