Virtual wards: a rapid evidence synthesis and implications for the care of older people

From challenges to opportunities: Digital transformation in hospital-at-home care

BACKGROUND

Digital transformation is an ongoing sosio-technological process that can create opportunities in the health sector. However, the current landscape of digital transformation in hospital-at-home care is unknown.

AIM

To describe healthcare providers' perspectives of digital transformation in hospital-at-home care.

METHODS

A total of 25 semi-structured interviews were conducted in September-October 2023 in all Finnish wellbeing services counties (n = 21), the city of Helsinki (n = 1), and private health care providers (n = 3). Snowball sampling was used (N = 46). The data underwent an inductive content analysis.

RESULT

The analysis revealed four main and 17 generic categories of challenges and opportunities of digital transformation in hospital-at-home care. These challenges and opportunities were related to 1) Health information exchange in and across hospital-at-home care; 2) Management of hospital-at-home care; 3) Logistics in hospital-at-home care planning and delivery; and 4) Digital health interventions in hospital-at-home care delivery.

CONCLUSIONS

The challenges and opportunities of digital transformation in the hospital-at-home care is intricately linked to the efficiency of health information exchange, management, logistics, and digital health interventions. Addressing the key areas of improvement in health information exchange can lead to more streamlined patient care processes and improved communication between healthcare professionals and patients. Digital transformation in management and logistics can improve overall efficiency within healthcare systems. Digital health interventions may promote equitable and universal access to high-quality healthcare. Continued focus on health care information infrastructure, in particular interoperability of electronic health records and optimization of information flow, will be essential to realize the full potential of digitalization.

Discharge Against Medical Advice: The Causes, Consequences and Possible Corrective Measures

Patients who discharge themselves against medical advice comprise 1%-2% of hospital admissions. Discharge against medical advice (DAMA) is defined as when a hospitalised patient chooses to leave the hospital before the treating medical team recommends discharge. The act of DAMA impacts on both the patient, the staff and their ongoing care. Specifically, this means that the patient's medical problems maybe inadequately assessed or treated. Patients who decide to DAMA tend to be young males, from a lower socioeconomic background and with a history of mental health or substance misuse disorder. DAMA has an associated increased risk of morbidity and mortality. In this review of studies across Western healthcare settings, specifically adult medical inpatients, we will review the evidence and seek to address the causes, consequences and possible corrective measures in this common scenario.

Telehealth-aided outpatient management of acute heart failure in a specialist virtual ward compared with standard care

AIMS

The aim of this propensity score matched cohort study was to assess the outcomes of telehealth-guided outpatient management of acute heart failure (HF) in our virtual ward (HFVW) compared with hospitalized acute HF patients.

