Syftet med litteraturstudien var att beskriva vilka faktorer som i omvårdnadsforskningen beskrivs som bidragande faktorer till akut delirium. Syftet var vidare att beskriva vilka omvårdnadsåtgärder som omvårdnadsforskningen tar upp som kan minska risken för uppkomst av akut delirium. Resultatet baserades på vetenskapliga artiklar som söktes i följande databaser: Elin@dalarna, BlackwellSynergy, PubMed och EBSCO host. Följande sökord användes: delirium, acute, elderly, nursing, patients, caring, management, confusional state, needs. Artiklarna granskades enligt en granskningsmall med avseende på vetenskaplig kvalité. Betydande riskfaktorer för akut delirium var ålder, flera samtidiga sjukdomar, antalet mediciner och typ av medicin. Förutom att genomgå operation var också många åtgärder, framför allt invasiva åtgärder, tidigt under sjukhusvistelsen riskfaktorer för akut delirium. Även flera rumsbyten var en riskfaktor. Viktiga åtgärder för att förebygga akut delirium var psykiatrisk konsultation, tekniker för att underlätta orientering, emotionellt stöd, patientundervisning och anhörigundervisning, patientorientering, fysisk kontakt med patient samt att upprätta kontakt med kurator.

Acute confusional state (ACS) or delirium according to DSM-III-R holds a central position in the medicine of old age. ACS is a common and sometimes the only symptom of diseases and medical complications in the elderly patient. The aim of this study was to elucidate ACS in patients with femoral neck fractures and patients with acute stroke with regard to frequency, predictors, possible pathogenetic mechanisms, associated complications, assessment and documentary routines and the clinical outcome for the patients. An intervention program to prevent postoperative ACS based on our results was developed and evaluated. The main findings of the study were high frequencies of ACS in elderly patients with femoral neck fractures (61 %) and in patients with acute stroke (48 %). The main risk factors for ACS in patients with femoral neck fractures were old age, diseases and drug treatment interfering with cerebral cholinergic metabolism. There was no link between anaesthetic technique and ACS but the connection between peroperative hypotension, early postoperative hypoxia and ACS was close. In stroke patients the degree of extremity paresis and old age were independent ACS risk factors. ACS was commonly associated with post stroke complications such as myocardial infarction, pneumonia, urinary infection and urinary retention. In stroke patients there was a close connection between high hypothalamic-pituitary-adrenal axis (HPA-axis) activity and ACS. High HPA-axis activity and disturbances in the cerebral cholinergic system may be two important ACS mechanisms. A correct diagnosis is a prerequisite for proper treatment of ACS and its underlying causes. In the orthopaedic wards both physicians and nurses diagnosed and documented ACS poorly and therefore associated complications were insufficiently treated. The intervention program for postoperative ACS, aimed mainly at protecting the cerebral oxidative metabolism and thereby the cerebral cholinergic metabolism which is especially sensitive to hypoxia. Postoperative complications associated with ACS were also treated. The intervention resulted in reduced frequency, duration and severity of postoperative ACS and in shorter orthopedic ward stay for patients with femoral neck fractures.Key words: Acute confusional state, delirium, elderly / <p>S. 1-76: sammanfattning, s. 77-175: 6 uppsatser</p> / digitalisering@umu

Delirium is a severe neuropsychiatric syndrome, characterised by the acute onset of inattention, altered level of arousal, and other mental status abnormalities. Delirium is extremely common in acute stroke, affecting at least 1 in 5 such patients admitted to hospital. It is a serious complication of stroke, being associated with higher mortality, longer length of hospital stay and higher dependency at discharge. The pathophysiology of delirium is not completely understood, and there are no specific treatments. This thesis investigated the role of cortisol in the development of delirium after stroke and also investigated the role of delirium and of cortisol in the development of cognitive impairment in the 12 months after stroke. The thesis specifically investigated whether levels of cortisol in saliva are elevated in delirium and also whether there is a loss of the normal diurnal rhythm in delirium, evidenced by elevated afternoon salivary cortisol levels and reduced morning level to afternoon level ratio. The thesis also investigated whether cortisol levels are persistently elevated in the year after stroke in those who developed delirium and whether cortisol levels are associated with cognitive decline. Finally it investigated whether acute and/or chronic changes seen on Computed Tomography (CT) brain scans taken around the time of stroke onset are associated with the development of delirium after stroke A longitudinal cohort study was conducted in 95 participants aged 60 years or over, who were admitted to hospital with a clinically confirmed stroke. Participants gave informed consent, or proxy consent was obtained if they lacked capacity to consent. At baseline participants underwent brief cognitive testing and were then assessed for the presence of delirium, using DSM IV criteria, at regular intervals during the first two weeks after stroke. At each assessment a saliva sample was collected in the morning and in the afternoon, to measure cortisol. Participants were then visited at 1 month, 4 months and 12 months after stroke onset, at which point they were assessed for the presence of delirium, further saliva samples were taken and a cognitive test battery was completed. 