Using ICD-10-AM codes to characterise hospital-acquired complications

This paper describes the limitations of using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) to characterise patient harm in hospitals. Limitations were identified during a project to use diagnoses flagged by Victorian coders as hospital-acquired to devise a classification of 144 categories of hospital acquired diagnoses (the Classification of Hospital Acquired Diagnoses or CHADx). CHADx is a comprehensive data monitoring system designed to allow hospitals to monitor their complication rates month-to-month using a standard method. Difficulties in identifying a single event from linear sequences of codes due to the absence of code linkage were the major obstacles to developing the classification. Obstetric and perinatal episodes also presented challenges in distinguishing condition onset, that is, whether conditions were present on admission or arose after formal admission to hospital. Used in the appropriate way, the CHADx allows hospitals to identify areas for future patient safety and quality initiatives. The value of timing information and code linkage should be recognised in the planning stages of any future electronic systems.

Drink driver rehabilitation and new developments

Drink driving continues to be a major public health concern. Significant reductions in road fatalities have been achieved due largely to the Safe Systems Approach to road safety. However, serious injury due to road trauma has increased in most Australian jurisdictions. Some subgroups of drink drivers such as young drivers and Indigenous drink drivers are vulnerable to road trauma and have been less responsive to countermeasures based on the deterrence philosophy. Drink driving rehabilitation programs that use a combination of deterrence, education and social control models have been moderately successful in reducing recidivism. However, most of these programs do not adequately address alcohol related health concerns or the needs of drink drivers in remote and rural areas. Scant attention has also been given to the use of brief online drink driving interventions. The ‘Under the Limit’ (UTL) drink driving rehabilitation program has recently been revised to ensure that its content is contemporary, relevant and evidenced based. CARRS-Q has also developed a brief online program that targets first time convicted drink drivers who have a BAC under 0.15g/100mL and a culturally sensitive program that targets Aboriginals and Torres Strait Islanders living in rural and remote areas. These new developments will be discussed in the context of the most effective road safety educational policy and practice.

Carotenoid and vitamin content of Karat and other Micronesian banana cultivars.

We previously found high carotenoid levels in Karat and other Micronesian bananas, indicating potential importance for alleviating vitamin A deficiency and other nutritionally related health problems in the Federated States of Micronesia. Past work focused on carotenoid and mineral analyses, whereas here we investigated 16 cultivars (most not previously analysed) for a broader micronutrient profile, including seven vitamins. Karat carotenoid levels were higher than in previous analyses, confirming Karat as exceptionally carotenoid-rich. We identified an additional 10 carotenoid-rich cultivars, expanding the range having potential for alleviating vitamin A deficiency. A striking finding is the high riboflavin level in Karat, including high levels of uncharacterized flavonoids. Niacin and α-tocopherol are at levels that may contribute importantly to dietary intake within normal patterns of consumption. These data present a more complete basis for promoting the nutritional benefits of these banana cultivars where they are consumed in the Pacific, and potential benefits for promoting elsewhere.

Productivity, carbon assimilation and intra-annual change in tropical reef platform seagrass communities of the Torres Strait, north-eastern Australia

Detailed data on seagrass distribution, abundance, growth rates and community structure information were collected at Orman Reefs in March 2004 to estimate the above-ground productivity and carbon assimilated by seagrass meadows. Seagrass meadows were re-examined in November 2004 for comparison at the seasonal extremes of seagrass abundance. Ten seagrass species were identified in the meadows on Orman Reefs. Extensive seagrass coverage was found in March (18,700 ha) and November (21,600 ha), with seagrass covering the majority of the intertidal reef-top areas and a large proportion of the subtidal areas examined. There were marked differences in seagrass above-ground biomass, distribution and species composition between the two surveys. Major changes between March and November included a substantial decline in biomass for intertidal meadows and an expansion in area of subtidal meadows. Changes were most likely a result of greater tidal exposure of intertidal meadows prior to November leading to desiccation and temperature-related stress. The Orman Reef seagrass meadows had a total above-ground productivity of 259.8 t DW day-1 and estimated carbon assimilation of 89.4 t C day-1 in March. The majority of this production came from the intertidal meadows which accounted for 81% of the total production. Intra-annual changes in seagrass species composition, shoot density and size of meadows measured in this study were likely to have a strong influence on the total above-ground production during the year. The net estimated above-ground productivity of Orman Reefs meadows in March 2004 (1.19 g C m-2 day-1) was high compared with other tropical seagrass areas that have been studied and also higher than many other marine, estuarine and terrestrial plant communities.