METHODS AND RESULTS

This cohort study (May 2022-October 2023) assessed outcomes of telehealth-guided outpatient acute HF management using bolus intravenous furosemide in a HF-specialist VW. Propensity score matching (PSM) was performed using logistic regression to adjust for potential differences in baseline patient characteristics between HFVW and standard care [Get With The Guidelines-HF score, clinical frailty score (CFS), Charlson co-morbidity index (CCI), NT-proBNP, and ejection fraction]. Clinical outcomes (re-hospitalizations and mortality) were compared at 1, 3, 6, and 12 months versus standard care-SC (acute HF patients managed without telehealth in 2021). Five hundred fifty-four HFVW ADHF patients (age 73.1 ± 10.9 years; 46% female) were compared with 404 ADHF patients (74.2 ± 11.8; P = 0.15 and 49% female) in the standard care-SC cohort. After propensity score matching for baseline patient characteristics, re-hospitalizations were significantly lower in the HFVW compared with SC (1 month-HFVW 8.6% vs. SC-21.5%, P < 0.001; 3 months-21% vs. 30%, P = 0.003; 6 months-28% vs 41%, P < 0.001 and 12 months-47% vs. 57%, P = 0.005) and mortality was also lower at 1 month (5% vs. 13.7%; P < 0.001), 3 months (9.5% vs. 15%; P = 0.001), 6 months (15% vs. 21%; P = 0.03), and 12 months (20% vs. 26%; P = 0.04). Multivariate logistic regression analysis showed that compared with standard care, HFVW management was associated with lower odds of readmission (1-month odds ratio (OR) = 0.3 [95% Confidence Interval CI 0.2-0.5], P < 0.0001; 3 month OR = 0.15 [0.1-0.3], P < 0.0001; 6-month OR = 0.35 [0.2-0.6], P = 0.0002; 12-month OR = 0.25 [0.15-0.4], P ≤ 0.001 and mortality (1-month OR = 0.26 [0.14-0.48], P < 0.0001; 3-month OR = 0.11 [0.04-0.27], P < 0.0001; 6-month OR = 0.35, [0.2; 0.61], P = 0.0002; 12-month OR = 0.6 [0.48; 0.73], P = 0.03. Higher GWTG-HF score independently predicted increased odds of re-hospitalization (1-month OR = 1.2 [1.1-1.3], P < 0.001; 3-month OR = 1.5 [1.37; 1.64], P < 0.0001; 6-month OR = 1.3 [1.2-1.4], P < 0.0001; 12-month OR = 1.1 [1.05-1.2], P = 0.03) as well as mortality (1-month OR = 1.21 [1.1-1.3], P < 0.0001; 3-month OR = 1.3 [1.2-1.4], P < 0.0001; 6-month OR = 1.2 [1.1-1.3], P < 0.0001; 12-month OR = 1.3 [1.1-1.7], P = 0.02). Similarly higher CFS also independently predicted increased odds of re-hospitalizations (1-month OR = 1.9 [1.5-2.4], P < 0.0001; 3-month OR = 1.8 [1.3-2.4], P = 0.0003; 6-month OR = 1.4 [1.1-1.8], P = 0.015; 12-month OR 1.9 [1.2-3], P = 0.01]) and mortality (1-month OR = 2.1 [1.6-2.8], P < 0.0001; 3-month OR = 1.8 [1.2-2.6], P = 0.006; 6-month OR = 2.34 [1.51-5.6], P = 0.0001; 12-month OR = 2.6 [1.6-7], P = 0.02). Increased daily step count while on HFVW independently predicted reduced odds of re-hospitalizations (1-month OR = 0.85[0.7-0.9], P = 0.005), 3-month OR = 0.95 [0.93-0.98], P = 0.003 and 1-month mortality (OR = 0.85 [0.7-0.95], P = 0.01), whereas CCI predicted adverse 12-month outcomes (OR = 1.2 [1.1-1.4], P = 0.03).

CONCLUSIONS

Telehealth-guided specialist HFVW management for ADHF may offer a safe and efficacious alternative to hospitalization in suitable patients. Daily step count in HFVW can help predict risk of short-term adverse clinical outcomes.

Remote Vital Sign Monitoring in Admission Avoidance Hospital at Home: A Systematic Review

OBJECTIVES

To examine randomized controlled trials (RCTs) of "hospital at home" (HAH) for admission avoidance in adults presenting with acute physical illness to identify the use of vital sign monitoring approaches and evidence for their effectiveness.

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

This review compared strategies for vital sign monitoring in admission avoidance HAH for adults presenting with acute physical illness. Vital sign monitoring can support HAH acute multidisciplinary care by contributing to safety, determining requirement of further assessment, and guiding clinical decisions. There are a wide range of systems currently available, including reliable and automated continuous remote monitoring using wearable devices.

METHODS

Eligible studies were identified through updated database and trial registries searches (March 2, 2016, to February 15, 2023), and existing systematic reviews. Risk of bias was assessed using the Cochrane risk of bias 2 tool. Random effects meta-analyses were performed, and narrative summaries provided stratified by vital sign monitoring approach.

RESULTS

Twenty-one eligible RCTs (3459 participants) were identified. Two approaches to vital sign monitoring were characterized: manual and automated. Reporting was insufficient in the majority of studies for classification. For HAH compared to hospital care, 6-monthly mortality risk ratio (RR) was 0.94 (95% CI 0.78-1.12), 3-monthly readmission to hospital RR 1.02 (0.77-1.35), and length of stay mean difference 1.91 days (0.71-3.12). Readmission to hospital was reduced in the automated monitoring subgroup (RR 0.30 95% CI 0.11-0.86).

