RESUMO

BACKGROUND: Healthcare-associated infections (HAIs) burden healthcare globally. Amid the SARS-CoV-2 pandemic, intensified infection control measures, such as mask usage and hand hygiene, were implemented. AIM: To assess the efficacy of these measures in preventing HAIs among hospitalized patients. METHODS: Using the PICO framework (Population, Intervention, Comparison, Outcome), the study focused on hospitalized patients and the effectiveness of anti-COVID-19 measures in preventing HAIs. A systematic review of literature published in 2020-2022 was conducted, examining interventions such as mask usage, hand hygiene, and environmental cleaning. FINDINGS: This systematic review analysed 42 studies: two in 2020, 21 in 2021, and 19 in 2022. Most studies were from high-income countries (28). Most studies (30 out of 42) reported a reduction in HAIs after implementing anti-COVID-19 measures. Gastrointestinal infections and respiratory tract infections showed significant reduction, unlike bloodstream infections and urinary tract infections. Some wards, like cardiology and neurology, experienced reduced HAIs, unlike intensive care units and coronary care units. There was an increase in studies reporting no effect of hygiene measures on HAIs in 2022, eventually indicating a shift in effectiveness over time. CONCLUSION: Anti-COVID-19 measures have shown selective efficacy in preventing HAIs. The study emphasizes the need for context-specific strategies and increased focus on regions with limited resources. Continued research is essential to refine infection control practices, especially in high-risk settings.

RESUMO

Background: The population of the European Union is progressively ageing, therefore frailty is becoming a crucial public health issue. In recent years there is a growing interest in a multidimensional concept of frailty, that is not only physical but also psychological and social, in line with a person-centered care. Study design: To measure frailty represents a fundamental step to evaluate the needs for care at both population and individual levels. Of course, to assess frailty in a large population is essential to find short and quick tools able to give reliable results in terms of risk of occurrence of negative events, to stratify older adults according to their frailty level. In this way the most appropriate strategies can be chosen and applied, to delay the functional decline associated to frailty and its consequences, such as hospitalization, institutionalization, low quality of life, and death. Methods: In this review we searched on PubMed for articles about scales assessing frailty with peculiar characteristics: published for the first time in 2010, available in English, with a short length and duration of administration, composed by multidimensional domains. Results: Seven scales were found and analyzed: The Zulfiqar Frailty Scale (ZFS), The Pictorial Fit-Frail Scale (PFFS), The Tilburg Frailty Indicator (TFI), The SUNFRAIL Tool, The (fr)AGILE, The Risk Instrument for Screening in the Community (RISC) and The Short Functional Geriatric Evaluation (SFGE). We compared their main features as the number of questions, the time for administration, the domains used and the psychometric properties as validity and reliability, with the aim of providing a set of useful information to health professionals in their everyday work. Conclusions: The use of these tools provides important information to help plan community health and social care and meet individuals' needs for care, but this approach is not common for community care in the EU yet.

RESUMO

Abstract: We appreciate that Dr. Zulfiqar showed us that they had already demonstrated the validity and reliability of his ZFS scale. Still, it is evident that, in our paper, we could not take it for granted because all the articles they quote have been published after we handed out ours to the Managing Editor of Ann Ig.

RESUMO

Background: Demographic changes have forced communities and people themselves to reshape ageing concepts and approaches and try to develop actions towards active and healthy ageing. In this context, the European Commission launched different private-public partnerships to develop new solutions and answers on questions related to this topic. The European Innovation Partnership on Active and Healthy Ageing, including topic related action groups as well reference sites committed towards a common action to facilitate active and healthy ageing, has contributed key elements for interventions, scaled up best practices and evaluated impact of their action to drive innovation across many regions in Europe over the past years. Methods: This paper describes action taken by A3 action group in the European Innovation Partnership on Active and Healthy Ageing. This paper gives an overview of how the partnership combined the view on frailty coming from public health as well as the clinical management. Results: Within different European regions, to tackle frailty, EIPonAHA partners have conceptualized functional decline and frailty, making use of good practice models working well on community programs. The A3 Group of EIPonAHA has worked alongside a process of innovation, targeting all ageing citizens with the clear goal of involving communities in the preventive approach. Conclusion: Engagement needs of older people with a focus on functionally rather than disease management as primary objective is considered as an overarching concept, also embracing adherence, compliance, empowerment, health literacy, shared decision-making, and activation. Furthermore, training of staff working with ageing people across all sectors needs to be implemented and evaluated in future studies.

