No. of bitstreams: 1 Carlos Leonardo Figueiredo Cunha.pdf: 1098571 bytes, checksum: 29c9844e5039cc8ddc8293e37555ea15 (MD5) Previous issue date: 2010-06-24 / FUNDAÇÃO SOUSÂNDRADE DE APOIO AO DESENVOLVIMENTO DA UFMA / It was conducted a descriptive study to evaluate the use of Primary Care Services for the child population in Maranhão State with emphasis on Family Health Program in a period from July 2007 to January 2008 with a representative Maranhão State sample of 1711 children, obtained through systematic random sampling by conglomerates. It still aims to trace the evolutive parallel of some current indicators present with similar research conducted in 1996. There was the predominance of male sex, more than three years old and city residents. Demographic data pointed to mothers living with their partners (69.7%), mothers who did not work (55.3%), with low schooling level from 5 to 8 years (33.3%) and the father s schooling level from 1 to 4 years (24.9%), family income until a minimum wage (58.8%). Regarding the conditions of dwelling and sanitation, brick houses (45.9%), water supply by public company (54.4%), excreta destiny in black pit (33.9%), garbage collection (46.0%) with ownership of radio and TV (48.3%). From the total of studied children, 53.3% did have preventive consultation in the first year of life, 61.4% did not make the childcare consultation, among those who carried out the consultation it was realized in the age group from 1 to 6 months (55.8 %), by Single Health System (SHS) (92.1%), in the Basic Unit of Family Health (67.8%). The vast majority reported receiving home visits by Family Health Program (81.6%), with the realization of the child weighing (70.0%) and guidelines for their care, however great part of the mothers reported they did not have orientation regarding the cares face the diarrheas (92.4%). Although the vast majority has the child card (86.8%), the register of child weighing was observed only in an intermediate percentage of them (50.5%) performed most times by the Health Community Agent (53.9 %). The data found out were compared to data from the research "Health, Nutrition and Infant Mortality in Maranhão, developed in 1996 and it was observed that virtually all variables showed positive increasing - focus on improving of the mother s schooling level (from 47% to 63.6% of mothers with more than 4 years of study), reducing the percentage of mothers with no schooling (from 24.4% to 11.3%), appropriate excreta destination (from 25.8% to 32.8%) and the financing of these consultations by SHS (from 78.6% to 92.1%). With this analysis, it emphasizes the improvement of some quality of life indicators and the attention to child health in Maranhão State, although they are not uniform in reduction much needed of infant mortality. / Realizou-se um estudo descritivo com o objetivo de avaliar a utilização dos serviços de Atenção Básica pela população infantil no Estado do Maranhão com ênfase no Programa Saúde da Família no período de julho de 2007 a janeiro de 2008 com uma amostra representativa do estado do Maranhão de 1.711 crianças, obtida por amostragem aleatória sistemática por conglomerados. Objetiva-se ainda traçar paralelo evolutivo de alguns indicadores atuais com a pesquisa similar realizada em 1996. Houve predomínio do sexo masculino, de três e mais anos de idade e residentes na zona urbana. Os dados demográficos apontaram para mães que vivem com seus companheiros (69,7%), que não trabalham (55,3%), com escolaridade de 5 a 8 anos (33,3%) e do pai de 1 a 4 anos (24,9%), renda familiar de até um salário mínimo (58,8%). Quanto às condições de moradia e saneamento, casas de tijolo (45,9%), abastecimento de água pela rede pública (54.4%), destino dos dejetos em fossa negra (33,9%), lixo coletado (46,0%), com posse de rádio e TV (48,3%). Do total de crianças estudadas, 53,3% realizaram a consulta preventiva no 1º ano de vida, 61,4% não fizeram a consulta de puericultura, dentre as que realizaram, a consulta foi realizada na faixa etária de 1 a 6 meses (55,8%), no SUS (92,1%), em Unidade Básica de Saúde da Família (67,8%). A grande maioria relatou visitas domiciliares pelo Programa Saúde da Família (81,6%), com a realização da pesagem da criança (70,0%) e orientações em relação aos seus cuidados, porém grande parte das mães relatou a não orientação em relação aos cuidados frente às diarréias (92,4%). Apesar da maioria possuir o cartão da criança (86,8%), o registro de peso só foi observado em (50,5%) realizado na maioria das vezes pelo Agente Comunitário de Saúde (53,9%). Os dados encontrados fora comparados aos dados da pesquisa Saúde, Nutrição e Mortalidade Infantil no Maranhão , desenvolvida em 1996, e observou-se que praticamente todas as variáveis sofreram incremento positivo - destaque para melhoria da escolaridade da mãe (de 47% para 63,6% de mães com mais de 4 anos de estudo) com redução do percentual de mães sem escolaridade (de 24,4% para 11,3%), destino adequado dos dejetos (de 25,8% para 32,8%) e o financiamento dessas consultas pelo SUS (de 78,6% para 92,1%). Com essa análise, ressalta-se a melhoria em alguns indicadores de qualidade de vida e da atenção a saúde da criança no estado do Maranhão, apesar de não serem uniformes na redução tão necessária da morbimortalidade infantil.

