Auxílio na prevenção de doenças crônicas por meio de mapeamento e relacionamento conceitual de informações em biomedicina / Support in the Prevention of Chronic Diseases by means of Mapping and Conceptual Relationship of Biomedical Information

Juliana Tarossi Pollettini 28 November 2011 (has links)
Pesquisas recentes em medicina genômica sugerem que fatores de risco que incidem desde a concepção de uma criança até o final de sua adolescência podem influenciar no desenvolvimento de doenças crônicas da idade adulta. Artigos científicos com descobertas e estudos inovadores sobre o tema indicam que a epigenética deve ser explorada para prevenir doenças de alta prevalência como doenças cardiovasculares, diabetes e obesidade. A grande quantidade de artigos disponibilizados diariamente dificulta a atualização de profissionais, uma vez que buscas por informação exata se tornam complexas e dispendiosas em relação ao tempo gasto na procura e análise dos resultados. Algumas tecnologias e técnicas computacionais podem apoiar a manipulação dos grandes repositórios de informações biomédicas, assim como a geração de conhecimento. O presente trabalho pesquisa a descoberta automática de artigos científicos que relacionem doenças crônicas e fatores de risco para as mesmas em registros clínicos de pacientes. Este trabalho também apresenta o desenvolvimento de um arcabouço de software para sistemas de vigilância que alertem profissionais de saúde sobre problemas no desenvolvimento humano. A efetiva transformação dos resultados de pesquisas biomédicas em conhecimento possível de ser utilizado para beneficiar a saúde pública tem sido considerada um domínio importante da informática. Este domínio é denominado Bioinformática Translacional (BUTTE,2008). Considerando-se que doenças crônicas são, mundialmente, um problema sério de saúde e lideram as causas de mortalidade com 60% de todas as mortes, o presente trabalho poderá possibilitar o uso direto dos resultados dessas pesquisas na saúde pública e pode ser considerado um trabalho de Bioinformática Translacional. / Genomic medicine has suggested that the exposure to risk factors since conception may influence gene expression and consequently induce the development of chronic diseases in adulthood. Scientific papers bringing up these discoveries indicate that epigenetics must be exploited to prevent diseases of high prevalence, such as cardiovascular diseases, diabetes and obesity. A large amount of scientific information burdens health care professionals interested in being updated, once searches for accurate information become complex and expensive. Some computational techniques might support management of large biomedical information repositories and discovery of knowledge. This study presents a framework to support surveillance systems to alert health professionals about human development problems, retrieving scientific papers that relate chronic diseases to risk factors detected on a patient\'s clinical record. As a contribution, healthcare professionals will be able to create a routine with the family, setting up the best growing conditions. According to Butte, the effective transformation of results from biomedical research into knowledge that actually improves public health has been considered an important domain of informatics and has been called Translational Bioinformatics. Since chronic diseases are a serious health problem worldwide and leads the causes of mortality with 60% of all deaths, this scientific investigation will probably enable results from bioinformatics researches to directly benefit public health.

Terveysvalmennuksen vaikuttavuus paljon terveyspalveluita käyttäville asiakkaille perusterveydenhuollossa

