Learning about COVID-19 across borders: public health information and adherence among international travellers to the UK.

OBJECTIVE: Public health control measures at borders have long been central to national strategies for the prevention and containment of infectious diseases. Travel was inevitably associated with the rapid global transmission of COVID-19. In the UK, public health authorities tried to reduce the risks of travel-associated spread by providing public health information at ports of entry. This study investigates risk assessment processes, decision-making and adherence to official advice among international travellers, to provide evidence for future policy on the provision of public health information to facilitate safer international travel. STUDY DESIGN: This study is a qualitative study evaluation. METHOD: International air passengers arriving at the London Heathrow Airport on scheduled flights from China and Singapore were approached for interview after consenting to contact in completed surveys. Semi-structured interviews were conducted by telephone, using two topic guides to explore views of official public health information and self-isolation. Interview transcripts were coded and analysed thematically. RESULTS: Participants regarded official advice from Public Health England as adequate at the time, despite observing differences with intervention measures implemented in their countries of departure. Most participants also described adopting precautionary measures, including self-isolation and the use of face coverings that went beyond official advice, but reported adherence to guidance on contacting health authorities was more variable. Adherence to the official guidance was informed by the perceived salience of specific transmission possibilities and containment measures assessed in relation to participants' local social and institutional environments. CONCLUSION: Analysis of study findings demonstrates that international air travellers' responses to public health advice constitute a proactive process of risk assessment and rationalised decision-making to guide preventive action. This process incorporates consideration of the current living situation, trust in information sources, correspondence with cultural logics and willingness to accept potential risk to self and significant others. Our findings concerning international passengers' understanding of, and compliance with, official advice and mitigation measures provide valuable evidence to inform future policy and generate recommendations on the presentation of public health information to facilitate safer international travel. Access to a central source of regularly updated official information would help minimise confusion between different national guidelines. Greater attention to the differentiated information needs of diverse groups in creating future public-facing guidance would help to minimise the uncertainties generated by the receipt of generic information.

Views and experiences of managing eczema: systematic review and thematic synthesis of qualitative studies.

BACKGROUND: The number of qualitative studies on eczema has increased rapidly in recent years. Systematically reviewing these can provide greater understandings of people's perceptions of eczema and eczema treatments. OBJECTIVES: We sought to systematically review and thematically synthesize qualitative studies exploring views and experiences of people with eczema and parents/carers of children with eczema. METHODS: We searched MEDLINE, EMBASE, PsycINFO and CINAHL from the earliest date available to February 2019. We selected papers focusing on views and experiences of eczema and eczema treatments, and barriers/facilitators to eczema self-management. We excluded papers focusing on health service provision models or health professionals' views. RESULTS: We synthesized 39 papers (reporting 32 studies) from 13 countries. We developed four analytical themes: (1) Eczema not viewed as a long-term condition; (2) Significant psychosocial impact not acknowledged by others; (3) Hesitancy (patient/carer uncertainty) about eczema treatments; and (4) Insufficient information and advice. Our findings suggest that people with eczema and their carers experience frustration at having to manage a condition that is often seen by others as mundane but has significant psychosocial impact and is difficult to manage due to concerns about, and burden of, treatment. This frustration can be exacerbated by experiences of conflicting and/or insufficient information and advice from health professionals, family and others. CONCLUSIONS: Effective self-management of eczema could be supported by addressing beliefs and concerns about treatments; seeking positive ways to promote a 'control not cure' message; acknowledging psychosocial impacts of eczema and treatment burden; and providing clear consistent advice or signposting towards reliable information.

Public health information on COVID-19 for international travellers: lessons learned from a mixed-method evaluation.

