Diagnóstico e análise funcional da implementação do Sistema Pyxis no Serviço de Urgência do Hospital Espírito Santo- Évora

Atualmente, existe interesse em determinar o benefício ou contributo do estudo de um determinado tópico para a prática em enfermagem e melhoria do serviço ao utente, o que é percetível na necessidade detetada nessa prática de disponibilizar o medicamento no local adequado, na quantidade exigida e no tempo e gasto mínimos. Neste sentido, verifica-se que o Hospital do Espirito Santo Évora (HESE) adquiriu o sistema Pyxis em 2007 e, até à data, não foi implementado sem se perceber as razões para tal, quer sejam de natureza técnica quer de gestão, o que desperta o interesse no tratamento deste assunto e a relevância do tema. Assim, levanta-se a questão sobre as condições de implementação do Pyxis, o que se traduz num problema, para o qual se procura uma solução com uma metodologia adequada. O presente trabalho tem como objetivo preparar as condições para a implementação do Pyxis. Assim, pretende-se analisar a situação presente e identificar as necessidades de alteração e de ajustamento suportadas nas exigências e requisitos do sistema Pyxis, no que se refere à sua implementação. Em termos metodológicos, para prosseguir o objetivo antes referido, recorre-se ao diagnóstico interno, à descrição do Pyxis, para identificação das condições da sua implementação, à análise funcional e à elaboração do instrumento de inquérito através de questionário, para posterior aplicação. Os resultados obtidos permitem uma verificação dos requisitos e alterações, para a implementação do sistema Pyxis, bem como os benefícios associados a este sistema. Existe a evidência de que o sistema Pyxis é uma nova tecnologia que possibilita ao HESE a diminuição do tempo utilizado pela equipa de saúde no processo logístico de distribuição do medicamento e a melhoraria da qualidade através da diminuição de erro de medicação, sendo fundamental na qualidade dos cuidados de saúde a prestar aos utentes, o que é concordante com o enquadramento teórico efetuado

Use of medications on the elderly

The elderly constitute a growing world population group, with more than 200 million people over 60 years of age. This fact has increased the detection of chronic-degenerative diseases, as well as the prescription and consumption of medicines. The elderly are particularly susceptible to adverse drug events or interactions with other drugs due to their physiological changes, genetic predisposition and environmental exposure. It becomes necessary to adapt the health systems with integral and multidisciplinary approaches suitable to this demographic change, as the knowledge about appropriate prescription, clinical pharmacology and medication use in the elderly has become essential. It has been shown that about two thirds of elderly patients receive inappropriate drug doses, and a substantial percentage of their hospital admissions are associated with potentially preventable toxic effects of drugs. To date, expert criteria, error detection tools and educational prescription plans have been developed by expert consensus for the safe use of drugs in the geriatric population. The objective of this study is a brief review of the principal physiological changes in an older adult, and summarize the contributions of the consensuses on prescription.

O papel dos sistemas de informação do Hospital de Curry Cabral na gestão hospitalar : Estudo de caso num serviço de radiologia

Os sistemas de informação, enquanto ferramenta da gestão, podem contribuir para o desenvolvimento das organizações sendo atualmente visível esta preocupação nos órgãos de gestão dos serviços de saúde. No processo de implementação dos sistemas de informação a economia da informação assume um destaque pela sua componente de mais-valia. No presente trabalho, fizemos uma caracterização dos sistemas de informação utilizados no serviço de radiologia do hospital Curry Cabral e percebemos como os profissionais trabalhavam e atualizavam a informação nesses mesmos sistemas. Analisámos posteriormente a produtividade através de índices criados para o próprio serviço, antes e depois da implementação dos sistemas de informação, para entender até que ponto podemos falar da economia da informação. Através de uma abordagem quantitativa pretendeu-se a realização de um estudo descritivo com recurso à técnica de inquérito através de questionário aplicado a 55 profissionais do serviço, nomeadamente a 17 médicos de radiologia, a 6 administrativas e a 31 técnicos de radiologia. De uma forma geral, os dados obtidos nesta investigação permitem verificar que a atualização dos sistemas de informação por parte dos profissionais deste serviço ocorre de uma forma bem conduzida e cuidada, nomeadamente pelos técnicos de radiologia. Entendemos também que de uma forma geral todos os profissionais estão cientes que os sistemas de informação contribuem para o auxílio na gestão principalmente devido a uma melhor monitorização do trabalho efetuado. Relativamente aos índices de produtividade percebemos que são difíceis de quantificar, no entanto, e de um modo geral esta aumentou em valores pouco significativos, cerca de 2,3%. ABSTRACT: The information Technology as a management tool can contribute to the healthy development of the organization. This fact has become visible by the interest showed on IT by the management body of the Health Services. On the implementation process of the IT Services the economy of information assumes a major role as a powerful and altering force to the landscape. ln this thesis we studied the IT services used by the Radiology Service of the Hospital Curry Cabral, and tried to understand how the professionals work, by using and improving the information on those systems. We analyze the productivity using markers built for the specified service, before and after the implementation of the IT Services to understand how far into the "IT Economics" we have traveled. Thru a direct approach a study was conducted using a questionnaire, and a target audience of 55 local radiology professionals, namely 17 radiology doctors, 6 service secretaries and 31 radiology technicians. ln general, the data gathered by this investigation, allowed us to verify that the data collected and updated by the Radiology professionals, is carefully collected, especially by the Radiology Technicians. We have also found that generally all Hospital professionals see the IT Services as a major help for management mainly thru better monitoring of accomplished work. ln relation to the productivity indexes we have found that they are hard to quantify, because certain aspects are close to impossible to ascertain, but in gross it has grown but in less than expected, more or less 2,3%.

