Validation of the newly developed Advanced Practice Nurse Task Questionnaire: A national survey

AIM

To describe psychometric validation of the newly developed Advanced Practice Nurse Task Questionnaire.

DESIGN

Cross-sectional quantitative study.

METHODS

The development of the questionnaire followed an adapted version of the seven steps described in the guide by the Association for Medical Education in Europe. A nationwide online survey tested the construct and structural validity and internal consistency using an exploratory factor analysis, Cronbach's alpha coefficient and a Kruskal-Wallis test to compare the hypotheses.

RESULTS

We received 222 questionnaires between January and September 2020. The factor analysis produced a seven-factor solution as suggested in Hamric's model. However, not all item loadings aligned with the framework's competencies. Cronbach's alpha of factors ranged between .795 and .879. The analysis confirmed the construct validity of the Advanced Practice Nurse Task Questionnaire. The tool was able to discriminate the competencies of guidance and coaching, direct clinical practice and leadership across the three advanced practice nurse roles clinical nurse specialist, nurse practitioner or blended role.

CONCLUSION

A precise assessment of advanced practice nurse tasks is crucial in clinical practice and in research as it may be a basis for further refinement, implementation and evaluation of roles.

IMPACT

The Advanced Practice Nurse Task Questionnaire is the first valid tool to assess tasks according to Hamric's model of competencies independently of the role or the setting. Additionally, it distinguishes the most common advanced practice nurse roles according to the degree of tasks in direct clinical practice and leadership. The tool may be applied in various countries, independent of the degree of implementation and understanding of advanced nursing practice.

REPORTING METHOD

The STARD 2015 guideline was used to report the study.

Participatory development and implementation of a dementia care pathway with intervention bundles in acute care during the coronavirus pandemic: A process evaluation study

AIMS

To explore the implementation of a dementia care pathway in an acute care setting.

BACKGROUND

Dementia care in acute settings is often constrained by contextual factors. We developed an evidence-based care pathway with intervention bundles, and implemented it on two trauma units, with the aim to empower staff and improve quality care.

DESIGN

Process evaluation using quantitative and qualitative methods.

METHODS

Pre-implementation, unit staff completed a survey (n = 72) assessing family and dementia care skills and level of evidence-based dementia care. Post-implementation, champions (n = 7) completed the same survey, with additional questions on acceptability, appropriateness and feasibility, and participated in a focus group interview. Data were analysed using descriptive statistics and content analysis guided by the Consolidated Framework for Implementation Research (CFIR).

REPORTING GUIDELINE

Standards for Reporting Qualitative Research Checklist.

RESULTS

Pre-implementation, staff's perceived skills in family and dementia care were moderate overall, with high skills in 'building relationships' and 'sustaining personhood'. Evidence-based interventions were delivered seldom to frequent, with 'individualized care' scoring lowest and 'assessing cognition' scoring highest. Implementation of the care pathway/intervention bundles was overshadowed by the pandemic, and failed due to major organisational- and process-related barriers. Acceptability scored highest and feasibility lowest, with concerns relating to complexity and compatibility of pathways/bundles when introduced into clinical routines.

CONCLUSIONS

Our study implies that organisational and process factors are the most influential determinants to the implementation of dementia care in acute settings. Future implementation efforts should draw on the evolving evidence within implementation science and dementia care research to ensure effective integration and improvement process.

RELEVANCE TO CLINICAL PRACTICE

Our study provides important learning around improving care for persons with dementia and their families in hospitals.

PATIENT OR PUBLIC CONTRIBUTION

A family caregiver was involved in the development of the education and training programme.

Nurse-patient interaction during the Covid-19 pandemic: Creating and maintaining an interactive space for care

AIMS

To explore nurse-patient interactions during the Covid-19 pandemic from both nurses' and patients' perspectives.

DESIGN

Qualitative study using constructive grounded theory.

METHODS

A total of 34 patients and 49 nurses from acute and home care settings participated in individual or focus group interviews between December 2020 and May 2021. Data were analysed by a team of researchers using coding, memo-writing, theoretical sampling and constant comparison and integration.

RESULTS

We identified the creation and maintenance of an interactive space as the main social process. This interactive space was shaped by the care context and the course of the pandemic. For nurses, four factors were key, namely protecting oneself and others, navigating communication barriers, adapting nursing actions to the evolving situation, and providing emotional care work. Patients experienced attentive caring relationships with nurses and felt that, for the most part, their individual needs had been met despite the pandemic challenges.

CONCLUSION

Nurses and patients created an interactive space in which they were able to provide and receive the necessary care. Maintaining the interactive space was often challenging, and required an intentional effort by nurses, particularly in acute care settings. The findings illustrate that nurses ensured the provision of necessary care even during a public health crisis, thereby enabling patient access to good quality care.

IMPACT

Nurse-patient relationships are important for effective, person-centred care delivery. Despite the pandemic challenges, nurses managed to uphold their caring imperative and ensure quality care. Findings provide further insights on the importance of nurse-patient interaction in maintaining quality care. They inform models of nursing care delivery and strategies to support quality care during public health crises.

Effects of tall man lettering on the visual behaviour of critical care nurses while identifying syringe drug labels: a randomised in situ simulation

BACKGROUND

Patients in intensive care units are prone to the occurrence of medication errors. Look-alike, sound-alike drugs with similar drug names can lead to medication errors and therefore endanger patient safety. Capitalisation of distinct text parts in drug names might facilitate differentiation of medication labels. The aim of this study was to test whether the use of such 'tall man' lettering (TML) reduces the error rate and to examine effects on the visual attention of critical care nurses while identifying syringe labels.

METHODS

This was a prospective, randomised in situ simulation conducted at the University Hospital Zurich, Zurich, Switzerland. Under observation by eye tracking, 30 nurses were given 10 successive tasks involving the presentation of a drug name and its selection from a dedicated set of 10 labelled syringes that included look-alike and sound-alike drug names, half of which had TML-coded labels.Error rate as well as dwell time, fixation count, fixation duration and revisits were analysed using a linear mixed-effects model analysis to compare TML-coded with non-TML-coded labels.

RESULTS

TML coding of syringe labels led to a significant decrease in the error rate (from 5.3% (8 of 150 in non-TML-coded sets) to 0.7% (1 of 150 in TML-coded sets), p<0.05). Eye tracking further showed that TML affects visual attention, resulting in longer dwell time (p<0.01), more and longer fixations (p<0.05 and p<0.01, respectively) on the drug name as well as more frequent revisits (p<0.01) compared with non-TML-coded labels. Detailed analysis revealed that these effects were stronger for labels using TML in the mid-to-end position of the drug name.

