An evaluation of a community matron service from the patients’ perspective

Community matrons are a relatively new government initiative aimed at case managing people with long-term conditions to reduce the number of emergency bed days used in hospitals. Although there have been extensive evaluations of similar case management projects, to date there has been little evaluation of the community matron's role and the perceptions patients have of this new service. One of the main Government agendas for care is to deliver a high quality service driven by the needs of the service users (DH, 2000). In order to drive this agenda, care is to deliver a high quality service driven by the needs of the service users (DH, 2000). In order to drive this agenda, it is important that the views and perceptions of people on the receiving end of the services are heard, valued and appropriate actions taken. This two part evaluative report sets out to explore how people with long-term conditions perceive the impact of community matrons and the differences this new service may have had on their lives. Questionnaires were sent to 100 patients who were currently being case-managed by a community matron to evaluate the community matron service from the patients' perspective. Part two reports on patients' perceptions of the community matron role and the influences of the role on their health.

Evaluation of particle degradation due to high-speed impacts in a pneumatic handling system

Particle degradation can be a significant issue in particulate solids handling and processing, particularly in pneumatic conveying systems, in which high-speed impact is usually the main contributory factor leading to changes in particle size distribution (comparing the material to its virgin state). However, other factors may strongly influence particles breakage as well, such as particle concentrations, bend geometry,and hardness of pipe material. Because of such complex influences, it is often very difficult to predict particle degradation accurately and rapidly for industrial processes. In this article, a general method for evaluating particle degradation due to high-speed impacts is described, in which the breakage properties of particles are quantified using what are known as "breakage matrices". Rather than a pilot-size test facility, a bench-scale degradation tester has been used. Some advantages of using the bench-scale tester are briefly explored. Experimental determination of adipic acid has been carried out for a range of impact velocities in four particle size categories. Subsequently, particle breakage matrices of adipic acid have been established for these impact velocities. The experimental results show that the "breakage matrices" of particles is an effective and easy method for evaluation of particle degradation due to high-speed impacts. The possibility of the "breakage matrices" approach being applied to a pneumatic conveying system is also explored by a simulation example.
