Using of Raspberry Pi for data acquisition from biochemical analyzers

A large number of analyses performed in a biochemical laboratory requires that results of these analyses are automatically acquired from analyzers which can be of different types and produced by various producers. Automatic data acquisition prevents errors which are possible if results are manually transcribed into reports for patients. Beside this, acquired results are saved in database from where they are available to be used in electronic health record (EHR). Above requirement resulted in development of a solution for data acquisition from heterogeneous laboratory analyzers. Here we present the solution which is based on minicomputer Raspberry Pi model B, Raspbian OS, Mono Framework and a .NET Framework 4.0 console application written in C# programming language. Proposed solution is tightly connected with medical information system MEDIS.NET and with laboratory information system LabIS. In order to test whole concept we developed a laboratory simulator which completely implements protocol for biochemical analyzers. The emphasis is on an inexpensive solution which connects a large number of heterogeneous analyzers at a biochemical laboratory.

A software model of mobile notification system for medication misuse prevention

The one of the most common problems affecting older patients is the misuse of prescribed therapies. The patients, in many cases, forget to take their therapy, use it twice or even use the wrong medication. Since all of the mentioned cases can trigger further serious health problems, and since the majority of the population in Serbia already uses mobile phones, we decided to extend our existing medical information system with a prescription service that will allow the development of mobile-device based notification system. The notification system will then help patients with medication timing and dosing issues to take their therapies more accurate and to prevent possible health complications. In this paper we present the existing mobile services offered by the medical information system Medis.NET, as well as an architectural solution for the extension of the existing software with a prescription and notification service. The architectural solution is followed by the example of an initial implementation, description of the most important use-cases and related test results. In a near future, we plan to improve the proposed solution by offering new options to the patients, easing the connection with third party services and by developing a smartphone application that can improve the complete interaction with patients.

ON THE CHARACTERIZATION OF TASKS MODELED BY INTERVAL DESIGN STRUCTURE MATRIX ON DOMAIN-DRIVEN DESIGN SOFTWARE DEVELOPMENT

Development and design of new products of various kinds often contain a very complex set of relationships among many coupled tasks. Ranking, controlling and redesigning the features of these tasks can be usefully performed by a suitable model based on the design structure matrix in an iteration procedure. The proposed interval approach of design iteration controls and predicts the convergence speed of iteration work on tasks within a project. Interval method is based on Perron-Frobenius theorem and interval linear algebra where intervals and interval matrices are employed instead of real numbers and real matrices. In this way, a more relaxed quantitative estimation of tasks is achieved and the presence of undetermined quantities is allowed to a certain extent. The presented model is demonstrated in the example of simplified domain-driven design process, an approach to software development.

Adaption of medical information system's e-learning extension to a simple suggestion tool

Developing suggestion tools in the scope of health information systems can be a complex task, followed by a risk of not being accepted by the end users. Thus, we decide to start the implementation around the existing functionality. In this paper we present a case study showing the adaptation of e-learning medical information system extension to a set of simple suggestion tools. While some features of initial system had to be modified, the domain specific knowledge collected for the e-learning extension is used to suppress potential errors. Presented suggestion tool is based on highly configurable lists of pre-defined entities that can be easily selected, and after the verification from the medical practitioner, copied into an active visit. After four years of active use, and several iteration of update, described suggestion tools are mostly accepted among the general practitioners, especially within certain scenarios where faster medication prescription is a must.

Health Care Domain Mobile Reminder for Taking Prescribed Medications

Nowadays, majority of people as a main problem for their poor health and bad psycho-physical condition states the lack of time. Commitments, dynamic and stressful way of life lead to people being negligent of themselves. Thus, their health condition is damaged. The big problem are acute patients, but also the patients who have a chronic disease and who should take prescribed medications regularly, and who, for some reason, are prevented or have forgotten to take the prescribed dosage of the medicaments. Due to the inadequate taking of the therapy, the time for patient’s recovery is significantly prolonged or the existing problem is not relieved (with chronic patients). PersonalMedicationReminder is an Android application that downloads the prescriptions from the server of a health care institution or allows the user to insert the over-the-counter drugs (without prescription therapy). The application allows patients to create reminders and receive notifications which would inform them about the time for the next receiving of the therapy. The application downloads the prescriptions from the electronic medical record of the patient from the medical information system MEDIS.NET which is used in health institutions for primary health care in Republic of Serbia [1, 2]. The problems that occurred during the application development are also shown in the paper. In the conclusion are stated the directions of the further research and improvement of the mobile application.

Software module for registering provided health services and consumed medications in infirmary

In this paper, the software module for recording health services provided and consumed medications in the infirmary is shown. The presented software module provides software support for medical staff in the hospital, enabling the billing of health services provided to patients who are hospitalized in infirmary at the health center. Also, the software module allows monitoring and recording of consumed drugs and medical supplies (medicaments), generating e-invoices, as well as generating a larger number of fixed reports. The presented module can function as a standalone desktop application or in conjunction with medical information system (MIS) MEDIS.NET. In addition to possible horizontal integration with MIS MEDIS.NET and system for dynamically generating reports there is vertical integration with RFZO unit via electronic invoices, by checking patients insurance and loading codebooks for secondary care provided by RFZO. Presented software module currently is in used in several health care institutions and it is in closely associated with the MIS MEDIS.NET.

Software module for medications management and its integration with MIS

Modern business of health institution means the use of modern medical information system (MIS). The modern MIS must to enable the detailed monitoring of medications consumed. In order to obtain a realistic picture of consumed medications and medications in a warehouse of healthcare facilities, it is necessary to develop a special module for the management of medications and integrated the same with the module for invoicing services within the MIS. This paper shows software module for the management of medications as well as its integration with MIS MEDIS.NET. This paper shows the ability to generate dynamic reports via business intelligence tools Pentaho in order to detailed monitoring of expenditure of medications and adequate reporting management of health institutions on the basis of data collected using the module of management of medications and invoicing modules for delivery of health services.

Software support for archiving medical documents to digital form as a part of the medical information system MEDIS.NET

This paper shows solution for problem of digitalization and archiving paper documents. Implementation and integration is also shown in the medical information system (MIS) MEDIS.NET. The solution is implemented as a client/server application and it consists of two parts: digitization and archiving. The digitalization section provides saving of paper document in digital data format, while the archiving section provides storage for archiving digital data. The system can be used as an independent system or as a part of a complex system such as medical information system, in our case, MIS MEDIS.NET.