Kivelä, K. (Kirsi) 03 December 2019 (has links)
Abstract The purpose of the study was to describe and evaluate the effectiveness of health coaching on health promotion (health-related quality of life, adherence to health regimens, clinical health outcomes and lifestyle factors) among frequent attenders of primary healthcare. The aim was to generate new information to promote frequent attenders’ health and to improve the care and education of patients with chronic diseases. The study consisted of three sub studies. A systematic literature review (sub study I) described the effects of health coaching on adult patients with chronic diseases. The data were collected from the databases and through a manual search. The data (n=13) were analyzed using narrative synthesis. Conceptual analysis (sub study II) identified frequent attenders of primary healthcare. The data were collected from databases and through a manual search. The data (n=59) were analyzed using synthesis and content analyses. The quasi-experimental research method (sub study III) evaluated the effectiveness of health coaching among frequent attenders (n=110) in primary healthcare. The experimental group received the health coaching and the control group received the usual care. The data were collected before the intervention and 12 months afterwards using a questionnaire on FINRISKI2012, RAND-36 and ACDI and clinical health outcomes measured by health-coaching nurses. The data were analyzed using statistical methods. According to the systematic review, health coaching produced positive effects on patients’ physiological, psychological and behavioural conditions and on their social life. In particular, weight management, physical and mental status improved, and physical activity increased. Conceptual analysis identified four attributes of frequent attenders: the feelings of symptoms, perceived poor health status, lower quality of life and frequent visits to a primary healthcare provider. Health coaching had statistically significant effects on the blood pressure and health-related quality of life among the experimental group, especially in emotional role limitation and energy during the 12 months. There were no statistically significant differences between the experimental and control groups on health-related quality of life, adherence to health regimens and lifestyle factors. / Tiivistelmä Tutkimuksen tarkoituksena oli kuvata ja arvioida terveysvalmennuksen vaikuttavuutta perusterveydenhuollon paljon terveyspalveluita käyttävien asiakkaiden terveyden edistämiseen (terveyteen liittyvään elämänlaatuun, hoitoon sitoutumiseen, kliiniseen terveydentilaan ja elintapoihin). Tavoitteena oli tuottaa uutta tietoa paljon terveyspalveluita käyttävien asiakkaiden terveyden edistämiseen ja pitkäaikaissairaiden hoidon ja ohjauksen kehittämiseen. Tutkimus koostui kolmesta osatutkimuksesta. Systemaattisella kirjallisuuskatsauksella (osatutkimus I) kuvattiin terveysvalmennuksen vaikutuksia pitkäaikaissairaille. Aineisto kerättiin viitetietokannoista ja manuaalisella haulla. Aineisto (n=13) analysoitiin narratiivisella synteesillä. Käsiteanalyysilla (osatutkimus II) määriteltiin paljon terveyspalveluita käyttävä asiakas perusterveydenhuollossa. Aineisto kerättiin viitetietokannoista ja manuaalisella haulla. Aineisto (n=59) analysoitiin synteesillä ja sisällönanalyysilla. Kvasikokeellisella tutkimusmenetelmällä (osatutkimus III) arvioitiin terveysvalmennuksen vaikuttavuutta perusterveydenhuollon paljon terveyspalveluita käyttäville asiakkaille (n=110). Koeryhmä sai terveysvalmennusta ja kontrolliryhmä tavanomaista hoitoa. Aineisto kerättiin FINRISKI 2012-, RAND-36- ja ACDI-kyselylomakkeilla sekä kliinisen terveydentilan mittauksilla ennen ja 12 kuukautta intervention jälkeen. Aineisto analysoitiin tilastomenetelmin. Kirjallisuuskatsauksen mukaan terveysvalmennuksella oli positiivisia vaikutuksia pitkäaikaissairaiden fyysisiin, psyykkisiin, sosiaalisiin ja käyttäytymistekijöihin. Erityisesti painonhallinta sekä fyysinen ja psyykkinen terveydentila paranivat ja fyysinen aktiivisuus lisääntyi. Käsiteanalyysilla tunnistettiin neljä ominaispiirrettä perusterveydenhuollon paljon terveyspalveluita käyttävälle asiakkaalle: oireiden tunne, kokemus terveydentilan heikkenemisestä, alhaisempi elämänlaatu ja useat käynnit perusterveydenhuollossa. Terveysvalmennusinterventio edisti tilastollisesti merkitsevästi koeryhmän terveyteen liittyvän elämänlaadun psyykkisistä syistä johtuvien ongelmien roolitoimintaa, tarmokkuutta ja verenpainetta 12 kuukauden aikana. Koe- ja kontrolliryhmän välillä ei havaittu tilastollisesti merkitseviä eroja terveyteen liittyvässä elämänlaadussa, hoitoon sitoutumisessa ja elintavoissa.

