Reliability and Validity of the Chinese Version of the Perceived Access to Health Care Questionnaire

Background: The Perceived Access to Health Care Questionnaire (PAHCQ) is the latest specific tool used to evaluate patients' accessibility to the health system. Objectives: This study aimed to translate and verify the item analysis, test-retest reliability, content validity, construct validity, and known-group analysis of the PAHCQ in a Chinese population. Methods: This study developed and validated the Chinese version of the PAHCQ. The translation of the PAHCQ was based on the back translation of Brislin. This study used simple random sampling to include a sample of 591 subjects in Jiangsu, China. Item analysis was used to verify the questionnaire's expert consistency and cultural adaptation. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the effectiveness of the structure. Internal consistency was determined using Cronbach's α, and item validity and test-retest reliability were analyzed. Results: The CFA results indicated that the modified PAHCQ is reasonable. The Cronbach alpha value of the PAHCQ was 0.96. The correlation coefficients for the six domains in test-retest reliability were between 0.67 and 0.91. Comparison of the total PAHCQ scores among participants in different groups of age, gender, maternal status, education level, per capita monthly income, and CCI levels showed statistically significant differences (P < 0.05). Conclusions: The Chinese version of the PAHCQ is a feasible, effective, and reliable tool that can be used to evaluate Chinese patients' perception of health system accessibility.

Shared Decision-Making and Cardiovascular Health: A Scientific Statement From the American Heart Association

Shared decision-making is increasingly embraced in health care and recommended in cardiovascular guidelines. Patient involvement in health care decisions, patient-clinician communication, and models of patient-centered care are critical to improve health outcomes and to promote equity, but formal models and evaluation in cardiovascular care are nascent. Shared decision-making promotes equity by involving clinicians and patients, sharing the best available evidence, and recognizing the needs, values, and experiences of individuals and their families when faced with the task of making decisions. Broad endorsement of shared decision-making as a critical component of high-quality, value-based care has raised our awareness, although uptake in clinical practice remains suboptimal for a range of patient, clinician, and system issues. Strategies effective in promoting shared decision-making include educating clinicians on communication techniques, engaging multidisciplinary medical teams, incorporating trained decision coaches, and using tools (ie, patient decision aids) at appropriate literacy and numeracy levels to support patients in their cardiovascular decisions. This scientific statement shines a light on the limited but growing body of evidence of the impact of shared decision-making on cardiovascular outcomes and the potential of shared decision-making as a driver of health equity so that everyone has just opportunities. Multilevel solutions must align to address challenges in policies and reimbursement, system-level leadership and infrastructure, clinician training, access to decision aids, and patient engagement to fully support patients and clinicians to engage in the shared decision-making process and to drive equity and improvement in cardiovascular outcomes.

'Snapshot' cohort study design across multi-site research settings: challenges, strategies, and solutions

Multi-site research studies redefine cohort studies by simultaneously providing a cross-sectional snapshot of patients and monitoring them over time, to evaluate outcomes. However, careful design is crucial to minimize potential biases, such as seasonal variations, that may arise during the study period. Addressing snapshot study challenges requires strategic solutions: implementing multi-stage sampling for representativeness, providing rigorous data collection training, using translation techniques and content validation for cultural and linguistic appropriateness, streamlining ethical approval processes, and applying comprehensive data management for follow-up and missing data. These strategies can optimize the efficacy and ethicality of snapshot studies.

Hospital-service use in the last year of life by patients aged ⩾60 years who died of heart failure or cardiomyopathy: A retrospective linked data study

BACKGROUND

Understanding patterns of health care use in the last year of life is critical in health services planning.

AIM

To describe hospital-based service and palliative care use in hospital in the year preceding death for patients who died of heart failure or cardiomyopathy in Queensland from 2008 to 2018 and had at least one hospitalisation in the year preceding death.

DESIGN

A retrospective data linkage study was conducted using administrative health data relating to hospitalisations, emergency department visits and deaths.

