Ethical aspects in the management of the terminally ill patient in the pediatric intensive care unit

OBJECTIVE: To identify the prevalence of management plans and decision-making processes for terminal care patients in pediatric intensive care units. METHODOLOGY: Evidence-based medicine was done by a systematic review using an electronic data base (LILACS, 1982 through 2000) and (MEDLINE, 1966 through 2000). The key words used are listed and age limits (0 to 18 years) were used. RESULTS: One hundred and eighty two articles were found and after selection according to the exclusion/inclusion criteria and objectives 17 relevant papers were identified. The most common decisions found were do-not-resuscitation orders and withdrawal or withholding life support care. The justifications for these were "imminent death" and "unsatisfatory quality of life". CONCLUSION: Care management was based on ethical principles aiming at improving benefits, avoiding harm, and when possible, respecting the autonomy of the terminally ill patient.

Factors that determine the level of care children and adolescents experiencing mental disorders receive

RESUMO: Resumo Uma prestação de serviços de saúde mental para crianças e adolescentes (CAMHS) oportuna, eficaz e baseada na evidência pode evitar incapacidade a longo prazo. No entanto, estes serviços são criticamente sub-financiados em todo o mundo. É um imperativo garantir que este precioso recurso não seja desperdiçado. Os governos e outras partes interessadas relevantes na área da saúde mental precisam de conhecer o estado de saúde mental da população, quais os recursos disponíveis e como melhor utilizar os recursos disponíveis para orientar uma política e decisões efectivas sobre os níveis de serviços. Objetivo: O objetivo deste artigo é explorar o papel da acuidade, gravidade e complexidade na determinação dos cuidados em saúde mental especializados recebidos por crianças e adolescentes que sofrem perturbações mentais. Métodos: Este estudo é exploratório envolvendo uma revisão sistemática da literatura. Foi realizada uma pesquisa com palavras-chave utilizando bases de dados PsychINFO, EMBASE, PubMed e MEDLINE. A literatura cinzenta também foi investigada com um enfoque nas abordagens sistémicas, organizacionais e políticas para a organização e comissionamento de CAMHS. Foram selecionados apenas documentos escritos em Inglês. Três países, Bélgica, Reino Unido e Estados Unidos, todos eles com modelos muito diferentes de organização de CAMHS, foram revistos para investigar de que forma os conceitos de acuidade, gravidade e complexidade foram utilizados na sua concepção de serviços para determinar o nível da assistência prestada. Resultados: Nem a Bélgica, nem o modelo norte-americano de CAMHS organização de serviço parecem estar alinhados com os principais conceitos na determinação do nível de prestação de serviços. O sistema de serviços do Reino Unido de CAMHS está mais estreitamente alinhado com esses conceitos e tem uma alocação de recursos mais equilibrada entre o hospital e a comunidade. O seu ponto fraco está na falta de flexibilidade entre os níveis de serviço e na falta de apoio para com o sector dos cuidados de saúde primários. Conclusões: A variabilidade na alocação de recursos a diferentes níveis especializados de CAMHS (em regime de internamento, ambulatório, e na comunidade) e o modelo diferente de estrutura de serviços entre os países estudados indica uma inconsistência na forma como as crianças e adolescentes que apresentam aos CAMHS são referenciados para os cuidados que recebem. Isto põe em questão se as crianças e adolescentes com perturbações mentais estão a receber o nível e tipo de cuidados concordantes com as suas necessidades. A concepção e o comissionamento de sistemas de CAMHS levam-nos à discussão de uma série de princípios fundamentais que devem ser considerados. O sistema perfeito no entanto, ainda está para ser encontrado. -------------------------------- ABSTRACT: Provision of timely, effective, evidence based mental health services to children and adolescents can prevent long term impairment, but they are critically underfunded across the globe. There is an imperative to ensure this precious resource is not wasted. Governments and other relevant mental health stakeholders need to know the mental health status of the population, what resources are available and how best to use the resources available to guide effective policy and decisions about service levels. Aim: The aim of this paper is to explore the role of acuity, severity and complexity in determining the specialist mental health care that children and adolescents experiencing mental disorders receive. Methods: This study is exploratory involving a systematic scan of the literature. A key word search was conducted using databases PSYCHINFO, EMBASE, PUBMED and MEDLINE. Grey literature was also searched to focus on systemic, organisational and policy approaches to the organisation and commissioning of CAMHS. Only documents written in English were selected. Three countries Belgium, UK and the US all with very different models of service organisation for CAMHS were reviewed to investigate how well the concepts of acuity, severity and complexity were used to determine the level of care delivered in their service design. Findings: Neither the Belgium nor the US model of CAMHS service organisation appear to align with the key concepts driving intensity of level of service provision. The UK CAMHS service system most closely aligns with the concepts. It has a more balanced resource allocation between hospital and community. Its downfall is in its lack of flexibility between service levels and its lack of support for the primary care sector. Conclusions: The variability in resource allocation to different service levels (inpatient, outpatient, community) within specialist CAMHS and the differing model of service structure across countries indicates an inconsistency in how children and adolescents presenting to CAMHS are allocated to the care they receive. This puts into question whether children and adolescent with mental disorders are receiving a level and type of care commensurate with their needs. In commissioning and designing CAMHS systems a number of key principles that should be considered are discussed. The perfect system however, is yet to be found.