Factores sociodemográficos asociados a recibir tratamiento para enfermedades crónicas en pacientes migrantes venezolanos en el Perú: análisis secundario de la ENPOVE 2018 / Association of Sociodemographic factors with receiving treatment for chronic diseases among Venezuelan migrants in Peru: A secondary analysis of ENPOVE 2018

Mendoza Rivera, Samantha Elisa, Quevedo Ramirez, Andrés Ernesto 01 December 2021 (has links)
Introducción: Además de tener acceso limitado a los servicios de salud, la población migrante es vulnerable a problemas de salud tales como enfermedades crónicas. Considerando la masiva migración venezolana al Perú se evaluó la asociación entre factores sociodemográficos y recibir tratamiento para enfermedades crónicas en pacientes migrantes venezolanos según la “Encuesta Dirigida a la Población Venezolana que Reside en el País” - ENPOVE 2018. Métodos: Estudio transversal analítico basado en un análisis secundario de ENPOVE 2018. El estudio incluyó a todo migrante venezolano con 18 años a más que tuvieran enfermedades crónicas de cualquier tipo. El desenlace fue haber recibido tratamiento para la enfermedad crónica que padece. Se usó Regresión de Poisson para obtener razones de prevalencia crudas y ajustadas (RPa) considerando el muestreo complejo. Resultados: Un total de 865 personas con enfermedades crónicas fueron incluidas; de estos 21.98% recibió tratamiento. La media de edad fue 36.6 años, 41.8% fueron hombres, y 92.7% no tenían seguro de salud. Recibir tratamiento se asoció a ser viudo/divorciado/ex conviviente (RPa:1.87; IC95%:1.16-3.03) respecto a los convivientes/casados. Estar afiliado a cualquier tipo de seguro de salud aumentó la probabilidad de recibir tratamiento (RPa:1.85; IC95%:1.19-2.88). Para enfermedad crónica metabólica, solo se encontró asociación con estar afiliado a cualquier tipo de seguro (RPa:2.26; IC95%:1.17-4.39). Conclusión: El estar afiliado a cualquier seguro de salud estuvo asociado tanto a recibir tratamiento para cualquier enfermedad crónica como para enfermedad crónica metabólica. Estos resultados resaltan la necesidad de brindar aseguramiento en salud a las poblaciones vulnerables, como migrantes. / Background: Migrants have limited access to healthcare and are particularly vulnerable to health problems like chronic diseases. Considering the massive migration from Venezuela to Peru, the aim of this study is to assess the association of sociodemographic factors with receiving treatment for chronic diseases among Venezuelan migrants according to “Encuesta Dirigida a la Población Venezolana que Reside en el País” - ENPOVE 2018. Methods: A cross-sectional study based on a secondary analysis from ENPOVE 2018 was conducted. We included all Venezuelan migrants ≥18 years old with chronic diseases of any kind. The outcome was to receive treatment for the chronic disease that the patient suffers. Crude and adjusted prevalence ratios (aPR) were obtained using Poisson regression corrected by complex sampling. Results: We included 865 migrants with chronic diseases; from whom, 21.98% received treatment. Mean age was 36.6 years old, 41.8% were male, and 92.71% did not have health insurance. Receiving treatment was associated with being widow/divorced/ex-partner (aPR:1.87; 95%CI:1.16-3.03) compared with being married or in a partnership. Having health insurance increased the probability of receiving treatment (aPR:1.85; 95%CI:1.19-2.88). For chronic metabolic diseases, receiving treatment was only associated with having health insurance (aPR:2.26; 95%CI:1.17-4.39). Conclusion: Having health insurance was associated with receiving treatment for any chronic disease and for metabolic chronic diseases. These results highlight the need of offering health insurance to vulnerable populations, like migrants. / Tesis

