RESUMEN

BACKGROUND: Unscheduled care is used increasingly during the last year of life by people known to have significant palliative care needs. AIM: To document the frequency and patterns of use of unscheduled healthcare by people in their last year of life and understand the experiences and perspectives of patients, families and professionals about accessing unscheduled care out-of-hours. DESIGN: A mixed methods, multi-stage study integrating a retrospective cohort analysis of unscheduled healthcare service use in the last year of life for all people dying in Scotland in 2016 with qualitative data from three regions involving service users, bereaved carers and general practitioners. SETTING: Three contrasting Scottish Health Board regions and national datasets for the whole of Scotland. RESULTS: People who died in Scotland in 2016 (n = 56,407) had 472,360 unscheduled contacts with one of five services: telephone advice, primary care, ambulance service, emergency department and emergency hospital admission. These formed 206,841 individual continuous unscheduled care pathways: 65% starting out-of-hours. When accessing healthcare out-of-hours, patients and carers prioritised safety and a timely response. Their choice of which service to contact was informed by perceptions and previous experiences of potential delays and whether the outcome might be hospital admission. Professionals found it difficult to practice palliative care in a crisis unless the patient had previously been identified. CONCLUSION: Strengthening unscheduled care in the community, together with patient and public information about how to access these services could prevent hospital admissions of low benefit and enhance community support for people living with advanced illness.

RESUMEN

WHAT IS KNOWN AND OBJECTIVE: Cardiovascular disease is of increasing concern in patients living with HIV. The significant advancement in antiretroviral treatment has ensured that patients are now succumbing to traditional diseases of ageing. First generation antiretroviral therapy caused multiple side effects including significant dyslipidaemia. Despite the advancement and improving safety profile of treatment concerns remain about antiretroviral induced dyslipidaemia. We sought to investigate the real-world effect on lipids in patients switching to a Bictegravir based regime. METHODS: We conducted a retrospective analysis in patients switching therapy to Biktarvy at the Royal Liverpool University Hospital. Data was collected from the HIV database that is established for clinical use, as an electronic patient record, and audit purposes. Lipid data was cross checked with the Trust electronic reporting system. Participants were included if they were HIV-positive, >18 years and had switched to Biktarvy Patients were also required to have a lipid profile available 52 weeks prior to switching and 100 weeks post switching. Summary statistic were calculated and multiple regressions models were constructed to assess the independent predictors of lipid change. We also performed one way analysis of covariance (ANCOVA) to assess the impact of switching therapy on each quartile of the baseline lipid panel. RESULTS AND DISCUSSION: There were 135 patients included in the analysis with a mean age of 47. The majority of the population were male (80%). At a mean follow up of 42 weeks post switch there was no significant difference in total cholesterol (p = 0.64), triglyceride (p = 0.64) or high density lipoprotein (HDL) cholesterol (p = 0.08). In the regression analysis the highest quartile of baseline total cholesterol and triglyceride were independently associated with improvement in lipid markers. Switching from protease inhibitor therapy was also significantly associated with improvement in triglyceride. In addition, the ANCVOA demonstrated that the highest quartiles of total cholesterol, triglyceride and the lowest quartile of HDL were associated with significant improvement in lipid markers after switching to Bictegravir. WHAT IS NEW AND CONCLUSION: We demonstrated that patients with the most adverse lipid profiles at baseline had significant improvements in lipid profiles. In addition, patient switching away from protease inhibitor therapy also had significant improvements in triglyceride.

RESUMEN

Small businesses are critical to community recovery from disasters. However, factors that affect outcomes (such as planning, information needs, and responses to warnings) are understudied. To address the research record's focus on policy that favours disaster mitigation rather than response, this project applied a two-phased, mixed-method approach. The first study comprised interviews with businesses to elucidate disaster planning approaches, knowledge and information needs, and current warning system adequacy. It revealed opportunities to build knowledge and add business-specific content to agency-issued warnings. The second study used an online survey to examine how disaster knowledge, planning, and experience are related to existing bushfire warnings and those modified with business-relevant content. The findings show that planning is associated with experience and knowledge but not with business-related protective action intentions. Modified messages were perceived as more effective and resulted in greater action intentions among those with bushfire experience. In sum, the paper highlights implications for small business-oriented disaster risk communication.

