Calibrated CFD simulation to evaluate thermal comfort in a highly-glazed naturally ventilated room

Natural ventilation is a sustainable solution to maintaining healthy and comfortable environmental conditions in buildings. However, the effective design, construction and operation of naturally ventilated buildings require a good understanding of complex airflow patterns caused by the buoyancy and wind effects.The work presented in this article employed a 3D computational fluid dynamics (CFD) analysis in order to investigate environmental conditions and thermal comfort of the occupants of a highly-glazed naturally ventilated meeting room. This analysis was facilitated by the real-time field measurements performed in an operating building, and previously developed formal calibration methodology for reliable CFD models of indoor environments. Since, creating an accurate CFD model of an occupied space in a real-life scenario requires a high level of CFD expertise, trusted experimental data and an ability to interpret model input parameters; the calibration methodology guided towards a robust and reliable CFD model of the indoor environment. This calibrated CFD model was then used to investigate indoor environmental conditions and to evaluate thermal comfort indices for the occupants of the room. Thermal comfort expresses occupants' satisfaction with thermal environment in buildings by defining the range of indoor thermal environmental conditions acceptable to a majority of occupants. In this study, the thermal comfort analysis, supported by both field measurements and CFD simulation results, confirmed a satisfactory and optimal room operation in terms of thermal environment for the investigated real-life scenario. © 2013 Elsevier Ltd.

Integrating molecular diagnostics into histopathology training: the Belfast model

Molecular medicine is transforming modern clinical practice, from diagnostics to therapeutics. Discoveries in research are being incorporated into the clinical setting with increasing rapidity. This transformation is also deeply changing the way we practise pathology. The great advances in cell and molecular biology which have accelerated our understanding of the pathogenesis of solid tumours have been embraced with variable degrees of enthusiasm by diverse medical professional specialties. While histopathologists have not been prompt to adopt molecular diagnostics to date, the need to incorporate molecular pathology into the training of future histopathologists is imperative. Our goal is to create, within an existing 5-year histopathology training curriculum, the structure for formal substantial teaching of molecular diagnostics. This specialist training has two main goals: (1) to equip future practising histopathologists with basic knowledge of molecular diagnostics and (2) to create the option for those interested in a subspecialty experience in tissue molecular diagnostics to pursue this training. It is our belief that this training will help to maintain in future the role of the pathologist at the centre of patient care as the integrator of clinical, morphological and molecular information.

A table-top laser-based source of short, collimated, ultra-relativistic positron beams

An ultra-relativistic electron beam passing through a thick, high-Z solid target triggers an electromagnetic cascade, whereby a large number of high energy photons and electron-positron pairs are produced. By exploiting this physical process, we present here the first experimental evidence of the generation of ultra-short, highly collimated and ultra-relativistic positron beams following the interaction of a laser-wake field accelerated electron beam with high-Z solid targets. Clear evidence has also been obtained of the generation of GeV electron-positron jets with variable composition depending on the solid target material and thickness. The percentage of positrons in the overall leptonic beam has been observed to vary from a few per cent up to almost fifty per cent, implying a quasi-neutral electron-positron beam. We anticipate that these beams will be of direct relevance to the laboratory study of astrophysical leptonic jets and their interaction with the interstellar medium.

Emotions and voting in EU referendums

There is an emerging scholarship on the emotional bases of political opinion and behaviour and, in particular, the contrasting implications of two distinct negative emotions - anger and anxiety. I apply the insights in this literature to the previously unresearched realm of the emotional bases of voting in EU referendums. I hypothesise that anxious voters rely on substantive EU issues and angry voters rely on second-order factors relating to domestic politics (partisanship and satisfaction with government). Focusing on the case of Irish voting in the Fiscal Compact referendum, and using data from a representative sample of voters, I find support for the hypotheses and discuss the implications of the findings for our understanding of the emotional conditionality of EU referendum voting. 