Exercise compliance and health outcome in a chronic disease management programme

Du Plessis, Riana 07 October 2010 (has links)
In the latter part of the 20th century chronic diseases, especially cardio vascular-related diseases (CVDs) and Type 2 diabetes mellitus (DM) seemed to have emerged as substantial problems. This can be seen in the prevalence and the cost of CVDs in South Africa and worldwide. It was predicted that by the year 2030 more people would be dying from CVDs than from Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/Aids). The reasons for the occurrence of CVDs are linked to biological (i.e. hypertension, hyperlipidemia, obesity, insulin resistance, etc), psychological (i.e. emotional stress), and behavioural or lifestyle risk factors. It is known that physical exercise can aid in the treatment of CVDs. Institutions such as the American College of Sports Medicine (ACSM) recommended an exercise frequency of three times per week for 20 minutes. According to literature, a third of patients in exercise studies do not comply with their exercise protocol, and after three to six months, 50 percent will drop out of organised training groups. Less than a third of South Africans complied with exercising 30 minutes a day on most days of the week. Thus, there has been much interest among health-care providers to manage exercise compliance. Exercise compliance is a complex construct, and thus in the present study the role that behavioural patterns play was also investigated via psychological behavioural models. The major objectives of the study were the following: <ul> <li> Firstly, to determine if exercise compliance or non-compliance had an influence on shifts measured in the clinical parameters (i.e. blood pressure, blood lipid levels, blood glucose levels, body mass index, body fat percentage and cardiac risk percentage) over time.</li> <li> Secondly, to determine whether there were any correlation between the psychological behavioural models and the exercise compliance of the members over the course of the Best Med/Access Health-Disease Management Programme (BM/AH-DM Programme).</li></ul> In the present study, a retrospective data analysis was done on data collected from Best Med Medical Aid members (n = 400) who participated in a chronic disease management programme for three and a half years. The inclusion criteria for participation on the programme were the presence of one or more of the following CVDs namely: hypercholesterolemia, hypertension and DM. The members’ clinical parameters (height, body weight, body fat percentage, blood pressure, finger-prick non-fasting (random) blood cholesterol level, finger-prick non-fasting (random) blood glucose, sub-maximal V02 fitness test) were measured every three months. After a baseline assessment was done, an exercise programme was given to each member and a norm of exercising twice a week was prescribed. If members adhered to the norm they were considered compliant and if they did not adhere to the norm, they were considered as being non-compliant. Their exercise compliance, and relevant clinical parameters were measured over 30 months, although data analysis was only a reflection of the first 12 months’ data. At the beginning of the BM/AH-DM Programme the members’ Level of Readiness (LOR) to make a lifestyle change was measured via a questionnaire and by the end of the programme they completed an Implicit Theory Scale (ITS) questionnaire. Descriptive statistics (means, standard deviation) were used to determine the entire groups’ compliance, and to divide the group into compliant and noncompliant groups. The T-test or the Mann-Whitney Test (an equivalent nonparametric technique) was applied to determine significant differences between groups. Thus did the clinical parameters measured over time (baseline to 3 months, baseline to 6 months and baseline to 12 months), change more in the compliant than in the non-compliant group? And were there correlations between psychological questionnaires answers and the two exercise groups? The results indicated that the group’s exercise compliance trend decreased drastically over time. Statistical significant decreases were demonstrated in systolic (p = 0.007) and diastolic (p = 0.012) blood pressure, BMI (p = 0.072 and p = 0.0003), cardiac risk percentage (p = 0.003), and body weight (p = 0.003 and p = 0.0000). All of these decreases were seen in the exercise compliant group. There were no statistical correlations between the psychological questionnaires and the exercise groups. Limitations were the quality of the clinical data, the exercise compliance data that deteriorated over time, and the LOR and ITS questionnaires was neither valid nor reliable tools in making predictions regarding exercise behaviour/compliance. For future research it is recommended that measurements of blood pressure and cholesterol be done more thoroughly, and dietary fat intake must be monitored. A valid and reliable cardiac risk tool, LOR and ITS questionnaires must be designed. AFRIKAANS : Die voorkoms en kosteïmplikasies van kroniese siektetoestande in Suid–Afrika en wêreldwyd, het in die laaste gedeelte van die 20ste eeu ‘n wesenlike probleem geword. Kardiovaskulêre (KVS) siektes en tipe 2 diabetes mellitus (DM) is veral voorbeelde van sulke siektetoestande. Daar is voorspel dat in die jaar 2030, meer mense wêreldwyd aan KVS sal doodgaan, as aan Menslike Immuniteitsgebrekvirus/Verworwe Immuniteitsgebreksindroom (MIV/Vigs). Die risikofaktore wat met die oorsake van KVS geassosieer word, is die volgende: <ul> <li> Biologiese (met inbegrip van hipertensie, insulienweerstandigheid, hoë bloedcholesteroltellings, ens)</li> <li> Sielkundige (bv emosionele spanning) • Risikofaktore wat verband hou met lewenstyl.</li></ul> Literatuur bevestig dat fisiese oefening help om KVS en diabetes mellitus te behandel. Die American College of Sports Medicine (ACSM) het ‘n oefenriglyn van drie maal per week vir 20 minute lank as ‘n minimumfrekwensie daargestel. Volgens literatuur oefen ‘n derde van pasiënte wat deelneem aan oefeningnavorsingsstudies nie volgens die riglyne wat gestel word nie en binne die eerste drie tot ses maande sal 50% van die pasiënte ophou oefen. Navorsing wat op die Suid-Afrikaanse bevolking gedoen is, toon dat minder as ‘n derde 30 minute lank op meeste dae van die week oefen. Dus is die belangstelling van gesondheidsterapeute rakende die bestuur van gereelde oefeningdeelname geprikkel. Gereelde oefeningdeelname sluit ook die rol van gedragspatrone in en dus is sielkundige gedragsmodelle gebruik om dit ook in die huidige studie te ondersoek.