RESUMO

Background: Bio-psycho-social frailty can negatively affect the health status of an ageing population. The integration between community nurses and social services can emphasize community care and prevent the onset of both health and social negative outcomes in the older population. The aim of the paper is to explore the causal association through the analysis of the hospitalization and mortality rate after a pro-active social service integrated by the community nurse. Study Design: A nested case-control study comparing groups of older adults has been carried out. Methods. The paper compares data stem from a cohort followed up by the University of Rome "Tor Vergata" with data from the "Long Live the Elderly!" program (LLE) cohort. Results: One-year standardized mortality rate was 6.5%, 4.7% and 7.5% in the control group, the LLE group and the LLE group integrated by the community nurse (LLE-CN), respectively. One-year hospitalization rate was 15.4%, 15.5% and 10.8% in the control group, the LLE group and the LLE-CN group, respectively. Conclusions: According to our results a social service with a pro-active approach, integrated by the community nurse, appears to be able to reduce mortality and hospitalization in a group of older adults aged>75. The multidimensional assessment of frailty stands for the first step of a new organization of community services.

RESUMO

The meeting of the European Innovation Partnership on Active and Healthy Ageing (EIPonAHA) action group A3 together with members of the Reference site collaborative network (RSCN) in December 2019 in Rome focused on integration of evidence-based approaches on health and care delivery for older citizens at different levels of needs with expertise coming from stakeholder across Europe. It was the final aim of the group to co-create culturally sensitive pathways and facilitate co-ownership for further implementation of the pathways in different care systems across Europe. The study design is a mixed method approach. Based on data analysis from a cohort of community-dwelling over-65 citizens in the framework of a longitudinal observational study in Rome, which included health, social and functional capacity data, three personas profiles were developed: the pre-frail, the frail and the very frail personas. Based on these data, experts were asked to co-create care pathways due to evidence and eminence during a workshop and included into a final report. All working groups agreed on a common understanding that integration of care means person-centered integration of health and social care, longitudinally provided across primary and secondary health care including citizens' individual social, economic and human resources. Elements for consideration during care for pre-frail people are loneliness and social isolation, which, lead to limitation of physical autonomy in the light of reduced access to social support. Frail people need adaption of environmental structures and, again, social resource allocation to maintain at home. Very frail are generally vulnerable patients with complex needs. Most of them remain at home because of a strong individual social support and integrated health care delivery. The approach described in this publication may represent a first approach to scaling-up care delivery in a person-centered approach.

RESUMO

The aim of this paper is to describe the protocol of a study assessing the impact of a Community-based pro-Active Monitoring Program, by measuring the effect in counteracting the adverse outcomes related to frailty. METHODS: a prospective pragmatic trial will be carried out to describe the impact of an intervention on people aged>80, adjusted for relevant parameters: demographic variables, comorbidities, disability and bio-psycho-social frailty. They have been assessed with the Functional Geriatric Evaluation questionnaire that is a validated tool. Mortality, Acute Hospital Admission rates, Emergency Room Visit rates and Institutionalization rates are the main outcomes to be evaluated annually, over three years. Two groups of patients, made up by 578 cases (undergoing the intervention under study) and 607 controls have been enrolled and interviewed. RESULTS: at baseline the two groups are quite similar for age, living arrangement, comorbidity, disability and cognitive status. They differ in education, economic resources and physical status (that are better in the control group) and in social resources (that is better in the case group). The latter was expected since the intervention is focused on increasing social capital at individual and community level and aimed at improving survival among the cases as well as reducing the recourse to hospital and residential Long Term Care. CONCLUSION: The proposed study addresses a crucial issue: assessing the impact of a bottom up care service consisting of social and health interventions aimed at reducing social isolation and improving access to health care services.

RESUMO

We developed and tested an innovative physical training method in older adults that embeds the gym program into everyday life in the most conservative way possible. Physical training was included in the activities of local parishes where older women from Southern Italy spend most of their free time and was delivered by trained physical therapists with the support of an ICT tool known as CoCo. 113 older women (aged 72.0 [69.0-75.0] years) noncompliant to conventional exercise programs participated to the study. 57 of them underwent the final anthropometric assessment and 50 the final physical tests. In study completers handgrip strength and physical performance evaluated with the chair-stand, the two minutes step and the chair-sit and -reach tests significantly improved. Quality of life as evaluated with the EuroQol-5dimension (EQ-5D) questionnaire improved as well. In conclusion, a training program designed to minimally impact on life habits of older people is effective in improving fitness in patients noncompliant to other to physical exercise programs.

