Towards a Hybrid Method to Categorize Interruptions and Activities in Healthcare

Objective Interruptions are known to have a negative impact on activity performance. Understanding how an interruption contributes to human error is limited because there is not a standard method for analyzing and classifying interruptions. Qualitative data are typically analyzed by either a deductive or an inductive method. Both methods have limitations. In this paper a hybrid method was developed that integrates deductive and inductive methods for the categorization of activities and interruptions recorded during an ethnographic study of physicians and registered nurses in a Level One Trauma Center. Understanding the effects of interruptions is important for designing and evaluating informatics tools in particular and for improving healthcare quality and patient safety in general. Method The hybrid method was developed using a deductive a priori classification framework with the provision of adding new categories discovered inductively in the data. The inductive process utilized line-by-line coding and constant comparison as stated in Grounded Theory. Results The categories of activities and interruptions were organized into a three-tiered hierarchy of activity. Validity and reliability of the categories were tested by categorizing a medical error case external to the study. No new categories of interruptions were identified during analysis of the medical error case. Conclusions Findings from this study provide evidence that the hybrid model of categorization is more complete than either a deductive or an inductive method alone. The hybrid method developed in this study provides the methodical support for understanding, analyzing, and managing interruptions and workflow.

Utilização do brinquedo terapêutico na assistência à criança hospitalizada

Estudo exploratório e descritivo, parte integrante de um projeto de parceria entre o Serviço de Enfermagem e de Terapia Ocupacional no preparo da criança para as cirurgias eletivas no Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo. OBJETIVO: utilizar o brinquedo como recurso terapêutico no alívio das tensões reais e inconscientes da criança em relação à hospitalização. MÉTODO: Foi construído um instrumento de coleta dos dados em forma de roteiro observacional, e aplicado em dois momentos: o primeiro consiste no dia anterior à realização da cirurgia e o segundo momento no dia da cirurgia imediatamente antes de sua realização. Utilizamos a contação de história e a demonstração das intervenções de enfermagem nos brinquedos (bonecos) com equipamentos e materiais comumente utilizados na hospitalização (luvas, aventais cirúrgico, máscara facial e gorro cirúrgico). RESULTADOS: Dentre as 21 variáveis de comportamento observadas, oito obtiveram diferença estatisticamente significativa com teste de McNemar (p>0,05). CONCLUSÃO: brincar interativamente proporciona à criança hospitalizada interagir com o ambiente hospitalar, expressar os seus sentimentos e emoções e provê recursos para a assistência humanizada.

Comportamentos lúdicos entre crianças do nordeste do Brasil: categorização de brincadeiras

Este artigo visa categorizar as brincadeiras das crianças de um povoado rural do nordeste do Brasil. Foram observadas individualmente 32 crianças entre dois e 12 anos, de ambos os sexos, brincando em ambiente livre, em sessões de cinco minutos. A categoria de 'brincadeiras simbólicas' foi a mais observada (49%). Os temas das brincadeiras simbólicas estavam predominantemente atrelados ao modo de vida local. Diferenças de gênero foram observadas e analisadas. Os dados sugerem que meninas brincam mais simbolicamente, enquanto as brincadeiras dos meninos são mais variadas. A relação entre brincadeira e contexto baseia-se no aproveitamento das potencialidades que o ambiente oferece para o desenvolvimento da criança caracterizando as relações entre aspectos particulares de cada ambiente e as atividades lúdicas desenvolvidas.

Intrinsic Dissolution as a Tool for Evaluating Drug Solubility in Accordance with the Biopharmaceutics Classification System

The Biopharmaceutics Classification System (BCS) is a tool that was created to categorize drugs into different groups according to their solubility and permeability characteristics. Through a combination of these factors and physiological parameters, it is possible to understand the absorption behavior of a drug in the gastrointestinal tract, thus contributing to cost and time reductions in drug development, as well as reducing exposure of human subjects during in vivo trials. Solubility is attained by determining the equilibrium under conditions of physiological pH, while different methods may be employed for evaluating permeability. On the other hand, the intrinsic dissolution rate (IDR), which is defined as the rate of dissolution of a pure substance under constant temperature, pH, and surface area conditions, among others, may present greater correlation to the in vivo dissolution dynamic than the solubility test. The purpose of this work is to discuss the intrinsic dissolution test as a tool for determining the solubility of drugs within the scope of the Biopharmaceutics Classification System (BCS).

