Assessment of fracture risk tools in care home residents: a multi-centre observational pilot study.

BACKGROUND: Fragility fractures are common in care home residents but established tools have not been tested in this population. AIM: To identify the most practicable tool for use. METHODS: DESIGN: Multicentre prospective observational cohort pilot study. SETTING: 18 care homes in Boston, UK. ASSESSMENTS: fragility risk score at baseline with FRAX, QFractureScore, Garvan nomogram, body mass index and TUGT for each participant. OUTCOMES: falls, fractures, combined falls & fractures. Follow-up; 12 months. RESULTS: 217/618 (35%) residents in the 18 care homes were enrolled. 147 (68%) had mental capacity,70 (32%) did not. There were 325 falls and 10 fractures in participants during the study. At the same time there were 1671 falls and 103 fractures in residents not participating in the study. Multiple regression analyses showed that only age had a statistically significant association with falls (χ2(1) = 5.7775, p = 0.0162), fractures (χ2(1) = 4.7269, p = 0.0297) and combined falls & fractures (χ2(1) = 4.7269, p = 0.0297). C-statistics were: falls; FRAX 0.544, BMI 0.610, QFractureScore 0.554, Garvan nomogram 0.579, TUGT 0.656, fractures; FRAX 0.655, BMI 0.708, QFractureScore 0.736, Garvan nomogram 0.712, TUGT 0.590, combined falls and fractures, c-statistics were same as for fractures. Fifty-four participants (25%) died during follow-up. Charlson comorbidity index predicted mortality, R2 = 0.021 (p = 0.034). CONCLUSIONS: QFractureScore, BMI and Garvan nomogram were good predictors of fractures and combined falls and fractures Only age had statistically significant association with the outcomes. No tool was good predictor of falls

An exploration of stakeholders’ perceptions of the barriers to clinical use of Assistive Technologies in services for upper-limb stroke rehabilitation

Introduction Half of all patients commencing stroke rehabilitation have marked impairment of the hemiplegic arm, with only 14% regaining useful function. Assistive technologies (ATs) have been developed and evaluated yet currently reach only a fraction of patients. The NIHR funded a five year research programme to generate understanding necessary to develop cost-effective stroke services in upper-limb rehabilitation. This stage aims to understand the potential advantages and disadvantages to the clinical use of ATs, and the needs and priorities of stakeholders. Method Participants include people with a stroke (n=40), their carers (n=20), health care professionals (n= 40), budget holders (n=15) and service commissioners (n=15). An interactive exhibition was held at the University of Southampton in October 2009 where stakeholders tested a range of ATs. Focus groups with each stakeholder group will be conducted within three months of the exhibition to discuss personal involvement in AT use, and positive and negative views on the AT presented. Results Results will be categorised in terms of barriers and facilitators to the use of upper-limb technologies addressing issues such as user comfort and acceptability, cost-benefit, evidence of effect and funding provision. Conclusion Getting research implemented in practice is challenging. This novel approach explores the barriers to using new technologies from the perspective of all key stakeholders. These findings will be combined with those of a national survey, and systematic review to inform a clinical trial resulting in a recommended care pathway for upper-limb rehabilitation

A pilot study of a single intermittent arm cycling exercise programme on people affected by Facioscapulohumeral dystrophy (FSHD)

For patients affected by Facioscapulohumeral dystrophy (FSHD), alternate methods for increasing physical activity engagement that may benefit shoulder function and wider health are needed. Arm cycling has been proposed as a potential method for achieving this although dosage parameters and evidence is limited. The aim of this study was to conduct a pilot study evaluating the effect of a single intermittent arm cycling exercise programme on people affected by FSHD. People with confirmed genetic diagnosis of FSHD between the ages 18–60 years were recruited to attend a single session for the exercise intervention (5 exercise efforts lasting 2 minutes each with 30 seconds of rest between each effort). Prior to exercise, measures of shoulder function (Oxford shoulder score), strength and range of movement were recorded. During the exercise participants were video recorded to quantify range of movement and extract movement profile features. Participants comments were recorded and followed up four days later to check for adverse events. Fifteen participants, (6F:9M) were recruited with median (IQR) Oxford Shoulder Scores of 25 (18 to 39). All participants successfully completed the exercise intervention with only transient symptoms consistent with exercise being reported and achieving a median (IQR) rate of perceived exertion scores of 13 (12 to 13). Movement profile data was available for 12 out of 15 participants and suggests that exercise intensity did not compromise movement. An association between strength and shoulder function (R2 = 0.5147), Rate of perceived exertion (RPE) of the final effort against shoulder function and strength (R2 = 0.2344 and 0.1743 respectively) was identified. Participant comments were positive regarding the exercise intervention. Our study demonstrates that an intermittent arm cycling programme is feasible for people affected by FSHD. Further work is needed to evaluate physiological responses to exercise across variations in programme variables and equipment set up in a larger sample of people affected by FSHD.Funder: The Orthopaedic Institute Limited; Grant(s): RPG16

Estimating the cost consequence of the early use of botulinum toxin in post-stroke spasticity: Secondary analysis of a randomised controlled trial.