CONCLUSIONS AND IMPLICATIONS

This review highlights gaps in the reporting and evidence base informing remote vital sign monitoring in alternatives to admission for acute illness, despite expanding implementation in clinical practice. Although continuous vital sign monitoring using wearable devices may offer added benefit, its use in existing RCTs is limited. Recommendations for the implementation and evaluation of remote monitoring in future clinical trials are proposed.

New horizons in clinical practice guidelines for use with older people

Globally, more people are living into advanced old age, with age-associated frailty, disability and multimorbidity. Achieving equity for all ages necessitates adapting healthcare systems. Clinical practice guidelines (CPGs) have an important place in adapting evidence-based medicine and clinical care to reflect these changing needs. CPGs can facilitate better and more systematic care for older people. But they can also present a challenge to patient-centred care and shared decision-making when clinical and/or socioeconomic heterogeneity or personal priorities are not reflected in recommendations or in their application. Indeed, evidence is often lacking to enable this variability to be reflected in guidance. Evidence is more likely to be lacking about some sections of the population. Many older adults are at the intersection of many factors associated with exclusion from traditional clinical evidence sources with higher incidence of multimorbidity and disability compounded by poorer healthcare access and ultimately worse outcomes. We describe these challenges and illustrate how they can adversely affect CPG scope, the evidence available and its summation, the content of CPG recommendations and their patient-centred implementation. In all of this, we take older adults as our focus, but much of what we say will be applicable to other marginalised groups. Then, using the established process of formulating a CPG as a framework, we consider how these challenges can be mitigated, with particular attention to applicability and implementation. We consider why CPG recommendations on the same clinical areas may be inconsistent and describe approaches to ensuring that CPGs remain up to date.

Hospital Staff Perspectives on the Drivers and Challenges in Implementing a Virtual Rehabilitation Ward: Qualitative Study

Background

Over the past decade, the adoption of virtual wards has surged. Virtual wards aim to prevent unnecessary hospital admissions, expedite home discharge, and enhance patient satisfaction, which are particularly beneficial for the older adult population who faces risks associated with hospitalization. Consequently, substantial investments are being made in virtual rehabilitation wards (VRWs), despite evidence of varying levels of success in their implementation. However, the facilitators and barriers experienced by virtual ward staff for the rapid implementation of these innovative care models remain poorly understood.

Objective

This paper presents insights from hospital staff working on an Australian VRW in response to the growing demand for programs aimed at preventing hospital admissions. We explore staff's perspectives on the facilitators and barriers of the VRW, shedding light on service setup and delivery.

Methods

Qualitative interviews were conducted with 21 VRW staff using the Nonadoption, Abandonment, Scale-up, Spread, and Sustainability (NASSS) framework. The analysis of data was performed using framework analysis and the 7 domains of the NASSS framework.

Results

The results were mapped onto the 7 domains of the NASSS framework. (1) Condition: Managing certain conditions, especially those involving comorbidities and sociocultural factors, can be challenging. (2) Technology: The VRW demonstrated suitability for technologically engaged patients without cognitive impairment, offering advantages in clinical decision-making through remote monitoring and video calls. However, interoperability issues and equipment malfunctions caused staff frustration, highlighting the importance of promptly addressing technical challenges. (3) Value proposition: The VRW empowered patients to choose their care location, extending access to care for rural communities and enabling home-based treatment for older adults. (4) Adopters and (5) organizations: Despite these benefits, the cultural shift from in-person to remote treatment introduced uncertainties in workflows, professional responsibilities, resource allocation, and intake processes. (6) Wider system and (7) embedding: As the service continues to develop to address gaps in hospital capacity, it is imperative to prioritize ongoing adaptation. This includes refining the process of smoothly transferring patients back to the hospital, addressing technical aspects, ensuring seamless continuity of care, and thoughtfully considering how the burden of care may shift to patients and their families.