OBJECTIVES: In the containment phase of the response to the COVID-19 outbreak, Public Health England (PHE) delivered advice to travellers arriving at major UK ports. We aimed to rapidly evaluate the impact and effectiveness of these communication materials for passengers in the early stages of the pandemic. STUDY DESIGN: The study design used is the mixed-methods evaluation. METHODS: A questionnaire survey and follow-up interviews with passengers arriving at London Heathrow Airport on scheduled flights from China and Singapore. The survey assessed passengers' knowledge of symptoms, actions to take, and attitudes towards PHE COVID-19 public health information; interviews explored their views of official public health information and self-isolation. RESULTS: One hundred and twenty-one passengers participated in the survey and 15 in follow-up interviews. Eighty three percentage of surveyed passengers correctly identified all three COVID-19 associated symptoms listed in PHE information at that time. Most could identify the recommended actions and found the advice understandable and trustworthy. Interviews revealed that passengers shared concerns about the lack of wider official action, and that passengers' knowledge had been acquired elsewhere as much from PHE. Respondents also noted their own agency in choosing to self-isolate, partially as a self-protective measure. CONCLUSION: PHE COVID-19 public health information was perceived as clear and acceptable, but we found that passengers acquired knowledge from various sources and they saw the provision of information alone on arrival as an insufficient official response. Our study provides fresh insights into the importance of taking greater account of diverse information sources and of the need for public assurance in creating public health information materials to address global health threats.

Beliefs about inevitable decline among home-living older adults at risk of malnutrition: a qualitative study.

BACKGROUND: Approximately 14% of free-living adults aged ≥65 years are at risk of malnutrition. Malnutrition screen and treat interventions in primary care are few, show mixed results, and the advice given is not always accepted and followed. We need to better understand the experiences and contexts of older adults when aiming to develop interventions that are engaging, optimally persuasive and relevant. METHODS: Using the Person-based Approach, we carried out 23 semi-structured interviews with purposively selected adults ≥65 years with chronic health or social conditions associated with malnutrition risk. Thematic analysis informed the development of key principles to guide planned intervention development. RESULTS: We found that individuals' beliefs about an inevitable decline in appetite and eating in older age compound the many and varied physical and physiological barriers that they experience. Also, we found that expectations of decline in appetite and physical ability may encourage resignation, reduce self-efficacy to overcome barriers, and reduce motivation to address weight loss and/or recognise it as an issue that needs to be addressed. Fear of loss of independence may also reduce the likelihood of asking general practitioners for advice. CONCLUSIONS: The key findings identified include a sense of resignation, multiple different barriers to eating and a need for independence, each underpinned by the expectation of a decline in older adulthood. Interventions need to address misperceptions about the inevitability of decline, highlight how and why diet recommendations are somewhat different from recommendations for the general population, and suggest easy ways to increase food intake that address common barriers.

Factors associated with adherence to self-isolation and lockdown measures in the UK: a cross-sectional survey.

OBJECTIVES: To investigate factors associated with adherence to self-isolation and lockdown measures due to COVID-19 in the UK. STUDY DESIGN: Online cross-sectional survey. METHODS: Data were collected between 6th and 7th May 2020. A total of 2240 participants living in the UK aged 18 years or older were recruited from YouGov's online research panel. RESULTS: A total of 217 people (9.7%) reported that they or someone in their household had symptoms of COVID-19 (cough or high temperature/fever) in the last 7 days. Of these people, 75.1% had left the home in the last 24 h (defined as non-adherent). Men were more likely to be non-adherent, as were people who were less worried about COVID-19, and who perceived a smaller risk of catching COVID-19. Adherence was associated with having received help from someone outside your household. Results should be taken with caution as there was no evidence for associations when controlling for multiple analyses. Of people reporting no symptoms in the household, 24.5% had gone out shopping for non-essentials in the last week (defined as non-adherent). Factors associated with non-adherence and with a higher total number of outings in the last week included decreased perceived effectiveness of government 'lockdown' measures, decreased perceived severity of COVID-19 and decreased estimates of how many other people were following lockdown rules. Having received help was associated with better adherence. CONCLUSIONS: Adherence to self-isolation is poor. As we move into a new phase of contact tracing and self-isolation, it is essential that adherence is improved. Communications should aim to increase knowledge about actions to take when symptomatic or if you have been in contact with a possible COVID-19 case. They should also emphasise the risk of catching and spreading COVID-19 when out and about and the effectiveness of preventative measures. Using volunteer networks effectively to support people in isolation may promote adherence.