RESUMO

INTRODUCTION: The paper describes the impact on Hospital Admissions of a program targeting the community-dwelling older citizens with social interventions aimed at managing frailty and reducing social isolation. STUDY DESIGN: The study is quasi-experimental intervention program. METHODS: A randomized sample made up by 207 participants (cases) to the Long Live the Elderly program is compared with a cohort of 308 older adults (controls) followed up since 2014 by the University of Tor Vergata. At the enrolment all the participants have been administered a multidimensional questionnaire to assess frailty. After six months, the two groups are compared for the inpatient's admission rate. RESULTS: The percentage of patients who was admitted to the hospital during the first six month of follow up was 9.1% and 8.3% among the controls and the cases respectively. The inpatient's admission rate was higher among the controls (251.6 per 1000 observation/year) than for the cases (167.3). Despite the cases were older than the controls (mean age 83.5, SD±8.1 vs 76.7, SD±7.1; p=0.001), showed a lower percentage of frail/very frail individuals (29.5% vs 33.4%). The multivariate linear regression adjusted for gender, age and frailty showed a reduction of the hospital admission rate associated to the Long Live the Elderly program (p=0.013). CONCLUSIONS: The study suggests the impact on the reduction of acute hospital admission in the first six months of follow up, of a Community-based Program aimed at increasing the social capital of older adults. Further studies with longer follow up are needed to confirm the study results in order to support the hypothesis that the future sustainability of health systems is partially linked to the increase of the social component of community care service.

RESUMO

INTRODUCTION: Frailty screening and assessment are a fundamental issue in Public Health in order to plan prevention programs and services. METHODOLOGY: By a narrative review of the literature employing the International Narrative Systematic Assessment tool, the authors aims to develop an updated framework for the main procedures and measurement tools to assess frailty in older adults, paying attention to the use in the primary care setting. RESULTS: The study selected 10 reviews published between January 2010 and December 2016 that define some characteristics of the main tools used to measure the frailty. Within the selected reviews only one of the described tools met all the criteria (multidimensionality, quick and easy administration, accurate risk prediction of negative outcomes and high sensitivity and specificity) necessary for a screening tool. CONCLUSION: Accurate risk prediction of negative outcomes could be the appropriate and sufficient criteria to assess a tool aimed to detect frailty in the community-dwelling elderly population. A two-step process (a first short questionnaire to detect frailty and a second longer questionnaire to define the care demand at individual level) could represent the appropriate pathway for planning care services at community level.

RESUMO

OBJECTIVES: Retention of subjects in HIV treatment programmes is crucial for the success of treatment. We evaluated retention/loss to follow-up (LTFU) in subjects receiving established care in Malawi. METHODS: Data for HIV-positive patients registered in Drug Resource Enhancement Against AIDS and Malnutrition centres in Malawi prior to 2014 were reviewed. Visits entailing HIV testing/counselling, laboratory evaluations, nutritional evaluation/supplementation, community support, peer education, and antiretroviral (ART) monitoring/pharmacy were noted. LTFU was defined as > 90 days without an encounter. Parameters potentially associated with LTFU were explored, with univariate/multivariate logistic regression analyses being performed. RESULTS: Fifteen thousand and ninety-nine patients registered before 2014; 202 (1.3%) were lost to follow-up (LTFU) (1.3%). Nine (0.5%) of 1744 paediatric patients were LTFU vs. 1.4% (n = 193) of 13 355 adults (P < 0.001). Subjects who were LTFU had fewer days in care than retained subjects (1338 vs. 1544, respectively; P < 0.001) and a longer duration of ART (1530 vs. 1300 days, respectively; P < 0.001). Subjects who were LTFU had higher baseline HIV viral loads (P = 0.016) and higher body mass indexes (P < 0.001), were more likely to live in urban settings (88% of patients who were LTFU lived in urban settings) with better housing [relative risk (RR) 2.3; 95% confidence interval (CI) 1.67-3.09; P < 0.001], and were more likely to be educated (RR 1.88; 95% CI 1.42-2.50; P < 0.001). Distance to the centre and cost of transportation were associated with LTFU (RR 3.4; 95% CI 2.84-5.37; P < 0.001), as was absence of a maternal figure (RR 1.57; 95% CI 1.17-2.09; P < 0.001). Viral load, distance index, education and a maternal figure were predictive of LTFU. CONCLUSIONS: Educated, urbanized HIV-infected adults living far from programme centres are at high risk of LTFU, particularly if there is no maternal figure in the household. These variables must be taken into consideration when developing retention strategies.

