The MoXFo initiative - study design: Considerations related to study design and methodology in exercise research for people with multiple sclerosis.

BACKGROUND: Exercise as a subset of physical activity is a cornerstone in the management of multiple sclerosis (MS) based on its pleiotropic effects, but continued progression of the field requires better future designs and methodologies. OBJECTIVES: This paper outlines the work of the 'Study design and methodology' group of the MoXFo (moving exercise research forward) initiative, and addresses critical aspects and future directions when defining the research question of interest, and subsequently, designing the study and exercise intervention in MS patients. METHODS: The work is based on the formation of an international expert panel formed within the MoXFo initiative. We provide a structured and concise synthesis of exercise-specific MS research challenges and considerations when designing randomized controlled trials (RCTs). RESULTS: Challenges and considerations are presented using the Patient population, Intervention, Comparator, Outcomes, Timing, Setting (PICOTS) framework, thereby forming a new and specific MS exercise PICOTS framework. CONCLUSION: We propose that researchers should carefully consider and align all elements of this MS exercise PICOTS framework when developing future research questions and study designs, ultimately improving the quality of new exercise studies in people with MS.

Is Aerobic or Resistance Training the Most Effective Exercise Modality for Improving Lower Extremity Physical Function and Perceived Fatigue in People With Multiple Sclerosis? A Systematic Review and Meta-analysis.

OBJECTIVE: The purpose of this systematic review was to investigate whether aerobic training (AT) or resistance training (RT) is most effective in terms of improving lower limb physical function and perceived fatigue in persons with multiple sclerosis (PwMS). DATA SOURCES: Nine databases (MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health, Allied and Complementary Medicine Database, Physiotherapy Evidence Database, SPORTDiscus, PsycINFO, Web of Science, and Scopus) were electronically searched in April 2020. STUDY SELECTION: Included studies were randomized controlled trials (RCTs) involving PwMS attending 1 of 2 exercise interventions: AT or RT. Studies had to include at least 1 objective or self-reported outcome of lower extremity physical function and/or perceived fatigue. DATA EXTRACTION: Data were extracted using a customized spreadsheet, which included detailed information on patient characteristics, interventions, and outcomes. The methodological quality of the included studies was independently assessed by 2 reviewers using the Tool for Assessment of Study Quality for Reporting on Exercise rating scale. DATA SYNTHESIS: Twenty-seven articles reporting data from 22 RCTS (AT=14, RT=8) including 966 PwMS. The 2 modalities were found to be equally effective in terms of improving short walk test (AT: effect size [ES]=0.33 [95% confidence interval (CI), -1.49 to 2.06]; RT: ES=0.27 [95% CI, 0.07-0.47]) and long walk test performance (AT: ES=0.37 [95% CI, -0.04 to 0.78]; RT: ES=0.36 [95% CI, -0.35 to 1.08]), as well as in reducing perceived fatigue (AT: ES=-0.61 [95% CI, -1.10 to -0.11]; RT: ES=-0.41 [95% CI, -0.80 to -0.02]). Findings on other functional mobility tests along with self-reported walking performance were sparse and inconclusive. CONCLUSIONS: AT and RT appear equally highly effective in terms of improving lower extremity physical function and perceived fatigue in PwMS. Clinicians can thus use either modality to target impairments in these outcomes. In a future perspective, head-to-head exercise modality studies are warranted. Future MS exercise studies are further encouraged to adapt a consensus "core battery" of physical function tests to facilitate a detailed comparison of results across modalities.

Influence of cardiac autonomic neuropathy on cardiac repolarisation during incremental adrenaline infusion in type 1 diabetes.

