The most frequent form of dementia is Alzheimer's Disease (AD), a severe progressive neurological pathology in which the main cognitive functions of an individual are compromised. Recent studies have found that loneliness and living in isolation are likely to cause an acceleration in the cognitive decline associated with AD. Therefore, understanding social behaviours of AD patients is crucial to promote sociability, thus delaying cognitive decline, preserving independence, and providing a good quality of life. In this work, we analyze the localization data of AD patients living in assisted care homes to gather insights about the social dynamics among them. We use localization data collected by a system based on iBeacon technology comprising two components: a network of antennas scattered throughout the facility and a Bluetooth bracelet worn by the patients. We redefine the Relational Index to capture wandering and casual encounters, these being common phenomena among AD patients, and use the notions of Relational and Popularity Indexes to model, visualize and understand the social behaviour of AD patients. We leverage the data analyses to build predictive tools and applications to enhance social activities scheduling and sociability monitoring and promotion, with the ultimate aim of providing patients with a better quality of life. Predictions and visualizations act as a support for caregivers in activity planning to maximize treatment effects and, hence, slow down the progression of Alzheimer's disease. We present the Community Behaviour Prediction Table (CBPT), a tool to visualize the estimated values of sociability among patients and popularity of places within a facility. Finally, we show the potential of the system by analyzing the Coronavirus Disease 2019 (COVID-19) lockdown time-frame between February and June 2020 in a specific facility. Through the use of the indexes, we evaluate the effects of the pandemic on the behaviour of the residents, observing no particular impact on sociability even though social distancing was put in place.

COVID-19 CG ( is an open resource for tracking SARS-CoV-2 single-nucleotide variations (SNVs), lineages, and clades using the virus genomes on the GISAID database while filtering by location, date, gene, and mutation of interest. COVID-19 CG provides significant time, labor, and cost-saving utility to projects on SARS-CoV-2 transmission, evolution, diagnostics, therapeutics, vaccines, and intervention tracking. Here, we describe case studies in which users can interrogate (1) SNVs in the SARS-CoV-2 spike receptor binding domain (RBD) across different geographical regions to inform the design and testing of therapeutics, (2) SNVs that may impact the sensitivity of commonly used diagnostic primers, and (3) the emergence of a dominant lineage harboring an S477N RBD mutation in Australia in 2020. To accelerate COVID-19 efforts, COVID-19 CG will be upgraded with new features for users to rapidly pinpoint mutations as the virus evolves throughout the pandemic and in response to therapeutic and public health interventions.

OBJECTIVE: Reducing risk of coronavirus disease 2019 (COVID-19) infection among healthcare personnel requires a robust occupational health response involving multiple disciplines. We describe a flexible informatics solution to enable such coordination, and we make it available as open-source software. MATERIALS AND METHODS: We developed a stand-alone application that integrates data from several sources, including electronic health record data and data captured outside the electronic health record. RESULTS: The application facilitates workflows from different hospital departments, including Occupational Health and Infection Control, and has been used extensively. As of June 2020, 4629 employees and 7768 patients and have been added for tracking by the application, and the application has been accessed over 46 000 times. DISCUSSION: Data captured by the application provides both a historical and real-time view into the operational impact of COVID-19 within the hospital, enabling aggregate and patient-level reporting to support identification of new cases, contact tracing, outbreak investigations, and employee workforce management. CONCLUSIONS: We have developed an open-source application that facilitates communication and workflow across multiple disciplines to manage hospital employees impacted by the COVID-19 pandemic.

Information management in the emergency department (ED) is a challenge for all providers. The volume of information required to care for each patient and to keep the ED functioning is immense. It must be managed through varying means of communication and in connection with ED information systems. Management of information in the ED is imperfect; different modes and methods of identification, interpretation, action, and communication can be beneficial or harmful to providers, patients, and departmental flow. This article reviews the state of information management in the ED and proposes recommendations to improve the management of information in the future.

