Sociální práce s lidmi se schizofrénií / Social Work with People with Schizophrenia

Mládková, Marcela January 2012 (has links)
Diploma thesis "Social Work with People with Schizophrenia" deals with global life - sustaining situation of people who have in some part of their lives the experience with schizophrenia or with some similar disease from the same range. Theoretical part of this work presents basic facts about schizophrenia - about the course of this disease and about the treatment possibilities and also tries to outline - how are the possibilities of "successive care" it means the care which people with schizophrenia can find after their hospitalization after they enter the psychiatric care and start to use medicine and start attending psychotherapy. One of the aims of this thesis is to map how the real possibilities are for the people with schizophrenia after they return after their psychotic episode to "regular" life and try to live normally how to work, start relationships, engage in their hobbies etc.

Caroline Padovan Prado 29 February 2012 (has links)
Os objetivos deste estudo foram: caracterizar os idosos internados na Clínica Médica de um Hospital Geral Terciário, do interior paulista, segundo: variáveis sociodemográficas, estilo de vida, condições de saúde, acesso aos serviços de saúde e rede de apoio familiar e social; identificar a capacidade cognitiva, a capacidade funcional e a presença de sintomas de depressão desses idosos; verificar a existência de associação entre a variável queda com as variáveis faixa etária, sexo, déficit cognitivo, uso de óculos, hábito de beber e presença de sintomas de depressão; e verificar a existência de associação entre a variável déficit cognitivo com as variáveis faixa etária, sexo e estado conjugal. Trata-se de um estudo não experimental, descritivo e transversal. Realizado com idosos, internados na Clínica Médica, do referido hospital, no período de abril a julho de 2011. Para a coleta de dados, utilizaram-se o Miniexame do Estado Mental (MEEM), uma readaptação do Older Americans Resources and Services (OARS) e a Escala de Depressão Geriátrica (EDG). Foram estudados 105 idosos, média de idade de 73,8 anos (s=8,9); 59,0% eram homens; 62,9% moravam com esposo(a) ou companheiro(a); 47,6% estudaram de um a quatro anos; 90,5% eram aposentados. Quanto ao estilo de vida, 80,0% não fumavam atualmente; 71,4% consumiam bebida alcoólica; 66,7% não praticavam atividade física. Com relação à saúde, 72,4% a autoavaliaram como \"Boa\"; 56,2% tinham diagnóstico de hipertensão arterial e 22,9 de fibrilação atrial; para 78,1% todos os medicamentos eram receitados pelo médico; 91,4% avaliaram sua visão como \"Boa\"; 23,9% faziam uso dos óculos; 39,0% caíram nos últimos 12 meses; 23,8% caíram de três a quatro vezes. Quanto ao acesso aos serviços de saúde e à rede de apoio familiar e social, 96,2% utilizavam Hospital Público e estavam satisfeitos; para 45,7%, o esposo(a) ou companheiro(a) foi a primeira menção para cuidador na presença de incapacidades. Na avaliação cognitiva pelo MEEM, 34,3% apresentaram cognição comprometida. Quanto ao desempenho para as AVDs, no momento da admissão, 81,9% apresentavam algum grau de dificuldade nas ABVDs e 86,7% nas AIVDs; durante a hospitalização, 89,5% e, no momento da alta, 84,8% realizavam as atividades básicas com dificuldades. Os sintomas de depressão estiveram presentes em 54,3% dos idosos, média de 5,4 (s=2,5). Observou-se associação entre a presença de quedas e o uso de óculos (p<0,01) e entre a presença de déficit cognitivo e a faixa etária (p=0,04). A identificação do perfil e das necessidades dos idosos hospitalizados pode subsidiar o planejamento da assistência, com enfoque multiprofissional. / The objectives of this study were to characterize elderly individuals hospitalized in the medical clinic of a tertiary general hospital in the interior of São Paulo, Brazil according to the following socio-demographic variables: lifestyle, health conditions, access to health services and family and social support network; to identify cognitive and functional capacity and depression symptoms among these patients; to verify potential association between the variable \'fall\' with age, gender, cognitive deficit, use of glasses, alcohol consumption, and depression symptoms; and also to verify potential association between the variable \'cognitive deficit\' with age, gender and marital status. This non-experimental, descriptive and cross-sectional study addressed elderly individuals hospitalized in the medical clinic of the mentioned hospital from April to July 2011. The Mini-Mental State Examination (MMSE), a readaptation of Older Americans Resources and Services (OARS), and the Geriatric Depression Scale (GDS) were used to collect data. A total of 105 elderly individuals aged 73.8 years old in average (s=8.9) participated in the study; 59.0% were men; 62.9% lived with spouses or partners; 47.6% studied from one to four years; 90.5% were retired. In relation to lifestyle, 80.0% did not smoke at the time; 71.4% consumed alcohol; 66.7% did not exercise. In relation to their health condition, 72.4% reported it was \"good\"; 56.2% had hypertension, and 22.9 had atrial fibrillation; 78.1% had all medications prescribed by a physician; 91.4% reported their eyesight was \"good\"; 23.9% wore glasses; 39,0% fell in the last 12 months; 23.8% fell from three to four times. In regard to access to health services and family and social support network, 96.2% used public hospitals and were satisfied; 45.7% reported the spouse or partner would be the primary caregiver in case of disability. A total of 34.3% presented compromised cognition in the MMSE cognitive evaluation. In relation to the performance of ADLs at the time of admission, 81.9% presented some level of difficulty in BADLs and 86.7% in IADLs; 89.5% and 84.8% performed basic activities with difficulty during hospitalization and at time of discharge, respectively. Depression symptoms were observed in 54.3% of the elderly individuals, average of 5.4 (s=2.5). Association between falls and the use of glasses (p<0.01) and between cognitive deficit and age (p=0.04) was observed. The identification of the profile and needs of hospitalized elderly individuals can support planning of care with a multidisciplinary focus.

