The development and pilot of a novel mobile application to assess clinician perception of workload and work environment.

Traditional measures of workload such as wRVUs may not be adequate to understand the impact of workload on key outcomes. The objective of this study was to develop a mobile application to assess, in near real time, clinicians' perception of workload and work environment. We developed the GrittyWork™ application (GW App) using the Chokshi and Mann process model for user-centered digital development. Study occured at a single academic medical center with hospitalist clinicians. Measures included the System Usability Scale (SUS), use measures from GW App, electronic health record (EHR) event log data and note counts, and qualitative interviews. From October 28, 2022 to November 3, 2022, six hospitalist clinicians provided feedback on the early prototype of the GW App, and from February 28, 2023 to June 8, 2023, 30 hospitalist clinicians participated in the pilot while on clinical service. All 30 clinicians (100%) participated in the pilot submitting data for a total of 122 shifts. Participants reported working 10 ± 1 h per day (mean ± SD) and were responsible for an average of 11 ± 3 patients per day. The postpilot evaluation of the GW App showed a SUS score of 86 ± 11 and a participant preference toward mobile application-based surveys (73% of participants). Regarding workload measures, EHR event log data and notes data correlated with physician-reported workloads. Applying user-centered design techniques, we successfully developed a mobile application with high usability. These data can be paired with EHR event log data and outcomes to provide insights into the impact of workloads and work environments on outcomes.

PERSPECTIVES АND POSSIBILITIES ОF USING ARTIFICIAL INTELLIGENCE DURING AUTOGENIC TRAINING FOR PSYCHOPHYSIOLOGICAL STATE CORRECTION

The article explores the development of autogenic training for the correction of psychophysical states using artificial intelligence tools. The research aims to organise the application areas of artificial intelligence for diagnosis and correction of psychophysical states through autogenic training. The results indicate that autogenic training is an important approach in the spectrum of treatment methods for psychophysical disorders, with its main advantages being the flexibility of the technique and its ability to induce relaxation and psychophysiological self-regulation through passive concentration and repetition of specific phrases. The analysis shows that while the practice is stable and consists of sequential procedures, it can be adapted to different techniques and needs. Here, the use of artificial intelligence (AI) can significantly improve the personalisation of the treatment process and its effectiveness. The application of AI in the context of autogenic training opens up new perspectives for the diagnosis and treatment of psychophysical disorders. AI can optimise psychotherapeutic interventions by adapting training sessions to the individual needs of the user, thereby achieving better results in relaxation and psychophysical recovery. A distinctive feature of AI is also its ability to provide detailed feedback and track user progress, contributing to more effective adjustment and improvement of the training process. The integration of AI with virtual and augmented reality technologies can further enhance the autogenic training experience, creating a more immersive and controlled environment for relaxation. The development of digital tools and mobile applications based on AI has already demonstrated its positive impact on the psychophysical health of users, paving the way for more innovative and effective solutions in the future. Thus, the use of AI in autogenic training for the correction of psychophysiological states promises significant prospects for improving the quality of life and well-being of individuals.

ImageAssist: A Novel Smartphone Application for Standardized Clinical Photography That Implements and Automates American Society of Plastic Surgery/Plastic Surgery Foundation Photographic Guidelines With Background Deletion.

Standardized medical photography of the face is a vital part of patient documentation, clinical evaluation, and scholarly dissemination. Because digital photography is a mainstay in clinical care, there is a critical need for an easy-to-use mobile device application that could assist users in taking a standardized clinical photograph. ImageAssist was developed to answer this need. The mobile application is integrated into the electronic medical record (EMR); it implements and automates American Society of Plastic Surgery/Plastic Surgery Research Foundation photographic guidelines with background deletion. A team consisting of a craniofacial plastic surgeon and the Health Information Technology product group developed and implemented the pilot application of ImageAssist. The application launches directly from patients' chart in the mobile version of the EMR, EPIC Haiku (Verona, Wisconsin). Standard views of the face (90-degree, oblique left and right, front and basal view) were built into digital templates and are user selected. Red digital frames overlay the patients' face on the screen and turn green once standardized alignment is achieved, prompting the user to capture. The background is then digitally subtracted to a standard blue, and the photograph is not stored on the user's phone. ImageAssist initial beta user group was limited to 13 providers across dermatology, ENT, and plastic surgery. A mix of physicians, advanced practice providers, and nurses was included to pilot the application in the outpatient clinic setting using Image Assist on their smart phone. After using the app, an internal survey was used to gain feedback on the user experience. In the first 2 years of use, 31 users have taken more than 3400 photographs in more than 800 clinical encounters. Since initial release, automated background deletion also has been functional for any anatomic area. ImageAssist is a novel smartphone application that standardizes clinical photography and integrated into the EMR, which could save both time and expense for clinicians seeking to take consistent clinical images. Future steps include continued refinement of current image capture functionality and development of a stand-alone mobile device application.

