RESUMEN

BACKGROUND: Intervention fidelity in health services research has been poor with a reported lack of understanding about what constitutes pragmatic adaptation of interventions and what constitutes failure to maintain intervention fidelity. However, the challenges facing those delivering such interventions have not been thoroughly explored. The aims of this study were to critically explore the challenges in maintaining fidelity experienced by physiotherapy staff and support workers when delivering a complex intervention for older people living with frailty. METHODS: This study is a secondary analysis of data from a process evaluation of a large randomised controlled trial (RCT). The process evaluation employed qualitative methodologies with mixed methods including a variety of data collection methods, including participant observation, semi-structured interviews and documentary analysis. Thematic analysis was used to make sense of the data. RESULTS: Many therapy staff felt ongoing confusion about what was acceptable to adapt and what needed to follow the protocol exactly. We found that some therapy staff were able to embrace the challenges of pragmatically adapting interventions while maintaining intervention fidelity, others stuck rigidly to the protocol and failed to adapt interventions where it was necessary. CONCLUSION: It was clear that the understanding of fidelity and pragmatism was poor. While pragmatic trials are vital to replicate real world clinical practice, further guidance may need to be developed in order to guide the level of adaptation that is acceptable before fidelity is undermined.

RESUMEN

BACKGROUND: There are many consequences of lower limb amputation, including altered biomechanics of gait. It has previously been shown that these can lead to increased rates of osteoarthritis (OA). A common and successful treatment for severe OA is joint replacement. However, it is unclear whether amputees undergoing this surgery can expect the same outcomes or complication profile compared with non-amputees. Furthermore, there are key technical challenges associated with hip or knee replacement in lower limb amputees. This scoping review aimed to identify and summarise the existing evidence base. METHODS: This was a systematic scoping review performed according to PRISMA guidelines. An electronic database search of MEDLINE (PubMed), Cochrane Library, EMBASE and CINAHL was completed from the date of inception to 1st April 2023. All peer reviewed literature related to hip or knee replacement among lower limb amputees was included. RESULTS: Of the 931 records identified, 40 studies were included in this study. The available literature consisted primarily of case reports and case series, with generally low level of evidence. In total, there were 265 patients of which 195 received total hip replacement (THR), 51 received total knee replacement (TKR) and 21 received hip hemiarthroplasty. The most common reason for amputation was trauma (34.2%), and the main indication for joint replacement was OA (77.1%), occurring more frequently in the contralateral limb (66.7%). The outcomes reported varied widely between studies, with most suggesting good functional status post-operatively. A variety of technical tips were reported, primarily concerned with intra-operative control of the residual limb. CONCLUSION: There is a need for more observational studies to clearly define the association between amputation and subsequent need for joint replacement. Furthermore, comparative studies are needed to identify whether amputees can be expected to achieve similar functional outcomes after surgery, and if they are at higher risk of certain complications.

RESUMEN

OBJECTIVE: With advancing age comes the increasing prevalence of frailty and increased risk of adverse outcomes (eg, hospitalisation). Evidence for comprehensive geriatric assessment (CGA), a multidimensional holistic model of care, is mixed in community settings. Uncertainties remain, such as the key components of CGA, who delivers it, and the use of technology. This study aimed to understand the perspectives, beliefs and experiences, of both older people and health professionals, to improve the current CGA and explore factors that may impact on CGA delivery in community settings. DESIGN: A qualitative interview study was conducted with older people and healthcare professionals (HCPs) identified using a maximum variation strategy. Data were analysed using an abductive analysis approach. The non-adoption, abandonment, scale-up, spread and sustainability framework and the theoretical framework of acceptability guided the categorisation of the codes and identified categories were mapped to the two frameworks. SETTING: England, UK. RESULTS: 27 people were interviewed, constituting 14 older people and 13 HCPs. We identified limitations in the current CGA: a lack of information sharing between different HCPs who deliver CGA; poor communication between older people and their HCPs and a lack of follow-up as part of CGA. When we discussed the potential for CGA to use technology, HCPs and older people varied in their readiness to engage with it. CONCLUSIONS: Viable solutions to address gaps in the current delivery of CGA include the provision of training and support to use digital technology and a designated comprehensive care coordinator. The next stage of this research will use these findings, existing evidence and stakeholder engagement, to develop and refine a model of community-based CGA that can be assessed for feasibility and acceptability.