RESUMEN

A prominent hypothesis regarding the pathophysiology of autism is that an increase in the balance between neural excitation and inhibition results in an increase in neural responses. However, previous reports of population-level response magnitude in individuals with autism have been inconsistent. Critically, network interactions have not been considered in previous neuroimaging studies of excitation and inhibition imbalance in autism. In particular, a defining characteristic of cortical organization is its hierarchical and interactive structure; sensory and cognitive systems are comprised of networks where later stages inherit and build upon the processing of earlier input stages, and also influence and shape earlier stages by top-down modulation. Here we used the well established connections of the human visual system to examine response magnitudes in a higher-order motion processing region [middle temporal area (MT+)] and its primary input region (V1). Simple visual stimuli were presented to adult individuals with autism spectrum disorders (ASD; n = 24, mean age 23 years, 8 females) and neurotypical controls (n = 24, mean age 22, 8 females) during fMRI scanning. We discovered a strong dissociation of fMRI response magnitude between region MT+ and V1 in individuals with ASD: individuals with high MT+ responses had attenuated V1 responses. The magnitude of MT+ amplification and of V1 attenuation was associated with autism severity, appeared to result from amplified suppressive feedback from MT+ to V1, and was not present in neurotypical controls. Our results reveal the potential role of altered hierarchical network interactions in the pathophysiology of ASD.SIGNIFICANCE STATEMENT An imbalance between neural excitation and inhibition, resulting in increased neural responses, has been suggested as a pathophysiological pathway to autism, but direct evidence from humans is lacking. In the current study we consider the role of interactions between stages of sensory processing when testing increased neural responses in individuals with autism. We used the well known hierarchical structure of the visual motion pathway to demonstrate dissociation in the fMRI response magnitude between adjacent stages of processing in autism: responses are attenuated in a primary visual area but amplified in a subsequent higher-order area. This response dissociation appears to rely on enhanced suppressive feedback between regions and reveals a previously unknown cortical network alteration in autism.

RESUMEN

BACKGROUND: Due to the uncertain disease trajectory and variable rate of progression in chronic obstructive pulmonary disease (COPD), health care professionals (HCPs) are challenged in explaining what the future may hold for patients compared to those with lung cancer (LC). Support and communication of timely information can significantly improve health outcomes. OBJECTIVE: This study sought to identify factors that impact communication and support and recommend ways to improve patients' understanding of living with life-threatening illness. METHODS: Semi-structured interviews with patients with LC (n = 22) and advanced COPD (n = 18), their informal carers (21 LC and 18 COPD) and HCPs (n = 51). Patients were recruited from primary and secondary care in the East of England, UK, during 2010-12. RESULTS: Directness and clarity characterized communication in LC, whereas uncertainty and limited explanations predominated in COPD. Discussions on how the disease might impact on decisions and preferences to be made in the future were less common in COPD. Information for LC patients was mainly from hospital clinicians and any information for COPD patients mainly from primary care clinicians. CONCLUSIONS: The experience of COPD patients could be improved by professionals soon after diagnosis explaining to them the typical pattern of decline in COPD, highlighting the inherent uncertainties about when exacerbations and death may occur. This conversation should lead to planning for the different challenges that the patient and informal carer recognize as most important to them. This contrasts with the 'breaking bad news' conversation that oncologists are highly trained to deliver.


People living with lung cancer (LC) or chronic obstructive pulmonary disease (COPD) have poor health-related quality of life. However, more people with LC receive holistic palliative care (which involves supportive advance care planning) than those with COPD. We interviewed patients with LC or COPD, their informal carers (family/friends who support them) and health care professionals (HCPs) about their experiences and our findings confirmed this: HCPs said the uncertainty of COPD prognosis made starting advance care planning conversations challenging. The level of uncertainty and unpredictability is very different in LC and COPD: the cancer diagnosis is made at a single point in time with mortality immediately on the agenda, while COPD is a chronic condition that develops over many years. We urge clinicians to share this uncertainty with patients and to try to explain and communicate it sooner than later. These conversations should also continue as a recognized part of ongoing care so that COPD patients can benefit from understanding the uncertainties they are dealing and living with. LC and COPD should be approached differently to meet patients' condition-specific needs in order that the existing disparity in holistic care can be remedied.

