Frailty in the prediction of delirium in the intensive care unit: A secondary analysis of the Deli study.

BACKGROUND: Delirium is an acute disorder of attention and cognition with an incidence of up to 70% in the adult intensive care setting. Due to the association with significantly increased morbidity and mortality, it is important to identify who is at the greatest risk of an acute episode of delirium while being cared for in the intensive care. The objective of this study was to determine the ability of the cumulative deficit frailty index and clinical frailty scale to predict an acute episode of delirium among adults admitted to the intensive care. METHODS: This study is a secondary analysis of the Deli intervention study, a hybrid stepped-wedge cluster randomized controlled trial to assess the effectiveness of a nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to the four adult intensive care units in the south-west of Sydney, Australia. Important predictors of delirium were identified using a bootstrap approach and the absolute risks, based on the cumulative deficit frailty index and the clinical frailty scale are presented. RESULTS: During the 10-mth data collection period (May 2019 and February 2020) 2566 patients were included in the study. Both the cumulative deficit frailty index and the clinical frailty scale on admission, plus age, sex, and APACHE III (AP III) score were able to discriminate between patients who did and did not experience an acute episode of delirium while in the intensive care, with AUC of 0.701 and 0.703 (moderate discriminatory ability), respectively. The addition of a frailty index to a prediction model based on age, sex, and APACHE III score, resulted in net reclassified of risk. Nomograms to individualize the absolute risk of delirium using these predictors are also presented. CONCLUSION: We have been able to show that both the cumulative deficits frailty index and clinical frailty scale predict an acute episode of delirium among adults admitted to intensive care.

Advance Care Planning in Patients with Suspected or Proven COVID: Are We Meeting Our Own Standards?

OBJECTIVE: Given the importance of advance care planning (ACP) in the context of a pandemic, we aimed to assess current adherence to local policy recommending ACP in all hospitalised adult patients with suspected or proven COVID-19 at Liverpool Hospital, Sydney, Australia. DESIGN: A retrospective cohort study. SETTING: A tertiary referral and teaching hospital. PARTICIPANTS: A select sample of adult patients admitted to Liverpool Hospital in 2019-2021 with suspected or proven COVID-19. MAIN OUTCOME MEASURES: Proportion of patients with documented ACP and format of ACP. RESULTS: Amongst 209 patients with proven or suspected COVID-19 hospitalised between March 2019 through to September 2021, median frailty score was 3, the median Charlson Comorbidity Score was 4, median age of the patients was 71 years, and median length of hospital stay was 5 days (range 0-98 days). Almost all patients were tested for COVID-19 (n = 207, 99%) of which 15% (31) were positive. Fewer than a quarter of the patients had documented ACPs (50, 24%) and 17 patients had existing formal advance care directives. Patients who had ACP were older, more likely to be frail and more likely to have higher rates of comorbidity compared to those without ACP. ACP was more commonly discussed with family members (41/50) than patients (25/50) and others (5/50). CONCLUSION: Adherence to the local ACP policy mandating such discussions was low. This reinforces the need for prioritising ACP discussions, especially for unwell patients such as those with COVID, likely involving further input to improve awareness and rates of formal documentation.

Residential Aged Care Facilities During the COVID-19 Pandemic: A Staff Survey on Impact and Resources.

The current study explored the impact of the coronavirus disease 2019 (COVID-19) pandemic on staff in residential aged care facilities (RACFs). A hardcopy, voluntary, anonymous survey was circulated to local RACFs (June-July 2020), exploring challenges, staffing effects, mood within RACFs, and staff perceptions of supports. Overall, 105 staff members responded, which were mainly nursing personnel (67.6%) and owners/managers (10.5%). Seventy percent believed they were equipped to handle patients with COVID-19. One quarter reported personal protective equipment shortages. Respondents reported pressures to accept patients with COVID-19 from hospitals and/or keep residents in the RACF. One third reported staff "calling in sick" related to COVID-19/quarantine. Common compensatory strategies included increasing part-time workers' hours. Reported mood was largely positive. Most (86.4%) respondents felt supported by general practitioner and local geriatric outreach services. Opportunities to best support RACF staff require further research and dialogue.