RESUMO

The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The outcomes and impact of synergies are using the Monitoring and Assessment Framework for the EIP on AHA (MAFEIP). Eight proposals for synergies have been approved by the Task Force: Five cross-cutting synergies which can be used for all current and future synergies as they consider overarching domains (appropriate polypharmacy, citizen empowerment, teaching and coaching on AHA, deployment of synergies to EU regions, Responsible Research and Innovation), and three cross-cutting synergies focussing on current Action Group activities (falls, frailty, integrated care and chronic respiratory diseases).

RESUMO

Aim of this paper is to describe the protocol of the study "Impact of a Community-based Program on Prevention and Mitigation of Frailty in community-dwelling older adults" developed in the framework of the European Innovation Partnership on Active and Healthy Ageing. This proposal has been developed by the Partnership Action groups on frailty, fall prevention and polypharmacy in older. The proposal wants to assess the impact of community-based programs aimed to counteract three main outcomes related to frailty: hospitalization, institutionalization and death. Bringing together researchers from seven European countries, the proposal aims to achieve the critical mass and the geographical extension enough to provide information useful to all older European citizens. An observational study will be carried out to calculate the incidence of the different outcomes in relation to the various interventions that will be assessed; results will be compared with data coming from already established national, regional and local dataset using the observed/expected approach. The sample will be made up by at least 2000 citizens for each outcome. All the citizens will be assessed at the baseline with two multidimensional questionnaires: the RISC questionnaire and the Short Functional Geriatric Evaluation questionnaire. The outcomes will be assessed every six-twelve months.

RESUMO

BACKGROUND: The population over 64 years of age is the main user of acute hospital care services. The elderly admission rates represent a marker for the appropriateness of the model of care. The aim of this study was to assess trends and determinants of acute in-patient care among the elderly in Italy between 2001 and 2011. STUDY DESIGN: Retrospective analysis of data included in the Italian Hospital Discharge Form Database. METHODS: Data from the Italian Hospital Discharge Form Database, Italian Ministry of Health, for the years 2001, 2006 and 2011 were analyzed for individuals over 64 years of age. Inpatient admission (> 1 day) rates across Italian Regions were calculated and compared with demographic variables and out-of-hospital care indicators. Univariate and multivariate analysis were used to determine independent relationship among variables. RESULTS: From 2001 to 2011 the elderly hospital admission rate decreased from 302.1/1,000 in 2001, to 222.4 in 2011, accounting for an overall decrease of about 28%. The decline in admission rates was less pronounced among individuals > 74 y (26.4%) than among those 65-74 y (32.1%). Hospitalization rates decreased in all Italian administrative regions between 2001 and 2011, even if the hospitalization rates in 2011 were still very different through the different Italian regions, ranging from 180.3/1,000 in Piedmont to 278.1/1,000 in Molise for people > 64 y. The multivariate linear regression was statistically significant in explaining the variations in hospitalization rates among the different Italian administrative regions (F: 3.637; p = 0.024; adjusted R2 = 0.57) and pointed to the role played by the proportion of the elderly (as percentage of the total population, p=0.043) and the rate of variation of acute care beds from 2004 to 2011 (p=0.001). Variables related to community-based care did not show any association with the hospital admissions rate among the elderly. CONCLUSIONS: The trend toward decline in elderly inpatient admissions is still present in 2011 as it was in 2001. Determinants of elderly hospital care in Italy are related to the increased number of elderly individuals and the reduction of hospital beds. Out-of-hospital care does not correlate with the variation of in-patient care so the overall care appropriateness could be negatively affected.

RESUMO

INTRODUCTION: In the Lazio Region (Central Italy) the Emergency Care network has been recently re-arranged in order to improve the effectiveness of care. The aim of this paper is to assess the impact of stroke patient care on both cost and organization of the hospital of Palestrina (Lazio Region). METHODOLOGY: An analysis of cost and path of care of all stroke patients (239) with stroke attending the hospital in 2010 has been carried out. RESULTS: The care was more expensive than the one offered to the stroke patients attending the "Hospital at Home" service managed by the San Giovanni Battista Hospital in Turin; moreover the care was incomplete because of the lack of rehabilitation services in the hospital catchment area. CONCLUSION: The care model offered to stroke patient hit by stroke in Palestrina needs to be deeply revised.