Conclusions

In this qualitative study exploring health care staff's experience of an innovative VRW, we identified several drivers and challenges to implementation and acceptability. The findings have implications for future services considering implementing VRWs for older adults in terms of service setup and delivery. Future work will focus on assessing patient and carer experiences of the VRW.

Service innovations for people with multiple long-term conditions: reflections of a rapid evaluation team

Background

People living with multiple long-term conditions represent a significant concern for National Health Service policy and practice, and their care is a major theme in the 2019 National Health Service Long Term Plan. The Birmingham RAND and Cambridge Rapid Evaluation Centre team has undertaken a thematic synthesis of the 10 evaluations it has conducted from 2018 to 2023, exploring the needs, priorities and implications for people with multiple long-term conditions.

Objectives

The aims for this overarching study were to: (1) build a body of learning about service innovations in primary and community settings for people of all ages with multiple long-term conditions, focused on questions that matter most to people with multimorbidity; and (2) develop methodological insights about how rapid evaluation can be used to inform the scoping, testing and implementation of service innovations for people with multiple long-term conditions.

Design

The focus on multiple long-term conditions came from a Birmingham RAND and Cambridge Rapid Evaluation Centre prioritisation process undertaken in 2018 using James Lind Alliance methods. Cross-analysis of the findings from the 10 individual rapid evaluations was supplemented by (1) building aspects of multimorbidity into the design of later evaluations; (2) interviewing national and regional stakeholders (n=19) working in or alongside integrated care systems; (3) undertaking a rapid review of evidence on remote monitoring for people with multiple long-term conditions (19 papers included); and (4) testing overall insights with organisations representing patients and carers through a patient, public and professional engagement workshop with 10 participants plus members of the research team.

Results

While living with multiple long-term conditions is common and is the norm for people over the age of 50 using health and care services, it is not often a focus of health service provision or innovation, nor of research and evaluation activity. We discuss six themes emerging from the totality of the study: (1) our health system is mainly organised around single conditions and not multiple long-term conditions; (2) research calls and studies usually focus on single conditions and associated services; (3) building opportunities for engaged, informed individuals and carers and improved self-management; (4) the importance of measures that matter for patients and carers; (5) barriers to developing and implementing service innovations for people with multiple long-term conditions; and (6) what is needed to make patients with multiple long-term conditions a priority in healthcare planning and delivery.

Limitations

Care of people with multiple long-term conditions was not the principal focus of several of the rapid evaluations. While this was a finding in itself, it limited our learning about designing and implementing, as well as methodological approaches to evaluating, service innovations for people with multiple long-term conditions.

Conclusions

Through a thematic analysis of the portfolio of evaluations, we have deduced a set of suggested implications for how the needs of people with multiple long-term conditions can be better embedded in policy, research and practice.

Future work

Areas of uncertainty related to the care of people with multiple long-term conditions should be further explored, including developing and testing measures of patient experience of (un)co-ordinated care across settings, and interrogating the experience of health and care staff when working with people with multiple long-term conditions, to understand what works.

Transforming health care: Investigating Influenzer, a novel telemedicine-supported early discharge program for patients with lower respiratory tract infection: A non-randomized feasibility study

BACKGROUND

The COVID-19 pandemic has posed unprecedented challenges to healthcare systems globally, necessitating innovative care models like hospital-at-home and virtual care programs. The Influenzer telemedicine program aims to deliver hospital-led monitoring and treatment to patients at home. Integrating telemedicine technology with domestic visits provides an alternative to traditional hospitalization, with the aim of easing the burden on healthcare facilities without compromising patient safety. To evaluate the effectiveness of the Influenzer program, a randomized controlled trial is proposed. This study aimed to assess the feasibility of the proposed clinical trial design.

METHODS

A non-randomized feasibility study was conducted at the Department of Pulmonary and Infectious Diseases at Nordsjaellands Hospital offering a telemedicine-supported early discharge program to patients with lower respiratory tract infections, including COVID-19. The feasibility of trial procedures, including recruitment, adherence, and retention, was analyzed. Also, participants' characteristics and trajectory during the intervention, including telemedicine and domestic services, were assessed.