Frailty and risk of subsequent fracture among older adults presenting to hospital with a minimal trauma fracture.

We investigated frailty and refracture risk among older adults with a minimal trauma fracture. After adjusting for age, sex, and site of initial fracture, increasing frailty was associated with an increased risk subsequent fracture. These results indicate the need to routinely screen for frailty following an initial fracture among older adults. INTRODUCTION: Minimal trauma fractures are common among older adults, and frailty increases risk of an initial minimal trauma fracture. This study was undertaken to estimate the risk of subsequent fracture based on frailty status at the time of an initial fracture. METHODS: The study population was older adults presenting to hospital, aged 60 years or more, with a minimal trauma fracture. Frailty was estimated using a cumulative deficit approach. The risk of subsequent fracture based on increasing cumulative frailty deficit item group, adjusted for sex, age, and site of initial fracture, was estimated using Cox's proportional hazard model. RESULTS: Between January 2014 and December 2020, 12,115 older adults presented to hospital (8371 women [69%]), with an initial minimal trauma fracture. The average age was 80 years (SD 9.5). Subsequent fractures identified during the follow-up period occurred in 1137 (9.4%) of study participants. The incidence of subsequent fracture ranged from 25.0 per 1000 older adults (95% confidence interval (CI) 22.4 to 27.8) among the lowest frailty deficit group (1 deficit item) to 31.8 per 1000 (95% CI 28.0 to 35.8) among the highest frailty deficit group (4 to 12 deficit items). After adjusting for age, sex, and site of initial fracture, an increasing number of frailty deficit items was associated with increased risk subsequent fracture (p-value for trend = 0.008). CONCLUSION: Our results indicate that following an initial minimal trauma fracture, frailty independently increases the risk of a subsequent fracture. Therefore, it is important at the time of an initial fracture that older women and men are screened for the presence of frailty, and models of care are implemented to reduce the risk of subsequent fracture among this vulnerable group of older adults.

Frailty among older surgical patients and risk of hospital acquired adverse events: The South-Western Sydney frailty and nurse sensitive indicators study.

BACKGROUND: While advances in healthcare mean people are living longer, increasing frailty is a potential consequence of this. The relationship between frailty among older surgical patients and hospital acquired adverse events has not been extensively explored. We sought to describe the relationship between increasing frailty among older surgical patients and the risk of hospital acquired adverse events. METHODS: We included consecutive surgical admissions among patients aged 70 years or more across the SWSLHD between January 2010 and December 2020. This study used routinely collected ICD-10-AM data, obtained from the government maintained Admitted Patient Data Collection. The relationships between cumulative frailty deficit items and risk of hospital acquired adverse events were assessed using Poisson regression modelling. This study followed the RECORD/STROBE guidelines. RESULTS: During the study period, 44,721 (57% women) older adults were admitted, and 41% (25,306) were planned surgical admissions. The risk of all adverse events increased with increasing number of frailty deficit items, the highest deficit items group (4-12 deficit items) compared with the lowest deficit items group (0 or 1 deficit item): falls adjusted rate ratio (adj RR) = 15.3, (95% confidence interval (CI) 12.1, 19.42); pressure injury adj RR = 21.3 (95% CI 12.53, 36.16); delirium adj RR = 40.9 (95% CI 31.21, 53.55); pneumonia adj RR = 16.5 (95% CI 12.74, 21.27); thromboembolism adj RR = 17.3 (95% CI 4.4, 11.92); and hospital mortality adj RR = 6.2 (95% CI 5.18, 7.37). CONCLUSION: The increase in number of cumulative frailty deficit items among older surgical patients was associated with a higher risk of adverse hospital events. The link offers an opportunity to clinical nursing professionals in the surgical setting, to develop and implement targeted models of care and ensure the best outcomes for frail older adults and their families.

Understanding of advance care planning in primary care: a gap analysis.