RESUMEN

BACKGROUND: Specialist palliative care (SPC) providers tend to use the term 'complex' to refer to the needs of patients who require SPC. However, little is known about complex needs on first referral to a SPC service. We examined which needs are present and sought the perspectives of healthcare professionals on the complexity of need on referral to a hospice service. METHODS: Multi-site sequential explanatory mixed method study consisting of a case-note review and focus groups with healthcare professionals in four UK hospices. RESULTS: Documentation relating to 239 new patient referrals to hospice was reviewed; and focus groups involving 22 healthcare professionals conducted. Most patients had two or more needs documented on referral (96%); and needs were recorded across two or more domains for 62%. Physical needs were recorded for 91% of patients; psychological needs were recorded for 59%. Spiritual needs were rarely documented. Referral forms were considered limited for capturing complex needs. Referrals were perceived to be influenced by the experience and confidence of the referrer and the local resource available to meet palliative care needs directly. CONCLUSIONS: Complexity was hard to detail or to objectively define on referral documentation alone. It appeared to be a term used to describe patients whom primary or secondary care providers felt needed SPC knowledge or support to meet their needs. Hospices need to provide greater clarity regarding who should be referred, when and for what purpose. Education and training in palliative care for primary care nurses and doctors and hospital clinicians could reduce the need for referral and help ensure that hospices are available to those most in need of SPC input.

RESUMEN

BACKGROUND: Although transcatheter aortic valve implantation (TAVI) has become the standard treatment for severe aortic stenosis in high-risk patients in Australia, there is still limited data on long term survival. METHODS: All patients undergoing TAVI at a single tertiary institution between September 2009 and December 2015 were included. The primary outcome was survival, by linkage of patients with the National Death Index of the Australian Institute of Health and Welfare. Post-procedure data and echocardiographic measurements were retrospectively analysed for all patients. RESULTS: A total of 186 patients were included. It was a high-risk patient population (mean EuroSCORE 31.5±20.5, mean age 83.0±8.2 years). Valve prostheses used were Edwards SAPIEN (ES) (Edwards, Irvine, CA, USA) in 16.1%, Edwards SAPIEN XT (ESXT) in 74.2%, and Medtronic CoreValve (MCV) (Medtronic, Minneapolis, MN, USA) in 9.7%. Median survival time for the entire cohort was 68.2 months (95% Confidence Interval [CI]; Lower Limit [LL] 58.0 months, Upper Limit [UL] not defined). The 2- and 5-year estimates of survival were 85% (LL 80%, UL 90%) and 56% (LL 48%, UL 66%), respectively. There was no statistically significant difference in median survival between the ES and ESXT valves, or implantation approach. Survival was greater in patients with creatinine <200 µmol/L compared to >200 µmol/L (68.8 months [LL 61.4, UL n/a] vs 48.0 months [LL 25.5, UL n/a]). Over the study period, there was a statistically significant trend in increasing mean transvalvular gradient (ES: 1.66 mmHg/yr, p=0.0058; ESXT: 2.50 mmHg/yr, p≤0.001) and maximum velocity (ESXT: 0.16 m/s/yr, p=0.004) and decreasing valve area (ESXT: -0.07 cm2/yr, p<0.001). There was substantial attrition of patient echocardiographic follow-up (number of echocardiograms followed up at 5 years=6, number at risk=41). CONCLUSIONS: This study has demonstrated acceptable survival in a high-risk cohort of patients undergoing TAVI, with comparable results to larger international experiences. There was a trend for worsening haemodynamics that needs to be monitored. Future studies need to examine patient quality of life and the performance of newer generation prostheses.

