The purpose of this paper is to identify and analyze some relevant issues which arise when the concept of metrological traceability is applied to health care facilities. Discussion is structured around the results that were obtained through a characterization and comparative description of the practices applied in 45 different Portuguese health entities. Following a qualitative exploratory approach, the information collected was the support for the initial research hypotheses and the development of the questionnaire survey. It was also applied a quantitative methodology that included a descriptive and inferential statistical analysis of the experimental data set. © Published under licence by IOP Publishing Ltd. Source

Medical measurements are present in the everyday life of people and are fundamental processes in prevention, diagnosis and treatment of disease. Therefore, a growing interest lies in the role of metrological decisions and conformity assessment, namely where measurements are in support of health. This paper focuses on the use of medical devices looking to enhance its metrological traceability, highlighting the specific role of metrology in the field of health care and the impact of legal control in the framework of the medical devices regulation with a measuring function. It is proposed a new regulatory approach for medical devices in use, facing the convergence between European policy enforcement and Metrological regulations. Source

To evaluate the role of metrology in healthcare facilities, a study was performed among Portuguese hospitals to identify and analyze issues concerning the concept of metrological traceability. The discussion is structured around a dataset obtained from a survey questionnaire covering 44 public and private Portuguese hospitals. The principal results of our analysis include identifying some key indicators that apply to certified/accredited hospitals. Test reports and calibration certificates were the main metrological traceability documents required by the hospitals. The acquisition of medical measuring instruments with conformity reports depended on the type of hospital. Maintenance was considered the most relevant issue for private hospitals, whereas for the public hospitals, this issue is less important than trust in the supplier. For public hospitals, purchase price was the most important requirement. For hospitals that acquire calibrated measuring instruments, only 50 % perform in-house calibration. We conclude that trust in supplier is associated with a lower overall budget for maintenance operations. The protocol established by hospitals to acquire measurement instruments does not reflect metrological concerns, and the relationship between maintenance and metrological operation is not well established. Thus, we conclude that metrological traceability is largely absent in the daily considerations of healthcare professionals and facilities. © 2015 Springer-Verlag Berlin Heidelberg Source