Qualidade dos sistemas de informação no serviço de radiologia do Hospital de Curry Cabral

A preocupação com a qualidade dos serviços prestados pelas organizações de saúde é uma realidade. Em resultado de várias pressões e diferentes metodologias têm sido implementadas nas instituições Sistemas de Informação a fim de melhorar a qualidade e segurança dos procedimentos aí desenvolvidos. A qualidade dos Sistemas de Informação assume um destaque pela sua componente de mais-valia, neste trabalho procuramos avalia-la e verificar a sua correta implementação. A presente dissertação reporta-se ao estudo dos Sistemas de informação no Serviço de Radiologia do HCC, tendo como objetivo principal saber se os Sistemas de Informação, potenciaram a melhoria da qualidade de desempenho dos profissionais de saúde, assim como caracterizar a qualidade dos Sistemas de Informação. Como estratégia de pesquisa optamos por um estudo de natureza descritiva, utilizando um modelo de análise quantitativo. Aplicou-se um questionário elaborado pela investigadora, tendo sido aceites as respostas de 55 questionários realizados aos utilizadores dos SI. De uma forma geral os resultados demonstram que os Sistemas de Informação foram bem aceites por parte dos profissionais deste serviço, existindo porem algumas deficiências que não permite que se atinja níveis de qualidade elevados. Relativamente à formação depreendemos que existem algumas lacunas relativas ao processo de formação dos utilizadores, que podem ser colmatadas por uma intervenção adequada. ABSTRACT: The concern about the quality of the accounted services by the health organizations is a reality. Information Systems have been installed in many establishments as a result of many pressures and different methodologies in order to improve the quality and safety of the procedures developed in such places. The quality of the Information Systems gains relevance due to its “rise” character; on this essay we aimed to evaluate and verify its adequate execution. The present essay is about the study of the Information Systems on the Radiology Service of Hospital Curry Cabral (HCC) being its main objective to know if the Information Systems improved the performance of the health professionals, as well as to point out their quality. We decided to build a study of descriptive nature using a quantitative analysis method. We applied an inquiry elaborated by the researcher and accepted the answers of 55 inquiries made to the SI users. In general, the results revealed that the Information Systems were well accepted by the professionals of this service. However, some minor problems do not allow high standard of quality to be obtained. As regards training we understand that there are a few defaults concerning the process of formation of the users which can be surpassed if using an adequate intervention.

Talking about quality: exploring how ‘quality’ is conceptualized in European hospitals and healthcare systems