Childhood and adolescent antecedents of work stress and early atherosclerosis

Work stress is after musculoskeletal disorders the second most common work-related health problem in the European Union, affecting 28% of EU employees. Furthermore, a 50% excessive cardiovascular disease risk among employees with work stress is reported. High job demands combined with low job control according to the Job Demands-Job Control model, or high effort combined with low rewards according to Effort-Reward Imbalance model, are likely to produce work stress in the majority of employees. Atherosclerotic wall thickening is a validated marker of an increased risk of cardiovascular disease. This study examined the role of childhood and adolescent factors as antecedents of work stress and early atherosclerosis, and in the relationship between them. The Cardiovascular Risk in Young Finns Study, (the CRYF project) started in 1980 when the participants were at the age of three to 18 years. Follow-ups have been conducted every three years until 1992, after that in 1997 and 2001, and the latest is ongoing in 2008. The participants parents reported their socioeconomic position in 1980 and 1983, and their life satisfaction in 1983. Biological risk factors were measured in 1980 and 2001. Type A behaviour was reported in 1986, 1989 and 2001. In the 2001 follow-up when the participants were aged 24 to 39, work stress was assessed from responses to questionnaires on job demands-job control and effort-reward imbalance, and education. Ultrasound measurement of the carotid intima-media thickness (CIMT) was used to assess atherosclerosis. There were 755, 746, 1014 and 494 participants in studies I-IV, respectively. The results showed that low parental socioeconomic position and parental life dissatisfaction during childhood and adolescence predicted higher levels of job strain 18 years later, and that education mediated the relationship between parental socioeconomic position and job strain. Childhood and adolescent family factors were not related to the effort-reward imbalance. Parental life satisfaction was associated with high rewards at work among the men, and high parental socioeconomic position was associated with high reward among the women. Among the men, the eagerness-energy component of Type A behaviour across different developmental periods predicted increased CIMT. Among the women, hard-driving component of Type A behaviour predicted decreased CIMT. Low leadership characteristic in adolescence and early adulthood was associated with both high job strain and increased CIMT, and attenuated the relationship between job strain and CIMT to non-significance in men. The current findings add to the literature on the relationship between job strain and health literature in adopting a developmental perspective. The results imply that work stress does not completely originate from work. There are childhood and adolescent environmental and dispositional effects on work stress and CIMT several years later, and these partly seem to operate through educational attainment.

Air pollution and fasting blood glucose: A longitudinal study in China

Limited studies have examined the associations between air pollutants [particles with diameters of 10um or less (PM10), sulfur dioxide (SO2), and nitrogen dioxide (NO2)] and fasting blood glucose (FBG). We collected data for 27,685 participants who were followed during 2006 and 2008. Generalized Estimating Equation models were used to examine the effects of air pollutants on FBG while controlling for potential confounders. We found that increased exposure to NO2, SO2 and PM10 was significantly associated with increased FBG levels in single pollutant models (p<0.001). For exposure to 4 days’ average of concentrations, a 100 µg/m3 increase in SO2, NO2, and PM10 was associated with 0.17 mmol/L (95%CI: 0.15–0.19), 0.53 mmol/L (95%CI: 0.42–0.65), and 0.11 mmol/L (95%CI: 0.07–0.15) increase in FBG, respectively. In the multi-pollutant models, the effects of SO2 were enhanced, while the effects of NO2 and PM10 were alleviated. The effects of air pollutants on FBG were stronger in female, elderly, and overweight people than in male, young and underweight people. In conclusion, the findings suggest that air pollution increases the levels of FBG. Vulnerable people should pay more attention on highly polluted days to prevent air pollution-related health issues.

