Investigating Patient Use and Experience of Online Appointment Booking in Primary Care: Mixed Methods Study.

BACKGROUND: Online appointment booking is a commonly used tool in several industries. There is limited evidence about the benefits and challenges of using online appointment booking in health care settings. Potential benefits include convenience and the ability to track appointments, although some groups of patients may find it harder to engage with online appointment booking. We sought to understand how patients in England used and experienced online appointment booking. OBJECTIVE: This study aims to describe and compare the characteristics of patients in relation to their use of online appointment booking in general practice and investigate patients' views regarding online appointment booking arrangements. METHODS: This was a mixed methods study set in English general practice comprising a retrospective analysis of the General Practice Patient Survey (GPPS) and semistructured interviews with patients. Data used in the retrospective analysis comprised responses to the 2018 and 2019 GPPS analyzed using mixed-effects logistic regression. Semistructured interviews with purposively sampled patients from 11 general practices in England explored experiences of and views on online appointment booking. Framework analysis was used to allow for comparison with the findings of the retrospective analysis. RESULTS: The retrospective analysis included 1,327,693 GPPS responders (2018-2019 combined). We conducted 43 interviews with patients with a variety of experiences and awareness of online appointment booking; of these 43 patients, 6 (14%) were from ethnic minority groups. In the retrospective analysis, more patients were aware that online appointment booking was available (581,224/1,288,341, 45.11%) than had experience using it (203,184/1,301,694, 15.61%). There were deprivation gradients for awareness and use and a substantial decline in both awareness and use in patients aged >75 years. For interview participants, age and life stage were factors influencing experiences and perceptions, working patients valued convenience, and older patients preferred to use the telephone. Patients with long-term conditions were more aware of (odds ratio [OR] 1.43, 95% CI 1.41-1.44) and more likely to use (OR 1.65, 95% CI 1.63-1.67) online appointment booking. Interview participants with long-term conditions described online appointment booking as useful for routine nonurgent appointments. Patients in deprived areas were clustered in practices with low awareness and use of online appointment booking among GPPS respondents (OR for use 0.65, 95% CI 0.64-0.67). Other key findings included the influence of the availability of appointments online and differences in the registration process for accessing online booking. CONCLUSIONS: Whether and how patients engage with online appointment booking is influenced by the practice with which they are registered, whether they live with long-term conditions, and their deprivation status. These factors should be considered in designing and implementing online appointment booking and have implications for patient engagement with the wider range of online services offered in general practice.

Addressing the psychology of weight loss and maintenance: A feasibility study of the Skills for weight loss and Maintenance weight management programme.

OBJECTIVES: Building on prior theory, we aimed to evaluate the feasibility and acceptability of integrating novel, weight loss maintenance strategies into existing weight management programmes. We also piloted recruitment and data collection procedures for future research. DESIGN: Two phases of action research nested within a single-arm feasibility study. The intervention was refined between phases using feedback from intervention fidelity analysis and qualitative exploration of patient and provider experiences. Changes in outcomes were assessed up to 18 months post-baseline. METHODS: One hundred adults with a mean body mass index of 37 kg/m2 were offered the Skills for weight loss and Maintenance (SkiM) intervention. This included existing weight management programme content and additional weight loss maintenance techniques delivered fortnightly for 6 months in local community centres to groups of 11-15 people. RESULTS: Of the 100 participants, 65%, 58% and 56% provided data at 7, 12 and 18 months. Across both phases, the mean initial weight loss was 4.2 kg (95% CI: 2.4-5.9) and 3.1 kg at 18 months (95% CI: .8-5.5). In Phase 2, we observed better weight loss maintenance (.5 kg [13.2%] regain from 7 to 18 months, vs. 1.7 kg [36.2%] in Phase 1). Variation in outcomes, high early dropout rates and qualitative feedback indicated that, although delivery of the intervention and trial procedures was feasible and acceptable, there was scope to refine the intervention to engage a wider range of participants. Intervention fidelity was acceptable, particularly in Phase 2. CONCLUSIONS: The SkiM intervention seems promising, but more research is needed to improve recruitment and retention prior to further evaluation.