Effect of tissue Doppler on the accuracy of novice and expert interpreters of Dobutamine echocardiography

The subjective interpretation of dobutamine echocardiography (DBE) makes the accuracy of this technique dependent on the experience of the observer, and also poses problems of concordance between observers. Myocardial tissue Doppler velocity (MDV) may offer a quantitative technique for identification of coronary artery disease, but it is unclear whether this parameter could improve the results of less expert readers and in segments with low interobserver concordance. The aim of this study was to find whether MDV improved the accuracy of wall motion scoring in novice readers, experienced echocardiographers, and experts in stress echocardiography, and to identify the optimal means of integrating these tissue Doppler data in 77 patients who underwent DBE and angiography. New or worsening abnormalities were identified as ischemia and abnormalities seen at rest as scarring. Segmental MDV was measured independently and previously derived cutoffs were applied to categorize segments as normal or ab normal. Five strategies were used to combine MDV and wall motion score, and the results of each reader using each strategy were compared with quantitative coronary angiography. The accuracy of wall motion scoring by novice (68 +/- 3%) and experienced echocardiographers (71 +/- 3%) was less than experts in stress echocardiography (88 +/- 3%, p < 0.001). Various strategies for integration with MDV significantly improved the accuracy of wall motion scoring by novices from 75 +/- 2% to 77 +/- 5% (p < 0.01). Among the experienced group, accuracy improved from 74 +/- 2% to 77 +/- 5% (p < 0.05), but in the experts, no improvement was seen from their baseline accuracy. Integration with MDV also improved discordance related to the basal segments. Thus, use of MDV in all segments or MDV in all segments with wall motion scoring in the apex offers an improvement in sensitivity and accuracy with minimal compromise in specificity.

The effects of status on subgroup relations

Two experiments were conducted to assess the impact of status differentials on subgroup attitudes and behaviours. In Experiment 1, 73 maths-science students were led to believe they had higher or lower status than humanities students. They then performed a non-interactive decision-making task during which they were categorized exclusively as a university student (superordinate condition), or as a university student and maths-science student simultaneously (subgroups condition). Experiment 2 (N = 98) differed from Experiment I in that perceptions of relative subgroup status were measured rather than manipulated. Consistent with social identity theory, subgroup members tended to categorize themselves more at the superordinate (university) level the lower status they considered their subgroup to be. In Experiment 2, a series of interactions also emerged, showing that status and inter-subgroup bias were positively related when the participants had been categorized exclusively at the superordinate level. When superordinate and subgroup identities were activated simultaneously, perceptions of status had no effect on levels of bias. The results were interpreted in terms of participants' needs for identity enhancement and identity distinctiveness.

Effects of physical activity on emotional well-being among older Australian women - Cross-sectional and longitudinal analyses

Objective: To explore relationships between physical activity and mental health cross-sectionally and longitudinally in a large cohort of older Australian women. Method: Women in their 70s participating in the Australian Longitudinal Study on Women's Health responded in 1996 (aged 70-75) and in 1999 (aged 73-78). Cross-sectional data were analyzed for 10,063 women and longitudinal data for 6472. Self-reports were used to categorize women into four categories of physical activity at each time point as well as to define four physical activity transition categories across the 3-year period. Outcome variables for the cross-sectional analyses were the mental health component score (MCS) and mental health subscales of the Medical Outcomes Study Short Form (SF-36). The longitudinal analyses focused on changes in these variables. Confounders included the physical health component scale (PCS) of the SF-36, marital status, body mass index (BMI) and life events. Adjustment for baseline scores was included for the longitudinal analyses. Results: Cross-sectionally, higher levels of physical activity were associated with higher scores on all dependent variables, both with and without adjustment for confounders. Longitudinally, the effects were weaker, but women who had made a transition from some physical activity to none generally showed more negative changes in emotional well-being than those who had always been sedentary, while those who maintained or adopted physical activity had better outcomes. Conclusion: Physical activity is associated with emotional well-being among a population cohort of older women both cross-sectionally and longitudinally, supporting the need for the promotion of appropriate physical activity in this age group.