CONCLUSIONS

TML in drug names changes visual attention while identifying syringe labels and supports critical care nurses in preventing medication errors.

First Testing of Literature-Based Models for Predicting Increase in Body Weight and Adipose Tissue Mass After Kidney Transplantation

Introduction: Weight gain is a risk factor for poor clinical outcomes following kidney transplantation. Research Question: This study's aim was a first testing of 2 models to identify patients early after kidney transplantation who are at risk for weight gain and increase in adipose tissue mass in the first year after kidney transplantation. Design: The literature-based models were evaluated on longitudinal data of 88, respectively 79 kidney transplant recipients via ordinary and Firth regression, using gains ≥ 5% in weight and adipose tissue mass respectively as primary and secondary endpoints. Results: The models included physical activity, smoking cessation at time of kidney transplantation, self-reported health status, depressive symptomatology, gender, age, education, baseline body mass index and baseline trunk fat as predictors. Area under the curve was 0.797 (95%-CI 0.702 to 0.893) for the weight model and 0.767 (95%-CI 0.656 to 0.878) for the adipose tissue mass model-showing good, respectively fair discriminative ability. For weight gain ≥ 5%, main risk factors were smoking cessation at time of transplantation (OR 16.425, 95%-CI 1.737-155.288) and better self-reported baseline health state (OR 1.068 for each 1-unit increase, 95%-CI 1.012-1.128). For the adipose tissue mass gain ≥ 5%, main risk factor was overweight/obesity (BMI ≥ 25) at baseline (odds ratio 7.659, 95%-CI 1.789-32.789). Conclusions: The models have potential to assess patients' risk for weight or adipose tissue mass gain during the year after transplantation, but further testing is needed before implementation in clinical practice.

Delirium screening in an acute care setting with a machine learning classifier based on routinely collected nursing data: A model development study

Delirium screening in acute care settings is a resource intensive process with frequent deviations from screening protocols. A predictive model relying only on daily collected nursing data for delirium screening could expand the populations covered by such screening programs. Here, we present the results of the development and validation of a series of machine-learning based delirium prediction models. For this purpose, we used data of all patients 18 years or older which were hospitalized for more than a day between January 1, 2014, and December 31, 2018, at a single tertiary teaching hospital in Zurich, Switzerland. A total of 48,840 patients met inclusion criteria. 18,873 (38.6%) were excluded due to missing data. Mean age (SD) of the included 29,967 patients was 71.1 (12.2) years and 12,231 (40.8%) were women. Delirium was assessed with the Delirium Observation Scale (DOS) with a total score of 3 or greater indicating that a patient is at risk for delirium. Additional measures included structured data collected for nursing process planning and demographic characteristics. The performance of the machine learning models was assessed using the area under the receiver operating characteristic curve (AUC). The training set consisted of 21,147 patients (mean age 71.1 (12.1) years; 8,630 (40.8%) women|) including 233,024 observations with 16,167 (6.9%) positive DOS screens. The test set comprised 8,820 patients (median age 71.1 (12.4) years; 3,601 (40.8%) women) with 91,026 observations with 5,445 (6.0%) positive DOS screens. Overall, the gradient boosting machine model performed best with an AUC of 0.933 (95% CI, 0.929 - 0.936). In conclusion, machine learning models based only on structured nursing data can reliably predict patients at risk for delirium in an acute care setting. Prediction models, using existing data collection processes, could reduce the resources required for delirium screening procedures in clinical practice.

Development of health care workers' mental health during the SARS-CoV-2 pandemic in Switzerland: two cross-sectional studies

BACKGROUND

Virus outbreaks such as the current SARS-CoV-2 pandemic are challenging for health care workers (HCWs), affecting their workload and their mental health. Since both, workload and HCW's well-being are related to the quality of care, continuous monitoring of working hours and indicators of mental health in HCWs is of relevance during the current pandemic. The existing investigations, however, have been limited to a single study period. We examined changes in working hours and mental health in Swiss HCWs at the height of the pandemic (T1) and again after its flattening (T2).

METHODS

We conducted two cross-sectional online studies among Swiss HCWs assessing working hours, depression, anxiety, and burnout. From each study, 812 demographics-matched participants were included into the analysis. Working hours and mental health were compared between the two samples.

RESULTS

Compared to prior to the pandemic, the share of participants working less hours was the same in both samples, whereas the share of those working more hours was lower in the T2 sample. The level of depression did not differ between the samples. In the T2 sample, participants reported more anxiety, however, this difference was below the minimal clinically important difference. Levels of burnout were slightly higher in the T2 sample.

CONCLUSIONS

Two weeks after the health care system started to transition back to normal operations, HCWs' working hours still differed from their regular hours in non-pandemic times. Overall anxiety and depression among HCWs did not change substantially over the course of the current SARS-CoV-2 pandemic.

Burnout, depression and anxiety among Swiss medical students - A network analysis

It is well established that burnout in medical students is associated with depression and anxiety at a syndromal level. Moreover, there is an ongoing debate about the extent to which burnout overlaps with depression and anxiety. The emerging network approach to psychopathology offers a new perspective on the interrelations between mental disorders focusing on symptom-level association. In this cross-sectional study, we exploratively investigated the associations among burnout, depression, and anxiety in 574 swiss medical students using a network analytic approach for the first time. Symptoms of depression and anxiety were assessed with the Patient Health Questionnaire and Generalized Anxiety Disorder respectively. Burnout was assessed with two single-item questions, one referring to emotional exhaustion and the other to depersonalization. We found a dense network in which at least one dimension of burnout was related to eleven of the sixteen included symptoms. This suggests that burnout is closely related to depression and anxiety but also has its own characteristics. Notably, suicidal ideation was not associated with either emotional exhaustion or depersonalization after adjusting for the influence of the remaining symptoms of anxiety and depression. Hence, the well-documented relationship between burnout and suicidal ideation in medical students may be entirely mediated by the experience of anxiety and depression. Hence, the well-documented relationship between burnout and suicidal ideation in medical students might be fully mediated by the experience of anxiety and depression. The collection of the sample after the first wave of infections during the SARS-CoV2 pandemic and the non-representativeness of the investigated sample limit the study's generalizability.