Shared decision making between older people with multimorbidity and GPs: a qualitative study.

BACKGROUND: Shared decision making (SDM), utilising the expertise of both patient and clinician, is a key feature of good-quality patient care. Multimorbidity can complicate SDM, yet few studies have explored this dynamic for older patients with multimorbidity in general practice. AIM: To explore factors influencing SDM from the perspectives of older patients with multimorbidity and GPs, to inform improvements in personalised care. DESIGN AND SETTING: Qualitative study. General practices (rural and urban) in Devon, England. METHOD: Four focus groups: two with patients (aged ≥65 years with multimorbidity) and two with GPs. Data were coded inductively by applying thematic analysis. RESULTS: Patient acknowledgement of clinician medicolegal vulnerability in the context of multimorbidity, and their recognition of this as a barrier to SDM, is a new finding. Medicolegal vulnerability was a unifying theme for other reported barriers to SDM. These included expectations for GPs to follow clinical guidelines, challenges encountered in applying guidelines and in communicating clinical uncertainty, and limited clinician self-efficacy for SDM. Increasing consultation duration and improving continuity were viewed as facilitators. CONCLUSION: Clinician perceptions of medicolegal vulnerability are recognised by both patients and GPs as a barrier to SDM and should be addressed to optimise delivery of personalised care. Greater awareness of multimorbidity guidelines is needed. Educating clinicians in the communication of uncertainty should be a core component of SDM training. The incorrect perception that most clinicians already effectively facilitate SDM should be addressed to improve the uptake of personalised care interventions.

Comparing international postgraduate training and healthcare context with the UK to streamline overseas GP recruitment: four case studies.

BACKGROUND: There are ambitious overseas recruitment targets to alleviate current GP shortages in the UK. GP training in European Economic Area (EEA) countries is recognised by the General Medical Council (GMC) as equivalent UK training; non-EEA GPs must obtain a Certificate of Eligibility for General Practice Registration (CEGPR), demonstrating equivalence to UK-trained GPs. The CEGPR may be a barrier to recruiting GPs from non-EEA countries. It is important to facilitate the most streamlined route into UK general practice while maintaining registration standards and patient safety. AIM: To apply a previously published mapping methodology to four non-EEA countries: South Africa, US, Canada, and New Zealand. DESIGN & SETTING: Desk-based research was undertaken. This was supplemented with stakeholder interviews. METHOD: The method consisted of: (1) a rapid review of 13 non-EEA countries using a structured mapping framework, and publicly available website content and country-based informant interviews; (2) mapping of five 'domains' of comparison between four overseas countries and the UK (healthcare context, training pathway, curriculum, assessment, and continuing professional development (CPD) and revalidation). Mapping of the domains involved desk-based research. A red, amber, or green (RAG) rating was applied to indicate the degree of alignment with the UK. RESULTS: All four countries were rated 'green'. Areas of differences that should be considered by regulatory authorities when designing streamlined CEGPR processes for these countries include: healthcare context (South Africa and US), CPD and revalidation (US, Canada, and South Africa), and assessments (New Zealand). CONCLUSION: Mapping these four non-EEA countries to the UK provides evidence of utility of the systematic method for comparing GP training between countries, and may support the UK's ambitions to recruit more GPs to alleviate UK GP workforce pressures.

Awareness and use of online appointment booking in general practice: analysis of GP Patient Survey data.

