BACKGROUND Medical errors are one of the greatest problems in any healthcare systems. The best way to prevent such problems is errors identification and their roots. Failure Mode and Effects Analysis (FMEA) technique is a prospective risk analysis method. This study is a review of risk analysis using FMEA technique in different hospital wards and departments. METHODS This paper systematically...
در این رساله با به کارگیری فرآیند fmea (failure mode and effect analysis و با نگاهی چند جانبه و علت گرا ریشه های احتمالی خرابی یک پمپ گریز از مرکز با سرویس lpg مورد بررسی و مطالعه قرار گرفته است. ابتدا با جمع آوری و بررسی آمار خرابی 368 پمپ در یک دوره هشت ساله، پمپ با بیشترین آمار خرابی به عنوان یک نمونه مطالعاتی انتخاب شد و با بررسی مستندات مربوط به فعالیت های تعمیراتی پمپ مذکور، مشخص شد که...
Functional safety analysis (FSA), that is checking whether a designed artifact will perform safely even under the presence of failing components, has gained significant importance in different areas, including aeronautic and automotive systems. The same applies to failure-modes-and-effects analysis (FMEA) and fault-tree analysis (FTA) as the major contributing processes. FSA is laborand time-co...
Background and Aim: Almost one out of 10 patients who are admitted in hospitals experience “never events” while researches show that about half of these harms are preventable through the utilization of Failure Modes and Effects Analysis (FMEA). This study aims to identify and evaluate the risks of care processes in three wards of Alzahra University Hospital of Isfahan and suggest some intervent...
From last three decades various tools, techniques and methods are developed by researchers. The objective of research is to optimize the error and improve the quality of the software. During development of software, various errors are introduced by the developer at various phases of software development life cycle (SDLC). It is difficult to identify all the errors of the software by the develop...
The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...

Aim: To develop a systematic approach to detect and prevent clinical risks in complementary medicine (CM) and increase patient safety through the analysis of activities in homeopathy and acupuncture centres in the Tuscan region using a significant event audit (SEA) and failure modes and effects analysis (FMEA). Methods: SEA is the selected tool for studying adverse events (AE) and detecting the...
Nowadays, Customers are placing tremendous pressure on vendor companies for high quality, reliable products. The rising capabilities and functionality of many products are creating it additional complex for producer to keep up the quality and reliability, which not only satisfies him but also delights him. Considerable research has been carried out and literature available in the field of Suppl...
Changes of software requirements are inevitable during the development life cycle. Rather than avoiding the circumstance, it is easier to just accept it and find a way to anticipate those changes. This paper proposes a method to analyze the volatility of requirement by using the Quality Function Deployment (QFD) method and the introduced degree of volatility. Customer requirements are deployed ...