Meaningful and Effective? Considering Victims’ Interests Through Participation at the International Criminal Court

This article explores the role of victims in the criminal proceedings of the International Criminal Court and the extent to which their interests have impacted upon the ICC judges’ decision making in light of human rights law and victimological theorisation. The article begins by first outlining how victims’ interests can be considered in international criminal proceedings, before contrasting this role with the purpose of international criminal justice. The second part of the article examines victim participation within the ICC and how this has affected judicial decision making to assess its effectiveness. The contest between the rights of victims and the role of Prosecutor in determining the selection of charges and perpetrators is also examined in an effort to add to the current debate on victim participation at the ICC. The author finds that at the ICC, despite innovative victim provisions, victims’ interests have little impact on outcomes of the Court. The author argues that in order to ensure the Court is more responsive to victims understanding of justice it should give greater weight to their interests, which in turn is likely to improve their satisfaction with the ICC, as well as public confidence and legitimacy of the work of the Court.

Establishing the validity of English GP Patient Survey items evaluating out-of-hours care

Background A 2014 national audit used the English General Practice Patient Survey (GPPS) to compare service users’ experience of out-of-hours general practitioner (GP) services, yet there is no published evidence on the validity of these GPPS items. Objectives Establish the construct and concurrent validity of GPPS items evaluating service users’ experience of GP out-of-hours care. Methods Cross-sectional postal survey of service users (n=1396) of six English out-of-hours providers. Participants reported on four GPPS items evaluating out-of-hours care (three items modified following cognitive interviews with service users), and 14 evaluative items from the Out-of-hours Patient Questionnaire (OPQ). Construct validity was assessed through correlations between any reliable (Cochran's α>0.7) scales, as suggested by a principal component analysis of the modified GPPS items, with the ‘entry access’ (four items) and ‘consultation satisfaction’ (10 items) OPQ subscales. Concurrent validity was determined by investigating whether each modified GPPS item was associated with thematically related items from the OPQ using linear regressions. Results The modified GPPS item-set formed a single scale (α=0.77), which summarised the two-component structure of the OPQ moderately well; explaining 39.7% of variation in the ‘entry access’ scores (r=0.63) and 44.0% of variation in the ‘consultation satisfaction’ scores (r=0.66), demonstrating acceptable construct validity. Concurrent validity was verified as each modified GPPS item was highly associated with a distinct set of related items from the OPQ. Conclusions Minor modifications are required for the English GPPS items evaluating out-of-hours care to improve comprehension by service users. A modified question set was demonstrated to comprise a valid measure of service users’ overall satisfaction with out-of-hours care received. This demonstrates the potential for the use of as few as four items in benchmarking providers and assisting services in identifying, implementing and assessing quality improvement initiatives.

Oral rehabilitation for partially dentate elders: a qualitative analysis

Aims: This study aimed to gain insight into patient’s perceptions of natural tooth loss and explored their experiences of oral rehabilitation according to a functionally orientated approach (SDA) and Removable Partial Dentures (RPD).
Study Design: For this qualitative study, a purposive sample of 15 partially dentate older patients
were recruited from Cork Dental School and Hospital. These patients had previously participated in a randomised controlled clinical trial (RCT) where they were provided with either SDA treatment using adhesive bridgework or provided with Cobalt Chromium framework RPDs. In- depth interviews were undertaken and thematic analysis was utilised to interpret the data.
Results: The findings of this study indicated strong satisfaction with SDA treatment. Patients referred to the ease in which they adapted to the adhesive prostheses as they were “lightweight”, “neat” and “fixed”. Irrespective of treatment option, patients indicated that they felt
their new prostheses were durable and an improvement on previous treatments. Most patients indicated that, previous to the RCT, they had not attended a general dentist for a number of years and only then for acute issues. They had concerns that treatment which was provided to them as part of the RCT would not be available to them in primary care. Interestingly, although they do not want their condition to dis-improve, if their prostheses failed they stated that they would not seek alternative treatment but would revert back
to adopting previous coping mechanisms.
Conclusion: This study illustrates that partially dentate older patients were very satisfied with oral rehabilitation according to a functionally orientated approach. Unfortunately they did not believe that this treatment would currently be made available to them in a primary care setting.

