An adequate health care resource allocation in a hospital is directly dependent upon the ability to estimate the hospital's patient census accurately. Efforts to estimate hospital's patient census are classified into two general methods: estimating from historical data, and demographic analysis. This paper takes the position that the estimate from the historical data is more economic and convenient for understanding than the estimate from the demographic analysis. Seven models that predict hospital's patient census by using the hospital's historical data are evaluated to fit the characteristics of each pattern shown in historical information. Where a microcomputer is available, this forecasting system provides detailed prediction of patient census with the comparable percentage of forecasting error among each model. Data from a ten-unit hospital in Florida is analyzed and provides a predicted patient census for the hospital's short-term plan. Results of this patient census estimating system and its advantage over the other forecasting method are discussed.

Such knowledge may arise from various sources; sources such as readings, case studies, fact investigations, document analysis, phenomena observations and any other sort of knowledge gathering activities. However, to gather knowledge is not enough. Spreading and sharing knowledge is what counts. Having in mind this concept and also having noticed the lack of literature concerning the use of cost-based systems inside medical institutions, we present here a research on the practice of a conceptual model of activity-based costs inside a Dialysis Unit, whose cost-object is the hemodyalitical session. We also verify the use and acceptance rates by the involved professionals of the aforementioned system by means of a case study followed by interviews. The ABC System has been chosen due to the belief that it is one of the best cost systems available, especially inside a health;-service environment, due to the fact that it aims to track the spending of resources by activities which are, in turn, themselves consumed by products and services. Firstly, the project presents a panorama of the Brazilian hospital system, describing the scenario in which of the country Dialysis Units are inserted. It also analyzes medical aspects related to dialysis such as chronic renal insufficiency and the dialytical processes, both very relevant and important themes in Nephrology. Secondly, we analyze the relevant aspects of the process of choosing a cost system as well as the advantages and disadvantages of each available system. Finally, we perform a case study, which follows a conceptual model, and then evaluate the use and acceptance rates of the cost system by means of various interviews with professionals involved in Nephrology. The research has indicated that the involved in Nephrology professionals find that the ABC System seems adequate for the Dialysis Unit because it allows for a more accurate analysis of the activities and tasks comprised under a dialytical session, which is the ultimate cost-object of this study. / Pesquisar compreende buscar conhecimento sob as mais diversas formas, como: leituras, estudo de caso, investiga????o de fatos, an??lises de documentos, observa????es de fen??menos dentre v??rias outras formas. Entretanto, buscar conhecimento n??o basta, ?? preciso divulg??-lo, partilh??-lo. Com base nesta vis??o e tendo evidenciado a escassez de literatura existente sobre a utiliza????o de sistemas de custos nas institui????es hospitalares, esta pesquisa objetiva oferecer sua contribui????o, apresentando a aplica????o de um modelo conceitual de custeio baseado em atividades em uma Unidade de Di??lise, cujo objeto de custo ?? a sess??o de hemodi??lise, bem como verificar a utiliza????o e aceita????o do referido sistema mediante um estudo de caso seguido de entrevistas. Foi escolhido o Sistema ABC em decorr??ncia deste m??todo estar sendo apontado como uma das melhores metodologias de custeio, principalmente na ??rea de sa??de, na medida em que busca rastrear os recursos consumidos pelas atividades que s??o consumidas pelos produtos ou servi??os. Inicialmente este trabalho apresenta um panorama do sistema hospitalar brasileiro, descreve o cen??rio das unidades de di??lise no pa??s, abordando aspectos da medicina ligados ?? di??lise como, a insufici??ncia renal cr??nica e os processos dial??ticos, temas estes de fundamental import??ncia na ??rea de nefrologia. Em seguida ?? feita uma an??lise sobre os aspectos relevantes na escolha do sistema de custos, observando as vantagens e desvantagens de cada sistema. Finalmente, aplica-se o estudo de caso que segue um modelo conceitual, e mediante entrevistas com profissionais da ??rea de nefrologia apura-se tanto a utiliza????o quanto a aceita????o deste sistema. A pesquisa revela que o m??todo ABC, para os profissionais da ??rea de nefrologia, ?? adequado para a Unidade de Di??lise por permitir uma an??lise mais apurada nas atividades e tarefas impl??citas na sess??o de hemodi??lise (objeto de custo deste estudo).
