Abstract
Demographic and clinical indicators have been described to support identification of coccidioidomycosis; however, the interplay of these conditions has not been explored in a clinical setting. In 2019, we enrolled 392 participants in a cross-sectional study for suspected coccidioidomycosis in emergency departments and inpatient units in Coccidioides-endemic regions. We aimed to develop a predictive model among participants with suspected coccidioidomycosis. We applied a least absolute shrinkage and selection operator to specific coccidioidomycosis predictors and developed univariable and multivariable logistic regression models. Univariable models identified elevated eosinophil count as a statistically significant predictive feature of coccidioidomycosis in both inpatient and outpatient settings. Our multivariable outpatient model also identified rash (adjusted odds ratio 9.74 [95% CI 1.03–92.24]; p = 0.047) as a predictor. Our results suggest preliminary support for developing a coccidioidomycosis prediction model for use in clinical settings.

Abstract
BACKGROUND Coccidioidomycosis (CM) is a common cause of community acquired pneumonia (CAP) where CM is endemic. Manifestations include self-limited pulmonary infection, chronic fibrocavitary pulmonary disease, and disseminated coccidioidomycosis (DCM). Most infections are identified by serological assays including enzyme-linked immunoassay (EIA), complement fixation (CF) and immunodiffusion (IMDF). These are time-consuming and take days to result, impeding early diagnosis. A new lateral flow assay (LFA, Sōna, IMMY, Norman OK) improves time-to-result to one hour. METHODS We prospectively enrolled 392 suspected CM patients, compared the LFA to standard EIA and included procalcitonin evaluation. RESULTS Compared to standard EIA, LFA demonstrates 31% sensitivity (95% CI of 20%-44%) and 92% specificity (95% CI of 88%-95%). Acute pulmonary disease (74%) was the most common clinical syndrome. Hospitalized patients constituted 75% of subjects, and compared to outpatients, they more frequently had ≥ 3 previous healthcare facility visits (p = 0.05), received antibacterials (p & 0.01) and had > 3 antibacterial courses (p & 0.01). Procalcitonin (PCT) was &0.25 ng/ml in 52 (83%) EIA+ patients, suggesting infection was not bacterial. CONCLUSIONS When CM is a possible diagnosis, LFA identified nearly a third of EIA+ infections. Combined with PCT &0.25 ng/ml, LFA could reduce unnecessary antibacterial use by 77%.

Abstract
BACKGROUND Recognising the limitations of a paper-based approach to documenting vital sign observations and responding to national clinical guidelines, we have explored the use of an electronic solution that could improve the quality and safety of patient care. We have developed a system for recording vital sign observations at the bedside, automatically calculating an Early Warning Score, and saving data such that it is accessible to all relevant clinicians within a hospital trust. We have studied current clinical practice of using paper observation charts, and attempted to streamline the process. We describe our user-focussed design process, and present the key design decisions prior to describing the system in greater detail. RESULTS The system has been deployed in three pilot clinical areas over a period of 9 months. During this time, vital sign observations were recorded electronically using our system. Analysis of the number of observations recorded (21,316 observations) and the number of active users (111 users) confirmed that the system is being used for routine clinical observations. Feedback from clinical end-users was collected to assess user acceptance of the system. This resulted in a System Usability Scale score of 77.8, indicating high user acceptability. CONCLUSIONS Our system has been successfully piloted, and is in the process of full implementation throughout adult inpatient clinical areas in the Oxford University Hospitals. Whilst our results demonstrate qualitative acceptance of the system, its quantitative effect on clinical care is yet to be evaluated.

Abstract
To capitalize on the vast potential of patient genetic information to aid in assuring drug safety, a substantial effort is needed in both the training of healthcare professionals and the operational enablement of clinical environments. Our research aims to satisfy these needs through the development of a drug safety assurance information system (GeneScription) based on clinical genotyping that utilizes patient-specific genetic information to predict and prevent adverse drug responses. In this paper, we present the motivations for this work, the algorithms at the heart of GeneScription, and a discussion of our system and its uses. We also describe our efforts to validate GeneScription through its evaluation by practicing pharmacists and pharmacy professors and its repeated use in training pharmacists. The positive assessment of the GeneScription software tool by these domain experts provides strong validation of the importance, accuracy, and effectiveness of GeneScription.