Classifying genotype by environment interactions for targeted germplasm deployment with a focus on Eucalyptus

A novel methodology for describing genotype by environment interactions estimated from multi-environment field trials is described and an empirical example using an extensive trial network of eucalypts is presented. The network of experiments containing 65 eucalypts was established in 38 replicated field trials across the tropics and subtropics of eastern Australia, with a selection of well-tested species used to provide a more detailed examination of productivity differentials across environmental gradients. By focusing on changes in species’ productivity across environmental gradients, the results are applicable for all species established across the range of environments evaluated in the trial network and simultaneously classify species and environments so that results may be applied across the landscape. The methodology developed was able to explain most (93 %) of the variation in the selected species relative changes in productivity across the various environmental variables examined. Responses were primarily regulated by changes in variables related to water availability and secondarily by temperature related variables. Clustering and ordination can identify groups of species with similar physiological responses to environment and may also guide the parameterisation and calibration of process based models of plant growth. Ordination was particularly useful in the identification of species with distinct environmental response patterns that would be useful as probes for extracting more information from future trials.

Age and growth of two newly established invasive populations of Tilapiamariae in northern Australia

Sagittal otoliths were used to age the samples of Tilapia mariae collected from a coastal river and an impoundment. Validation of sagittae checks was achieved using both quantitative marginal increment analysis and by tetracycline marking of the otoliths of fish kept in tanks and in a farm dam. The annulus pattern on the otoliths was generally clear and their formation appeared to be temperature related and largely completed in the Austral spring around September and October. Male T. mariae grow faster and larger than females and the maximum ages of fish from the coastal river and impoundment was 9+ and 4+ years, respectively. Past fish surveys and the absence of older age classes in the impoundment population would suggest that this population was only very recently established.

Patterns of service utilisation within Australian hepatology clinics: High prevalence of advanced liver disease

Accepted Article Abstract Background: Liver diseases in Australia are estimated to affect 6 million people with a societal cost of $51 billion annually. Information about utilization of specialist hepatology care is critical in informing policy makers about the requirements for delivery of hepatology-related health care. Aims: This study examined etiology and severity of liver disease seen in a tertiary hospital hepatology clinic, as well as resource utilisation patterns. Methods: A longitudinal cohort study included consecutive patients booked in hepatology outpatient clinics during a 3 month period. Subsequent outpatient appointments for these patients over the following 12 months were then recorded. Results: During the initial 3 month period 1471 appointments were scheduled with a hepatologist, 1136 of which were attended. 21% of patients were “new cases”. Hepatitis B (HBV) was the most common disease etiology for new cases (37%). Advanced disease at presentation varied between etiology, with HBV (5%), Hepatitis C (HCV) (31%), non-alcoholic fatty liver disease (NAFLD) (46%) and alcoholic liver disease (ALD) (72%). Most patients (83%) attended multiple hepatology appointments, and a range of referrals patterns for procedures, investigations and other specialty assessments were observed. Conclusions: There is a high prevalence of HBV in new case referrals. Patients with HCV, NAFLD and ALD have a high prevalence of advanced liver disease at referral, requiring ongoing surveillance for development of decompensated liver disease and liver cancer. These findings that describe patterns of health service utilisation among patients with liver disease provide useful information for planning sustainable health service provision for this clinical population

Developing standardized methods to assess cost of healthy and unhealthy (current) diets in Australia