AIMS/HYPOTHESIS: We examined the effect of a standardised sympathetic stimulus, incremental adrenaline (epinephrine) infusion on cardiac repolarisation in individuals with type 1 diabetes with normal autonomic function, subclinical autonomic neuropathy and established autonomic neuropathy. METHODS: Ten individuals with normal autonomic function and baroreceptor sensitivity tests (NAF), seven with subclinical autonomic neuropathy (SAN; normal standard autonomic function tests and abnormal baroreceptor sensitivity tests); and five with established cardiac autonomic neuropathy (CAN; abnormal standard autonomic function and baroreceptor tests) underwent an incremental adrenaline infusion. Saline (0.9% NaCl) was infused for the first hour followed by 0.01 µg kg-1 min-1 and 0.03 µg kg-1 min-1 adrenaline for the second and third hours, respectively, and 0.06 µg kg-1 min-1 for the final 30 min. High resolution ECG monitoring for QTc duration, ventricular repolarisation parameters (T wave amplitude, T wave area symmetry ratio) and blood sampling for potassium and catecholamines was performed every 30 min. RESULTS: Baseline heart rate was 68 (95% CI 60, 76) bpm for the NAF group, 73 (59, 87) bpm for the SAN group and 84 (78, 91) bpm for the CAN group. During adrenaline infusion the heart rate increased differently across the groups (p = 0.01). The maximum increase from baseline (95% CI) in the CAN group was 22 (13, 32) bpm compared with 11 (7, 15) bpm in the NAF and 10 (3, 18) bpm in the SAN groups. Baseline QTc was 382 (95% CI 374, 390) ms in the NAF, 378 (363, 393) ms in the SAN and 392 (367, 417) ms in the CAN groups (p = 0.31). QTc in all groups lengthened comparably with adrenaline infusion. The longest QTc was 444 (422, 463) ms (NAF), 422 (402, 437) ms (SAN) and 470 (402, 519) ms (CAN) (p = 0.09). T wave amplitude and T wave symmetry ratio decreased and the maximum decrease occurred earlier, at lower infused adrenaline concentrations in the CAN group compared with NAF and SAN groups. AUC for the symmetry ratio was different across the groups and was lowest in the CAN group (p = 0.04). Plasma adrenaline rose and potassium fell comparably in all groups. CONCLUSIONS/INTERPRETATION: Participants with CAN showed abnormal repolarisation in some measures at lower adrenaline concentrations. This may be due to denervation adrenergic hypersensitivity. Such individuals may be at greater risk of cardiac arrhythmias in response to physiological sympathoadrenal challenges such as stress or hypoglycaemia.

Comprehensive geriatric assessment and decision-making in older men with incurable but manageable (chronic) cancer.

PURPOSE: In older cancer patients, treatment decision-making is often complex. A comprehensive geriatric assessment (CGA) is an established tool used in geriatric medicine to identify unmet need requiring intervention. This study aimed to assess whether using a CGA in older male cancer patients with incurable but manageable disease provides information that would alter a cancer clinician's intended management plan. Acceptability and feasibility were secondary aims. METHODS: Elderly men with incurable but manageable malignancies (advanced prostate cancer and multiple myeloma) who had previously received at least one line of treatment were recruited from hospital outpatient clinics. A CGA was undertaken. Additional parameters measuring pain, fatigue and disease-specific concerns were also recorded, at the recommendation of patient involvement groups. Results were made available to clinicians. Patient and clinician acceptability and changes in subsequent management were recorded. RESULTS: Forty-eight patients completed the study. The median ages were 70.8 years and 74 years for myeloma and prostate respectively. Most identified concerns are related to disease-specific concerns (93%), pain (91%), frailty (57%) and nutrition (52%). Results altered the clinician's oncological management plan in nine cases only. Patients found the format and content of CGA acceptable. CONCLUSIONS: Many unmet needs were identified in this population of elderly men with manageable but non curable cancer which led to supportive care referrals and interventions. The CGA, however, did not result in significant changes in clinical oncology treatment plans for the majority of patients. The application of the CGA and other assessments was viewed positively by participants and can feasibly be undertaken in the outpatient oncology setting.