RESULTS

Nineteen patients were enrolled from June 2022 to April 2023 and treated at home. Forty patients were not enrolled as 15 (25%) were non-eligible according to study protocol, 15 (25%) refused to participate and 10 (17%) had not been approached. Subjects treated at home had comparable clinical outcomes to those treated in the acute hospital, no major safety incidences occurred and patients were highly satisfied. Participants demonstrated 99% adherence to planned daily monitoring activities. In total, 63% completed all survey assessments at least partially including baseline, at discharge, and 3 months post-discharge, while 89% participated in a follow-up interview. No participants withdrew their consent.

CONCLUSIONS

The feasibility study documented that the Influenzer home-hospital program was feasible and well accepted in a Scandinavian setting in terms of no withdrawals and excellent participant adherence to the planned daily monitoring activities. Challenges in the organizational structures including patient recruitment and data collection required resolution prior to our randomized clinical trial. Insights from this feasibility study have led to the improved design of the final Influenzer program evaluation trial.

Inpatient-level care at home delivered by virtual wards and hospital at home: a systematic review and meta-analysis of complex interventions and their components

BACKGROUND

Technology-enabled inpatient-level care at home services, such as virtual wards and hospital at home, are being rapidly implemented. This is the first systematic review to link the components of these service delivery innovations to evidence of effectiveness to explore implications for practice and research.

METHODS

For this review (registered here https://osf.io/je39y ), we searched Cochrane-recommended multiple databases up to 30 November 2022 and additional resources for randomised and non-randomised studies that compared technology-enabled inpatient-level care at home with hospital-based inpatient care. We classified interventions into care model groups using three key components: clinical activities, workforce, and technology. We synthesised evidence by these groups quantitatively or narratively for mortality, hospital readmissions, cost-effectiveness and length of stay.

RESULTS

We include 69 studies: 38 randomised studies (6413 participants; largely judged as low or unclear risk of bias) and 31 non-randomised studies (31,950 participants; largely judged at serious or critical risk of bias). The 69 studies described 63 interventions which formed eight model groups. Most models, regardless of using low- or high-intensity technology, may have similar or reduced hospital readmission risk compared with hospital-based inpatient care (low-certainty evidence from randomised trials). For mortality, most models had uncertain or unavailable evidence. Two exceptions were low technology-enabled models that involve hospital- and community-based professionals, they may have similar mortality risk compared with hospital-based inpatient care (low- or moderate-certainty evidence from randomised trials). Cost-effectiveness evidence is unavailable for high technology-enabled models, but sparse evidence suggests the low technology-enabled multidisciplinary care delivered by hospital-based teams appears more cost-effective than hospital-based care for those with chronic obstructive pulmonary disease (COPD) exacerbations.

CONCLUSIONS

Low-certainty evidence suggests that none of technology-enabled care at home models we explored put people at higher risk of readmission compared with hospital-based care. Where limited evidence on mortality is available, there appears to be no additional risk of mortality due to use of technology-enabled at home models. It is unclear whether inpatient-level care at home using higher levels of technology confers additional benefits. Further research should focus on clearly defined interventions in high-priority populations and include comparative cost-effectiveness evaluation.

Virtual wards for people with frailty: what works, for whom, how and why-a rapid realist review

BACKGROUND

Virtual wards (VWs) deliver multidisciplinary care at home to people with frailty who are at high risk of a crisis or in crisis, aiming to mitigate the risk of acute hospital admission. Different VW models exist, and evidence of effectiveness is inconsistent.

AIM

We conducted a rapid realist review to identify different VW models and to develop explanations for how and why VWs could deliver effective frailty management.

METHODS

We searched published and grey literature to identify evidence on multidisciplinary VWs. Information on how and why VWs might 'work' was extracted and synthesised into context-mechanism-outcome configurations with input from clinicians and patient/public contributors.

RESULTS

We included 17 peer-reviewed and 11 grey literature documents. VWs could be short-term and acute (1-21 days), or longer-term and preventative (typically 3-7 months). Effective VW operation requires common standards agreements, information sharing processes, an appropriate multidisciplinary team that plans patient care remotely, and good co-ordination. VWs may enable delivery of frailty interventions through appropriate selection of patients, comprehensive assessment including medication review, integrated case management and proactive care. Important components for patients and caregivers are good communication with the VW, their experience of care at home, and feeling involved, safe and empowered to manage their condition.

