Background The increase of technological knowledge and methodology has allowed the practice of redirecting epidemiological research, particularly in the field of chronic disease. Although capable of controlling the accumulation of events and constraints imposed by the treatment can lead to a drastic change in quality of life (QoL) of subjects progressed to varying degrees of disability and death. In this perspective the Quality of Life Related to Health (HRQOL) has taken a leading role and its evaluation is indispensable in Medicine. Aim The aims of this study were (1) analyze the importance of HRQOL assessment as a tool for health promotion and a way of measuring the effectiveness of interventions in daily practice in patients with coexisting chronic immune system (PCSI), (2) evaluation of alternative methods for the automated collection of data on HRQOL and development of an electronic interface in sample of 320 patients, (3) creating a database to ascertain the epidemiological profile of PCSI, and identification of socio-economic, demographic and clinical data of these individuals, (4) using the QoL indicator as a predictor in decision treatment and use the preferences of patients. Methods A total of 473 patients with chronic diseases of the immune system, which were applied Graffar Index, SF-36v2, a demographic questionnaire and identification of clinical variables. Results The results of this investigation suggest that the demographic, socio-economic and clinics are associated with significant differences in QoL cumulative and chronic complications associated with different pathologies. The results verified the existence of significant correlations between the different diagnoses, duration of disease and therapy. In general, patients who have chronic diseases of the immune system such as rheumatoid arthritis, lupus, scleroderma, Bechet's disease, Sjögren's syndrome or infection with human immunodeficiency virus 1 or 2 showed a worse QoL than the general population. The derivations of preferences from the SF-36v2 exhibit strong correlations with the preferences measured with the SF-6D. Conclusions This suggests that both the application of the SF-36v2 as the SF-6D can be important sources of preferences to implement measures in economic evaluation in healthcare. HRQL can and should be integrated into immune clinical practice. The translation of graphical results given to the clinician at the beginning of the consultation, favors the rapid analysis of global values of the patient's HRQL. This assessment can be an excellent diagnostic tool to be used routinely in clinical practice or assisting in disease management and therapeutic decision making.

- Development and use of touch-screen computer-assisted self interviewing in Portuguese patients with chronic immune diseases: Evaluation of an electronic version of SF-36v2Publication . Ribeiro, C.; Moreira, L.; Silveira, A.; Silva, I.; Gestal, J.; Vasconcelos, C.Abstract Aim:The major purpose of this study was to evaluate alternative automated methods of collecting data on health related quality of life (HR-QoL). In order to achieve this, we developed a study with the following objectives: (1) to evaluated the feasibility of electronic version in patients with different chronic pathologies of the immune system using Short Form 36version2 (SF-36v2), (2) to evaluate the construct validity of SF-36v2 using the electronic data capture, and (3) to compare electronic version questionnaires with paper questionnaires in terms of patients ´ acceptance, data quality, and reliability. Methods:Out-patients with chronic immune diseases (HIV infection, lupus, scleroderma, rheumatoid arthritis, Behçet and Sjögren), were randomly selected to completed electronic and paper SF- 36v2 (n=50) before consultation in Clinical Immunology Unit, in Hospital Santo António-Centro Hospitalar do Porto (CI-HGSA). Results: There were very high correlations in SF- 36v2 responses (p< .001) between the paper and electronic forms. Internal reliability coefficients (Cronbach’s a) showed good internal consistency for all reported responses in either, computer and paper. There were no missing data in electronic version or paper. About 84% of the patients prefer to use the computer version in future. Conclusion: The electronic HR-QoL assessment is technically possible and it can provide reliable and valid clinically significant information which can either be used in routine care appointments.
- Effectiveness of Psycho-Educational Intervention in HIV Patients' TreatmentPublication . Ribeiro, C.; Sarmento-Castro, R.; Dinis-Ribeiro, M.; Fernandes, L.Adherence to Highly Active Antiretroviral Therapy (HAART) is the main prognostic factor associated with HIV disease progression and death. The aim was to evaluate the effectiveness of a psycho-educational program to promote adherence to HAART in HIV patients. A longitudinal study (n = 102) over 9 months in an Infectious Diseases Hospital was carried out. Adherence to HAART was measured with standardized scales and values of viral load. Two groups were defined: adherents and non-adherents. In the latter, a psycho-educational program was implemented and 6 months later measured adherence to HAART. Knowledge about the infection, CD4 T lymphocytes and HIV-ribonucleic acid values were measured before and after this program. The sample was predominantly male (70%), heterosexual (78%), with a mean age of 49 (SD = 12.7) years, and 48% of participants were not adhering to HAART. After the program, non-adherence decreased to 21.6%. Knowledge about the infection increased from 79 to 97%. A significant increase in CD4 T lymphocytes (mean 540-580) and a decrease in viral load (mean 5411-3052) were observed, the latter of statistical significance. This program seems to be feasible and efficient, improving adherence to HAART.
