In healthcare, organisational changes are suggested and implemented routinely as an answer to increasing patient demands and financial restrictions. Computer simulations offer a way to test these new procedures as well as increase the knowledge about complex systems. However, there are several challenges such as time and the difficulty to integrate simulations. To cope with these problems, ontologies is proposed as a foundation for simulations. Ontologies enable transfer of semantic meaning and a standardised way to describe objects to simplify integration of simulations. As a first step in this direction, this study aims to create an ontology framework by identifying archetypical concepts in hospital processes. The developed ontology framework is based on a generic process ontology. Moreover, case studies and interviews were used to identify, define and implement concepts in the software Protégé 5.1 using OWL-DL standard. Validation was performed by mapping hospital processes defined in three case studies using the ontology framework. The resulting ontology framework consists of 146 classes, 180 instances, 34 relations and 61 attributes. The validation of the ontology framework suggested that the framework was able torelate to all terms in the hospital processes presented in the case studies. Moreover, 50% of the terms were identical or synonyms to the concepts defined in the ontology framework. This is an indication that the ontology framework serves its function to model general concepts in hospital processes. In the future, the ontology framework will be used to create computer simulations of hospital processes. The ability to transfer semantic information and thus create computer simulations which are easy to integrate, will also be tested. Moreover, the ontology framework will be expanded by analysis of more hospital processes. / Organisationsförändringar blir allt vanligare i vården på grund av ökande patientkrav och finansiella restriktioner. Datorsimuleringar erbjuder ett sätt att testa nya processer och samtidigt öka kunskapen om komplexa system. Simuleringar erbjuder dock flertalet utmaningar eftersom det är tidskrävande och integrering av simuleringar är svårt. För att hantera dessa problem föreslås ontologier som en lösning för att skapa integrerbara simuleringar. Ontologier möjliggör överföring av semantisk mening och förenklar integrering genom att beskriva objekt på ett standardiserat sätt. Målet med denna masteruppsats är att utveckla ett ontologiskt ramverk för atti senare studier skapa integrerbara simuleringar av sjukhusprocesser. Det ontologiska ramverket skapas genom att identifiera arketypiska koncept i sjukhusprocesser. Det utvecklade ontologiska ramverket baserades på en generisk processontologi, fallstudier och intervjuer som användes för att identifiera och definiera koncept. Koncepten implementerades sedan med hjälp av mjukvaran Protégé 5.1 genom OWL-DL standard. Validering genomfördes med hjälp av fallstudier genom att se hur väl det ontologiska ramverket kunde kartlägga de sjukhusprocesser som fallstudierna beskrev. Det slutgiltiga ontologiska ramverket består av 146 klasser, 180 instanser, 34 relationer och 61 attribut. Valideringen visade att det ontologiska ramverket kunde relatera till alla termer i sjukhusprocesserna som presenterades i fallstudierna. Vidare var 50% av alla termer i fallstudiernasprocesser identiska eller synonymer till koncepten definierade i det ontologiska ramverket. Detta indikerar på att det ontologiska ramverket fyller sin funktion för att modellera generella koncept i sjukhusprocesser. I framtiden ska det ontologiska ramverket användas för att skapa datorsimuleringar och berikas genom ytterligare studier av sjukhusprocesser. Ramverkets förmåga att överföra semantisk mening och på sätt skapa integrerbara datorsimuleringar ska även testas.

Com o orçamento reduzido, o governo tem buscado formas de implementar suas políticas com o menor custo. O presente trabalho tem como objetivo principal analisar a viabilidade do sistema de custeio baseado em atividades (ABC) na avaliação de políticas de saúde pública no âmbito hospitalar, tendo como referência o serviço de radiologia do Hospital das Clínicas de Pernambuco. A metodologia utilizada para o trabalho foi o estudo de caso, onde os dados foram coletados a partir de entrevistas não estruturadas aos profissionais do setor e também através de análise documental. O trabalho prático seguiu um roteiro a partir das etapas descritas por Kaplan e Cooper (1998), que foram: 1) identificar as atividades; 2) atribuir os custos a cada atividade; 3) identificar os objetos de custos; 4) alocar os custos das atividades aos objetos. Como resultado, obteve-se a comparação entre os custos dos procedimentos radiológicos obtidos pelo método ABC e o custo pago pelo Sistema Único de Saúde (SUS). O estudo possibilitou identificar que a aplicação do método ABC neste serviço de saúde criou uma contribuição para que os gestores deste hospital possam estabelecer comparabilidade dos custos obtidos pelo método de custeio atual do Hospital das Clínicas de Pernambuco e os calculados nesta dissertação, permitindo-lhes, ainda, definir qual dos métodos é o mais adequado para atender as necessidades da organização. Ademais, os resultados comprovam a viabilidade do método como instrumento de monitoramento e avaliação de políticas de saúde pública no âmbito hospitalar. / A hospital organization uses its resources available to put into practice public health policies. Due to reduced budget, the government has sought ways to implement its policies with the lowest cost. This study aims mainly to analyze the feasibility of the activity-based costing system (ABC) in the evaluation of public health policies in hospitals, having as a reference the radiology department of the Hospital das Clínicas de Pernambuco. The methodology used for the study was the case study, which the data was collected from unstructured interviews with the department's professionals and also by documentary analysis. The practical work has followed a script according to the steps described by Kaplan and Cooper (1998), which were: 1) identify the activities; 2) assign costs to each activity; 3) identify the cost objects; 4) allocate the activities costs to the objects. As a result, we obtained a comparison between the costs of radiological procedures obtained by the ABC method and the cost paid by the Unified Health System (SUS). This study allowed us to identify that the application of the ABC method in this health service has created a contribution that allows the managers of this hospital to establish comparability of costs obtained by the actual cost method at the Hospital das Clínicas de Pernambuco and by the cost calculated in this dissertation, allowing them, also to define which method is best suited to meet the organization's needs. Furthermore, the results prove the feasibility of the method as a monitoring tool and evaluation of public health policies in hospitals.