26 (27%) participants developed delirium during the course of the study period. The study found elevated salivary cortisol levels in those with delirium at up to 4 months after stroke, but at 12 months there was no difference between the delirium and no delirium group. A loss of the diurnal rhythm was seen in those who developed delirium at 5 days after stroke, but the diurnal variation had returned to a normal pattern at follow-up. However, in a multivariate analysis, controlling for age, sex, stroke severity (NIHSS), current illness burden (APACHE II), chronic illness burden (CCI) and prior cognitive impairment (IQCODE), neither median salivary cortisol levels in the first two weeks after stroke, nor the ratio of morning to afternoon cortisol levels were independent predictors of delirium diagnosis, although median 9am cortisol approached significance (OR=0.95, 95% confidence interval (CI) 0.89-1.01, p=0.08). In a random effects logistic regression analysis, the probability of developing delirium decreased over time from stroke onset and increased per unit increase in salivary cortisol (nmol/L), however this effect was not statistically significant (OR 1.02, CI 0.84-1.19 P=0.70 for morning cortisol and OR 1.05, CI 0.82-1.25 p=0.46 for afternoon cortisol). Global cognition, measured by the MoCA, was significantly poorer in the delirium group at each time point throughout the 12 months after stroke. However, there was a trend towards improvement in MoCA scores in the whole cohort throughout the 12 month follow-up, with the exception of those who developed the most severe delirium. The presence of delirium at any point during the 12 month follow-up did not affect the rate of change of the MoCA scores over the 12 months after stroke. The presence of brain atrophy identified on admission CT brain scans was independently associated with delirium (OR 3.7, CI 1.15-11.88, p=0.02), however the presence of a visible acute or chronic stroke lesion and the presence of white matter lesions were not. Finally, those who developed delirium had a worse functional outcome, longer length of hospital stay and were more likely to require institutional care or a package of care at home, compared with those who did not develop delirium. This thesis has contributed to our understanding of the mechanisms and phenomenology of delirium after stroke, and has also highlighted areas for further research which will be required to unpick the complex pathophysiology of delirium.

<p>Delirium is common among old patients admitted to hospital, but is often a neglected problem in patient care. The principal aim of this thesis was to evaluate aspects of delirium in relation to incidence, risk factors, behavioural changes, cognitive function and health-related quality of life (HRQOL). A further aim was to describe patients’ experiences of being delirious. The study was prospective, descriptive and comparative, with repeated measures (six-month follow up). The sample consisted of 225 consecutive patients, aged 65 years or older, who were to be operated on due to hip fracture or hip replacement. Exclusion criteria were serious cognitive disorder or delirium on admission. Data were collected via frequent daily observations, cognitive functioning tests (MMSE), HRQOL questionnaires (SF-36) and interviews. Delirium was assessed according to the DSM-IV criteria. A total of 45/225 became delirious, with an incidence of 24.3% among patients undergoing hip fracture surgery and 11.7% among those with hip replacement surgery. A predictive model for delirium included four factors: impaired hearing, passivity, low cognitive functioning, and waiting more than 18h for hip fracture surgery. Disorientation and urgent calls for attention were the most frequent behavioural changes in the prodromal phase prior to delirium. Delirium in connection with hip fracture revealed deteriorated HRQOL and cognitive functioning when measured at a six-month follow-up. The experience of being delirious was described by the patients as a sudden change of reality. Such an experience gave rise to strong emotional feelings, as did recovery from delirium. Nurses’ observations of behavioural changes in old patients with impaired cognitive function may be the first step in managing and reducing delirium. The predictive model of delirium ought to be tested further before use in clinical practice.</p>

