Malnutrition prevalence in aged care residents: A pilot study

Malnutrition is a significant clinical and public health problem. The prevalence of malnutrition was determined in a sample of older people living in 2 residential aged care facilities in Australia. The Subjective Global Assessment tool was used to determine the prevalence of malnutrition in 57 residents. The majority of residents were well nourished (67), 26 moderately malnourished, and 7 severely malnourished. Prevalence of malnutrition was higher for those receiving high-level care (42), but this was not statistically significant (P =.437). No relationship was found between malnutrition status and age (P =.529) or sex (P =.839).

Inventing life: Intellectual property and the new biology

In 2009, the National Research Council of the National Academies released a report on A New Biology for the 21st Century. The council preferred the term ‘New Biology’ to capture the convergence and integration of the various disciplines of biology. The National Research Council stressed: ‘The essence of the New Biology, as defined by the committee, is integration—re-integration of the many sub-disciplines of biology, and the integration into biology of physicists, chemists, computer scientists, engineers, and mathematicians to create a research community with the capacity to tackle a broad range of scientific and societal problems.’ They define the ‘New Biology’ as ‘integrating life science research with physical science, engineering, computational science, and mathematics’. The National Research Council reflected: 'Biology is at a point of inflection. Years of research have generated detailed information about the components of the complex systems that characterize life––genes, cells, organisms, ecosystems––and this knowledge has begun to fuse into greater understanding of how all those components work together as systems. Powerful tools are allowing biologists to probe complex systems in ever greater detail, from molecular events in individual cells to global biogeochemical cycles. Integration within biology and increasingly fruitful collaboration with physical, earth, and computational scientists, mathematicians, and engineers are making it possible to predict and control the activities of biological systems in ever greater detail.' The National Research Council contended that the New Biology could address a number of pressing challenges. First, it stressed that the New Biology could ‘generate food plants to adapt and grow sustainably in changing environments’. Second, the New Biology could ‘understand and sustain ecosystem function and biodiversity in the face of rapid change’. Third, the New Biology could ‘expand sustainable alternatives to fossil fuels’. Moreover, it was hoped that the New Biology could lead to a better understanding of individual health: ‘The New Biology can accelerate fundamental understanding of the systems that underlie health and the development of the tools and technologies that will in turn lead to more efficient approaches to developing therapeutics and enabling individualized, predictive medicine.’ Biological research has certainly been changing direction in response to changing societal problems. Over the last decade, increasing awareness of the impacts of climate change and dwindling supplies of fossil fuels can be seen to have generated investment in fields such as biofuels, climate-ready crops and storage of agricultural genetic resources. In considering biotechnology’s role in the twenty-first century, biological future-predictor Carlson’s firm Biodesic states: ‘The problems the world faces today – ecosystem responses to global warming, geriatric care in the developed world or infectious diseases in the developing world, the efficient production of more goods using less energy and fewer raw materials – all depend on understanding and then applying biology as a technology.’ This collection considers the roles of intellectual property law in regulating emerging technologies in the biological sciences. Stephen Hilgartner comments that patent law plays a significant part in social negotiations about the shape of emerging technological systems or artefacts: 'Emerging technology – especially in such hotbeds of change as the life sciences, information technology, biomedicine, and nanotechnology – became a site of contention where competing groups pursued incompatible normative visions. Indeed, as people recognized that questions about the shape of technological systems were nothing less than questions about the future shape of societies, science and technology achieved central significance in contemporary democracies. In this context, states face ongoing difficulties trying to mediate these tensions and establish mechanisms for addressing problems of representation and participation in the sociopolitical process that shapes emerging technology.' The introduction to the collection will provide a thumbnail, comparative overview of recent developments in intellectual property and biotechnology – as a foundation to the collection. Section I of this introduction considers recent developments in United States patent law, policy and practice with respect to biotechnology – in particular, highlighting the Myriad Genetics dispute and the decision of the Supreme Court of the United States in Bilski v. Kappos. Section II considers the cross-currents in Canadian jurisprudence in intellectual property and biotechnology. Section III surveys developments in the European Union – and the interpretation of the European Biotechnology Directive. Section IV focuses upon Australia and New Zealand, and considers the policy responses to the controversy of Genetic Technologies Limited’s patents in respect of non-coding DNA and genomic mapping. Section V outlines the parts of the collection and the contents of the chapters.