Intervention planning for Antibiotic Review Kit (ARK): a digital and behavioural intervention to safely review and reduce antibiotic prescriptions in acute and general medicine.

BACKGROUND: Hospital antimicrobial stewardship strategies, such as 'Start Smart, Then Focus' in the UK, balance the need for prompt, effective antibiotic treatment with the need to limit antibiotic overuse using 'review and revise'. However, only a minority of review decisions are to stop antibiotics. Research suggests that this is due to both behavioural and organizational factors. OBJECTIVES: To develop and optimize the Antibiotic Review Kit (ARK) intervention. ARK is a complex digital, organizational and behavioural intervention that supports implementation of 'review and revise' to help healthcare professionals safely stop unnecessary antibiotics. METHODS: A theory-, evidence- and person-based approach was used to develop and optimize ARK and its implementation. This was done through iterative stakeholder consultation and in-depth qualitative research with doctors, nurses and pharmacists in UK hospitals. Barriers to and facilitators of the intervention and its implementation, and ways to address them, were identified and then used to inform the intervention's development. RESULTS: A key barrier to stopping antibiotics was reportedly a lack of information about the original prescriber's rationale for and their degree of certainty about the need for antibiotics. An integral component of ARK was the development and optimization of a Decision Aid and its implementation to increase transparency around initial prescribing decisions. CONCLUSIONS: The key output of this research is a digital and behavioural intervention targeting important barriers to stopping antibiotics at review (see http://bsac-vle.com/ark-the-antibiotic-review-kit/ and http://antibioticreviewkit.org.uk/). ARK will be evaluated in a feasibility study and, if successful, a stepped-wedge cluster-randomized controlled trial at acute hospitals across the NHS.

Using an Analysis of Behavior Change to Inform Effective Digital Intervention Design: How Did the PRIMIT Website Change Hand Hygiene Behavior Across 8993 Users?

BACKGROUND: In designing digital interventions for healthcare, it is important to understand not just whether interventions work but also how and for whom-including whether individual intervention components have different effects, whether a certain usage threshold is required to change behavior in each intervention and whether usage differs across population subgroups. PURPOSE: We investigated these questions using data from a large trial of the digital PRimary care trial of a website based Infection control intervention to Modify Influenza-like illness and respiratory tract infection Transmission) (PRIMIT) intervention, which aimed to reduce respiratory tract infections (RTIs) by increasing hand hygiene behavior. METHOD: Baseline and follow-up questionnaires measured behaviors, intentions and attitudes in hand hygiene. In conjunction with objective measures of usage of the four PRIMIT sessions, we analysed these observational data to examine mechanisms of behavior change in 8993 intervention users. RESULTS: We found that the PRIMIT intervention changed behavior, intentions and attitudes, and this change was associated with reduced RTIs. The largest hand hygiene change occurred after the first session, with incrementally smaller changes after each subsequent session, suggesting that engagement with the core behavior change techniques included in the first session was necessary and sufficient for behavior change. The intervention was equally effective for men and women, older and younger people and was particularly effective for those with lower levels of education. CONCLUSIONS: Our well-powered analysis has implications for intervention development. We were able to determine a 'minimum threshold' of intervention engagement that is required for hand hygiene change, and we discuss the potential implications this (and other analyses of this type) may have for further intervention development. We also discuss the application of similar analyses to other interventions.

Managing fatigue after cancer treatment: development of RESTORE, a web-based resource to support self-management.