PARTICIPANTS AND SETTING

Participants included were those aged ⩾60 years, had a hospitalisation in their last year of life and died of heart failure or cardiomyopathy in Queensland, Australia.

RESULTS

Of the 4697 participants, there were 25,583 hospital admissions. Three quarters (n = 3420, 73%) of participants were aged ⩾80 years and over half died in hospital (n = 2886, 61%). The median number of hospital admissions in the last year of life was 3 (interquartile range [IQR] 2-5). The care type was recorded as 'acute' for 89% (n = 22,729) of hospital admissions, and few (n = 853, 3%) hospital admissions had a care type recorded as 'palliative.' Of the 4697 participants, 3458 had emergency department visit(s), presenting 10,330 times collectively.

CONCLUSION

In this study, patients who died of heart failure or cardiomyopathy were predominantly aged ⩾80 years and over half died in hospital. These patients experienced repeat acute hospitalisations in the year preceding death. Improving timely access to palliative care services in the outpatient or community setting is needed for patients with heart failure.

Global impacts of COVID-19 on lifestyles and health and preparation preferences: An international survey of 30 countries

Background

The health area being greatest impacted by coronavirus disease 2019 (COVID-19) and residents' perspective to better prepare for future pandemic remain unknown. We aimed to assess and make cross-country and cross-region comparisons of the global impacts of COVID-19 and preparation preferences of pandemic.

Methods

We recruited adults in 30 countries covering all World Health Organization (WHO) regions from July 2020 to August 2021. 5 Likert-point scales were used to measure their perceived change in 32 aspects due to COVID-19 (-2 = substantially reduced to 2 = substantially increased) and perceived importance of 13 preparations (1 = not important to 5 = extremely important). Samples were stratified by age and gender in the corresponding countries. Multidimensional preference analysis displays disparities between 30 countries, WHO regions, economic development levels, and COVID-19 severity levels.

Results

16 512 adults participated, with 10 351 females. Among 32 aspects of impact, the most affected were having a meal at home (mean (m) = 0.84, standard error (SE) = 0.01), cooking at home (m = 0.78, SE = 0.01), social activities (m = -0.68, SE = 0.01), duration of screen time (m = 0.67, SE = 0.01), and duration of sitting (m = 0.59, SE = 0.01). Alcohol (m = -0.36, SE = 0.01) and tobacco (m = -0.38, SE = 0.01) consumption declined moderately. Among 13 preparations, respondents rated medicine delivery (m = 3.50, SE = 0.01), getting prescribed medicine in a hospital visit / follow-up in a community pharmacy (m = 3.37, SE = 0.01), and online shopping (m = 3.33, SE = 0.02) as the most important. The multidimensional preference analysis showed the European Region, Region of the Americas, Western Pacific Region and countries with a high-income level or medium to high COVID-19 severity were more adversely impacted on sitting and screen time duration and social activities, whereas other regions and countries experienced more cooking and eating at home. Countries with a high-income level or medium to high COVID-19 severity reported higher perceived mental burden and emotional distress. Except for low- and lower-middle-income countries, medicine delivery was always prioritised.

Conclusions

Global increasing sitting and screen time and limiting social activities deserve as much attention as mental health. Besides, the pandemic has ushered in a notable enhancement in lifestyle of home cooking and eating, while simultaneously reducing the consumption of tobacco and alcohol. A health care system and technological infrastructure that facilitate medicine delivery, medicine prescription, and online shopping are priorities for coping with future pandemics.

Practices, beliefs, and attitudes of clinicians in prescribing direct oral anticoagulants for obese adults with atrial fibrillation: a qualitative study

BACKGROUND

Atrial fibrillation (AF) and obesity affect over 60 and 650 million people, respectively.

AIM

This study aimed to explore clinician practices, beliefs, and attitudes towards the use of direct oral anticoagulants (DOACs) in obese adults (BMI ≥ 30 kg/m2) with AF.

