Sistema de notificação de eventos adversos : contributos para a melhoria da segurança do doente

RESUMO - Este estudo insere-se na temática dos sistemas de notificação de eventos adversos. Pretende-se compreender a necessidade e importância de implementação de um sistema de notificação de Eventos Adversos num hospital E.P.E. (entidade pública empresarial) de Lisboa. Apresenta como objectivo geral: •Identificar as principais características que um Sistema de Notificação de Eventos Adversos, Erros e Incidentes deve ter e com base nisso propor um formulário de notificação que assente numa lógica de aprendizagem e não numa perspectiva de culpabilização. Trata-se de um estudo exploratório, descritivo, quantitativo, transversal. Foi utilizado como instrumento de recolha de dados o inquérito por questionário. A amostra é constituída por 82 enfermeiros de um hospital de Lisboa, em que não está implementado sistema de notificação de eventos adversos. Após análise dos dados concluiu-se que: Quando ocorrem acontecimentos indesejáveis, os profissionais de enfermagem poucas vezes notificam; Os profissionais notificam com maior frequência quando o evento é grave e trágico; Os inquiridos apontam como principais factores para a ocorrência de eventos adversos/erros/incidentes no seu local de trabalho “falhas de comunicação” e “deficiente rácio enfermeiro/doente”; A maior parte dos inquiridos concorda com a implementação de um sistema de notificação de eventos adversos, erros e incidentes no hospital onde trabalham. O sistema deve ser de carácter obrigatório assegurando o anonimato. Espera-se que o presente trabalho seja um contributo importante, que entronque e potencie a política/estratégia definida pelo hospital para a área da segurança do doente.

Equity in access to MRI equipment: the Portuguese case

Magnetic resonance imaging (MRI) is a method of image diagnose proven to be of undeniable importance when it comes to neuro and cardio related diseases. In fact, these diseases (such as: ischemic heart disease, stroke and acute myocardial infection) have high incidence in Portugal. For these reasons, the allocation of this medical technology should not be considered with light thoughts. In fact, making decision of resource allocation in health care can be a very complex and contested matter. The impacts of new technology allocation, such MRI, can be assessed in a variety of ways. However, a fundamental component should always be present: the use of evidence-based decision-making methods. One of these methods is Technology Assessment (TA). This paper aims to characterize the equity on access of the Portuguese population in general, to a specific medical device such as MRI, under the TA point of view. It is hoped to promote a bridge of scientific knowledge between the gap on research and policy-making through TA that can emerge as a tool to aid decision-makers in the organization of health systems. There are gaps in providing healthcare, due to geographical imbalances, with some areas unable to provide certain specialized services, as hospitals in the countryside do not provide all medical specialties. Portugal has also a large independent private sector that provides diagnostic and therapeutic services to NHS users under contracts called conventions. These medical contracts cover ambulatory health facilities for laboratory tests and examinations such as diagnostic tests and Radiology. However, there is no convention from the NHS when concerning the MRI exam. Therefore, this reality can be considered a limitation in the access of the general population to this kind of clinical exam. TA can play an useful and important role in helping the decision-makers to explore potential gains that might be achieved by introducing a more rational decision making into health care management, namely into the Radiology area, regarding the allocation of MRI equipment.

Ecology of Phlebotomine sandflies (Diptera, Psychodidae) in Brazilian Atlantic Forest

The phlebotomine sandfly fauna of a primary forest reserve at Morretes (eastern Paraná State) was studied, using CDC-like light traps, one night per month, at canopy and ground level, between April 1995 and March 1996. A total of 3,106 insects were collected, identified as belonging to nine species. Lutzomyia ayrozai and Lu.geniculata were predominant, seven other species also being present. Monthly mean temperature, rainfall and the temperature of the collection night significantly influenced the numbers of Lu. ayrozai while the two first factors influenced the numbers of Lu. geniculata, besides the collected quantities of females of the two species. The influence of the factors on Lu. ayrozai numbers was more immediate than in those of Lu. geniculata. Numbers of both species and of the females of Lu. geniculata collected in different seasons, but not at the different heights, varied significantly. Differences between the behaviour of Lu. ayrozai in Morretes and in other regions could be attributed to environmental differences and/or to regional variations in the species, which could constitute species complexes. Hourly variations of collections were different in the species and seasons.

Achieving better service level results, through improvements in procedures

This project aims to prepare Worten Empresas (WE) fulfilling the increasing market demand through process changings, focusing on the Portuguese market, particularly on internal B2B clients1. Several methods were used to measure the current service level provided - process mapping, resources assessment, benchmark and a survey. The results were then used to compare against service level actually desired by WE’s customer, and then to identify the performance gaps in response times and quality of the follow-up during the sales process. To bridge the identified gaps, both a set of recommendations and an implementation plan were suggested to improve and monitor customer experience. This study concluded that it is possible to fulfill the increasing level of demand and at the same time improve customer satisfaction by implementing changes at the operations level.