Cidades sob clichê imagético imaginação espacial e experimentações em poesias visuais

Esse trabalho procurou caracterizar o clichê imagético, articulando-o a exemplos relacionados às cidades provindas de pesquisas iconográficas realizadas no Google Imagens, dando-se, a partir desse contexto, se deram as rasuras dos clichês imagéticos por poesias visuais. A pesquisa iconográfica específica para a palavra “cidades” direcionou o estudo viabilizando a constatação deste clichê, que, por sua vez, foi enunciado como intermediador de imaginação espacial. As constatações empíricas sobre esta temática fez a pesquisa ser conduzida a cinco nomes de capitais brasileiras, que foram contrastadas com as imagens destas cidades caracterizadas fora do clichê imagético, sendo o formato padrão e estático da propagação das imagens foi o universo sobre o qual orbitou este estudo. Uma vez realizadas as observações sobre esta temática, passou-se à discussão poética referente às imagens captadas, e a partir de então foi feito um diálogo com artistas e poetas ao ponto de se delimitar uma justificativa para que poesias visuais fossem elaboradas rumando para outras grafias de mundo, passando, assim, a enfatizar novas possibilidades, para essas imagens identificadas como clichês. Então, este estudo visa possibilitar novas versões a serem produzidas sobre o mundo, optando pela temática “cidade” para melhor categorizar e referenciar a pesquisa iconográfica, direcionando a discussão acerca de espaços e paisagens urbanas. Para tanto, foram adotados os autores Deleuze e Guatarri, articulando seus diálogos com McLuhan e Watson, adentrando-se à dimensão do clichê e aparando-se na iconografia Google e na sua configuração repetida que então passa a evidenciar as características opostas das considerações elaboradas por Doreen Massey, para a imaginação espacial em seu processo fluídico, e não engessado. Pensando nas reverberações de dizeres que se contradizem dessas versões, a imaginação foi evidenciada para além desses processos, atentando-se, assim, às obras poéticas e artísticas de Manoel de Barros ou Valdelino Gonçalves, em que foram verificadas possibilidades de abertura de canais de diálogos com tais clichês, com poesias visuais, em um lançamento para a imaginação, rompendo-os. Em conclusão, foram observadas possibilidades de construções poéticas como dizeres de uma Geografia constituída no imaginário, mas que também possui suas significações perante a realidade, formuladas em rupturas com o dizer totalizante, repetido e homogêneo. Foram evidenciadas, então, essas características como contribuição aos estudos que tangem à temática “Geografia e Imagens”, possibilitando novas reverberações em universos de estudos para essa linha de pesquisa, que procura inovar nas percepções sobre o entendimento das imagens como canal de construção dos espaços geográficos de uma maneira geral.

Accountability and co-production of information and control: social observatories and their relationship with government agencies

Abstract:Through the development of a proposal to categorize accountability into four stages - classical, cross-sectional, systemic, and diffused -, this article aims to identify characteristics of co-production of information and socio-political control of public administration in the work of Brazilian social observatories in relationship with government control agencies. The study analyses data from 20 social observatories and, particularly, three experiences of co-production of information and control, based on a systemic perspective on accountability and a model with four categories: Political and cultural; valuing; systemic-organizational, and production. The conclusions summarize characteristics of these practices, specific phases in the accountability processes, as well as the potentialities and challenges of co-production of information and control, which not only influences, but it is also influenced by the accountability system.