OBJECTIVE: The aim of this study is to co-create an evidence-based and theoretically informed web-based intervention (RESTORE) designed to enhance self-efficacy to live with cancer-related fatigue (CRF) following primary cancer treatment. METHODS: A nine-step process informed the development of the intervention: (1) review of empirical literature; (2) review of existing patient resources; (3) establish theoretical framework; (4) establish design team with expertise in web-based interventions, CRF and people affected by cancer; (5) develop prototype intervention; (6) user testing phase 1; (7) refinement of prototype; (8) user testing phase 2; and (9) develop final intervention. RESULTS: Key stakeholders made a critical contribution at every step of intervention development, and user testing, which involved an iterative process and resulted in the final intervention. The RESTORE intervention has five sessions; sessions 1 and 2 include an introduction to CRF and goal setting. Sessions 3-5 can be tailored to user preference and are designed to cover areas of life where CRF may have an impact: home and work life, personal relationships and emotional adjustment. CONCLUSIONS: It is feasible to systematically 'co-create' an evidence-based and theory-driven web-based self-management intervention to support cancer survivors living with the consequences of cancer and its treatment. This is the first account of the development of a web-based intervention to support self-efficacy to manage CRF. An exploratory trial to test the feasibility and acceptability of RESTORE is now warranted.

Enhancing the effectiveness of diabetes self-management education: the diabetes literacy project.

Patient empowerment through self-management education is central to improving the quality of diabetes care and preventing Type 2 Diabetes. Although national programs exist, there is no EU-wide strategy for diabetes self-management education, and patients with limited literacy face barriers to effective self-management. The Diabetes Literacy project, initiated with the support of the European Commission, aims to fill this gap. The project investigates the effectiveness of diabetes self-management education, targeting people with or at risk of Type 2 Diabetes in the 28 EU Member States, as part of a comprehensive EU-wide diabetes strategy. National diabetes strategies in the EU, US, Taiwan, and Israel are compared, and diabetes self-management programs inventorized. The costs of the diabetes care pathway are assessed on a per person basis at national level. A comparison is made of the (cost)-effectiveness of different methods for diabetes self-management support, and the moderating role of health literacy, organization of the health services, and implementation fidelity of education programs are considered. Web-based materials are developed and evaluated by randomized trials to evaluate if interactive internet delivery can enhance self-management support for people with lower levels of health literacy. The 3-year project started in December 2012. Several literature reviews have been produced and protocol development and research design are in the final stages. Primary and secondary data collection and analysis take place in 2014. The results will inform policy decisions on improving the prevention, treatment, and care for persons with diabetes across literacy levels.

Validation of the Falls Efficacy Scale and Falls Efficacy Scale International in geriatric patients with and without cognitive impairment: results of self-report and interview-based questionnaires.

BACKGROUND: Frail, old patients with and without cognitive impairment are at high risk of falls and associated medical and psychosocial issues. The lack of adequate, validated instruments has partly hindered research in this field. So far no questionnaire documenting fall-related self-efficacy/fear of falling has been validated for older persons with cognitive impairment or for different administration methods such as self-report or interview. OBJECTIVE: To validate the self-report and interview version of the Falls Efficacy Scale (FES) and the Falls Efficacy Scale International Version (FES-I) in frail geriatric patients with and without cognitive impairment. METHODS: 156 geriatric patients in geriatric rehabilitations wards with (n = 75) and without cognitive impairment (n = 81) were included in this study. Reports of fall-related self-efficacy were based on self-reported and interview-based questionnaires. Descriptive statistics, reliability estimates and validation results were computed for the total group and sub-samples with respect to cognitive status, for the 2 different questionnaires (FES/FES-I) and for the 2 administration methods. Test-retest reliability was tested in a subsample of 62 patients. RESULTS: Internal reliability and test-retest reliability were good to excellent in both the FES and FES-I, with the FES-I showing better internal reliability and the FES better test-retest reliability with respect to cognitively impaired persons. The group of cognitively impaired persons tended to show lower test-retest reliability and mean fall-related self-efficacy and had significantly lower completion rates in self-administered questionnaires. As indicated by significant differences in parameters closely related to falls, such as vertigo, functional performances, fear of falling and history of falls, both the FES and the FES-I showed good construct validity. Effect sizes computed for the above-mentioned groups for fall-related parameters confirmed the results of construct validation. CONCLUSION: Both the FES as well as the FES-I showed good to excellent measurement properties in persons with and without moderate cognitive impairment. In frail older persons, especially in persons with cognitive impairment, an interview-based administration method is recommended.