BACKGROUND: General practices are required to provide online booking to patients in line with policy to digitise access. However, uptake of online booking by patients is currently low and there is little evidence about awareness and use by different patient groups. AIM: To examine variability in awareness and use of online appointment booking in general practice. METHOD: Secondary analysis of two questions from the GP Practice Survey data (2018) asking about awareness and use of online booking of appointments. Multivariable logistic regression was used to examine associations with age, gender, ethnicity, deprivation, the presence of a long-term condition, long-term sickness and being deaf. RESULTS: In total, 43.3% (277 278/647 064) of responders reported being aware of being able to book appointments online, while only 15% (93 671/641 073) reported doing so. There was evidence of variation by all factors considered, with strong deprivation gradients in both awareness and use (for example, most versus least deprived quintile OR for use: 0.63 (95% CI = 0.61 to 0.65). There was a reduction in awareness and use in patients >75 years of age. Patients with long-term conditions were more aware and more likely to use online booking. CONCLUSION: While over 40% of patients know that they can book appointment online, the number that actually do so is far lower. With the constant push for online services within the NHS and the roll out of the NHS app, practices should be aware that not all patient groups will book appointments online and that other routes of access need to be maintained to avoid widening health inequalities.

The dynamics of decision-making in weight loss and maintenance: a qualitative enquiry.

BACKGROUND: Behavioural approaches to weight loss are often initially successful but less so in the longer term, as some people maintain the necessary behaviour changes while others do not. This study aimed to derive possible explanations for this using a qualitative approach with a view to improving intervention effectiveness. METHODS: Thirty-six participants in a development and feasibility study for a weight loss and maintenance intervention (called SkiM) were interviewed three times over 18 months regarding their experiences before, during and after the intervention. Data were analysed thematically. The accounts of those who were more and less successful in terms of longer term weight loss were compared, and a conceptual model linking the main analytic themes was developed. RESULTS: Five interpretative themes were generated: encountering and managing key situations; the impact of emotion; the source of control; personal values; and acquiring knowledge and skills. These themes were linked through a model of decision-making during key situations. In this model, behavioural decisions emerge from a dynamic interplay between several drivers: emotional state and needs, perceived control, personal values, the individual's knowledge and skills, and their existing habits. The individual's response in key situations generates experiential learning that can influence decisional dynamics in similar situations in future. These dynamics appeared to differ between participants, and between those who were more and less successful in weight management. CONCLUSIONS: Our analysis and model of decision-making during weight-management have implications for the development and delivery of behavioural weight management interventions. By helping individuals to identify the drivers of their decision-making in key situations, and equipping them to manage these drivers, programmes may enhance their capacity to sustain the behaviour changes needed for long-term weight loss.

Hope and despair: a qualitative exploration of the experiences and impact of trial processes in a rehabilitation trial.

BACKGROUND: Unanticipated responses by research participants can influence randomised controlled trials (RCTs) in multiple ways, many of which are poorly understood. This study used qualitative interviews as part of an embedded process evaluation to explore the impact participants may have on the study, but also unintended impacts the study may have on them. AIM: The aim of the study was to explore participants' experiences and the impact of trial involvement in a pilot RCT in order to inform the designing and delivery of a definitive RCT. METHODS: In-depth interviews with 20 participants (10 in the intervention and 10 in the control group) enrolled in a stroke rehabilitation pilot trial. A modified framework approach was used to analyse transcripts. RESULTS: Participation in the study was motivated partly by a desperation to receive further rehabilitation after discharge. Responses to allocation to the control group included an increased commitment to self-treatment, and negative psychological consequences were also described. Accounts of participants in both control and intervention groups challenge the presumption that they were neutral, or in equipoise, regarding group allocation prior to consenting to randomisation. CONCLUSIONS: Considering and exploring participant and participation effects, particularly in the control group, highlights numerous issues in the interpretation of trial studies, as well as the in ethics of RCTs more generally. While suggestions for a definitive trial design are given, further research is required to investigate the significant implications these findings may have for trial design, monitoring and funding.

Acceptability and experience of a functional training programme (ReTrain) in community-dwelling stroke survivors in South West England: a qualitative study.

