Which interventions are effective at decreasing or increasing emergency department attendances or hospital admissions from long-term care facilities? A systematic review.

OBJECTIVE: UK long-term care facility residents account for 185 000 emergency hospital admissions each year. Avoidance of unnecessary hospital transfers benefits residents, reduces demand on the healthcare systems but is difficult to implement. We synthesised evidence on interventions that influence unplanned hospital admissions or attendances by long-term care facility residents. METHODS: This is a systematic review of randomised controlled trials. PubMed, MEDLINE, EMBASE, ISI Web of Science, CINAHL and the Cochrane Library were searched from 2012 to 2022, building on a review published in 2013. We included randomised controlled trials that evaluated interventions that influence (decrease or increase) acute hospital admissions or attendances of long-term care facility residents. Risk of bias and evidence quality were assessed using Cochrane Risk Of Bias-2 and Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Forty-three randomised studies were included in this review. A narrative synthesis was conducted and the weight of evidence described with vote counting. Advance care planning and goals of care setting appear to be effective at reducing hospitalisations from long-term care facilities. Other effective interventions, in order of increasing risk of bias, were: nurse practitioner/specialist input, palliative care intervention, influenza vaccination and enhancing access to intravenous therapies in long-term care facilities. CONCLUSIONS: Factors that affect hospitalisation and emergency department attendances of long-term care facility residents are complex. This review supports the already established use of advance care planning and influenza vaccination to reduce unscheduled hospital attendances. It is likely that more than one intervention will be needed to impact on healthcare usage across the long-term care facility population. The findings of this review are useful to identify effective interventions that can be combined, as well as highlighting interventions that either need evaluation or are not effective at decreasing healthcare usage.

National Early Warning Scores Following Emergency Hospital Transfer: Implications for Care Home Residents.

OBJECTIVE: Care home residents have high rates of hospital admission. The UK National Early Warning Score (NEWS2) standardizes the secondary care response to acute illness. However, the ability of NEWS2 to predict adverse health outcomes specifically for care home residents is unknown. This study explored the relationship between NEWS2 on admission to hospital and resident outcome 7 days later. DESIGN: Repeated cross-sectional study. SETTING AND PARTICIPANTS: Data on UK care home residents admitted to 160 hospitals in two 24-hour periods (2019 and 2020). METHOD: Chi-squared and Kruskal-Wallis tests, and multinomial regression were used to explore the association between low (score ≤2), intermediate (3-4), high (5-6), and critically high (≥7) NEWS2 on admission and each of the following: discharge on day of admission, admission and discharge within 7 days, prolonged hospital admission (>7 days), and death. RESULTS: From 665 resident admissions across 160 hospital sites, NEWS2 was low for 54%, intermediate for 18%, high for 13%, and critically high for 16%. The 7-day outcome was 10% same-day discharge, 47% admitted and subsequently discharged, 34% remained inpatients, and 8% died. There is a significant association between NEWS2 and these outcomes (P < .001). Compared with those with low NEWS2, residents with high and critically high NEWS2 had 3.6 and 9.5 times increased risk of prolonged hospitalization [relative risk ratio (RRR) 3.56; 95% CI 1.02-12.37; RRR 9.47; CI 2.20-40.67], respectively. The risk of death was approximately 14 times higher for residents with high NEWS2 (RRR 13.62; CI 3.17-58.49) and 54 times higher (RRR 53.50; CI 11.03-259.54) for critically high NEWS2. CONCLUSION AND IMPLICATIONS: Higher NEWS2 measurements on admission are associated with an increased risk of hospitalization up to 7 days duration, prolonged admission, and mortality for care home residents. NEWS2 may have a role as an adjunct to acute care decision making for hospitalized residents.

NEWS2 and the older person.

The National Early Warning Score (NEWS), published in 2012, made no specific adjustments for older people. The updated NEWS2 (2017) incorporated new confusion as a category for consciousness. In this article, we consider the role of NEWS2 in detection of acute clinical deterioration in older people and how the score may be used to inform care, highlighting the additional aspects, such as care escalation decisions, that may ensue. We consider the evidence of NEWS and NEWS2 in assessment of the older person in different settings, including the potential benefits and limitations for care home residents. We suggest that NEWS2 may need adaptation for older people in future iterations, and that it should be used in conjunction with other clinical assessments, such as the Clinical Frailty Scale and the four 'A's test (4AT) for delirium.

NEWS2 in out-of-hospital settings, the ambulance and the emergency department.

As more healthcare is provided in non-hospital settings, it is essential to support clinicians in recognising early signs of clinical deterioration to enable prompt intervention and treatment.There are intuitive reasons why the use of the National Early Warning Score 2 (NEWS2) in out-of-hospital settings may enhance the community response to acute illness by using a common language across healthcare. An additional advantage of the use of NEWS2 in community settings is that it is not disease specific and requires no expensive technology or great expertise to take a full set of observations that can be an indicator of clinical acuity.However, concerns have been expressed as NEWS2 was developed in acute hospital settings that it may not be applicable in community settings; this review shares some of the practical ways that NEWS2 can support clinical practice along with the emerging published evidence.

National Early Warning Scores and COVID-19 deaths in care homes: an ecological time-series study.