CONCLUSIONS

Insights gained from this review could inform implementation or evaluation of VWs for frailty. A combination of acute and longer-term VWs may be needed within a whole system approach. Proactive care is recommended to avoid frailty-related crises.

Length of stay and economic sustainability of virtual ward care in a medium-sized hospital of the UK: a retrospective longitudinal study

OBJECTIVE

To evaluate the length of stay difference and its economic implications between hospital patients and virtual ward patients.

DESIGN

Retrospective longitudinal study.

SETTING

Wrightington, Wigan and Leigh (WWL) Teaching Hospitals, National Health Service (NHS) Foundation Trust, a medium-sized NHS trust in the north-west of England.

PARTICIPANTS

Virtual ward patients (n=318) were matched 1:1 to 1:4, depending on matching characteristics, to all hospital patients (n=350). All patients were admitted to the hospital during the calendar year 2022.

OUTCOME MEASURES

The primary outcome is the length of stay as defined from the date of hospital admission to the date of discharge or death (hospital patients) and from the date of hospital admission to the date of admission in a virtual ward (virtual ward patients). The secondary outcome is the cost of a hospital bed day and the equivalent value of virtual ward savings in hospital bed days. Additional measures were 6-month readmission rates and survival rates at the follow-up date of 30 April 2023.

RISK FACTORS

Age, sex, comorbidities and the clinical frailty score (CFS) were used to evaluate the importance and effect of these factors on the main and secondary outcomes.

METHODS

Statistical analyses included logistic and binomial mixed models for the length of stay in the hospital and readmission rate outcomes, as well as a Cox proportional hazard model for the survival of the patients.

RESULTS

The virtual ward patients had a shorter stay in the hospital before being admitted to the virtual ward (2.89 days, 95% CI 2.1 to 3.9 days). Chronic kidney disease (CKD) and frailty were associated with a longer length of stay in the hospital (58%, 95% CI 22% to 100%) compared with patients without CKD, and 14% (95% CI 8% to 21%) compared with patients with one unit lower CFS. The frailty score was also associated with a higher rate of readmission within 6 months and lower survival. Being admitted to the virtual ward slightly improved survival, although when readmitted, survival deteriorated rapidly. The cost of a 24-hour period in a general hospital bed is £536. The cost of a day hospital saved by a virtual ward was £935.

CONCLUSION

The use of a 40-bed virtual ward was clinically effective in terms of survival for patients not needing readmission and allowed for the freeing of three hospital beds per day. However, the cost for each day freed from hospital stay was three-quarters larger than the one for a single-day hospital bed. This raises concerns about the deployment of large-scale virtual wards without the existence of policies and plans for their cost-effective management.

Seeing the forest (plot) for the trees-the importance of evidence synthesis in older adult care

Systematically reviewing all the available evidence and then creating summary analyses of the pooled data is the foundation of evidence-based practice. Indeed, this evidence synthesis approach informs much of the care of older adults in hospital and community. It is perhaps no surprise that the journal Age and Ageing is a frequent platform for publishing research papers based on systematic review and synthesis. This research has evolved substantially from the early days of evidence-based medicine and the Cochrane Collaboration. The traditional approach would be a quantitative summary, calculated using pair-wise meta-analysis of randomised controlled trials of drug versus placebo, or a synthesis of observational studies to create summaries of prevalence, associations and outcomes. Methods have evolved and newer techniques such as scoping reviews, test accuracy meta-analysis and qualitative synthesis are all now available. The sophistication of these methods is driven in part by the increasingly complex decisions that need be made in contemporary older adult care. Age and Ageing continues to champion established and novel evidence synthesis approaches, and in the accompanying Collection exemplars of these differing methods are presented and described. Whilst there is marked heterogeneity in the techniques used, the consistent and defining feature of all these papers is the desire to comprehensively, and critically summarise the evidence in order to answer the most pertinent questions regarding older adult care.
