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.

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 impact of frailty and geriatric syndromes on metrics of acute care performance: results of a national day of care survey.

Background: Frailty is associated with a range of adverse clinical outcomes in the acute hospital setting. We sought to determine whether frailty and related factors affected clinical processes such as time to assessment during emergency hospital admission within the National Health Service (NHS) in the UK. Methods: The Society for Acute Medicine Benchmarking Audit (SAMBA) is an annual cross-sectional day of care survey. SAMBA 2022 was conducted on Thursday 23rd June 2022. We assessed whether the Clinical Frailty Scale (CFS) and presence of a geriatric syndrome affected performance against nationally recognised clinical quality indicators based on time to initial assessment and time to consultant review. CFS was graded into robust (CFS1-3), mild (CFS 4-5), moderate (CFS 6), severe (CFS7-8) and terminal illness (CFS 9). Plausible values were created for missing variables using multi-level multiple imputation. The association was described using mixed effect generalised linear models adjusting for initial National Early Warning Score 2 (NEWS2) and time of arrival. Findings: A total of 152 hospitals provided patient level data relating to 7248 emergency medical admissions. Patients with mild, moderate and severe frailty were less likely to be assessed within 4 h of arrival (adjusted OR, mild 0.79, 95% CI 0.68-0.96, moderate 0.67 95% CI 0.53-0.84, severe, 0.75 95% CI 0.58-0.96, terminally ill 0.59 95% CI 0.23-1.43) and less likely to be achieve the clinical quality indicator for consultant review (adjusted OR, mild 0.69 95% CI 0.58-0.83, moderate 0.55 95% CI 0.44-0.70, severe 0.54 95% CI 0.41-0.69, terminally ill 0.76 95% CI 0.42-1.5). Patients with geriatric syndromes were also less likely to be assessed within 4 h of arrival (adjusted OR 0.66 95% CI 0.56-0.76) or by a consultant within the recommended time frame (adjusted OR 0.45 95% CI 0.39-0.51). The difference was partially explained by differential use of SDEC pathways. Sub-group analysis of 5148 patients assessed outside of SDEC areas demonstrated patients with geriatric syndromes (adjusted OR 0.71, 95% CI 0.60-0.83), but not frailty defined by CFS were less likely to be assessed within 4 h of arrival. Moderate and severe frailty and the presence of a geriatric syndrome were associated with a decreased likelihood of achieving the consultant review standard (moderate, adjusted OR 0.75, 95% CI 0.59-0.94, severe adjusted OR 0.75 95% CI 0.58-0.96, geriatric syndrome adjusted OR 0.59, 95% CI 0.50-0.69). Interpretation: Frailty is associated with delayed clinical assessment. This association may suggest a systemic issue with clinical prioritisation, with important implications for acute care policy. Funding: The database for SAMBA is funded by the Society for Acute Medicine.

Nurse staffing levels within acute care: results of a national day of care survey.

INTRODUCTION: The relationship between nurse staffing levels and patient safety is well recognised. Inadequate provision of nursing staff is associated with increased medical error, as well as higher morbidity and mortality. Defining what constitutes safe nurse staffing levels is complex. A range of guidance and planning tools are available to inform staffing decisions. The Society for Acute Medicine (SAM) recommend a 'nurse-to-bed'ratio of greater than 1:6. Whether this standard accurately reflects the pattern and intensity of work on the Acute Medical Unit (AMU) is unclear. METHODS: Nurse staffing levels in AMUs were explored using the Society for Acute Medicine Benchmarking Audit 2019 (SAMBA19). Data from 122 acute hospitals were analysed. Nurse-to-bed ratios were calculated and compared. Estimates of the total nursing time available within the acute care system were compared to estimates of the time required to perform nursing activities. RESULTS: The total number of AMU beds across all 122 units was 4997. The mean daytime nurse-to-bed ratio was 1:4.3 and the mean night time nurse-to-bed ratio was 1:5.2. The SAM standard of a nurse to bed ratio of greater than 1:6 was achieved in 99 units (81.9%) during daytime hours and achieved by 74 units (60.6%) at night. The estimated time required to deliver direct clinical care was 35,698 h. A deficit of 4128 h (11.5% of time required) was estimated, representing the time difference between the total number of nursing hours available with current staffing and the estimated time needed for direct clinical care across all participating units. CONCLUSION: This UK-wide study suggests a significant proportion of AMUs do not meet the recommenced SAM staffing levels, particularly at night. A difference was observed between the total number of nursing hours within the acute care system and the estimated time required to perform direct nursing activities. This suggests a workforce shortage of nurses within acute care at the system level.

Frailty assessment and acute frailty service provision in the UK: results of a national 'day of care' survey.

