A Data Ingestion Procedure towards a Medical Images Repository.

This article presents an ingestion procedure towards an interoperable repository called ALPACS (Anonymized Local Picture Archiving and Communication System). ALPACS provides services to clinical and hospital users, who can access the repository data through an Artificial Intelligence (AI) application called PROXIMITY. This article shows the automated procedure for data ingestion from the medical imaging provider to the ALPACS repository. The data ingestion procedure was successfully applied by the data provider (Hospital Clínico de la Universidad de Chile, HCUCH) using a pseudo-anonymization algorithm at the source, thereby ensuring that the privacy of patients' sensitive data is respected. Data transfer was carried out using international communication standards for health systems, which allows for replication of the procedure by other institutions that provide medical images. OBJECTIVES: This article aims to create a repository of 33,000 medical CT images and 33,000 diagnostic reports with international standards (HL7 HAPI FHIR, DICOM, SNOMED). This goal requires devising a data ingestion procedure that can be replicated by other provider institutions, guaranteeing data privacy by implementing a pseudo-anonymization algorithm at the source, and generating labels from annotations via NLP. METHODOLOGY: Our approach involves hybrid on-premise/cloud deployment of PACS and FHIR services, including transfer services for anonymized data to populate the repository through a structured ingestion procedure. We used NLP over the diagnostic reports to generate annotations, which were then used to train ML algorithms for content-based similar exam recovery. OUTCOMES: We successfully implemented ALPACS and PROXIMITY 2.0, ingesting almost 19,000 thorax CT exams to date along with their corresponding reports.

Design and Development of Learning Management System Huemul for Teaching Fast Healthcare Interoperability Resource: Algorithm Development and Validation Study.

BACKGROUND: Interoperability between health information systems is a fundamental requirement to guarantee the continuity of health care for the population. The Fast Healthcare Interoperability Resource (FHIR) is the standard that enables the design and development of interoperable systems with broad adoption worldwide. However, FHIR training curriculums need an easily administered web-based self-learning platform with modules to create scenarios and questions that the learner answers. This paper proposes a system for teaching FHIR that automatically evaluates the answers, providing the learner with continuous feedback and progress. OBJECTIVE: We are designing and developing a learning management system for creating, applying, deploying, and automatically assessing FHIR web-based courses. METHODS: The system requirements for teaching FHIR were collected through interviews with experts involved in academic and professional FHIR activities (universities and health institutions). The interviews were semistructured, recording and documenting each meeting. In addition, we used an ad hoc instrument to register and analyze all the needs to elicit the requirements. Finally, the information obtained was triangulated with the available evidence. This analysis was carried out with Atlas-ti software. For design purposes, the requirements were divided into functional and nonfunctional. The functional requirements were (1) a test and question manager, (2) an application programming interface (API) to orchestrate components, (3) a test evaluator that automatically evaluates the responses, and (4) a client application for students. Security and usability are essential nonfunctional requirements to design functional and secure interfaces. The software development methodology was based on the traditional spiral model. The end users of the proposed system are (1) the system administrator for all technical aspects of the server, (2) the teacher designing the courses, and (3) the students interested in learning FHIR. RESULTS: The main result described in this work is Huemul, a learning management system for training on FHIR, which includes the following components: (1) Huemul Admin: a web application to create users, tests, and questions and define scores; (2) Huemul API: module for communication between different software components (FHIR server, client, and engine); (3) Huemul Engine: component for answers evaluation to identify differences and validate the content; and (4) Huemul Client: the web application for users to show the test and questions. Huemul was successfully implemented with 416 students associated with the 10 active courses on the platform. In addition, the teachers have created 60 tests and 695 questions. Overall, the 416 students who completed their courses rated Huemul highly. CONCLUSIONS: Huemul is the first platform that allows the creation of courses, tests, and questions that enable the automatic evaluation and feedback of FHIR operations. Huemul has been implemented in multiple FHIR teaching scenarios for health care professionals. Professionals trained on FHIR with Huemul are leading successful national and international initiatives.

Interoperable Platform to Report Polymerase Chain Reaction SARS-CoV-2 Tests From Laboratories to the Chilean Government: Development and Implementation Study.