L'empathie clinique : rôle et déterminants dans la prise en charge des maladies chroniques graves / Clinical empathy : role and determinants in the care of severe chronic diseases

Robieux, Léonore 15 November 2017 (has links)
Ces 15 dernières années, la recherche sur l'empathie clinique dans le contexte de la médecine somatique s'est développée de manière significative. Cette empathie clinique est donc de mieux en mieux cernée : élaboration de différentes modélisations et identification de ses bénéfices. Aujourd'hui, il reste certains challenges à relever, et notamment celui d'améliorer et de préserver l'empathie clinique au fil de la formation et de la pratique médicales tout en protégeant le bien-être des médecins. Ce travail de thèse a pour objectif de définir l'empathie clinique dans le cadre des maladies chroniques graves : son processus, ses déterminants, ses conséquences et les ressources nécessaires. Ce travail propose trois études successives portant sur des patients (N=15) et des médecins hospitaliers (N=235) selon un design mixte, recueils de données quantitatifs et qualitatifs associés à des analyses de données quantitatives. Ces études cherchent à définir l'empathie, identifier et tester ses antécédents et conséquences, en explorant les vécus des médecins et des patients. Par ailleurs, une quatrième étude longitudinale dite pilote a été mise en place. Les résultats ont mis en évidence la spécificité de l'empathie à une clinique spécifique, ont souligné sa nature majoritairement cognitive et comportementale et son rôle primordial dans la clinique et le bien-être des patients et des médecins. Ce travail propose ainsi une définition empirique qui concilie et enrichit les précédentes tout en développant la connaissance des déterminants de cette compétence clinique dans le cas spécifique des maladies chroniques graves. L'empathie clinique résulte de nombreux éléments tant individuels que situationnels ou encore interindividuels. Alors le développement de l'empathie des médecins auprès des personnes atteintes de maladies chroniques graves ne peut être considéré sans développer des recommandations à destination des institutions, des programmes de formation, et des dispositifs de soutien individuel et collectif. / Over the last 15 years, research on clinical empathy in somatic medicine has increased significantly. This clinical empathy is therefore becoming better understood, which shows by the appearance of various models and benefits on patients and physicians. Today, the challenge is to improve and to maintain clinical empathy through medical training and practice while protecting the well-being of physicians. This thesis' aim is to define clinical empathy in the context of serious chronic diseases: its process, its determinants, its consequences and the resources it needs. This work proposes three sequential studies involving patients (N = 15) and hospital doctors (N = 233). The design is mixed between qualitative and quantitative data and methods. These studies seek to define empathy, identify and test its antecedents and its consequences, exploring both the experiences of physicians and patients. Furthermore, a fourth study, a pilot one, has been conducted. Empathy appears as specific to a clinic. The results emphasize its cognitive and behavioral facets. Clinical empathy has a key role in patients' care and wellbeing but also in physicians' wellbeing. This work proposes an empirical definition that reconciles and enriches the preceding ones. It gives the opportunity to develop knowledge of empathy's determinants in the specific case of serious chronic diseases. Clinical empathy is the result of many individual, situational and inter-individual elements. Therefore, the development of doctors' empathy with patients with severe chronic diseases cannot be considered without developing recommendations to institutions, training programs, and individual and collective supports.