OBJECTIVES: To investigate whether National Early Warning Scores (NEWS/NEWS2) could contribute to COVID-19 surveillance in care homes. SETTING: 460 care home units using the same software package to collect data on residents, from 46 local authority areas in England. PARTICIPANTS: 6464 care home residents with at least one NEWS recording. EXPOSURE MEASURE: 29 656 anonymised person-level NEWS from 29 December 2019 to 20 May 2020 with component physiological measures: systolic blood pressure, respiratory rate, pulse rate, temperature and oxygen saturation. Baseline values for each measure calculated using 80th and 20th centile scores before March 2020. OUTCOME MEASURE: Cross-correlation comparison of time series with Office for National Statistics weekly reported registered deaths of care home residents where COVID-19 was the underlying cause of death, and all other deaths (excluding COVID-19) up to 10 May 2020. RESULTS: Deaths due to COVID-19 were registered from 23 March 2020 in the local authority areas represented in the study. Between 23 March 2020 and 10 May 2020, there were 5753 deaths (1532 involving COVID-19 and 4221 other causes). We observed a rise in the proportion of above-baseline NEWS beginning 16 March 2020, followed 2 weeks later by an increase in registered deaths (cross-correlation of r=0.82, p<0.05 for a 2 week lag) in corresponding local authorities. The proportion of above-baseline oxygen saturation, respiratory rate and temperature measurements also increased approximately 2 weeks before peaks in deaths. CONCLUSIONS: NEWS could contribute to COVID-19 disease surveillance in care homes during the pandemic. Oxygen saturation, respiratory rate and temperature could be prioritised as they appear to signal rise in mortality almost as well as NEWS. This study reinforces the need to collate data from care homes, to monitor and protect residents' health. Further work using individual level outcome data is needed to evaluate the role of NEWS in the early detection of resident illness.

Experiences of a National Early Warning Score (NEWS) intervention in care homes during the COVID-19 pandemic: a qualitative interview study.

BACKGROUND: The COVID-19 pandemic has taken a heavy toll on the care home sector, with residents accounting for up to half of all deaths in Europe. The response to acute illness in care homes plays a particularly important role in the care of residents during a pandemic. Digital recording of a National Early Warning Score (NEWS), which involves the measurement of physical observations, started in care homes in one area of England in 2016. Implementation of a NEWS intervention (including equipment, training and support) was accelerated early in the pandemic, despite limited evidence for its use in the care home setting. OBJECTIVES: To understand how a NEWS intervention has been used in care homes in one area of North-East England during the COVID-19 pandemic, and how it has influenced resident care, from the perspective of stakeholders involved in care delivery and commissioning. METHODS: A qualitative interview study with care home (n=10) and National Health Service (n=7) staff. Data were analysed using thematic analysis. RESULTS: Use of the NEWS intervention in care homes in this area accelerated during the COVID-19 pandemic. Stakeholders felt that NEWS, and its associated education and support package, improved the response of care homes and healthcare professionals to deterioration in residents' health during the pandemic. Healthcare professionals valued the ability to remotely monitor resident observations, which facilitated triage and treatment decisions. Care home staff felt empowered by NEWS, providing a common clinical language to communicate concerns with external services, acting as an adjunct to staff intuition of resident deterioration. CONCLUSIONS: The NEWS intervention formed an important part of the care home response to COVID-19 in the study area. Positive staff perceptions now need to be supplemented with data on the impact on resident health and well-being, workload, and service utilisation, during the pandemic and beyond.

Changes in health and functioning of care home residents over two decades: what can we learn from population-based studies?

BACKGROUND: Care home residents have complex care and support needs. There is a perception that the needs of residents have increased, but the evidence is limited. We investigated changes in health and functioning of care home residents over two decades in England and Wales. METHODS: We conducted a repeated cross-sectional analysis over a 24 year period (1992-2016), using data from three longitudinal studies, the Cognitive Function and Ageing Studies (CFAS) I and II and the English Longitudinal Study of Ageing (ELSA). To adjust for ageing of respondents over time results are presented for the 75-84 age group. RESULTS: Analysis of 2,280 observations from 1,745 care home residents demonstrated increases in severe disability (difficulty in at least two from washing, dressing and toileting). The prevalence of severe disability increased from 63% in 1992 to 87% in 2014 (subsequent fall in 2016 although wide confidence intervals). The prevalence of complex multimorbidity (problems in at least three out of six body systems) increased within studies over time, from 33% to 54% in CFAS I/II between 1992 and 2012, and 26% to 54% in ELSA between 2006 and 2016. CONCLUSION: Over two decades, there has been an increase in disability and the complexity of health problems amongst care home residents in England and Wales. A rise in support needs for residents places increasing demands on care home staff and health professionals, and should be an important consideration for policymakers and service commissioners.

Commentary: COVID in care homes-challenges and dilemmas in healthcare delivery.

The COVID-19 pandemic has disproportionately affected care home residents internationally, with 19-72% of COVID-19 deaths occurring in care homes. COVID-19 presents atypically in care home residents and up to 56% of residents may test positive whilst pre-symptomatic. In this article, we provide a commentary on challenges and dilemmas identified in the response to COVID-19 for care homes and their residents. We highlight the low sensitivity of polymerase chain reaction testing and the difficulties this poses for blanket screening and isolation of residents. We discuss quarantine of residents and the potential harms associated with this. Personal protective equipment supply for care homes during the pandemic has been suboptimal and we suggest that better integration of procurement and supply is required. Advance care planning has been challenged by the pandemic and there is a need to for healthcare staff to provide support to care homes with this. Finally, we discuss measures to implement augmented care in care homes, including treatment with oxygen and subcutaneous fluids, and the frameworks which will be required if these are to be sustainable. All of these challenges must be met by healthcare, social care and government agencies if care home residents and staff are to be physically and psychologically supported during this time of crisis for care homes.