BACKGROUND: The incorporation of acute frailty services into the acute care pathway is increasingly common. The prevalence and impact of acute frailty services in the UK are currently unclear. METHODS: The Society for Acute Medicine Benchmarking Audit (SAMBA) is a day of care survey undertaken annually within the UK. SAMBA 2019 (SAMBA19) took place on Thursday 27th June 2019. A questionnaire was used to collect hospital and patient-level data on the structure and organisation of acute care delivery. SAMBA19 sought to establish the frequency of frailty assessment tool use and describe acute frailty services nationally. Hospitals were classified based on the presence of acute frailty services and metrics of performance compared. RESULTS: A total of 3218 patients aged ≥70 admitted to 129 hospitals were recorded in SAMBA19. The use of frailty assessment tools was reported in 80 (62.0%) hospitals. The proportion of patients assessed for the presence of frailty in individual hospitals ranged from 2.2 to 100%. Bedded Acute Frailty Units were reported in 65 (50.3%) hospitals. There was significant variation in admission rates between hospitals. This was not explained by the presence of a frailty screening policy or presence of a dedicated frailty unit. CONCLUSION: Two fifths of participating UK hospitals did not have a routine frailty screening policy: where this existed, rates of assessment for frailty were variable and most at-risk patients were not assessed. Responses to positive results were poorly defined. The provision of acute frailty services is variable throughout the UK. Improvement is needed for the aspirations of national policy to be fully realised.

Response to winter pressures in acute services: analysis from the Winter Society for Acute Medicine Benchmarking Audit.

BACKGROUND: There is increased demand for urgent and acute services during the winter months, placing pressure on acute medicine services caring for emergency medical admissions. Hospital services adopt measures aiming to compensate for the effects of this increased pressure. This study aimed to describe the measures adopted by acute medicine services to address service pressures during winter. METHODS: A survey of acute hospitals was conducted during the Society for Acute Medicine Benchmarking Audit, a national day-of-care audit, on 30th January 2020. Survey questions were derived from national guidance. Acute medicine services at 93 hospitals in the United Kingdom completed the survey, evaluating service measures implemented to mitigate increased demand, as well as markers of increased pressure on services. RESULTS: All acute internal medicine services had undertaken measures to prepare for increased demand, however there was marked variation in the combination of measures adopted. 81.7% of hospitals had expanded the number of medical inpatient beds available. 80.4% had added extra clinical staff. The specialty of the physicians assigned to provide care for extra inpatient beds varied. A quarter of units had reduced beds available for providing Same Day Emergency Care on the day of the survey. Patients had been waiting in corridors within the emergency medicine department in 56.3% of units. CONCLUSION: Winter pressure places considerable demand on acute services, and impacts the delivery of care. Although increased pressure on acute hospital services during winter is widely recognised, there is considerable variation in the approach to planning for these periods of increased demand.

Rapid response teams-how and who? A protocol for a randomised clinical trial evaluating the composition of the efferent limb of the rapid response system.

BACKGROUND: Many patients experiencing deterioration have documented deviation of vital signs prior to the deterioration event. Increasing focus on these patients led to the rapid response systems and their configuration with afferent and efferent limbs. The two most prevalent team constellations in the efferent limb are the medical emergency team (MET), usually led by a doctor, and the critical care outreach team (CCOT), usually led by a nurse. The two constellations have not previously been examined in a comparative clinical trial. METHODS: This is a single centre non-inferiority randomised controlled trial of MET vs CCOT. All patients will be randomised at the time of the call. The intervention group will be the critical care outreach team. The primary outcome is mortality at 30 days and the occurrence of serious adverse events. All patients will be followed for 90 days. We aim to detect or reject a change of 7% in mortality whilst accepting a type I error of 5 and type II error of 20, using a sample size of maximum of 2000 individual patients. DISCUSSION: There is evidence supporting a benefit for the patient when using rapid response systems; however, earlier randomised studies are marked by cross-contamination and selection bias. Previous studies have primarily examined the effect of RRS on hospital cardiac arrests (IHCA) and mortality. Our study will be examining the effect on intensive care unit admissions as well as the ICHA and mortality. CONCLUSION: This study may highlight potential benefits of specific configurations of rapid response systems and their impact on safety outcomes.

Understanding what matters most to patients in acute care in seven countries, using the flash mob study design.

BACKGROUND: Truly patient-centred care needs to be aligned with what patients consider important, and is highly desirable in the first 24 h of an acute admission, as many decisions are made during this period. However, there is limited knowledge on what matters most to patients in this phase of their hospital stay. The objective of this study was to identify what mattered most to patients in acute care and to assess the patient perspective as to whether their treating doctors were aware of this. METHODS: This was a large-scale, qualitative, flash mob study, conducted simultaneously in sixty-six hospitals in seven countries, starting November 14th 2018, ending 50 h later. One thousand eight hundred fifty adults in the first 24 h of an acute medical admission were interviewed on what mattered most to them, why this mattered and whether they felt the treating doctor was aware of this. RESULTS: The most reported answers to "what matters most (and why)?" were 'getting better or being in good health' (why: to be with family/friends or pick-up life again), 'getting home' (why: more comfortable at home or to take care of someone) and 'having a diagnosis' (why: to feel less anxious or insecure). Of all patients, 51.9% felt the treating doctor did not know what mattered most to them. CONCLUSIONS: The priorities for acutely admitted patients were ostensibly disease- and care-oriented and thus in line with the hospitals' own priorities. However, answers to why these were important were diverse, more personal, and often related to psychological well-being and relations. A large group of patients felt their treating doctor did not know what mattered most to them. Explicitly asking patients what is important and why, could help healthcare professionals to get to know the person behind the patient, which is essential in delivering patient-centred care.