Predição precoce de risco de Pré-eclâmpsia na doença hipertensiva e diabetes na gravidez: Papel de fatores angiogénicos

RESUMO: A pré-eclâmpsia tem elevada morbi-mortalidade materna e perinatal. A sua etiologia multi-fatorial tem sido objeto de investigação, não sendo ainda totalmente conhecida. Não se conhece também a razão da diferente suscetibilidade individual e das diferentes expressões da doença. A hipertensão crónica e a diabetes são fatores de risco reconhecidos, e o adiamento da maternidade contribui para que estas duas patologias sejam atualmente mais prevalentes entre as mulheres grávidas. Uma vez que o seu quadro fisiopatológico precede em meses o quadro clínico, tem-se investigado a possibilidade de serem encontrados marcadores precoces e indicadores de risco. Em Portugal, os estudos relativos à hipertensão na gravidez são escassos, bem como a investigação sobre fatores de risco e marcadores para a mesma. No sentido de avaliar possíveis marcadores de risco para o desenvolvimento de préeclâmpsia ou complicações hipertensivas foi colhida, para esta dissertação, uma amostra de 1215 mulheres que frequentaram a consulta de Hipertensão ou de Diabetes na gravidez de um centro terciário, entre 2004 e 2013. Optou-se pela realização de três estudos independentes, abrangendo os dois primeiros um leque temporal de 9 e de 2 anos respetivamente. O primeiro, centrado na hipertensão, pesquisou, em 521 mulheres com hipertensão na presente ou em anterior gravidez, fatores de risco capazes de influenciar a progressão para pré-eclâmpsia. O segundo, direcionado para a diabetes gestacional, considerou uma amostra de 334 grávidas, parte das quais tinha também hipertensão crónica e procurou identificar fatores que contribuíram para o aparecimento de complicações hipertensivas. O terceiro estudo, realizado em 2012 e 2013, em três coortes de grávidas com hipertensão crónica, com diabetes gestacional, e sem estas patologias - procurou avaliar no 1º trimestre o comportamento de dois marcadores placentares obtidos no 1º trimestre - proteína plasmática A associada à gravidez (PAPP-A) e o fator de crescimento placentar (PlGF) - e o seu papel, quer como bio-marcadores isolados, quer em associação aos fatores de risco encontrados nos anteriores estudos, na construção de um modelo preditivo de préeclâmpsia. No primeiro estudo, a nuliparidade, a hipertensão gestacional, a fluxometria das artérias uterinas com IP superiores ao P95 entre as 20-22 semanas e a existência de restrição de crescimento fetal, foram os fatores que contribuíram para a construção de um modelo preditivo de pré-eclâmpsia. No segundo estudo, a coexistência de diabetes e hipertensão crónica agravou o prognóstico, associando-se as complicações hipertensivas à multiparidade, obesidade, idade materna e etnia negra. No terceiro estudo verificou-se uma redução da PlGf e da PAPP-A no 1º trimestre nas duas primeiras coortes, comparativamente à coorte sem patologia; na análise separada de cada coorte, quando se verificaram complicações hipertensivas ou pré-eclâmpsia, as concentrações de PlGf e PAPP-A também foram inferiores. Contudo, na elaboração de um modelo preditivo de pré-eclâmpsia, em conjunto com marcadores encontrados, apenas a PlGf pode ser integrada no modelo preditivo, o que se verificou na coorte com hipertensão crónica. Os marcadores bioquímicos em estudo tiveram valores inferiores nas coortes com patologia hipertensiva, demonstrando uma deficiente produção destas proteínas placentares nestas situações, podendo ser importante a sua pesquisa. Contudo, neste estudo, apenas na coorte de hipertensão crónica a PlGf teve participação como fator de risco, na construção de um modelo preditivo de pré-eclâmpsia.