RESUMEN

INTRODUCTION: Individuals with dementia face an increased risk of falls. Falls can cause a decline in the individual's overall functionality. All types of falls, including those that do not result in injury, can lead to psychosocial consequences, such as diminished confidence and a fear of falling. Projections indicate a rising trend in dementia diagnoses, implying an increase in fall incidents. Yet, there is a lack of evidence to support interventions for people living with dementia who have fallen. Our objective is to test the feasibility of a falls intervention trial for people with dementia. METHOD AND ANALYSIS: This is a UK-based two-arm pilot cluster randomised controlled trial. In this study, six collaborating sites, which form the clusters, will be randomly allocated to either the intervention arm or the control arm (receiving treatment as usual) at a 1:1 ratio. During the 6 month recruitment phase, each cluster will enrol 10 dyads, comprising 10 individuals with dementia and their respective carers, leading to a total sample size of 60 dyads. The primary outcomes are the feasibility parameters for a full trial (ie, percentage consented, follow-up rate and cost framework). Secondary outcomes include activities of daily living, quality of life, fall efficacy, mobility, goal attainment, cognitive status, occurrence of falls, carer burden and healthcare service utilisation. Outcome measures will be collected at baseline and 28 weeks, with an additional assessment scheduled at 12 weeks for the healthcare service utilisation questionnaire. An embedded process evaluation, consisting of interviews and observations with participants and healthcare professionals, will explore how the intervention operates and the fidelity of study processes. ETHICS AND DISSEMINATION: The study was approved by the NHS and local authority research governance and research ethics committees (NHS REC reference: 23/WA/0126). The results will be shared at meetings and conferences and will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN16413728.

RESUMEN

BACKGROUND AND OBJECTIVES: Understanding how older people experience independence has implications for person-centered care. Existing understanding of older people's experience of independence, generated through methods that provide a "snapshot" view of a person's independence at a given time point, provides little insight into the process of maintaining independence through time. The aim of this study was to explore older participants' perceptions to understand the processes and resources that were most important for maintaining independence. RESEARCH DESIGN AND METHODS: Two semistructured interviews were conducted longitudinally to explore the perspectives of 12 community-dwelling, older people, aged 76-85 years. A social constructivist approach, using dramaturgical and descriptive codes, facilitated the interpretation of the data. Sixteen analytical questions guided the exploration of participants' perceptions of independence through time. RESULTS: Older people suggested that objective representations underestimated, and omitted, important aspects of their independence through time. Some participants perceived "snapshot" judgments of their independence as insensitive to their individual values and context. Change over time required some participants to adapt their methods for maintaining independence. The stability of participants' sense of independence was value dependent and informed by the purpose a participant ascribed to maintaining independence. DISCUSSION AND IMPLICATIONS: This study augments the understanding of independence as a complex and multifaceted construct. The findings challenge the congruence of common interpretations of independence with older people's views, showing areas of commonality, and discrepancy. Exploration of independence in terms of form and function provides an important understanding of how function takes precedence to form in determining the maintenance of independence through time.