Pharmacogenomics and metastatic colorectal cancer:current knowledge and perspectives

The pharmacogenomics field is crucial for optimizing the selection of which chemotherapy regimen to use according to the patient's genomic profile. Indeed, the individual's inherited genome accounts for a large proportion of the variation in his or her response to chemotherapeutic agents both in terms of efficiency and toxicity. Patients with metastatic disease are more likely to receive different lines of chemotherapy with variable efficacy and experience some related complications. It is therefore critical to tailor the best therapeutic arsenal to improve the efficacy and avoid as much as possible related complications that are susceptible to interrupt the treatment. The pharmacogenomics approach investigates for each drug the implicated metabolic pathway and the potential personal variations in gene function. The aim of this review is to present a clear overview of the most accurate polymorphisms that have been identified as related to drug response in patients with mCRC.

Wide Matching - An Approach to Improving Noise Robustness for Speech Enhancement

It is shown that under certain conditions it is possible to obtain a good speech estimate from noise without requiring noise estimation. We study an implementation of the theory, namely wide matching, for speech enhancement. The new approach performs sentence-wide joint speech segment estimation subject to maximum recognizability to gain noise robustness. Experiments have been conducted to evaluate the new approach with variable noises and SNRs from -5 dB to noise free. It is shown that the new approach, without any estimation of the noise, significantly outperformed conventional methods in the low SNR conditions while retaining comparable performance in the high SNR conditions. It is further suggested that the wide matching and deep learning approaches can be combined towards a highly robust and accurate speech estimator.

Ocular comorbidities among cataract-operated patients in rural China: the caring is hip Study of Cataract Outcomes and Uptake of Services (SCOUTS), report No. 3.

PURPOSE: To determine the prevalence and impact on vision and visual function of ocular comorbidities in a rural Chinese cataract surgical program, and to devise strategies to reduce their associated burden. DESIGN: Cross-sectional cohort study. PARTICIPANTS: Persons undergoing cataract surgery by one of two recently trained local surgeons at a government-run village-level hospital in rural Guangdong between August 8 and December 31, 2005. INTERVENTIONS: Eligible subjects were invited to return for a comprehensive ocular examination and visual function interview 10 to 14 months after surgery. Prevalent ocular comorbid conditions were identified. MAIN OUTCOME MEASURES: Presenting and best-corrected vision, visual function, and treatability of the comorbidity. RESULTS: Of 313 persons operated within the study window, 242 (77%) could be contacted by telephone; study examinations and interviews were performed on 176 (74%). Examined subjects had a mean age of 69.4+/-10.5 years, 116 (66%) were female, and 149 (85%) had been blind (presenting vision < or = 6/60) in the operative eye before surgery. Among unoperated eyes, 89 of 109 (81.7%) had > or =1 ocular comorbidities, whereas for operated eyes the corresponding proportion was 72 of 211 (34.1%). The leading comorbidity among operated eyes was refractive error (43/72 [59.7%]), followed by glaucoma/glaucoma suspect (14/72 [19.4%]), whereas for unoperated eyes, it was cataract (80/92 [87.0%]), followed by refractive error (12/92 [13.0%]). Among operated eyes with comorbidities, 90.3% (65/72) had > or =1 comorbidities that were treatable. In separate models adjusting for age and gender, persons with > or =1 comorbidities in the operated eye had significantly worse presenting vision (P<0.001) than those without such findings, but visual function (P = 0.197) and satisfaction with surgery (P = 0.796) were unassociated with comorbidities. CONCLUSIONS: Ocular comorbidities are highly prevalent among persons undergoing cataract surgery in this rural Asian setting, and their presence is significantly associated with poorer visual outcomes. The fact that the great majority of comorbidities encountered in this program are treatable suggests that strategies to reduce their impact can be successful.