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.

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 triggers and interventions provided and a bedside assessment on the level of patients' frailty using a clinical frailty scale. RESULTS: Amongst 1133 patients, 40% were screened as frail, which was associated with older age (p < 0.001), admission under a medical speciality (p < 0.001), increased severity of illness at the time of the RRT review (p = 0.0047), and substantially higher frequency of limitations of care (p < 0.001). Importantly, 72% of patients screened as frail were either dead or dependent on hospital care by 30 days (p < 0.001). In the multivariable analysis, the significant risk factors for the composite endpoint "poor recovery" (died or were hospital-dependent by 30 days) were age (odds ratio (OR), 1.04; 95% confidence interval (CI), 1.03-1.05; p < 0.001), frailty level (p < 0.001), existing limitation of care (OR, 2.0; 95% CI, 1.3-3.0; p < 0.001), and the quick sequential organ failure assessment (qSOFA) score (p < 0.001). CONCLUSIONS: Higher frailty scores were associated with increased mortality and dependence on health care at 30 days. Our results indicate that frailty has an influence on the clinical trajectory of deteriorating patients and that such assessment should be included in discussion of goals and expectations of care.

The use of telemedicine to enhance secondary care: some lessons from the front line.

Digital technologies such as telemedicine have the potential to transform healthcare, but uptake has only recently gained momentum secondary to national policy drivers. This paper reviews the potential benefits of telemedicine in secondary care and explores the use of video conferencing to support the hospital follow-up of older people with chronic disease, identifying a wide variety of issues that need to be addressed for successful implementation. We believe these issues will interest secondary care colleagues considering the use of telemedicine to support or substitute for some outpatient activities.

PRISMA Analysis of 30 Day Readmissions to a Tertiary Cancer Hospital.

BACKGROUND: Hospital readmissions are increasingly used as a quality indicator. Patients with cancer have an increased risk of readmission. The purpose of this study was to develop an in depth understanding of the causes of readmissions in patients undergoing cancer treatment using PRISMA methodology and was subsequently used to identify any potentially preventable causes of readmission in this cohort. METHODS: 50 consecutive 30 day readmissions from the 1st November 2014 to the medical admissions unit (MAU) at a specialist tertiary cancer hospital in the Northwest of England were analysed retrospectively. RESULTS: Q25(50%) of the patients were male with a median age of 59 years (range 19-81). PRISMA analysis showed that active (human) factors contributed to the readmission of 4 (8%) of the readmissions, which may have been potentially preventable. All of the readmissions were driven by a medical condition related to the patient's underlying cancer and ongoing cancer treatment. CONCLUSIONS: The majority of readmissions of patients undergoing cancer treatment appear to be related to the underlying condition and, as such, are predictable but not preventable. This suggests that hospital readmission is not a good quality indicator in this cohort of patients.

CREWS: improving specificity whilst maintaining sensitivity of the National Early Warning Score in patients with chronic hypoxaemia.

BACKGROUND: The National Early Warning Score (NEWS) is being introduced across the UK, but there are concerns about its specificity in patients with chronic hypoxaemia, such as some patients with COPD. This could lead to frequent clinically insignificant triggers and alarm fatigue. AIMS OF STUDY: To investigate whether patients with chronic hypoxaemia trigger excessively with NEWS, and to design a simple variant of NEWS for patients with chronic hypoxaemia: a Chronic Respiratory Early Warning Score (CREWS). METHODS: Data was collected from respiratory wards at two hospitals in North Wales. Components of NEWS and frequency of trigger thresholds being reached were recorded. CREWS was applied retrospectively to patients' observations. RESULTS: 196 admissions were analysed, including 78 for patients with chronic hypoxaemia. Patients with chronic hypoxaemia frequently exceeded trigger thresholds using NEWS during periods of stability/at discharge. Using CREWS, triggers during stability/at discharge were reduced from 32% of observations to 14% using a trigger threshold of a score greater than 6, and from 50% to 18% using a score greater than 5. All patients with chronic hypoxaemia who died within 30 days still reached CREWS trigger thresholds, and the area under receiver operated curves for NEWS and CREWS was comparable. CONCLUSION: CREWS is a simple variant of NEWS for patients with chronic hypoxaemia that could reduce clinically insignificant triggers and alarm fatigue, whilst still identifying the sickest patients.