Bronquiolite viral aguda: etiologia e impacto clínico imediato e tardio em pacientes atendidos em um hospital privado de São Paulo / Acute viral bronchiolitis: etiology and early and late clinical impact in patients attending a private hospital in São Paulo

Milena Siciliano Nascimento 30 March 2010 (has links)
Bronquiolite viral aguda é mundialmente a doença de vias aéreas inferiores mais comum entre lactentes e crianças jovens, sendo uma das principais causas de hospitalização na infância. Um grupo específico de crianças tem risco aumentado para desenvolver quadros mais graves sendo que os principais fatores de risco associados são: idade, sexo, co-morbidades (prematuridade, presença de displasia broncopulmonar e cardiopatia congênita, imunodeficiência), fatores ambientais e socioeconômicos e historia de atopia familiar. Os principais agentes etiológicos associados a bronquiolite são o vírus sincicial respiratório (VSR); influenza A e B; parainfluenza 1, 2 e 3 e adenovírus, picornavírus, coronavírus e metapneumovírus humano. O objetivo deste estudo foi avaliar a etiologia e o impacto clínico de infecções por vírus respiratórios em lactentes com idade entre 0 a 2 anos durante o primeiro episódio de sibilância, atendidas no Pronto Atendimento do Hospital Israelita Albert Einstein. Os vírus respiratórios foram investigados na amostra de lavado nasofaríngeo, exclusivamente por métodos de biologia molecular incluindo RT-PCR em tempo real (vírus sincicial respiratório, influenza, parainfluenza, rinovírus) RT-PCR convencional (coronavírus e metapneumovírus humano) e PCR convencional (adenovírus e bocavírus humano). Os desfechos avaliados foram impacto clínico imediato (hospitalização e admissão em unidade de terapia intensiva - UTI) e tardio (chiado recorrente), através do atendimento inicial e de entrevistas telefônicas aos 15 e 30 dias (impacto imediato) e posteriormente aos 3, 6 e 12 meses (impacto tardio). Chiado recorrente foi caracterizado pela ocorrência de três ou mais episódios de sibilância tratamento com medicação profilática para asma durante o seguimento. A verificação de associação entre as variáveis explicativas e os desfechos escolhidos foi feita através de modelo de regressão logística uni e multivariada, expressando os resultados em razão de chance (odds ratio, OR). O nível de significância adotado foi p< 0,05. Foram incluídos 77 lactentes, com mediana de idade de 6±4 meses. A identificação de pelo menos um vírus respiratório ocorreu em 72 (93%) das amostras. O vírus sincicial respiratório foi positivo em 49 amostras (64%), seguido por rinovírus (34%), enterovírus (21%), metapneumovírus humano (16%), bocavírus humano (12%), parainfluenza 3 (8%) e influenza A (2%), coronavírus (2%) e parainfluenza 1 (1%). Co-detecções foram observadas em 34 amostras (44%). Dos 77 lactentes incluídos no estudo, 32 (41%) necessitaram internação e 8 foram admitidos em UTI, sendo que estes eram mais jovens (p=0,02) e apresentaram maior tempo de internação (6,4 x 3,9 dias, p=0,012) em relação aos lactentes que internaram em apartamento. Quanto ao desfecho internação, idade mais jovem esteve associada a maior risco de internação (OR=0,83; p=0,026), enquanto atopia teve efeito protetor (OR=0,20; p=0,021). Identificação de enterovírus esteve associada a aumento do risco para internação (OR=6,03; p=0,027). Prematuridade foi a única variável associada a um significativo risco de admissão em UTI (OR=24,51; p=0,002). Após um ano de seguimento, 