--------------------------------------------------------------------------------------------------ABSTRACT: Preeclampsia is associated with a great maternal and perinatal morbimortality. Its multifactorial etiology has been under investigation and is still insufficiently understood. The reason why there are differences in individual susceptibility and differences in expressions of the disease is still unknown. Chronic hypertension and diabetes are known risk factors for preeclampsia and maternity delay contributes to the great prevalence of these pathologies among pregnant women. As the physiopathological signs antedate by months the clinical course of the disease, early risk factors and biological markers are object of clinical research. In Portugal, scarce clinical studies were devoted to hypertension in pregnancy and to risk factors and markers of this pathology. This dissertation inquires 1215 pregnant women who were treated for hypertension or diabetes in a tertiary care center between 2004 and 2013, in order to find risk markers for hypertensive complications or preeclampsia. We conducted three independent studies for this purpose. In the first one we investigated which risk factors could influence the progression to preeclampsia in 521 pregnant women with present or past history of hypertension. The second one was conducted to find what factors were associated to hypertensive complications, with a sample of 334 pregnant women with gestational diabetes, some also with chronic hypertension, addressing the identification of the factors contributing to hypertensive complications. The third study was conducted between 2012 and 2013 with three cohorts of pregnant women, with chronic hypertension, gestational diabetes, and in the third one, pregnant women had a low risk pregnancy. The objective of the study was to evaluate the behavior of two placental markers – PAPP-A and PlGf – obtained in the first trimester, and the role of these markers as isolated biomarkers or in association with other risk factors, in order to define a predictive model of early preeclampsia. In the first study, nuliparity, gestational hypertension, uterine arteries doppler with PI above P95 between 20-22 weeks of gestation and the presence of fetal growth restriction were the markers involved in a predictive model for preeclampsia. In the second study the cohort with the coexistence of diabetes and hypertension had registered worse result and hypertensive complications were associated to multiparity, obesity, maternal age and black ethnicity. In the third study there was a reduction of the PlGf and a PAPP-A concentration for the first trimester in the two first cohorts comparatively to the low risk cohort; the separate analysis of each cohort showed that plGf and PAPP-A concentrations were reduced when hypertensive complications appeared. However, when trying to find a preeclampsia predictive model, only plGf gave significant results for being considered in the model and this was only possible in the chronic hypertension cohort. The biochemical markers investigated in this study were reduced in the cohorts when high blood pressure complications occurred, showing a defective production of these placenta proteins, and suggesting that they should be investigated as first trimester biomarkers. Nevertheless, for this research, in the cohort of chronic hypertension only PlGf had a significant result, when multivariate analysis of all the risk factors was considered for the construction of a preeclampsia predictive model.

Aggregating community resources of care and assistance services for the elderly population

Changes in population age structure are a major concern and represent a priority in the agendas and policies of the developed world, which are demanding for renewed models of social and healthcare as well as assistance services to the elderly population. Studies indicate that as far as possible these types of services should desirably be provided at the user’s home, and that ICT-based solutions can have tremendous impact on the delivery of new services. This paper highlight and discusses some of the main results of a project undertaken in a Portuguese Municipality that demonstrates the potential contribution of an e-Marketplace of care and assistance services to the well-being of elderly people. Studies undertaken allowed identifying the main services that should be provided by such e-Marketplace (termed GuiMarket), the relevance that the population grant to this platform and, conversely, the fact that the Digital Divide phenomena influences the potential utilization of this project (and alike projects). The findings support that there is a strong relation between age and qualifications, and between access to ICT and the intended use of GuiMarket.

