Maturity models in the hospital information systems management initial research

Os modelos de maturidade são instrumentos facilitadores da gestão das organizações, incluindo a gestão da sua função sistemas de informação, não sendo exceção as organizações hospitalares. Neste artigo apresenta-se uma investigação inicial que visa o desenvolvimento de um abrangente modelo de maturidade para a gestão dos sistemas de informação hospitalares. O desenvolvimento deste modelo justifica-se porque os modelos de maturidade atuais no domínio da gestão dos sistemas informação hospitalares ainda se encontram numa fase embrionária de desenvolvimento, sobretudo porque são pouco detalhados, não disponibilizam ferramentas para determinação da maturidade e não apresentam as características dos estágios de maturidade estruturadas por diferentes fatores de influência.

Microsporidiosis in a Brazilian University Hospital: case report

This is the report on a patient with chronic diarrhea caused by microsporidia. He is married, infected with HIV and has low CD4 cell count. The diagnosis was established through stool parasite search using concentration methods and Gram - chromotrope staining technique. Ileum biopsy was also performed in this case. The etiological diagnosis may be established in a clinical laboratory, by chromotrope staining technique in routine microscopic examination of stool specimens.

Prevenção e Controlo do Risco de Exposição Ocupacional à Tuberculose Pulmonar no CHL/Hospital de S. José

A Tuberculose é uma doença altamente contagiosa que atinge sobretudo idosos e pessoas com maior vulnerabilidade, embora afecte também a população activa, em particular os mais expostos como os profissionais de saúde. A sua transmissão é potenciada por factores demográficos, pela urbanização, pelo aparecimento de formas resistentes à medicação habitual e pela associação à infecção por VIH. Apresenta-se o modelo, estratégia, métodos e resultados da intervenção de prevenção do risco profissional de Tuberculose no CHL/Hospital S. José desenvolvida pelo Serviço de Saúde Ocupacional (SSO). O SSO é constituído por equipa multiprofissional composta por Medicina do Trabalho, Ergonomia, Higiene e Toxicologia, Psicologia e Segurança do Trabalho, e inclui uma componente técnica orientada para os problemas de saúde no trabalho e a prevenção dos riscos ocupacionais, e uma componente clínica vocacionada para os problemas de saúde individual e o atendimento na doença aguda e crónica, assegurando cuidados de saúde personalizados e integrados (primários, secundários e terciários), com ênfase na prevenção primária e promoção da saúde no trabalho. A equipa de Enfermagem intervém na mediação e personalização dos cuidados da Medicina do Trabalho e da área clínica, interagindo com a equipa técnica no que se refere aos problemas da saúde no trabalho. No Hospital trabalham cerca de 2500 profissionais (68%do sexo feminino), dos quais os grupos profissionais mais representativos correspondem à enfermagem (29%), auxiliares (25,8%) e médicos (19,5%), apresentando diferentes factores de vulnerabilidade, predisposição e doença associados a hábitos, comportamentos e estilos de vida, e a riscos particulares das tarefas da sua actividade. O SSO iniciou a intervenção sistemática de prevenção e controlo do risco de Tuberculose nos profissionais do Hospital em Abril de 1996 com a disponibilização do rastreio activo, em colaboração com o Centro de Diagnóstico Pneumológico da Praça do Chile, o qual representa, até ao presente, a maior adesão registada em hospitais do país. Reflecte-se o nível de risco de exposição ocupacional dos profissionais à tuberculose, particularidades de risco dos cenários e adequação da protecção individual, isolamento e ventilação; o rastreio activo (Mantoux, Rx tórax) inicial, periódico conforme o nível de risco, após exposição e em profissionais com vulnerabilidade – Mantoux negativos, imunocomprometidos (VIH, corticoterapia, imunossupressão, insuficiência renal, …); a informação personalizada aos profissionais, formação individual e de grupo, em sala e no local de trabalho; e os resultados (taxa de Tuberculose latente, taxa de viragem tuberculínica, quimioprofilaxia, Tuberculoses profissionais).

No Fate But What We Make: a Case of Full Recovery After Out-of-Hospital Cardiac Arrest

An 80 years old man suffered a cardiac arrest shortly after arrival to his local health department. Basic Life Support was started promptly and nine minutes later, on evaluation by an Advanced Life Support team, the victim was defibrillated with a 200J shock. When orotracheal intubation was attempted, masseter muscle contraction was noticed: on reevaluation, the victim had pulse and spontaneous breathing.Thirty minutes later, the patient had been transferred to an emergency department. As he complained of chest pain, the ECG showed a ST segment depression in leads V4 to V6 and laboratory tests showed cardiac troponine I slightly elevated. A coronary angiography was performed urgently: significant left main plus three vessel coronary artery disease was disclosed.Eighteen hours after the cardiac arrest, a quadruple coronary artery bypass grafting operation was undertaken. During surgery, a fresh thrombus was removed from the middle left anterior descendent artery. Post-operative course was uneventful and the patient was discharged seven days after the procedure. Twenty four months later, he remains asymptomatic.In this case, the immediate call for the Advanced Life Support team, prompt basic life support and the successful defibrillation, altogether, contributed for the full recovery. Furthermore, the swiftness in the detection and treatment of the acute reversible cause (myocardial ischemia in this case) was crucial for long-term prognosis.