[Differences in epaAC© in heart failure patients with or without readmission: A retrospective case-control study]

Differences in epaAC© in heart failure patients with or without readmission: a retrospective case-control study Abstract. Background: Heart failure is one of the most frequent reasons for hospitalization in elderly people. In heart failure, approximately 22.8 % of hospitalised patients are rehospitalised within 30 days. The nursing assessment tool epaAC could provide information on risk factors for readmission. Aim: The aim of this study was to identify possible group differences in the items and scores of the epaAC discharge assessment with regard to the endpoint of unplanned readmissions within 30 days after discharge from index-hospitalisation. Methods: Using a retrospective case-control design, differences in the epaAC variables were investigated by descriptive and comparative statistics. Chi-square test, Wilcoxon test and t-test were performed with two-sided alpha level α < 0.05. Alpha error accumulation was accounted for by Benjamini & Hochberg correction. Results: No significant group differences were found in all items and scores of the discharge epaAC. There is only weak evidence that the presence of acute respiratory impairment at time of discharge is higher in the patient with rehospitalisation than in those without rehospitalisation. Conclusions: The items and scores of the nursing assessment instrument epaAC did not significantly differ between patients with or without 30-days readmission. Further exploration to assess the epaAC's potential to predict rehospitalisation in heart failure is needed.

Predisposing and Precipitating Risk Factors for Delirium in Elderly Patients Admitted to a Cardiology Ward: An Observational Cohort Study in 1,042 Patients

Aim: Although the risk factors for delirium in general medicine are well-established, their significance in cardiac diseases remains to be determined. Therefore, we evaluated the predisposing and precipitating risk factors in patients hospitalized with acute and chronic heart disease.

Methods and Results: In this observational cohort study, 1,042 elderly patients (≥65 years) admitted to cardiology wards, 167 with and 875 without delirium, were included. The relevant sociodemographic and cardiac- and medical-related clusters were assessed by simple and multiple regression analyses and prediction models evaluating their association with delirium. The prevalence of delirium was 16.0%. The delirious patients were older (mean 80 vs. 76 years; p < 0.001) and more often institutionalized prior to admission (3.6 vs. 1.4%, p = 0.05), hospitalized twice as long (12 ± 10 days vs. 7 ± 7 days; p < 0.001), and discharged more often to nursing homes (4.8 vs. 0.6%, p < 0.001) or deceased (OR, 2.99; 95% CI, 1.53–5.85; p = 0.003). The most relevant risk factor was dementia (OR, 18.11; 95% CI, 5.77–56.83; p < 0.001), followed by history of stroke (OR, 6.61; 95% CI 1.35–32.44; p = 0.020), and pressure ulcers (OR, 3.62; 95% CI, 1.06–12.35; p = 0.040). The predicted probability for developing delirium was highest in patients with reduced mobility and institutionalization prior to admission (PP = 31.2%, p = 0.001). Of the cardiac diseases, only valvular heart disease (OR, 1.57; 95% CI, 1.01–2.44; p = 0.044) significantly predicted delirium. The patients undergoing cardiac interventions did not have higher rates of delirium (OR, 1.39; 95% CI 0.91–2.12; p = 0.124).

Conclusion: In patients admitted to a cardiology ward, age-related functional and cognitive impairment, history of stroke, and pressure ulcers were the most relevant risk factors for delirium. With regards to specific cardiological factors, only valvular heart disease was associated with risk for delirium. Knowing these factors can help cardiologists to facilitate the early detection and management of delirium.

Patient Satisfaction With the Quality of Counseling Provided by Advanced Practice Nurses Specialized in Multiple Sclerosis: A Quantitative Analysis

ABSTRACT

BACKGROUND: The challenges in dealing with multiple sclerosis (MS) have increased considerably in recent years. In addition to neurologists, MS nurse specialists are key to the management of MS patients, but there is a lack of evidence regarding their quality of counseling. METHODS: The data collection took place between October 2018 and March 2019 in the outpatient clinic of a university hospital. The quality of counseling was assessed using the APN-BQ, an instrument that contains 19 items that can be assigned to 4 dimensions. Participants were asked to rate their satisfaction on a scale from 0 to 3. General satisfaction was assessed on a scale from 0 to 100. RESULTS: The participants (n = 110) rated the quality of counseling and their general satisfaction high. The mean (SD) of the structure quality dimension was 2.64 (0.44), and satisfaction with length and frequency of consultations (2.53 [0.63]) scored better than outcome quality (1.99 [0.62]) and process quality (2.13 [0.60]). CONCLUSION: Overall, there was a high rate of satisfaction with the quality of counseling. In addition to the length and frequency of consultations, MS patients particularly appreciated the availability and expertise of MS nurse specialists.

Health Care Workers' Mental Health During the First Weeks of the SARS-CoV-2 Pandemic in Switzerland-A Cross-Sectional Study

Objective: The current SARS-CoV-2 pandemic poses various challenges for health care workers (HCWs). This may affect their mental health, which is crucial to maintain high quality medical care during a pandemic. Existing evidence suggests that HCWs, especially women, nurses, frontline staff, and those exposed to COVID-19 patients, are at risk for anxiety and depression. However, a comprehensive overview of risk and protective factors considering their mutual influence is lacking. Therefore, this study aimed at exploring HCWs' mental health during the SARS-CoV-2 pandemic in Switzerland, investigating the independent effect of various demographic, work- and COVID-related factors on HCWs' mental health. Methods: In an exploratory, cross-sectional, nation-wide online survey, we assessed demographics, work characteristics, COVID-19 exposure, and anxiety, depression, and burnout in 1,406 HCWs during the beginning of the SARS-CoV-2 pandemic in Switzerland. Network analysis was used to investigate the associations among the included variables. Results: Women (compared to men), nurses (compared to physicians), frontline staff (compared to non-frontline workers), and HCWs exposed to COVID-19 patients (compared to non-exposed) reported more symptoms than their peers. However, these effects were all small. Perceived support by the employer independently predicted anxiety and burnout after adjustment for other risk factors. Conclusion: Our finding that some HCWs had elevated levels of anxiety, depression, and burnout underscores the importance to systematically monitor HCWs' mental health during this ongoing pandemic. Because perceived support and mental health impairments were negatively related, we encourage the implementation of supportive measures for HCWs' well-being during this crisis.

Self-Care Index and Post-Acute Care Discharge Score to Predict Discharge Destination of Adult Medical Inpatients: Protocol for a Multicenter Validation Study

BACKGROUND

Delays in patient discharge can not only lead to deterioration, especially among geriatric patients, but also incorporate unnecessary resources at the hospital level. Many of these delays and their negative impact may be preventable by early focused screening to identify patients at risk for transfer to a post-acute care facility. Early interprofessional discharge planning is crucial in order to fit the appropriate individual discharge destination. While prediction of discharge to a post-acute care facility using post-acute care discharge score, the self-care index, and a combination of both has been shown in a single-center pilot study, an external validation is still missing.