Glycosylation of Vitamin D Binding Protein Reduced in Juvenile Idiopathic Arthritis Patients At Risk of Disease Extension.

Background/Purpose:Juvenile idiopathic arthritis (JIA) comprises a poorly understood group of chronic, childhood onset, autoimmune diseases with variable clinical outcomes. We investigated whether profiling of the synovial fluid (SF) proteome by a fluorescent dye based, two-dimensional gel (DIGE) approach could distinguish the subset of patients in whom inflammation extends to affect a large number of joints, early in the disease process. The post-translational modifications to candidate protein markers were verified by a novel deglycosylation strategy.Methods:SF samples from 57 patients were obtained around time of initial diagnosis of JIA. At 1 year from inclusion patients were categorized according to ILAR criteria as oligoarticular arthritis (n=26), extended oligoarticular (n=8) and polyarticular disease (n=18). SF samples were labeled with Cy dyes and separated by two-dimensional electrophoresis. Multivariate analyses were used to isolate a panel of proteins which distinguish patient subgroups. Proteins were identified using MALDI-TOF mass spectrometry with vitamin D binding protein (VDBP) expression and siaylation further verified by immunohistochemistry, ELISA test and immunoprecipitation. Candidate biomarkers were compared to conventional inflammation measure C-reactive protein (CRP). Sialic acid residues were enzymatically cleaved from immunopurified SF VDBP, enriched by hydrophilic interaction liquid chromatography (HILIC) and analysed by mass spectrometry.Results:Hierarchical clustering based on the expression levels of a set of 23 proteins segregated the extended-to-be oligoarticular from the oligoarticular patients. A cleaved isoform of VDBP, spot 873, is present at significantly reduced levels in the SF of oligoarticular patients at risk of disease extension, relative to other subgroups (p<0.05). Conversely total levels of vitamin D binding protein are elevated in plasma and ROC curves indicate an improved diagnostic sensitivity to detect patients at risk of disease extension, over both spot 873 and CRP levels. Sialysed forms of intact immunopurified VDBP were more prevalent in persistent oligoarticular patient synovial fluids.Conclusion:The data indicate that a subset of the synovial fluid proteome may be used to stratify patients to determine risk of disease extension. Reduced conversion of VDBP to a macrophage activation factor may represent a novel pathway contributing to increased risk of disease extension in JIA patients.

Stress, suporte social, optimismo e saúde em estudantes de enfermagem em ensino clínico

O stress é um processo presente nas vivências do quotidiano dos indivíduos com implicações a nível do seu bem-estar e saúde. No caso específico dos estudantes de Enfermagem, o ensino clínico tem sido identificado como uma componente de formação geradora de elevados níveis de stress. O presente estudo tem como principal objectivo analisar as inter-relações que se estabelecem entre a percepção de situações de stress, saúde, coping, suporte social, auto-estima e optimismo-pessimismo. Pretende-se construir e validar dois instrumentos, um de avaliação das situações indutoras de stress em ensino clínico de Enfermagem (ECE) e outro de avaliação dos sintomas de stress. Outro objectivo consiste em traduzir e adaptar duas escalas, uma de avaliação da auto-estima e outra do optimismo-pessimismo. Pretende-se ainda estudar referidos constructos em função de variáveis sócio-demográficas e de caracterização do ensino clínico realizado. O estudo desenvolvido, de natureza quantitativo, correlacional e transversal, baseou-se numa amostra de 1283 estudantes do Curso de Licenciatura em Enfermagem, de cinco Escolas Superiores de Saúde da Região Centro de Portugal. Foi utilizado um protocolo de investigação constituído por 7 instrumentos: Caracterização sócio-demográfica e do ECE, Escala de Stress em ECE, Escala de Sintomas de Stress, Questionário de Estratégias de Coping, Escala de Satisfação com o Suporte Social, Escala de Auto-Estima e Escala de Optimismo-Pessimismo. Os resultados obtidos sugerem que, ao nível das escalas, tanto as construídas no âmbito deste trabalho, como as traduzidas apresentam validade e valores satisfatórios ao nível da fidelidade, constituindo-se então como instrumentos adequados e úteis para o estudo dos constructos em questão. As situações percebidas como geradoras de maior stress referem-se à avaliação, aspectos pessoais e gestão do tempo e do trabalho. Em termos de sintomas de stress, os mais frequentes são de natureza física e cognitivoemocional. Em termos de estratégias de coping, os estudantes parecem recorrer com mais frequência às estratégias centradas nos problemas. Os estudantes da nossa amostra referem uma maior satisfação a nível do suporte social com a intimidade e evidenciam níveis positivos em termos de autoestima e optimismo. O sexo dos estudantes, o ano de frequência do curso e variáveis de caracterização do ECE exercem um efeito diferencial nas problemáticas em estudo. Consideramos que a identificação das situações indutoras de stress em ECE, bem como a avaliação dos seus efeitos na saúde dos estudantes e a compreensão dos mecanismos de coping podem contribuir para o desenvolvimento de programas de gestão e controlo do stress que os capacitem para transformar os desafios em potenciais situações de desenvolvimento pessoal, social, académico e profissional.