Candiduria in a public hospital of São Paulo (1999-2004): characteristics of the yeast isolates

The study involved 100 yeast isolates, obtained from urine samples provided by a Public Pediatric Hospital of São Paulo, Brazil, from 1999 to 2004. The most frequent species was Candida albicans, followed by C. tropicalis, C. glabrata and C. parapsilosis. In regard to virulence, 97% of the isolates showed index 3 for proteinase and 63% index 2 for phospholipase. The most frequent killer biotypes were 511 and 888.

A comparison of the immune parameters of dogs infected with visceral leishmaniasis using Western blot and neutralization techniques

The Western blot technique was used to demonstrate the presence of antibodies in the blood of dogs that presented canine visceral leishmaniasis. This technique was used against some specific molecules present in the lysate of the promastigote form of Leshmania chagasi.Through the association of the results of the Western blot technique with the morphological alterations seen as a result of the serum neutralization technique performed in McCoy cells (which mimetizes the macrophage) it was possible to observe the role of some molecules of great relevance in determining the disease in symptomatic dogs as well as that of some other molecules associated with asymptomatic infected dogs that may become transmitters as well as differentiating them as asymptomatic resistant dogs. In the sera analyses carried out during the immunobloting a variation of 9 to 27 immunoreacting bands was observed, which were then compared using Dice's similarity coefficient. In the dendrogram constructed on the basis of the coefficient, 50% similarity was observed among the total number of reagent bands with the promastigote lysate, thus creating five groups. The main difference observed related to the clinical condition of the dogs: symptomatic and asymptomatic dogs were found in separate groups. The asymptomatic group of dogs was distributed in two different places in the dendrogram because they presented two different behavior patterns regarding the cellular morphology in the serum neutralization reaction: the presence or absence of cellular lysis. According to this analysis it is possible to evaluate the immune status and associate it with specific markers observed in the reaction found in the Western blot strips.

Novos Padrões versus Velhos Hábitos de Prescrição de Albumina num Hospital Central

O presente estudo teve como objectivo aferir a adequação da prescrição de albumina humana num hospital central à evidência científica nesta área actualmente disponível. O estudo foi retrospectivo e analisou os pedidos de albumina aos serviços farmacêuticos entre Setembro de 2007 e Agosto de 2008. Analisadas 761 requisições de 619 doentes com idade média de 58,1 +/- 14,7 anos, 510 (77%) dos quais do sexo masculino. Foram avaliados parâmetros analíticos globais (proteínas totais, albumina sérica, creatinina e INR) à data da requisição de albumina, grandes grupos nosológicos e os motivos de prescrição. Dos 556.831 frascos de albumina requisitados, foram efectivamente administrados 5.033 (0,9%). Os doentes com patologia hepática foram o grupo nosológico mais representado (60%). Verificou-se que 36% dos pedidos correspondiam aos critérios científicos com suporte de evidência, sendo a hipoalbuminémia o motivo mais frequente de pedido (53%). Concluímos que é necessário um maior cuidado no fundamento dos pedidos de albumina, de forma a adequá-los à evidência científica. Normas restritivas dos serviços farmacêuticos para o fornecimento de albumina encontram-se justificadas.

Candida bloodstream infection: data from a teaching hospital in Mato Grosso do Sul, Brazil

The incidence of Candida bloodstream infection has increased over the past years. In the Center-West region of Brazil, data on candidemia are scarce. This paper reports a retrospective analysis of 96 cases of Candida bloodstream infection at a Brazilian tertiary-care teaching hospital in the state of Mato Grosso do Sul, from January 1998 to December 2006. Demographic, clinical and laboratory data were collected from medical records and from the hospital's laboratory database. Patients' ages ranged from three days to 92 years, with 53 (55.2%) adults and 43 (44.8%) children. Of the latter, 25 (58.1%) were newborns. The risk conditions most often found were: long period of hospitalization, utilization of venous central catheter, and previous use of antibiotics. Fifty-eight (60.4%) patients died during the hospitalization period and eight (13.7%) of them died 30 days after the diagnosis of candidemia. Candida albicans (45.8%) was the most prevalent species, followed by C. parapsilosis (34.4%), C. tropicalis (14.6%) and C. glabrata (5.2%). This is the first report of Candida bloodstream infection in the state of Mato Grosso do Sul and it highlights the importance of considering the possibility of invasive Candida infection in patients exposed to risk factors, particularly among neonates and the elderly.

