The effect of relative hypotension on 30-day mortality in older people receiving emergency care.

Research has observed increased mortality among older people attending the emergency department (ED) who had systolic pressure > 7 mmHg lower than baseline primary care values. This study aimed to (1) assess feasibility of identifying this 'relative hypotension' using readily available ED data, (2) externally validate the 7 mmHg threshold, and (3) refine a threshold for clinically important relative hypotension. A single-centre retrospective cohort study linked year 2019 data for ED attendances by people aged over 64 to hospital discharge vital signs within the previous 18 months. Frailty and comorbidity scores were calculated. Previous discharge ('baseline') vital signs were subtracted from initial ED values to give individuals' relative change. Cox regression analysis compared relative hypotension > 7 mmHg with mean time to mortality censored at 30 days. The relative hypotension threshold was refined using a fully adjusted risk tool formed of logistic regression models. Receiver operating characteristics were compared to NEWS2 models with and without incorporation of relative systolic. 5136 (16%) of 32,548 ED attendances were linkable with recent discharge vital signs. Relative hypotension > 7 mmHg was associated with increased 30-day mortality (HR 1.98; 95% CI 1.66-2.35). The adjusted risk tool (AUC: 0.69; sensitivity: 0.61; specificity: 0.68) estimated each 1 mmHg relative hypotension to increase 30-day mortality by 2% (OR 1.02; 95% CI 1.02-1.02). 30-day mortality prediction was marginally better with NEWS2 (AUC: 0.73; sensitivity: 0.59; specificity: 0.78) and NEWS2 + relative systolic (AUC: 0.74; sensitivity: 0.63; specificity: 0.75). Comparison of ED vital signs with recent discharge observations was feasible for 16% individuals. The association of relative hypotension > 7 mmHg with 30-day mortality was externally validated. Indeed, any relative hypotension appeared to increase risk, but model characteristics were poor. These findings are limited to the context of older people with recent hospital admissions.

What are the goals of care for older people living with frailty when they access urgent care? Are those goals attained? A qualitative view of patient and carer perspectives.

STUDY OBJECTIVE: Little is known of the goals of care of older people living with frailty when they access urgent care. Equally whether these goals are attained from a patient and carer perspective is often unclear. This qualitative study examined the views of older people living with frailty and their families in relation to specific episodes of urgent care, what they wanted to achieve and whether those goals were attained. METHODS: Semi-structured interviews with older people living with frailty and their families between Jan and July 2019. Patient and carer participants were recruited in three hospitals in England and interviewed following the urgent care episode. Interviews were audio-recorded, transcribed verbatim and analysed following the principles of the Framework approach. Results were validated by an older people's involvement group. RESULTS: Forty participants were interviewed either alone or jointly (24 patients and 16 carers), describing episodes of urgent care which started in ED for 28 patients. The goals of care for participants accessing emergency care were that their medical problem be diagnosed and resolved; information about tests and treatment be given to them and their relatives; they receive an appropriate well-planned discharge to their own home with support where needed and without readmission or re-attendance at ED; and that they retain mobility, function and normal activities. Participants perceived that many of these goals of care were not attained. CONCLUSIONS: Older people living with frailty have heterogeneous urgent care goals which require individual ascertainment. Identifying these goals of care early could result in improved attainment through person-centred care.

A systematic review and recommendations for prom instruments for older people with frailty in emergency care.

INTRODUCTION: The current service metrics used to evaluate quality in emergency care do not account for specific healthcare outcome goals for older people living with frailty. These have previously been classified under themes of 'Autonomy' and 'Functioning'. There is no person-reported outcome measure (PROM) for older people with frailty and emergency care needs. This study aimed to identify and co-produce recommendations for instruments potentially suitable for use in this population. METHODS: In this systematic review, we searched six databases for PROMs used between 2010 and 2021 by older people living with frailty receiving acute hospital care. Studies were reviewed against predefined eligibility criteria and appraised for quality using the COSMIN Risk of Bias checklist. Data were extracted to map instrument constructs against an existing framework of acute healthcare outcome goals. Instrument face and content validity were assessed by lay collaborators. Recommendations for instruments with potential emergency care suitability were formed through co-production. RESULTS: Of 9392 unique citations screened, we appraised the full texts of 158 studies. Nine studies were identified, evaluating nine PROMs. Quality of included studies ranged from 'doubtful' to 'very good'. Most instruments had strong evidence for measurement properties. PROMs mainly assessed 'Functioning' constructs, with limited coverage of 'Autonomy'. Five instruments were considered too burdensome for the emergency care setting or too specific for older people living with frailty. CONCLUSIONS: Four PROMs were recommended as potentially suitable for further validation with older people with frailty and emergency care needs: COOP/WONCA charts, EuroQol, McGill Quality of Life (Expanded), and Palliative care Outcome Scale.

What matters most in acute care: an interview study with older people living with frailty.