Socio-demographic factors predict the likelihood of not returning home after hospital admission following a fall.

BACKGROUND: Falls in older people result in a substantial use of resources in the NHS and care homes. One way to reduce the burden would be to identify the factors associated with the likelihood of being discharged to a care home rather than being discharged home after fall-related hospitalization. We investigate the associations between discharge destination after fall-related hospital admission with ecological factors (area deprivation, ethnicity and rurality) and individual level factors (age, gender and co-morbidities). METHODS: We extracted data for patients aged over 50 admitted from their 'usual residence' with a fall-related diagnosis from the Hospital Episode Statistics (HES) database. RESULTS: Increasing age, people with severe co-morbidities and people who live in less deprived, predominantly white or rural areas, were more likely to be discharged to a different residence (all P-values < 0.001). We estimated that 88.3% of people from an area classified as most deprived, urban and >5% Asian would return home, compared with 78.0% from least deprived, village/isolated and all white area. CONCLUSION: Further research is required to examine whether these patterns reflect appropriate care or alternatively that some sub-groups of society have less access to care homes than others. These factors may have public health implications for the equitable allocation of budgets for the provision of care for elderly patients discharged from hospital after a fall.

Feasibility and acceptability of a brief routine weight management intervention for postnatal women embedded within the national child immunisation programme in primary care: randomised controlled cluster feasibility trial.

BACKGROUND: The prevalence of obesity in women continues to rise and pregnancy is a high-risk time for excessive weight gain. The period after childbirth represents an opportunity to offer women support to manage their weight. The primary aim here was to investigate the acceptability and feasibility of delivering a self-management intervention to postnatal women to support weight loss, embedded within the national child immunisation programme. METHODS: The research involved a randomised controlled cluster feasibility trial. Data were collected at baseline and 3 months later. Twenty-eight postnatal women living with overweight or obesity were recruited via Birmingham Women Hospital or general practices. Babies are routinely immunised at 2, 3 and 4 months of age; the intervention was embedded within these appointments. The intervention involved brief motivation/support by practice nurses to encourage participants to make healthier lifestyle choices through self-monitoring of weight and signposting to an online weight management programme, when they attended their practice to have their child immunised. The role of the nurse was to provide external accountability for weight loss. Participants were asked to weigh themselves weekly and record this on a record card or using the online programme. The weight goal was for participants to lose 0.5 to 1 kg per week. Usual care received a healthy lifestyle leaflet. The primary outcome was the feasibility of a phase III trial to test the subsequent effectiveness of the intervention, as assessed against three stop-go traffic light criteria (recruitment, adherence to regular self-weighing and registration with an online weight management programme). RESULTS: The traffic light stop-go criteria results were red for recruitment (28/80, 35% of target), amber for registration with the online weight loss programme (9/16, 56%) and green for adherence to weekly self-weighing (10/16, 63%). Nurses delivered the intervention with high fidelity. DISCUSSION: Whilst participants and nurses followed the trial protocol well and adherence to self-weighing was acceptable, recruitment was challenging and there is scope to improve engagement with the online weight management programme component of the intervention. TRIAL REGISTRATION: ISRCTN 12209332 . Registration date is 04/12/18.