METHOD

Semi-structured interviews via video conference were conducted with multidisciplinary clinicians from across Australia, with expertise in DOAC use in adults with AF. Clinicians were invited to participate using purposive and snowball sampling techniques. Data were analysed in NVIVO using thematic analysis.

RESULTS

Fifteen clinicians including cardiologists (n = 5), hospital and academic pharmacists (n = 5), general practitioners (n = 2), a haematologist, a neurologist and a clinical pharmacologist participated. Interviews were on average 31 ± 9 min. Key themes identified were: Health system factors in decision-making Disparities between rural and metropolitan geographic areas, availability of health services, and time limitations for in-patient decision-making, were described; Condition-related factors in decision-making Clinicians questioned the significance of obesity as part of decision-making due to the practical limitations of dose modification, and the rarity of the extremely obese cohort; Decision-making in the context of uncertainty Clinicians reported limited availability, reliability and awareness of primary evidence including limited guidance from clinical guidelines for DOAC use in obesity.

CONCLUSION

This study highlights the complexity of decision-making for clinicians, due to the limited availability, reliability and awareness of evidence, the intrinsic complexity of the obese cohort and limited guidance from clinical guidelines. This highlights the urgent need for contemporary research to improve the quality of evidence to guide informed shared decision-making.

Palliative Care Needs of Physically Frail Community-Dwelling Older Adults With Heart Failure

CONTEXT

Physical frailty is emerging as a potential "trigger" for palliative care (PC) consultation, but the PC needs of physically frail persons with heart failure (HF) in the outpatient setting have not been well described.

OBJECTIVES

This study describes the PC needs of community dwelling, physically frail persons with HF.

METHODS

We included persons with HF ≥50 years old who experienced ≥1 hospitalization in the prior year and excluded those with moderate/severe cognitive impairment, hospice patients, or non-English speaking persons. Measures included the FRAIL scale (0-5: 0 = robust, 1-2 = prefrail, 3-5 = frail) and the Integrated Palliative Outcome Scale (IPOS) (17 items, score 0-68; higher score = higher PC needs). Multiple linear regression tested the association between frailty group and palliative care needs.

RESULTS

Participants (N = 286) had a mean age of 68 (range 50-92) were majority male (63%) and White (68%) and averaged two hospitalizations annually. Most were physically frail (44%) or prefrail (41%). Mean PC needs (IPOS) score was 19.7 (range 0-58). On average, participants reported 5.86 (SD 4.28) PC needs affecting them moderately, severely, or overwhelmingly in the last week. Patient-perceived family/friend anxiety (58%) weakness/lack of energy (58%), and shortness of breath (47%) were the most prevalent needs. Frail participants had higher mean PC needs score (26) than prefrail (16, P < 0.001) or robust participants (11, P < 0.001). Frail participants experienced an average of 8.32 (SD 3.72) moderate/severe/overwhelming needs compared to prefrail (4.56, SD 3.77) and robust (2.39, SD 2.91) participants (P < 0.001). Frail participants reported higher prevalence of weakness/lack of energy (83%), shortness of breath (66%), and family/friend anxiety (69%) than prefrail (48%, 39%, 54%) or robust (13%, 14%, 35%) participants (P < 0.001).

CONCLUSION

Physically frail people with HF have higher unmet PC needs than those who are nonfrail. Implementing PC needs and frailty assessments may help identify vulnerable patients with unmet needs requiring further assessment and follow-up.

The Context of Caregiving in Heart Failure: A Dyadic, Mixed Methods Analysis

BACKGROUND

Caregiving for persons with heart failure (HF) varies based on the individual, family, and home contexts of the dyad, yet the dyadic context of HF caregiving is poorly understood.

OBJECTIVE

The aim of this study was to explore dyadic perspectives on the context of caregiving for persons with HF.