Avaliação do perfil de cuidado de enfermagem geriátrico em hospitais de Portugal

A transição demográfica e epidemiológica da população portuguesa tem e terá um enorme impacto na utilização dos recursos de saúde. Atualmente, as pessoas idosas representam um dos grupos etários com taxas de internamento hospitalar mais significativos. Contudo, os dados sobre a hospitalização destas pessoas têm demonstrado resultados de saúde negativos, nomeadamente, o declínio funcional e cognitivo e o risco elevado de eventos adversos. Os/as enfermeiros/as têm um papel crucial na mudança desta realidade. Deste modo, a associação entre o contexto no qual decorre o cuidado de enfermagem geriátrica e os resultados deste cuidado relativos a/os utentes, enfermeiros/as e organizações têm sido proficuamente documentados. Algumas estratégias para promover a qualidade do cuidado geriátrico e a segurança das pessoas idosas hospitalizadas consistem em avaliar e (re)criar o ambiente de trabalho geriátrico dos/as enfermeiros/as (AGTE) e capacitar e treinar estes/as profissionais no cuidado à pessoa idosa. Embora, internacionalmente, os dados demonstrem a associação entre as características de hospitais e/ou enfermeiros/as e o AGTE, não existem estudos em Portugal nesta área, bem como sobre o conhecimento e as atitudes destes profissionais no contexto hospitalar. Por conseguinte, este estudo teve como objetivos: 1) traduzir, adaptar culturalmente e validar as escalas que compõem o questionário Geriatric Institucional Assessment Proflie (GIAP) para a população portuguesa; 2) analisar o AGTE (fatores intrínsecos e extrínsecos) que apoiam ou dificultam a adoção das melhores práticas geriátricas em hospitais portugueses; 3) analisar as atitudes e conhecimento de enfermeiros/as acerca de quatro síndromes geriátricas (úlceras de pressão, distúrbio do sono, contenção física e incontinência), destacando as boas práticas e os problemas encontrados nos hospitais portugueses; 4) analisar a relação entre as variáveis demográficas, profissionais e as características dos hospitais e as escalas que compõem o GIAP – versão portuguesa; 5) conhecer as perceções de enfermeiros/as acerca do cuidado às pessoas idosas hospitalizadas e dos obstáculos enfrentados para desenvolver um cuidado de boa qualidade; e 6) analisar a relação entre a perceção de enfermeiros/as sobre o AGTE e o conhecimento e atitudes geriátricas destes profissionais em função da região e unidade de internamento. Este estudo foi desenvolvido com base num método quantitativo do tipo exploratório-descritivo, transversal, prospetivo e correlacional. A amostra foi constituída por 1.068 enfermeiros/as de cinco hospitais da região norte e centro do país. A recolha de dados foi desenvolvida através de autopreenchimento do GIAP – versão portuguesa. De entre os principais resultados destacam-se: 1) a obtenção de um instrumento válido e fiável para avaliar o AGTE e conhecimentos e atitudes geriátricas; 2) a perceção de enfermeiros/as sobre o cuidado às pessoas idosas como sendo predominantemente negativa; 3) a perceção de enfermeiros/as sobre o apoio insuficiente dos líderes hospitalares para promover um AGTE favorável; 4) o cuidado a pessoas idosas com comportamentos inadequados e o uso de recursos geriátricos como os principais fatores que influenciam a eficácia e a qualidade do cuidado geriátrico; 5) a lacuna de conhecimento e atitudes negativas de enfermeiros/as acerca das quatro síndromes geriátricas; 6) a conceptualização de um modelo sobre a associação das características de enfermeiros/as, dos hospitais do estudo e das perceções destes/as profissionais sobre o cuidado geriátrico com o AGTE e o conhecimento e atitudes geriátricos; 7) a falta de apoio familiar, a descontinuidade e a escassez de tempo para o cuidado como principais obstáculos no cuidado à pessoa idosa hospitalizada; e 8) o perfil de cuidado geriátrico nos hospitais da região norte e centro de Portugal como tendencialmente homogéneo. Os resultados deste estudo sustentam a necessidade de um maior investimento dos decisores políticos, administradores hospitalares e docentes de Enfermagem na capacitação dos/as enfermeiros/as para o cuidado geriátrico e na promoção de um AGTE mais favorável. Também oferece recomendações significativas nos domínios da decisão política, da gestão institucional e da prática profissional que devem ser alvo de uma discussão alargada entre os vários agentes com responsabilidade nestes domínios. Espera-se que este estudo possa contribuir para a promoção de um contexto favorável ao desenvolvimento de um cuidado de enfermagem geriátrica de boa qualidade às pessoas hospitalizadas.