OBJECTIVE: To estimate the cost-consequence of treating spasticity early with botulinum toxin in the acute stroke unit. DESIGN: Secondary cost-consequence analysis, using data from a double-blind randomised-controlled trial. SETTING: Single-centre specialised stroke unit. SUBJECTS AND INTERVENTIONS: Patients with Action Research Arm Test grasp-score of <2 and who developed spasticity within six weeks of a first stroke were randomised to receive injections of: 0.9% sodium-chloride solution (placebo) or onabotulinumtoxin-A (treatment). MAIN MEASURES: Resource use costs were calculated for the study. Mean contracture costs for each group were calculated. The Barthel Index and Action Research Arm Test were used to generate a cost per unit of improvement. RESULTS: There were no significant differences associated with early treatment use. The mean contracture cost for the treatment group was £817 and for the control group was £2298 (mean difference = -£1481.1(95% CI -£2893.5, -£68.7) (p = 0.04). The cost per unit of improvement for the Barthel Index was -£1240 indicating that the intervention costs less and is more effective. The cost per unit of improvement for the Action Research Arm Test was -£450 indicating that the intervention costs less and is more effective. CONCLUSIONS: Treating spasticity early in stroke patients at risk of contractures with botulinum toxin leads to a significant reduction in contracture costs. The cost per improvement of Barthel and Action Research Arm Test indicates that the intervention costs less and is more effective.

Quantifying Missingness in Wearable Heart Rate Recordings.

Wrist-worn photoplethysmography (PPG) heart rate monitoring devices are increasingly used in clinical applications despite the potential for data missingness and inaccuracy. This paper provides an analysis of the intermittency of experimental wearable data recordings. Devices recorded heart rate with gaps of 5 or more minutes 41.6% of the time and 15 or more minutes 3.8% of the time

A Scoping Literature Review of Studies Assessing Effectiveness and Cost-Effectiveness of Prosthetic and Orthotic Interventions

Purpose: Approximately 1.5% of the world’s population (~100 million people) need a prosthesis/orthosis. The objective of the study was to establish an overview of the literature that has examined prosthetic and orthotic interventions with a view to inform policy development. Methods: Fourteen databases were searched from 1995-2015. Studies reporting primary research on the effectiveness or cost-effectiveness of prosthetic and orthotic interventions were examined. Metadata and information on study characteristics were extracted from the included studies. Results: The searches resulted in a total of 28,958 articles, a focus on studies with the words “randomised” OR “randomized” OR “cost” OR “economic” in their citation reduced this total to 2,644. Research has predominantly been conducted in Australia, Canada, Germany, Netherlands, UK and USA. 346 randomised controlled trials were identified, with only four randomised controlled trials examining prosthetic interventions. The majority of research examined lower limb orthoses in the adult population and used a wide range of outcome measures. Conclusions: While various international organisations have highlighted the value of providing prosthetic and orthotic services, both to the user and society as a whole, the availability of scientific research to inform policy is limited. Future structured evaluation of prosthetic and orthotic interventions/services is warranted to inform future policy developments

Improving predictor selection for injury modelling methods in male footballers.

Objectives: This objective of this study was to evaluate whether combining existing methods of elastic net for zero-inflated Poisson and zero-inflated Poisson regression methods could improve real-life applicability of injury prediction models in football. Methods: Predictor selection and model development was conducted on a pre-existing dataset of 24 male participants from a single English football team's 2015/2016 season. Results: The elastic net for zero-inflated Poisson penalty method was successful in shrinking the total number of predictors in the presence of high levels of multicollinearity. It was additionally identified that easily measurable data, that is, mass and body fat content, training type, duration and surface, fitness levels, normalised period of 'no-play' and time in competition could contribute to the probability of acquiring a time-loss injury. Furthermore, prolonged series of match-play and increased in-season injury reduced the probability of not sustaining an injury. Conclusion: For predictor selection, the elastic net for zero-inflated Poisson penalised method in combination with the use of ZIP regression modelling for predicting time-loss injuries have been identified appropriate methods for improving real-life applicability of injury prediction models. These methods are more appropriate for datasets subject to multicollinearity, smaller sample sizes and zero-inflation known to affect the performance of traditional statistical methods. Further validation work is now required

Available tools to evaluate digital health literacy and engagement with eHealth resources: A scoping review

Background: As eHealth and use of information and communication technologies (ICT) within healthcare becomes widespread, it is important to ensure that these forms of healthcare are accessible to the users. One factor that is key to accessing eHealth is digital health literacy. Objectives: This scoping review assesses available tools that can be used to evaluate digital health literacy. Methods: A systematic literature search was made in MEDLINE, CINAHL, APA PsychInfo, Ageline, AMED, and APA PsychArticles to present the tools currently in use to assess digital health literacy. A qualitative synthesis of the evidence was carried out using a data charting form created for this review. Extracted data included details of the population of investigation and digital health literacy tool used. A report was produced following PRISMA-ScR guidelines. Results: In total, 53 papers with adult participants and 3 with adolescent participants (aged between 12 and 19 years) were included in the scoping review. 5 questionnaires were identified that measured digital health literacy or attitudes towards the internet, of which the eHealth Literacy Scale (eHEALS) was the most commonly used questionnaire for both adults and children. Two children's questionnaires were often accompanied by a second task to verify the accuracy of the responses to the eHEALS questions. Conclusions: eHEALS is the most commonly used method to assess digital health literacy and assess whether an individual is able to engage actively with eHealthcare or virtual resources. However, care needs to be taken to ensure that its administration does not exclude digitally disadvantaged groups from completing it. Future research would benefit from assessing whether digital health literacy tools are appropriate for use in clinical settings, working to ensure that any scales developed in this area are practical and can be used to support the allocation of resources to ensure that people are able to access healthcare equitably