Abstract
This paper discusses aspects of information technologies for health care, in particular on transinstitutional health information systems (HIS) and on health-enabling technologies, with some consequences for the aim of medical informatics. It is argued that with the extended range of health information systems and the perspective of having adequate transinstitutional HIS architectures, a substantial contribution can be made to better patient-centered care, with possibilities ranging from regional, national to even global care. It is also argued that in applying health-enabling technologies, using ubiquitous, pervasive computing environments and ambient intelligence approaches, we can expect that in addition care will become more specific and tailored for the individual, and that we can achieve better personalized care. In developing health care systems towards transinstitutional HIS and health-enabling technologies, the aim of medical informatics, to contribute to the progress of the sciences and to high-quality, efficient, and affordable health care that does justice to the individual and to society, may be extended to also contributing to self-determined and self-sufficient (autonomous) life. Reference is made and examples are given from the Yearbook of Medical Informatics of the International Medical Informatics Association (IMIA) and from the work of Professor Jochen Moehr.

Abstract
In 1984, Peter Reichertz gave a lecture on the past, present and future of hospital information systems. In the meantime, there has been a tremendous progress in medicine as well as in informatics. One important benefit of this progress is that our life expectancy is nowadays significantly higher than it would have been even some few decades ago. This progress, leading to aging societies, is of influence to the organization of health care and to the future development of its information systems. Twenty years later, referring to Peter Reichertz' lecture, but now considering health information systems (HIS), two questions are discussed: which were lines of development in health information systems from the past until today? What are consequences for health information systems in the future? The following lines of development for HIS were considered as important: (1) the shift from paper-based to computer-based processing and storage, as well as the increase of data in health care settings; (2) the shift from institution-centered departmental and, later, hospital information systems towards regional and global HIS; (3) the inclusion of patients and health consumers as HIS users, besides health care professionals and administrators; (4) the use of HIS data not only for patient care and administrative purposes, but also for health care planning as well as clinical and epidemiological research; (5) the shift from focusing mainly on technical HIS problems to those of change management as well as of strategic information management; (6) the shift from mainly alpha-numeric data in HIS to images and now also to data on the molecular level; (7) the steady increase of new technologies to be included, now starting to include ubiquitous computing environments and sensor-based technologies for health monitoring. As consequences for HIS in the future, first the need for institutional and (inter-) national HIS-strategies is seen, second the need to explore new (transinstitutional) HIS architectural styles, third the need for education in health informatics and/or biomedical informatics, including appropriate knowledge and skills on HIS. As these new HIS are urgently needed for reorganizing health care in an aging society, as last consequence the need for research around HIS is seen. Research should include the development and investigation of appropriate transinstitutional information system architectures, of adequate methods for strategic information management, of methods for modeling and evaluating HIS, the development and investigation of comprehensive electronic patient records, providing appropriate access for health care professionals as well as for patients, in the broad sense as described here, e.g. including home care and health monitoring facilities. Comparing the world in 1984 and in 2004, we have to recognize that we imperceptibly, stepwise arrived at a new world. HIS have become one of the most challenging and promising fields of research, education and practice for medical informatics, with significant benefits to medicine and health care in general.

Abstract
OBJECTIVES In Austria, the general practitioner (GP) is the first point of contact for persons with health problems. Depending on the severity of the person's medical condition, a GP may refer her or him to a secondary care hospital consultant, who reports findings back to the GP in form of a paper-based discharge letter. Researchers report that paper-based communication of medical documents between different health care providers is insufficient in quality, error prone and too slow in many cases. Our aim was to develop and to realise a strategy for a stepwise replacement of the paper-based transmission of medical documents with a distributed, shared medical record. METHODS In the first step of a three-steps strategy for development of a consistent, comprehensive and secure regional health care network, an electronic communication of discharge letters and diagnostic results between existing information systems of different health care providers in Tyrol, Austria, has been established: in the form of cryptographically signed S/MIME e-mail messages and, additionally, via a secure web portal system. In two further steps, an extension of the system by a bi-directional communication and by improvements of the web portal system is planned, leading to a comprehensive electronic patient record for shared care. RESULTS After realisation of step 1, in October 2004, about 3500 electronic discharge letters were sent out from the Innsbruck University Hospital (IUH), which represents about 8% of the total number of discharge letters of the IUH. In addition, a lot of feedback was received and legal, organisational, financial and methodical difficulties were overcome. DISCUSSION The stepwise approach to replace paper-based with electronic communication in the first step was helpful, since knowledge has been gained and cooperations were formed. For the realisation of a distributed, shared medical record (steps 2 and 3), it will not be sufficient only to replace paper-based transmission of medical documents with electronic communication technologies, but in the further steps, organisational changes will become necessary. As well, legal ambiguities must be resolved before a distributed medical record for cooperative care, used by several institutions as well as by patients, could be established.