Äldre och ensamhet : En kartläggning av sociala insatser för äldre personer i Dalarnas kommuner

Det finns begränsat med forskning kring hur biståndshandläggare inom äldreomsorgen arbetar med ensamhet hos äldre personer. Med anledning av detta är studiens huvudsakliga syfte att undersöka hur biståndshandläggare i Dalarnas kommuner arbetar med att utreda sociala behov till följd av ensamhet hos äldre personer samt att ta reda på vilka kommunala sociala insatser som erbjuds för dessa individer och på vilka grunder. Studien är genomförd utifrån en kvantitativ ansats, där vi har använt oss av en enkät, som innehåller frågor som avser att besvara syftet. Tolkningsramen för analysen av det empiriska materialet utgörs av Lipskys teori om gräsrotsbyråkrati. Studiens resultat visar att det finns behov av att både utöka och utveckla kommunernas utbud av sociala insatser för äldre personer samt att utveckla rutiner för hur man ska arbeta med ensamhet hos äldre personer. Studien påvisar ett behov av mer forskning, både internationell och nationell, kring hur biståndshandläggare arbetar med att identifiera ensamhet hos äldre personer.

Riskfaktorer och förebyggande omvårdnadsåtgärder för UVI hos äldre kvinnor : En litteraturöversikt

Bakgrund: Urinvägsinfektion (UVI) är en av de vanligaste infektionerna hos äldre kvinnor. Escherichia coli (E-coli) är den vanligaste bakterien vid UVI. Äldre kvinnor lider när de är drabbade av UVI och det är sjuksköterskans uppgift att bland annat förebygga sjukdom och lindra lidande. Syfte: Att beskriva riskfaktorer och förebyggande omvårdnadsåtgärder mot UVI hos äldre kvinnor. Metod: Litteraturstudie, med databassökning genom databaser speciellt inriktade på vård och omvårdnad, CINAHL, PubMed, WEB OF SCIENCE och Medline. 15 artiklar har använts till resultatet. Resultat: Recidiverande UVI, diabetes, urininkontinens, smittspridning och förstoppning är riskfaktorer att drabbas av UVI. God hygien och regelbunden tillförsel av vätska ses som god evidensbaserad omvårdnadsåtgärd mot UVI. Ökad tillförsel av vätska förkastas, Tranbärstillägg behöver ytterligare forskning. Slutsats. Hög hygieniskstandard genom de basala hygienrutinerna är en viktig förebyggande åtgärd mot UVI.

Developing a quick and practical screen to improve the identification of poor hydration in geriatric and rehabilitative care

Dehydration has been associated with increased morbidity and mortality. Dehydration risk increases with advancing age, and will progressively become an issue as the aging population increases. Worldwide, those aged 60 years and over are the fastest growing segment of the population. The study aimed to develop a clinically practical means to identify dehydration amongst older people in the clinical care setting. Older people aged 60 years or over admitted to the Geriatric and Rehabilitation Unit (GARU) of two tertiary teaching hospitals were eligible for participation in the study. Ninety potential screening questions and 38 clinical parameters were initially tested on a single sample (n=33) with the most promising 11 parameters selected to undergo further testing in an independent group (n=86). Of the almost 130 variables explored, tongue dryness was most strongly associated with poor hydration status, demonstrating 64% sensitivity and 62% specificity within the study participants. The result was not confounded by age, gender or body mass index. With minimal training, inter-rater repeatability was over 90%. This study identified tongue dryness as a potentially practical tool to identify dehydration risk amongst older people in the clinical care setting. Further studies to validate the potential screen in larger and varied populations of older people are required