Rehabilitation Training (ReTrain) is a group-based approach to functional training post stroke. ReTrain has recently been evaluated through a pilot randomised controlled trial. OBJECTIVE: This article reports on the acceptability of the intervention as described by trial participants. DESIGN: A qualitative approach was undertaken. Of the 45 participants recruited into the trial, 23 were randomised to receive ReTrain. Following a sampling strategy, 10 participants undertook 1:1 semistructured audio-recorded interviews. Transcripts were analysed following a modified Framework Approach. RESULTS: Six themes were developed including exploration of: the physical and psychological impacts of training,the perceived mechanisms of change, the interaction of the group and approach of the trainer. A further theme considered the reported longer term impact of participation. Overall, the results indicated the acceptability of the intervention, but also key areas for potential modification in the definitive trial. These include a need to consider potential impact on both physical and psychological function, careful consideration of dosing and fatigue and the interpersonal factors that facilitate appropriate level of delivery, the trainer to participant ratio, and enhancing features that support continuation of activity postintervention. CONCLUSION: Overall, this study supports the acceptability of ReTrain and the development of a definitive trial evaluation of this intervention to full. TRIAL REGISTRATION NUMBER: NCT02429180.

Physical activity, sleep, and fatigue in community dwelling Stroke Survivors.

Stroke can lead to physiological and psychological impairments and impact individuals' physical activity (PA), fatigue and sleep patterns. We analysed wrist-worn accelerometry data and the Fatigue Assessment Scale from 41 stroke survivors following a physical rehabilitation programme, to examine relationships between PA levels, fatigue and sleep. Validated acceleration thresholds were used to quantify time spent in each PA intensity/sleep category. Stroke survivors performed less moderate to vigorous PA (MVPA) in 10 minute bouts than the National Stroke guidelines recommend. Regression analysis revealed associations at baseline between light PA and fatigue (p = 0.02) and MVPA and sleep efficiency (p = 0.04). Light PA was positively associated with fatigue at 6 months (p = 0.03), whilst sleep efficiency and fatigue were associated at 9 months (p = 0.02). No other effects were shown at baseline, 6 or 9 months. The magnitude of these associations were small and are unlikely to be clinically meaningful. Larger trials need to examine the efficacy and utility of accelerometry to assess PA and sleep in stroke survivors.

Community-based rehabilitation training after stroke: results of a pilot randomised controlled trial (ReTrain) investigating acceptability and feasibility.

OBJECTIVES: To assess acceptability and feasibility of trial processes and the Rehabilitation Training (ReTrain) intervention including an assessment of intervention fidelity. DESIGN: A two-group, assessor-blinded, randomised controlled trial with parallel mixed methods process and economic evaluations. SETTING: Community settings across two sites in Devon. PARTICIPANTS: Eligible participants were: 18 years old or over, with a diagnosis of stroke and with self-reported mobility issues, no contraindications to physical activity, discharged from National Health Service or any other formal rehabilitation programme at least 1 month before, willing to be randomised to either control or ReTrain and attend the training venue, possessing cognitive capacity and communication ability sufficient to participate. Participants were individually randomised (1:1) via a computer-generated randomisation sequence minimised for time since stroke and level of functional disability. Only outcome assessors independent of the research team were blinded to group allocation. INTERVENTIONS: ReTrain comprised (1) an introductory one-to-one session; (2) ten, twice-weekly group classes with up to two trainers and eight clients; (3) a closing one-to-one session, followed by three drop-in sessions over the subsequent 3 months. Participants received a bespoke home-based training programme. All participants received treatment as usual. The control group received an exercise after stroke advice booklet. OUTCOME MEASURES: Candidate primary outcomes included functional mobility and physical activity. RESULTS: Forty-five participants were randomised (ReTrain=23; Control=22); data were available from 40 participants at 6 months of follow-up (ReTrain=21; Control=19) and 41 at 9 months of follow-up (ReTrain=21; Control=20). We demonstrated ability to recruit and retain participants. Participants were not burdened by the requirements of the study. We were able to calculate sample estimates for candidate primary outcomes and test procedures for process and health economic evaluations. CONCLUSIONS: All objectives were fulfilled and indicated that a definitive trial of ReTrain is feasible and acceptable. TRIAL REGISTRATION NUMBER: NCT02429180; Results.