RESUMEN

BACKGROUND: Delirium affects over 20% of all hospitalised older adults. Delirium is associated with a number of adverse outcomes following hospital admission including cognitive decline, anxiety and depression, increased mortality and care needs. Previous research has addressed prevention of delirium in hospitals and care homes, and there are guidelines on short-term treatment of delirium during admission. However, no studies have addressed the problem of longer-term recovery after delirium and it is currently unknown whether interventions to improve recovery after delirium are effective and cost-effective. The primary objective of this feasibility study is to test a new, theory-informed rehabilitation intervention (RecoverED) in older adults delivered following a hospital admission complicated by delirium to determine whether (a) the intervention is acceptable to individuals with delirium and (b) a definitive trial and parallel economic evaluation of the intervention are feasible. METHODS: The study is a multi-centre, single-arm feasibility study of a rehabilitation intervention with an embedded process evaluation. Sixty participants with delirium (aged > 65 years old) and carer pairs will be recruited from six NHS acute hospitals across the UK. All pairs will be offered the intervention, with follow-up assessments conducted at 3 months and 6 months post-discharge home. The intervention will be delivered in participants' own homes by therapists and rehabilitation support workers for up to 10 intervention sessions over 12 weeks. The intervention will be tailored to individual needs, and the chosen intervention plan and goals will be discussed and agreed with participants and carers. Quantitative data on reach, retention, fidelity and dose will be collected and summarised using descriptive statistics. The feasibility outcomes that will be used to determine whether the study meets the criteria for progression to a definitive randomised controlled trial (RCT) include recruitment, delivery of the intervention, retention, data collection and acceptability of outcome measures. Acceptability of the intervention will be assessed using in-depth, semi-structured qualitative interviews with participants and healthcare professionals. DISCUSSION: Findings will inform the design of a pragmatic multi-centre RCT of the effectiveness and cost-effectiveness of the RecoverED intervention for helping the longer-term recovery of people with delirium compared to usual care. TRIAL REGISTRATION: The feasibility study was registered: ISRCTN15676570.

RESUMEN

PURPOSE: Hip fracture is common in older people - with prevalence even higher for people with dementia. Research often excludes people with dementia - especially those in the more advanced stages. Therefore, the most appropriate interventions remain unknown. The main aim of this study was to gain consensus about the core considerations needed to deliver a physical intervention for people with advanced dementia who fracture their hip. Materials and Methods: An expert consensus process was undertaken, using Nominal Group Technique, to explore the key considerations when delivering rehabilitation. Data collection was undertaken in January 2023 and involved an online group discussion followed by voting and off-line rating. Qualitative content analysis and quantitative analysis of consensus scoring was undertaken. An international group of seven highly specialised physiotherapists took part. RESULTS: 59 statements were agreed following the process. Content analysis was used to categorise these statements according to the International Classification of Functioning, Disability and Health. Although consensus levels were high, there was disagreement in several areas. CONCLUSION: The statements provide an overarching understanding of the multidisciplinary expertise that is needed to effectively deliver rehabilitation interventions to this population. People with dementia require highly skilled and trained professionals, providing holistic and person-centred approaches to deliver rehabilitation interventions.IMPLICATIONS FOR REHABILITATIONThe expert consensus provides an overarching understanding of the multidisciplinary expertise that is needed to effectively deliver rehabilitation interventions to this population.Physiotherapy - or other interventions - cannot be used in isolation.People with dementia require highly skilled and trained professionals, providing holistic and person-centred approaches to deliver rehabilitation interventions.While our focus was on hip fracture, we suggest these statements can be used for people with advanced dementia with a variety of other conditions.

RESUMEN

To date there has been little focus on the concept of joy amongst older people in the literature. The objective of this scoping review was to understand the extent and type of evidence about joy and older people. Searches were run in ten databases in January 2022 (re-run January 2023). Eligible studies included people aged 65 and over living in their usual place of residence and described the experience or evaluation of joy. Screening was conducted independently by two reviewers and data were extracted by one reviewer and checked by a second. We included 11 papers reporting both qualitative (n = 5) and quantitative (n = 6) studies involving 1,487 participants with a mean age of 81.6 years. Seven of the studies were based in care or nursing homes with four in community settings. Five studies reported the experience of joy, three reported on the assessment of joy, and three examined the association between joy and other factors. Social connections and participation in activities that are meaningful to the individual are important sources of joy. Joy amongst older people has received little attention in the literature despite it being highlighted as being important to older people themselves in relation to their health and wellbeing.

