The Baby Boom and later life: is critical care fit for the future?

Populations around the world are ageing while in many developed countries the proportion of elderly patients admitted to critical care is rising. It is clear that age alone should not be used as a reason for refusing intensive care admission. Critical care in this patient group is challenging in many ways: with advancing age, several physiological changes occur which all lead to a subsequent reduction of physical performance and compensatory capacity, in many cases additionally aggravated by chronic illness. Subsequently, these age-dependent changes (with or without chronic illness) increase the risk for death, treatment costs and a prolonged length of intensive care and hospital stay. This review explores the potential of using co-morbidity and frailty to predict outcome and to help to make better decisions about critical care admission in the elderly. The authors explore the challenges of using different frailty assessment tools and offer a model for holistic approach to answer these questions

Exercise testing to guide safe discharge from hospital in COVID-19: a scoping review to identify candidate tests

Objectives We aimed to identify exercise tests that have been validated to support a safe discharge to home in patients with or without COVID-19.Study design Scoping review, using PRISMA-ScR reporting standards. Medline, PubMed, AMED, Embase, CINAHL and LitCovid databases were searched between 16 and 22 February 2021, with studies included from any publication date up to and including the search date.Intervention Short exercise tests.Primary outcome measures Safe discharge from hospital, readmission rate, length of hospital stay, mortality. Secondary outcomes measures: safety, feasibility and reliability.Results Of 1612 original records screened, 19 studies were included in the analysis. These used a variety of exercise tests in patients with chronic obstructive pulmonary disease, suspected pulmonary embolism and pneumocystis carinii pneumonia, heart failure or critical illness. Only six studies had examined patients with COVID-19, of these two were still recruiting to evaluate the 1 min sit-to-stand test and the 40-steps test. There was heterogeneity in patient populations, tests used and outcome measures. Few exercise tests have been validated to support discharge decisions. There is currently no support for short exercise tests for triage of care in patients with COVID-19.Conclusions Further research is needed to aid clinical decision-making at discharge from hospital

Towards NEWS 3.0: development and validation of an oxygen therapy adjusted National Early Warning Score. A statistical analysis plan

Introduction Early warning scores (EWS) use routinely measured vital signs to identify patients at risk of deterioration. The National Early Warning Score 2 (NEWS2) is mandated for use by NHS England in all acute trusts. Within NEWS2, oxygen therapy is scored using a binary approach — patients receive 2 points if they are receiving supplemental oxygen and 0 points if they are breathing room air. Examples of binary oxygen EWS are widespread, including other nationally employed EWS. Some have expressed concerns that deterioration is missed when patients require an escalating amount of supplemental oxygen in the absence of other vital sign derangements. This study aims to adapt and validate a version of NEWS2 that accounts for the amount of supplemental oxygen therapy the patient receives (NEWS2-O2). Methods We will use data from four NHS healthcare trusts across the UK to develop and validate an oxygen therapy adjusted NEWS2 score. We will also explore the time trends of oxygen requirement and other vital signs prior to deterioration. We will perform an external validation of other oxygen adjusted vital sign only EWS identified in a prior systematic review. Generalisability and implications This work will explore the quantification and handling of oxygen therapy within an EWS. We aim to provide an example to the NEWS Development Group on how oxygen can be incorporated into the next iteration of NEWS

Advance care planning in patients referred to hospital for acute medical care: Results of a national day of care survey.

