This is a matter of concern because 43% of the United States population is functionally illiterate. To empower everyone to be a full participant in the evolving health system and prevent further disparities, we must understand the design needs of low literacy populations. In this paper, we present two complementary studies of four graphical user interface (GUI) widgets and three different cross-page navigation styles in mobile applications with a varying literacy, chronically-ill population. Participant's navigation and interaction styles were documented while they performed search tasks using high fidelity prototypes running on a mobile device. Results indicate that participants could use any non-text based GUI widgets. For navigation structures, users performed best when navigating a linear structure, but preferred the features of cross-linked navigation. Based on these findings, we provide some recommendations for designing accessible mobile applications for varying-literacy populations.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

Unsurprisingly, the impact of social media has extended to the health care domain, as consumers have begun to share healthrelated experiences and knowledge online [4]. Currently, about one-third of Americans who go online to research their health use social networks to find fellow patients and discuss their conditions [1], and 36% of social network users evaluate and leverage other consumers’ knowledge before making healthcare decisions, such as choosing providers, determining a course of treatment, and managing their health risks [3].

Existing CDS tools commonly rely on relatively simple rules, deduced from relevant clinical guidelines. However, the increasing pace by which Health Care Organizations (HCOs) adopt Electronic Health Record technologies suggest great potential for CDS tools that directly mine the massive clinical data collected at the HCO. A natural goal for such tools is to exploit Machine Learning (ML) algorithms in order to predict patient's outcome. However, the technical challenges involved in constructing such a system in practice are quite involved, where in particular treatments outcome are often not available as part of the HCO's data.\u0000 Here, we propose a different strategy in which we use the assigned treatments as the labels in the learning process of the supervised ML algorithms. We present two different use-cases in which our approach could be used. First, in order to highlight the clinical features most associated with the assigned treatments; and second, in order to predict the customary treatment for a patient at POC in a statistically data-driven manner. Altogether, our approach represents a novel strategy that is complementary to the classical paradigm of rule-based clinical guidelines adherence. Experimental results over hypertension clinical data demonstrate the validity of our approach.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

National Asthma Education and Prevention Program (NAEPP) Guidelines recommend a multimodal chronic care approach. However, both of the 1997 and 2007 NAEPP guidelines have not been widely adopted by primary care clinicians because implementing the guidelines in primary care setting requires changes and redesign in clinical practice and the use of Health Information Technology (HIT) to facilitate the changes. Existing electronic asthma care systems are either inefficient to be used in real clinical encounter or provide only after-fact feedback. This paper introduces a web-based clinical decision support system that integrates intelligent computer technology, complex guideline guidance and knowledge necessary for operationalizing guidelines to improve decision making for asthma care. This system is capable of collecting guideline-suggested diagnostic measures, automatically assessing asthmatic severity and control categories based on collected measures as well as providing guideline-appropriate medication regimen. The system is implemented in a model-view-controller principle with three tiers: web-server, core reasoning algorithms and back-end database. We develop the system in conjunction with University of Connecticut Health Center to enable preliminary evaluation of the decision support system and to design an efficient and user-friendly interface that requires minimum changes in the clinical routine for primary care physicians to adapt to the system when deployed into clinical settings.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

Lexical resources, such as polarized lexicons, are needed for this task. Opinion mining in the medical domain has not been well explored, partly because little credence is given to patients and their opinions (although more and more of them are using social media). We are interested in opinion mining of user-generated content on drugs/medication. We present in this paper the creation of our lexical resources and their adaptation to the medical domain. We first describe the creation of a general lexicon, containing opinion words from the general domain and their polarity. Then we present the creation of a medical opinion lexicon, based on a corpus of drug reviews. We show that some words have a different polarity in the general domain and in the medical one. Some words considered generally as neutral are opinionated in medical texts. We finally evaluate the lexicons and show with a simple algorithm that using our general lexicon gives better results than other well-known ones on our corpus and that adding the domain lexicon improves them as well.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