Combined electrical stimulation and exercise for swallow rehabilitation post-stroke: a pilot randomized control trial.

BACKGROUND: Dysphagia is common after stroke, affecting up to 50% of patients initially. It can lead to post-stroke pneumonia, which causes 30% of stroke-related deaths, a longer hospital stay and poorer health outcomes. Dysphagia care post-stroke generally focuses on the management of symptoms, via modified oral intake textures and adapted posture, rather than direct physical rehabilitation of the swallowing function. Transcutaneous neuromuscular electrical stimulation (NMES) is a promising rehabilitation technology that can be used to stimulate swallowing; however, findings regarding efficacy have been conflicting. AIMS: This pilot randomized controlled study involving three UK sites compared the efficacy of the Ampcare Effective Swallowing Protocol (ESP), combining NMES with swallow-strengthening exercises, with usual care in order to clarify evidence on NMES in the treatment of dysphagia post-stroke. A further objective was to pilot recruitment procedures and outcome measures in order to inform the design of a full-scale trial. METHODS & PROCEDURES: Thirty patients were recruited and randomized into either (1) usual speech and language therapy dysphagia care; or (2) Ampcare ESP, receiving treatment 5 days/week for 4 weeks. Outcome measures included: the Functional Oral Intake Scale (FOIS), the Rosenbek Penetration-Aspiration Scale (PAS) and patient-reported outcomes (Swallow Related Quality of Life-SWAL-QOL). OUTCOMES & RESULTS: Thirty patients were recruited; 15 were randomized to the Ampcare ESP intervention arm and 15 to usual care. A greater proportion (75%, or 9/12) of patients receiving Ampcare ESP improved compared with 57% (or 8/14) of the usual-care group. Patients receiving Ampcare ESP also made clinically meaningful change (a comparative benefit of 1.5 on the FOIS, and on the PAS: 1.35 for diet and 0.3 for fluids) compared with usual care. The intervention group also reported much better outcome satisfaction. CONCLUSIONS & IMPLICATIONS: The pilot demonstrated successful recruitment, treatment safety and tolerability and clinically meaningful outcome improvements, justifying progression to a fully powered study. It also showed clinically meaningful treatment trends for the Ampcare ESP intervention.

A Comparison of Measurements of Change in Respiratory Status in Spontaneously Breathing Volunteers by the ExSpiron Noninvasive Respiratory Volume Monitor Versus the Capnostream Capnometer.

BACKGROUND: Current respiratory monitoring technologies such as pulse oximetry and capnography have been insufficient to identify early signs of respiratory compromise in nonintubated patients. Pulse oximetry, when used appropriately, will alert the caregiver to an episode of dangerous hypoxemia. However, desaturation lags significantly behind hypoventilation and alarm fatigue due to false alarms poses an additional problem. Capnography, which measures end-tidal CO2 (EtCO2) and respiratory rate (RR), has not been universally used for nonintubated patients for multiple reasons, including the inability to reliably relate EtCO2 to the level of impending respiratory compromise and lack of patient compliance. Serious complications related to respiratory compromise continue to occur as evidenced by the Anesthesiology 2015 Closed Claims Report. The Anesthesia Patient Safety Foundation has stressed the need to improve monitoring modalities so that "no patient will be harmed by opioid-induced respiratory depression." A recently available, Food and Drug Administration-approved noninvasive respiratory volume monitor (RVM) can continuously and accurately monitor actual ventilation metrics: tidal volume, RR, and minute ventilation (MV). We designed this study to compare the capabilities of capnography versus the RVM to detect changes in respiratory metrics. METHODS: Forty-eight volunteer subjects completed the study. RVM measurements (MV and RR) were collected simultaneously with capnography (EtCO2 and RR) using 2 sampling methods (nasal scoop cannula and snorkel mouthpiece with in-line EtCO2 sensor). For each sampling method, each subject performed 6 breathing trials at 3 different prescribed RRs (slow [5 min], normal [12.6 ± 0.6 min], and fast [25 min]). All data are presented as mean ± SEM unless otherwise indicated. RESULTS: Following transitions in prescribed RRs, the RVM reached a new steady state value of MV in 37.7 ± 1.4 seconds while EtCO2 changes were notably slower, often failing to reach a new asymptote before a 2.5-minute threshold. RRs as measured by RVM and capnography during steady breathing were strongly correlated (R = 0.98 ± 0.01, bias = Capnograph-based RR - RVM-based RR = 0.21 ± 1.24 [SD] min). As expected, changes in MV were negatively correlated with changes in EtCO2. However, large changes in MV following transitions in prescribed RR resulted in relatively small changes in EtCO2 (instrument sensitivity = ΔEtCO2/ΔMV = -0.71 ± 0.11 and -0.55 ± 0.11 mm Hg per 1 L/min for nasal and in-line sampling, respectively). Nasal cannula EtCO2 measurements were on average 4 mm Hg lower than in-line measurements. CONCLUSIONS: RVM measurements of MV change more rapidly and by a greater degree than capnography in response to respiratory changes in nonintubated patients. Earlier detection could enable earlier intervention that could potentially reduce frequency and severity of complications due to respiratory depression.