Cuidar da pessoa com esquizofrenia em processo de reabilitação psicossocial

Este ensino clínico permitiu-nos prestar cuidados de enfermagem especializados a 16 homens com esquizofrenia em processo de reabilitação psicossocial. Na sua maioria são: adultos, solteiros, da região sul de Portugal, com uma média de 9 anos de escolaridade, com história de consumo de substâncias (álcool, tabaco, haxixe, cocaína, heroína e anfetaminas), institucionalizados na Casa de Saúde do Telhal (CST) há mais de 11 anos. Todos apresentam diagnósticos de enfermagem das várias dimensões do adoecer, com exceção da dimensão comportamental excitatória, sendo os de maior prevalência: “Conhecimento sobre Processo de doença/Cuidados na doença/Tratamento, Não Demonstrado”; Cognição, Comprometida”; “Processo Social, Alterado”; “Autoestima, Diminuída”. Foram desenvolvidos 4 programas de intervenção: consulta de enfermagem de saúde mental e psiquiatria (CESMP); atelier de estimulação cognitiva (AEC); programa de desenvolvimento de competência intrapessoais, interpessoais e profissionais (PDCIIP); programa de psicoeducação (SABER+). A satisfação global com os programas foi superior a 7 (numa escala de 1 a 10) e os resultados que foram percebidos pela maioria dos reabilitandos situaram-se acima das suas expectativas iniciais. De uma forma geral, todos registaram ganhos: no desempenho cognitivo (em particular os que beneficiaram do AEC); na adaptação psicossocial – nomeadamente ao nível do insight; os reabilitandos que beneficiaram do programa SABER+ melhoraram ainda os comportamentos demonstrados de aceitação do estado de saúde; no bem-estar psicológico – nomeadamente ao nível da autoestima (sobretudo os que beneficiaram da CESMP e/ou do PDCIIP), dos afetos positivos e dos comportamentos de motivação; nos vários domínios da qualidade de vida (QdV) medidos pelo WHOQOL-Bref em particular o domínio ambiental; todos elevaram o seu nível de conhecimentos nos 3 eixos em que que se estruturou o programa de psicoeducação (processo da doença, cuidados na doença, tratamento da doença); na adesão à medicação, sobretudo os que integraram o programa de psicoeducação, contudo todos tendem a necessitar de ajuda parcial para conseguir demonstrar conhecimento no cumprimento do esquema terapêutico e estão envolvidos em treinos supervisionados de preparação e autoadministração; ABSTRACT: This clinical training allowed us to provide skilled nursing care to 16 men with schizophrenia in a psychosocial rehabilitation setting. Most of these individuals are: adults, singles, from the southern region of Portugal, with an average of 9 years of schooling, with a history of substance abuse (alcohol, tobacco, cannabis, cocaine, heroin and amphetamines), institutionalized in Casa de Saúde do Telhal (CST) for over 11 years. We find nursing diagnoses from all of the disease dimensions with the exception of excitatory behavioral dimension, being the most prevalent: "knowledge about disease process / care / treatment, not stated"; cognition, impaired", "social process, impaired”, “self-esteem, decreased". We developed 4 intervention programs: psychiatry and mental health nursing consultation (CESMP); atelier of cognitive stimulation (AEC); intrapersonal, interpersonal and professional competences training (PDCIIP); psychoeducation (SABER+). The overall satisfaction with the programs was above 7 (on a scale of 1 to 10) and the results noticed by most patients were above their initial expectations. All registered nursing results were: in cognitive performance (particularly those who benefited from the AEC); in psychosocial adaptation - especially in terms of insight; patients who benefited from the SABER+ program demonstrated improved further acceptance of their health condition, psychological well-being, particularly in terms of self-esteem (especially those who benefited from the CESMP and/or the PDCIIP), positive affects and motivation; in the different domains of quality of life (QoL) measured by WHOQOL-Bref in particular the environmental domain; every patients raised their level of knowledge in the 3 axes in which the psychoeducational program (SABER+) was structured (disease process, care and treatment); in medication adherence, especially those who benefited of the psychoeducational program, however all the patients tend to need partial help to demonstrate knowledge in meeting the therapeutic regimen and are involved in supervised training programs for preparation and self administration.