METHODS

Family caregivers and persons with HF completed surveys and semistructured interviews. Investigators also photographed caregiving areas to complement home environment data. Descriptive qualitative analysis resulted in 7 contextual domains, and each domain was rated as strength, need, or neutral. We grouped dyads by number of challenging domains of context, categorizing dyads as high (≥3 domains), moderate (1-2 domains), or minimal (0 domains) needs. Quantitative instruments included the 36-item Short Form Health Survey, ENRICHD Social Support, HF Symptom Severity, and Zarit Burden Interview. We applied the average score of each quantitative measure to the groups derived from the qualitative analysis to integrate data in a joint display.

RESULTS

The most common strength was the dyadic relationship, and the most challenging domain was caregiving intensity. Every dyad had at least 2 domains of strengths. Of 12 dyads, high-needs dyads (n = 3) had the worst average score for 7 of 10 instruments including caregiver and patient factors. The moderate-needs dyads (n = 6) experienced the lowest caregiver social support and mental health, and the highest burden.

CONCLUSION

Strengths and needs were evident in all patient-caregiver dyads with important distinctions in levels of need based on assessment of multiple contextual domains. Comprehensive dyadic and home assessments may improve understanding of unmet needs and improve intervention tailoring.

Community empowerment: A concept analysis

AIM

To report an analysis of the concept of community empowerment.

DESIGN

Concept analysis.

DATA SOURCES

Literature published in the CINAHL, PubMed, Scopus and Medline electronic databases from 2016 to 2022 were systematically searched from 30 July to 1 October 2022.

METHOD

The amended guideline from Walker and Avant's approach (2011) to concept analysis was performed in nine stages: choosing a concept, determining the purpose of analysis, identifying definitions of the concept, defining attributes, identifying a model case, identifying antecedents, identifying consequences, defining empirical referents and applying the concept to nursing practice.

RESULTS

Community empowerment is a fundamental idea in health promotion that may assist communities in defining priorities, making choices, developing strategies and executing them to improve health and minimize inequalities in health. Community empowerment is an effective tool that advanced practice nurses (APNs) may employ to eliminate health inequities and promote community health.

CONCLUSION

This concept analysis is one step towards broadening nurses' understanding of one of the ideas of health promotion. Additionally, the concept of community empowerment represents an opportunity for additional research in nursing that is applicable to communities.

IMPACT

Community empowerment has served as a guiding paradigm for both theory and practice in health promotion. Also, it is recognized that social, economic and environmental elements have a direct effect on health status. However, community empowerment research in advanced nursing practices is limited. This paper will guide future nursing research on community empowerment that goes beyond involvement and engagement, for this is an effective strategy APNs can use to address health disparities and improve community health.

Treatment patterns and out-of-hospital healthcare resource utilisation by patients with advanced cancer living with pain: An analysis from the Stop Cancer PAIN trial

BACKGROUND

About 70% of patients with advanced cancer experience pain. Few studies have investigated the use of healthcare in this population and the relationship between pain intensity and costs.

METHODS

Adults with advanced cancer and scored worst pain ≥ 2/10 on a numeric rating scale (NRS) were recruited from 6 Australian oncology/palliative care outpatient services to the Stop Cancer PAIN trial (08/15-06/19). Out-of-hospital, publicly funded services, prescriptions and costs were estimated for the three months before pain screening. Descriptive statistics summarize the clinico-demographic variables, health services and costs, treatments and pain scores. Relationships with costs were explored using Spearman correlations, Mann-Whitney U and Kruskal-Wallis tests, and a gamma log-link generalized linear model.

RESULTS

Overall, 212 participants had median worst pain scores of five (inter-quartile range 4). The most frequently prescribed medications were opioids (60.1%) and peptic ulcer/gastro-oesophageal reflux disease (GORD) drugs (51.6%). The total average healthcare cost in the three months before the census date was A$6,742 (95% CI $5,637, $7,847), approximately $27,000 annually. Men had higher mean healthcare costs than women, adjusting for age, cancer type and pain levels (men $7,872, women $4,493, p<0.01) and higher expenditure on prescriptions (men $5,559, women $2,034, p<0.01).