RESUMEN

Background The hardware and software differences between MR vendors and individual sites influence the quantification of MR spectroscopy data. An analysis of a large data set may help to better understand sources of the total variance in quantified metabolite levels. Purpose To compare multisite quantitative brain MR spectroscopy data acquired in healthy participants at 26 sites by using the vendor-supplied single-voxel point-resolved spectroscopy (PRESS) sequence. Materials and Methods An MR spectroscopy protocol to acquire short-echo-time PRESS data from the midparietal region of the brain was disseminated to 26 research sites operating 3.0-T MR scanners from three different vendors. In this prospective study, healthy participants were scanned between July 2016 and December 2017. Data were analyzed by using software with simulated basis sets customized for each vendor implementation. The proportion of total variance attributed to vendor-, site-, and participant-related effects was estimated by using a linear mixed-effects model. P values were derived through parametric bootstrapping of the linear mixed-effects models (denoted Pboot). Results In total, 296 participants (mean age, 26 years ± 4.6; 155 women and 141 men) were scanned. Good-quality data were recorded from all sites, as evidenced by a consistent linewidth of N-acetylaspartate (range, 4.4-5.0 Hz), signal-to-noise ratio (range, 174-289), and low Cramér-Rao lower bounds (≤5%) for all of the major metabolites. Among the major metabolites, no vendor effects were found for levels of myo-inositol (Pboot > .90), N-acetylaspartate and N-acetylaspartylglutamate (Pboot = .13), or glutamate and glutamine (Pboot = .11). Among the smaller resonances, no vendor effects were found for ascorbate (Pboot = .08), aspartate (Pboot > .90), glutathione (Pboot > .90), or lactate (Pboot = .28). Conclusion Multisite multivendor single-voxel MR spectroscopy studies performed at 3.0 T can yield results that are coherent across vendors, provided that vendor differences in pulse sequence implementation are accounted for in data analysis. However, the site-related effects on variability were more profound and suggest the need for further standardization of spectroscopic protocols. © RSNA, 2020 Online supplemental material is available for this article.

RESUMEN

BACKGROUND: Care home residents are increasingly frail with complex health and social care needs. Their transfer to hospital at the end-of-life can be associated with unwanted interventions and distress. However, hospitals do enable provision of care that some residents wish to receive. We aimed to explore the factors that influence hospital admission of care home residents who then died in hospital. METHODS: This study combined in-depth case note review of care home residents dying in two Scottish teaching hospitals during a 6-month period and semi-structured interviews with a purposive sample of 26 care home staff and two relatives. RESULTS: During the 6-month period, 109 care home residents died in hospital. Most admissions occurred out-of-hours (69%) and most were due to a sudden event or acute change in clinical condition (72%). Length of stay in hospital before death was short, with 42% of deaths occurring within 3 days. Anticipatory Care Planning (ACP) regarding hospital admission was documented in 44%.Care home staff wanted to care for residents who were dying; however, uncertain trajectories of decline, acute events, challenges of ACP, relationship with family and lack of external support impeded this. CONCLUSIONS: Managing acute changes on the background of uncertain trajectories is challenging in care homes. Enhanced support is required to improve and embed ACP in care homes and to provide rapid, 24 hours-a-day support to manage difficult symptoms and acute changes.

RESUMEN

BACKGROUND: Risk prediction after myocardial infarction is often complex in older patients. The Global Registry of Acute Coronary Events (GRACE) model includes clinical parameters and age, but not frailty. We hypothesised that frailty would enhance the prognostic properties of GRACE. METHODS: We performed a prospective observational cohort study in two independent cardiology units: the Royal Infirmary of Edinburgh, UK (primary cohort) and the South Yorkshire Cardiothoracic Centre, Sheffield, UK (external validation). The study sample included 198 patients ≥65 years old hospitalised with type 1 myocardial infarction (primary cohort) and 96 patients ≥65 years old undergoing cardiac catheterisation for myocardial infarction (external validation). Frailty was assessed using the Clinical Frailty Scale (CFS). The GRACE 2.0 estimated risk of 12-month mortality, Charlson comorbidity index and Karnofsky disability scale were also determined for each patient. RESULTS: Forty (20%) patients were frail (CFS ≥5). These individuals had greater comorbidity, functional impairment and a higher risk of death at 12 months (49% vs. 9% in non-frail patients, p < 0.001). The hazard of 12-month all-cause mortality nearly doubled per point increase in CFS after adjustment for age, sex and comorbidity (Hazard Ratio [HR] 1.90, 95% CI 1.47-2.44, p < 0.001). The CFS had good discrimination for mortality by Receiver Operating Characteristic (ROC) curve analysis (Area Under the Curve [AUC] 0.81, 95% CI 0.72-0.89) and enhanced the GRACE estimate (AUC 0.86 vs. 0.80 without CFS, p = 0.04). At existing GRACE thresholds, the CFS resulted in a Net Reclassification Improvement (NRI) of 0.44 (95% CI 0.28-0.60, p < 0.001), largely through reductions in risk estimates amongst non-frail patients. Similar findings were observed in the external validation cohort (NRI 0.46, 95% CI 0.23-0.69, p < 0.001). CONCLUSIONS: The GRACE score overestimated mortality risk after myocardial infarction in these cohorts of older patients. The CFS is a simple guided frailty tool that may enhance prediction in this setting. These findings merit evaluation in larger cohorts of unselected patients. TRIAL REGISTRATION: Clinicaltrials.gov; NCT02302014 (November 26th 2014, retrospectively registered).