Unhealthy diets contribute at least 14% to Australia's disease burden and are driven by ‘obesogenic’ food environments. Compliance with dietary recommendations is particularly poor amongst disadvantaged populations including low socioeconomic groups, those living in rural/remote areas and Aboriginal and Torres Strait Islanders. The perception that healthy foods are expensive is a key barrier to healthy choices and a major determinant of diet-related health inequities. Available state/regional/local data (limited and non-comparable) suggests that, despite basic healthy foods not incurring GST, the cost of healthy food is higher and has increased more rapidly than unhealthy food over the last 15 years in Australia. However, there were no nationally standardised tools or protocols to benchmark, compare or monitor food prices and affordability in Australia. Globally, we are leading work to develop and test approaches to assess the price differential of healthy and less-healthy (current) diets under the food price module of the International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS). This presentation describes contextualization of the INFORMAS approach to develop standardised Australian tools, survey protocols and data collection and analysis systems. The ‘healthy diet basket’ was based on the Australian Foundation Diet, 1 The ‘current diet basket’ and specific items included in each basket, were based on recent national dietary survey data.2 Data collection methods were piloted. The final tools and protocols were then applied to measure the price and affordability of healthy and less healthy (current) diets of different household groups in diverse communities across the nation. We have compared results for different geographical locations/population subgroups in Australia and assessed these against international INFORMAS benchmarks. The results inform the development of policy and practice, including those relevant to mooted changes to the GST base, to promote nutrition and healthy weight and prevent chronic disease in Australia.

Medicalising Prohibition : Harm reduction in Finnish and International Drug Policy

The increase in drug use and related harms in the late 1990s in Finland has come to be referred to as the second drug wave. In addition to using criminal justice as a basis of drug policy, new kinds of drug regulation were introduced. Some of the new regulation strategies were referred to as "harm reduction". The most widely known practices of harm reduction include needle and syringe exchange programmes for intravenous drug users and medicinal substitution and maintenance treatment programmes for opiate users. The purpose of the study is to examine the change of drug policy in Finland and particularly the political struggle surrounding harm reduction in the context of this change. The aim is, first, to analyse the content of harm reduction policy and the dynamics of its emergence and, second, to assess to what extent harm reduction undermines or threatens traditional drug policy. The concept of harm reduction is typically associated with a drug policy strategy that employs the public health approach and where the principal focus of regulation is on drug-related health harms and risks. On the other hand, harm reduction policy has also been given other interpretations, relating, in particular, to human rights and social equality. In Finland, harm reduction can also be seen to have its roots in criminal policy. The general conclusion of the study is that rather than posing a threat to a prohibitionist drug policy, harm reduction has come to form part of it. The implementation of harm reduction by setting up health counselling centres for drug users with the main focus on needle exchange and by extending substitution treatment has implied the creation of specialised services based on medical expertise and an increasing involvement of the medical profession in addressing drug problems. At the same time the criminal justice control of drug use has been intensified. Accordingly, harm reduction has not entailed a shift to a more liberal drug policy nor has it undermined the traditional policy with its emphasis on total drug prohibition. Instead, harm reduction in combination with a prohibitionist penal policy constitutes a new dual-track drug policy paradigm. The study draws on the constructionist tradition of research on social problems and movements, where the analysis centres on claims made about social problems, claim-makers, ways of making claims and related social mobilisation. The research material mainly consists of administrative documents and interviews with key stakeholders. The doctoral study consists of five original articles and a summary article. The first article gives an overview of the strained process of change of drug policy and policy trends around the turn of the millennium. The second article focuses on the concept of harm reduction and the international organisations and groupings involved in defining it. The third article describes the process that in 1996 97 led to the creation of the first Finnish national drug policy strategy by reconciling mutually contradictory views of addressing the drug problem, at the same as the way was paved for harm reduction measures. The fourth article seeks to explain the relatively rapid diffusion of needle exchange programmes after 1996. The fifth article assesses substitution treatment as a harm reduction measure from the viewpoint of the associations of opioid users and their family members.

