Blockchain is a shared distributed digital ledger technology that can better facilitate data management, provenance and security, and has the potential to transform healthcare. Importantly, ...blockchain represents a data architecture, whose application goes far beyond Bitcoin - the cryptocurrency that relies on blockchain and has popularized the technology. In the health sector, blockchain is being aggressively explored by various stakeholders to optimize business processes, lower costs, improve patient outcomes, enhance compliance, and enable better use of healthcare-related data. However, critical in assessing whether blockchain can fulfill the hype of a technology characterized as 'revolutionary' and 'disruptive', is the need to ensure that blockchain design elements consider actual healthcare needs from the diverse perspectives of consumers, patients, providers, and regulators. In addition, answering the real needs of healthcare stakeholders, blockchain approaches must also be responsive to the unique challenges faced in healthcare compared to other sectors of the economy. In this sense, ensuring that a health blockchain is 'fit-for-purpose' is pivotal. This concept forms the basis for this article, where we share views from a multidisciplinary group of practitioners at the forefront of blockchain conceptualization, development, and deployment.
•Quality of care, access, consent, and privacy have been the primary telemedicine ELSI concerns.•The pandemic illuminated additional issues and informatics needs.•All these issues also apply to ...health information technologies in general.•The scope of issues needs expanding; clinicians and organizations need updated ELSI guidelines.•Evaluation that includes ELSI is necessary for decisions about health information technology.
Information technologies have been vital during the COVID-19 pandemic. Telehealth and telemedicine services, especially, fulfilled their promise by allowing patients to receive advice and care at a distance, making it safer for all concerned. Over the preceding years, professional societies, governments, and scholars examined ethical, legal, and social issues (ELSI) related to telemedicine and telehealth. Primary concerns evident from reviewing this literature have been quality of care, access, consent, and privacy.
To identify and summarize ethical, legal, and social issues related to information technology in healthcare, as exemplified by telehealth and telemedicine. To expand on prior analyses and address gaps illuminated by the COVID-19 experience. To propose future research directions.
Literature was identified through searches, forward and backward citation chaining, and the author’s knowledge of scholars and works in the area. EU and professional organizations’ guidelines, and nineteen scholarly papers were examined and categories created to identify ethical, legal, and social issues they addressed. A synthesis matrix was developed to categorize issues addressed by each source.
A synthesis matrix was developed and issues categorized as: quality of care, consent and autonomy, access to care and technology, legal and regulatory, clinician responsibilities, patient responsibilities, changed relationships, commercialization, policy, information needs, and evaluation, with subcategories that fleshed out each category. The literature primarily addressed quality of care, access, consent, and privacy. Other identified considerations were little discussed. These and newer concerns include: usability, tailoring services to each patient, curriculum and training, implementation, commercialization, and licensing and liability. The need for interoperability, data availability, cybersecurity, and informatics infrastructure also is more apparent. These issues are applicable to other information technologies in healthcare.
Clinicians and organizations need updated guidelines for ethical use of telemedicine and telehealth care, and decision- and policy-makers need evidence to inform decisions. The variety of newly implemented telemedicine services is an on-going natural experiment presenting an unparalleled opportunity to develop an evidence-based way forward. The paper recommends evaluation using an applied ethics, context-sensitive approach that explores interactions among multiple factors and considerations. It suggests evaluation questions to investigate ethical, social, and legal issues through multi-method, sociotechnical, interpretive and ethnographic, and interactionist evaluation approaches. Such evaluation can help telehealth, and other information technologies, be integrated into healthcare ethically and effectively.
The phecode system was built upon the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) for phenome-wide association studies (PheWAS) using the electronic ...health record (EHR).
The goal of this paper was to develop and perform an initial evaluation of maps from the International Classification of Diseases, 10th Revision (ICD-10) and the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes to phecodes.
