Assessment of the baseline thoroughness of cleaning at one hospital dialysis suite

Molyneux, Melissa 04 1900 (has links)
A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / One fifth to one third of hemodialysis patients develop infections from bacterial and viral pathogens over the total course of their treatment, many of which are healthcare acquired, leading to significant morbidity and mortality. Over recent years, significant strides have been made to decrease the rate of healthcare-acquired infections (HAIs) by reducing the risk of transmission of pathogens, including increased compliance to hand-washing of healthcare workers (HCW) and improved quality of environmental cleaning. The goal of the project was to improve the thoroughness of cleaning of a hemodyalysis (HD) suite using objective monitoring and a program of education and feedback. To achieve this goal, the project was broken down into three aims: 1. Determine the baseline thoroughness of cleaning using a novel marker system; 2. Educate and provide feedback to hospital administration and environmental services staff involved in overseeing and in cleaning the HD suite, and; 3. Determine if the program improves the thoroughness of cleaning when compared to baseline. Due to institutional constraints, the third aim of the project was not performed. This investigation demonstrated a baseline thoroughness of cleaning for all high-touch surfaces to be 42% of surfaces cleaned, indicating there are opportunities for improvement in the sanitation practices of the hospital hemodialysis suite. Most individual surface types fell below the internal goal of 90% cleaned. Through presenting the baseline data to hospital administration and environmental services staff, areas of potential improvement in hemodialysis suite sanitation practices were identified, which included the assignment of the cleaning of individual surfaces to specific hospital departments. Though the follow-up testing could not be performed, it is likely that the identification of these areas for process improvement resulted in increased cleaning of overlooked surfaces.

Cochlear Luere

Segergren, Magnus, Ogenvall, Lukas January 2008 (has links)
<p>The goal of this project was to together with Cochlear Bone Anchored Solutions AB develop a new cleaning tool for their Baha‐systems. Cochlear BAS AB is a daughter company to Cochlear Limited based in Sydney, Australia. Cochlear BAS AB is situated in Gothenburg and with its 150 employees develop and manufacture the Baha‐system. Baha is a bone anchored hearing aid which involves a minor surgery placing a titan implant, or abutment in the skull bone behind the client’s ear. By placing a sound processor which converts sound into vibrations on the abutment which then acts as a pathway for the vibrations to reach the skull and finally the cochlea giving clients improved hearing. Due to the fact that the skin never really fuses with the abutment daily cleaning is required of and two centimeters around the abutment.

Garbage cleaning privatization is one major task for Taiwan EPA

Wu, Wha-Kwo 13 August 2004 (has links)
As in the new century, privatization has become a global trend for various public works. Garbage cleaning privatization is one major task for Taiwan EPA; all government divisions change their row from carrier to supervisor, since, the local government cans more effective in supervision and management. The results for in foreign countries have more positive effect than negative, therefore, it is expected that the privatization garbage cleaning can turn the government burden into private aid by correcting the old system. In Kaohsiung, a milestone has been set since the new mayor has subcontract the garbage cleaning to private sector. This thesis is aim for the related problems and difficulties after the garbage cleaning privatization, especially the ratio between government and private sector, from literature review, real case investigation, censer, and interview, four different approaches. The content is started with theory, definition, and foreign documents, to discuss the garbage cleaning privatization, then get into the real cases in Taiwan and other countries, and hopefully finding the best resolution for kaohsiung city in this area. At the end of this thesis, a practicable proposal for garbage cleaning privatization will be recommended based on the conclusion form survey and interview with private sectors.

Cleaning of Printed Circuit Assemblies with Surface-Mounted Components

Arzigian, J. S. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / The need for ever-increasing miniaturization of airborne instrumentation through the use of surface mounted components closely placed on printed circuit boards highlights problems with traditional board cleaning methods. The reliability of assemblies which have been cleaned with vapor degreasing and spray cleaning can be seriously compromised by residual contaminants leading to solder joint failure, board corrosion, and even electrical failure of the mounted parts. In addition, recent government actions to eliminate fully halogenated chlorofluorocarbons (CFC) and chlorinated hydrocarbons from the industrial environment require the development of new cleaning materials and techniques. This paper will discuss alternative cleaning materials and techniques and results that can be expected with them. Particular emphasis will be placed on problems related to surface-mounted parts. These new techniques may lead to improved circuit reliability and, at the same time, be less expensive and less environmentally hazardous than the traditional systems.