With various new alternatives of low-cost sensor devices, there is a strong demand for large scale wireless sensor networks (WSN). Energy efficiency in routing is crucial for achieving the desired levels of longevity in these networks. Existing routing algorithms that do not combine information on transmission energies on links, residual energies at nodes, and the identity of data itself, cannot reach network capacity. A proof-of-concept routing algorithm that combines data aggregation with the minimum-weight path routing is studied in this thesis work. This new algorithm can achieve much larger network lifetime when there is redundancy in messages to be carried by the network, a practical reality in sensor network applications.

Today, web sites are important communication channels that reach a wide group of people. Measuring the effectiveness of these web-sites has become a key issue for researchers as well as practitioners. However, there is no consensus on how to define web site effectiveness and which dimensions need to be used for the evaluation of these web sites. This problem is more noteworthy for information driven web sites like academic web sites. There is limited academic literature in this predominant application area. The existing studies measured the effectiveness of these academic web sites by taking into account their information architecture mostly using think-aloud methodology. However, there is limited study on web analytics tools which are capable of providing valuable information regarding the web site users such as their navigation behaviours and browser details. Although web analytics tools provide detailed and valuable information, the existing studies have utilized their very basic features. In this thesis, we have explored web analytic tools and think-aloud study method to improve information architecture of web sites. Taking METU Informatics Institute web site as a case study, we have used the reports of Google Analytics which is a commercial web analytics tool owned by Google and think-aloud study results to improve the information architecture of our case study web-site.

Objectif : L’objectif général de cette étude est de comprendre en quoi l’utilisation des services de santé et de disponibilité des ressources en santé au Québec sont équitables. Méthodes : De type transversal et corrélationnel, cette étude intéresse les 95 territoires CSSS du Québec, et couvre les années 2006-2007 et 2008-2009. L’indice de défavorisation matérielle et sociale de Pampalon est mis en lien avec deux séries de variables, soit celles d’utilisation des services par CSSS (services hospitaliers; services médicaux; services CLSC) et celles de disponibilité des ressources (capacité financière; capacité matérielle, capacité humaine; viabilité). Pour ce faire, des analyses de variance ont été effectuées. Le modèle intégrateur de la performance des services de santé EGIPSS et celui de l’utilisation des services de santé de Donabedian servent de cadre d’analyse. Résultats : L’utilisation des services de santé est équitable en ce qui concerne la défavorisation matérielle, mais pas en ce qui a trait à la défavorisation sociale. L’utilisation des services médicaux dispensés par les omnipraticiens est plus élevée chez les populations les plus favorisées socialement comparativement aux populations les plus défavorisées. Toutefois, l’utilisation des médecins spécialistes est plus équitable que celle des omnipraticiens, cela, chez les populations défavorisées autant matériellement que socialement. Les hospitalisations évitables sont plus élevées chez les populations les défavorisées socialement comparativement aux populations les plus favorisées. En termes de disponibilité des ressources, les populations défavorisées disposent de plus de ressources que les plus favorisées, sauf en ce qui concerne la répartition du personnel. Conclusion : En général, il existe très peu d’iniquités dans l’utilisation des services de santé au Québec. Par ailleurs, la disponibilité des ressources en santé est relativement équitable au Québec, exception faite de la disponibilité du personnel. / Objectives: The general objective of this study is to understand in what the use of health services and the availability of health resources in Quebec are fair. Methods: This cross-sectional and corelational study interests the 95 territories CSSS of Quebec, and covers the years 2006-2007 and 2008-2009. The material and social deprivation index of Pampalon is put in connection with two series of variables, such those of the use of the services by CSSS (hospital services; medical services; CLSC services) and those of availability of the resources (financial capacity; material capacity, human capacity; viability). To do it, analyses of variance were made. The integrative model of the health service performance (EGIPSS) and that of the use of the health services of Donabedian serve as frame of analysis. Results: The use of health services is fair as regards the material deprivation, but not in what concerned the social deprivation. The use of medical services dispensed by the general practitioners is more raised at the population the most favored socially compared with the most disadvantaged population. However, the use of the specialists is fairer than that of the general practitioners, it, for the populations disadvantaged so materially as socially. The avoidable hospitalizations are more raised at the population the most disadvantaged socially compared with the most favored. In terms of the availability of resources, the disadvantaged populations have more resources than the most favored populations. Conclusion: Generally, there are very few inequities in the use of health services in Quebec. Besides, the availability of the resources regarding health is relatively fair in Quebec, exception made by the distribution of the staff.