CONCLUSIONS

In this population with pain and cancer, there was no clear relationship between healthcare costs and pain severity. These treatment patterns requiring further exploration including the prevalence of peptic ulcer/GORD drugs, and lipid lowering agents and the higher healthcare costs for men.

Using rapid response system trigger clusters to characterize patterns of clinical deterioration among hospitalized adult patients

Background

Many rapid response system (RRS) events are activated using multiple triggers. However, the patterns in which RRS triggers co-occur to activate the medical emergency team (MET) to respond to RRS events is unknown. The purpose of this study was to identify and describe the patterns (RRS trigger clusters) in which RRS triggers co-occur when used to activate the MET and determine the association of these clusters with outcomes using a sample of hospitalized adult patients.

Methods

RRS events among adult patients from January 2015 to December 2019 in the Get With The Guidelines- Resuscitation registry's MET module were examined (n=134,406). A combination of cluster analyses methods was performed to group patients into RRS trigger clusters based on the triggers used to activate their RRS events. Pearson's chi-squared and ANOVA tests were used to examine differences in patient characteristics across RRS trigger clusters. Multilevel logistic regression was used to examine the associations between RRS trigger clusters and outcomes following RRS events.

Results

Six RRS trigger clusters were identified in the study sample. The RRS triggers that predominantly identified each cluster were as follows: tachypnea, new onset difficulty in breathing, and decreased oxygen saturation (Cluster 1); tachypnea, decreased oxygen saturation, and staff concern (Cluster 2); respiratory depression, decreased oxygen saturation, and mental status changes (Cluster 3); tachycardia and staff concern (Cluster 4); mental status changes (Cluster 5); hypotension and staff concern (Cluster 6). Significant differences in patient characteristics were observed across RRS trigger clusters. Patients in Clusters 3 and 6 were associated with an increased likelihood of in-hospital cardiac arrest (IHCA [p<0.01]), while Cluster 4 was associated with a decreased likelihood of IHCA (p<0.01). All clusters were associated with an increased risk of mortality (p<0.01).

Conclusions

We discovered six novel RRS trigger clusters with differing relationships to adverse patient outcomes following RRS events. RRS trigger clusters may prove crucial in clarifying the associations between RRS events and adverse outcomes and may aid in clinician decision-making during RRS events.

Patterns of Health-Related Quality of Life among Stroke Survivors: A Longitudinal Study

Six months poststroke is critical for optimizing stroke survivors' recovery and improving their health-related quality of life (HRQoL). Understanding HRQoL profiles in specific domains can provide a more typical plan for stroke survivors. This pilot study aimed to explore the HRQoL patterns among 39 stroke survivors within 6 months following diagnosis. The results revealed that there were four patterns based on HRQoL domains. Pattern 1: energy, family role, mobility, self-care, social role, and work/productivity domains likely to improve; Pattern 2: language and vision domains likely to improve and be stable; Pattern 3: thinking and upper extremity function domains likely to worsen and improve later; and Pattern 4: mood and personality domains likely to worsen and be constant. Health care providers can apply these results by continuing to assess and provide care to stroke survivors focusing on functional status, cognitive status, and depression over time. Further study should explore the factors predicting HRQoL.

"Living like an empty gas tank with a leak": Mixed methods study on post-acute sequelae of COVID-19

BACKGROUND

The burden and presentation of post-acute sequela of SARS-CoV-2 infection (PASC) are a developing major public health concern.

OBJECTIVES

To characterize the burden of PASC in community-dwelling individuals and understand the experiences of people living with PASC.

METHODS

This mixed-methods study of COVID-19 positive community-dwelling persons involved surveys and in-depth interviews. Main outcome was self-report of possible PASC symptoms 3 weeks or longer after positive COVID-19 test. In-depth interviews were guided by a semi-structured interview guide with open-ended questions and probes based on emerging literature on PASC and the impact of COVID-19.