- Endocardite infecciosa num recém-nascido pré-termoPublication . Ribeiro, C.; Rios, M.; Lopes, L.; Álvares, S.; Proença, E.; Guedes, A.Introdução: A endocardite infecciosa é uma situação rara mas grave no período neonatal. Caso clínico: Os autores descrevem o caso clínico de um recém-nascido, pré-termo de 31 semanas que ao 15º dia de vida apresentou quadro séptico pelo que iniciou antibioticoterapia. Nas hemoculturas efectuadas isolou-se Staphylococus aureus, sensível aos antibióticos prescritos e o cateter epicutâneo-cava introduzido no sexto dia de vida foi nesta altura substituído. Ao 25º dia detectou-se sopro sistólico grau II/VI, tendo o ecocardiograma mostrado imagem sugestiva de vegetação na válvula tricúspide (dimensões-8,5x4mm). Por suspeita de endocardite bacteriana, efectuou tratamento com vancomicina, gentamicina e rifampicina. As hemoculturas posteriores foram estéreis e não se verificou aumento do tamanho da vegetação. Em ambulatório manteve-se clinicamente bem e actualmente, com nove meses de idade corrigida apresenta vegetação de 3x3mm. Conclusão: A suspeita de endocardite bacteriana deve ser considerada nos recém-nascidos com sépsis hospitalar, internados numa Unidade de Cuidados Intensivos, com colocação de cateter venoso central, sobretudo se os agentes envolvidos são o Staphylococcus aureus ou fungos. A base do tratamento é um curso prolongado de antibioticoterapia com um regime bactericida apropriado. Contudo a mortalidade permanece elevada. ABSTRACT Background: Infective endocarditis is a rare but serious illness in neonatal period. Case report: The authors describe the case of a preterm newborn, 31 weeks of gestation who presented at 15th day of life a condition consistent with neonatal sepsis and antibiotic therapy was administered. Staphylococus aureus, sensitive to antibiotics that were prescribed, were detected in blood cultures and the central venous line introduced at 6th day of life was replaced at this point. At 25th day an II/VI grade blowing systolic murmur was heard and the echocardiography showed a suggestive image of vegetation (size-8,5x4mm) in the tricuspid valve. Bacterial endocarditis was suspected and the newborn was treated with vancomycin, gentamicin and rifampicin. The subsequent blood cultures were negative and no increase on vegetation size was observed. In ambulatory, he remained clinically well and actually, with nine months of corrected age, the size of vegetation is 3x3mm. Conclusion: Suspicion of infective endocarditis must be considered in newborns with hospital sepsis in an intensive care setting, with an indwelling catheter, especially if the agents involved are Staphylococcus aureus or fungi. The cornerstone of treatment is a prolonged course of antibiotic treatment with an appropriate bactericidal regimen. However mortality remains high.
- HEALTH-STATE UTILITIES IN CHRONIC IMMUNE DISEASES: PILOT STUDYPublication . Ribeiro, C.; Silveira, A.; Marques, A.; Ribeiro, C.; Santos, I.; Vasconcelos, C.HEALTH-STATE UTILITIES IN CHRONIC IMMUNE DISEASES: PILOT STUDY Claúdia Ribeiro1,2,3, Augusta Silveira4,3, Augusta Marques5, Catarina Ribeiro4, Isabel Santos6,2,3, Carlos Vasconcelos2,3 1UCP, 2HSA/CHP, 3ICBAS/UP, 4UFP, 5HPA e 6HSMF.

