“…The vocabulary was also evaluated for quality, coverage, and usefulness of the simplification, for which the proposed resource outperforms all existing written resources. In another work, researchers propose to link medical terms to lay definitions 17 . The proposed system NoteAid incorporates two core components: CoDeMed, a lexical resource of lay definitions for medical terms, and MedLink, a computational unit that links medical terms to lay definitions.…”

Objectives: To analyze the content of publications within the medical Natural Language Processing (NLP) domain in 2018. Methods: Automatic and manual pre-selection of publications to be reviewed, and selection of the best NLP papers of the year. Analysis of the important issues. Results: Two best papers have been selected this year. One dedicated to the generation of multi- documents summaries and another dedicated to the generation of imaging reports. We also proposed an analysis of the content of main research trends of NLP publications in 2018. Conclusions: The year 2018 is very rich with regard to NLP issues and topics addressed. It shows the will of researchers to go towards robust and reproducible results. Researchers also prove to be creative for original issues and approaches.

“…Voice control was part of the initial design plan for the ALS-SimVR due to an indication from other health care settings [ 46 ]; however, implementing it is not without significant challenges. In addition to the computational and algorithmic challenges, there is the issue of a hugely diverse cohort of individuals, all of whom often use different language to convey the same information using expressions drawn from a diverse and specific lexicon [ 47 ].…”

Exploring User Needs in the Development of a Virtual Reality–Based Advanced Life Support Training Platform: Exploratory Usability Study

et al. 2020

Background Traditional methods of delivering Advanced Life Support (ALS) training and reaccreditation are resource-intensive and costly. Interactive simulations and gameplay using virtual reality (VR) technology can complement traditional training processes as a cost-effective, engaging, and flexible training tool. Objective This exploratory study aimed to determine the specific user needs of clinicians engaging with a new interactive VR ALS simulation (ALS-SimVR) application to inform the ongoing development of such training platforms. Methods Semistructured interviews were conducted with experienced clinicians (n=10, median age=40.9 years) following a single playthrough of the application. All clinicians have been directly involved in the delivery of ALS training in both clinical and educational settings (median years of ALS experience=12.4; all had minimal or no VR experience). Interviews were supplemented with an assessment of usability (using heuristic evaluation) and presence. Results The ALS-SimVR training app was well received. Thematic analysis of the interviews revealed five main areas of user needs that can inform future design efforts for creating engaging VR training apps: affordances, agency, diverse input modalities, mental models, and advanced roles. Conclusions This study was conducted to identify the needs of clinicians engaging with ALS-SimVR. However, our findings revealed broader design considerations that will be crucial in guiding future work in this area. Although aligning the training scenarios with accepted teaching algorithms is important, our findings reveal that improving user experience and engagement requires careful attention to technology-specific issues such as input modalities.

BackgroundAs accessibility to the internet has increased in society, many health care organizations have developed patient Web portals (PWPs), which can provide a range of self-management options to improve patient access. However, the available evidence suggests that they are used inefficiently and do not benefit patients with low health literacy. Asthma and chronic obstructive pulmonary disease (COPD) are common chronic diseases that require ongoing self-management. Moreover, patients with COPD are typically older and have lower health literacy.ObjectiveThis study aimed to obtain and present an overview of patients’ perspectives of PWPs to facilitate the development of a portal that better meets the needs of patients with asthma and COPD.MethodsWe performed a focus group study using semistructured interviews in 3 patient groups from the north of the Netherlands who were recruited through the Dutch Lung Foundation. Each group met 3 times for 2 hours each at a 1-week interval. Data were analyzed with coding software, and patient descriptors were analyzed with nonparametric tests. The consolidated criteria for reporting qualitative research were followed when conducting the study.ResultsWe included 29 patients (16/29, 55% male; mean age 65 [SD 10] years) with COPD (n=14), asthma-COPD overlap (n=4), asthma (n=10), or other respiratory disease (n=1). There was a large variation in the internet experience; some patients hardly used the internet (4/29, 14%), whereas others used internet >3 times a week (23/29, 79%). In general, patients were positive about having access to a PWP, considering access to personal medical records as the most important option, though only after discussion with their physician. A medication overview was considered a useful option. We found that communication between health care professionals could be improved if patients could use the PWP to share information with their health care professionals. However, as participants were worried about the language and usability of portals, it was recommended that language should be adapted to the patient level. Another concern was that disease monitoring through Web-based questionnaire use would only be useful if the results were discussed with health care professionals.ConclusionsParticipants were positive about PWPs and considered them a logical step. Today, most patients tend to be better educated and have internet access, while also being more assertive and better informed about their disease. A PWP could support these patients. Our participants also provided practical suggestions for implementation in current and future PWP developments. The next step will be to develop a portal based on these recommendations and assess whether it meets the needs of patients and health care providers.