Correct patient identification is the cornerstone for the proper implementation of electronic health records. Up to 20% of the registered patients are duplicated in most systems. Strong identification policies and robust systems can minimize such errors. In this poster we share the Ministry of Health recommendations for the Master Patient Index improvement using search algorithms.

We present a four-objective optimization method for optimal electroencephalographic (EEG) channel selection to provide access to subjects with permission in a system by detecting intruders and identifying the subject. Each instance was represented by four features computed from two sub-bands, extracted using empirical mode decomposition (EMD) for each channel, and the feature vectors were used as input for one-class/multi-class support vector machines (SVMs). We tested the method on data from the event-related potentials (ERPs) of 26 subjects and 56 channels. The optimization process was performed by the non-dominated sorting genetic algorithm (NSGA), which found a three-channel combination that achieved an accuracy of 0.83, with both a true acceptance rate (TAR) and a true rejection rate (TRR) of 1.00. In the best case, we obtained an accuracy of up to 0.98 for subject identification with a TAR of 0.95 and a TRR 0.93, all using seven EEG channels found by NSGA-III in a subset of subjects manually created. The findings were also validated using 10 different subdivisions of subjects randomly created, obtaining up to 0.97 ± 0.02 of accuracy, a TAR of 0.81 ± 0.12 and TRR of 0.85 ± 0.10 using eight channels found by NSGA-III. These results support further studies on larger datasets for potential applications of EEG in identification and authentication systems.

OBJETIVO: determinar si es correcta la identificación a través de las pulseras identificativas y de grupo sanguíneo en los pacientes intervenidos de cirugía ortopédica. MÉTODO: estudio descriptivo transversal. La población de estudio fueron los pacientes intervenidos de cirugía ortopédica de prótesis de rodilla y cadera en el Hospital Universitario de Burgos. Técnica de recogida de los datos: observación directa. Variables de estudio: sexo; edad; tipo de cirugía; lado de la cirugía; colocación de pulseras; portador de vía venosa; canalización de vía en quirófano; calibre; retirada de las pulseras; sustitución de las pulseras; tiempo sin pulseras; vía y pulsera en el mismo brazo y planta de origen. RESULTADOS: se analizaron 153 casos. El 100% de los pacientes contaba con una pulsera identificativa y el 98% tenía pulsera de grupo sanguíneo. Fue necesario retirar por colocación incorrecta el 27% de las pulseras identificativas y el 29% de las de grupo sanguíneo; todas fueron sustituidas. La media del tiempo que el paciente pasó en el quirófano sin pulsera con datos personales fue de 51,62 minutos y sin la pulsera de grupo sanguíneo de 50,36 minutos. CONCLUSIONES: la gran mayoría de los pacientes se encontraban correctamente identificados a través de las dos pulseras, aunque por necesidades de la cirugía en algunos casos debían retirarse quedando los pacientes sin identificar durante aproximadamente una hora. La comunicación e información con las enfermeras resulta fundamental para mejorar la calidad de los cuidados y la seguridad del enfermo

OBJECTIVE: to determine if there is an adequate use of identification and blood type wristbands in patients undergoing ortophedic surgery. METHOD: a cross-sectional descriptive study. The study population consisted of patients who had undergone orthopedic surgery for knee and hip prosthesis at the Hospital Universitario de Burgos. Data collection technique: direct observation. Study variables: gender, age, type of surgery, side of surgery, wristband placement, central venous line, IV line catheterization at the operating room, gauge, wristband removal, wristband replacement, time without wristbands, IV line and wristband in the same arm, and ward of origin. RESULTS: the study analyzed 153 cases; 100% of patients had an identification wristband, and 98% had blood type wristbands. It was necessary to remove 27% of the identification wristbands and 29% of the blood type wristbands due to incorrect placement; all of them were replaced. The mean time that the patient stayed at the operating room without a personal data wristband was 51.62 minutes, and 50.36 minutes without blood type wristband. CONCLUSIONS: the vast majority of patients were adequately identified through the two wristbands; though, for surgical requirements, in some cases these had to be removed, and patients were unidentified during approximately one hour. Communication and information with nurses becomes essential in order to improve the quality of care and patient safety