Patient care teams increasingly rely upon various systems, such as Electronic Medical Records (EMRs), to support collaborative information seeking across hierarchical, functional and occupational boundaries of the organization in order to enhance the quality of medical care. However, despite their proven benefits, there still are several challenges to using EMRs for CIS, in specific, and for collaborative work, in general. The objective of this research study, therefore, is to identify some of the barriers associated with using EMRs during CIS activities. We employed qualitative research methods to understand how individuals within patient care teams use EMRs during CIS and what challenges they confront in the process. We conducted this study in the Emergency Department of a 500-bed teaching hospital. We used non-participant observations and semi-structured interviews of patient care team members for collecting our data and for capturing the practices. Through our data analysis, we identified a set of barriers to using EMRs during CIS. These include a) clash of \"technological frames\", b) lack of collective affordances, c) fear of deviations and d) alert fatigues. From the findings of our study, we highlight implications for designing EMR systems that could augment and facilitate better CIS.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

In studies using FCM data from multiple patients at multiple times, difficulties are compounded. We demonstrate IFC Soft, a program that uses Self-Organizing Maps (SOMs) to visually analyze and compare FCM data. Taking pre-processed FCM data from a transplant study, we show how to use SOMs to select clusters of cells and then to find trends among different classes of patients.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

Health illustrations and photos are essential for patient education and self-care. Currently there is few effort in automatically building comprehensive image bases for general health information consumers. We present an approach to automatically construct a consumer-oriented image library containing images of human organs, diseases, drugs and other medical entities. Such an image library can then be annotated with standard medical ontologies such as the FMA [26] and RxNorm [20], creating a rich information resource for illustration and educational purposes. As a first step in constructing such an image library, we present a semi-supervised bootstrapping classification method to retrieve relevant images from the web for given medical terms. Our method uses one positive image (for each term) as a seed and iteratively searches for images that are visually similar to the seed. We have conducted experiments in classifying web images for seven organs, four diseases and four drug tablets. We achieved average precisions of 62.4% and 66.8% for organ and drug images, which are comparable to those of a supervised classification method based on standard support vector machine (SVM) (precisions of 59.5% and 56.7%), while requiring minimum human intervention.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...

Due to the traceability of all the information, a hospital cannot function without its information system. Furthermore, if it is extended into electronic healthcare records, it may not be a dream for each patient to benefit from their personal database with all the healthcare information. Recent advances in data mining will support this trend: analysis of such large scale databases enable us to visualize and capture what we have not seen only from clinical sites. However, it is notable that conventional computerized data are described by medical staff or measured by various kinds of medical instruments. They can be viewed as summaries of clinical processes, which remove background information behind the observations. Thus, analysis based on these data cannot overcome their limitations. One of the reasons why data mining is not successful for medical risk is that it takes a long time even for medical staff to interpret the results obtained and fill the gap between their knowledge and extracted patterns.\u0000 If we want to go beyond these summaries and to get more information in order to capture the whole clinical actions or patients' behavior, we have to monitor and store their details through more sophisticated methods, such as sensor networks. For example, if we want to prevent medical incidents, in-hospital infections we have to monitor the behavior of medical staff, and if we want to prevent chronic diseases (metabolic syndromes) in an efficient way, we have to monitor the measurements of behavior of patients. Thus, although \"On data\" approaches are important for future medicine and healthcare, Ones of \"Towards data\" are more important for IT-oriented future development of these fields, which has been proposed by the organizer [1]. These data collection and their analysis will be new challenges for healthcare IT and thanks to the recent developments of sensors and devices: it will not be a dream or science fiction.\u0000 This panel gives recent advances in IT technology for data collection, their problems and their future vision: not only hardware-based or sensor-based, but also human-oriented, or human-agent-interaction based will be discussed by the panelists who play important roles in building up these fields.","PeriodicalId":90523,"journal":{"name":"IHI ... : proceedings of the ...
