Current ergonomic risk assessment tools do not assess possible occupational (extrinsic) and personal (intrinsic) risk factors for the lower extremity regions of employees. This document proposes that it is possible to develop a lower extremity risk assessment (LERA) model for quantifying such risks. A literature review was conducted for work-related musculoskeletal disorders of the lower extremity that affect the nervous, muscular, vascular, and skeletal systems. This initial model of LERA was developed using epidemiological literature and subject matter expert opinion specifically for the knee joint and is considered a preliminary step towards quantifying the etiology of cumulative occupational knee disorders.

Violence Risk Assessment

<p>The key notion of a police organisational culture unique to frontline police officers explains why police services are resilient to reform, as past attempts by police management to change the traditions of the street-cop culture have proved difficult to achieve. The key tenets of the organisational culture of frontline policing see street-level police negotiate and resist aspects of the NZ Police family violence risk assessment model to which they do not subscribe. Frontline officers' resistance is an expression of their attitudes and beliefs about 'real' police work. These beliefs are informed by the occupational subculture of which they are a part. Officers in this study also resist the increasing bureaucratisation of their role and oppose attempts by management to change the informal rules by which they operate. The established autonomy and isolation of frontline policing allows officers discretion in their implementation of the risk assessment model. This thesis examines the experiences of frontline police officers responsible for implementing family violence risk assessment, in selected areas of the Waikato District. The study employed face to face semi-structured interviews with frontline police officers and sought accounts of their experiences of responding to family violence and their use of the risk assessment tools. The research found that officers recognise and support the improvement of the police response to victims of family violence. Despite this, the introduction of family violence risk assessment in the Waikato District has achieved limited change. This study found considerable evidence of a discrepancy between management policy and operational practice, as the risk assessment model is neither implemented as intended by police management or for which it was designed. This is the result of issues with training and tensions between management directives and established practice at the frontline. These challenges faced by NZ Police are typical of the problems encountered by police organisations implementing similar reforms in other Western jurisdictions.</p>

Abstract Introduction The incidence of flap failure in lower extremity reconstruction is significantly higher in the lower extremity compared head, neck and breast reconstruction. The commonest cause of flap failure is venous thrombosis. The aim of this study was to assess the reliability of VTE risk assessment tools in patients with open lower extremity fractures and to assess the ability of such tools to identify patients at risk of developing microvascular venous thrombosis following lower extremity free flap reconstruction. Method A single centre retrospective cohort study was conducted between August 2012-August 2019. All patients were risk assessed using the Department of Health (DoH), Modified Caprini and Padua VTE risk assessment tools. Result 58 patients were included, all were at high risk of DVT according to the DoH (mean score± SD, 3.7±0.93), Caprini (10.2±1.64) and Padua (5.4±0.86) risk assessment tools. All patients received thromboprophylaxis, the incidence of clinical deep venous thrombosis was 0%. Intraclass correlation coefficient demonstrated moderate agreement between the Caprini and DoH (0.73, 95% CI 0.54-0.84, p&lt;0.001), the Caprini and Padua (0.52, 95% CI 0.19-0.72, p&lt;0.001) and the DoH and Padua (0.74, 95% CI 0.57-0.85, p&lt;0.001). Microvascular venous thrombosis occurred in 6 patients, resulting in 2 amputations. There were no significant differences in scores between those with and without venous complications. Conclusion Current VTE risk assessment tools do not identify patients at risk of developing venous complications following lower extremity reconstruction. Further prospective studies are required to optimise risk prediction models and thromboprophylaxis use in this cohort. Take-home message Current VTE risk assessment tools do not identify patients at risk of developing microvascular venous thrombosis following lower limb reconstruction.

Most of the current construction risk assessment tools deliver unsatisfactory results because the prerequisite for their effective applications rely on the availability of high quality data especially during the early stage of a project. Unfortunately, such data are limited, ambiguous or even not exist due to the great uncertainty inherent in construction projects. Based on Fuzzy Synthetic Analysis (FSA), a model development team was formed among construction engineers, IT professionals, and Mathematicians in developing a holistic risk assessment model to estimate the construction risks especially for the situations with incomplete data and vague environments. Through qualitative scales defined by triangular fuzzy numbers used in pairwise comparisons to capture the vagueness in the linguistic variables, a risk assessment model using Analytic Hierarchy Process (AHP) was developed. The Pilot Run revealed the developed Fuzzy Synthetic Model (FSM) could accelerate the decision-making process and provide optimal allocation of project resources to mitigate possible risks detrimental to the success of a project in terms of time, cost, and quality.

Musculoskeletal disorders are one of the most common occupational diseases, affecting millions of workers in the European Union and costing employers billions of euros. Researching the relationships and possibilities of optimal mutual adaptation, under given conditions, both of human to his work and of work to humans, in order to increase the technical-economic efficiency, to optimize the conditions of satisfaction, motivation and work results, while maintaining the worker’s state of health also involves, as a basic stage, the assessment of the risks of osteomuscular-articular overload. Starting from a statistical synthesis on the incidence of MSD and the characteristic types of demands, the paper systematizes in a unitary vision the categories of methods, techniques and tools available for recording and evaluating the factors of physical and postural stress of workers. The pointed description of three of the most commonly applied ergonomic risk assessment tools, aimed at developing a synthesis of Strengths-Weaknesses type, which highlights the advantages of methods in counterbalance with their limitations, providing a first basis for selection in order to apply them in the practice of companies that are aware that investing in safety means investing in profit and not losing financial resources and implicitly human, material ones.

Abstract Background The objective of this study was to establish a risk assessment model for lower extremity deep venous thrombosis in critically ill patients and compared with Caprini, Padua and Wells risk assessment model to evaluate its efficacy. Methods We conducted a pooled analysis of prospective cohort studies. The outcomes of interest were lower extremity deep vein thrombosis group and Non-lower extremity deep vein thrombosis group were determined by univariate analysis, and SPSS was used to establish the back propagation artificial neural network prediction model. ROC curve was used to evaluate the predictive effectiveness of the model. Medcalc15.2 was used to compare the predictive capabilities of different models. Results 600 cases of intensive care unit patients were selected in this study. The prevalence of lower extremity venous thromboembolism after ICU admission was 12.5%. The results of univariate analysis that showed 16 statistically significant difference influencing factors. The ROC curve area of BP-ANN risk assessment model was 0.828, showing good predictive efficacy. In addition to the ROC curve area of BP-ANN risk assessment model was higher than Caprini, Padua and Wells model. Conclusion BP-ANN risk assessment model can play an auxiliary role in predicting the occurrence of lower extremity venous thromboembolism in critically ill patients. This model can provide a reference for medical staff to take preventive management measures.