Waiting times are still assumed to be unavoidable in medicine. However, waiting time is an essential factor of patient satisfaction. Because patient expectations are increasing, medical institutions should address the issue. Above all, this requires transparency about the current processes in the facilities. Conventional information systems often do not offer sufficient solutions to ensure this in real time combined with helpful visualization. In a pilot project in a radiological practice, the use of a patient tracking system based on beacon technology was tested. The aim was to track the actual location of the patients in the practice, to determine the patient status (e.g. patient waiting) and to display the entire processes on a smart dashboard. The successful pilot project has shown that the technology meets all requirements, that patients accept the system and that staff are familiar with the new processes after some time. For the first time, patient flows, including waiting times, were displayed clearly and in real time on a dashboard. This made it possible to control processes and waiting times that had previously never been recorded in a structured manner and were usually only recognized in the event of complaints. From a technical point of view, the system is arbitrarily scalable, whereby the connection to different information systems will be a challenge. If this succeeds, however, the possibilities are manifold. The created transparency makes it possible to reduce waiting times and to actively inform patients about waiting times and thus contribute to increasing patient satisfaction.

CONTEXT.­: Preanalytic errors, including specimen labeling errors and specimen loss, occur frequently during specimen collection, transit, and accessioning. Radio-frequency identification tags can decrease specimen identification and tracking errors through continuous and automated tracking of specimens. OBJECTIVE.­: To implement a specimen tracking infrastructure to reduce preanalytic errors (specimen mislabeling or loss) between specimen collection and laboratory accessioning. Specific goals were to decrease preanalytic errors by at least 70% and to simultaneously decrease employee effort dedicated to resolving preanalytic errors or investigating lost specimens. DESIGN.­: A radio-frequency identification specimen-tracking system was developed. Major features included integral radio-frequency identification labels (radio-frequency identification tags and traditional bar codes in a single printed label) printed by point-of-care printers in collection suites; dispersed radio-frequency identification readers at major transit points; and systems integration of the electronic health record, laboratory information system, and radio-frequency identification tracking system to allow for computerized physician order entry driven label generation, specimen transit time tracking, interval-based alarms, and automated accessioning. RESULTS.­: In the 6-month postimplementation period, 6 mislabeling events occurred in collection areas using the radio-frequency identification system, compared with 24 events in the 6-month preimplementation period (75% decrease; P = .001). In addition, the system led to the timely recovery of 3 lost specimens. Labeling expenses were decreased substantially in the transition from high-frequency to ultrahigh frequency radio-frequency identification tags. CONCLUSIONS.­: Radio-frequency identification specimen tracking prevented several potential specimen-loss events, decreased specimen recovery time, and decreased specimen labeling errors. Increases in labeling/tracking expenses for the system were more than offset by time savings and loss avoidance through error mitigation.

OBJECTIVE: This study assesses the performance of the North American Association of Central Cancer Registries Asian/Pacific Islander Identification Algorithm (NAPIIA) to infer Hmong ethnicity. DESIGN AND SETTING: Analyses of electronic health records (EHRs) from 1 January 2011 to 1 October 2015. The NAPIIA was applied to the EHR data, and self-reported Hmong ethnicity from a questionnaire was used as the gold standard. Sensitivity, specificity, positive (PPV) and negative predictive values (NPVs) were calculated comparing the source data ethnicity inferred by the algorithm with the self-reported ethnicity from the questionnaire. PARTICIPANTS: EHRs indicating Hmong, Chinese, Vietnamese and Korean ethnicity who met the original study inclusion criteria were analysed. RESULTS: The NAPIIA had a sensitivity of 78%, a specificity of 99.9%, a PPV of 96% and an NPV of 99%. The prevalence of Hmong population in the sample was 3.9%. CONCLUSION: The high sensitivity of the NAPIIA indicates its effectiveness in detecting Hmong ethnicity. The applicability of the NAPIIA to a multitude of Asian subgroups can advance Asian health disparity research by enabling researchers to disaggregate Asian data and unmask health challenges of different Asian subgroups.