BACKGROUND: Conceptualization of quality of care - in terms of what individuals, groups and organizations include in their meaning of quality, is an unexplored research area. It is important to understand how quality is conceptualised as a means to successfully implement improvement efforts and bridge potential disconnect in language about quality between system levels, professions, and clinical services. The aim is therefore to explore and compare conceptualization of quality among national bodies (macro level), senior hospital managers (meso level), and professional groups within clinical micro systems (micro level) in a cross-national study. METHODS: This cross-national multi-level case study combines analysis of national policy documents and regulations at the macro level with semi-structured interviews (383) and non-participant observation (803 hours) of key meetings and shadowing of staff at the meso and micro levels in ten purposively sampled European hospitals (England, the Netherlands, Portugal, Sweden, and Norway). Fieldwork at the meso and micro levels was undertaken over a 12-month period (2011-2012) and different types of micro systems were included (maternity, oncology, orthopaedics, elderly care, intensive care, and geriatrics). RESULTS: The three quality dimensions clinical effectiveness, patient safety, and patient experience were incorporated in macro level policies in all countries. Senior hospital managers adopted a similar conceptualization, but also included efficiency and costs in their conceptualization of quality. 'Quality' in the forms of measuring indicators and performance management were dominant among senior hospital managers (with clinical and non-clinical background). The differential emphasis on the three quality dimensions was strongly linked to professional roles, personal ideas, and beliefs at the micro level. Clinical effectiveness was dominant among physicians (evidence-based approach), while patient experience was dominant among nurses (patient-centered care, enough time to talk with patients). Conceptualization varied between micro systems depending on the type of services provided. CONCLUSION: The quality conceptualization differed across system levels (macro-meso-micro), among professional groups (nurses, doctors, managers), and between the studied micro systems in our ten sampled European hospitals. This entails a managerial alignment challenge translating macro level quality definitions into different local contexts.

Hospital without dyspnea: Rationale and design of a multidisciplinary intervention

Dyspnea is a common and disabling symptom of respiratory and heart diseases, which is growing in incidence. During hospital admission, breathlessness is under-diagnosed and under-treated, although there are treatments available for controlling the symptom. We have developed a tailored implementation strategy directed to medical staff to promote the application of these pharmacological and non-pharmacological tools in dealing with dyspnea. The primary aim is to decrease the rate of patients that do not receive an adequate relief of dyspnea. This is a four-stage quasi-experimental study. The intervention consists in two teaching talks that will be taught in Cardiology and Respiratory Medicine Departments. The contents will be prepared by Palliative Care specialists, based on available tools for management of dyspnea and patients' needs. A cross-sectional study of dyspnea in hospitalized patients will be performed before and after the intervention to ascertain an improvement in dyspnea intensity due to changes in medical practices. The last phase consists in the creation of consensus protocols for dyspnea management based in our experience. The results of this study are expected to be of great value and may change clinical practice in the near future and promote a changing for the better of dyspnea care.

Predictors of in-hospital mortality among cardiogenic shock patients. Prognostic and therapeutic implications

Cardiogenic shock (CS) has a poor prognosis. The heterogeneity in the mortality through different subgroups suggests that some factors can be useful to perform risk stratification and guide management. We aimed to find predictors of in-hospital mortality in these patients. We analyzed all cases of cardiogenic shock due to medical conditions admitted in our intensive acute cardiovascular care unity from November 2010 till November 2015. Clinical, biochemical and hemodynamic variables were registered, as was the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile at 24 h of CS diagnosis. From a total of 281 patients, 28 died within the first 24 h and were not included in the analysis. A total of 253 patients survived the first 24 h, mean age was 68.8 ± 14.4 years, and 174 (68.8%) were men. Etiologies: acute coronary syndrome 146 (57.7%), acute heart failure 60 (23.7%), arrhythmias 35 (13.8%), and others 12 (4.8%). A total of 91 patients (36.0%) died during hospitalization. We found the following independent predictors of in-hospital mortality: age (odds ratio [OR] 1.032, 95% confidence interval [CI] 1.003–1.062), blood glucose (OR 1.004, 95% CI 1.001–1.008), heart rate (OR 1.014, 95% CI 1.001–1.028), and INTERMACS profile (OR 0.168, 95% CI 0.107–0.266). In patients with CS the INTERMACS profile at 24 h of diagnosis was associated with higher in-hospital mortality. This and other prognostic variables (age, blood glucose, and heart rate) may be useful for risk stratification and to select appropriate medical or invasive interventions.

Complicaciones perioperatorias en el manejo de corrección de escoliosis en un hospital de tercer nivel en la ciudad de Bogotá entre el 2010-2014