BACKGROUND: Although primary care is a well suited context for conducting advance care planning (ACP), there are many barriers to initiating discussions regarding future health preference and end-of-life conversations. METHODS: This qualitative study conducted 30 detailed individual interviews with senior administrators, medical and nurse practitioners of a local health district, NSW Ambulance, e-Health NSW, general practitioners and practice nurses to find out about barriers to ACP in South Western Sydney. RESULTS: Thematic analysis was conducted on the interviews. Six major themes were identified: Prevalence; Empowerment of roles and responsibilities; Lack of training/knowledge/confidence; Fragmentation of care; Patient/family readiness; and Prognostication. Half of the participants were willing to use a prognostic tool to identify when a patient was likely to be at the end of their life and provide a prompt to initiate ACP. CONCLUSION: In addition to addressing training and acknowledging resource constraints, these findings suggest that if a prognostic tool was validated and practical in a primary care setting, it may provide valuable assistance to encourage everyone in society to begin discussing this issue and completing ACP.

Identifying the needs of our older community-based patients in the COVID era: A telephone survey.

Background: Older people's vulnerability during a pandemic may extend to social connectedness, access to healthcare, and information delivery. We sought to identify whether and how older community-based patients are maintaining connections and accessing information during COVID-19. Methods: We administered a telephone questionnaire to all patients (or carer/proxy answering 'on patient's behalf') who previously attended our Geriatric Medicine clinic, May-December 2019. Results: Response rate was 58.8% (151/257), carer respondents comprising 23.8% (36/151). Mean patient age was 81.8 years (SD 8.6); 59.6% were female, 15.2% lived alone. English was the preferred language for 72.9% (110/151). Almost half (46.4%, 70/151) felt COVID-related restrictions had impacted them. Thirty-eight percent (58/151) reported feelings of social isolation, most (38/58) reporting this new since COVID. Nonetheless, 92.1% (139/151) reported maintaining social connections, all with family (139/139), less often with friends (69.8%, 97/139). COVID-related information sources included television 68.9% (104/151), family/friends (54.3%), healthcare providers (24.5%), and written sources (21.2%, 32/151); 12.6% used online resources. Increasing age lowered likelihood of accessing online information, while having smartphone/computer increased. Most (82.6%) believed their healthcare needs were being met, and 76.1% had accessed their GP, 87% (100/115) in-person. Only 33.1% (50/151) agreed telehealth acceptable, more often those with smartphone/computer (OR 2.15, p=0.04). Conclusions: Interventions to reduce isolation and optimize connectedness and healthcare- despite physical distancing- are important during COVID-19. During a rapidly evolving pandemic, healthcare delivery and information provision to our older population is likely best served by a multifaceted approach which acknowledges identified preferences, practices and barriers.

Concerns and potential improvements in end-of-life care from the perspectives of older patients and informal caregivers: a scoping review.

BACKGROUND: Overtreatment in advanced age i.e. aggressive interventions that do not improve survival and are potentially harmful, can impair quality of care near the end of life (EOL). As healthcare provider perspectives on care quality may differ from that of service users, the aim of this study was to explore the views of older patients near EOL or their caregivers about the quality of health care at the EOL based on their lived experience, and to identify healthcare service improvements. METHODS: Medline and backward citation searches were conducted for qualitative or quantitative studies reported on the views of patients and/or informal caregivers about EOL care quality. Thematic analysis was used to summarise qualitative data (primary analysis); narrative and tabulations were used to summarise quantitative data (secondary analysis). RESULTS: Thirty articles met the inclusion criteria. Five main qualitative themes regarding quality care emerged: (1) Effective communication between clinicians and patients/caregivers; (2) Healthcare that values patient preferences and shared decision making; (3) Models of care that support quality of life and death with dignity; (4) Healthcare services that meet patient expectations; and (5) Support for informal caregivers in dealing with EOL challenges. The quantitative articles supported various aspects of the thematic framework. CONCLUSION: The findings of this study show that many of the issues highlighted by patients or bereaved relatives have persisted over the past two decades. There is an urgent need for comprehensive evaluation of care across the healthcare system and targeted redesign of existing EOL care pathways to ensure that care aligns with what patients and informal caregivers consider high-quality patient-centred care at the EOL.