“I can't cry on cue”: Exploring distress experiences of persons with sickle cell

Persons with sickle cell disease exhibit high levels of distress, which has been documented with validated measures. However, there has been little qualitative investigation of the sources of distress in the lives of persons with sickle cell or the strategies they use to manage different sources of distress. Our study sought to: (1) identify sources of distress for persons with sickle cell, (2) explore management strategies for different sources of distress, (3) inform content development of the future mobile phone application, and (4) incorporate patient voices in the design and development phases of the future mobile phone application. In this manuscript, we present findings for the first objective. Using convenience sampling, we recruited participants with sickle cell (n = 11) from a home visit program at The Ohio State University Wexner Medical Center between February and July 2021. One team member conducted one-on-one semi-structured interviews with participants. We coded and analyzed all transcripts. Participants identified clinical encounters in the emergency department and intermediate care center to manage acute pain flares as the most profound source of distress. Our analysis identified four themes: (1) Pain has performative features, (2) Stigma and racism surround care, (3) Sickle cell is a neglected disease, and (4) Participants lack control over their pain management plan. Researchers may wish to consider how these settings can foster distress, and providers may wish to adopt participant recommendations to reduce distress associated with seeking pain treatment in acute care settings.

A Fuzzy AHP Approach to Evaluating the Fuzzy Weight of Mobile Game Application Software Quality Factors: Usability Expectations for Novice Users

Mobile games have become a popular way to pass the time, and an increasing number of new and inexperienced users are searching for enjoyable and simple-to-learn experiences. It is essential to ensure that the software of these mobile games is intuitive and of high quality in order to keep users satisfied and coming back. However, it is difficult to assess the subjective and frequently nebulous expectations of first-time users. In between the development of mobile game applications, stakeholders in the mobile game industry are continually exploring applications whose quality is measured. The deployment of this effort will be facilitated by the quantification of qualitative aspects that depend on software quality factors. Thus, it is crucial to choose the proper evaluation strategy. The evaluation is based on two parameters: fuzzy rate and fuzzy weight. The evaluation of a five-point fuzzy rating system is based on surveys or questionnaires, and it involves straightforward inputs. Fuzzy weight refers to the relative significance of software quality aspects, and it is determined by stakeholders responsible to ensure appropriate quality of mobile application, ensuring that the crisp sum is equal to one. This may be achieved when stakeholders agree on the relative significance or pairwise comparison of software quality factors and examine their relative value. This technique guarantees that the total assessment of quality converges in the correct direction. This paper presents a novel application of the Fuzzy Analytic Hierarchy Process (FAHP) that evaluates the appropriate fuzzy weight for software quality factors of mobile game applications, particularly for neophyte users. This will aid the mobile game application industry in formulating and evaluating fuzzy weights to reinforce the process that converts qualitative to quantitative aspects during mobile application development.

UIGuider: Detecting Implicit Design Guidelines Using a Domain Knowledge Graph Approach

Mobile application developers must adhere to a set of design guidelines to ensure consistency in graphical user interfaces (GUIs) and strive for best practices. Violating these widely accepted design guidelines can negatively impact user experience and diminish an application’s market value. Although a few explicit design guidelines outline specific user interface layouts to avoid, substantial design knowledge remains scattered across various web pages. This implicit design knowledge includes design guidelines for UI component usage scenarios, anatomy, fine-grained categorizations, etc. Manually inspecting design guideline violations is knowledge-intensive and time-consuming, demanding high levels of expertise. To address this, we propose UIGuider, a novel approach to automatically constructing a component-based design knowledge graph using multimodal data. UIGuider can discern valuable text containing design guidelines, extract component and concept entities, and establish relationships among them. Our experiments demonstrate the effectiveness and usefulness of UIGuider in automatically detecting implicit design guidelines and constructing domain knowledge graphs. Additionally, the result presentation of a design violation detection tool is optimized. The results of user studies confirm that the use of the knowledge graph and real-world app datasets enhances the overall usability of the tool.

How project knowledge management develops volatile organizational memory

PurposeThis paper discusses the effects of enabling conditions of project knowledge management in building volatile organizational memory. The theoretical rationale underlies a recursive relationship among enabling conditions of project knowledge management, organizational learning and memory.Design/methodology/approachThis research employs a qualitative descriptive single case study approach to examine a mobile application development project undertaken by a major software company in Brazil. The analysis focuses on the project execution using an abductive analytical framework. The study data were collected through in-depth interviews and company documents.FindingsBased on the research findings, the factors that facilitate behavior and strategy in managing project knowledge pose a challenge when it comes to fostering organizational learning. While both these factors play a role in organizational learning, the exchange of information from previous experience could be strengthened, and the feedback from the learning process could be improved. These shortcomings arise from emotional tensions that stem from power struggles within knowledge hierarchies.Practical implicationsBased on the research, it is recommended that project-structured organizations should prioritize an individual’s professional experience to promote organizational learning. Organizations with well-defined connections between their projects and strategies can better establish interconnections among knowledge creation, sharing and coding.Originality/valueThe primary contribution is to provide a comprehensive view that incorporates the conditions required to manage project knowledge, organizational learning and memory. The findings lead to four propositions that relate to volatile memory, intuitive knowledge, learning and knowledge encoding.