Understanding the challenge of weight loss maintenance: a systematic review and synthesis of qualitative research on weight loss maintenance.

Behaviour change interventions can be effective in helping people to lose weight, but weight is often regained. Effective interventions are required to prevent this. We conducted a systematic review and synthesis of qualitative research on people's experiences of weight loss maintenance. We searched bibliographic databases for qualitative studies about the experience of currently or previously overweight adults trying to maintain weight loss. We thematically synthesised study findings to develop a model of weight loss maintenance. Twenty six studies from five countries with 710 participants were included. The model developed through our synthesis proposes that making the behaviour changes required for weight loss maintenance generates psychological 'tension' due to the need to override existing habits, and incompatibility of the new behaviours with the fulfilment of psychological needs. Successful maintenance involves management or resolution of this tension. Management of tension can be achieved through self-regulation, renewing of motivation and managing external influences, although this can require constant effort. Resolution may be achieved through changing habits, finding non-obesogenic methods for addressing needs, and potentially through change in self-concept. Implications for the development of weight loss maintenance interventions are explored.

Community-based Rehabilitation Training after stroke: protocol of a pilot randomised controlled trial (ReTrain).

INTRODUCTION: The Rehabilitation Training (ReTrain) intervention aims to improve functional mobility, adherence to poststroke exercise guidelines and quality of life for people after stroke. A definitive randomised controlled trial (RCT) is required to assess the clinical and cost-effectiveness of ReTrain, which is based on Action for Rehabilitation from Neurological Injury (ARNI). The purpose of this pilot study is to assess the feasibility of such a definitive trial and inform its design. METHODS AND ANALYSIS: A 2-group, assessor-blinded, randomised controlled external pilot trial with parallel mixed-methods process evaluation and economic evaluation. 48 participants discharged from clinical rehabilitation despite residual physical disability will be individually randomised 1:1 to ReTrain (25 sessions) or control (exercise advice booklet). Outcome assessment at baseline, 6 and 9 months include Rivermead Mobility Index; Timed Up and Go Test; modified Patient-Specific Functional Scale; 7-day accelerometry; Stroke Self-efficacy Questionnaire, exercise diary, Fatigue Assessment Scale, exercise beliefs and self-efficacy questionnaires, SF-12, EQ-5D-5L, Stroke Quality of Life, Carer Burden Index and Service Receipt Inventory. Feasibility, acceptability and process outcomes include recruitment and retention rates; with measurement burden and trial experiences being explored in qualitative interviews (20 participants, 3 intervention providers). Analyses include descriptive statistics, with 95% CI where appropriate; qualitative themes; intervention fidelity from videos and session checklists; rehearsal of health economic analysis. ETHICS AND DISSEMINATION: National Health Service (NHS) National Research Ethics Service approval granted in April 2015; recruitment started in June. Preliminary studies suggested low risk of serious adverse events; however (minor) falls, transitory muscle soreness and high levels of postexercise fatigue are expected. Outputs include pilot data to inform whether to proceed to a definitive RCT and support a funding application; finalised Trainer and Intervention Delivery manuals for multicentre replication of ReTrain; presentations at conferences, public involvement events; internationally recognised peer-reviewed journal publications, open access sources and media releases. TRIAL REGISTRATION NUMBER: NCT02429180; Pre-results.

Assessing the impact of upper limb disability following stroke: a qualitative enquiry using internet-based personal accounts of stroke survivors.