The organisation of physiotherapy for people with multiple sclerosis across Europe: a multicentre questionnaire survey.

BACKGROUND: Understanding the organisational set-up of physiotherapy services across different countries is increasingly important as clinicians around the world use evidence to improve their practice. This also has to be taken into consideration when multi-centre international clinical trials are conducted. This survey aimed to systematically describe organisational aspects of physiotherapy services for people with multiple sclerosis (MS) across Europe. METHODS: Representatives from 72 rehabilitation facilities within 23 European countries completed an online web-based questionnaire survey between 2013 and 2014. Countries were categorised according to four European regions (defined by United Nations Statistics). Similarities and differences between regions were examined. RESULTS: Most participating centres specialized in rehabilitation (82 %) and neurology (60 %), with only 38 % specialising in MS. Of these, the Western based Specialist MS centres were predominately based on outpatient services (median MS inpatient ratio 0.14), whilst the Eastern based European services were mostly inpatient in nature (median MS inpatient ratio 0.5). In almost all participating countries, medical doctors - specialists in neurology (60 %) and in rehabilitation (64 %) - were responsible for referral to/prescription of physiotherapy. The most frequent reason for referral to/prescription of physiotherapy was the worsening of symptoms (78 % of centres). Physiotherapists were the most common members of the rehabilitation team; comprising 49 % of the team in Eastern countries compared to approximately 30 % in the rest of Europe. Teamwork was commonly adopted; 86 % of centres based in Western countries utilised the interdisciplinary model, whilst the multidisciplinary model was utilised in Eastern based countries (p = 0.046). CONCLUSION: This survey is the first to provide data about organisational aspects of physiotherapy for people with MS across Europe. Overall, care in key organisational aspects of service provision is broadly similar across regions, although some variations, for example the models of teamwork utilised, are apparent. Organisational framework specifics should be considered anytime a multi-centre study is conducted and results from such studies are applied.

The evaluation of a non-invasive respiratory volume monitor in surgical patients undergoing elective surgery with general anesthesia.