OBJECTIVE

This paper outlines the study protocol and methodology currently being used to replicate the previous pilot findings and determine whether the post-acute care discharge score, the self-care index, or the combination of both can reliably identify patients requiring transfer to post-acute care facilities.

METHODS

This study will use prospective data involving all phases of the quasi-experimental study "In-HospiTOOL" conducted at 7 Swiss hospitals in urban and rural areas. During an 18-month period, consecutive adult medical patients admitted to the hospitals through the emergency department will be included. We aim to include 6000 patients based on sample size calculation. These data will enable a prospective external validation of the prediction instruments.

RESULTS

We expect to gain more insight into the predictive capability of the above-mentioned prediction instruments. This approach will allow us to get important information about the generalizability of the three different models. The study was approved by the institutional review board on November 21, 2016, and funded in May 2020. Expected results are planned to be published in spring 2021.

CONCLUSIONS

This study will provide evidence on prognostic properties, comparative performance, reliability of scoring, and suitability of the instruments for the screening purpose in order to be able to recommend application in clinical practice.

Acute care delivery to persons with cognitive impairment: a mixed method study of health professionals' care provision and associated challenges

Objectives: Cognitive impairment is common among older persons admitted to hospital and associated with adverse outcomes. Inadequate care has been widely reported, with health professionals tending to be ill-equipped to meet the specific needs of this patient group. This study aimed to investigate health professionals' care provision to persons with cognitive impairment and associated challenges.Design and Setting: A concurrent, cross-sectional mixed method study was conducted at two university-affiliated hospitals.Participants: A total of 339 health professionals participated in the study.Measurements: An online survey (n = 312) determined the extent to which health professionals perceived their care provision to be person-centered and evidence-based (POPAC-R), and experience distress in looking after this patient group (NPI-D). Four focus group interviews (n = 27) explored health professionals' experience of care provision.Results: More than half of the health professionals reported to act always or very frequently in person-centered and evidence-based ways, and two third experienced challenging behaviors as moderately to very distressing. Health professionals working in acute geriatric wards demonstrated statistically significant higher levels of person-centered and evidence-based care provision, and lower distress. Their caring practices pertained to building a relationship, addressing specific needs, involving family members, and working collaboratively.Conclusions: Findings suggest that geriatric models of care delivery support staff in meeting the needs of persons with cognitive impairment. Health professionals require an acute care culture that values relational, collaborative and coordinated care as essential to patient safety and quality of care, and supports the consistent implementation of evidence-based practices for this patient group.

Gesundheitsverhalten und Bedürfnisse von Menschen mit COPD während der COVID-19-Pandemie - Eine Dokumentenanalyse

Health behaviours and needs of people with COPD during COVID-19 pandemic: a document analysis Abstract. Background: The government's guidelines affected people with COPD on different levels during the COVID-19 pandemic. In addition to belonging to a group of particularly vulnerable persons, they had to adapt their health behaviours, in particular physical activity, to recommendations provided in order to prevent negative effects on disease progression. There is little knowledge regarding how this group of patients coped with these challenges during the COVID-19 pandemic.

OBJECTIVE

To describe the health behaviours and needs people with COPD convey during nursing phone consultations and which nursing interventions have been carried out.

METHODS

A document analysis of 50 nursing phone consultations was performed. The data were summarised descriptively and analysed thematically.

RESULTS

The main topics were the adaptation of physical activity, the implementation of the recommendations to the individual life situation, the detection of a COVID-19 infection and questions concerning the planning of medical appointments.

CONCLUSION

The COVID-19 pandemic poses additional challenges to the disease management of people with COPD. The increased need for care brought on by the pandemic was able to be met by the knowledge provided in the nursing phone consultations. What remains to be established is what role the consultations play in a sustainable change in behaviour and in dealing with negative emotions.

Family and health professional experience with a nurse-led family support intervention in ICU: A qualitative evaluation study

OBJECTIVES

To investigate family and health professional experience with a nurse-led family support intervention in intensive care.

DESIGN

Qualitative evaluation study.

SETTING

A twelve-bed surgical intensive care unit in a 900-bed University Hospital in Switzerland.

MAIN OUTCOME MEASURES

Data were collected through 16 semi-structured interviews with families (n = 19 family members) and three focus group interviews with critical care staff (n = 19) and analysed using content analysis strategies.

FINDINGS

Four themes related to the new family support intervention were identified. First, families and staff described it as a valuable and essential part of ICU care. Second, it facilitated staff-family interaction and communication. Third, from staff perspective, it promoted the quality of family care. Fourth, staff believed that the family support intervention enabled them to better care for families through increased capacity for developing and sustaining relationships with families.

CONCLUSIONS

An advanced practice family nursing role coupled with a family support pathway is an acceptable, appreciated and beneficial model of care delivery in the inttensive care unit from the perspective of families and critical care staff. Further research is needed to investigate the intervention's effectiveness in the intensive care unit.

Transduction patterns in the CNS following various routes of AAV-5-mediated gene delivery

Various administration routes of adeno-associated virus (AAV)-based gene therapy have been examined to target the central nervous system to answer the question what the most optimal delivery route is for treatment of the brain with certain indications. In this study, we evaluated AAV5 vector system for its capability to target the central nervous system via intrastriatal, intrathalamic or intracerebroventricular delivery routes in rats. AAV5 is an ideal candidate for gene therapy because of its relatively low level of existing neutralizing antibodies compared to other serotypes, and its broad tissue and cell tropism. Intrastriatal administration of AAV5-GFP resulted in centralized localized vector distribution and expression in the frontal part of the brain. Intrathalamic injection showed transduction and gradient expression from the rostral brain into lumbar spinal cord, while intracerebroventricular administration led to a more evenly, albeit relatively superficially distributed, transduction and expression throughout the central nervous system. To visualize the differences between localized and intra-cerebral spinal fluid administration routes, we compared intrastriatal to intracerebroventricular and intrathecal administration of AAV5-GFP. Together, our results demonstrate that for efficient transgene expression, various administration routes can be applied.

Advanced nursing practice in COPD exacerbations: the solution for a gap in Switzerland?

Aim

This study aimed to address the need for adaptation of the current model of chronic obstructive pulmonary disease (COPD) care in Switzerland, particularly in regard to acute exacerbations, and how far an integrated approach involving advanced nursing practice can meet those needs.

Methods

A state analysis guided by the PEPPA framework was initiated by the Pulmonology Clinic of University Hospital Zürich. Literature describing the current provision of COPD care regarding exacerbations in Switzerland and international qualitative studies describing the patient perspective were systematically searched and summarised. The health providers' perspective was investigated in three focus-group interviews.