RESUMEN

There is large individual variability in human neural responses and perceptual abilities. The factors that give rise to these individual differences, however, remain largely unknown. To examine these factors, we measured fMRI responses to moving gratings in the motion-selective region MT, and perceptual duration thresholds for motion direction discrimination. Further, we acquired MR spectroscopy data, which allowed us to quantify an index of neurotransmitter levels in the region of area MT. These three measurements were conducted in separate experimental sessions within the same group of male and female subjects. We show that stronger Glx (glutamate + glutamine) signals in the MT region are associated with both higher fMRI responses and superior psychophysical task performance. Our results suggest that greater baseline levels of glutamate within MT facilitate motion perception by increasing neural responses in this region.

RESUMEN

Accurate and reliable quantification of brain metabolites measured in vivo using 1H magnetic resonance spectroscopy (MRS) is a topic of continued interest. Aside from differences in the basic approach to quantification, the quantification of metabolite data acquired at different sites and on different platforms poses an additional methodological challenge. In this study, spectrally edited γ-aminobutyric acid (GABA) MRS data were analyzed and GABA levels were quantified relative to an internal tissue water reference. Data from 284 volunteers scanned across 25 research sites were collected using GABA+ (GABA + co-edited macromolecules (MM)) and MM-suppressed GABA editing. The unsuppressed water signal from the volume of interest was acquired for concentration referencing. Whole-brain T1-weighted structural images were acquired and segmented to determine gray matter, white matter and cerebrospinal fluid voxel tissue fractions. Water-referenced GABA measurements were fully corrected for tissue-dependent signal relaxation and water visibility effects. The cohort-wide coefficient of variation was 17% for the GABA + data and 29% for the MM-suppressed GABA data. The mean within-site coefficient of variation was 10% for the GABA + data and 19% for the MM-suppressed GABA data. Vendor differences contributed 53% to the total variance in the GABA + data, while the remaining variance was attributed to site- (11%) and participant-level (36%) effects. For the MM-suppressed data, 54% of the variance was attributed to site differences, while the remaining 46% was attributed to participant differences. Results from an exploratory analysis suggested that the vendor differences were related to the unsuppressed water signal acquisition. Discounting the observed vendor-specific effects, water-referenced GABA measurements exhibit similar levels of variance to creatine-referenced GABA measurements. It is concluded that quantification using internal tissue water referencing is a viable and reliable method for the quantification of in vivo GABA levels.

RESUMEN

OBJECTIVE: About 14% of cancer patients live with dependent children. Healthcare professionals are well placed to help patients support their children as part of a patient-centred practice. Children tend to appreciate open communication during the course of illness, but patients often find this difficult. However, research is unclear about patients' preferences and their willingness to talk with healthcare professionals about their dependent children. METHODS: We conducted 15 in-depth interviews with patients from haematological (N = 11) and gynaecological oncology (N = 4). The interviews and subsequent analysis focused on patients' communicative preferences, taking the theoretical framework of "biographical disruption" as a starting point and using Jenkins' concept of identity as a social, relational and dynamic process. RESULTS: We identified two overall identities at stake for seriously ill patients with parental responsibility: "patient identity" and "parent identity." As "patients," patients were ambivalent about relating to their children, but as "parents" they wanted healthcare professionals to talk about their children. CONCLUSION: In order to be patient-centred, clinicians should, we suggest, acknowledge that patients have these conflicting perspectives and identities, which surface at various times and situations throughout their illness trajectories. Research is needed to further explore these findings in different illness groups and cultures.