RESUMEN

OBJECTIVES: The aim of this study was to explore healthcare professionals' principles for providing and delivering rehabilitation interventions for people with advanced dementia. DESIGN: This was a qualitative study with three focus groups undertaken virtually. The data were analysed using a process of reflexive thematic analysis in order to gain an in-depth understanding of rehabilitation principles for this population. SETTING AND PARTICIPANTS: 20 healthcare professionals who were specialists in treating and rehabilitating people with advanced dementia were recruited. These healthcare professionals had a wide range of experience in a variety of different settings including primary care, secondary care as well as specialist mental health teams. Purposive sampling focused on the requirement for participants to have significant experience of treating people with dementia. Participants were from the UK and Denmark. Data collection was undertaken during August and September 2022. RESULTS: Three overarching themes were developed following analysis-organisational culture, knowledge and personal values of the healthcare professional. The first explored how the culture of an organisation affects a person with advanced dementia as well as the healthcare professional. The organisation needed to promote positive approaches to person-centred care and provide effective situational leadership to embed such approaches. Knowledge was a key consideration and was closely linked to the personal values of the healthcare professional, which formed the final theme. This study suggests that the interrelationship of these three factors influences the outcomes for the person with dementia and effective outcomes required consideration of all domains. CONCLUSIONS: Effective interventions for people with advanced dementia require the healthcare professional to have the knowledge about dementia and positive personal values, but the culture of the organisation is also key to ensure that the healthcare professional is able to deliver successful interventions.

RESUMEN

BACKGROUND: Older people are often explicitly or implicitly excluded from research, in particular clinical trials. This means that study findings may not be applicable to them, or that older people may not be offered treatments due to an absence of evidence. AIMS: The aim of this work was to develop recommendations to guide all research relevant to older people. METHODS: A diverse stakeholder group identified barriers and solutions to including older people in research. In parallel, a rapid literature review of published papers was undertaken to identify existing papers on the inclusion of older people in research. The findings were synthesised and mapped onto a socio-ecological model. From the synthesis we identified themes that were developed into initial recommendations that were iteratively refined with the stakeholder group. RESULTS: A range of individual, interpersonal, organisational, community and policy factors impact on the inclusion of older people in research. A total of 14 recommendations were developed such as removing upper age limits and comorbidity exclusions, involving older people, advocates and health and social care professionals with expertise in ageing in designing the research, and considering flexible or alternative approaches to data collection to maximise opportunities for participation. We also developed four questions that may guide those developing, reviewing and funding research that is inclusive of older people. CONCLUSION: Our recommendations provide up to date, practical advice on ways to improve the inclusion of older people in health and care research.

RESUMEN

Background: Gait disturbances often result in functional limitations in daily activities and negatively impact the quality of life in people with Parkinson's disease. Physiotherapists often employ compensation strategies in an attempt to improve patients' walking. However, little is known about physiotherapists' experiences in this regard. We evaluated how physiotherapists adopt compensation strategies and what they draw on to inform their clinical decision-making. Methods: We carried out semi-structured online interviews with 13 physiotherapists with current or recent experience working with people with Parkinson's disease in the United Kingdom. Interviews were digitally recorded and transcribed verbatim. Thematic analysis was utilized. Results: Two main themes were developed from the data. The first theme, optimizing compensation strategies through personalized care, shows how physiotherapists accounted for the individual needs and characteristics of people with Parkinson's, which resulted in them individually tailoring compensation strategies. The second theme, delivering compensation strategies effectively, considers the available support and perceived challenges with work settings and experience that impact physiotherapists' ability to deliver compensation strategies. Discussion: Although physiotherapists strived to optimize compensation strategies, there was a lack of formal training in this area, and their knowledge was primarily acquired from peers. Furthermore, a lack of specific knowledge on Parkinson's can impact physiotherapists' confidence in maintaining person-centered rehabilitation. However, the question that remains to be answered is what accessible training could address the knowledge-practice gap to contribute to the delivery of better-personalized care for people with Parkinson's.

