Generating case notes from digital transcripts using text mining

Abstract

Current health care systems require clinicians to spend a substantial amount of time to digitally document their interactions with their patients through the use of electronic health records (EHRs), limiting the time spent on face-to-face patient care. Moreover, the use of EHRs is known to be highly inefficient due to additional time it takes for completion, which also leads to clinician burnout. In this project, we explore the feasibility of developing an automated case notes system for psychiatrists using text mining techniques that will listen to doctor-patient conversations, generate digital transcripts using speech-to-text conversion, classify information from the transcripts by identifying important keywords, and automatically generate structured case notes. In our preliminary work, we develop a human powered doctor-patient transcript annotator and obtain a gold standard dataset through National Alliance of Mental Illness (NAMI) Montana. We model the task of classifying parts of conversations in to six broad categories such as medical and family history as a supervised classification problem and apply several popular machine learning algorithms. According to our preliminary experimental results obtained through 5-fold cross validation, Support Vector Machines are able to classify an unseen transcript with an average AUROC (area under the receiver operating characteristic curve) score of 89%. Using part-of-speech (POS) tagging, grammatical rules of English language and verb conjugation, we generate formal representation of each sample. For each class, we form a paragraph using the formal representations of its samples. Using these paragraphs, we generate a case note.

Supply Chain Logistics and Business Ecosystems Needed for the Development of Natural Vaccines with Novel, Safer, and Noninvasive Delivery Mechanisms

“…In addition to vaccine development, R&D efforts focus on improving production processes and establishing protocols for large-scale manufacturing. The research team strives to develop efficient and cost-effective methods for extracting and purifying the vaccine antigens from tomato plants while maintaining their integrity and immunogenicity [12][13][14]. R&D provides the foundation for subsequent stages in the supply chain.…”

“…The challenges and opportunities presented in this chapter are intended to assist these companies in making informed decisions and building a foundation for successful vaccine development and distribution. As the world adapts to the changing landscape of infectious diseases, the pursuit of natural vaccines and innovative delivery methods holds immense promise [12][13][14]. By creating a seamless supply chain and understanding the market dynamics, vaccine companies can play a pivotal role in shaping the future of global health and disease prevention.…”

“…Following that, we will explore the process of plant cultivation and fruit growth within greenhouses, emphasizing FruitVaccine's innovative methods in this critical component. The subsequent discussion will revolve around the manufacturing of various vaccine formats and finish off by delving into the packaging and distribution segment, underscoring how FruitVaccine optimizes these processes to allow for global vaccine access and coverage [12][13][14]. This comprehensive overview will provide a clearer connection between the steps of the natural vaccine supply chain and our case study, FruitVaccine, offering valuable insights into the complexities and innovations that drive the success of this unique approach to vaccine development and distribution.…”