Frailty, delirium and hospital mortality of older adults admitted to intensive care: the Delirium (Deli) in ICU study.

BACKGROUND: Clinical frailty among older adults admitted to intensive care has been proposed as an important determinant of patient outcomes. Among this group of patients, an acute episode of delirium is also common, but its relationship to frailty and increased risk of mortality has not been extensively explored. Therefore, the aim of this study was to explore the relationship between clinical frailty, delirium and hospital mortality of older adults admitted to intensive care. METHODS: This study is part of a Delirium in Intensive Care (Deli) Study. During the initial 6-month baseline period, clinical frailty status on admission to intensive care, among adults aged 50 years or more; acute episodes of delirium; and the outcomes of intensive care and hospital stay were explored. RESULTS: During the 6-month baseline period, 997 patients, aged 50 years or more, were included in this study. The average age was 71 years (IQR, 63-79); 55% were male (n = 537). Among these patients, 39.2% (95% CI 36.1-42.3%, n = 396) had a Clinical Frailty Score (CFS) of 5 or more, and 13.0% (n = 127) had at least one acute episode of delirium. Frail patients were at greater risk of an episode of delirium (17% versus 10%, adjusted rate ratio (adjRR) = 1.71, 95% confidence interval (CI) 1.20-2.43, p = 0.003), had a longer hospital stay (2.6 days, 95% CI 1-7 days, p = 0.009) and had a higher risk of hospital mortality (19% versus 7%, adjRR = 2.54, 95% CI 1.72-3.75, p < 0.001), when compared to non-frail patients. Patients who were frail and experienced an acute episode of delirium in the intensive care had a 35% rate of hospital mortality versus 10% among non-frail patients who also experienced delirium in the ICU. CONCLUSION: Frailty and delirium significantly increase the risk of hospital mortality. Therefore, it is important to identify patients who are frail and institute measures to reduce the risk of adverse events in the ICU such as delirium and, importantly, to discuss these issues in an open and empathetic way with the patient and their families.

Serum lipids associated with inflammation-related PET-FDG uptake in symptomatic carotid plaque.

OBJECTIVE: We hypothesized that serum lipids, which experimental data suggest may be key initiators of carotid plaque inflammation, would be associated with plaque inflammation on (18)fluorodeoxyglucose (FDG)-PET in patients with acutely symptomatic carotid stenosis. METHODS: In this cohort study, consecutive patients with acute symptomatic internal carotid artery (ICA) stenosis (≥50%) underwent carotid PET-CT. We quantified plaque FDG uptake as follows: (1) average maximum standardized uptake values (SUVmax) across 10 regions of interest (ROI); (2) highest single ROI SUV measure (SUVROImax); (3) averaged mean SUV across 10 ROIs (SUVmean). RESULTS: Sixty-one patients were included. Plaque inflammatory FDG SUVmax was associated with increasing tertiles of low-density lipoprotein (LDL) (trend p = 0.004), total cholesterol (p = 0.009), and triglycerides (p = 0.01), and with lower high-density lipoprotein (HDL) (p = 0.005). When analyzed as a continuous variable, LDL was associated with symptomatic ICA SUVmean (Spearman rho 0.44, p = 0.009), SUVROImax (rho 0.33, p = 0.01), and SUVmax (rho 0.35, p = 0.06). Total cholesterol was associated with SUVmean (rho 0.33, p = 0.009), with trends for SUVmax (rho 0.24, p = 0.059) and SUVROImax (rho 0.23, p = 0.08). Triglycerides were associated with SUVmax (rho 0.32, p = 0.01) and SUVROImax (rho 0.35, p = 0.005). HDL was associated with lower SUVmax (rho -0.37, p = 0.004) and SUVROImax (rho -0.44, p = 0.0004). On multivariable linear regression analysis adjusting for age, sex, degree of carotid stenosis, statins, and smoking, LDL (p = 0.008) and total cholesterol (p = 0.04) were independently associated with SUVmax. CONCLUSION: Serum LDL and total cholesterol were associated with acutely symptomatic carotid plaque FDG uptake, supporting experimental data suggesting lipids may promote plaque inflammation, mediating rupture and clinical events.