Instituto Ciências Biomédicas Abel Salazar, Universidade do Porto (ICBAS/UP), Porto. Universidade Fernando Pessoa (UFP), Porto. Hospital Privado da Arrábida (HPA), Porto. Hospital Santa Maria da Feira (HSMF), Porto. Background Utility scores are used to estimate Quality Adjusted Life Years (QALYs), applied in determining the cost-effectiveness of health care interventions. In studies where no preference based measures are collected, indirect methods have been developed to estimate utilities from clinical instruments. Aim The aim of this study was to evaluate a published method of estimating the Short Form-6D (SF-6D) (preference based) in patients with chronic immune diseases from Unidade de Imunologia Clínica do Hospital de Santo António - Centro Hospitalar do Porto and evaluate the impact of socio demographics economics and clinical characteristics on quality of life (QoL) and potential predictors for QoL improvements. Methods We enrolled 320 patients with chronic immune diseases (104 men and 226 women with a mean age: 45.21; 84 people living with HIV and 236 with chronic autoimmune diseases. All responders to the Portuguese SF-36 version 2.0 questionnaire can be assigned an SF-6D score provided the 11 items used in the SF-6D have been completed using a computerized administration. To assess socioeconomic status, we use the Graffer’s scale, clinical and demographic variables were assessed by a questionnaire specifically designed for the present study. Results The mean utility value was .595. Male, gender, young, single, individuals with high educational attainment level and Graffer’s scale Class high reported higher utility levels. As expected, those who takes therapeutics’ or have a higher length disease reported lower mean utility levels than those who were in a less severe stadium of the disease or without therapeutic. Conclusion This paper provides the first utilities obtained from a populations leave with chronic immune diseases. The preference-based measures used in this study distinguish patient groups with chronic immune diseases’ in terms of socio-demographics characteristics and clinical groups. The normative values can be used economic evaluation and clinical studies as they incorporate patient’s preferences and translate the value attribute to patients´ health state.

- Patient-physician discordance in assessment of adherence to inhaled controller medication: a cross-sectional analysis of two cohortsPublication . Jácome, C.; Pereira, A.; Almeida, R.; Ferreira-Magalhães, Manuel; Couto, M.; Araujo, L.; Pereira, M.; Correia, M.; Loureiro, C.; Catarata, M.; Maia Santos, L.; Pereira, J.; Ramos, B.; Lopes, C.; Mendes, A.; Cidrais Rodrigues, J.; Oliveira, G.; Aguiar, A.; Afonso, I.; Carvalho, J.; Arrobas, A.; Coutinho Costa, J.; Dias, J.; Todo Bom, A.; Azevedo, J.; Ribeiro, C.; Alves, M.; Leiria Pinto, P.; Neuparth, N.; Palhinha, A.; Gaspar Marques, J.; Pinto, N.; Martins, P.; Todo Bom, F.; Alvarenga Santos, M.; Gomes Costa, A.; Silva Neto, A.; Santalha, M.; Lozoya, C.; Santos, N.; Silva, D.; Vasconcelos, M.; Taborda-Barata, L.; Carvalhal, C.; Teixeira, M.; Alves, R.; Moreira, A.; Sofia Pinto, C.; Morais Silva, P.; Alves, C.; Câmara, R.; Coelho, D.; Bordalo, D.; Fernandes, R.; Ferreira, R.; Menezes, F.; Gomes, R.; Calix, M.; Marques, A.; Cardoso, J.; Emiliano, M.; Gerardo, R.; Nunes, C.; Câmara, R.; Ferreira, J.; Carvalho, A.; Freitas, P.; Correia, R.; Fonseca, J.Objective: We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance. Design: Baseline data from two prospective multicentre observational studies. Setting: 29 allergy, pulmonology and paediatric secondary care outpatient clinics in Portugal. Participants: 395 patients (≥13 years old) with persistent asthma. Measures: Data on demographics, patient-physician relationship, upper airway control, asthma control, asthma treatment, forced expiratory volume in one second (FEV1) and healthcare use were collected. Patients and physicians independently assessed adherence to inhaled controller medication during the previous week using a 100 mm Visual Analogue Scale (VAS). Discordance was defined as classification in distinct VAS categories (low 0-50; medium 51-80; high 81-100) or as an absolute difference in VAS scores ≥10 mm. Correlation between patients' and physicians' VAS scores/categories was explored. A multinomial logistic regression identified the predictors of physician overestimation and underestimation. Results: High inhaler adherence was reported both by patients (median (percentile 25 to percentile 75) 85 (65-95) mm; 53% VAS>80) and by physicians (84 (68-95) mm; 53% VAS>80). Correlation between patient and physician VAS scores was moderate (rs=0.580; p<0.001). Discordance occurred in 56% of cases: in 28% physicians overestimated adherence and in 27% underestimated. Low adherence as assessed by the physician (OR=27.35 (9.85 to 75.95)), FEV1 ≥80% (OR=2.59 (1.08 to 6.20)) and a first appointment (OR=5.63 (1.24 to 25.56)) were predictors of underestimation. An uncontrolled asthma (OR=2.33 (1.25 to 4.34)), uncontrolled upper airway disease (OR=2.86 (1.35 to 6.04)) and prescription of short-acting beta-agonists alone (OR=3.05 (1.15 to 8.08)) were associated with overestimation. Medium adherence as assessed by the physician was significantly associated with higher risk of discordance, both for overestimation and underestimation of adherence (OR=14.50 (6.04 to 34.81); OR=2.21 (1.07 to 4.58)), while having a written action plan decreased the likelihood of discordance (OR=0.25 (0.12 to 0.52); OR=0.41 (0.22 to 0.78)) (R2=44%). Conclusion: Although both patients and physicians report high inhaler adherence, discordance occurred in half of cases. Implementation of objective adherence measures and effective communication are needed to improve patient-physician agreement.