Continuous respiratory assessment is especially important during post-operative care following extubation. Respiratory depression and subsequent adverse outcomes can arise due to opioid administration and/or residual anesthetics. A non-invasive respiratory volume monitor (RVM) has been developed that provides continuous, real-time, measurements of minute ventilation (MV), tidal volume (TV), and respiratory rate (RR) via a standardized set of thoracic electrodes. Previous work demonstrated accuracy of the RVM versus standard spirometry and its utility in demonstrating response to opioids in postoperative patients. This study evaluated the correlation between RVM measurements of MV, TV and RR to ventilator measurements during general anesthesia (GA). Continuous digital RVM and ventilator traces, as well as RVM measurements of MV, TV and RR, were analyzed from ten patients (mean 62.6±7.4 years; body mass index 28.6±5.2 kg/m2) undergoing surgery with GA. RVM data were compared to ventilator data and bias, precision and accuracy were calculated. The average MV difference between the RVM and ventilator was -0.10 L/min (bias: -1.3%, precision: 6.6%, accuracy: 9.0%. The average TV difference was 40 mL (bias: 0.4%, precision: 7.3%, accuracy: 9.1%). The average RR difference was -0.22 breaths/minute (bias: -1.8%, precision: 3.7% accuracy: 4.1%). Correlations between the RVM traces and the ventilator were compared at various points with correlations>0.90 throughout. Pairing the close correlation to ventilator measurements in intubated patients demonstrated by this study with previously described accuracy compared to spirometry in non-intubated patients, the RVM can be considered to have the capability to provide continuity of ventilation monitoring post-extubation This supports the use of real-time continuous RVM measurements to drive post-operative and post-extubation protocols, initiate therapeutic interventions and improve patient safety.

Levels of distress in breast cancer survivors approaching discharge from routine hospital follow-up.

BACKGROUND: Hospital-based breast cancer follow-up provides reassurance to patients despite limited evidence for clinical efficacy. Although alternative models of hospital/community-based follow-up have yielded encouraging results, traditional hospital follow-up continues to be offered to all patients. Survival rates continue to rise; consequently, more patients are likely to require support, as many have a limited understanding of the long-term physical and emotional consequences of cancer and its treatment. We examine levels of psychological distress in breast cancer patients in follow-up 2 years or more from diagnosis. METHODS: This prospective study measured psychological distress levels using standardized measures [Hospital Anxiety and Depression Scale (HADS), Clinical Outcomes for Routine Evaluation (CORE) and Measure Yourself Medical Outcomes Profile (MYMOP)]. Between January and September 2008, 323 consecutive patients were approached in outpatient clinics. Ninety-six patients declined to participate. RESULTS: Two hundred twenty-seven patients took home patient information sheets; 172 (75%) returned completed questionnaires to assess levels of distress (HADS, CORE). MYMOP provided self-reported data on patient symptoms. Patients reported low levels of distress in hospital-based follow-up, which were comparable or better than general population norms, although there was a significant minority of patients reporting high scores (n = 27, 15.7%) on HADS or CORE. There was good agreement between these two measures. All sub-scales of CORE (except risk) correlated well with HADS for anxiety/depression. No significant changes were detected in the standardized measures. MYMOP results showed that 23.8% of respondents reported both physical and emotional symptoms. CONCLUSIONS: Breast cancer survivors reported good psychological outcomes 2 years on from diagnosis. Screening for psychological/emotional distress is a vital part of follow-up care, which should be incorporated into UK policy.

Special article: evaluation of a novel noninvasive respiration monitor providing continuous measurement of minute ventilation in ambulatory subjects in a variety of clinical scenarios.

BACKGROUND: Currently there is no technology that noninvasively measures the adequacy of ventilation in nonintubated patients. A novel, noninvasive Respiratory Volume Monitor (RVM) has been developed to continuously measure and display minute ventilation (MV), tidal volume (TV), and respiratory rate (RR) in a variety of clinical settings. We demonstrate the RVM's accuracy and precision as compared with a standard spirometer under a variety of clinically relevant breathing patterns in nonintubated subjects. METHODS: Thirty-one voluntary subjects completed the primary study. MV, TV, and RR measurements were collected from the RVM and spirometer simultaneously for each participant on day 1 and day 2 and analyzed to determine accuracy, precision, and bias for normal, fast, slow, irregular, and closed-glottis breathing. RESULTS: Data demonstrated that RVM and spirometer measurements of MV and TV are equivalent in a wide range of ambulatory subjects with an average error <10% (95% confidence interval for accuracy <16%, precision <12%, and bias <11%). Repeated measures analysis of variance found no significant difference between spirometry and RVM individual measurements of MV, TV, and RR (P > 0.7), whereas a paired-difference equivalent test demonstrated, with 99% power, that both MV and TV measurements from the 2 devices are equivalent within ±15%. CONCLUSIONS: This study demonstrates RVM's clinically relevant accuracy and precision in measuring MV, TV, and RR over a 24-hour period and during various breathing patterns.