BACKGROUND: Testing, traceability, and isolation actions are a central strategy defined by the World Health Organization to contain the COVID-19 pandemic. In this sense, the countries have had difficulties in counting the number of people infected with SARS-CoV-2. Errors in reporting results are a common factor, as well as the lack of interoperability between laboratories and governments. Approaches aimed at sending spreadsheets via email expose patients' privacy and have increased the probability of errors due to retyping, which generates a delay in the notification of results. OBJECTIVE: This study aims to design and develop an interoperable platform to report polymerase chain reaction (PCR) SARS-CoV-2 tests from laboratories to the Chilean government. METHODS: The methodology to design and develop the interoperable platform was comprised of six well-structured stages: (1) creation of a minimum data set for PCR SARS-CoV-2 tests, (2) modeling processes and end points where institutions interchange information, (3) standards and interoperability design, (4) software development, (5) software testing, and (6) software implementation. RESULTS: The interoperable Fast Healthcare Interoperability Resources (FHIR) platform to report PCR SARS-CoV-2 tests from laboratories to the Chilean government was successfully implemented. The platform was designed, developed, tested, and implemented following a structured methodology. The platform's performance to 1000 requests resulted in a response time of 240 milliseconds, throughput of 28.3 requests per second, and process management time of 131 milliseconds. The security was assured through a private network exclusive to the Ministry of Health to ensure confidentiality and integrity. The authorization and authentication of laboratories were implemented with a JavaScript Object Notation Web Token. All the PCR SARS-CoV-2 tests were accessible through an application programming interface gateway with valid credentials and the right access control list. CONCLUSIONS: The platform was implemented and is currently being used by UC Christus Laboratory. The platform is secure. It was tested adequately for confidentiality, secure authorization, authentication, and message integrity. This platform simplifies the reporting of PCR SARS-CoV-2 tests and reduces the time and probability of mistakes in counting positive cases. The interoperable solution with FHIR is working successfully and is open for the community, laboratories, and any institution that needs to report PCR SARS-CoV-2 tests.

Using OPC and HL7 Standards to Incorporate an Industrial Big Data Historian in a Health IT Environment.

Health Level Seven (HL7) is one of the standards most used to centralize data from different vital sign monitoring systems. This solution significantly limits the data available for historical analysis, because it typically uses databases that are not effective in storing large volumes of data. In industry, a specific Big Data Historian, known as a Process Information Management System (PIMS), solves this problem. This work proposes the same solution to overcome the restriction on storing vital sign data. The PIMS needs a compatible communication standard to allow storing, and the one most commonly used is the OLE for Process Control (OPC). This paper presents a HL7-OPC Server that permits communication between vital sign monitoring systems with PIMS, thus allowing the storage of long historical series of vital signs. In addition, it carries out a review about local and cloud-based Big Medical Data researches, followed by an analysis of the PIMS in a Health IT Environment. Then it shows the architecture of HL7 and OPC Standards. Finally, it shows the HL7-OPC Server and a sequence of tests that proved its full operation and performance.

SOA-BD: Service Oriented Architecture for Biomedical Devices

Introduction: The communication of information systems with biomedical devices has become complex not only due to the existence of several private communication protocols, but also to the immutable way that software is embedded into these devices. In this sense, this paper proposes a service-oriented architecture to access biomedical devices as a way to abstract the mechanisms of writing and reading data from these devices, thus contributing to enable the focus of the development team of biomedical software to be intended for its functional requirements, i.e. business rules relevant to the problem domain. Methods The SOA-BD architecture consists of five main components: A Web Service for transport and conversion of the device data, Communication Protocols to access the devices, Data Parsers to preprocess data, a Device Repository to store data and transmitted information and Error handling, for error handling of these information. For the development of SOA-BD, technologies such as the XML language and the Java programming language were used. Besides, Software Engineering concepts such as Design Patterns were also used. For the validation of this work, data has been collected from vital sign monitors in an Intensive Care Unit using HL7 standards. Results The tests obtained a difference of about only 1 second in terms of response time with the use of SOA-BD. Conclusion SOA-BD achieves important results such as the reduction on the access protocol complexity, the opportunity for treating patients over long distances, allowing easier development of monitoring applications and interoperability with biomedical devices from diverse manufacturers.