RESUMEN

BACKGROUND: Global annual deaths are rising. It is essential to examine where future deaths may occur to facilitate decisions regarding future service provision and resource allocation. AIMS: To project where people will die from 2017 to 2040 in an ageing country with advanced integrated palliative care, and to prioritise recommendations based on these trends. METHODS: Population-based trend analysis of place of death for people that died in Scotland (2004-2016) and projections using simple linear modelling (2017-2040); Transparent Expert Consultation to prioritise recommendations in response to projections. RESULTS: Deaths are projected to increase by 15.9% from 56,728 in 2016 (32.8% aged 85+ years) to 65,757 deaths in 2040 (45% aged 85+ years). Between 2004 and 2016, proportions of home and care home deaths increased (19.8-23.4% and 14.5-18.8%), while the proportion of hospital deaths declined (58.0-50.1%). If current trends continue, the numbers of deaths at home and in care homes will increase, and two-thirds will die outside hospital by 2040. To sustain current trends, priorities include: 1) to increase and upskill a community health and social care workforce through education, training and valuing of care work; 2) to build community care capacity through informal carer support and community engagement; 3) to stimulate a realistic public debate on death, dying and sustainable funding. CONCLUSION: To sustain current trends, health and social care provision in the community needs to grow to support nearly 60% more people at the end-of-life by 2040; otherwise hospital deaths will increase.

RESUMEN

What we see depends on the spatial context in which it appears. Previous work has linked the suppression of perceived contrast by surrounding stimuli to reduced neural responses in early visual cortex. This surround suppression depends on at least two separable neural mechanisms, "low-level" and "higher level," which can be differentiated by their response characteristics. We used electroencephalography to demonstrate for the first time that human occipital neural responses show evidence of these two suppression mechanisms. Eighteen adults (10 women, 8 men) each participated in three experimental sessions, in which they viewed visual stimuli through a mirror stereoscope. The first session was used to identify the C1 component, while the second and third comprised the main experiment. Event-related potentials were measured in response to center gratings either with no surround or with surrounding gratings oriented parallel or orthogonal, and presented in either the same eye (monoptic) or the opposite eye (dichoptic). We found that the earliest component of an event-related potential (C1; ∼60 ms) was suppressed by surrounding stimuli, but that suppression did not depend on surround configuration. This suggests a suppression mechanism that is not tuned for relative orientation acting on the earliest cortical response to the target. A later response component (N1; ∼160 ms) showed stronger suppression for parallel and monoptic surrounds, consistent with our earlier psychophysical results and a second form of suppression that is binocular and orientation tuned. We conclude that these two forms of surround suppression have distinct response time courses in the human visual system, which can be differentiated using electrophysiology.

RESUMEN

BACKGROUND: Case fatality after total anterior circulation stroke is high. Our objective was to describe the experiences and needs of patients and caregivers, and to explore whether, and how, palliative care should be integrated into stroke care. METHODS: From 3 stroke services in Scotland, we recruited a purposive sample of people with total anterior circulation stroke, and conducted serial, qualitative interviews with them and their informal and professional caregivers at 6 weeks, 6 months and 1 year. Interviews were transcribed for thematic and narrative analysis. The Palliative Care Outcome Scale, EuroQol-5D-5L and Caregiver Strain Index questionnaires were completed after interviews. We also conducted a data linkage study of all patients with anterior circulation stroke admitted to the 3 services over 6 months, which included case fatality, place of death and readmissions. RESULTS: Data linkage (n = 219) showed that 57% of patients with total anterior circulation stroke died within 6 months. The questionnaires recorded that the patients experienced immediate and persistent emotional distress and poor quality of life. We conducted 99 interviews with 34 patients and their informal and professional careers. We identified several major themes. Patients and caregivers faced death or a life not worth living. Those who survived felt grief for a former life. Professionals focused on physical rehabilitation rather than preparation for death or limited recovery. Future planning was challenging. "Palliative care" had connotations of treatment withdrawal and imminent death. INTERPRETATION: Major stroke brings likelihood of death but little preparation. Realistic planning with patients and informal caregivers should be offered, raising the possibility of death or survival with disability. Practising the principles of palliative care is needed, but the term "palliative care" should be avoided or reframed.