RESULTS

With a survey response rate of 70%, 442 participants were included in this analysis, mean (SD) age 45.4 (16.2) years, 71% female, 12% Black/African American. Compared to those with no PASC symptoms, persons who reported PASC symptoms were more likely to be older (mean age: 46.5 vs. 42; p = 0.013), female (74.3% vs. 61.2%; p = 0.010), to have pre-existing conditions (49.6% vs. 34%; p = 0.005), and to have been hospitalized for COVID-19 (14.2% vs. 2.9%; p = 0.002). About 30% of the participants experienced severe fatigue; the proportion of persons reporting severe fatigue was 7-fold greater in those with PASC symptoms (Adjusted Prevalence Ratio [aPR] 6.73, 95%CI: 2.80-16.18). Persons with PASC symptoms were more likely to report poor quality of life (16% vs. 5%, p<0.001) and worse mental health functioning (Mean difference: -1.87 95%CI: -2.38, -1.37, p<0.001). Themes from in-depth interviews revealed PASC was experienced as debilitating.

CONCLUSIONS

In this study, the prevalence of PASC among community-dwelling adults was substantial. Participants reported considerable coping difficulties, restrictions in everyday activities, invisibility of symptoms and experiences, and impediments to getting and receiving PASC care.

Methods and operational aspects of human-centred design into research processes for individuals with multiple chronic conditions: A survey study

AIM

To examine ways in which human-centred design was integrated into a nursing school's research processes involving individuals with multiple chronic conditions.

DESIGN

Cross-sectional survey study.

METHODS

Three surveys were sent out, with surveys 1 and 2 involving faculty who had worked closely with design strategists and survey 3 as a school-wide survey eliciting experience with human-centred design, respectively.

RESULTS

Survey respondents (n = 7 for surveys 1 and 2 and n = 36 for survey 3) had no or minimal experience with human-centred design. Faculty respondents indicated it helped engaging various stakeholders, particularly in intervention development. Key lessons learned included: (1) the importance of designer involvement from study conception, (2) distinguishing a design strategist's skillset from strictly visual design, (3) challenges during the ethical review processes, and (4) sustainability of resources. The dynamic approach of human-centred design has benefited our efforts to advance the science of caring for individuals with multiple chronic conditions.

Nursing and human-computer interaction in healthcare robots for older people: An integrative review

Objectives

This study examined the published works related to healthcare robotics for older people using the attributes of health, nursing, and the human-computer interaction framework.

Design

An integrative literature review.

Methods

A search strategy captured 55 eligible articles from databases (CINAHL, Embase, IEEE Xplore, and PubMed) and hand-searching approaches. Bibliometric and content analyses grounded on the health and nursing attributes and human-computer interaction framework were performed using MAXQDA. Finally, results were verified using critical friend feedback by a second reviewer.

Results

Most articles were from multiple authorship, published in non-nursing journals, and originating from developed economies. They primarily focused on applying healthcare robots in practice settings, physical health, and communication tasks. Using the human-computer interaction framework, it was found that older adults frequently served as the primary users while nurses, healthcare providers, and researchers functioned as secondary users and operators. Research articles focused on the usability, functionality, and acceptability of robotic systems. At the same time, theoretical papers explored the frameworks and the value of empathy and emotion in robots, human-computer interaction and nursing models and theories supporting healthcare practice, and gerontechnology. Current robotic systems are less anthropomorphic, operated through real-time direct and supervisory inputs, and mainly equipped with visual and auditory sensors and actuators with limited capability in performing health assessments.

Conclusion

Results communicate the need for technological competency among nurses, advancements in increasing healthcare robot humanness, and the importance of conscientious efforts from an interdisciplinary research team in improving robotic system usability and utility for the care of older adults.

Multi-level correlates of received social support among heart transplant recipients in the international BRIGHT Study: a secondary analysis

AIMS

Social support is critical in follow-up of patients after heart transplant (HTx) and positively influences well-being and clinical outcomes such as medication adherence. The purpose of this study was to (i) explore received social support variation (emotional and practical) in HTx recipients at country and centre level and (ii) to assess multi-level correlates.