Introducción: la escoliosis, definida como una deformidad de la columna vertebral en más de 10 grados, se agrupa en 4 orígenes distintos: idiopática, congénita, neuromuscular y sindromática. Cada una de ellas con diferente riesgo de progresión en severidad, lo que determina la necesidad de corrección quirúrgica para cada caso en su tratamiento. Conocer las probabilidades de complicación en la etapa peri operatoria, abre la posibilidad de dar asesoría integral que mida la relación riesgo - beneficio de la medida terapéutica. Métodos: se realiza un estudio retrospectivo de corte transversal. La información se obtiene de los registros de las historias clínicas desde el año 2010 al 2014, de pacientes intervenidos quirúrgicamente para la corrección de escoliosis. Resultados: Se obtuvieron 318 registros de procedimientos en 230 pacientes. El tipo de escoliosis presentado con mayor frecuencia es de origen idiopático 108 (47%); en los 4 tipos de escoliosis se observa mayor número de mujeres 169 (73,4%). La edad donde se concentran la mayor cantidad de cirugías para corrección de escoliosis está entre 10 - 14 años. De 13 complicaciones seleccionadas, aquellas de origen respiratorio son las de mayor probabilidad de ocurrencia (OR 30 - sig 0,000). La característica sociodemográfica “edad” logra predecir el 46% de las complicaciones perioperatorias. Discusión: La corrección de escoliosis va acompañada de comorbilidades, datos sociodemográficos y diagnósticos que en conjunto determinan el grado de complicación peri operatoria. Se necesitan registros clínicos muy completos para poder determinar la asociación entre la etiología de la escoliosis con las complicaciones más comunes. Este trabajo propone y evidencia los datos de los registros clínicos como predictores de complicaciones quirúrgicas de escoliosis. Esto exige un trabajo institucional interno que garantice la calidad en los registros de datos clínicos.

Impact on hip fracture mortality after the establishment of an orthogeriatric care program in a colombian hospital

El objetivo del estudio es evaluar la mortalidad a un año en pacientes con fractura de cadera, mayores de 65 años tratados en un programa establecido de orto-geriatría. 298 se trataron de acuerdo al protocolo de orto-geriatría, se calculo la mortalidad a un año, se establecieron los predictores de mortalidad orto-geriátrico. La sobrevida anual se incremento de 80% a 89% (p = .039) durante los cuatro años de seguimiento del programa y disminuyo el riesgo de mortalidad anual postoperatorio (Hazard Ratio = 0.54, p = .049). La enfermedad cardiaca y la edad maor a 85 años fueron predictores positivos para mortalidad.

Prediction of Length of Hospital Stay in Preterm Infants - A Case-Based Reasoning View

The length of stay of preterm infants in a neonatology service has become an issue of a growing concern, namely considering, on the one hand, the mothers and infants health conditions and, on the other hand, the scarce healthcare facilities own resources. Thus, a pro-active strategy for problem solving has to be put in place, either to improve the quality-of-service provided or to reduce the inherent financial costs. Therefore, this work will focus on the development of a diagnosis decision support system in terms of a formal agenda built on a Logic Programming approach to knowledge representation and reasoning, complemented with a case-based problem solving methodology to computing, that caters for the handling of incomplete, unknown, or even contradictory in-formation. The proposed model has been quite accurate in predicting the length of stay (overall accuracy of 84.9%) and by reducing the computational time with values around 21.3%.

Development of a Whole-Genome Sequencing (WGS) approach for the characterization of Legionella environmental isolates in water systems

Legionella is a Gram-negative bacterium that represent a public health issue, with heavy social and economic impact. Therefore, it is mandatory to provide a proper environmental surveillance and risk assessment plan to perform Legionella control in water distribution systems in hospital and community buildings. The thesis joins several methodologies in a unique workflow applied for the identification of non-pneumophila Legionella species (n-pL), starting from standard methods as culture and gene sequencing (mip and rpoB), and passing through innovative approaches as MALDI-TOF MS technique and whole genome sequencing (WGS). The results obtained, were compared to identify the Legionella isolates, and lead to four presumptive novel Legionella species identification. One of these four new isolates was characterized and recognized at taxonomy level with the name of Legionella bononiensis (the 64th Legionella species). The workflow applied in this thesis, help to increase the knowledge of Legionella environmental species, improving the description of the environment itself and the events that promote the growth of Legionella in their ecological niche. The correct identification and characterization of the isolates permit to prevent their spread in man-made environment and contain the occurrence of cases, clusters, or outbreaks. Therefore, the experimental work undertaken, could support the preventive measures during environmental and clinical surveillance, improving the study of species often underestimated or still unknown.