Results

A lack of systematic and state-of-the-art support for patient self-management in Switzerland was described in literature and confirmed by the health providers interviewed. While care was assessed as being comprehensive and of good quality in each individual sector, such as inpatient, outpatient, rehabilitation and home settings, it was identified as being highly fragmented across sectors. The interview participants described day-to-day examples in which a lack of support in COPD self-management and fragmentation of care negatively affected the patients' disease management.

Conclusion

The necessity of coordinating the transition between healthcare sectors and self-management support and that these organisational boundaries should be addressed by a multi-professional team were identified. Initial evaluation indicates that advanced practice nurses potentially have the skill set to coordinate the team and address patients' self-management needs in complex patient situations. However, the legal foundation and a reimbursement system to ensure long-term implementation is not yet available.

Advanced practice nurses have the skills to meet needs in the treatment of #AECOPD, such as transition between healthcare sectors and systematic self-management support, but the legal and financial framework is not present in Switzerland yethttps://bit.ly/2wQysHV

Implementing Family Systems Care Through an Educational Intervention With Nurses and Midwives in Obstetrics and Gynecological Care: A Mixed-Methods Evaluation

This mixed-methods study examined Family Systems Care (FSC) implementation through a 1-day educational session combined with 4 months of guided application of FSC knowledge and skills in obstetrics and gynecology settings. Nurses and midwives' (n = 47) attitudes toward families and their practice skills with families were assessed before the educational intervention began (Time 0), after the completion of the 1-day educational session (Time 1), and after 4 months of the FSC guided implementation phase that included coaching and mentoring (Time 2). Four focus groups with the nurses and midwives explored their FSC implementation experiences. Participants reported an initial drive to implement FSC, which faltered over time. A perceived fit to the needs of families in obstetrics and gynecology, a supportive context, and facilitated learning on the units promoted FSC uptake. Participants understood FSC as: (a) involving family members in care, a practice they felt confident about; (b) assessing families' situations, needs, concerns, which were practices that were new and stressful; and (c) offering family nursing interventions, which they felt insufficiently prepared for. Practice skills in FSC increased after the 1-day educational session but decreased to baseline after the FSC guided implementation phase. Attitudes of the nurses and midwives toward the families did not change. Following the education and guided implementation, participants' ability to work with families in a relational, systemic way could not be fully established or sustained.

Hospital-based bereavement care provision: A cross-sectional survey with health professionals

BACKGROUND

An in-hospital death is a profound experience for those left behind and has been associated with family members' psychological morbidity. Supporting bereaved family members is an essential part of end-of-life care and includes attentive presence, information-giving, and emotional and practical support. The actual adoption of hospital-based bereavement care, however, remains little understood.

AIM

To investigate hospital-based bereavement care provision and associated barriers.

DESIGN

Cross-sectional survey using an online questionnaire.

SETTING/PARTICIPANTS

Health professionals (n = 196) from two University-affiliated acute and psychiatric hospitals in Switzerland.

RESULTS

The most frequent bereavement services (⩾40%) were viewing the deceased, giving information on available support, and making referrals; the most often named barriers were lack of time and organizational support. Acute care health professionals faced statistically significant more structural barriers (55.1% vs 21.4% lack of time, 47.8% vs 25.9% lack of organizational support) and felt insufficiently trained (38.4% vs 20.7%) compared to mental health professionals (p ⩽ 0.05). Nurses provided more immediate services compared to physicians, such as viewing the deceased (71.3% vs 49.0%) and sending sympathy cards (37.4% vs 16.3%) (p ⩽ 0.01). In contrast, physicians screened more often for complex bereavement disorders (10.2% vs 2.6%) and appraised bereavement care as beyond their role (26.5% vs 7.8%) (p ⩽ 0.05).

CONCLUSION

The study indicates that many barriers to bereavement care exist in hospitals. More research is required to better understand enabling and limiting factors to bereavement care provision. A guideline-driven approach to hospital-based bereavement care that defines best practice and required organizational support seems necessary to ensure needs-based bereavement care.

[Patients with psychiatric comorbidities in the acute hospital - a field of tension with interprofessional need for action - results from a pilot study]

Patients with psychiatric comorbidities in the acute hospital - a field of tension with interprofessional need for action - results from a pilot study Abstract. Background: Psychiatric comorbidities are frequent in patients hospitalized in an acute care hospital. They often remain undetected or, if diagnosed, neglected. As long as the somatic disease can be properly cared for and treated, this usually remains unproblematic. However, the situation can quickly tip over if psychiatric comorbidities interfere with care and treatment leading to a higher level of care and adverse consequences for patients. Aim: We investigated the need for action for this patient group from the nurses' perspective in a Swiss-German university hospital. Method: In two group discussions, nurses described intense situations, followed by an evaluation of determining factors, insights gained and measures taken to control these situations and prevent them. Results: Nurses experience the described situations as stressful and express a great need for action for themselves and for the interprofessional team. Key points are vigilance in everyday clinical practice, specific knowledge acquisition and an easily accessible local support system. Conclusions: In an acute care hospital, psychiatric comorbidities must be taken into account. However, this requires advanced skills and an organizational, interprofessional approach.

Capturing interprofessional collaboration between physicians and nurses in an acute care setting. A validation study of the revised German version of the Collaborative Practice Scales

The relevance of interprofessional collaboration (IPC) is widely acknowledged. Given the lack of a fully validated instrument in the German language for measuring the level of IPC, we built upon the current, albeit psychometrically weak, German-language version of the instrument to devise a new version with improved wording and for subsequent psychometric testing. In a tertiary hospital in German-speaking Switzerland, 160 physicians and 374 nurses completed the revised Collaborative Practice Scales in German (CPS-G) and additional scales regarding positive and negative activation at work and regarding job demands and job resources. A confirmatory factor analysis of the CPS-G was performed, and internal consistency estimates were computed. Partial correlations between the CPS-G and the additional scales were examined for criterion validity. The model fit of the CPS-G was good for physicians (χ²/df = 2.38, p < .001; CFI = .923; RMSEA = .051, 90%-CI (0.037-0.065)) and moderate for nurses (χ²/df = 5, p < .001; CFI = .919; RMSEA = .087, 90%-CI (0.072-0.102)) supporting the two-factor structure of the original English version. Reliability was acceptable in all sub-scales for physicians (inclusion, α = 0.79; consensus, α = 0.80) and nurses (assertiveness, α = 0.77; understanding α = 0.82). As expected, the CPS-G physicians' subscales correlated positively with positive activation and job resources and negatively with negative activation and job demands, albeit not always statistically significantly. Similar correlations were found with the CPS-G nurses' subscales other than in one instance. The CPS-G showed good construct and criterion validity and acceptable internal consistency. It consequently represents a valid instrument ready for application to measure the level of interprofessional collaboration between nurses and physicians in acute care settings.

