ObjectivesTo assess the current state of the art and the contribution of Free/Libre Open Source Software in health care (FLOSS-HC).MethodsThe review is based on a narrative review of the scientific literature as well as sources in the context of FLOSS-HC available through the Internet. All relevant available sources have been integrated into the MedFLOSS database and are freely available to the community.ResultsThe literature review reveals that publications about FLOSS-HC are scarce. The largest part of information about FLOSS-HC is available on dedicated websites and not in the academic literature. There are currently FLOSS alternatives available for nearly every specialty in health care. Maturity and quality varies considerably and there is little information available on the percentage of systems that are actually used in health care delivery.ConclusionsThe global impact of FLOSS-HC is still very limited and no figures on the penetration and usage of FLOSS-HC are available. However, there has been a considerable growth in the last 5 to 10 years. While there where only few systems available a decade ago, in the meantime many systems got available (e.g., more than 300 in the MedFLOSS database). While FLOSS concepts play an important role in most IT related sectors (e.g., telecommunications, embedded devices) the healthcare industry is lagging behind this trend.

Introduction: Diabetes requires a high level of disease management to be executed by the patient himself in order to succeed in treatment and for improving or at least preserving his health status. Aim: The main objective of the presented project is to design and implement a web technology based application framework. It shall provide sufficient means for selfmanagement and enable patient empowerment within the treatment process. Its underlying concept will be outlined in this work. Methods: Common techniques on requirements' engineering have been applied to derive an initial concept. It is based on a comprehensive state of the art analysis drawn from literature and web search.Results: A service-oriented architecture could be drafted that enables interoperability with existing eHealth systems on a technical and semantic level. Pilots will be deployed in Germany and Turkey. Pilot specific requirements can be address as well due to its modular architecture. Conclusion: The given concept gives a high level description of the envisaged approach. An initial prototype has been implemented. A second prototype is well on the way offering all major functionality and will be deployed within the pilot regions.

SummaryTo analyze the contribution of Free/Libre Open Source Software in health care (FLOSS-HC) and to give perspectives for future developments.The paper summarizes FLOSS-related trends in health care as anticipated by members of the IMIA Open Source Working Group. Data were obtained through literature review and personal experience and observations of the authors in the last two decades. A status quo is given by a frequency analysis of the database of Medfloss.org, one of the world’s largest platforms dedicated to FLOSS-HC. The authors discuss current problems in the field of health care and finally give a prospective roadmap, a projection of the potential influences of FLOSS in health care.FLOSS-HC already exists for more than 2 decades. Several projects have shown that FLOSS may produce highly competitive alternatives to proprietary solutions that are at least equivalent in usability and have a better total cost of ownership ratio. The Medfloss.org database currently lists 221 projects of diverse application types.FLOSS principles hold a great potential for addressing several of the most critical problems in health care IT. The authors argue that an ecosystem perspective is relevant and that FLOSS principles are best suited to create health IT systems that are able to evolve over time as medical knowledge, technologies, insights, workflows etc. continuously change. All these factors that inherently influence the development of health IT systems are changing at an ever growing pace. Traditional models of software engineering are not able to follow these changes and provide up-to-date systems for an acceptable cost/value ratio. To allow FLOSS to positively influence Health IT in the future a "FLOSS-friendly" environment has to be provided. Policy makers should resolve uncertainties in the legal framework that disfavor FLOSS. Certification procedures should be specified in a way that they do not raise additional barriers for FLOSS.

SummaryObjectives: To assess and analyze the attitude of health IT executives towards the utilization of specialized medical Open Source software (OSS) in Germany's and other European countries' health care delivery. Methods: After an initial literature review a field study was carried out based on semi-structured expert interviews. Eight German and 11 other European health IT executives were surveyed. The results were qualitatively analyzed using the grounded theory approach. Identified concepts were reviewed using SWOT analysis. Results: In total, 13 strengths, 11 weaknesses, 3 opportunities, and 8 threats of the utilization of OSS in a clinical setting could be identified. Additionally, closely related aspects like general software procurement criteria, the overall attitude of health IT executives, users, and management towards OSS and its current and future use could as well be assessed. Conclusions: Medical OSS is rarely used in health care delivery. In order to capitalize the unique advantages of OSS in a clinical setting, complex requirements need to be addressed. Shortcomings of OSS describe an attractive breeding ground for new commercial offerings and services that need yet to be seen.