Learn something new in 20 minutes: Bite Size sessions to support research and teaching.

The School of Health and Related Research (ScHARR) at The University of Sheffield run an innovative series of informal 20-minute Bite Size sessions to help staff and students teach, research, collaborate and communicate more effectively. The sessions have two clear strands: one focused on teaching and the other on research. The remit is not to teach people how to use something in their work or study, but to let them know why they should use it and how they can employ it. By introducing participants to the possibilities and how they can apply ideas and technologies in their work and study in an enthusiastic manner, it is possible to send them away with at least the intention to explore and experiment. The evidence shows that this organic approach is working--staff and students are starting to use many of the tools that Bite Size has covered. Any kind of widespread change within organisations can be hard to deliver, but by bringing champions on your side and delivering sessions in a convenient, informal and timely manner; good practice and ideas can spread naturally.

Telerehabilitation for people with physical disabilities and movement impairment: development and evaluation of an online toolkit for practitioners and patients.

PURPOSE: Telerehabilitation has increasingly been used since the COVID-19 pandemic but with limited guidance available on undertaking physical assessments using remote methods. We aimed to provide such guidance by developing a Telerehab Toolkit, an online information and training resource for practitioners, patients, and carers on telerehabilitation for people with physical disabilities and movement impairment. MATERIALS AND METHODS: Development and evaluation of the toolkit were informed by the Knowledge to Action framework and took place iteratively in two phases-knowledge creation and action. Information was collated from various sources including literature review, online survey, service evaluation, and focus group discussions. The toolkit has been evaluated using think-aloud interviews, e-mail and social media feedback from users, and analytics data on user engagement with the website. RESULTS: The Telerehab Toolkit focuses on remote physical assessments, and contains information on technology, digital skills, remote assessment tools, information governance, and safety for telerehabilitation. Resources include top tips from practitioners and patients, how-to guides, checklists, videos, and links to evidence. CONCLUSIONS: The Telerehab Toolkit has been well-received by practitioners, healthcare students, patients, and carers, is being disseminated widely, and is freely available (www.plymouth.ac.uk/research/telerehab). IMPLICATIONS FOR REHABILITATIONTelerehabilitation has been increasingly used since the COVID-19 pandemic, but with limited guidance and training for practitioners on undertaking safe and effective remote physical assessments.The Telerehab Toolkit has been developed iteratively using the Knowledge to Action framework; it is a free online resource for practitioners and patients with specific guidance on telerehabilitation for physical disabilities and movement impairment.It is anticipated that the resource will help to improve the knowledge, skills, and confidence of the current and future rehabilitation workforce.

An observational study to assess validity and reliability of smartphone sensor-based gait and balance assessments in multiple sclerosis: Floodlight GaitLab protocol.

Background: Gait and balance impairments are often present in people with multiple sclerosis (PwMS) and have a significant impact on quality of life and independence. Gold-standard quantitative tools for assessing gait and balance such as motion capture systems and force plates usually require complex technical setups. Wearable sensors, including those integrated into smartphones, offer a more frequent, convenient, and minimally burdensome assessment of functional disability in a home environment. We developed a novel smartphone sensor-based application (Floodlight) that is being used in multiple research and clinical contexts, but a complete validation of this technology is still lacking. Methods: This protocol describes an observational study designed to evaluate the analytical and clinical validity of Floodlight gait and balance tests. Approximately 100 PwMS and 35 healthy controls will perform multiple gait and balance tasks in both laboratory-based and real-world environments in order to explore the following properties: (a) concurrent validity of the Floodlight gait and balance tests against gold-standard assessments; (b) reliability of Floodlight digital measures derived under different controlled gait and balance conditions, and different on-body sensor locations; (c) ecological validity of the tests; and (d) construct validity compared with clinician- and patient-reported assessments. Conclusions: The Floodlight GaitLab study (ISRCTN15993728) represents a critical step in the technical validation of Floodlight technology to measure gait and balance in PwMS, and will also allow the development of new test designs and algorithms.