PURPOSE: Upper limb disability following stroke may have multiple effects on the individual. Existing assessment instruments tend to focus on impairment and function and may miss other changes that are personally important. This study aimed to identify personally significant impacts of upper limb disability following stroke. METHODS: Accounts by stroke survivors, in the form of web-based diaries (blogs) and stories, were sought using a blog search engine and in stroke-related web-sites. Thematic analysis using the World Health Organisation's International Classification of Functioning Disability and Health (ICF) was used to identify personal impacts of upper limb disability following stroke. RESULTS: Ninety-nine sources from at least four countries were analysed. Many impacts were classifiable using the ICF, but a number of additional themes emerged, including emotional, cognitive and behavioural changes. Blogs and other web-based accounts were easily accessible and rich sources of data, although using them raised several methodological issues, including potential sample bias. CONCLUSIONS: A range of impacts was identified, some of which (such as use of information technology and alienation from the upper limb) are not addressed in current assessment instruments. They should be considered in post-stroke assessments. Blogs may help in the development of more comprehensive assessments. IMPLICATIONS FOR REHABILITATION: A comprehensive assessment of the upper limb following stroke should include the impact of upper limb problems on social participation, as well as associated emotional, cognitive and behavioural changes. Using personalised assessment instruments alongside standardised measures may help ensure that these broader domains are considered in discussions between clinicians and patients. Rehabilitation researchers should investigate whether and how these domains could be addressed and operationalised in standard upper limb assessment instruments.

Motivators for uptake and maintenance of exercise: perceptions of long-term stroke survivors and implications for design of exercise programmes.

PURPOSE: Exercise-after-stroke programmes are increasingly being provided to encourage more physical exercise among stroke survivors, but little is known about what motivates people with stroke to participate in them. This research aimed to identify factors that motivate long-term stroke survivors to exercise, and the implications for programme design. METHODS: In two separate studies, focus groups and individual interviews were used to investigate the views of long-term stroke survivors on exercise and participating in exercise programmes. Their data were analysed thematically, and the findings of the studies were synthesised. RESULTS: Eleven stroke survivors and two partners took part in two focus groups; six other stroke survivors (one with a partner) were interviewed individually. Factors reported to influence motivation were the psychological benefits of exercise, a desire to move away from a medicalised approach to exercise, beliefs about stroke recovery, and on-going support to sustain commitment. A number of potential implications of these themes for exercise programme design were identified. CONCLUSIONS: A range of personal beliefs and attitudes and external factors may affect the motivation to exercise, and these vary between individuals. Addressing these factors in the design of exercise programmes for long-term stroke survivors may enhance their appeal and so encourage greater engagement in exercise. IMPLICATIONS FOR REHABILITATION: Exercise programmes may be more attractive to long-term stroke survivors if the psychological well-being benefits of participation are emphasised in their promotion. Some participants will be more attracted by programmes that are de-medicalised, for example, by being located away from clinical settings, and led by or involving suitably-trained non-clinicians. Programmes offered in different formats may attract stroke survivors with different beliefs about the value of exercise in stroke recovery. Programmes should provide explicit support strategies for on-going engagement in exercise.

Intervention fidelity: developing an experience-based model for rehabilitation research.

BACKGROUND: Intervention fidelity is concerned with the extent to which interventions are implemented as intended. Consideration of fidelity is essential if the conclusions of effectiveness studies are to be credible, but little attention has been given to it in the rehabilitation literature. We describe our experiences addressing fidelity in the development of a rehabilitation clinical trial, and consider how an existing model of fidelity may be employed in rehabilitation research. METHODS: We used a model and methods drawn from the psychology literature to investigate how fidelity might be maximised during the planning and development of a stroke rehabilitation trial. We considered fidelity in intervention design, provider training, and the behaviour of providers and participants. We also evaluated methods of assessing fidelity during a trial. RESULTS: We identified strategies to help address fidelity in our trial protocol, along with their potential strengths and limitations. We incorporated these strategies into a model of fidelity that is appropriate to the concepts and language of rehabilitation. CONCLUSION: A range of strategies are appropriate to help maximise and measure fidelity in rehabilitation research. Based on our experiences, we propose a model of fidelity and provide recommendations to inform the growing literature of fidelity in this discipline.