55% dos pacientes foram caracterizados como chiadores recorrentes, mas nenhum fator de risco ou etiologia viral estiveram associados a este desfecho. / Acute viral bronchiolitis is the most common disease of the lower respiratory tract in infants and young children throughout the world, being one of the main causes for hospitalization during infancy. A specific group of children has a greater risk for developing more servere cases, where the most important associated risk factors are: age, gender, co-morbidities (prematurity, presence of bronchopulmonary displasia and congenital heart diseases, deficiency in the immune system), environmental and social-economic factors, and a family history of allergies. The main etiological agents associated with bronchiolitis are the respiratory syncytial virus (RSV), influenza types A and B, parainfluenza types 1, 2 and 3 and adenovirus, picornavirus, coronavirus and human metapneumovirus.The objective of this study was to evaluate the etiology and clinical impact of respiratory viruses in infants aged 0 to 2 years, during the first episode of wheezing, attended at the Emergency Unit of the Albert Einstein Israeli Hospital. Respiratory viruses were investigated in nasopharyngeal aspirates, using molecular biology methods, including real time RT-PCR (respiratory syncytial virus, influenza, parainfluenza, rinovirus) conventional RT-PCR (coronavirus and human metapneumovirus) and conventional PCR (adenovirus and human bocavirus). The evaluated outcomes were immediate clinical impact (hospitalization and admission in an intensive care unit ICU) and late impacts (recurrent wheezing), in the initial approach and telephone interviews at 15 and 30 days (immediate impact) and later at 3, 6 and 12 months (late impact). Recurrent wheezing was characterized by the occurrence of three or more wheezing episodes or treatment with prophylactic medicines for asthma during the follow-up. The verification of the association between the explanatory variables and the chosen outcomes was done using uni and multivariated logistic regression models, expressing the results in odds ratio (OR). The level of significance adopted was p<0.05. Seventy-seven infants were included, with a median age of 6 ± 4 months. The identification of ate least one respiratory virus occurred in 72 (93%) of the samples. Respiratory syncytial virus tested positive in 49 samples (64%), followed by rinovirus (34%), enterovirus (21%), human metapneumovirus (16%), human bocavirus (12%), parainfluenza type 3 (8%) and influenza tipe A (2%), coronavirus (2%) and parainfluenza type 1 (1%). Co-detections were observed in 34 samples (44%). Of the 77 infants included in this study, 32 (41%) needed hospitalization and 8 were admitted to ICU, the latter ones being younger (p=0.02) and were hospitalized for a longer period of time (6.4 x 3.9 days, p=0.012) in relation to the infants who were admitted in wards. Regarding the hospitalization outcome, younger patients had a greater risk of hospitalization (OR=0.83; p=0.026), while allergies had a protective effect (OR=0.20; p=0.021). The identification of enterovirus was associated with a greater risk of hospitalization (OR=0.83; p=0.027). Prematurity was the only variable associated with a significant risk of admission in ICU (OR=24.51; p=0.002). After a follow-up one year later, 55% of the patients were characterized as recurrent wheezers, but no risk factor or viral etiology were associated with this outcome.