Physical Properties of Deep Drill Cores : Implications for Meteorite Impact Effects and Crustal Structures

Physical properties provide valuable information about the nature and behavior of rocks and minerals. The changes in rock physical properties generate petrophysical contrasts between various lithologies, for example, between shocked and unshocked rocks in meteorite impact structures or between various lithologies in the crust. These contrasts may cause distinct geophysical anomalies, which are often diagnostic to their primary cause (impact, tectonism, etc). This information is vital to understand the fundamental Earth processes, such as impact cratering and associated crustal deformations. However, most of the present day knowledge of changes in rock physical properties is limited due to a lack of petrophysical data of subsurface samples, especially for meteorite impact structures, since they are often buried under post-impact lithologies or eroded. In order to explore the uppermost crust, deep drillings are required. This dissertation is based on the deep drill core data from three impact structures: (i) the Bosumtwi impact structure (diameter 10.5 km, 1.07 Ma age; Ghana), (ii) the Chesapeake Bay impact structure (85 km, 35 Ma; Virginia, U.S.A.), and (iii) the Chicxulub impact structure (180 km, 65 Ma; Mexico). These drill cores have yielded all basic lithologies associated with impact craters such as post-impact lithologies, impact rocks including suevites and breccias, as well as fractured and unfractured target rocks. The fourth study case of this dissertation deals with the data of the Paleoproterozoic Outokumpu area (Finland), as a non-impact crustal case, where a deep drilling through an economically important ophiolite complex was carried out. The focus in all four cases was to combine results of basic petrophysical studies of relevant rocks of these crustal structures in order to identify and characterize various lithologies by their physical properties and, in this way, to provide new input data for geophysical modellings. Furthermore, the rock magnetic and paleomagnetic properties of three impact structures, combined with basic petrophysics, were used to acquire insight into the impact generated changes in rocks and their magnetic minerals, in order to better understand the influence of impact. The obtained petrophysical data outline the various lithologies and divide rocks into four domains. Based on target lithology the physical properties of the unshocked target rocks are controlled by mineral composition or fabric, particularly porosity in sedimentary rocks, while sediments result from diverse sedimentation and diagenesis processes. The impact rocks, such as breccias and suevites, strongly reflect the impact formation mechanism and are distinguishable from the other lithologies by their density, porosity and magnetic properties. The numerous shock features resulting from melting, brecciation and fracturing of the target rocks, can be seen in the changes of physical properties. These features include an increase in porosity and subsequent decrease in density in impact derived units, either an increase or a decrease in magnetic properties (depending on a specific case), as well as large heterogeneity in physical properties. In few cases a slight gradual downward decrease in porosity, as a shock-induced fracturing, was observed. Coupled with rock magnetic studies, the impact generated changes in magnetic fraction the shock-induced magnetic grain size reduction, hydrothermal- or melting-related magnetic mineral alteration, shock demagnetization and shock- or temperature-related remagnetization can be seen. The Outokumpu drill core shows varying velocities throughout the drill core depending on the microcracking and sample conditions. This is similar to observations by Kern et al., (2009), who also reported the velocity dependence on anisotropy. The physical properties are also used to explain the distinct crustal reflectors as observed in seismic reflection studies in the Outokumpu area. According to the seismic velocity data, the interfaces between the diopside-tremolite skarn layer and either serpentinite, mica schist or black schist are causing the strong seismic reflectivities.

Physical properties of a boreal clay soil under differently managed perennial vegetation

