ABSTRACT
BackgroundThe adoption of remote methods of care has been accelerated by the COVID-19 pandemic, but concerns exist relating to the potential impact on health disparities. This evaluation explores the implementation of COVID-19 remote home monitoring services across England, focussing on patients experiences and engagement with the service. MethodsThe study was a rapid, multi-site, mixed methods evaluation. Data were collected between January and June 2021. We conducted qualitative interviews with staff service leads, and patients and carers receiving the service. We conducted quantitative surveys with staff delivering the service, and patients and carers receiving the service across 28 sites in England, UK. Qualitative data were analysed using thematic analysis and quantitative data were analysed using univariate and multivariate methods. FindingsMany sites designed their service to be inclusive to the needs of their local population. Strategies included widening eligibility criteria, prioritising vulnerable groups, and creating referral pathways. Many sites also adapted their services according to patient needs, including providing information in different languages or more accessible formats, offering translation services, offering non-digital options, or providing face-to-face assessments. Despite these adaptions, disparities were reported across patient groups (e.g. age, health status, ethnicity, level of education) in their experience of and engagement with the service. InterpretationServices must determine how best to design and implement remote monitoring services to be of value to all populations. National guidance should play a role in supporting services to best serve the needs of their populations, and patients and staff must play an active role in service design.

Research in contextO_ST_ABSEvidence before this studyC_ST_ABSEvidence shows COVID-19 has a disproportionate impact on certain population groups, such as ethnic minority groups, older adults and those with comorbidities. The rapid adoption and spread of remote home monitoring services in England must be accompanied by evaluations at a local level to monitor the impact on health disparities in local populations. Added value of this studyThis rapid mixed methods evaluation of COVID-19 home monitoring services adopted across 28 sites in England aimed to increase understanding of how services have been designed and delivered to address local population needs to increase accessibility to the service and facilitate engagement with the service. We add to the literature by identifying a range of local service adaptations which aim to increase reach and facilitate patient engagement, and consider their potential impact on health disparities. We found strategies included prioritising vulnerable groups, creating referral pathways, offering translation services, offering non-digital options, or providing face-to-face assessments. Despite efforts to adapt services to meet local needs, disparities across patient groups in their experience of, and engagement with, the service (related to age, health status, ethnicity, and level of education) were reported. Implications of the available evidenceAt both a national and local level, and particularly given the increasing use of remote home monitoring schemes, lessening health disparities must be a primary focus in the design and delivery of remote monitoring models for COVID-19 and other conditions. Future research should focus on how best to design and evaluate remote monitoring services, for a range of conditions, especially for patients residing in areas where significant health disparities persist, as well as addressing the effectiveness of any strategies on specific population groups.
ABSTRACT
BackgroundThere was a national roll out of COVID Virtual Wards (CVW) during Englands second COVID-19 wave (Autumn 2020 - Spring 2021). These services used remote pulse oximetry monitoring for COVID-19 patients following discharge from hospital. A key aim was to enable rapid detection of patient deterioration. It was anticipated that the services would support early discharge and avoid readmissions, reducing pressure on beds. This study is an evaluation of the impact of the CVW services on hospital activity. MethodsUsing retrospective patient-level hospital admissions data, we built multivariate models to analyse the relationship between the implementation of CVW services and hospital activity outcomes: length of COVID-19 related stays and subsequent COVID-19 readmissions within 28 days. We used data from more than 98% of recorded COVID-19 hospital stays in England, where the patient was discharged alive between mid-August 2020 and late February 2021. FindingsWe found a longer length of stay for COVID-19 patients discharged from hospitals where a CVW was available, when compared to patients discharged from hospitals where there was no CVW (adjusted IRR 1{middle dot}05, 95% CI 1{middle dot}01 to 1{middle dot}09). We found no evidence of a relationship between the availability of CVW and subsequent rates of readmission for COVID-19 (adjusted OR 0{middle dot}95, 95% CI 0{middle dot}89 to 1{middle dot}02). InterpretationWe found no evidence of early discharges or reduced readmissions associated with the roll out of COVID Virtual Wards across England. Our analysis made pragmatic use of national-scale hospital data, but it is possible that a lack of specific data (for example, on which patients were enrolled) may have meant that true impacts, especially at a local level, were not ultimately discernible. FundingThis is independent research funded by the National Institute for Health Research, Health Services & Delivery Research programme and NHSEI. Research in contextO_ST_ABSEvidence before this studyC_ST_ABSPost-hospital virtual wards have been found to have a positive impact on patient outcomes when focussed on patients with specific diseases, for example those with heart disease. There has been less evidence of impact for more heterogenous groups of patients. While these services have been rolled out at scale in England, there has been little evidence thus far that post-hospital virtual wards (using pulse oximetry monitoring) have helped to reduce the length of stay of hospitalised COVID-19 patients, or rates of subsequent readmissions for COVID-19. Added value of this studyThis national-scale study provides evidence that the rollout of post-hospital discharge virtual ward services for COVID-19 patients in England did not reduce lengths of stay in hospital, or rates of readmission. Implications of all the available evidenceWhile there is currently an absence of evidence of positive impacts for COVID-19 patients discharged to a virtual ward, our study emphasises the need for quality data to be collected as part of future service implementation.