Free cervical cancer screening services are provided in Malawi’s public healthcare institutionssince 1999. Few women aged 42 and older, utilise these services. Cervical cancer continues to be a major cause of morbidity and mortality among this group of women. Structured interviews were conducted with 381 women who attended three healthcare centers in Blantyre and semi-structured interviews with 14 nurse/midwives working at the same centers. The results for both phases arepresented within the Health Belief Model’s constructs. Phase 1 revealed that women had low levels of perceived susceptibility to cervical cancer. Although the interviewed women perceived cervical cancer to be a serious condition, they did not regard themselves to be at risk of suffering from cervical cancer. Knowledge that cervical cancer screening could detect this cancer at an early stage, embarrassment, stigma, social support, financial costs, traditional practices and available sources of information, influenced women’s intentions to be screened for cervical cancer. In phase 2, the nurse/midwives indicated that Malawian women lacked information about cervical cancer, available screening tests and the purpose of such screening.These women perceived cervical canceras being incurable and linked to witchcraft. Women’s utilisation of cervical screening services was hampered by barriers relating to healthcare institutions, women themselves and nurse/midwives. Local radio and television broadcasts, friends and nurse/midwives motivated individual women to use these screening services.Women preferred receiving information about cervical cancer screening during community activities. Health education should be intensified, nurse/midwives should be more empathetic, clinic days and hours should be extended. Misconceptions should be addressed and more service providers should be trained. This would enable more Malawian women to use cervical screening services, enhancing early detection and treatment of cervical cancer and reducing the morbidity and mortality statistics related to this condition in Malawi. / Health Studies / D.

L’utilisation des services de santé est au centre de l’organisation des soins. La compréhension des processus qui déterminent cette utilisation est essentielle pour agir sur le système de santé et faire en sorte qu’il réponde mieux aux besoins de la population. L’objectif de cette thèse est de comprendre le phénomène complexe qu’est l’utilisation des services de santé en s’intéressant à la pratique des médecins omnipraticiens. En nous appuyant sur le cadre théorique de Donabedian, nous décomposons les déterminants de l’utilisation des services de santé en trois niveaux : le niveau individuel, le niveau organisationnel, et le niveau environnemental. Pour tenir compte de la complexité des phénomènes de cette étude nous proposons de nous appuyer sur l’approche configurationnelle. Notre question de recherche est la suivante : dans quelle mesure le mode d’exercice des omnipraticiens influence-t-il la prestation des services et comment l’environnement géographique et la patientèle modulent-ils cette relation ? Nous avons utilisé des bases de données jumelées du Collège des médecins du Québec, de la Régie d’assurance maladie du Québec et de la banque de données iCLSC. Notre échantillon est constitué des médecins omnipraticiens de l’année 2002, ayant satisfait aux critères d’inclusion, ce qui représente près de 70% de la population totale. Des analyses de correspondances multiples et des classifications ascendantes hiérarchiques ont été utilisées pour réaliser la taxonomie des modes d’exercice et des contextes géographiques. Nous avons construit des indicateurs d’utilisation des services de santé pour apprécier la continuité, la globalité, l’accessibilité et la productivité. Ces indicateurs ont été validés en les comparant à ceux d’une enquête populationnelle. Nous présentons tout d’abord les modes d’exercice des médecins qui sont au nombre de sept. Deux modes d’exercice à lieu unique ont émergé : le mode d’exercice en cabinet privé d'une part, caractérisé par des niveaux de continuité et productivité élevés, le mode d’exercice en CLSC d'autre part présentant un niveau de productivité faible et des niveaux de globalité et d'accessibilité légèrement au-dessus de la moyenne. Dans les cinq autres modes d’exercice, les médecins exercent leur pratique dans une configuration de lieux. Deux modes d’exercice multi-institutionnel réunissent des médecins qui partagent leur temps entre les urgences, les centres hospitaliers et le cabinet privé ou le CLSC. Les médecins de ces deux groupes présentent des niveaux d’accessibilité et de productivité très élevés. Le mode d’exercice le moins actif réunit des médecins travaillant en cabinet privé et en CHLSD. Leur niveau d’activité est inférieur à la moyenne. Ils sont caractérisés par un niveau de continuité très élevé. Le mode d’exercice ambulatoire regroupe des médecins qui partagent leur pratique entre le CLSC, le cabinet privé et le CHLSD. Ces médecins présentent des résultats faibles sur tous les indicateurs. Finalement le mode d’exercice hospitaliste réunit des médecins dont la majorité de la pratique s’exerce en milieu hospitalier avec une petite composante en cabinet privé. Dans ce mode d’exercice tous les indicateurs sont faibles. Les analyses ont mis en évidence quatre groupes de territoires de CSSS : les ruraux, les