Experimental evaluation of the z-resolution in different clinical Digital Breast Tomosynthesis systems using commercial phantoms

Digital Breast Tomosynthesis (DBT) is an advanced mammography technique based on the reconstruction of a pseudo-volumetric image. To date, image quality represents the most deficient section of DBT quality control protocols. In fact, related tests are not yet characterized by either action levels or typical values. This thesis work focuses on the evaluation of one aspect of image quality: the z-resolution. The latter is studied in terms of Artifact Spread Function (ASF), a function that describes the signal spread of a detail along the reconstructed focal planes. To quantify the ASF numerically, its Full Width at Half Maximum (FWHM) is calculated and used as a representative index of z-resolution. Experimental measurements were acquired in 24 DBT systems, of 7 different models, currently in use in 20 hospital facilities in Italy. The analysis, performed on the clinical reconstructed images, of 5 different commercial phantoms, lead to the identification of characteristic FWHM values for each type of DBT system. The ASF clearly showed a dependence on the size of the detail, providing higher FWHM values for larger objects. The z-resolution was found to be positively influenced by the acquisition angle: Fujifilm sistematically showed wider ASF profiles in ST mode (15°) than in HR mode (40°). However, no clear relationship was found between angular range and ASF, among different DBT systems, due to the influence of the peculiarities of each reconstruction algorithm. The experimental approach shown in this thesis work can be proposed as a z-resolution quality control test procedure. Contextually, the values found could be used as a starting point for identifying typical values to be included in the test, in a DBT protocol. Clearly, a statistically significant number of images is needed to do this. The equipment involved in this work is located in hospitals and is not available for research purposes, so only a limited amount of data was acquired and processed.

Efficacy Of Ethylene-diamine-tetra-acetic Acid Associated With Chlorhexidine On Intracanal Medication Removal: A Scanning Electron Microscopy Study.

The aim of this study was to evaluate the effectiveness of 17% ethylene-diamine-tetra-acetic acid (EDTA) used alone or associated with 2% chlorhexidine gel (CHX) on intracanal medications (ICM) removal. Sixty single-rooted human teeth with fully formed apex were selected. The cervical and middle thirds of each canal were prepared with Gates Glidden drills and rotary files. The apical third was shaped with hand files. The specimens were randomly divided into two groups depending on the ICM used after instrumentation: calcium hydroxide Ca(OH)(2) +CHX or Ca(OH)(2) +sterile saline (SS). After seven days, each group was divided into subgroups according to the protocol used for ICM removal: instrumentation and irrigation either with EDTA, CHX+EDTA, or SS (control groups). All specimens were sectioned and processed for observation of the apical thirds by using scanning electron microscopy. Two calibrated evaluators attributed scores to each specimen. The differences between the protocols for ICM removal were analyzed with Kruskal-Wallis and Mann-Whitney U tests. Friedman and Wilcoxon signed rank tests were used for comparison between the score of debris obtained in each root canal third. Remains of Ca(OH)(2) were found in all specimens independently of the protocol and ICM used (P > 0.05). Seventeen percent EDTA showed the best results in removing ICM when used alone (P < 0.05), particularly in those associated with CHX. It was concluded that the chelating agent 17% EDTA significantly improved the removal of ICM when used alone. Furthermore, the type of the vehicle associated with Ca(OH)(2) also plays a role in the ICM removal.

A Microleakage Study Of Gutta-percha/ah Plus And Resilon/real Self-etch Systems After Different Irrigation Protocols.

The development and maintenance of the sealing of the root canal system is the key to the success of root canal treatment. The resin-based adhesive material has the potential to reduce the microleakage of the root canal because of its adhesive properties and penetration into dentinal walls. Moreover, the irrigation protocols may have an influence on the adhesiveness of resin-based sealers to root dentin. The objective of the present study was to evaluate the effect of different irrigant protocols on coronal bacterial microleakage of gutta-percha/AH Plus and Resilon/Real Seal Self-etch systems. One hundred ninety pre-molars were used. The teeth were divided into 18 experimental groups according to the irrigation protocols and filling materials used. The protocols used were: distilled water; sodium hypochlorite (NaOCl)+eDTA; NaOCl+H3PO4; NaOCl+eDTA+chlorhexidine (CHX); NaOCl+H3PO4+CHX; CHX+eDTA; CHX+ H3PO4; CHX+eDTA+CHX and CHX+H3PO4+CHX. Gutta-percha/AH Plus or Resilon/Real Seal Se were used as root-filling materials. The coronal microleakage was evaluated for 90 days against Enterococcus faecalis. Data were statistically analyzed using Kaplan-Meier survival test, Kruskal-Wallis and Mann-Whitney tests. No significant difference was verified in the groups using chlorhexidine or sodium hypochlorite during the chemo-mechanical preparation followed by eDTA or phosphoric acid for smear layer removal. The same results were found for filling materials. However, the statistical analyses revealed that a final flush with 2% chlorhexidine reduced significantly the coronal microleakage. A final flush with 2% chlorhexidine after smear layer removal reduces coronal microleakage of teeth filled with gutta-percha/AH Plus or Resilon/Real Seal SE.