ABSTRACT
IntroductionRemote home monitoring models were implemented during the COVID-19 pandemic to shorten hospital length of stay, reduce unnecessary hospital admission, readmission and infection, and appropriately escalate care. Within these models, patients are asked to take and record readings and escalate care if advised. There is limited evidence on how patients and carers experience these services. This study aimed to evaluate patient experiences of, and engagement with, remote home monitoring models for COVID-19. MethodsA rapid mixed-methods study in England. We conducted a cross-sectional survey and interviews with patients and carers. Interview findings were summarised using rapid assessment procedures sheets and grouping data into themes (using thematic analysis). Survey data were analysed using descriptive statistics. ResultsWe received 1069 surveys (18% response rate) and conducted interviews with patients (n=59) and carers (n=3). Care relied on support from staff members, and family/friends. Patients and carers reported positive experiences and felt that the service and human contact reassured them and was easy to engage with. Yet, some patients and carers identified problems with engagement. Engagement was influenced by: patient factors such as health and knowledge, support from family/friends and staff, availability and ease-of-use of informational and material resources (e.g. equipment), and service factors. ConclusionRemote home monitoring models place responsibility on patients to self-manage symptoms in partnership with staff; yet many patients required support and preferred human contact (especially for identifying problems). Caring burden and experiences of those living alone, and barriers to engagement should be considered when designing and implementing remote home monitoring services. Patient or public contributionFor this evaluation, members of the study team met with service user and public members of the BRACE PPI group and Health and Care Panel and patient representatives from RSET in a series of workshops. These workshops informed study design, data collection tools, data interpretation and to discuss study dissemination for Phase 2. For example, patient facing documents, such as the consent form, topic guides, patient survey and patient information sheet were reviewed by this group. Additionally, PPI members helped to pilot patient surveys and interview guides with the research team. We also asked some members of the public to pilot the patient survey. Members of the PPI group were given the opportunity to comment on the manuscript. One PPI member commented on the manuscript and the manuscript was amended accordingly.
ABSTRACT
BackgroundRemote home monitoring of people testing positive for COVID-19 using pulse oximetry was implemented across England during the Winter of 2020/21 to identify falling blood oxygen saturation levels at an early stage. This was hypothesised to enable earlier hospital admission, reduce the need for intensive care and improve survival. This study is an evaluation of the clinical effectiveness of the pre-hospital monitoring programme, COVID oximetry @home (CO@h). MethodsWe analysed relationships at a geographical area level between the extent to which people aged 65 or over were enrolled onto the programme and outcomes over the period between November 2020 to February 2021 FindingsFor every 10% increase in coverage of the programme, mortality was reduced by 2% (95% confidence interval: -4% to 1%), admissions increased by 3% (-1% to 7%), in-hospital mortality fell by 3% (-8% to 3%) and lengths of stay increased by 1{middle dot}8% (-1{middle dot}2% to 4{middle dot}9%). None of these results are statistically significant. InterpretationThere are several possible explanations for our findings. One is that the CO@h did not have the hypothesised impact. Another is that the low rates of enrolment and incomplete data in many areas reduced the chances of detecting any impact that may have existed. Also, CO@h has been implemented in many different ways across the country and these may have had varying levels of effect.

Research in ContextO_ST_ABSEvidence before this studyC_ST_ABSExisting evidence before this study and the search strategy used to obtain this evidence has been published previously by the authors in a systematic review. Previous quantitative studies have assessed remote oximetry monitoring services for COVID-19 patients mostly at individual sites and focussed on their safety. However, their effectiveness has been little studied. This may reflect the challenges of identifying reliable counterfactuals during a rapidly evolving pandemic. Added value of this studyThis study is part of a wider mixed methods evaluation that followed the rapid implementation of remote monitoring across the English NHS during the Winter of 2020/21. It adds to the evidence of the effectiveness of such programmes at a national level. Implications of the available evidenceThere is some existing evidence that remote monitoring of COVID-19 patients can be locally effective although we have not been able to replicate such findings at a wider level. Missing data and lower coverage of the service than expected may have influenced our results, and the effectiveness of some local programmes could have been lost among the analysis of national data. Future implementation requires better data collection strategies which could be focussed within fewer local areas, and effective learning from areas that have achieved better population coverage.