RESUMEN

BACKGROUND: The Risk Assessment for moving Individuals SafEly (RAISE) program is a hospital-based manual handling nursing training program. RAISE involves upskilling on continual risk assessment during patient-assisted movements. RAISE aims to optimise staff and patient safety while providing the patient with movement and rehabilitation opportunities. Implementation of RAISE in the hospital setting has been established. The aim of this study was to explore the feasibility of implementing RAISE in the long-term care setting. METHODS: We examined three feasibility domains: acceptability, practicality, and limited efficacy (observed nursing behaviour change which has the potential to reduce nursing injuries), using a prospective pilot pre-post design in the long-term care setting. Staff completed a 4-hour training session on RAISE delivered by two physiotherapists, followed by 8 h of supported behaviour change in the workplace. Staff acceptability and practicality of incorporating risk assessment strategies into manual handling approaches were explored through pre- and post-training staff surveys and a semi-structured interview. Resident acceptability of manual handling practices was explored via survey data collected after the RAISE training. Pre to post-training changes in staff knowledge and behaviour were examined through the pre- and post-training staff survey, and observation of staff assisting resident movement. RESULTS: Two enrolled nurses and five residents participated. Staff reported the RAISE program was acceptable and practical to implement in the long-term care setting. There were no adverse events or safety concerns. Staff reported the RAISE program provided guidance and enhanced staff empowerment to make decisions during assisted resident movement. There were 26 observed resident-staff manual handling interactions recorded, with 13 pre-training and 13 post-training. Post-training, RAISE skills had improved and were completed 100% of the time, except for completing a physical risk assessment which improved from 46 to 85%, demonstrating limited efficacy. Residents reported it's important for staff to be trained on how to assist them to mobilise and they found the concept of the RAISE program acceptable. CONCLUSIONS: This pilot study supports the feasibility of long-term care facilities participating in future studies testing the effectiveness and cost-effectiveness of the Risk Assessment for moving Individuals SafEly (RAISE) patient and resident manual handling program.

RESUMEN

Dementia is a growing global challenge with numbers set to increase rapidly in the coming years. Evidence suggests that exercise can be effective in improving cognitive functioning, but the evidence does not yet support improvements in other key domains such as quality of life or physical ability. The aim of this study was to explore the key components that needed to be considered when providing physical rehabilitation to people with advanced dementia. The study used a qualitative approach involving semi-structured focus groups with health care professionals who are experts in delivering interventions to people with advanced dementia. As a pragmatic study seeking to inform the development of interventions, a thematic coding approach was used to make sense of the data. We collected data from 20 healthcare professionals who reported that key considerations needed to be considered from both an assessment and an intervention perspective. The assessment needed to be person centred and, with the right people engaged and using outcome measures that were meaningful to the patient. The actual intervention also needed to follow the principles of person-centred care, with emphasis placed on the importance of taking time to build a rapport with the person, but also reducing any of the barriers that would prevent effective engagement, such as unsuitable environments. Our study suggests that while there are barriers and challenges to providing interventions and rehabilitation to people with advanced dementia, appropriate person-centred, tailored interventions can be effective and therefore should be offered.

RESUMEN

AIM: The aim of the study was to reach consensus on modifiable risk factors for a novel system of care to address Manifestations of Frailty in hospitalized older adults. DESIGN: Consensus study. METHOD: A modified nominal group technique, incorporating expert group face-to-face interaction, review of existing evidence and pre/post-meeting questionnaire completion was undertaken November 2019-February 2020. RESULTS: Seventy-one risk factors, within seven risk factor domains (pain, medication, fluid and nutrition intake, mobility, elimination, infection, additional patient factors) were considered. It was agreed that 44 risk factors incorporating patient, organizational and environmental risk factors were modifiable and should be included in a novel system of care.

RESUMEN

The ability of gut microbial metabolites to influence the host is increasingly recognized. The microbiota extensively metabolizes the three aromatic amino acids, tryptophan, tyrosine, and phenylalanine. Previously we have found that a metabolite of tyrosine, 4-OH-phenylpropionic acid, can enhance type I interferon (IFN) signaling and protect from influenza pathogenesis in a murine model. Herein we screened 17 related aromatic amino acid metabolites for effects on IFN signaling in human lung epithelial cells and monocytes alone and in the presence of IFN-ß, influenza, and LPS. While the tryptophan family metabolites reduced IFN signaling in both cell types, the tyrosine and phenylalanine metabolites had varied effects, which were cell-type dependent. Pooled treatment of all these metabolites reduced IFN signaling in both cell types and suggested a tryptophan metabolite effect dominance. Strikingly, when all the metabolites were pooled together, we found reduced influenza recovery in both cell types. RNA sequencing further validated reduced viral loads and decreased IFN signaling. Single gene silencing of significantly upregulated genes identified by RNA sequencing (EGR2, ATP6VD02, SPOCK1, and IL31RA) did not completely abrogate the metabolite induced decrease in IFN signaling. However, these upregulated targets suggested a mechanistic link to TGF-beta signaling. Treatment with a TGF-beta inhibitor and combined targeted gene silencing led to a significant reversal of metabolite induced IFN signaling suppression. Finally, we demonstrated that intranasal administration of these metabolites prior to influenza infection led to reduced animal morbidity, viral titers, and inflammation. Our work implies that microbial metabolites can alter IFN signaling mechanistically through TGF-beta and promote beneficial outcomes during influenza infection.