Les personnes âgées occupent une proportion importante des lits dans les centres hospitaliers de soins de courte durée québécois et leur présence est en augmentation. Parmi ces personnes, plusieurs présentent un état confusionnel aigu (ÉCA), voire un délirium, au cours de leur hospitalisation. Les soins infirmiers qu’elles requièrent sont complexes et les études portant sur la formation continue des infirmières tiennent peu compte de cette réalité. Les approches utilisées dans les études sont surtout centrées sur l’acquisition de connaissances et d’habiletés techniques et négligent les aspects créatifs, relationnels, critiques, réflexifs et éthiques essentiels à une prestation de soins infirmiers de qualité. On y retrouve également peu d’informations sur la conception de l’intervention éducative et sur son évaluation. C’est dans cette perspective que le but de l’étude était de mettre à l’essai et d’évaluer qualitativement le processus et les résultats d’une intervention éducative auprès d’infirmières soignant des personnes âgées hospitalisées en ÉCA. Plus particulièrement, ce sont les conditions facilitant et contraignant l’intervention, les aspects les plus utiles pour la pratique, les différents savoirs exprimés et les résultats de soins perçus par les participantes qui étaient recherchés. C’est en s’inspirant de la pédagogie narrative de Diekelmann (2001) et des savoirs infirmiers de Chinn et Kramer (2008) que l’intervention a été conçue et évaluée. La description d’expériences de soins vécues par les infirmières et la création d’un environnement d’apprentissage favorisant l’interprétation, en groupe, de ces expériences à l’aide d’informations théoriques et empiriques caractérisent la pédagogie narrative à la base de cette intervention. Pour atteindre le but, une étude de cas a été retenue. La stratégie d’échantillonnage par choix raisonné a permis de sélectionner des participantes travaillant sur les trois quarts de travail, ayant différents niveaux de formation et une expérience comme infirmière variant de huit mois à 36 ans, dont l’âge variait de 23 à 64 ans. L’échantillon, composé de 15 infirmières soignant fréquemment des personnes en ÉCA et travaillant sur des unités de soins chirurgicaux cardiologiques et orthopédiques, était réparti dans trois groupes égaux de cinq participantes. L’intervention éducative comprenait quatre journées de formation offertes à intervalle de trois semaines pour une durée totale de 12 semaines. Au cours de chacune de ces journées, les participantes devaient effectuer un travail écrit réflexif concernant une situation de soins vécue avec une personne en ÉCA et, par la suite, partager, interpréter et s'interroger sur ces situations en faisant des liens avec des informations théoriques et empiriques sur l’ÉCA dans le cadre d’un atelier de groupe. Une triangulation de méthodes de collecte de données, incluant des notes de terrain de l’investigatrice, les travaux réflexifs des participantes, des questionnaires complétés par les participantes après chaque journée de formation et une entrevue individuelle avec chaque participante réalisée par une intervieweuse externe à la fin de l’intervention, a permis de décrire la mise à l’essai de l’intervention et d’évaluer qualitativement son processus et ses résultats. Une analyse de contenu des données qualitatives intra et inter participante a été effectuée. La mise à l’essai de l’intervention a mis en évidence l’importance de tenir compte des besoins variés des participantes et d’ajuster l’intervention éducative d’un groupe à l’autre, notamment eu égard aux contenus théoriques et empiriques sur l’ECA. L’évaluation du processus souligne que l’intervention a été facilitée par les attitudes et la diversité des expériences des participantes, ainsi que par l’utilisation de situations de soins réelles permettant d’intégrer la théorie dans la pratique. L’accès à de nouveaux outils d’évaluation des personnes en ÉCA a été perçu particulièrement utile par les participantes. Quant à l’évaluation des résultats, elle a permis de rendre visibles de nombreux savoirs empiriques, éthiques et esthétiques et certains savoirs personnels et émancipatoires exprimés par les participantes. Les participantes ont, entre autres, réalisé des évaluations plus approfondies des personnes en ÉCA, ont réduit ou évité les mesures de contrôle physiques des personnes atteintes et ont impliqué davantage les familles dans les soins. L’évaluation a aussi permis de décrire certains résultats perçus par les participantes sur le bien-être physique et psychologique des personnes soignées et sur les familles. Les personnes en ECA étaient, entre autres, rassurées, plus calmes et soulagées et les familles moins inquiètes et davantage impliquées dans les soins. Les résultats de l’étude mettent en évidence l’applicabilité d’une intervention éducative narrative basée sur un cadre de référence en sciences infirmières et son utilité pour la formation continue dans les milieux de soins. L’étude ouvre la porte à des possibilités de transfert de l’intervention à d’autres populations d’infirmières soignant des clientèles ayant des besoins complexes, notamment en gériatrie, en