Risk analysis using fuzzy set theory of accidental exposure of medical staff during brachytherapy procedures

2010

Using fuzzy set theory, this paper presents results from risk analyses that explore potential exposure of medical operators working in a high dose rate brachytherapy irradiation plant. In these analyses, the HEART methodology, a first generation method for human reliability analysis, has been employed to evaluate the probability of human error. This technique has been modified on the basis of fuzzy set concepts to take into account, more directly, the uncertainties of the so-called error-promoting factors on which the method is based. Moreover, with regard to some identified accident scenarios, fuzzy potential dose was also evaluated to estimate the relevant risk. The results also provide s…

Liver failure after partial hepatic resection: definition, pathophysiology, risk factors and treatment

2008

Liver failure is a dreaded and often fatal complication that sometimes follows a partial hepatic resection. This article reviews the definition, incidence, pathogenesis, risk factors, risk assessment, prevention, clinical features and treatment of post-resectional liver failure (PLF). A systematic, computerized search was performed using key words related to 'partial hepatic resection' and 'liver failure' to review most relevant literature about PLF published in the last 20 years. The reported incidence of PLF ranges between 0.7 and 9.1%. An inadequate quantity or quality of residual liver mass are key events in its pathogenesis. Major risk factors are the presence of comorbid conditions, p…

The Soil Erosion Risk Map of the Sicilian Region (1:250,000 Scale)

2014

Assessing the risk areas of soil erosion by water at the regional level is relevant for current and future land planning of environmental actions to combat land degradation. The gravity of the risk is not only depending on the rate of soil erosion by water, but also on other factors, primarily soil depth and rock weatherability. The map of the soil erosion risk in the Sicilian region, expressed in terms of years to a complete loss of the fertile soil cover, is here presented as a methodological model. The degree of risk was not only estimated in function of the rate of soil erosion by water, but also of the depth of the fertile part of the profile, and of the weatherability degree of the un…

On Aggregation of Risk Levels Using T-Conorms

2019

This paper deals with solutions for numeric evaluation of risks containing several different risk factors assessed by experts. The proposed methods can be used to assess the risks and obtain the risk scores in different industries, including financial industry, but they are also suitable for assessing risks in other areas, e.g. project management. While risk is usually considered as a function of probability and impact with strong quantitative background, there are many practical cases when only qualitative risk assessment based on expert opinions can be used. At the same time there are still requirements and needs for applying numerical values and mathematical models to such qualitative as…

2SPD-025 Application of hazard vulnerability analysis to evaluate the risk level of medicine shortages

2020

Background and importance Drug shortages have become a worldwide phenomenon which has repercussions on patient care and on the hospital’s budget. Aim and objectives The aim of our study was to assess the risk of shortages of drugs included in our hospital therapeutic formulary (HTF), for which there is shortage reporting, using a hazard vulnerability analysis (HVA). Material and methods We performed an HVA on 43 drugs in our HTF, which were also included in the Italian Medicines Agency list of shortages. The HVA used to assign the risk of shortage (ROS) included three macro areas: probability that the shortages will occur based on shortages in the past 2 years; magnitude factors which incre…

An integrated framework for risk profiling of breast cancer patients following surgery.

2006

Objective: An integrated decision support framework is proposed for clinical oncologists making prognostic assessments of patients with operable breast cancer. The framework may be delivered over a web interface. It comprises a triangulation of prognostic modelling, visualisation of historical patient data and an explanatory facility to interpret risk group assignments using empirically derived Boolean rules expressed directly in clinical terms. Methods and materials: The prognostic inferences in the interface are validated in a multicentre longitudinal cohort study by modelling retrospective data from 917 patients recruited at Christie Hospital, Wilmslow between 1983 and 1989 and predictin…

Tumor response assessment by modified Choi criteria in localized high-risk soft tissue sarcoma treated with chemotherapy.

2012

BACKGROUND. The objective of this study was to compare the prognostic relevance of Response Evaluation Criteria in Solid Tumors (RECIST) versus Choi criteria for the assessment of response in patients with high-risk soft tissue sarcoma of the extremities or trunk wall who received preoperative chemotherapy with or without radiotherapy in a phase 3 trial. METHODS. Patients received 3 cycles of preoperative epirubicin þ ifosfamide with or without radiotherapy. The diagnostic concordance between RECIST and Choi criteria and their correlation with overall survival (OS) and freedom from progression (FFP) were evaluated in a univariate Cox regression model. RESULTS. In 243 of 321 eligible patient…

Design and implementation of the DAP 360º tool for the assessment of risk and vulnerability in childhood and adolescence

2023

Introducción. El maltrato a la infancia y la adolescencia es un problema a nivel mundial que tiene graves consecuencias que pueden durar toda la vida. La detección y evaluación eficaz del maltrato infantil se considera esencial para facilitar el proceso de toma de decisiones profesional. No obstante, en la actualidad, la descentralización de la atención, la falta de rigurosidad científica y objetiva en los diagnósticos y las evaluaciones parciales y fragmentadas pueden dificultar la adopción de medidas de protección efectivas. Objetivo. El objetivo de este estudio es presentar el proceso de diseño de la herramienta DAP 360º, creada para colaborar en el juicio profesional para la evaluación …