Content of nursing discharge notes: Associations with patient and transfer characteristics

Olsen, Rose Mari, Hellzen, Ove, Skotnes, Liv Heide, Enmarker, Ingela January 2012 (has links)
Background: In situations of care transfer of older people from hospital to home care at discharge, exchanging relevant and necessary information about the patient’s health status and individual needs are of importance to ensure continuity and appropriate nursing follow-up care. Objective: The objectives of the study were to: 1) examine the content of nurses’ discharge notes of older patients’ discharged from hospital to home care, and 2) investigate the association between the content of discharge notes and characteristics of patient and transfer. Methods: The nursing discharge notes of 70 older patients admitted to a geriatric unit and a general medicine ward at a local hospital in central Norway were analysed. The discharge notes were structured in accordance with the Well-being, Integrity, Prevention, and Safety (VIPS) model. Mean, standard deviations, and independent sample t-tests were performed to show and examine differences in use of VIPS keywords in relation to patient and transfer characteristics. To examine if use of VIPS keywords could be predicted by patient and transfer characteristics, linear multiple regression analyses were used. Results: Significant differences for mean scores on used VIPS keywords in the discharge note were found for gender, age, and medical department facility. While gender and medical department facility were significant predictors of mental related keywords in the discharge note, medical department facility was a significant predictor of physical related keywords. Conclusions: The result of this study indicate that documentation of patient status in the nursing discharge note of older patients transferred from hospital to home care is incomplete and are influenced by patient and transfer characteristics. In order to ensure continuity and appropriate nursing follow-up care, we emphasize the need for a more comprehensive approach to older patients, and that this must be reflected in the nursing discharge note.

Variation in pediatric gastroenteritis admissions among Florida counties, 1995-2002

Lee, Jean 01 June 2006 (has links)
Background: Hospitalizations for pediatric gastroenteritis are considered potentially avoidable and are used to monitor access and quality of primary care for children. Previous reports have found pediatric gastroenteritis admissions higher in Florida compared to the South and the nation.Purpose: The purpose of this project was to explore variation in county admission rates for pediatric gastroenteritis related to non-clinical factors in Florida during 1995-2002. Specific aims included identifying the unique contributions of county socioeconomic characteristics and availability of primary care resources to annual county pediatric gastroenteritis hospital admission rates. Method: The study was retrospective and longitudinal assessing variation in annual county admission rates for pediatric gastroenteritis from 1995 to 2002. Secondary data sources included Florida hospital discharge data and multiple publicly available state and federal datasets. Explanatory variables included county-level measures of socioeconomic status and primary healthcare resources. Analysis: Multivariate analysis was performed using multilevel modeling techniques. A two-level, random coefficients model was constructed in HLM6 to account for variation over years and across counties. Linear and non-linear trends over time were also assessed. Results: None of the hypotheses were supported by the data. The average pediatric gastroenteritis admission rate across all occasions and counties was 205.72 admissions per 100,000 child population. The proportion of children 0-4 years was the only significant predictor of pediatric gastroenteritis rates. Conclusion/Discussion: The significant effect of age on admission rate was not surprising and was well supported in the literature. Missing data issues and low statistical power may have contributed to the lack of significant effects of other explanatory variables