The physical properties of surface soil horizons, essentially pore size, shape, continuity and affinity for water, regulate water entry into the soil. These properties are prone to changes caused by natural forces and human activity. The hydraulic properties of the surface soil greatly impact the generation of surface runoff and accompanied erosion, the major concern of agricultural water protection. The general target of this thesis was to improve our understanding of the structural and hydraulic properties of boreal clay soils. Physical properties of a clayey surface soil (0 - 10 cm, clay content 51%), with a micaceous/illitic mineralogy subjected to three different management practices of perennial vegetation, were studied. The study sites were vegetated buffer zones located side by side in SW Finland: 1) natural vegetation with no management, 2) harvested once a year, and 3) grazed by cattle. The soil structure, hydraulic properties, shrinkage properties and soil water repellency were determined at all sites. Two distinct flow domains were evident. The surface soil was characterized by subangular blocky, angular blocky and platy aggregates. Hence, large, partially accommodated, irregular elongated pores dominated the macropore domain at all sites. The intra-aggregate pore system was mostly comprised of pores smaller than 30 μm, which are responsible for water storage. Macropores at the grazed site, compacted by hoof pressure, were horizontally oriented and pore connectivity was poorest, which decreased water and air flux compared with other sites. Drying of the soil greatly altered its structure. The decrease in soil volume between wet and dry soil was 7 - 10%, most of which occurred in the moisture range of field conditions. Structural changes, including irreversible collapse of interaggregate pores, began at matric potentials around -6 kPa indicating, instability of soil structure against increasing hydraulic stress. Water saturation and several freezethaw cycles between autumn and spring likely weakened the soil structure. Soil water repellency was observed at all sites at the time of sampling and when soil was dryer than about 40 vol.%. (matric potential < -6 kPa). Therefore, water repellency contributes to water flow over a wide moisture range. Water repellency was also observed in soils with low organic carbon content (< 2%), which suggests that this phenomenon is common in agricultural soils of Finland due to their relatively high organic carbon content. Aggregate-related pedofeatures of dense infillings described as clay intrusions were found at all sites. The formation of these intrusions was attributed to clay dispersion and/or translocation during spring thaw and drying of the suspension in situ. These processes generate very new aggregates whose physical properties are most probably different from those of the bulk soil aggregates. Formation of the clay infillings suggested that prolonged wetness in autumn and spring impairs soil structure due to clay dispersion, while on the other hand it contributes to the pedogenesis of the soil. The results emphasize the dynamic nature of the physical properties of clay soils, essentially driven by their moisture state. In a dry soil, fast preferential flow is favoured by abundant macropores including shrinkage cracks and is further enhanced by water repellency. Increase in soil moisture reduces water repellency, and swelling of accommodated pores lowers the saturated hydraulic conductivity. Moisture- and temperature-related processes significantly alter soil structure over a time span of 1 yr. Thus, the pore characteristics as well as the hydraulic properties of soil are time-dependent.

As transformações no ensino na saúde: um estudo sobre a extensão universitária e sua relação com a formação do profissional de saúde para o SUS

HENRIQUES, Regina Lúcia Monteiro.2011. 182 f. Tese (Doutorado em Saúde Coletiva) Instituto de Medicina Social, Universidade do Estado do Rio de Janeiro, Rio de Janeiro, 2011. Este estudo trata dos processos de mudança na formação em saúde, especialmente das questões político estruturais da articulação do ensino e da extensão para a construção de estratégias de transformação dos cursos da área da saúde. Tem por objetivos analisar as perspectiva dos sujeitos envolvidos na transformação curricular no que diz respeito à articulação entre práticas de ensino, extensão universitária e saúde, a constituição de novos cenários de prática e sua relação com a extensão universitária, assim como examinar os sentidos atribuídos pelos sujeitos aos processos políticos internos e externos às instituições de ensino. Parte-se da compreensão de que há em andamento um grande movimento de lutas pela mudança na formação em saúde e de algumas das ideias que têm sido discutidas e difundidas na defesa da reorientação da formação em saúde baseada em princípios e diretrizes consoantes com a política de saúde e com a defesa de direitos de cidadania. Baseia-se em concepções de espaço cotidiano das instituições de formação superior em saúde e dos serviços de saúde e outros cenários de prática. Reflete sobre a responsabilidade política das instituições formadoras e da extensão universitária como lugar de tornar públicas as posições e valores defendidos para as práticas do cuidado e da relação social e política da universidade. Para a operacionalização do estudo, foram escolhidas duas instituições universitárias que se apresentaram e que foram selecionadas no programa do Pro-Saúde. Foram realizadas entrevistas com roteiro semi-estruturado com protagonistas de processos de mudança na formação nestas instituições, em três profissões da área da saúde, enfermagem, medicina e odontologia. Fez-se analise hermenêutica a partir dos sentidos que foram atribuídos a estas experiências concretas pelos atores que as empreenderam. Definiu-se três categorias de análise, a dimensão das políticas governamentais de incentivo a mudanças na formação em saúde e os efeitos das mesmas para as instituições de ensino; a ampliação de cenários de prática, as estratégias de aproximação entre os mundos do ensino e do trabalho e se significaram novas práticas de cuidado; relação existente entre os processos de transformação curricular e a extensão universitária. A extensão vem adquirindo protagonismo na construção de dispositivos de enfrentamento e superação das dificuldades e resistências nos processos de transformação curricular, além de criar com relativa liberdade novas possibilidades espaciais e conceituais para o cuidado em saúde, porém pelos próprios sentidos que assume desde a invisibilidade até a redenção da universidade sua baixa institucionalidade e reflexão impede que sua potencialidade seja tomada como aliada nestes processos de modo mais sistemático e impactante.