RESUMO

Smoking still represents a huge public health problem. Millions of children suffer the detrimental effects of passive smoking. An increasing number of countries have recently issued laws to regulate smoking in public places. Instead, homes remain a site where children are dangerously exposed to environmental tobacco smoke (ETS). The combination of tobacco smoke pollutants which remain in an indoor environment, the so-called 'third-hand smoke' (THS), represent a new concept in the field of tobacco control. THS consists of pollutants that remain on surfaces and in dust after tobacco has been smoked, are re-emitted into the gas-phase, or react with other compounds in the environment to form secondary pollutants. Indoor surfaces can represent a hidden reservoir of THS constituents that could be re-emitted long after the cessation of active smoking. Human exposure to THS pollutants has not yet been thoroughly studied. Infants and children are more prone to the risks related to THS exposure than adults because they typically spend more time indoors and have age-specific behaviours that may expose them to potential health hazards from THS. Further investigations are warranted to study the health effects of THS relevant to different exposure pathways and profiles. It would also be very important to evaluate how THS may affect the lung development through the in utero exposure during the pre-natal life. We aimed at reviewing recent findings published about THS, with special reference to the effects on children's health.

RESUMO

OBJECTIVE: The possibility of depicting through ultrasound (US) the nerve and its surroundings should be very useful in traumatic nerve lesion (TNL) management. Our study aimed at evaluating the contribution of US as complementary tool in a neurophysiological laboratory for the diagnosis and management of TNL. METHODS: A total of 112 nerves from 98 consecutive patients with clinical suspicion of TNL were considered. Two independent and blinded clinicians, different from the examiners performing electrodiagnosis and US, classified clinical, neurophysiological and US findings and classified the contribution of US as follows: 'contributive' and 'non-contributive' if US confirmed the clinical and neurophysiological diagnosis or if US findings were unremarkable. RESULTS: US was 'contributive' (strongly modified the diagnostic and therapeutic path) in 58% of cases (n: 65) providing information on therapeutic approach (immediate or delayed surgery), diagnosis and follow-up. US specifically contributed to the (1) assessment of nerve continuity/discontinuity, hence neurotmesis/axonotmesis; (2) identification of aetiology; and (3) demonstration of multiple sites of damage. US was contributive mainly in cases with neurophysiological evidence of complete axonal damage. CONCLUSIONS: US should be used, when available, in all patients in whom TNL is suspected as it provides a more comprehensive diagnosis than neurophysiologic studies alone. Anatomical information is often crucial for choosing the most appropriate therapeutic strategies (and for surgical planning). SIGNIFICANCE: US can improve the outcome of TNL.

RESUMO

BACKGROUND AND PURPOSE: Recently, ultrasound (US) has been used to assess the peripheral nervous system; however, there is no real study about its possible significant role in routine practice. Our study aims to assess the contribution of US as a routine tool in a neurophysiological laboratory. METHODS: The study assesses 130 patients who presented clinical suspicion of peripheral nerve diseases, excluding motor neuron disease, radiculopathy, hereditary and acquired polyneuropathy. All patients were clinically, neurophysiologically and sonographically assessed in the same session by the same neurologist/neurophysiologist. To avoid interpretation bias, two independent and blinded clinicians, different than the examiners performing electrodiagnosis and US, reviewed clinical, neurophysiological and US findings (also data about follow-up, when available) and classified the contribution of US as follows: Contributive (US had influence on the diagnostic and therapeutic strategies), Confirming (US confirmed the clinical and neurophysiological diagnosis), Non-Confirming (US findings were normal) and Incorrect (US findings led to incorrect diagnosis). RESULTS: US impacted, namely modified the diagnostic and therapeutic path in 42.3% of cases (55 patients); US had a confirmatory role in 40% (52 patients); US did not confirm clinical and neurophysiological diagnosis in 17.7% (23 cases); no incorrect US findings were observed. CONCLUSION: US complements neurophysiological assessment even in routine practice, and this confirms the increasing interest in US for a multidimensional evaluation of peripheral nerve system diseases.

RESUMO

Many different approaches have been proposed for the challenging problem of visually analyzing large networks. Clustering is one of the most promising. In this paper, we propose a new clustering technique whose goal is that of producing both intracluster graphs and intercluster graph with desired topological properties. We formalize this concept in the (X,Y) -clustering framework, where Y is the class that defines the desired topological properties of intracluster graphs and X is the class that defines the desired topological properties of the intercluster graph. By exploiting this approach, hybrid visualization tools can effectively combine different node-link and matrix-based representations, allowing users to interactively explore the graph by expansion/contraction of clusters without loosing their mental map. As a proof of concept, we describe the system Visual Hybrid (X,Y)-clustering (VHYXY) that implements our approach and we present the results of case studies to the visual analysis of social networks.