A prospective cohort study of geriatric syndromes among older medical patients admitted to acute care hospitals

OBJECTIVES: To identify the prevalence of geriatric syndromes in the premorbid for all syndromes except falls (preadmission), admission, and discharge assessment periods and the incidence of new and significant worsening of existing syndromes at admission and discharge. DESIGN: Prospective cohort study. SETTING: Three acute care hospitals in Brisbane, Australia. PARTICIPANTS: Five hundred seventy-seven general medical patients aged 70 and older admitted to the hospital. MEASUREMENTS: Prevalence of syndromes in the premorbid (or preadmission for falls), admission, and discharge periods; incidence of new syndromes at admission and discharge; and significant worsening of existing syndromes at admission and discharge. RESULTS: The most frequently reported premorbid syndromes were bladder incontinence (44%), impairment in any activity of daily living (ADL) (42%). A high proportion (42%) experienced at least one fall in the 90 days before admission. Two-thirds of the participants experienced between one and five syndromes (cognitive impairment, dependence in any ADL item, bladder and bowel incontinence, pressure ulcer) before, at admission, and at discharge. A majority experienced one or two syndromes during the premorbid (49.4%), admission (57.0%), or discharge (49.0%) assessment period.The syndromes with a higher incidence of significant worsening at discharge (out of the proportion with the syndrome present premorbidly) were ADL limitation (33%), cognitive impairment (9%), and bladder incontinence (8%). Of the syndromes examined at discharge, a higher proportion of patients experienced the following new syndromes at discharge (absent premorbidly): ADL limitation (22%); and bladder incontinence (13%). CONCLUSION: Geriatric syndromes were highly prevalent. Many patients did not return to their premorbid function and acquired new syndromes.

'Online' geriatric assessment procedure for older adults referred for geriatric assessment during an acute care episode for consideration of reliability of triage decisions

Background Comprehensive geriatric assessment has been shown to improve patient outcomes, but the geriatricians who deliver it are in short-supply. A web-based method of comprehensive geriatric assessment has been developed with the potential to improve access to specialist geriatric expertise. The current study aims to test the reliability and safety of comprehensive geriatric assessment performed “online” in making geriatric triage decisions. It will also explore the accuracy of the procedure in identifying common geriatric syndromes, and its cost relative to conventional “live” consultations. Methods/Design The study population will consist of 270 acutely hospitalized patients referred for geriatric consultation at three sites. Paired assessments (live and online) will be conducted by independent, blinded geriatricians and the level of agreement examined. This will be compared with the level of agreement between two independent, blinded geriatricians each consulting with the patient in person (i.e. “live”). Agreement between the triage decision from live-live assessments and between the triage decision from live-online assessments will be calculated using kappa statistics. Agreement between the online and live detection of common geriatric syndromes will also be assessed using kappa statistics. Resource use data will be collected for online and live-live assessments to allow comparison between the two procedures. Discussion If the online approach is found to be less precise than live assessment, further analysis will seek to identify patient subgroups where disagreement is more likely. This may enable a protocol to be developed that avoids unsafe clinical decisions at a distance. Trial registration Trial registration number: ACTRN12611000936921

Models of care in geriatric oncology nursing

Using the hidden Markov model to capture quality of care in Lombardy geriatric wards

Quality of care is an important aspect of healthcare monitoring, which is used to ensure that the healthcare system is delivering care of the highest standard. With populations growing older there is an increased urgency in making sure that the healthcare delivered is of the highest standard. Healthcare providers are under increased pressure to ensure that this is the case with public and government demand expecting a healthcare system of the highest quality. Modelling quality of care is difficult to measure due to the many ways of defining it. This paper introduces a potential model which could be used to take quality of care into account when modelling length of stay. The Coxian phase-type distribution is used to model length of stay and the associated quality of care incorporated into the Coxian using a Hidden Markov model. Covariates are also introduced to determine their impact on the hidden level to find out what potentially can affect quality of care. This model is applied to geriatic patient data from the Lombardy region of Italy. The results obtained highlighted that bed numbers and the type of hospital (public or private) can have an effect on the quality of care delivered.