Background:Advance care planning (ACP) is a voluntary process of discussion about future care between an individual and their care provider. ACP is a key focus of national policy as a means to improve patient centered care at the end-of-life. Despite a wide held belief that ACP is beneficial, uptake is sporadic with considerable variation depending on age, ethnicity, location and disease group. Methods:This study looked to establish the prevalence of ACP on initial presentation to hospital with a medical emergency within The Society for Acute Medicine Benchmarking Audit (SAMBA18). 123 acute hospitals from across the UK collected data during a day of care survey. The presence of ACP and the presence of 'Do Not Attempt Cardiopulmonary Resuscitation' orders were recorded separately. Findings:Among 6072 patients presenting with an acute medical emergency, 290 patients (4.8%) had an ACP that was available for the admitting medical team. The prevalence of ACP increased incrementally with age, in patients less than 80 years old the prevalence was 2·9% (95% CI 2·7-3·1) compared with 9·5% (95% CI 9·1-10·0%) in patients aged over 80. In the patients aged over 90 the prevalence of ACP was 12·6% (95% CI 9·8-16·0). ACP was present in 23·3% (95% CI 21.8-24.8%) of patients admitted from institutional care compared with 3·5% (95% CI 3·3-3·7) of patients admitted from home. The prevalence of ACP was 7.1% (95% CI 6·6-7·6) amongst patients re-admitted to the hospital within the previous 30 days. Interpretation:Very few patients have an ACP that is available to admitting medical teams during an unscheduled hospital admission. Even among patients with advanced age, and who have recently been in hospital, the prevalence of available ACP remains low, in spite of national guidance. Further interventions are needed to ensure that patients' wishes for care are known by providers of acute medical care

Acute frailty services:results of a national day of care survey

Introduction: Older people living with frailty are at high risk of emergency hospital admission and often have complex care needs which may not be adequately met by conventional models of acute care. This has driven the introduction of adaptations to acute care pathways designed to improve outcomes in this patient group. The identification of differences in the organisational approach to frailty may highlight opportunities for quality improvement.Methods: The Society for Acute Medicine Benchmarking audit is a national service evaluation which uses a single day-of-care methodology to record patient and organisational level data. All acute hospitals in the United Kingdom are eligible to participate. Emergency admissions referred to acute medical services between 00:00 and 23:59 on Thursday 23rd June 2022 were recorded. Information on the structure and operational design of acute frailty services was collected. The use of a validated frailty assessment tool, clinical frailty scale within the first 24 h of admission, assessment by an acute frailty service and clinical outcomes were reported in patients aged 70 year and above. A mixed effect generalised linear model was used to determine factors associated same-day discharge without overnight stay in patients with frailty.Results: A total of 152 hospitals participated. There was significant heterogeneity in the operational design and staffing model of acute frailty services. The presence of an acute frailty unit was reported in 57 (42.2%) hospitals. The use of validated frailty assessment tools was reported in 117 (90.0%) hospitals, of which 107 (91.5%) used the clinical frailty scale. Patient-level data were recorded for 3604 patients aged 70 years and above. At the patient level, 1626 (45.1%) were assessed using a validated tool during the admission process. Assessment by acute frailty services was associated with an increased likelihood of same-day discharge (adjusted OR 1.55, 95%CI 1.03- 2.39).Conclusion: There is significant variation in the provision of acute frailty services. Frailty-related policies and services are common at the organisational level but implemented inconsistently at the patient level. Older people with frailty or geriatric syndromes assessed by acute frailty services were more likely to be discharged without the need for overnight bed-based admission

The value of improving patient safety: Health-economic considerations for Rapid Response Systems – a Rapid Review of the Literature and Expert Round Table

Objectives Failure to rescue deteriorating patients in hospital is a well-researched topic. We aimed to explore the impact of safer care on health economic considerations for clinicians, providers and policymakers.Design We undertook a rapid review of the available literature and convened a round table of international specialists in the field including experts on health economics and value-based healthcare to better understand health economics of clinical deterioration and impact of systems to reduce failure to rescue.Results Only a limited number of publications have examined the health economic impact of failure to rescue. Literature examining this topic lacked detail and we identified no publications on long-term cost outside the hospital following a deterioration event. The recent pandemic has added limited literature on prevention of deterioration in the patients’ home.Cost-effectiveness and cost-efficiency are dependent on broader system effects of adverse events. We suggest including the care needs beyond the hospital and loss of income of patients and/or their informal carers as well as sickness of healthcare staff exposed to serious adverse events in the analysis of adverse events. They are likely to have a larger health economic impact than the direct attributable cost of the hospital admission of the patient suffering the adverse event. Premorbid status of a patient is a major confounder for health economic considerations.Conclusion In order to optimise health at the population level, we must limit long-term effects of adverse events through improvement of our ability to rapidly recognise and respond to acute illness and worsening chronic illness both in the home and the hospital

Performance of admission pathways within acute medicine services: Analysis from the Society for Acute Medicine Benchmarking Audit 2022 and comparison with performance 2019 - 2021