Immunoglobulin Therapy and Primary Immunodeficient Patients' Health-Related Quality of Life and Well-Being

Heckman, Niedre 01 January 2018 (has links)
Individuals born with primary immune deficiency diseases (PIDD) have a dysfunctional immune system, and many are treated by lifelong injections of immunoglobulin therapy. Studies have shown that these patients have low health-related quality of life (HRQOL) and well-being (WB) and that these outcomes might be improved by the availability of therapy innovated according to preferences for fewer needle sticks or a shorter infusion time. Regulators at the U.S. Food and Drug Administration (FDA) have approved therapies innovated per these preferences. However, there is limited data demonstrating how these innovations impact HRQOL and WB. Using the biopsychosocial model, the purpose of this cross sectional quantitative study was to evaluate whether patients with PIDD using therapies innovated for fewer needle sticks or a shorter infusion time had a higher mean HRQOL and WB compared to those who were not. The study included 153 patients who completed the Patient Reported Outcomes Measurement Information System (PROMIS)-29 survey. The dependent variables were HRQOL and WB measured by PROMIS-29, and the independent variables were the medical product innovations. Independent samples t tests results showed mean PROMIS-29 scores were not statistically different (p > .05). This suggests patients were optimized according to their treatment preference. A subgroup of patients who had taken the PROMIS-29 survey more than once concurrent with switching to a therapy aligned with patient preferences showed improved HRQOL and WB. These findings have implications for positive social change in that seeking the patient's voice to inform medical product innovation and FDA regulatory decision-making has potential to improve biopsychosocial outcomes.

The role of high mobility group box 1 and toll like receptor 4 in a rodent model of neuropathic pain

Feldman, Polina 20 November 2013 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Neuropathic pain is a serious health problem that greatly impairs quality of life. The International Association for the Study of Pain (IASP) defines neuropathic pain as ‘pain arising as a direct consequence of a lesion or disease affecting the nervous system’. It is important to note that with neuropathy the chronic pain is not a symptom of injury, but rather the pain is itself a disease process. Novel interactions between the nervous system and elements of the immune system may be key facets to a chronic disease state. One of particular note is the recent finding supporting an interaction between an immune response protein high mobility group box 1 (HMGB1) and Toll like receptor 4 (TLR4). HMGB1 is an endogenous ligand for TLR4 that influences the induction of cytokines in many non-neuronal cells. After tissue damage or injury, HMGB1 may function as a neuromodulatory cytokine and influence the production of pro-nociceptive mediators altering the state of sensory neurons. Very little is known about the HMGB1-TLR4 interaction in sensory neurons and whether chronic changes in endogenous HMGB1 signaling influence the establishment of neuropathic pain. This thesis aims to determine whether a physiologically relevant neuroimmune interaction involving endogenous HMGB1 and TLR4 in the dorsal root ganglia is altered following a tibial nerve injury model of neuropathic pain. I hypothesized that sensitization of sensory neurons following a peripheral nerve injury is dependent on endogenous HMGB1 and TLR4. The studies presented here demonstrate that HMGB1 undergoes subcellular redistribution from the nucleus to the cytoplasm in primary afferent neurons following peripheral nerve injury. Further, the presence of extracellular HMGB1 may directly contribute to peripheral sensitization and injury-induced tactile hyperalgesia. Though thought to be important as a pivotal receptor for HMGB1 activation, neuronal protein expression of TLR4 does not appear to influence the effects of HMGB1-dependent behavioral changes following peripheral nerve injury. Taken together, these findings suggest that extracellular HMGB1 may serve as an important endogenous cytokine that contributes to ongoing pain hypersensitivity in a rodent model of neuropathic pain.