BACKGROUND: Healthcare outcome goals are central to person-centred acute care, however evidence among older people is scarce. Older people who are living with frailty have distinct requirements for healthcare delivery and have distinct risk for adverse outcomes from healthcare. There is insufficient evidence for whether those living with frailty also have distinct healthcare outcome goals. This study explored the nature of acute care outcome goals in people living with frailty. METHODS: Healthcare outcome goals were explored using semi-structured patient interviews. Participants aged over 65 with Clinical Frailty Score 5-8 (mild to very severe frailty) were recruited during their first 72 hours in a UK hospital. Purposive, maximum variation sampling was guided by lay partners from a Patient and Public Involvement Forum specialising in ageing-related research. Qualitative analysis used a blended approach based on framework and constant comparative methodologies for the identification of themes. Findings were validated through triangulation with participant, lay partner, and technical expert review. RESULTS: The 22 participants were aged 71 to 98 and had mild to very severe frailty. One quarter were living with dementia. Most participants had reflected on their situation and considered their outcome goals. Theme categories (and corresponding sub-categories) were 'Autonomy' (information, control, and security) and 'Functioning' (physical, psychosocial, and relief). A novel 'security' theme was identified, whereby participants sought to feel safe in their usual living place and with their health problems. Those living with milder frailty were concerned to maintain ability to support loved ones, while those living with most severe frailty were concerned about burdening others. CONCLUSIONS: Outcome goals for acute care among older participants living with frailty were influenced by the insecurity of their situation and fear of deterioration. Patients may be supported to feel safe and in control through appropriate information provision and functional support.

Emergency department management of older people living with frailty: a guide for emergency practitioners.

Emergency Departments (EDs) are increasingly seeing more seriously unwell older people living with frailty. In the context of limited resources and increasing demand it's the ED practitioner's challenge to unpick this constellation of physical, psychological, functional and social issues.To properly assess older people living with frailty at the ED it is crucial to use an holistic approach. This consists of triage with algorithms sensitive to the higher risk of older people living with frailty, a frailty assessment, and an assessment with the help of the principles of Comprehensive Geriatric Assessment. Multi-disciplinary care, a tailor-made treatment plan, based on what the person values most, will help the ED practitioner to deliver appropriate and valuable care during the ED stay, but also in transition from hospital to home.

Improving outcomes for older people in the emergency department: a review of reviews.

BACKGROUND: There has been a recognised trend of increasing use of emergency and urgent care and emergency departments (EDs) by older people, which is marked by a substantial evidence base reporting interventions for this population and guidance from key organisations. Despite this, outcomes for this population remain suboptimal. A plethora of reviews in this area provides challenges for clinicians and commissioners in determining which interventions and models of care best meet people's needs. The aim of this review was to identify effective ED interventions which have been reported for older people, and to provide a clear summary of the myriad reviews and numerous intervention types in this area. METHODS: A review of reviews, reporting interventions for older people, either initiated or wholly delivered within the ED. RESULTS: A total of 15 review articles describing 83 primary studies met our content and reporting standards criteria. The majority (n=13) were systematic reviews (four using meta-analysis.) Across the reviews, 26 different outcomes were reported with inconsistency. Follow-up duration varied within and across the reviews. Based on how authors had reported results, evidence clusters were developed: (1) staff-focused reviews, (2) discharge intervention reviews, (3) population-focused reviews and (4) intervention component reviews. CONCLUSIONS: The evidence base describing interventions is weak due to inconsistent reporting, differing emphasis placed on the key characteristics of primary studies (staff, location and outcome) by review authors and varying quality of reviews. No individual interventions have been found to be more promising, but interventions initiated in the ED and continued into other settings have tended to result in more favourable patient and health service outcomes. Despite many interventions reported within the reviews being holistic and patient focused, outcomes measured were largely service focused. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42018111461.

Hyperkinetic reaction to dihydrocodeine.

A young man was using dihydrocodeine analgesia for ear pain having had suppurative otitis media. He attended the emergency department with restlessness and twitching movements in his arms and legs. He had fever with otherwise normal vital signs. He had no signs of cerebellar pathology. Investigations were normal. The working diagnosis was of hyperkinetic reaction to dihydrocodeine. Symptoms resolved within 48 hours of withdrawing the drug. Serotonin toxicity is a rare side effect of dihydrocodeine. There is a theoretical basis for increased side effects when taken with cannabidiol-based substances.

What older people want from emergency care: a systematic review.

OBJECTIVES: To evaluate the expectations and preferred outcomes from emergency care among older people or their caregivers. METHODS: A review protocol was registered. Medline, Embase, CINAHL, PsychInfo, BNI, AgeInfo and the Cochrane Database of Systematic Reviews were searched in their full date ranges to September 2018. Included articles were hand-searched for further citations. Citations were screened for (1) older people aged over 65 years, (2) ED settings and (3) reporting expectations or preferred outcomes for emergency care (as opposed to experience or satisfaction). Quality appraisal and data extraction of eligible articles were undertaken by two reviewers. Themes were synthesised through content analysis and described narratively. RESULTS: Older people wished to have prompt waiting times, efficient care, clear communication and comfortable environments. They had additional and unique expectations for holistic care and support in decision-making. The ED provoked a sense of vulnerability among older people who were likely to have had frailty. CONCLUSION: The lack of dominant themes among included studies suggests that older people should be treated as individuals rather than a homogenous group. Establishing individuals' preferred outcomes could improve person-centred care. PROSPERO REGISTRATION NUMBER: CRD42018107050.

The Acute Frailty Network: experiences from a whole-systems quality improvement collaborative for acutely ill older patients in the English NHS.

Older people form a growing proportion and volume of those accessing urgent care, much of which is provided by non-specialists in geriatric medicine. Non-specific presentations, multiple comorbidities and functional decline make assessment and management of this cohort challenging. In this article we describe the approach and methods of the Acute Frailty Network (AFN), a national quality improvement collaborative designed to support acute hospitals in England to deliver evidence-based care for older people with frailty. We report on 3 years' experience of whole-systems quality improvement through the network. Using local case studies, we illustrate initiatives through which AFN hospitals improved services and outcomes for older people with frailty and urgent care needs. We describe returns on investment and sustainability of implementation, and reflect on future directions for the AFN.