- Telemedicina: Situação em PortugalPublication . Álvares, S.; Paiva, M.; Ribeiro, C.; Cruz, V.; Costa, F.; Esteves, J.; Santos, A.; Gonçalves, L.; Pacheco, A.; Miranda, F.; Feiteiro, H.; Ramos, J.; Ricardo, J.; Martinez, A.Introdução: A telemedicina é hoje reconhecida pela OMS como uma ferramenta para melhorar o acesso e a qualidade dos cuidados de saúde. Apesar das vantagens aparentes é uma tecnologia recente e está longe de constituir uma prática de rotina na vida clínica diária. Objectivo: Conhecer a situação actual em Portugal relativamente à telemedicina, nomeadamente: quais as Unidades de Saúde com instalações de telemedicina e áreas em que se desenvolve esta actividade; número de serviços anuais e evolução; dificuldades e obstáculos dos profissionais e Instituições; perspectivas futuras Metodologia: A recolha dos dados foi efectuado através de: inquérito enviados às ARS do Norte, Centro, Lisboa e Vale do Tejo, Alentejo, Algarve e IGIF; entrevista com algumas instituições relativa aos serviços em funcionamento; pesquisa bibliográfica e na Internet Resultados: Dos 6 inquéritos enviados foram recebidos 5, provenientes da ARS Norte, Centro, Lisboa e Vale do Tejo, Algarve e Alentejo. Foram efectuadas entrevistas: H S. João, CHVila Nova de Gaia, CHVale do Sousa e H Pediátrico de Coimbra. Obtivemos informações relativas aos equipamentos instalados e serviços actualmente em funcionamento, em todo o país, destacando- se o funcionamento nas áreas da cardiologia, imagiologia e dermatologia. Não havia registo do número de teleconsultas e transmissão de exames excepto no que se refere à ARS Alentejo. Das dificuldades e obstáculos encontrados salientamos a falta de adesão dos profissionais e instituições; custos do funcionamento do sistema; ausência de definição funcional dos profissionais envolvidos (falta de remuneração dos actos médicos e acumulação de funções); ausência de uma estratégia nacional. Quanto às perspectivas futuras, de um modo geral, os objectivos das ARS incluem: a ligação dos centros de saúde e hospitais, e petrechamento com um equipamento básico de Telemedicina em conformidade com as actividades e tipos de consulta a realizar; o desenvolvimento de projectos no âmbito do INTERREG III. Comentários: O desafio que as organizações tem que enfrentar é a mudança estrutural provocada pela modernização dos processos e métodos de trabalho, «o hospital virtual», e a diluição das barreiras entre os Cuidados Primários e os Diferenciados. A telemedicina exige novas formas de gestão e de medição de desempenho das instituições; esta actividade deve ser equiparada às outras normalmente desenvolvidas nas unidades de saúde. Introduction: Telemedicine is recognized by the WHO as a tool for improvement of access and the quality of health care. However it is not yet a routine procedure in health services. Objective: to assess the utilization of telemedicine in Portugal, namely: health care services equipped with telemedicine, and services provided; annual services and evolution; difficulties and obstacles from professionals and institutions; future trends Methodology: data was obtained through a questionnaire sent to the five Regional Administrations of Health and the Financial Department of Health, interviews with some of the professionals practising Telemedicine and research in the web Results: We received five questionnaires from the Regional Administrations of Health, and collected data from the following Hospitals: S. João, Vila Nova de Gaia, Vale do Sousa e Coimbra Children’s Hospital. We obtained information of the institutions practising telemedicine, and the type of services. Cardiology, radiology and dermatology were the services more frequently provided. The number of teleconsultations or transmitted studies was not registered, except in Alentejo. The more common difficulties to implement this technology were: clinical and providers acceptance; lack of integration into the health care mainstream (the costs of teleconsultations are not reimbursed); equipment and operational costs; absence of a national strategy. Future trends include the equipment of telemedicine stations in Primary and Hospital care and the development of projects in cooperation with Spain (INTERREG III). Comments: Organizations face the challenge of a structural change due to the new technologies (telemedicine and health informatics) and the disappearance of barriers between primary and hospital care. Institutional, organizational and national policies must face new realities to introduce telemedicine into the mainstream of health, including assessment of health outcomes.