Urgent and emergency care services face increasing pressure, impacting patient care. We evaluated the performance of acute medicine services, assessing clinical quality indicators for unplanned medical admissions to acute hospital services. 152 acute UK hospital services accepting unplanned admissions to acute and general internal medicine completed a day-of-care survey incorporating organisational structure questionnaire and patient-level data over a pre-defined 24-hour period in June 2022. Clinical quality indicators were: Early Warning Score (EWS) measurement within 30 min of hospital arrival; clinician assessment within 4 h; assessment by consultant physician within 6 h (daytime) or 14 h (night-time). Results were compared with 2019, 2020, 2021. 7293 sequential patients were included (and compared with 19,817 patients across 2019–2021). In 2022, 69% of patients (95%CI 67.7–69.9%) had an EWS documented within 30 min. 79% of patients (95%CI 77.8–79.7%) were reviewed by a clinical decision maker within 4 h of hospital arrival. Patients assessed in Same Day Emergency Care services were more likely to meet this target than those assessed in Acute Medical Units or Emergency Departments (OR 2.4, 95%CI 2.02–2.87, p<0.001). Overall, 50% of patients received consultant physician review within the target time (3065/6161, 95%CI 48.5–51.0%); performance varied with time of arrival and location of initial assessment. Performance against all three clinical quality indicators was lower than 2019, 2020 and 2021 (p<0.001 for all). Performance against all quality indicators within acute medicine services is deteriorating. However, performance in Same Day Emergency Care Units is greater than in Acute Medical Units or Emergency Departments

The association of clinical frailty with outcomes of patients reviewed by rapid response teams: an international prospective observational cohort study

Background: Frailty is a state of vulnerability to poor resolution of homeostasis after a stressor event and is strongly associated with adverse outcomes. Therefore, the assessment of frailty may be an essential part of evaluation in any healthcare encounter that might result in an escalation of care. The purpose of the study was to assess the frequency and association of frailty with clinical outcomes in patients subject to rapid response team (RRT) review. Methods: In this multi-national prospective observational cohort study, centres with existing RRTs collected data over a 7-day period, with follow up of all patients at 24 h following their RRT call and at hospital discharge or 30 days following the event trigger (whichever came sooner). Investigators also collected data on the trigg

Feasibility and reliability of frailty assessment in the critically ill: a systematic review

Background. For healthcare systems, an ageing population poses challenges in the delivery of equitable and effective care. Frailty assessment has the potential to improve care in the intensive care setting, but applying assessment tools in critical illness may be problematic. The aim of this systematic review was to evaluate evidence for the feasibility and reliability of frailty assessment in critical care. Methods. Our primary search was conducted in Medline, Medline In-process, EMBASE, CINAHL, PsycINFO, AMED, Cochrane Database of Systematic Reviews, and Web of Science (January 2001 to October 2017). We included observational studies reporting data on feasibility and reliability of frailty assessment in critical care setting in patients 16 years and older. Feasibility was assessed in terms of timing of evaluation, the background, training and expertise required for assessors, and reliance upon proxy input. Reliability was assessed in terms of inter-rater reliability. Results. Data from 11 study publications are included, representing eight study cohorts and 7761 patients. Proxy involvement in frailty assessment ranged from 58- 100%. Feasibility data were not well-reported overall, but the exclusion rate due to lack of proxy availability ranged from 0 to 45%, the highest rate observed where family involvement was mandatory and the assessment tool relatively complex (Frailty Index, FI). Conventional elements of Frailty Phenotype (FP) assessment required modification prior to use in two studies. Clinical staff tended to use a simple judgement-based tool, the Clinical Frailty Scale (CFS). Inter-rater reliability was reported in one study using the CFS and although a good level of agreement was observed between clinician assessments, this was a small and single centre study. Conclusion. Though of unproven reliability in the critically ill, CFS was the tool used most widely by critical care clinical staff. Conventional FP assessment required modification for general application in critical care, and a FI-based assessment may be difficult to deliver by the critical care team on a routine basis. There is a high reliance on proxies for frailty assessment, and the reliability of frailty assessment tools in critical care needs further evaluation. PROSPERO CRD42016052073