O primeiro ensino clínico no percurso formativo do estudante de enfermagem

A formação do estudante de enfermagem em ensino clínico reveste-se de uma importância singular pelo contacto e vivência de situações em contexto, por lhe proporcionar a aquisição, o desenvolvimento e a consolidação de conhecimentos e competências em vários domínios, assim como de socialização com a profissão. O primeiro ensino clínico pelas actividades em contexto com os profissionais de saúde e os utentes é um período de transição particularmente marcante em termos formativos. Nele frequentemente acontece a ruptura nas suas concepções de formação e de aprendizagem, tornando-se num momento de confronto com uma formação que prepara para a incerteza e imprevisibilidade. Nesta investigação pretendemos compreender o que acontece neste período de aprendizagem, partindo da seguinte questão central de investigação: Que significado tem o primeiro ensino clínico no percurso formativo do estudante de enfermagem? O estudo desta questão exigiu o recurso a uma metodologia de natureza qualitativa baseada na estratégia estudo de caso na sua vertente multicasos. Seleccionámos três casos de estudo respectivamente do 1º, do 2º e 3º anos do Curso de Licenciatura em Enfermagem de três planos de estudos de Escolas Superiores de Enfermagem. O caso é constituído por um grupo de estudantes no primeiro ensino clínico hospitalar, enfermeiros e docentes que os orientam. Desenvolvemos uma etnometodologia em que privilegiámos a observação no terreno com participação directa do investigador, recolha documental, entrevistas etnográficas e semi-estruturadas aos vários intervenientes. A análise da informação reunida processou-se pela análise de conteúdo dos dados obtidos num percurso recursivo entre as várias fontes com apoio do programa informático Nvivo 7. Concluímos que o primeiro ensino clínico: é um período de formação estruturante, com forte impacto pela transição que se opera na postura do estudante perante a aprendizagem, pelas propriedades (trans)formativas que as vivências em contexto encerram, independentemente do ano do Curso em que este acontece; a preparação prévia dos estudantes modeliza os domínios da aprendizagem e a profundidade em que ocorre; aprendem de um modo fragmentado sem conseguirem integrar os vários domínios do conhecimento na acção; os estudantes do 1º ano dão mais significado à destreza e rapidez na realização de intervenções prescritas e à aplicação dos princípios teóricos aprendidos; a orientação dos enfermeiros, tutores e docentes é fundamental na mobilização, para a acção, dos conhecimentos teóricos ou na sua aquisição; a vivência das situações em contexto e o ambiente relacional estão entre os factores mais influentes; a prática orientada com atenção individualizada, questionamento, análise e reflexão em díade supervisor-aluno, são fundamentais no desenvolvimento do pensamento crítico; ser supervisor deve ser assumido pelo docente e pelo enfermeiro ou tutor como um trabalho de articulação e proximidade com e no contexto onde o ensino clínico decorre; a resposta adequada às funções específicas de supervisão exige participação activa de equipas de enfermagem mais preparadas e hierarquicamente apoiadas; o docente pelo conhecimento dos estudantes, dos fins e objectivos da formação, pelos desafios e exigência que coloca tem um papel insubstituível. No percurso da investigação novas questões emergiram nomeadamente no que se prende com: os modelos de articulação entre instituições de saúde e escolares; com a formação dos supervisores e; o papel dos pares no início da aprendizagem dos estudantes em contexto clínico.