Adaptation and implementation of the ARK (Antibiotic Review Kit) intervention to safely and substantially reduce antibiotic use in hospitals: a feasibility study.

BACKGROUND: Antimicrobial stewardship initiatives in secondary care depend on clinicians undertaking antibiotic prescription reviews but decisions to limit antibiotic treatment at review are complex. AIM: To assess the feasibility and acceptability of implementing ARK (Antibiotic Review Kit), a behaviour change intervention made up of four components (brief online tool, prescribing decision aid, regular data collection and feedback process, and patient leaflet) to support stopping antibiotic treatment when it is safe to do so among hospitalized patients; before definitive evaluation through a stepped-wedge cluster-randomized controlled trial. METHODS: Acceptability of the different intervention elements was assessed for a period of 12 weeks by uptake of the online tool, adoption of the decision aid into prescribing practice, and rates of decisions to stop antibiotics at review (assessed through repeated point-prevalence surveys). Patient perceptions of the information leaflet were assessed through a brief questionnaire. FINDINGS: All elements of the intervention were successfully introduced into practice. A total of 132 staff encompassing a broad range of prescribers and non-prescribers completed the online tool (19.4 per 100 acute beds), including 97% (32/33) of the pre-specified essential clinical staff. Among 588 prescription charts evaluated in seven point-prevalence surveys over the 12-week implementation period, 82% overall (76-90% at each survey) used the decision aid. The median antibiotic stop rate post implementation was 36% (range: 29-40% at each survey) compared with 9% pre implementation (P < 0.001). CONCLUSION: ARK provides a feasible and acceptable mechanism to support stopping antibiotics safely at post-prescription reviews in an acute hospital setting.

Predicting people with stroke at risk of falls.

BACKGROUND: falls are common following a stroke, but knowledge about predicting future fallers is lacking. OBJECTIVE: to identify, at discharge from hospital, those who are most at risk of repeated falls. METHODS: consecutively hospitalised people with stroke (independently mobile prior to stroke and with intact gross cognitive function) were recruited. Subjects completed a battery of tests (balance, function, mood and attention) within 2 weeks of leaving hospital and at 12 months post hospital discharge. RESULTS: 122 participants (mean age 70.2 years) were recruited. Fall status at 12 months was available for 115 participants and of those, 63 [55%; 95% confidence interval (CI) 46-64] experienced one or more falls, 48 (42%; 95% CI 33-51) experienced repeated falls, and 62 (54%) experienced near-falls. All variables available at discharge were screened as potential predictors of falling. Six variables emerged [near-falling in hospital, Rivermead leg and trunk score, Rivermead upper limb score, Berg Balance score, mean functional reach, and the Nottingham extended activities of daily living (NEADL) score]. A score of near-falls in hospital and upper limb function was the best predictor with 70% specificity and 60% sensitivity. CONCLUSION: participants who were unstable (near-falls) in hospital with poor upper limb function (unable to save themselves) were most at risk of falls.

Interference between balance, gait and cognitive task performance among people with stroke living in the community.

PURPOSE: To explore differences in cognitive-motor interference between people with stroke and controls when performing functional tasks and to compare dual task performance of stroke fallers and non-fallers. METHOD: Thirty-six people with stroke (mean age 66.5, SD 11.8, mean time since onset 16 months, range 7 - 56) and 24 controls (mean age 62.3, SD 11.61) performed balance and gait tasks in isolation and in conjunction with a cognitive task (remembering a seven item-shopping list). Three-dimensional movement analysis was used to assess anterior posterior (AP) and lateral (ML) sway; 5 m walk time, stride length and velocity. RESULTS: In the single task condition, people with stroke had greater AP sway, reduced velocity and stride length and a longer 5 m walk time than controls (p < 0.01). In the dual task condition, sway reduced and gait slowed in both groups (p < 0.01 for AP sway, stride length, velocity, walk time); only the increase in walk time was greater in people with stroke than in the controls (F = 4.2, p = 0.046). Cognitive performance was maintained during the balance trials but deteriorated during the dual task gait trials in people with stroke (p = 0.017). Similar trends were noted for fallers and non-fallers with stroke: Only group effects for stride length and velocity reached significance (p < 0.05) and only the reduction in stride length was significantly greater among fallers than non-fallers (F = 12.3, p = 0.001). CONCLUSIONS: People with stroke and controls employed similar strategies during the simultaneous performance of simple functional and silent cognitive tasks and maintained postural stability. Increased walk time and decreased cognitive recall were greater for people with stroke and reduced stride length distinguished fallers from non-fallers.