Child abuse monitor system model: a health care critical knowledge monitor system

The Childhood protection is a subject with high value for the society, but, the Child Abuse cases are difficult to identify. The process from suspicious to accusation is very difficult to achieve. It must configure very strong evidences. Typically, Health Care services deal with these cases from the beginning where there are evidences based on the diagnosis, but they aren’t enough to promote the accusation. Besides that, this subject it’s highly sensitive because there are legal aspects to deal with such as: the patient privacy, paternity issues, medical confidentiality, among others. We propose a Child Abuses critical knowledge monitor system model that addresses this problem. This decision support system is implemented with a multiple scientific domains: to capture of tokens from clinical documents from multiple sources; a topic model approach to identify the topics of the documents; knowledge management through the use of ontologies to support the critical knowledge sensibility concepts and relations such as: symptoms, behaviors, among other evidences in order to match with the topics inferred from the clinical documents and then alert and log when clinical evidences are present. Based on these alerts clinical personnel could analyze the situation and take the appropriate procedures.

Step towards multiplatform framework for supporting pediatric and neonatology care unit decision process

Children are an especially vulnerable population, particularly in respect to drug administration. It is estimated that neonatal and pediatric patients are at least three times more vulnerable to damage due to adverse events and medication errors than adults are. With the development of this framework, it is intended the provision of a Clinical Decision Support System based on a prototype already tested in a real environment. The framework will include features such as preparation of Total Parenteral Nutrition prescriptions, table pediatric and neonatal emergency drugs, medical scales of morbidity and mortality, anthropometry percentiles (weight, length/height, head circumference and BMI), utilities for supporting medical decision on the treatment of neonatal jaundice and anemia and support for technical procedures and other calculators and widespread use tools. The solution in development means an extension of INTCare project. The main goal is to provide an approach to get the functionality at all times of clinical practice and outside the hospital environment for dissemination, education and simulation of hypothetical situations. The aim is also to develop an area for the study and analysis of information and extraction of knowledge from the data collected by the use of the system. This paper presents the architecture, their requirements and functionalities and a SWOT analysis of the solution proposed.

Step towards a patient timeline in intensive care units

In Intensive Medicine, the presentation of medical information is done in many ways, depending on the type of data collected and stored. The way in which the information is presented can make it difficult for intensivists to quickly understand the patient's condition. When there is the need to cross between several types of clinical data sources the situation is even worse. This research seeks to explore a new way of presenting information about patients, based on the timeframe in which events occur. By developing an interactive Patient Timeline, intensivists will have access to a new environment in real-time where they can consult the patient clinical history and the data collected until the moment. The medical history will be available from the moment in which patients is admitted in the ICU until discharge, allowing intensivist to examine data regarding vital signs, medication, exams, among others. This timeline also intends to, through the use of information and models produced by the INTCare system, combine several clinical data in order to help diagnose the future patients’ conditions. This platform will help intensivists to make more accurate decision. This paper presents the first approach of the solution designed

Intelligent decision support to predict patient barotrauma risk in intensive care units

The occurrence of Barotrauma is identified as a major concern for health professionals, since it can be fatal for patients. In order to support the decision process and to predict the risk of occurring barotrauma Data Mining models were induced. Based on this principle, the present study addresses the Data Mining process aiming to provide hourly probability of a patient has Barotrauma. The process of discovering implicit knowledge in data collected from Intensive Care Units patientswas achieved through the standard process Cross Industry Standard Process for Data Mining. With the goal of making predictions according to the classification approach they several DM techniques were selected: Decision Trees, Naive Bayes and Support Vector Machine. The study was focused on identifying the validity and viability to predict a composite variable. To predict the Barotrauma two classes were created: “risk” and “no risk”. Such target come from combining two variables: Plateau Pressure and PCO2. The best models presented a sensitivity between 96.19% and 100%. In terms of accuracy the values varied between 87.5% and 100%. This study and the achieved results demonstrated the feasibility of predicting the risk of a patient having Barotrauma by presenting the probability associated.