METHODS AND RESULTS

Secondary data analysis of the multi-level cross-sectional BRIGHT study was conducted in 36 HTx centres in 11 countries. Received social support related to medication adherence was measured with emotional and practical sub-scales. The Conceptual Model of Social Networks and Health guided selection of patient, micro (interpersonal and psychosocial), meso (HTx centre) and macro-level (country health system) factors. Descriptive statistics, intraclass correlations, and sequential multiple ordinal mixed logistic regression analysis were used. A total of 1379 adult HTx recipients were included. Patient level correlates (female sex, living alone, and fewer depressive symptoms) and micro-level correlates (higher level of chronic disease management and trust in the healthcare team) were associated with better emotional social support. Similarly, patient level (living alone, younger age, and male sex), micro-level and meso-level (patient and clinician-rated higher level of chronic disease management) were associated with better practical social support. Social support varied at country and centre levels for emotional and practical dimensions.

CONCLUSIONS

Social support in HTx recipients varies by country, centre, and was associated with multi-level correlates. Qualitative and longitudinal studies are needed to understand influencing factors of social support for intervention development, improvement of social support, and clinical outcomes.

Noninvasive cardiac output monitor to quantify hydration status in ischemic stroke patients: A feasibility study

BACKGROUND

Individuals who are dehydrated, volume contracted or both at the time of hospitalization for acute ischemic stroke have worse clinical outcomes than do individuals with optimal volume status. Currently, there is no gold standard method for measuring hydration status, except indirect markers of a volume contracted state (VCS) including elevated blood urea nitrogen (BUN)/creatinine ratio. We sought to test the feasibility and acceptability of a non-invasive cardiac output monitor (NICOM) for the measurement of hydration status in a group of hospitalized ischemic stroke patients, and explore the relationship with a common indirect laboratory-based measure of VCS.

METHODS

We performed a prospective observational feasibility study of hospitalized acute ischemic stroke patients. We collected hemodynamic parameters using the NICOM device before and after fluid auto-bolus via passive leg raise and BUN/creatinine ratio. Successful acquisition of relevant hemodynamic data was the primary objective of this study. We explored agreement between the NICOM results and BUN/creatinine ratio using Cohen's kappa statistic.

RESULTS

Thirty patients hospitalized with acute ischemic stroke were enrolled. We found that 29/30 patients tolerated assessment with NICOM. Hemodynamic data were collected in all 30 patients. Data capture took an average of 10 min(SD ± 112 s). Agreement between NICOM and BUN/creatinine ratio was 70%; (expected agreement 51%; kappa 0.38). Agreement was stronger in the cohort without history of diabetes (81% agreement, kappa 0.61).

CONCLUSIONS

NICOM assessment was feasible in hospitalized stroke patients. The identification of an objective, real-time measure of hydration status would be clinically useful, and could allow precise, goal-directed care.

Expedited upskilling of intermediate care nurses to provide critical care during the COVID-19 pandemic

AIM

Describe the strategy, efficacy and preferred mechanisms of training used to rapidly upskill intermediate care nursing staff to provide critical care during the COVID-19 pandemic.

DESIGN

Descriptive study.

METHODS

The strategy used from March through December 2020 to upskill nurses in an intermediate care unit to administer critical care upon rapid conversion of the intermediate care unit to an intensive care unit for coronavirus disease 2019 is described. Training and education included paired staffing models, interdisciplinary education, skills days and self-directed learning. Nurses engaged in this upskilling process were surveyed to evaluate their confidence in new critical care competencies and educational preferences.

RESULTS

Of 38 intermediate care nurses, 35 completed training and began independent intensive care practice. Nursing confidence in critical care competencies increased steadily. Nurses demonstrated the greatest preference for peer education models, particularly those incorporating the hospital's pre-existing medical intensive care nurses.

Comparison of six frailty instruments in adults with heart failure: a prospective cohort pilot study

Aim

To compare the frailty prevalence and predictive performance of six frailty instruments in adults with heart failure and determine feasibility of study methods.