Telerehabilitation for physical disabilities and movement impairment: A service evaluation in South West England.

RATIONALE, AIMS AND OBJECTIVES: Telerehabilitation was used to ensure continued provision of care during the COVID-19 pandemic, but there was a lack of guidance on how to use it safely and effectively for people with physical disabilities and movement impairment. In this service evaluation, we aimed to collate information on practitioner and patient experiences, challenges and facilitators, and examples of best practice to inform the development of an online toolkit and training package. METHODS: Guided discussions were carried out with 44 practitioners, 7 patients and 2 carers from five health and social care organisations in South West England, and analysed thematically. RESULTS: Practitioners and patients had positive experiences of telerehabilitation and were optimistic about its future use. Recognized benefits for people with physical disabilities included greater flexibility, reduced travel and fatigue, having appointments in a familiar environment and ease of involving family members. Challenges encountered were: technological (usability issues, access to technology and digital skills); difficulties seeing or hearing patients; the lack of 'hands-on' care; and safety concerns. Facilitators were supported by colleagues or digital champions, and family members or carers who could assist patients during their appointments. Key themes in best practice were: person-centred and tailored care; clear and open communication and observation and preparation and planning. Practitioners shared tips for remote physical assessments; for example, making use of patient-reported outcomes, and asking patients to wear bright and contrasting coloured clothing to make it easier to see movement. CONCLUSION: Telerehabilitation holds promise in health and social care, but it is necessary to share good practice to ensure it is safe, effective and accessible. We collated information and recommendations that informed the content of the Telerehab Toolkit (https://www.plymouth.ac.uk/research/telerehab), a practical resource for practitioners, patients and carers, with a focus on remote assessment and management of physical disabilities and movement impairment.

The impact of the 4 h target on patient care and outcomes in the Emergency Department: an analysis of hospital incidence data.

BACKGROUND: Recent government initiatives in the NHS have seen patient care becoming increasingly target-driven. However, the impact of targets, particularly those based on a timeframe, have not been extensively studied, and concerns remain about unintended consequences for patients. The aim of this study was to evaluate the effect of a 4 h target in the Emergency Department (ED) on patient care and outcomes. METHODS: The study comprised an interrupted time-series regression analysis of anonymised patient-level data from 580,000 new patient episodes in the ED between April 2000 and Feb 2006. Outcomes were time in ED, time to clinician, mortality, admission and reattendance rates, and number of investigations. RESULTS: 90% target was associated with reductions in time in department and fewer patients admitted for less than 24 and 48 h, and a slight increase in the number reattending within 7 days. 98% target was associated with levelling-off of time in department and reductions in numbers admitted and reattending within 7 days. Neither target was associated with change in time to clinician. The introduction of a minor injuries unit (MIU) was associated with reductions in time to clinician and percentage not waiting, and increases in number of investigations, percentages admitted, admitted for 24 h and reattendances within 7 days. Mortality was unaffected by either target or MIU. CONCLUSION: Although time target introduction is associated with changes in patient care, the introduction of a co-located MIU had greater impact.

Assessing lower limb position sense in stroke using the gradient discrimination test (GradDT™) and step-height discrimination test (StepDT™): a reliability and validity study.