Quality of institutional care and early childhood development

Institutional rearing adversely affects children’s development, but the extent to which specific characteristics of the institutional context and the quality of care provided contribute to problematic development remains unclear. In this study, 72 preschoolers institutionalised for at least 6 months were evaluated by their caregiver using the Child Behavior Checklist and the Disturbances of Attachment Interview. Distal and proximate indices of institutional caregiving quality were assessed using both staff reports and direct observation. Results revealed that greater caregiver sensitivity predicted reduced indiscriminate behaviour and secure-base distortions. A closer relationship with the caregiver predicted reduced inhibited attachment behaviour. Emotional and behavioural problems proved unrelated to caregiving quality. Results are discussed in terms of (non)-shared caregiving factors that influence institutionalised children’s development.

Alcohol-dependent patients receiving specialised outpatient care: an overview of gender issues

OBJECTIVE: The objective of the present study, with focus on gender, was aimed at evaluating alcohol-dependent individual in terms of socio-demographic variables related to alcohol consumption and therapeutic interventions. METHODS: This is a retrospective cross-sectional study of 1,051 patients (833 men and 218 women), with diagnosis of alcohol dependence syndrome, according to ICD-10 criteria, who had sought treatment for the first time at a specialised health centre between 2000 and 2006. RESULTS: The results showed that women, compared to men, are more likely to be unemployed and without partner, in addition to having higher educational level, latter age of alcohol initiation, needing less outpatient alcohol detoxification program, consuming more fermented beverage, presenting less psychiatric comorbidities, and using less coadjutant medications during treatment. CONCLUSION: We can state that some peculiarities exist permeating both gender and alcohol consumption. A further focus on the characteristics of each population is needed to facilitate the adequate use of therapeutic interventions according to gender specificities.

Quality of life assessment of patients with schizophrenic spectrum disorders from Psychosocial Care Centers

OBJECTIVE: Assessing the quality of life and the clinical and social-demographic factors associated in schizophrenic spectrum patients (ICD-10 F20-F29) attending CAPS at the programmatic area 3.0. METHODS: A cross-sectional study was carried out in a sample of schizophrenic spectrum patients who have been enrolled in 2008 in CAPS in programmatic area (AP) 3 at Rio de Janeiro city, using MINIPLUS to assess schizophrenia spectrum disorder and use of psychoactive substances, Positive and Negative Symptoms Scale (PANSS) to assess psychiatric symptoms and Quality of Life Scale (QLS-BR) to assess the quality of life. RESULTS: Seventy nine patients were included, of whom 74 (93.7%) presented some impairment in quality of life. The most frequently affected area was occupational performance. Variables that showed a significant association with severe impairment of quality of life were: marital status, race, occupation, who patients lived with, homelessness, having children, previous psychiatric hospitalization, negative symptoms and symptoms designated as not applicable (being characterized by a lack of typical positive and negative symptoms). CONCLUSION: The knowledge of these factors should be crucial to implement health policies and psychosocial rehabilitation programs focused on improving the quality of life of these patients.

Psychiatric morbidity and quality of life of primary care attenders in two cities in Brazil

Objective: To identify the associations among quality of life (QoL), social determinants and psychological distress in primary care in two cities in Brazil. Methods: A cross-sectional study with 1,466 patients from 2009 to 2010. The statistical analysis used the t-test to compare the variables of interest to the study. Results: The prevalence of Common Mental Disorders (CMD3), severe forms of Common Mental Disorders (CMD5), anxiety and depression were 20.5%, 32%, 37% and 25.1% respectively. Thes presence of psychological distress is associated with worse QoL among the patients studied, especially those older than 40 years of age. In cases of CMD3, those with higher income and educational levels presented higher QoL in the psychical and psychological domains. For the cases of probable anxiety, those with higher educational levels presented lower scores on the physical and social relationship scores. Conclusion: Psychological distress can be associated with a worse QoL among those studied and can be influenced by socioeconomic conditions. Therefore, it is important to structure patient-centered help, which should also include patients’ social contexts.