The TransFLUas influenza transmission study in acute healthcare - recruitment rates and protocol adherence in healthcare workers and inpatients

Background

Detailed knowledge about viral respiratory disease transmission dynamics within healthcare institutions is essential for effective infection control policy and practice. In the quest to study viral transmission pathways, we aimed to investigate recruitment rates and adherence of healthcare workers (HCWs) and hospital inpatients with a study protocol that involves prospective surveillance based on daily mid-turbinate nasal swabs and illness diaries.

Methods

Single center prospective surveillance of patients and HCWs in three different hospital departments of a tertiary care center during an entire influenza season in Switzerland. Inpatients and acute care HCWs were asked to provide mid-turbinate nasal swabs and illness diaries on a daily basis. Study protocol adherence and recruitment rates were the primary outcomes of interest.

Results

A total 251 participants (59 (23.5%) health care workers and 192 (76.5%) inpatients) were recruited from three different hospital wards. Recruitment rates differed between HCWs (62.1% of eligible HCWs) and inpatients (32.5%; P < 0.001), but not within HCWs (P = 0.185) or inpatients (P = 0.301) of the three departments. The total number of study-days was 7874; 2321 (29.5%) for inpatients and 5553 (70.5%) for HCWs. HCWs were followed for a median of 96 days (range, 71–96 days) and inpatients for 8 days (range, 3–77 days). HCWs provided swabs on 73% (range, 0–100%) of study days, and diaries on 77% (range 0–100%). Inpatients provided swabs and diaries for 83% (range, 0–100%) of days in hospital. In HCWs, increasing age, working in internal medicine and longer duration of total study participation were positively associated with the proportion of swabs and diaries collected. Adherence to the study protocol was significantly lower in physicians as compared to nurses for both swabs (P = 0.042) and diaries (P = 0.033). In inpatients, no association between demographic factors and adherence was detected.

Conclusions Prospective surveillance of respiratory viral disease was feasible in a cohort of inpatients and HCWs over an entire influenza season, both in terms of recruitment rates and adherence to a study protocol that included daily specimen collection and illness diaries.

Adaption, benefit and quality of care associated with primary nursing in an acute inpatient setting: A cross-sectional descriptive study

AIMS

The aim of this study was to investigate the adoption of primary nursing and to determine the quality of primary nurse-led care in an acute inpatient setting.

DESIGN

Descriptive cross-sectional study.

METHODS

Participants included inpatients (N = 369) and nurses (N = 381). To assess adoption of primary nursing, patient records were analysed and an online survey of nurses was conducted from May-June 2017. To measure quality of nursing care, a structured questionnaire was administered to inpatients.

RESULTS

Patients reported high quality of individualized, responsive and proficient care, but lower levels of coordinated care. Most nurses agreed that primary nursing is beneficial for person-centred caring. However, only two-thirds found that it was practiced on their unit and only half of care planning activities were attributable to primary nurses.

CONCLUSION

While perceived as beneficial, adoption of primary nursing in clinical practice remains partial. Hence, primary nursing may not be enough to ensure continuity and coordination of acute care.

Safe swallowing and communicating for ventilated intensive care patients with tracheostoma: implementation of the Passy Muir speaking valve

Background: Between 4 to 45 % of intensive care patients suffer from prolonged ventilator dependence. Due to impeded weaning, verbal communication is impossible. The tracheal cannula affects breathing and swallowing. The Passy Muir speaking valve (PMV) allows patients on ventilators to speak. It counteracts pharyngeal as well as laryngeal desensitization and prevents an insufficient swallowing reflex. Aim and methods: To implement the PMV, we conducted a multiprofessional practice- and quality development project. The objective was to ensure safe swallowing and communicating for ventilated patients with tracheostoma. Results: Intensive care nurses, doctors and physiotherapists assessed patient safety as being high. In nine patients with 51 PMV applications, we observed three undesirable events in terms of dyspnea and oxygen desaturation. On one occasion, it was necessary to remove the PMV. Conclusion: A combination of mandatory training for the entire treatment team, presence of two professionals during PMV application, and a newly developed guiding document resulted in a high level of patient safety. By means of PMV, ventilated intensive care patients are able to communicate verbally and to swallow better. Complications can be identified early and solved effectively.

Quality of acute care for persons with cognitive impairment and their families: A scoping review

BACKGROUND

An increasing number of older persons with cognitive impairment use inpatient services for co-occurring acute illness. Research has demonstrated that persons with cognitive impairment face more adverse health outcomes during hospitalization than their age counterparts without cognitive impairment. As hospitals tend to be ill equipped to meet the complex care needs of this population, various initiatives underscore the need to better utilize existing evidence to improve quality of care.

OBJECTIVES

To map the extent of knowledge about quality of acute care in inpatient settings, and to synthesize knowledge on strategies to improve quality care for persons with cognitive impairment and their families.

DESIGN

A scoping review using Arksey and O'Malley's methodological framework.

DATA SOURCES

CINAHL and Medline were searched and reference lists of pertinent articles screened to identify publications regarding acute care for persons with cognitive impairment.

REVIEW METHODS

Two reviewers independently screened and identified publications based on eligibility criteria. Publications were included if they targeted acute care issues relating to persons with cognitive impairment 65 years or older, their family members, or health professionals caring for them, and were published after 2000 in English or German. Publications were read and data were extracted using a predefined template. Thematic analysis was conducted by two reviewers.

RESULTS

Of the 1445 identified publications, 66 were included. Quality of acute inpatient services pertained to structural (such as staff capacity and knowledge) and process dimensions (such as forming a caring relationship, assessing and intervening). Strategies identified to improve care quality included interventions at the point of care, such as specific tools and specialist roles to improve patient outcomes, as well as educational and training interventions to enable staff to care for this patient group.

CONCLUSIONS

There is a discrepancy between clearly defined best practice for persons with cognitive impairment utilising inpatient services, and the quality of care actually experienced by patients, family members, and staff. Research reveals a sobering picture of inadequate care and manifold challenges encountered by this patient group, family members and staff alike. Promising strategies to improve care quality target health professionals' knowledge and capacity to work with this group and include specific tools and models of care, such as specialist roles and units. Organisation-wide efforts to ensure quality care for this patient group are needed, as is further research to determine which implementation and intervention strategies achieve the most beneficial outcomes for all involved.