We mapped ICD-10 and ICD-10-CM codes to phecodes using a number of methods and resources, such as concept relationships and explicit mappings from the Centers for Medicare & Medicaid Services, the Unified Medical Language System, Observational Health Data Sciences and Informatics, Systematized Nomenclature of Medicine-Clinical Terms, and the National Library of Medicine. We assessed the coverage of the maps in two databases: Vanderbilt University Medical Center (VUMC) using ICD-10-CM and the UK Biobank (UKBB) using ICD-10. We assessed the fidelity of the ICD-10-CM map in comparison to the gold-standard ICD-9-CM phecode map by investigating phenotype reproducibility and conducting a PheWAS.
We mapped >75% of ICD-10 and ICD-10-CM codes to phecodes. Of the unique codes observed in the UKBB (ICD-10) and VUMC (ICD-10-CM) cohorts, >90% were mapped to phecodes. We observed 70-75% reproducibility for chronic diseases and <10% for an acute disease for phenotypes sourced from the ICD-10-CM phecode map. Using the ICD-9-CM and ICD-10-CM maps, we conducted a PheWAS with a Lipoprotein(a) genetic variant, rs10455872, which replicated two known genotype-phenotype associations with similar effect sizes: coronary atherosclerosis (ICD-9-CM: P<.001; odds ratio (OR) 1.60 95% CI 1.43-1.80 vs ICD-10-CM: P<.001; OR 1.60 95% CI 1.43-1.80) and chronic ischemic heart disease (ICD-9-CM: P<.001; OR 1.56 95% CI 1.35-1.79 vs ICD-10-CM: P<.001; OR 1.47 95% CI 1.22-1.77).
This study introduces the beta versions of ICD-10 and ICD-10-CM to phecode maps that enable researchers to leverage accumulated ICD-10 and ICD-10-CM data for PheWAS in the EHR.

Abstract Objective To reflect about medical informatics as a discipline. To suggest significant future research directions with the purpose of stimulating further discussion. Methods Exploring and ...discussing important developments in medical informatics from the past and in the present by way of examples. Reflecting on the role of IMIA, the International Medical Informatics Association, in influencing the discipline. Results Medical informatics as a discipline is still young. Today, as a cross-sectional discipline, it forms one of the bases for medicine and health care. As a consequence considerable responsibility rests on medical informatics for improving the health of people, through its contributions to high-quality, efficient health care and to innovative research in biomedicine and related health and computer sciences. Current major research fields can be grouped according to the organization, application, and evaluation of health information systems, to medical knowledge representation, and to the underlying signal and data analyses and interpretations. Yet, given the fluid nature of many of the driving forces behind progress in information processing methods and their technologies, progress in medicine and health care, and the rapidly changing needs, requirements and expectations of human societies, we can expect many changes in future medical informatics research. Future research fields might range from seamless interactivity with automated data capture and storage, via informatics diagnostics and therapeutics, to living labs with data analysis methodology, involving sensor-enhanced ambient environments. The role of IMIA, the International Medical Informatics Association, for building a cooperative, strongly connected, and research-driven medical informatics community worldwide can hardly be underestimated. Conclusions Health care continuously changes as the underlying science and practice of health are in continuous transformation. Medical informatics as a discipline is strongly affected by these changes and is in a position to be a key, active contributor in these changes.
ABSTRACT Wide-Field Calcium Images (WFCI) directly reflect neuronal excitation, but their poor frame rate could be a drawback for time series analysis. This work was aimed at exploring the diagnostic ...capability retained by a time series obtained from calcium imaging data. To that purpose, we analyzed publicly available data from 2.88 hour continuous recordings of calcium images obtained from seven mice at different wake/sleep stages. Data were obtained from the Physionet portal and were submitted to Recurrence Quantification Analysis (RQA). The association between retrosplenial and parietal areas was also assessed. Nonlinear RQA analysis allowed to identify the right retrosplenial and parietal areas as particularly sensitive to changes in sleep walking condition. Specifically, our results suggested that the RQA feature lmean decreases in non-REM sleep_1 stage as compared to waking stage. Sleep (both sleep_1 stage and REM) apparently elicits an increase in the association between retrosplenial and parietal areas. Overall, these results suggest that RQA and association analysis are appropriate to assess modifications associated to changes in brain condition, in spite of the low sampling rate of WFCI signals.