semi-urbains, les urbains et les métropolitains. La prévalence des modes d’exercice varie selon les contextes. En milieu rural, le multi-institutionnel attire près d’un tiers des médecins. En milieu semi-urbain, les médecins se retrouvent de façon plus prédominante dans les modes d’exercice ayant une composante CLSC. En milieu urbain, les modes d’exercice ayant une composante cabinet privé attirent plus de médecins. En milieu métropolitain, les modes d’exercice moins actif et hospitaliste attirent près de 40% des médecins. Les omnipraticiens se répartissent presque également dans les autres modes d’exercice. Les niveaux des indicateurs varient en fonction de l’environnement géographique. Ainsi l’accessibilité augmente avec le niveau de ruralité. De façon inverse, la productivité augmente avec le niveau d’urbanité. La continuité des soins est plus élevée en régions métropolitaines et rurales. La globalité varie peu d’un contexte à l’autre. Pour pallier à la carence de l’analyse partielle de l’organisation de la pratique des médecins dans la littérature, nous avons créé le concept de mode d’exercice comme la configuration de lieux professionnels de pratique propre à chaque médecin. A notre connaissance, il n’existe pas dans la littérature, d’étude qui ait analysé simultanément quatre indicateurs de l’utilisation des services pour évaluer la prestation des services médicaux, comme nous l’avons fait. Les résultats de nos analyses montrent qu’il existe une différence dans la prestation des services selon le mode d’exercice. Certains des résultats trouvés sont documentés dans la littérature et plus particulièrement quand il s’agit de mode d’exercice à lieu unique. La continuité et la globalité des soins semblent évoluer dans le même sens. De même, la productivité et l’accessibilité sont corrélées positivement. Cependant il existe une tension, entre les premiers indicateurs et les seconds. Seuls les modes d’exercice à lieu unique déjouent l’arbitrage entre les indicateurs, énoncé dans l’état des connaissances. Aucun mode d’exercice ne présente de niveaux élevés pour les quatre indicateurs. Il est donc nécessaire de travailler sur des combinaisons de modes d’exercice, sur des territoires, afin d’offrir à la population les services nécessaires pour l’atteinte concomitante des quatre objectifs de prestation des services. Les modes d’exercice émergents (qui attirent les jeunes médecins) et les modes d’exercice en voie de disparition (où la prévalence des médecins les plus âgés est la plus grande) sont préoccupants. A noter que les modes d’exercice amenés à disparaître répondent mieux aux besoins de santé de la population que les modes d’exercice émergents, au regard de tous nos indicateurs. En conclusion, cette thèse présente trois contributions théoriques et trois contributions méthodologiques. Les implications pour les recherches futures et la décision indiquent que, si aucune mesure n’est mise en place pour renverser la tendance, le Québec risque de vivre des pénuries dans la prestation des services en termes de continuité, globalité et accessibilité. / Health services utilization is central to healthcare organization. Understanding the processes that determine utilization is essential to influence the health system and to ensure that it better meets the needs of the population. The objective of this thesis is to understand the complex phenomenon of health services utilization by looking at general practitioners' practices. Using Donabedian's theoretical framework, we decomposed determinants of utilization at three levels: individual, organizational and environmental. We chose a configurational approach to account for the complex nature of the phenomenon under study. Our question is the following: To what extent does the type of practice influence delivery of health services, and how do geographical environment and patient populations mediate this relationship? We used combined data sources from the Collège des médecins du Québec, the Régie de l'assurance maladie du Québec and the iCLSC databases. Almost 70% of family physicians practicing in 2002 met the selection criteria. Multiple correspondence analyses and ascending hierarchical classifications were used to create a taxonomy of practices and a taxonomy of geographical contexts. We constructed services utilization indicators to assess continuity, comprehensiveness, accessibility and productivity. These indicators were validated using a population survey. The results first present physicians' profiles of practice. Two single-site profiles emerged. Private clinic practice is characterized by high levels of continuity and productivity. CLSC practice is typified by low productivity level and slightly above average levels of comprehensiveness and accessibility. Five other practice profiles include physicians who practice in different combinations of sites (multi-sites profiles). Two multi-institutional profiles of practice include physicians who divide their time in two different patterns, among emergency departments, hospital centres and private clinics or CLSCs. The levels of accessibility and productivity for physicians in these two groups are very high. The profile combining private clinics and long-term care facilities (the less active profile) includes physicians with below average productivity, and very high level of continuity. An ambulatory practice profile includes physicians who work in