Aplicação de um sistema de teledermatologia no Hospital do Divino Espírito Santo nos Açores : análise custo-efectividade

RESUMO - Nos Açores, a telemedicina representa uma mais-valia para os seus habitantes devido à sua dispersão geográfica e aos elevados custos que as instituições de saúde incorrem na deslocação dos utentes e profissionais de saúde. A teledermatologia tem sido referenciada como uma das sub-especialidades da telemedicina, apresentando resultados semelhantes aos da consulta convencional em termos de fiabilidade e precisão no diagnóstico. No contexto açoriano, a teledermatologia pode ajudar a colmatar a falta de resposta por parte das instituições de saúde nesta especialidade, assim como poupar recursos às mesmas. OBJECTIVOS: Pretende-se realizar uma análise de custo-efectividade da teleconsulta em dermatologia no Hospital do Divino Espírito Santo em Ponta Delgada, na perspectiva do hospital, tendo como comparador a consulta convencional. METODOLOGIA: Realizou-se uma revisão da literatura de estudos de custo-efectividade para averiguar os recursos que deveriam ser considerados. Os recursos identificados seriam posteriormente valorizados de acordo com os custos verificados no hospital. RESULTADOS: O custo com o transporte dos doentes representa um peso bastante elevado para o Hospital, assim como a comparticipação de despesas de alojamento e alimentação dos doentes. Dado a constante deslocação de doentes entre as ilhas dos Açores e o Continente, a teledermatologia apresenta-se como uma solução viável em termos de custos e diagnóstico, comparando com a prática convencional. CONCLUSÕES: Na perspectiva do Hospital, a teledermatologia permite reduzir os custos relacionados com o transporte dos doentes entre as ilhas dos Açores e Continente, assim como despesas com alojamento e alimentação, considerados evitáveis. ------- ABSTRACT - In Azores, telemedicine represents an added-value for its population due to its geographic dispersion and to the high costs that health institutions incur to transport patients and health providers. Teledermatology has been highlighted as a telemedicine sub-specialty, presenting similar results comparing to the traditional consult, in terms of precision and reliability. In the Azorean context, teledermatology could help to diminish the lack of response of the health institutions on this specialty, as well as spare its resources. OBJECTIVES: In this project, is intended to carry out a cost-effectiveness analysis of the dermatology teleconsult in the Hospital do Divino Espírito Santo, in Ponta Delgada, on the Hospital perspective, comparing to the conventional consult. METHODOLOGY: A literature revision of cost-effectiveness studies was accomplished in order to find out what resources should be considered. The identified resources would be afterward valued according to the costs verified in the Hospital. RESULTS: The cost associated to the patient transport represents an overweight for the hospital, as well as the expenses reimbursement relating to lodging and others that patients have to incur. Due to the constant transport of patients between the Azores islands and the mainland, teledermatology constitutes a viable solution in terms of cost and diagnosis, comparing to conventional practice. CONCLUSIONS: On the Hospital perspective, teledermatology allows to reduce the costs relating to patients transport between the Azores islands and the mainland, as well as expenses with lodging and others, considered avoidable.

A domain specific language for domotic systems

To cope with modernity, the interesting of having a fully automated house has been increasing over the years, as technology evolves and as our lives become more stressful and overloaded. An automation system provides a way to simplify some daily tasks, allowing us to have more spare time to perform activities where we are really needed. There are some systems in this domain that try to implement these characteristics, but this kind of technology is at its early stages of evolution being that it is still far away of empowering the user with the desired control over a habitation. The reason is that the mentioned systems miss some important features such as adaptability, extension and evolution. These systems, developed from a bottom-up approach, are often tailored for programmers and domain experts, discarding most of the times the end users that remain with unfinished interfaces or products that they have difficulty to control. Moreover, complex behaviors are avoided, since they are extremely difficult to implement mostly due to the necessity of handling priorities, conflicts and device calibration. Besides, these solutions are only reachable at very high costs, yet they still have the limitation of being difficult to configure by non-technical people once in runtime operation. As a result, it is necessary to create a tool that allows the execution of several automated actions, with an interface that is easy to use but at the same time supports all the main features of this domain. It is also desirable that this tool is independent of the hardware so it can be reused, thus a Model Driven Development approach (MDD) is the ideal option, as it is a method that follows those principles. Since the automation domain has some very specific concepts, the use of models should be combined with a Domain Specific Language (DSL). With these two methods, it is possible to create a solution that is adapted to the end users, but also to domain experts and programmers due to the several levels of abstraction that can be added to diminish the complexity of use. The aim of this thesis is to design a Domain Specific Language (DSL) that uses the Model Driven Development approach (MDD), with the purpose of supporting Home Automation (HA) concepts. In this implementation, the development of simple and complex scenarios should be supported and will be one of the most important concerns. This DSL should also support other significant features in this domain, such as the ability to schedule tasks, which is something that is limited in the current existing solutions.

Influence of employee volunteering on brand commitment

Purpose – The purpose of this paper is to explore the impact of corporate volunteering on employee bonding and to understand the barriers and motivation to participation in these events. In contrast to other studies the participants volunteer in their spare time without expecting any financial reward. Design/methodology/approach – Employees (n 3951) of a logistic company participated in the study based on an online questionnaire with 6 items and open questions. The employee sample was divided into 3 groups depending on the frequency of participation in volunteering events. Findings – Significant differences were found on bonding between the three groups. In addition, the relevance of control variables like gender, age and job level were obtained. Furthermore a moderation effect of motivation was found. The results were interpreted within the broader context that ties motivation theory, organizational identification and social exchange theory.

The emergence of product certification systems as trade barriers

This paper addresses the growing difficulties automobile manufacturers face within their after sales business: an increasing number of trade obstacles set up by import countries discriminates against the foreign suppliers and impedes the international sales of genuine parts. The purpose of the study is to explore the emergence of trade restrictive product certification systems, which affect spare parts exports of automobile manufacturers. The methodology used includes review of the literature and an empirical study based on qualitative interviews with representatives of major stakeholders of the automotive after sales business. Relevant key drivers, which initiate the introduction of technical regulations in importing countries, are identified and analysed to evaluate their effect on the emerging trade policy. The analysis of the key drivers outlines that several interacting components, such as the global competitiveness of the country, macroeconomic and microeconomic factors, and certain country-specific variables induce trade restrictive product certification systems. The findings allow for an early detection of the emergence of product certification systems and provide a means to early recognise the risks and opportunities for the sales of automotive spare parts in the automakers’ target markets. This allows the manufacturers to react immediately and adapt in time to the upcoming changes.