Synthesising practice guidelines for the development of community-based exercise programmes after stroke.

BACKGROUND: Multiple guidelines are often available to inform practice in complex interventions. Guidance implementation may be facilitated if it is tailored to particular clinical issues and contexts. It should also aim to specify all elements of interventions that may mediate and modify effectiveness, including both their content and delivery. We conducted a focused synthesis of recommendations from stroke practice guidelines to produce a structured and comprehensive account to facilitate the development of community-based exercise programmes after stroke. METHODS: Published stroke clinical practice guidelines were searched for recommendations relevant to the content and delivery of community-based exercise interventions after stroke. These were synthesised using a framework based on target intervention outcomes, personal and programme proximal objectives, and recommended strategies. RESULTS: Nineteen guidelines were included in the synthesis (STRIDES; STroke Rehabilitation Intervention-Development Evidence Synthesis). Eight target outcomes, 14 proximal objectives, and 94 recommended strategies were identified. The synthesis was structured to present best practice recommendations in a format that could be used by intervention programme developers. It addresses both programme content and context, including personal factors, service standards and delivery issues. Some recommendations relating to content, and many relating to delivery and other contextual issues, were based on low level evidence or expert opinion. Where opinion varied, the synthesis indicates the range of best practice options suggested in guidelines. CONCLUSIONS: The synthesis may assist implementation of best practice by providing a structured intervention description that focuses on a particular clinical application, addresses practical issues involved in programme development and provision, and illustrates the range of best-practice options available to users where robust evidence is lacking. The synthesis approach could be applied to other areas of stroke rehabilitation or to other complex interventions.

Informing the design of a randomised controlled trial of an exercise-based programme for long term stroke survivors: lessons from a before-and-after case series study.

BACKGROUND: To inform the design of a randomised controlled trial (RCT) of an exercise-based programme for long term stroke survivors, we conducted a mixed methods before-and-after case series with assessment at three time points. We evaluated Action for Rehabilitation from Neurological Injury (ARNI), a personalised, functionally-focussed programme. It was delivered through 24 hours of one-to-one training by an Exercise Professional (EP), plus at least 2 hours weekly unsupervised exercise, over 12- 14 weeks. Assessment was by patient-rated questionnaires addressing function, physical activity, confidence, fatigue and health-related quality of life; objective assessment of gait quality and speed; qualitative individual interviews conducted with participants. Data were collected at baseline, 3 months and 6 months. Fidelity and acceptability was assessed by participant interviews, audit of participant and EP records, and observation of training. FINDINGS: Four of six enrolled participants completed the exercise programme. Quantitative data demonstrated little change across the sample, but marked changes on some measures for some individuals. Qualitative interviews suggested that small benefits in physical outcomes could be of great psychological significance to participants. Participant-reported fatigue levels commonly increased, and non-completers said they found the programme too demanding. Most key components of the intervention were delivered, but there were several potentially important departures from intervention fidelity. DISCUSSION: The study provided data and experience that are helping to inform the design of an RCT of this intervention. It suggested the need for a broader recruitment strategy; indicated areas that could be explored in more depth in the qualitative component of the trial; and highlighted issues that should be addressed to enhance and evaluate fidelity, particularly in the preparation and monitoring of intervention providers. The experience illustrates the value of even small sample before-and-after studies in the development of trials of complex interventions.

Reliability of sonographic assessment of tendinopathy in tennis elbow.