oncologie ou en soins palliatifs. Des études visant à évaluer l’intervention auprès d’un échantillon plus important et à explorer ses effets sur les personnes soignées et leurs familles sont proposées. / Older persons occupy a growing proportion of the beds in Quebec short-stay hospitals. Many of these persons present acute confusional state (ACS), or delirium, in the course of their hospitalization. The nursing care that they require is complex but studies show that continuing nursing education takes scant account of this reality. The approaches used in these studies have focused above all on the acquisition of knowledge and technical skills and have neglected the creative, relational, critical, reflexive and ethical aspects essential to delivering quality nursing care. In addition, these studies contain little information relative to the design of pedagogical interventions and their evaluation. Against this background, a study was undertaken aimed at field-testing and qualitatively evaluating the process and results of a pedagogical intervention for nurses who care for hospitalized older persons with ACS. The focus was more specifically on identifying the facilitating and constraining conditions to learning, the aspects most useful to practice, the different types of knowledge expressed, and the care outcomes perceived by participants. Inspiration for the design and evaluation of the intervention was drawn from the narrative pedagogy approach developed by Diekelmann (2001) and the various patterns of knowing knowledge defined by Chinn and Kramer (2008). The narrative pedagogy at the root of this intervention consists essentially of describing the lived care experiences of nurses and creating a learning environment conducive to group interpretation of these experiences based on theoretical and empirical data. To achieve the objectives, a case study design was used. Purposive sampling allowed selecting participants working all three work shifts, possessing different levels of training, boasting nursing experience ranging from eight months to 36 years, varying in age from 23 to 64 years. The sample, composed of 15 nurses who worked on cardiac and orthopedic surgery units and who often cared for persons with ACS, was divided into three equal groups of five. The pedagogical intervention comprised four days of training offered at an interval of three weeks for a total duration of 12 weeks. On each of these days, participants had to complete a written reflexive exercise regarding a lived care situation involving a person with ACS and then, in the context of a group discussion, share, interpret and question these situations by drawing connections with available theoretical and empirical data on ACS. A triangulation of data collection methods, including the investigator’s field notes, the participants’ written reflexive exercises, questionnaires completed by the participants after each day of training, and individual interview with each participant carried out by an outside interviewer at the end of the intervention, allowed describing the field-testing of the intervention and qualitatively evaluating its process and results. The qualitative intra and inter-participant data was then subjected to content analysis. Field-testing of the intervention highlighted the importance of taking account of the varied needs of the participants and to adjust the pedagogical intervention from one group to the next, particularly with respect to the theoretical and empirical content on ACS. Process evaluation underscored that the intervention was facilitated by the attitudes and the diversity of experiences of the participants, as well as by the use of real care situations, which allowed integrating theory in practice. Access to new tools for assessing persons with ACS was perceived to be particularly useful by the participants. As for the results evaluation, it allowed revealing various types of knowledge, including of the empirical, ethical and esthetic sort, but also some personal and emancipatory knowledge expressed by the participants. Moreover, the participants performed more in-depth assessments of persons with ACS, reduced or avoided the use of physical control measures on these persons, and involved families more in care. The evaluation also allowed documenting some of the effects perceived by the participants on the physical and psychological well-being of care recipients and their families. Persons with ACS were reassured, calmer and soothed, among other things, while families were less worried and more involved in care. The study’s results evidence the applicability of a narrative pedagogy intervention based on a nursing frame of reference and its utility in continuing education in the field of care. The study opens up the possibility of transferring the intervention to other populations of nurses who tend to clienteles with complex needs, particularly in geriatric, oncological and palliative care. It is proposed that future studies evaluate the intervention on a larger sample and explore its effects on the persons cared for and their families.