AAV5-miHTT gene therapy demonstrates suppression of mutant huntingtin aggregation and neuronal dysfunction in a rat model of Huntington's disease

Huntington’s disease (HD) is a fatal progressive neurodegenerative disorder caused by a mutation in the huntingtin (HTT) gene. To date, there is no treatment to halt or reverse the course of HD. Lowering of either total or only the mutant HTT expression is expected to have therapeutic benefit. This can be achieved by engineered micro (mi)RNAs targeting HTT transcripts and delivered by an adeno-associated viral (AAV) vector. We have previously showed a miHTT construct to induce total HTT knock-down in Hu128/21 HD mice, while miSNP50T and miSNP67T constructs induced allele-selective HTT knock-down in vitro. In the current preclinical study, the mechanistic efficacy and gene specificity of these selected constructs delivered by an AAV serotype 5 (AAV5) vector was addressed using an acute HD rat model. Our data demonstrated suppression of mutant HTT messenger RNA, which almost completely prevented mutant HTT aggregate formation, and ultimately resulted in suppression of DARPP-32-associated neuronal dysfunction. The AAV5-miHTT construct was found to be the most efficient, although AAV5-miSNP50T demonstrated the anticipated mutant HTT allele selectivity and no passenger strand expression. Ultimately, AAV5-delivered-miRNA-mediated HTT lowering did not cause activation of microglia or astrocytes suggesting no immune response to the AAV5 vector or therapeutic precursor sequences. These preclinical results suggest that using gene therapy to knock-down HTT may provide important therapeutic benefit for HD patients and raised no safety concerns, which supports our ongoing efforts for the development of an RNA interference-based gene therapy product for HD.

MR-guided parenchymal delivery of adeno-associated viral vector serotype 5 in non-human primate brain

The present study was designed to characterize transduction of non-human primate brain and spinal cord with AAV5 viral vector after parenchymal delivery. AAV5-CAG-GFP (1 × 10¹³ vector genomes per milliliter (vg ml⁻¹)) was bilaterally infused either into putamen, thalamus or with the combination left putamen and right thalamus. Robust expression of GFP was seen throughout infusion sites and also in other distal nuclei. Interestingly, thalamic infusion of AAV5 resulted in the transduction of the entire corticospinal axis, indicating transport of AAV5 over long distances. Regardless of site of injection, AAV5 transduced both neurons and astrocytes equally. Our data demonstrate that AAV5 is a very powerful vector for the central nervous system and has potential for treatment of a wide range of neurological pathologies with cortical, subcortical and/or spinal cord affection.

Older persons’ and their families’ experience with live-in foreign home care workers. A grounded theory study

Background: Live-in arrangements with migrant care workers have considerably increased over the last years since they allow older frail persons to age-in-place despite functional limitations. However, little is known about the ramifications live-in care arrangements for families. Aim: The aim of the study was to investigate families’ experience with live-in migrant care workers and indicators of quality from their perspective. Method: Constructivist grounded theory study with 22 families who were recruited via care agencies in the German-speaking part of Switzerland and participated in 29 individual or dyadic interviews. Results: Live-in care by migrant care workers has potentially positive ramifications for older persons and their families, but only so if families, first, reach a consensus about the need for the employment of migrant care workers; second, experience them as competent; and third, mutually forge relationships and negotiate daily life. A successful care arrangement occurs when there is a relational fit among those involved, which leaves families feeling cared for, safe and relieved. They experience a renewed stability in their family system, enriching relationships, and assuredness about the quality present in the care situation. Conclusions: A successful care arrangement is the result of relationships that have been actively created and a negotiated shared existence in a family-like network. It has a positive effect on the well-being of those receiving care and their family members. The family-like network needs competent support.

Unterstützung des Pflegeprozesses durch die elektronische Pflegeprozessdokumentation (UEPD)

Zusammenfassung. Hintergrund: Elektronische Pflegedokumentationssysteme mit hinterlegter standardisierter Pflegefachsprache erfassen den Pflegeprozess IT-gestützt. Sie haben das Potenzial, die Qualität der Dokumentation des Pflegeprozesses zu verbessern und die Pflegenden in dessen Durchführung zu unterstützen. Fragestellung/Ziel: Dieser Artikel beschreibt die Entwicklung und erste Validierung eines Instruments (UEPD), das die subjektiv wahrgenommene Unterstützung Pflegender in der Umsetzung des Pflegeprozesses durch eine elektronische Pflegeprozessdokumentation misst. Methode: Die Validität des UEPD wurde anhand einer Evaluationsstudie in einem Krankenhaus (n = 94) in der Deutschschweiz untersucht. Die psychometrische Testung des Instruments wurde anhand einer Hauptkomponentenanalyse durchgeführt. Ergebnisse: Die ersten Hinweise zur Validität des Instruments konnten vorgestellt werden. Die Analyse ergab eine stabile vier Faktorenstruktur (FS = 0,89) mit 25 Items, die Faktorladungen ≥ 0,50 aufwiesen. Die Skalen zeigten hohe interne Konsistenzen (Cronbachs α = 0,73 – 0,90). Die Hauptkomponentenanalyse zeigte folgende vier Dimensionen der Unterstützung: Beim Stellen von Pflegediagnosen und -zielen; beim Erfassen von Anamnese/Assessment und im Dokumentieren des Pflegeprozesses; in der Implementierung und Evaluation sowie im Informationsaustausch. Schlussfolgerungen: Die Ergebnisse sollen in größeren Stichproben sowie mit verschiedenen Dokumentationssystemen weitergetestet werden. In einem weiteren Schritt könnte das UEPD zum Vergleich verschiedener elektronischer Dokumentationssysteme eingesetzt werden.

Beratungsqualität von Pflegeexpertinnen-APN im spitalexternen Bereich (APN-BQ) – Psychometrische Testung des Instruments

Hintergrund: Patientenzentrierte und individuell ausgerichtete Angebote, wie die häusliche Beratung durch Pflegeexpertinnen-APN (Advanced Practice Nurses), eignen sich besonders, chronisch kranke alte Menschen in einer möglichst selbstständigen Lebensführung zu unterstützen. Methode: Um die Qualität einer patientenzentrierten Beratung zu evaluieren, wurde ein 23-Item Instrument entwickelt und seine psychometrischen Eigenschaften mit einer Stichprobe von 206 Personen, die 80 Jahre und älter waren getestet. Ziel: Ziel dieses Artikels ist es, die Entwicklung und Evaluation des APN-BQ zu beschreiben. Die psychometrische Testung des Instruments erfolgte anhand einer Hauptkomponentenanalyse mit Varimax-Rotation. Ergebnisse: Die Analyse ergab eine stabile vier Faktorenstruktur (FS = 0,91) mit 19 Items. Alle Faktoren hatten eine Faktorladung > 0,45. Die interne Konsistenz der Gesamtskala ergab einen Wert von Cronbachs alpha 0,86. Die hohe Rücklaufquote der Fragebogen und die Tatsache, dass 98,8 % der Fragen beantwortet wurden, bestätigten die Anwendungsfreundlichkeit und Akzeptanz des Instruments. Schlussfolgerungen: Das APN-BQ erwies sich als zuverlässiges und in Bezug auf Inhalt und Konstrukt valides Instrument, die Struktur-, Prozess- und Ergebnisqualität einer patientenzentrierten Beratungsintervention in der gemeindenahen Versorgung sowie das Ausmaß der Partizipation und Selbstbefähigung (Empowerment) der zu Beratenden zu messen.