A CMMI-compliant requirements management and development process

Requirements Engineering has been acknowledged an essential discipline for Software Quality. Poorly-defined processes for eliciting, analyzing, specifying and validating requirements can lead to unclear issues or misunderstandings on business needs and project’s scope. These typically result in customers’ non-satisfaction with either the products’ quality or the increase of the project’s budget and duration. Maturity models allow an organization to measure the quality of its processes and improve them according to an evolutionary path based on levels. The Capability Maturity Model Integration (CMMI) addresses the aforementioned Requirements Engineering issues. CMMI defines a set of best practices for process improvement that are divided into several process areas. Requirements Management and Requirements Development are the process areas concerned with Requirements Engineering maturity. Altran Portugal is a consulting company concerned with the quality of its software. In 2012, the Solution Center department has developed and applied successfully a set of processes aligned with CMMI-DEV v1.3, what granted them a Level 2 maturity certification. For 2015, they defined an organizational goal of addressing CMMI-DEV maturity level 3. This MSc dissertation is part of this organization effort. In particular, it is concerned with the required process areas that address the activities of Requirements Engineering. Our main goal is to contribute for the development of Altran’s internal engineering processes to conform to the guidelines of the Requirements Development process area. Throughout this dissertation, we started with an evaluation method based on CMMI and conducted a compliance assessment of Altran’s current processes. This allowed demonstrating their alignment with the CMMI Requirements Management process area and to highlight the improvements needed to conform to the Requirements Development process area. Based on the study of alternative solutions for the gaps found, we proposed a new Requirements Management and Development process that was later validated using three different approaches. The main contribution of this dissertation is the new process developed for Altran Portugal. However, given that studies on these topics are not abundant in the literature, we also expect to contribute with useful evidences to the existing body of knowledge with a survey on CMMI and requirements engineering trends. Most importantly, we hope that the implementation of the proposed processes’ improvements will minimize the risks of mishandled requirements, increasing Altran’s performance and taking them one step further to the desired maturity level.

Comportamentos Pró-ambientais numa Sociedade de Consumo

Embora os avanços científicos tenham um papel preponderante na resolução dos problemas ambientais associados às alterações climáticas, à utilização de energia e aos estilos de vida actuais, a médio e longo prazo a eficácia dessas tecnologias e das políticas de suporte das mesmas vai depender em grande medida das mudanças de comportamento e de atitudes por parte de organizações e indivíduos – no domínio privado, nas comunidades, nas empresas e no sector público. Compreender as mudanças no comportamento das pessoas para acções mais pro-ambientais é, portanto, uma parte essencial para redefinir o futuro. Os problemas ambientais só serão resolvidos com políticas baseadas numa clara compreensão dos factores que influenciam as intenções e atitudes individuais. Para se alterar um comportamento, é necessário compreender esse mesmo comportamento. Para além de ter um grande poder de compra actualmente, a população juvenil representa o grupo de consumidores do futuro: com a personalidade já formada, é importante perceber que ideias orientam as suas práticas. Deste modo, e no quadro de uma sociedade de consumo cada vez mais consolidada em Portugal, procuramos apreender os hábitos de consumo que pautam o quotidiano dos estudantes universitários face às suas preocupações de índole ambiental. Para tal, foi aplicado um inquérito que partiu da adaptação da escala NEP (New Ecological Paradigm, Dunlap et al, 2000) em associação a questões relacionadas com padrões de consumo, gaps de comportamento pró-ambiental, ligação ao campus e felicidade, e que visa conhecer consciência ambiental dos estudantes da FCSH.

A moderna integração das lacunas: o caso português

Assuming a concrete dispute that has no legal answer in the Portuguese civil statutes, this article attempts to discover the right solution according to existing doctrinal and legal materials. We begin with a brief analysis of the answer, as it would be provided by the modern theory of law to said dispute. This answer will then be compared with the result that is found in accordance with Article 10(3) of the Portuguese civil code (provision on legal gaps).

Adesão terapêutica e hipertensão arterial : o uso de fontes administrativas de dados de prescrição e levantamento de medicação na estimação da adesão à terapêutica com antagonistas dos recetores da angiotensina