Parents' and carers' views about emollients for childhood eczema: qualitative interview study.

OBJECTIVE: Leave-on emollients form the mainstay of eczema treatment, but adherence is poor. We aimed to explore parents'/carers' views on effectiveness and acceptability of leave-on emollients for childhood eczema through secondary analysis of data from 2 qualitative data sets. SETTING: Study 1 recruited through mail-out from 6 general practices in southern England. Study 2 recruited from a feasibility trial of an intervention to support eczema self-care in 31 practices in the same area. PARTICIPANTS: Study 1 included 28 interviews with carers of children aged ≤5 years with eczema. Study 2 included 26 interviews with carers of children aged ≤5 years with eczema. METHODS: Interviews followed semistructured guides: study 1 explored carers' understandings around eczema treatments in order to develop a web-based self-care support intervention; study 2 explored carers' understandings of eczema and eczema treatments after using the intervention. Interviews were carried out face to face or by telephone, audio-recorded and transcribed. Secondary analysis of data from both studies focused on views and experiences of emollient use. Data were analysed using an inductive thematic approach facilitated by NVivo V.10 software. RESULTS: In study 1, most participants felt emollients improved eczema but held mixed views about long-term use to prevent flare-ups. In study 2, where carers had used the web-based intervention, all participants held positive views about long-term emollient use. In both studies, participants expressed a range of preferences about emollient 'thickness'; some felt that 'thick' emollients (ointments) were most effective, while others found these difficult to use. Carers described a process of 'trial and error', trying emollients suggested by professionals, friends and family, or bought over-the-counter. Carers expressed a need for understanding differences between products and their effective use. CONCLUSIONS: Providing a rationale for long-term emollient use and choice of emollients could help improve adherence and help families gain more rapid control of eczema.

Findings from a pilot Randomised trial of an Asthma Internet Self-management Intervention (RAISIN).

OBJECTIVE: To evaluate the feasibility of a phase 3 randomised controlled trial (RCT) of a website (Living Well with Asthma) to support self-management. DESIGN AND SETTING: Phase 2, parallel group, RCT, participants recruited from 20 general practices across Glasgow, UK. Randomisation through automated voice response, after baseline data collection, to website access for minimum 12 weeks or usual care. PARTICIPANTS: Adults (age≥16 years) with physician diagnosed, symptomatic asthma (Asthma Control Questionnaire (ACQ) score ≥1). People with unstable asthma or other lung disease were excluded. INTERVENTION: 'Living Well with Asthma' is a desktop/laptop compatible interactive website designed with input from asthma/ behaviour change specialists, and adults with asthma. It aims to support optimal medication management, promote use of action plans, encourage attendance at asthma reviews and increase physical activity. OUTCOME MEASURES: Primary outcomes were recruitment/retention, website use, ACQ and mini-Asthma Quality of Life Questionnaire (AQLQ). Secondary outcomes included patient activation, prescribing, adherence, spirometry, lung inflammation and health service contacts after 12 weeks. Blinding postrandomisation was not possible. RESULTS: Recruitment target met. 51 participants randomised (25 intervention group). Age range 16-78 years; 75% female; 28% from most deprived quintile. 45/51 (88%; 20 intervention group) followed up. 19 (76% of the intervention group) used the website, for a mean of 18 min (range 0-49). 17 went beyond the 2 'core' modules. Median number of logins was 1 (IQR 1-2, range 0-7). No significant difference in the prespecified primary efficacy measures of ACQ scores (-0.36; 95% CI -0.96 to 0.23; p=0.225), and mini-AQLQ scores (0.38; -0.13 to 0.89; p=0.136). No adverse events. CONCLUSIONS: Recruitment and retention confirmed feasibility; trends to improved outcomes suggest use of Living Well with Asthma may improve self-management in adults with asthma and merits further development followed by investigation in a phase 3 trial. TRIAL REGISTRATION NUMBER: ISRCTN78556552; Results.