Purpose: To evaluate the psychometric properties of two novel tests of lower limb position sense.Methods: Our newly developed tests assess the discrimination thresholds of under-foot slope and step height perception using a two alternative forced choice approach. Stroke participants (n = 32) and age matched controls (n = 32) were tested. Inter- and intra-rater reliability and agreement, sensitivity and specificity, discriminant and convergent validity were evaluated.Results: Intra-rater reliability for both variants of the gradient discrimination test was excellent; intraclass correlation coefficients (ICC) =0.91 and 0.89. The step height discrimination test had excellent intra-rater reliability and agreement: ICC =0.95. Inter-rater reliability was also excellent in both tests (ICC= 0.85-0.93). Discriminant validity was demonstrated with significant differences in test performance between stroke and control participants (p < 0.001). Our novel tests did not significantly correlate with the proprioceptive component of the Erasmus modified Nottingham Sensory Assessment. Receiver Operating Characteristic curve analysis indicated both novel tests to have greater sensitivity and specificity than the proprioceptive component of the Erasmus modified Nottingham Sensory Assessment in predicting the presence of self-reported sensory impairments. Functional reach test, 10 meter walk test, centre of pressure measurement and reported falls showed significant and moderate to strong correlations with novel test performance (r = 0.40-0.60); the Erasmus modified Nottingham Sensory Assessment did not.Conclusions: Our novel, functionally oriented tests of lower limb position sense are reliable, valid and feasible for use in an ambulatory chronic stroke and elderly population.Implications for rehabilitationThe GradDT™ and StepDT are two novel tests of lower limb position sense which are reliable and valid in a chronic stroke sample.They offer clinicians and researchers sensitive, accurate and clinically usable measures of lower limb position sense.

Real-World Goal Setting and Use of Outcome Measures According to the International Classification of Functioning, Disability and Health: A European Survey of Physical Therapy Practice in Multiple Sclerosis.

Goal setting is a core component of physical therapy in multiple sclerosis (MS). It is unknown whether and to what extent goals are set at different levels of the International Classification of Functioning, Disability and Health (ICF), and whether, and to which, standardized outcome measures are used in real life for evaluation at the different ICF levels. Our aim was to describe the real-world use of goal setting and outcome measures in Europe. An online cross-sectional survey, completed by 212 physical therapists (PTs) specialized in MS from 26 European countries, was conducted. Differences between European regions and relationships between goals and assessments were analyzed. PTs regularly set goals, but did not always apply the Specific, Measurable, Achievable, Realistic, Timed (SMART) criteria. Regions did not differ in the range of activities assessed, but in goals set (e.g., Western and Northern regions set significantly more goals regarding leisure and work) and outcome measures used (e.g., the Berg Balance Scale was more frequently used in Northern regions). Quality of life was not routinely assessed, despite being viewed as an important therapy goal. Discrepancies existed both in goal setting and assessment across European regions. ICF assists in understanding these discrepancies and in guiding improved health-care for the future.

Content and Delivery of Physical Therapy in Multiple Sclerosis across Europe: A Survey.

Background: Guidelines and general recommendations are available for multiple sclerosis rehabilitation, but no specific guidance exists for physical therapists. Describing aspects of physical therapy content and delivery in multiple sclerosis and its determinants and analysing whether general recommendations connected with physical therapy are implemented in practice is important for interpreting clinical and research evidence. Methods: An online cross-sectional survey of physical therapists specialized in multiple sclerosis (212 specialists from 26 European countries) was used. Results: There was distinct diversity in service delivery and content across Europe. Perceived accessibility of physical therapy varied from most accessible in the Western region, and least in the Southern region. Sixty-four physical therapists adjusted their approach according to different disability levels, less so in the Eastern region. Duration, frequency and dose of sessions differed between regions, being highest in Southern and Western regions. "Hands on treatment" was the most commonly used therapeutic approach in all apart from the Northern regions, where "word instruction" (providing advice and information) prevailed. Conclusions: The content and delivery of physical therapy differs across Europe. Recommendations concerning access to treatment and adjustment according to disability do not appear to be widely implemented in clinical practice.