La prise en charge des patients souffrant d’une maladie chronique : dynamiques de mise en œuvre d’un modèle de soins

Derraji, Monsef 03 1900 (has links)
Les maladies chroniques regroupent un ensemble de problèmes de santé tels que le diabète, l’hypertension, les maladies pulmonaires obstructives chroniques (MPOC) et le cancer. Elles requièrent une prise en charge continue, durant plusieurs années et évoluent généralement lentement. Ce projet de recherche vise à comprendre et à analyser les dynamiques associées à la mise en place d’un modèle organisationnel qui permet une meilleure prise en charge des patients atteints de maladies chroniques et à porter une attention particulière aux mécanismes professionnels et organisationnels qui favorisent la mise en place de ce modèle de soin dans un contexte pluraliste des organisations et du système de santé. Il vise aussi à explorer si le modèle mis en place permet d’atteindre les objectifs et les résultats de soins escomptés par le modèle. Le contexte de notre étude s’inscrit dans le réseau de l’écosystème des maladies chroniques et des relations inter-organisationnelles lors de l’implantation et de la mise en œuvre du Centre d’accompagnement interdisciplinaire en maladies chroniques CAIMC du CSSS du Haut-Richelieu-Rouville à Saint-Jean-sur-Richelieu. Les données récoltées proviennent d’entrevues individuelles représentatives de l’ensemble des acteurs professionnels du terrain, se fondent sur des documents et rapports, notamment ceux de divers comités de travail ainsi que de protocoles de soins. Notre recherche s’appuie sur le cadre conceptuel de l’analyse stratégique de Crozier et Friedberg (1977) ainsi que sur le système des professions d’Abbott (1988). Elle met en évidence une complexité organisationnelle et structurelle qui rend difficile la gestion du changement dans les organisations pluralistes, surtout lors de l’implantation d’un modèle de soin dans un long horizon temporel. Cette implantation résulte de la gestion d’un processus d’apprentissage continu au sein de l’organisation. Le modèle que nous proposons constitue un cadre d’analyse qui permet une synthèse de diverses approches qui favorisent la compréhension de phénomènes complexes et leur gestion. Il contribue ainsi à raffiner et approfondir la compréhension des dynamiques organisationnelles et professionnelles associées à la mise en place d’un modèle organisationnel. Il peut valablement être utilisé pour l’étude de divers modèles de soins, outre celui des maladies chroniques. Il serait d’ailleurs judicieux de considérer un tel cadre d’analyse avant toute expérimentation ou implantation de modèles de soins dans des organisations pluralistes de santé. Cette étude permet de formuler des recommandations à l’attention des décideurs publics. Elle soutient, notamment, que la mobilisation d’un intrapreneur, ayant l’étoffe d’un leader transformationnel dans un cadre organisationnel agile, favoriserait la création et l’acquisition de connaissances permettant d’accélérer les processus et d’améliorer l’autogestion des patients. / Chronic diseases include a range of health problems such as diabetes, hypertension, chronic obstructive pulmonary disease (COPD) and cancer. They require continuous management over several years and generally evolve slowly. On the one hand, this research project aims to understand and analyze the dynamics associated with the implementation of an organizational model that allows for better management of patients with chronic diseases. On the other hand, it sheds light on the professional and organizational mechanisms that promote this chronic care model's implementation in a pluralistic context of organizations and the health system. Finally, it explores whether the model implemented makes it possible to achieve the model's objectives and results of care. The context of our study is part of the network of the chronic disease ecosystem and inter-organizational relations during the implementation and operation of the Centre d'accompagnement interdisciplinaire en maladies chroniques CAIMC of the CSSS du Haut-Richelieu-Rouville in Saint-Jean-sur-Richelieu. The data collected came from individual interviews representative of all professional actors in the field, documents and reports, particularly those of various working committees and care protocols. Our research is based on the conceptual framework of Crozier and Friedberg's (1977) strategic analysis and Abbott's (1988) system of professions. It highlights an organizational and structural complexity that makes it difficult to manage change in pluralistic organizations, especially when implementing a chronic care model over a long period of time. Implementation results from the management of a continuous learning process within the organization. The model we propose constitutes an analytical framework that allows a synthesis of various approaches that contribute to the understanding of complex phenomena and their management. It thus helps to refine and deepen the understanding of the organizational and professional dynamics associated with the implementation of an organizational model. It could be used for the study of other care models, in addition to chronic diseases. It would be appropriate to consider the use of such an analytical framework before experimentation or implementation of care models in pluralistic health organizations. This study makes several recommendations to public decision-makers. In particular, it argues that the mobilization of an intrapreneur, with the makings of a transformational leader in an agile organizational framework, would promote the creation and acquisition of knowledge to accelerate processes and improve patient self-management.