CLSCs, private clinics and long-term care facilities. Physicians in this profile, show low levels for all indicators. Finally, the hospital-based practice includes physicians who practice mainly in hospitals but also occasionally in private clinics. Our analyses highlighted four groups of CSSS territories: rural, semi-urban, urban, and metropolitan. The prevalence of practice profiles vary based on context. In rural settings, about a third of physicians opt for multi-institutional practices. In semi-urban settings, physicians predominantly work in practices that include a CLSC component. In urban settings, more physicians choose a profile of practice with a private clinic component. Finally, in metropolitan areas, the less active and more hospital-based type of practice attracts close to 40% of physicians. General practitioners are almost equally split among the other profiles of practices. Indicator levels vary according to geographical environment. As a result, accessibility increases with level of rurality. Conversely, productivity increases with level of urbanity. Continuity of care is higher in metropolitan and rural areas. Comprehensiveness changes little among contexts. We will refer back to the initial research question to look at the results and compare them with the literature. To offset the shortcomings of the limited analysis of physicians' practice organization found in the literature, we defined type of practice concept as the configuration of each physician's professional practice site To our knowledge, no other study reported in the literature has analyzed four service utilization indicators simultaneously to assess delivery of medical services. Results of our analyses show that there is a difference in service delivery based on type of practice. Some results are documented in the literature, especially as regards single-site type of practice. We will then present the relationships among indicators. Care continuity and comprehensiveness seem to be evolving in the same direction. Productivity and accessibility are also positively correlated. However, there is a certain tension between the former and the latter indicators. Only single-site types do not fit the indicators, as articulated in the state of current knowledge. No type of practice showed high levels for the four indicators. It is therefore necessary to work on combinations of practice types in the territories to offer the population the services required to reach all four care delivery objectives. Emerging types of practice (which attract young doctors) and those that are dying out (where the prevalence of older physicians is highest) are discussed in the next section. It should be noted that the types of practice that are vanishing address the population's health needs better than emerging types, in terms of indicators. In conclusion, this thesis presents three theoretical and three methodological contributions. The implications for future research and decision making point out that if no measures are implemented to reverse the trend, Quebec risks to see deficiencies in delivery of services in terms of continuity, comprehensiveness and accessibility.

Knowledge that cervical cancer screening could detect this cancer at an early stage, embarrassment, stigma, social support, financial costs, traditional practices and available sources of information, influenced women’s intentions to be screened for cervical cancer. In phase 2, the nurse/midwives indicated that Malawian women lacked information about cervical cancer, available screening tests and the purpose of such screening.These women perceived cervical canceras being incurable and linked to witchcraft. Women’s utilisation of cervical screening services was hampered by barriers relating to healthcare institutions, women themselves and nurse/midwives. Local radio and television broadcasts, friends and nurse/midwives motivated individual women to use these screening services.Women preferred receiving information about cervical cancer screening during community activities. Health education should be intensified, nurse/midwives should be more empathetic, clinic days and hours should be extended. Misconceptions should be addressed and more service providers should be trained. This would enable more Malawian women to use cervical screening services, enhancing early detection and treatment of cervical cancer and reducing the morbidity and mortality statistics related to this condition in Malawi. / Health Studies / D.

Subjects with 60 or more years old, living in Juiz de For a and who attended a vaccination station in the city during the National Immunization Campaign Against Influenza of 2006 were eligible for study. The main results showed social and health profiles similar to that described for the Brazilian population. Women had poorer self-rated health, higher proportion of morbidity and use of medication and a higher proportion and frequency of medical visits compared to men. The prevalence of non-use of mammography in this population was 27,9%, and advanced age, poor education, lack of marital relationship, lack of Pap smear and no consultations with gynecologists were associated to a higher risk of non-use. The main reasons why women have never undergone mammography were "Having no need of a mammogram", "Not having received medical advice to have a mammogram" and “Having negative affects in relation to mammograms”.