Sistema de gestión de información de historia clínica electrónica en terapias alternativas / Information management system for electronic medical records in alternative therapies / Sistema de gestão de informação de história clínica electrônica em terapias alternativas

Las terapias alternativas son cada vez más utilizadas en la atención en salud. Actualmente la mayoría de las entidades de salud que prestan dichos servicios realizan el registro de estas intervenciones terapéuticas de forma manual, lo cual produce inconvenientes como: posible pérdida de información, falta de control y seguimiento del paciente, falta de interacción e interoperabilidad con la historia clínica convencional, e imposibilidad de desarrollar estudios estadísticos con información proveniente de dichos registros. El presente artículo presenta un sistema de gestión de información para una historia clínica electrónica en terapias alternativas, basado en un modelo conceptual, y un modelo de interoperabilidad basado en el estándar Health Level 7 (HL7). Para el diseño del modelo conceptual, además de la revisión bibliográfica, se desarrolló una investigación de tipo mixto, con un diseño observacional descriptivo mediante una muestra a conveniencia, conformada por siete docentes y once expertos en terapias alternativas. Se indagó acerca de las características de los instrumentos y herramientas utilizados por los expertos para la gestión de la información. Una vez finalizada la propuesta del modelo, esta fue validada por los expertos. Para el modelo de interoperabilidad se consideraron los aspectos técnicos y sintácticos al diseñar una arquitectura de servicios para el envío y recepción de mensajes. En cuanto a la interoperabilidad sintáctica, se diseñó una estructura de mensaje según HL7 con información de pacientes.

The use of alternative therapies is on the increase in health care. Most of the health institutions currently rendering such services keep manual records of therapeutic interventions, resulting in inconveniences such as the possible loss of information, lack of patient control and follow-up, lack of interaction and interoperability with conventional medical records, and inability to develop statistical studies based on data from those records. The paper presents an information management system for electronic medical records in alternative therapies based on a conceptual model and an interoperability model based on the Health Level 7 (HL7) standard. For the design of the conceptual model, in addition to the literature review, a mixed research study was conducted with a descriptive observational design using a convenience sample of seven teachers and eleven experts on alternative therapies. Participants were asked about the characteristics of the instruments and tools used by information management experts. A model proposal was developed which was validated by the experts. For the interoperability model account was taken of the technical and syntactic aspects involved in the design of a service architecture for message submission and reception. For syntactic interoperability a message structure was designed based on HL7 and patient information.

As terapias alternativas são cada vez mais utilizadas na atenção em saúde. Actualmente a maioria das entidades de saúde que emprestam ditos serviços realizam o registro destas intervenções terapéuticas de forma manual, o qual produz inconvenientes como: possível perda de informação, falta de controle e acompanhamento do paciente, falta de interacção e interoperabilidade com a história clínica convencional, e impossibilidade de desenvolver estudos estatísticos com informação proveniente de ditos registros. O presente artigo apresenta um sistema de gestão de informação para uma história clínica electrônica em terapias alternativas, baseado num modelo conceitual, e um modelo de interoperabilidade baseado no estándar Health Level 7 (HL7). Para o desenho do modelo conceitual, para além da revisão bibliográfica, desenvolveu-se uma investigação de tipo misto, com um desenho observacional descriptivo mediante uma amostra à conveniência, conformada por sete docentes e onze expertos em terapias alternativas. Indagou-se sobre as características dos instrumentos e ferramentas utilizados pelos expertos para a gestão da informação. Uma vez finda a proposta do modelo, esta foi validada pelos expertos. Para o modelo de interoperabilidade foram considerados os aspectos técnicos e sintáticos ao desenhar uma arquitetura de serviços para o envio e recepção de mensagens. Em relação à interoperabilidade sintática, foi desenhada uma estructura de mensagem segundo HL7 com informação de pacientes.

Almacenamiento externo de los datos patronímicos de un CDA / External storage of the patronymic data on a CDA

En el Uruguay el Decreto Nº 396/003 sobre Historia clínica electrónica establece que los datos patronímicos tienen que separarse de los datos clínicos salvo contexto de atención medica, el CDA es un documento que normalmente contiene ambos. Utilizamos esta especificación para registrar el documento clínico referente a la ?descripción operatoria?, restringiendo lo patronímico a un solo identificador, el cual permite encontrar los datos almacenados en otro sistema desacoplado. La conciliación del identificador con la información patronímica, se realiza mediante transacciones IHE pertenecientes al perfil PDQ de forma transparente al usuario autorizado, que edita o revisa el documento.

In Uruguay, the Decree No. 396/003 on electronic medical records states that patronymic data must be separated from clinical data except in the medical care context, the CDA is a document that typically contains both. We use this specification to record the clinical document regarding ?operative description?, restricting the patronymic information to a single identifier, which allows to find data stored on another disengaged system. Reconciliation of the identifier with the patronymic information is effected through IHE transactions belonging to the PDQ Profile which it is done transparently to the user authorized to edit or revise the document.