Examining Group Differences Between Suicidal Veterans Classified as Wish to Live, Ambivalent, or Wish to Die Using the Suicide Index Score

Morris, Brittany D. 01 August 2014 (has links)
A persistent difficulty in the field of psychology is identifying which individuals are at the greatest risk for suicide. Veterans of the US Military are at elevated risk for suicide as compared to the general population. One approach for designating tiers of risk is applying the “Suicide Index Score” to discriminate individuals based upon their reported wish to live (WTL) and wish to die (WTD; Kovacs & Beck, 1977). Brown, Steer, Henriques, and Beck (2005) demonstrated those who indicated a complete WTD and no WTL were at greatest risk to die. The current study expanded on previous research by using this approach with a highly elevated at-risk population of suicidal veterans. Participants for this study included 93 suicidal veterans hospitalized at the Robley Rex Veteran Affairs Medical Center in Louisville, Kentucky. The WTL and WTD items from the Scale for Suicidal Ideation-Current were used to create two quasi-independent groups: WTL/Ambivalent and WTD. The following outcome measures were included as dependent variables: Acquired Capability for Suicide Scale, Interpersonal Needs Questionnaire, Outcome Questionnaire-45.2, Suicide Attempt and Self-Injury Count, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test, and the Stages of Change Questionnaire, as well as the Suicidal Ideation, Posttraumatic Stress Disorder and Insomnia items on the Common Data Elements. T-tests were used to examine patient characteristics for continuous outcomes and chi-square analyses were used for nominal outcomes; however, no group differences were found. T-tests were then used to measure between-group differences on the dependent variables. Individuals classified in the WTD group reported significantly higher levels of thwarted belongingness t(91) = 2.89, p = .00, acquired capability t(91) = 2.64, p = .01, suicidal ideation, t(91) = 3.51, p < .001, and posttraumatic stress t(91) = 2.53, p = .01. Furthermore, a negative binomial regression was used for count outcomes and results revealed that those in the WTD group also reported significantly greater accounts of suicide attempts (incidence rate ratio [IRR] = 2.08; standard error [SE] = 0.63; 95% confidence interval [CI] 1.14-3.77; p = .02) and non-suicidal self-injury (IRR = 3.49; SE = 0.69; 95% CI 2.36-5.16; p < .001).