RESUMEN

BACKGROUND: Population ageing will lead to more deaths with an uncertain trajectory. Identifying patients at risk of dying could facilitate more effective care planning. AIM: To determine whether screening for likely death within 12 months is more effective using screening tools or intuition. DESIGN: Randomised controlled trial of screening tools (Surprise Question plus the Supportive and Palliative Care Indicators Tool for Surprise Question positive patients) to predict those at risk of death at 12 months compared with unguided intuition (clinical trials registry: ACTRN12613000266763). SETTING/PARTICIPANTS: Australian general practice. A total of 30 general practitioners (screening tool = 12, intuition = 18) screened all patients ( n = 4365) aged ≥70 years seen at least once in the last 2 years. RESULTS: There were 142 deaths (screening tool = 3.1%, intuition = 3.3%; p = 0.79). General practitioners identified more at risk of dying using Surprise Question (11.8%) than intuition (5.4%; p = 0.01), but no difference with Surprise Question positive then Supportive and Palliative Care Indicators Tool (5.1%; p = 0.87). Surprise Question positive predicted more deaths (53.2%, intuition = 33.7%; p = 0.001), but Surprise Question positive/Supportive and Palliative Care Indicators Tool predictions were similar (5.1%; p = 0.87 vs intuition). There was no difference in proportions correctly predicted to die (Surprise Question = 1.6%, intuition = 1.1%; p = 0.156 and Surprise Question positive/Supportive and Palliative Care Indicators Tool = 1.1%; p = 0.86 vs intuition). Screening tool had higher sensitivity and lower specificity than intuition, but no difference in positive or negative predictive value. CONCLUSION: Screening tool was better at predicting actual death than intuition, but with a higher false positive rate. Both were similarly effective at screening the whole cohort for death. Screening for possible death is not the best option for initiating end-of-life planning: recognising increased burden of illness might be a better trigger.

RESUMEN

BACKGROUND: Liver disease is an increasing cause of death worldwide but palliative care is largely absent for these patients. AIM: We conducted a feasibility trial of a complex intervention delivered by a supportive care liver nurse specialist to improve care coordination, anticipatory care planning and quality of life for people with advanced liver disease and their carers. DESIGN: Patients received a 6-month intervention (alongside usual care) from a specially trained liver nurse specialist. The nurse supported patients/carers to live as well as possible with the condition and acted as a resource to facilitate care by community professionals. A mixed-method evaluation was conducted. Case note analysis and questionnaires examined resource use, care planning processes and quality-of-life outcomes over time. Interviews with patients, carers and professionals explored acceptability, effectiveness, feasibility and the intervention. SETTING/PARTICIPANTS: Patients with advanced liver disease who had an unplanned hospital admission with decompensated cirrhosis were recruited from an inpatient liver unit. The intervention was delivered to patients once they had returned home. RESULTS: We recruited 47 patients, 27 family carers and 13 case-linked professionals. The intervention was acceptable to all participants. They welcomed access to additional expert advice, support and continuity of care. The intervention greatly increased the number of electronic summary care plans shared by primary care and hospitals. The Palliative care Outcome Scale and EuroQol-5D-5L questionnaire were suitable outcome measurement tools. CONCLUSION: This nurse-led intervention proved acceptable and feasible. We have refined the recruitment processes and outcome measures for a future randomised controlled trial.

RESUMEN

BACKGROUND: Heart failure is an emerging challenge for Sub Saharan Africa. However, research on patients' needs and experiences of care is scarce with little evidence available to support and develop services. We aimed to explore the experiences of patients living and dying with heart failure in Kenya. METHODS: We purposively recruited 18 patients admitted with advanced heart failure at a rural district hospital in Kenya. We conducted serial in depth interviews with patients at 0, 3 and 6 months after recruitment, and conducted bereavement interviews with carers. Interviews were recorded, transcribed into English and analyzed using a thematic approach, assisted by Nvivo software package. RESULTS: Forty-four interviews were conducted. Patients experienced physical, psychosocial, spiritual and financial distress. They also had unmet needs for information about their illness, how it would affect them and how they could get better. Patients experience of and their interpretation of symptoms influenced health care seeking. Patients with acute symptoms sought care earlier than those with more gradual symptoms which tended to be normalised as part of daily life or assumed to be linked to common treatable conditions. Nearly all patients expected to be cured and were frustrated by a progressive illness poorly responsive to treatment. Accumulating costs was a barrier to continuity of care and caused tensions in social relationships. Patients valued information on the nature of their illness, prognosis, self-care, lifestyle changes and prevention strategies, but this was rarely available. CONCLUSIONS: This is the first in-depth study to explore the experiences of people living with advanced heart failure in Kenya. This study suggests that patients would benefit from holistic care, such as a palliative approach that is aimed at providing multidimensional symptom management. A palliative approach to services should be provided alongside chronic disease management aimed at primary prevention of risk factors, and early identification and initiation of disease modifying therapy. Further research is needed to determine best practice for integrating palliative care for people living and dying with heart failure.