Methods and Results

Prospective cohort pilot study. Adults aged 18 years or older with a confirmed diagnosis of heart failure in Sydney, New South Wales, Australia. The Frailty Phenotype; the Survey of Health, Ageing and Retirement in Europe Frailty Instrument (SHARE-FI); St Vincent’s Frailty instrument; St Vincent’s Frailty instrument plus cognition and mood; The Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) scale; and the Deficit Accumulation Index were compared. Multiple logistic regression was used to develop six frailty instrument models to evaluate the association between each frailty instrument and composite all-cause rehospitalisation and mortality at 12 months

One hundred and thirty-one patients were included with a mean age of 54 (± 14[SD]). Frailty prevalence ranged from 33-81%. All instruments except one (the FRAIL scale) appeared to signal an increased odds of rehospitalisation and/or mortality, yet these results were non-significant. The six frailty instrument models displayed sensitivity between 88-92% and C-statistic values of 0.71-0.73, suggesting satisfactory discrimination.

Conclusions

The prevalence of frailty varied across six frailty instruments yet was in the higher range despite a ‘younger’ heart failure cohort. Further research is required to confirm the psychometric properties of these instruments for routine clinical use in an adequately powered and more diverse heart failure cohort.

Cardiac postacute sequelae symptoms of SARS-CoV-2 in community-dwelling adults: cross-sectional study

Objective

To examine risk factors for cardiac-related postacute sequelae of SARS-CoV-2 infection (PASC) in community-dwelling adults after acute COVID-19 infection.

Methods

We performed a cross-sectional analysis among adults who tested positive for COVID-19. Outcomes were self-reported cardiac-related PASC. We conducted stepwise multivariable logistic regression to assess association between the risk factors (existing cardiovascular disease (CVD), pre-existing conditions, days since positive test, COVID-19 hospitalisation, age, sex, education, income) and cardiac-related PASC.

Results

In a sample of 442 persons, mean (SD) age was 45.4 (16.2) years, 71% were women, 13% were black, 46% had pre-existing conditions, 23% had cardiovascular (CV) risk factors and 4% had CVD. Prevalence of cardiac PASC was 43% and newly diagnosed cardiac conditions were 27%. The odds for cardiac-related PASC were higher among persons with underlying pre-existing conditions (adjusted OR (aOR): 2.00, 95% CI: 1.28 to 3.10) and among those who were hospitalised (aOR: 3.03, 95% CI: 1.58 to 5.83).

Conclusions

More than a third of persons with COVID-19 reported cardiac-related PASC symptoms. Underlying CVD, pre-existing diseases, age and COVID-19 hospitalisation are possible risk factors for cardiac-related PASC symptoms. COVID-19 may exacerbate CV risk factors and increase risk of complications.

Low lamin A levels enhance confined cell migration and metastatic capacity in breast cancer

Aberrations in nuclear size and shape are commonly used to identify cancerous tissue. However, it remains unclear whether the disturbed nuclear structure directly contributes to the cancer pathology or is merely a consequence of other events occurring during tumorigenesis. Here, we show that highly invasive and proliferative breast cancer cells frequently exhibit Akt-driven lower expression of the nuclear envelope proteins lamin A/C, leading to increased nuclear deformability that permits enhanced cell migration through confined environments that mimic interstitial spaces encountered during metastasis. Importantly, increasing lamin A/C expression in highly invasive breast cancer cells reflected gene expression changes characteristic of human breast tumors with higher LMNA expression, and specifically affected pathways related to cell-ECM interactions, cell metabolism, and PI3K/Akt signaling. Further supporting an important role of lamins in breast cancer metastasis, analysis of lamin levels in human breast tumors revealed a significant association between lower lamin A levels, Akt signaling, and decreased disease-free survival. These findings suggest that downregulation of lamin A/C in breast cancer cells may influence both cellular physical properties and biochemical signaling to promote metastatic progression.