AAV-mediated in vivo knockdown of luciferase using combinatorial RNAi and U1i

RNA interference (RNAi) has been successfully employed for specific inhibition of gene expression; however, safety and delivery of RNAi remain critical issues. We investigated the combinatorial use of RNAi and U1 interference (U1i). U1i is a gene-silencing technique that acts on the pre-mRNA by preventing polyadenylation. RNAi and U1i have distinct mechanisms of action in different cellular compartments and their combined effect allows usage of minimal doses, thereby avoiding toxicity while retaining high target inhibition. As a proof of concept, we investigated knockdown of the firefly luciferase reporter gene by combinatorial use of RNAi and U1i, and evaluated their inhibitory potential both in vitro and in vivo. Co-transfection of RNAi and U1i constructs showed additive reduction of luciferase expression up to 95% in vitro. We attained similar knockdown when RNAi and U1i constructs were hydrodynamically transfected into murine liver, demonstrating for the first time successful in vivo application of U1i. Moreover, we demonstrated long-term gene silencing by AAV-mediated transduction of murine muscle with RNAi/U1i constructs targeting firefly luciferase. In conclusion, these results provide a proof of principle for the combinatorial use of RNAi and U1i to enhance target gene knockdown in vivo.

[SpitexPlus: assessment of and specialised nursing care for elderly and their families living in the community]

Current demographic developments and the high prevalence of chronic conditions require new approaches to nursing care of the elderly population in Switzerland. New care models need to be developed that go beyond traditional nursing practice with its focus on the individual. Existing preventive home visit and case management programmes have mostly focussed on the young old with the goal to maintain functional health and prevent institutionalisation. Families, who play a crucial role in the care of the elderly at home, were not included. The purpose of this article is to describe the development of the SpitexPlus Project, which is directed at people 80 years and older and their families, irrespective of their health status and social situation. It aims to improve self-care capabilities and quality of life in people 80+ and their families and to enable them to manage the challenges of daily life at home. Evidence based nursing interventions, based on the principles of health promotion, empowerment, family centeredness, and partnership were developed. The development of the programme phases, interventions, and the role of the advanced practice nurses are described in detail. Potential benefits for nursing practice are delineated.

A systematic review of valerian as a sleep aid: safe but not effective

Valerian is an herb that is widely available in a variety of commercial preparations and is commonly used as a sleep aid. A recent systematic review and meta-analysis of valerian concluded that evidence in support of the effectiveness of the herb was inconclusive. Therefore, in an effort to more closely examine this issue, a systematic review was conducted to examine the evidence on the efficacy of valerian as a sleep aid with specific attention to the type of preparations tested and the characteristics of the subjects studied. A comprehensive search of studies investigating valerian was conducted through computerized databases and hand searches of reference lists. Standardized forms were used to summarize findings and standardized criteria were used to assess study quality. Out of 592 articles initially identified, a total of 36 articles describing 37 separate studies met criteria for review: 29 controlled trials evaluated for both efficacy and safety, and eight open-label trials evaluated for safety only. Most studies found no significant differences between valerian and placebo either in healthy individuals or in persons with general sleep disturbance or insomnia. None of the most recent studies, which were also the most methodologically rigorous, found significant effects of valerian on sleep. Overall, the evidence, while supporting that valerian is a safe herb associated with only rare adverse events, does not support the clinical efficacy of valerian as a sleep aid for insomnia.

Regulated expression of the interferon-β gene in mice

A single plasmid regulated expression vector based upon a mifepristone-inducible two plasmid system, termed pBRES, has been constructed and tested in mice using murine interferon-b (mIFNb) as the transgene. The expression of mIFNb in the circulation was followed by measuring the systemic induction of IP-10, a validated biomarker for mIFNb in mice. Long-term, inducible expression of mIFNb was demonstrated following a single intramuscular (i.m.) injection of the pBRES mIFNb plasmid vector into the hind limb of mice. Induction of mIFNb expression was achieved by administration of the small molecule inducer, mifepristone (MFP). Plasmid DNA and mIFNb mRNA levels in the injected muscles correlated with mIFNb expression as monitored by IP-10 over a 3-month time period. Renewable transgene expression was achieved following repeat administration of the plasmid at 3 months following the first plasmid injection. A dose-dependent increase in expression was demonstrated by varying the amount of injected plasmid or the amount of the inducer administered to the mice. Finally, the pBRES plasmid expressing mIFNb under control of the inducer, MFP, was shown to be efficacious in a murine model of experimental allergic encephalomyelitis, supporting the feasibility of gene-based therapeutic approaches for treating diseases such as multiple sclerosis.

Complexity in caring for an ageing heart failure population: concomitant chronic conditions and age related impairments

The complexity of caring for the ageing heart failure (HF) population is further complicated by concomitant chronic conditions (i.e., polypharmacy, depression), age related impairments (i.e., hearing, visual and cognitive impairments, impairments in activities of daily living (ADL/IADL), and other issues (e.g., health illiteracy, lack of social support). This paper provides an overview of these risk factors, outlines how they individually and in interplay endanger favourable outcome by putting patients at risk for poor self-management. Moreover, suggestions are made on how these issues could be addressed and integrated in heart failure management by applying gerontological care principles in caring for the ageing heart failure population.

Responses and experiences after radical prostatectomy: perceptions of married couples in Switzerland

The purpose of this qualitative study was to explore the responses and experiences of a sample of Swiss men after radical prostatectomy and their intimate partners. Interviews were conducted with 10 couples and analyzed using constant comparative method. Getting a grip on it was the core process that was developed. Men focused on regaining control over their lives, urinary and erectile function while wives efforts focused on being there. The results revealed that current clinical practice of follow up at 3 months may not address the serious deficits in the patient's ability to "get a grip" on incontinence and other complications of surgery.