Developing a measure of treatment beliefs: the complementary and alternative medicine beliefs inventory.

OBJECTIVES: The study aimed to develop a comprehensive generic measure of treatment beliefs, the Complementary and Alternative Medicine Beliefs Inventory (CAMBI), and to identify distinct dimensions of CAM-related beliefs. METHODS: The CAMBI and other measures were presented and advertised online. RESULTS: 328 completed questionnaires were received. Factor analysis indicated three dimensions of beliefs could be identified. Subscales of the CAMBI were developed measuring beliefs in natural treatment, participation in treatment and holistic health. The subscales all had satisfactory reliability and were significantly correlated with CAM use (Spearman's rho=.18, .47 and .22 for natural treatments, holistic health and participation in treatment, respectively). CONCLUSIONS: The CAMBI measures three distinct dimensions of treatment beliefs, all of which are related to CAM use.

Visually and posturally mediated tilt illusion in Parkinson's disease and in labyrinthine defective subjects.

We tested 24 normal subjects, 24 patients with idiopathic Parkinson's disease (PD), and eight patients with bilateral absence of vestibular function (labyrinthine defective [LD] subjects) in their ability to set a straight line to the perceived gravitational vertical (visual vertical). Measurements were taken in static conditions, sitting upright, and lying down on the right side, and during visual background motion at constant angular velocities around the line of sight (roll-motion) in both sitting upright and sideways position. Aims of the study were to determine if the reported increased "visual dependence" in PD was present in a psychophysical task that is independent of motor performance, and to examine the interaction between visual motion and proprioceptive cues in the perception of verticality, in the absence of vestibular function. LD patients showed abnormally large deviations of the visual vertical induced both by lateral body tilt and by visual roll-motion. This suggests that vestibular cues play a significant part in counterbalancing visually and proprioceptive mediated biases on the perception of verticality. In contrast, PD patients were normal in all these tasks indicating that visual dependence in PD is not present at an afferent/perceptual level.

Attentional demands of perception of passive self-motion in darkness.

The purpose of this study was to determine whether significant attentional resources are required to accurately monitor changes in bodily orientation, using vestibular information. This question was addressed firstly using a dual-task paradigm in which orientation perception tasks and a speeded auditory tone discrimination task were carried out either singly or in combination. For the active orientation perception task, subjects were seated in darkness on a motorised chair which could be rotated about an earth-vertical axis. Following passive angular displacements, subjects were required to return the chair to their perceived starting position, using a joy-stick which controlled chair motion. For the speeded auditory task, subjects pushed a hand-held button as fast as possible when a tone was presented over headphones. When the two tasks were combined, reaction times on the auditory task increased. Reaction time also increased when subjects were simply asked to fixate during rotation. A second experiment demonstrated that if attention was occupied by performance of a demanding mental arithmetic task during the passive rotation, accuracy of subsequently repositioning the chair to the origin declined, implying that change in orientation had been less accurately registered when performing the concurrent mental task. In combination, these findings indicate that a small but significant degree of attention or cognitive effort is necessary to monitor accurately the direction and amplitude of a brief angular rotation, and to suppress vestibulo-ocular reflex eye movement.