Heart failure in Australia: trends in determinants, incidence and survival

Najafi, Farid Unknown Date (has links)
Background and aims: Heart failure (HF) is a common health problem worldwide. Despite its importance, the epidemiology of HF is incompletely understood. Frequent references to an ‘epidemic of HF’ are at odds with recent reports of a decline in mortality from heart failure. In addition, reports based on admissions to hospital with a diagnosis of HF show that an earlier upward trend levelled off in the late 1990s in most developed countries. However, HF is a heterogeneous condition with multiple underlying causes. A decline in the severity of acute myocardial infarction (AMI), one of the major underlying causes of HF, and improvement in the treatment of patients with AMI as well as of hypertension are factors that might produce contradictory effects on the epidemiology of HF. Recent claims of a major contribution of improved survival after AMI to the reported epidemic of HF in the United States of America need to be examined in other populations. This thesis aims to define more precisely the epidemiological features of heart failure in Australia, and how these have evolved over the last decade. It examines secular trends in mortality, hospital admissions, incidence and survival related to HF. Methods: Trends in mortality from HF and admission to hospital with a diagnosis of HF are examined using computerized records of all deaths occurring in Australia for calendar years 1997-2003 and National Hospital Morbidity Data for financial years 1996-1997 to 2003-2004, obtained from the Australian Institute of Health and Welfare. A death or admission to hospital was defined as involving HF if at least one of the causes of death or one of the diagnoses of each separation was coded to any of the relevant rubrics within the International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) or 10th Revision, Australian Modification (ICD-10-AM). The analyses are based on age- and sex-specific death and hospital separation rates for HF either as underlying cause (or principal diagnosis) or mentioned anywhere on the death certificate (or recorded in any diagnostic position in the hospital electronic file) for each calendar or financial year. The investigation of trends in incidence and outcome of early-onset HF (HF complicating an index AMI within 28 days) and late-onset HF after AMI (HF developing 28 days after an index AMI) was based on the World Health Organization MONItoring trends and determinants of CArdiovascular disease (MONICA) register in Western Australia. The study included all residents aged 25-64 years of Perth, the capital city of Western Australia, who were admitted to hospital between 1988 and 1993 with non-fatal definite AMI and who had no history of AMI or HF in the hospital record. Trends in incidence and outcome of early- and late-onset HF were investigated using appropriate statistical methods. Results: From a total of 907,242 deaths occurring in Australia between 1997 and 2003, heart failure was coded as the underlying cause of death (UCD) for 29,341 (3.2%) and was mentioned anywhere on the death certificate in 135,268 (14.9%). Over this period, in both sexes, there were decreases in the absolute numbers of deaths and in the age-specific and age-standardized mortality rates for HF either as UCD or mentioned anywhere on the death certificate. HF was mentioned in 24.6% and 17.8% of deaths attributed to ischaemic heart disease and circulatory disease respectively, and these proportions remained unchanged over the period of study. In addition, HF as UCD accounted for 8.3% of deaths due to circulatory disease and this did not change from 1997 to 2003. From a total of 48,562,285 separations from hospital between 1996-7 and 2003-4, HF was coded as the principal diagnosis for 344,081 (0.8%) and was mentioned anywhere on the hospital record in 1,212,109 (2.5%). While the number of separations with HF remained stable, the age- and sex-standardized separation rate for HF recorded as principal diagnosis decreased from 2.0 per 1000 population in 1996-1997 to 1.7 per 1000 population in 2003- 2004. The corresponding values for HF recorded in any diagnostic position were 7.8 and 5.0 per 1000 population. From all patients (N = 4006) who met the criteria for first-ever, non fatal ‘definite’ AMI in the Perth MONICA Register, 897 (22.4%) had early-onset HF complicating the index event. After adjustment for age and sex, the odds of developing HF declined by 13% (odds ratio for the period 1989-1993 relative to 1984-1988 = 0.87, 95% confidence interval (95%CI): 0.75 to 1.01). After adjustment for age and history of diabetes and hypertension, the hazard of death in patients with early-onset HF (i.e. case fatality) declined by 26% (HR for the period 1989-1993 relative to 1984-1988 = 0.74, 95%CI: 0.57 to 0.96). Of 3109 patients who did not develop early-onset HF, 406 (13.1%) had at least one subsequent hospital admission with a diagnosis of HF (defined as late-onset HF). Following adjustment for age and sex, the hazard ratio for late-onset HF for the period 1989-1993 relative to 1984-1988 was 0.85 (95% confidence interval (95%CI): 0.69-1.04). History of diabetes and hypertension, current smoking, length of initial admission for AMI, recurrent acute coronary syndrome and coronary artery revascularization procedures were predictors of late-onset HF. After a median follow-up of 3.2 years and adjustment for age (≥70 years) and history of diabetes, the hazard of death in patients with late-onset HF did not change over the period of study (HR for year = 1.02, 95%CI: 0.98 to 1.06). Conclusion: For reasons discussed in the body of the thesis, the observed decline in mortality from HF measured as either number of deaths or rate probably reflects a real change in the epidemiology of HF. In addition, there was no increase in the number of hospital admissions involving HF and standardized rates of hospital separations fell in Australia between 1996 and 2004. These results do not support a major increase in the caseload of HF over recent years. In addition, a decline in the risk of early- and late-onset HF after AMI as well as all the evidence on decline in incidence and severity of coronary artery disease and hypertension argue against an increase in inflow from these two important risk factors of HF. However, taking all of the influences on the epidemiology of HF together, it is likely that because of the increasing number of older people, the number of new cases of HF will rise over the next few years, even if the incidence rate falls.