RESUMO - Objetivos: São objetivos do presente estudo caraterizar a adesão terapêutica, primária e secundária, na Região de Saúde do Alentejo em utentes que seguiram tratamento para Hipertensão Arterial com Antagonistas dos Receptores da Angiotensina e constatar se a adopção de diferentes medidas produz diferentes resultados de adesão terapêutica. Metodologia: Este estudo é uma análise retrospetiva da prescrição e levantamento de ARA nos anos de 2010 e 2011 na Região de Saúde do Alentejo. Foram considerados 22.450 utentes e cinco diferentes medidas de adesão terapêutica: Rácio de Adesão Primária, Medication Possession Ratio, Compliance Rate, Refill Compliance Rate, Continuous Measure of Medication Gaps. Resultados: Constatou-se que a adesão terapêutica primária para os 22.450 utentes considerados na amostra foi de 0,612 (DP 0,325), a adesão terapêutica medida pelo indicador MPR foi de 0,557 (DP 0,380), pelo indicador CR foi de 0,697 (DP 0,517), pelo indicador RCR foi de 0,695 (DP 0,518) e pelo indicador CMG foi de 0,648 (DP 0,351). Independentemente do indicador considerado, a adesão terapêutica foi mais elevada no sexo feminino do que no sexo masculino, os utentes do sexo feminino apresentaram níveis de sobre-aquisição de medicação mais elevados e a prevalência de utentes que no período não chegaram a levantar nenhuma embalagem de medicação, não obstante a necessidade clínica ter sido identificada em pelo menos 2 momentos no período, foi mais elevada no sexo masculino. As faixas etárias acima dos 70 anos apresentaram níveis médios de adesão terapêutica significativamente superiores aos verificados nas faixas etárias que compreendem os utentes em idade ativa. Constatou-se que os concelhos que apresentaram resultados de adesão terapêutica inferiores à média amostral por um determinado indicador, em regra, viram confirmada essa tendência pelos restantes indicadores. Não obstante, verificou-se que os rankings de desempenho obtidos pelos cinco indicadores apresentaram concordância estatística fraca. Conclusões: Concluiu-se que, não obstante a existência de um conjunto de limitações e condicionalismos metodológicos, os dados atualmente recolhidos ao nível da prescrição e conferência de receituário permitem a mensuração dos comportamentos de adesão terapêutica. A inexistência de consenso científico terminológico tem conduzido à proliferação de indicadores com o fito de medir a adesão terapêutica que, sendo conceptualmente distintos na sua construção, conduzem a diferentes resultados de adesão terapêutica. Os resultados obtidos pelo presente estudo permitiram confirmar este aspecto pelo que não se recomenda a utilização de apenas um indicador para análise dos comportamentos de adesão terapêutica dos utentes.

Co-infection Trypanosoma cruzi/HIV: systematic review (1980 - 2010)

INTRODUCTION: The co-infection Trypanosoma cruzi/HIV has been described as a clinical event of great relevance. The objective of this study wasto describe clinical and epidemiological aspects published in literature. METHODS: It is a systematic review of a descriptive nature from the databases Medline, Lilacs, SciELO, Scopus, from 1980 to 2010. RESULTS: There were 83 articles (2.8 articles/year) with a total of 291 cases. The co-infection was described in 1980 and this situation has become the defining AIDS clinical event in Brazil. This is the country with the highest number of publication (51.8%) followed by Argentina (27.7%). The majority of cases are amongst adult men (65.3%) native or from endemic regions with serological diagnosis in the chronic stage (97.9%) and indeterminate form (50.8%). Both diseases follow the normal course, but in 41% the reactivation of the Chagas disease occurs. The most severe form is the meningoencephalitis, with 100% of mortality without specific and early treatment of the T. cruzi. The medication of choice was the benznidazole on doses and duration normally used for the acute phase. The high parasitemia detected by direct or indirect quantitative methods indicated reactivation and its elevation is the most important predictive factor. The lower survival rate was related to the reactivation of the Chagas disease and the natural complications of both diseases. The role of the antiretroviral treatment on the co-infection cannot yet be defined by the knowledge currently existent. CONCLUSIONS: Despite the relevance of this clinical event there are still gaps to be filled.

Ecological aspects of mosquitoes (Diptera: Culicidae) in the gallery forest of Brasilia National Park, Brazil, with an emphasis on potential vectors of yellow fever

Introduction We analyzed the vertical and monthly distributions of culicid species in the gallery forest of Brasília National Park, with an emphasis on the potential vectors of yellow fever (YF). Methods Between September 2010 and August 2011, mosquitoes were captured on the ground and in the canopy of the forest for five consecutive days per month, from nine to 15 hours. The mosquitoes were examined to verify natural infection with flaviviruses by isolation in Aedes albopictus Skuse, 1864 cells followed by indirect immunofluorescence. Results We identified 2,677 culicids distributed in 29 species. Most of the mosquitoes were captured at ground level (69%) during the rainy season (86%). The most abundant species were Sabethes (Sabethes) albiprivus Theobald, 1903; Limatus durhamii Theobald, 1901; Haemagogus (Conopostegus) leucocelaenus Dyar & Shannon, 1924; Haemagogus (Haemagogus) janthinomys Dyar, 1921; Aedes (Ochlerotatus) scapularis Rondani, 1848; Psorophora (Janthinosoma) ferox Von Humboldt, 1819; and Aedes (Ochlerotatus) serratus Theobald, 1901. Limatus durhamii, Limatus durhamii, Psorophora ferox, Aedes scapularis and Aedes serratus showed significant differences (p<0.05) in their habitat use. Limatus durhamii was found more often in the canopy, unlike the other species. During the rainy season, the most abundant species were Sa. albiprivus, Haemagogus leucocelaenus and Limatus durhamii. During the dry season, the potential YF vectors exhibited a very low frequency and abundance, except Aedes scapularis and Aedes serratus. No flavivirus was detected in the 2,677 examined mosquitoes. Conclusions We recommend continued and systematic entomological monitoring in areas vulnerable to the transmission of YF in the Federal District of Brazil.