RESUMEN

PURPOSE: People with Parkinson's are twice as likely to fall as older people within the general population. This longitudinal qualitative study was part of a larger programme of research including a randomised controlled trial to test the effectiveness of a tailored physiotherapy intervention. Specific qualitative aims focused on a subsample of trial participants in the intervention arm of the trial, and comprised the following:To explore the expectations of participants about the intervention.To investigate participants' experiences of the intervention, and its perceived impacts.To understand the facilitators and barriers to engagement. METHODS: Two semi-structured interviews were completed with a theoretical sample of people with Parkinson's from the intervention arm, initially after randomisation but before the intervention commenced, and then again six months later. RESULTS: Forty-two participants out of a large clinical trial were interviewed initially, with 37 agreeing to a second interview at six months. Prior experience of rehabilitation plus information accessed through the trial consent procedure informed participants' realistic expectations. Most found the level of the intervention acceptable, and perceived a range of benefits. However, views about equipment provided were more equivocal. The biggest barriers to participation were time and motivation, whilst social support facilitated engagement with the intervention. CONCLUSIONS: This study is the first to capture expectations about participation in a programme of exercises and strategies. It highlights that previous challenges to engagement in physical exercises and activities are not a barrier to future participation and provides new insights into the role of equipment and technology in programmes of physical activity for people with Parkinson's. The challenge of ensuring that programmes of exercise and strategies become an embedded feature of everyday life is highlighted, particularly alongside busy social engagements and leisure pursuits.Implications for rehabilitationFor people with Parkinsons, a programme of exercises and strategies has the potential to reduce the risk of falls amongst those with a history of falling.Adherence to such programmes can prove challenging for a variety of reasons, even when participants have realistic expectations about the commitment and effort needed.Clear explanations about the role of equipment and technology within such programmes could enhance adherence.In order to further individualise programmes of exercise for people with Parkinsons, choice regarding social support, reminders and integration into everyday activities should be explored.

RESUMEN

BACKGROUND: Low physical activity levels are a major problem for people in hospital and are associated with adverse outcomes. OBJECTIVE: This systematic review, meta-analysis and meta-regression aimed to determine the effect of behaviour change interventions on physical activity levels in hospitalised patients. METHODS: Randomised controlled trials of behaviour change interventions to increase physical activity in hospitalised patients were selected from a database search, supplemented by reference list checking and citation tracking. Data were synthesised with random-effects meta-analyses and meta-regression analyses, applying Grades of Recommendation, Assessment, Development and Evaluation criteria. The primary outcome was objectively measured physical activity. Secondary measures were patient-related outcomes (e.g. mobility), service level outcomes (e.g. length of stay), adverse events and patient satisfaction. RESULTS: Twenty randomised controlled trials of behaviour change interventions involving 2,568 participants (weighted mean age 67 years) included six trials with a high risk of bias. There was moderate-certainty evidence that behaviour change interventions increased physical activity levels (SMD 0.34, 95% CI 0.14-0.55). Findings in relation to mobility and length of stay were inconclusive. Adverse events were poorly reported. Meta-regression found behaviour change techniques of goal setting (SMD 0.29, 95% CI 0.05-0.53) and feedback (excluding high risk of bias trials) (SMD 0.35, 95% CI 0.11-0.60) were independently associated with increased physical activity. CONCLUSIONS: Targeted behaviour change interventions were associated with increases in physical activity in hospitalised patients. The trials in this review were inconclusive in relation to the patient-related or health service benefits of increasing physical activity in hospital.