Epidemiological and ecological aspects related to malaria in the area of influence of the lake at Porto Primavera dam, in western São Paulo State, Brazil

A study was carried out in the area of influence of the Porto Primavera Hydroelectric Power Station, in western São Paulo State, to investigate ecological and epidemiological aspects of malaria in the area and monitor the profile of the anopheline populations following the environmental changes brought about by the construction of the lake. Mosquitoes captured were analyzed by standardized indicator species analysis (ISA) before and during different flooding phases (253 m and 257 m elevations). The local human population was studied by means of parasitological (thin/thick blood smears), molecular (PCR) and serological tests. Serological tests consisted of Enzyme Linked Immunosorbent Assay (ELISA) with synthetic peptides of the circumsporozoite protein (CSP) from classic Plasmodium vivax, P. vivax variants (VK247 and "vivax-like"), P. malariae and P. falciparum and Indirect Immunofluorescence Assay (IFA) with asexual forms of P. vivax, P. malariae and P. falciparum. The results of the entomological survey indicated that, although the Anopheles darlingi population increased after the flooding, the population density remained very low. No malaria, parasite infection or DNA was detected in the inhabitants of the study area. However, there was a low frequency of antibodies against asexual forms and a significant prevalence of antibodies against P. vivax, P. vivax variants, P. falciparum and P. malariae; the presence of these antibodies may result from recent or less recent contact with human or simian Plasmodium (a parallel study in the same area revealed the existence of a sylvatic cycle). Nevertheless, these results suggest that, as in other places where malaria is present and potential vectors circulate, the local epidemiological conditions observed could potentially support the transmission of malaria in Porto Primavera Lake if infected individuals are introduced in sufficient numbers. Further studies are required to elucidate the phenomena described in this paper.

Acute postsurgical suppurative parotitis: current prevalence at Hospital das Clínicas, São Paulo University Medical School

Postsurgical acute suppurative parotitis is a bacterial gland infection that occurs from a few days up to some weeks after abdominal surgical procedures. In this study, the authors analyze the prevalence of this complication in Hospital das Clínicas/São Paulo University Medical School by prospectively reviewing the charts of patients who underwent surgeries performed by the gastroenterological and general surgery staff from 1980 to 2005. Diagnosis of parotitis or sialoadenitis was analyzed. Sialolithiasis and chronic parotitis previous to hospitalization were exclusion criteria. In a total of 100,679 surgeries, 256 patients were diagnosed with parotitis or sialoadenitis. Nevertheless, only three cases of acute postsurgical suppurative parotitis associated with the surgery were identified giving an incidence of 0.0028%. All patients presented with risk factors such as malnutrition, immunosuppression, prolonged immobilization and dehydration. In the past, acute postsurgical suppurative parotitis was a relatively common complication after major abdominal surgeries. Its incidence decreased as a consequence of the improvement of perioperative antibiotic therapy and postoperative support. In spite of the current low incidence, we believe it is important to identify risks and diagnose as quick as possible, in order to introduce prompt and appropriate therapeutic measures and avoid potentially fatal complications with the evolution of the disease.

Deficiência Mental: Casuística da Unidade de Desenvolvimento do Hospital de Dona Estefânia

Segundo a DSM IV a Deficiência Mental (DM) define-se como o funcionamento intelectual global inferior à média (QI < 70) associado a perturbações do comportamento adaptativo com início antes dos 18 anos. Procurou-se caracterizar retrospectivamente a população de crianças com DM observadas no Centro de Desenvolvimento do Hospital de Dona Estefânia (CDHDE), entre Janeiro 2005 e Junho 2007. Foram avaliados os dados epidemiológicos, gravidade, etiologia, co-morbilidade e intervenção proposta. Do total de 232 processos clínicos observados, 185 apresentavam DM. Classificaram-se em DM ligeira 112 (61%), DM moderada 54 (29%), DM grave 17 (9%) e profunda 2 (1%). Foram definidas etiologias em 86 crianças (46%) sendo a taxa de diagnóstico mais elevada na DM de maior gravidade. Observou-se uma elevada variabilidade de etiologias: as mais frequentemente encontradas foram as doenças genéticas, prematuridade e patologia associada. Foi detectada co-morbilidade em 123 crianças (66%), sendo a mais frequente as do foro oftalmológico (57 crianças, 46%). Foram propostas e sinalizadas para apoio a totalidade das crianças com DM, 47% em intervenção precoce e 58% em educação especial, das quais 5% usufruiram, por curto período, do apoio simultaneo de educadora de Intervenção Precoce e de docente do Ensino Especial, durante o período inicial de integração em jardim de infância. Observou-se um predomínio do sexo masculino. Foi efectuada caracterização clínica e funcional das crianças seguidas no CDHDE com o diagnóstico de DM e encontraram-se semelhanças entre os dados presentes e os descritos na literatura. Contudo alguns dados diferem de outras casuísticas decorrente, muito provavelmente decorrente da heterogeneidade da população estudada, quer do ponto de vista etiológico, quer no referente aos grupos etários, provavelmente condicionada, pela política assistencial.