Impacto econômico do absenteísmo de enfermagem por doença em um hospital universitário do Rio de Janeiro-RJ

Trata-se de uma pesquisa documental, retrospectiva de fonte secundária,que adota uma abordagem quantitativa descritiva-exploratória. A partir da constatação de altos índices de absenteísmo nas unidades hospitalares, despertou-se o interesse em estudar os custos diretos das doenças ocupacionais que levam aos afastamentos e seu impacto econômico para o orçamento de recursos humanos de um hospital universitário do Rio de Janeiro. Neste contexto, definiu-se como objeto de estudo, o impacto econômico do absenteísmo por doença na equipe de enfermagem e, como objetivos: identificar as causas prevalentes de afastamentos no hospital universitário, de acordo com Classificação Internacional de Doenças e Problemas Relacionados a Saúde (CID-10); estimar os custos diretos mínimos das doenças que afastaram o trabalhador de enfermagem; estimar o custo real aproximado do absenteísmo relacionado a 1 (um) dia de trabalho prestado pelos trabalhadores de enfermagem, com projeção de 1 (um) mês e 1(um) ano numa visão operacional do Sistema Único de Saúde (SUS). Foi utilizada uma amostra estratificada de prontuários dos profissionais de saúde da equipe de enfermagem (enfermeiros e técnicos de enfermagem), a partir do seguinte critério de inclusão: profissionais de enfermagem concursados com afastamento no ano de 2010 e com diagnóstico médico determinante do afastamento, definido claramente. Para a coleta das informações foi feita a apreciação dos documentos arquivados no Serviço de Saúde do Trabalhador do hospital estudado e contou com a apreciação de especialistas médicos relativos aos grupos de diagnósticos estudados, orientados por roteiros criados pela pesquisadora. Os dados foram analisados e armazenados no programa Statistical Package for the Social Sciences (SPSS) versão 15 e no editor Microsoft excel 2003. Dentre os resultados obtidos tiveram destaque para as seguintes causas de afastamento, respectivamente, às doenças do sistema osteomuscular, os fatores que influenciam o estado de saúde e o contato com serviços de saúde, os transtornos mentais e comportamentais, as lesões, envenenamento e outras consequencias de causas externas e, as doenças do sistema circulatório, que representam um custo estimado aproximado de R$ 2,6 milhões. Pôde-se constatar que o impacto econômico do absenteísmo decorrentes dos agravos à saúde para o orçamento de recursos humanos do hospital universitário foi de aproximadamente 2,7%. O custo real aproximado do absenteísmo de enfermagem por dia, foi avaliado em R$ 92,50, tendo projeção mensal de R$ 2.775,00 e anual de R$ 33.300,00. Recomenda-se avaliar o absenteísmo dos profissionais regularmente para identificar as causas reais do absenteísmo por doença, a fim de definir metas para os programas de intervenção à saúde dos trabalhadores e promover uma Gestão participativa que favoreça uma análise do processo de trabalho no que concerne o atendimento das necessidades de saúde e operacionais da força de trabalho, determinantes do absenteísmo.