Avaliação de desempenho dos enfermeiros e percepção de justiça organizacional

As alterações introduzidas pela actual reforma da Administração Pública preconizam uma gestão determinada por objectivos motivando os trabalhadores para um desempenho de qualidade reconhecendo o mérito e a excelência. A avaliação de desempenho dos enfermeiros regulamentada desde 1993, estabelece como princípios orientadores a objectividade, a continuidade, a flexibilidade e a periodicidade, em que a atribuição de uma menção qualitativa resulta da avaliação contínua centrada no conteúdo funcional de cada categoria profissional. A abordagem da justiça organizacional justifica-se, tendo em conta os efeitos das percepções de (in)justiça nas atitudes e comportamentos das pessoas. Essas reacções podem ter efeitos directos e indirectos no funcionamento dos grupos e da organização. Neste contexto, surge este estudo, não experimental, transversal e correlacional de tipo quantitativo, para o qual definimos como objectivos fundamentais: conhecer o nível de satisfação dos enfermeiros com o processo de avaliação de desempenho e variáveis relacionadas; avaliar a percepção de justiça organizacional dos enfermeiros e analisar as possíveis relações entre a satisfação com o processo de avaliação de desempenho e a percepção de justiça organizacional Os dados foram obtidos, através da aplicação de um questionário aos enfermeiros do Hospital em estudo e concluímos que, os enfermeiros avaliam positivamente o nível de satisfação com o processo de avaliação de desempenho, com valores superiores na dimensão comportamental, referente aos aspectos interaccionais do que na dimensão cognitiva, relacionada com os aspectos procedimentais. Os enfermeiros chefes são a categoria profissional com nível mais baixo de satisfação na dimensão referente aos aspectos interaccionais. A análise dos dados referentes ao nível de finalização das diferentes fases do processo de avaliação indicam uma clara descontinuidade dado que, apenas 23,8% dos enfermeiros participa na elaboração das normas e critérios e, inversamente, 97,6% elaboraram o relatório crítico de actividades sendo este o documento de suporte documental que permite a atribuição da menção qualitativa reforçando assim as críticas de burocratização do processo. Relativamente à percepção de justiça organizacional verificamos que a vertente distributiva é a que apresenta valores mais baixos sendo a vertente interaccional aquela em que se verifica valores médios mais elevados. Verificámos existirem correlações positivas e significativas entre as dimensões procedimental e interaccional da percepção de justiça, quer para a dimensão cognitiva quer para a dimensão comportamental do nível de satisfação com a avaliação de desempenho dos enfermeiros. O estudo reforça a convicção de que o processo de avaliação de desempenho deve ser mantido tal como regulamentado, devendo os esforços serem canalizados para corrigir os aspectos referentes à precisão com que o processo avalia o desempenho e o cumprimento de todas as etapas o que só se consegue com a participação reflectida na adesão a um sistema de valores que privilegie a qualidade e definição de indicadores de produtividade e qualidade dos cuidados de enfermagem.