OBJECTIVE: To assess the reliability and compute the minimum detectable change using sonographic scales to quantify the extent of pathology and hyperaemia in the common extensor tendon in people with tennis elbow. MATERIALS AND METHODS: The lateral elbows of 19 people with tennis elbow were assessed sonographically twice, 1-2 weeks apart. Greyscale and power Doppler images were recorded for subsequent rating of abnormalities. Tendon thickening, hypoechogenicity, fibrillar disruption and calcification were each rated on four-point scales, and scores were summed to provide an overall rating of structural abnormality; hyperaemia was scored on a five point scale. Inter-rater reliability was established using the intraclass correlation coefficient (ICC) to compare scores assigned independently to the same set of images by a radiologist and a physiotherapist with training in musculoskeletal imaging. Test-retest reliability was assessed by comparing scores assigned by the physiotherapist to images recorded at the two sessions. The minimum detectable change (MDC) was calculated from the test-retest reliability data. RESULTS: ICC values for inter-rater reliability ranged from 0.35 (95% CI: 0.05, 0.60) for fibrillar disruption to 0.77 (0.55, 0.88) for overall greyscale score, and 0.89 (0.79, 0.95) for hyperaemia. Test-retest reliability ranged from 0.70 (0.48, 0.84) for tendon thickening to 0.82 (0.66, 0.90) for overall greyscale score and 0.86 (0.73, 0.93) for calcification. The MDC for the greyscale total score was 2.0/12 and for the hyperaemia score was 1.1/5. CONCLUSION: The sonographic scoring system used in this study may be used reliably to quantify tendon abnormalities and change over time. A relatively inexperienced imager can conduct the assessment and use the rating scales reliably.

Microcurrent therapy in the management of chronic tennis elbow: pilot studies to optimize parameters.

BACKGROUND AND PURPOSE: In microcurrent therapy (MCT), low-intensity electric current is applied to promote tissue healing and relieve symptoms. MCT is used with recalcitrant skin and bone lesions, but little is known about its effects on tendinopathy, and optimal treatment parameters are uncertain. Two studies were conducted to ascertain whether varying (i) current intensity and (ii) waveform and treatment duration affect outcomes of MCT for chronic tennis elbow. METHODS: Two trials compared the effects of different MCT parameters on pain and function, grip strength, and sonographically graded tendon structure and hyperaemia. Trial 1 compared monophasic MCT of intensity 50 and 500 µA applied for 35 h; trial 2 compared devices delivering approximately 25 µA but with different waveforms and durations of 15 and 189 h, respectively. Treatment was applied over 3 weeks. Assessments were at baseline and 3, 6 and 15 weeks. RESULTS: For each trial, n = 31. In trial 1, 50 µA was more effective than 500 µA, with 93% of participants 'much better' or 'fully recovered' at 15 weeks, compared with 47% in the 500 µA group. Tendon structural normalization was superior at 50 µA, but no significant differences were found in other outcomes. In trial 2, success rates for the two groups at 15 weeks were 75% and 73%, respectively, but group improvements did not differ significantly on any measure. Pooled analysis of data from both trials showed that, immediately following treatment, blood flow had fallen in the subgroup with high baseline scores and risen in the subgroup with low scores. Low baseline score correlated significantly with treatment success. CONCLUSION: Monophasic MCT of peak current intensity 50 µA applied for tens of hours may be effective in reducing symptoms and promoting tendon normalization in chronic tennis elbow. Hyperaemia may help predict treatment outcome. A full-scale trial of the therapy is warranted.

Frailty scales--their potential in interprofessional working with older people: a discussion paper.

New models of interprofessional working are continuously being proposed to address the burgeoning health and social care needs of older people with complex and long-term health conditions. Evaluations of the effectiveness of these models tend to focus on process measures rather than outcomes for the older person. This discussion paper argues that the concept of frailty, and measures based on it, may provide a more user-centred tool for the evaluation of interprofessional services - a tool that cuts across unidisciplinary preoccupations and definitions of effectiveness. Numerous frailty scales have been developed for case identification and stratification of risk of adverse outcomes. We suggest that they may also be particularly suitable for evaluating the effectiveness of interprofessional working with community-dwelling older people. Several exemplars of frailty scales that might serve this purpose are identified, and their potential contributions and limitations are discussed. Further work is required to establish which is the most suitable scales for this application. The development of an appropriate frailty scale could provide an opportunity for interprofessional debate about the forms of care and treatment that should be prioritised to improve the health and well-being of this population.