Motivations which influence volunteers' satisfaction

In this paper we attempt to find out which motivations influence volunteers satisfaction. So, in a first moment, we categorize satisfaction through a factor analysis and then use linear regression models to find out the relations previously mentioned. Furthermore we analyse the existence of correlations between some demographic attributes and the other variables. In this research the population under study includes volunteers that work in the health area, more precisely volunteers that work in hospital and have direct contact with patients and their families. We obtained a total of 327 questionnaires and after excluding incomplete answers we get 304 questionnaires which embody a response rate of 36%. The outcomes of our analysis reveal that we can categorize satisfaction into intrinsic and extrinsic categories and show that motivations related to belonging and protection and career recognition are the ones influencing extrinsic satisfaction; motivations associated to development and learning and altruism are the ones with higher effect in intrinsic satisfaction. There are some negative correlations between age and extrinsic satisfaction, between years of participation and extrinsic satisfaction, between education and the motivation related to belonging and protection and between age and the motivation related to career recognition. There is only one positive correlation between hours per week and intrinsic satisfaction. The results offer new insights for research about volunteers’ motivations, motive fulfillment and volunteer satisfaction. Furthermore the outcomes advocate that to ensure satisfied volunteers, their motivations must be identified in a timely and appropriate moment, meaning that should happened as early as possible.

Le lexique fourni et interiorisé: un moyen efficace pour construire un genre ?

Cet article présente les premiers résultats d’une recherche s’intéressant à l’articulation entre imitation et invention dans l’écriture chez les jeunes scripteurs. L’étude s’attache à observer les modes de récupération de ressources textuelles fournies par les conditions de production. L’expérimentation a été conçue pour observer l’appropriation d’un genre. Des dispositifs didactiques ont été proposés à plusieurs classes de fin d’école primaire française, à partir de textes littéraires issus de la robinsonnade mis à disposition soit simultanément à l’acte d’écriture soit lors d’une seconde écriture. L’étude montre comment les élèves ont recours à deux procédés contrastés : le réinvestissement du lexique et la reformulation. Les données recueillies mettent en évidence la reprise attendue de mots caractéristiques du genre, et révèlent l’ingéniosité des scripteurs pour restructurer des matériaux langagiers. Certaines stratégies témoignent des difficultés rencontrées par les élèves qui ont eu à interpréter le lexique littéraire puis à le transférer dans leur propre récit. Des modes de reformulation différents coexistent dont on peut offrir une première catégorisation en fonction d’une appropriation plus ou moins réussie du genre considéré.

Food consumption, physical activity and socio-economic status related to BMI, waist circumference and waist-to-height ratio in adolescents

Objective: To examine the association between obesity and food group intakes, physical activity and socio-economic status in adolescents. Design: A cross-sectional study was carried out in 2008. Cole’s cut-off points were used to categorize BMI. Abdominal obesity was defined by a waist circumference at or above the 90th percentile, as well as a waist-to-height ratio at or above 0?500. Diet was evaluated using an FFQ, and the food group consumption was categorized using sex-specific tertiles of each food group amount. Physical activity was assessed via a self-report questionnaire. Socio-economic status was assessed referring to parental education and employment status. Data were analysed separately for girls and boys and the associations among food consumption, physical activity, socio-economic status and BMI, waist circumference and waist-to-height ratio were evaluated using logistic regression analysis, adjusting the results for potential confounders. Setting: Public schools in the Azorean Archipelago, Portugal. Subjects: Adolescents (n 1209) aged 15–18 years. Results: After adjustment, in boys, higher intake of ready-to-eat cereals was a negative predictor while vegetables were a positive predictor of overweight/ obesity and abdominal obesity. Active boys had lower odds of abdominal obesity compared with inactive boys. Boys whose mother showed a low education level had higher odds of abdominal obesity compared with boys whose mother presented a high education level. Concerning girls, higher intake of sweets and pastries was a negative predictor of overweight/obesity and abdominal obesity. Girls in tertile 2 of milk intake had lower odds of abdominal obesity than those in tertile 1. Girls whose father had no relationship with employment displayed higher odds of abdominal obesity compared with girls whose father had high employment status. Conclusions: We have found that different measures of obesity have distinct associations with food group intakes, physical activity and socio-economic status.
