First validation study of the living with long term conditions scale (LwLTCs) among English-speaking population living with Parkinson's disease.

INTRODUCTION: Parkinson's disease is the second most prevalent neurodegenerative disease, affecting 10 million people worldwide. Health and social care professionals need to have personalised tools to evaluate the process of living with Parkinson's disease and consequently, plan individualised and targeted interventions. Recently, the English version of the Living with Long term conditions (LwLTCs) scale has been developed filling an important gap related to person-centred tools to evaluate the process of living with long term conditions among English-speaking population. However, no validation studies for testing its psychometric properties have been conducted. AIM: To analyse the psychometric properties of the LwLTCs scale in a wide English-speaking population living with Parkinson's disease. METHODS: Validation study, with an observational and cross-sectional design. The sample was composed of individuals living with Parkinson's disease from non-NHS services in the community. Psychometric properties including feasibility and acceptability, internal consistency, reproducibility, and construct, internal and known-groups validity were tested. RESULTS: A total sample of 241 people living with Parkinson's disease were included. 6 individuals did not complete 1 or 2 items on the scale. Ordinal alpha was 0.89 for the total scale. The intraclass correlation coefficient for the total scale was 0.88. The LwLTCs scale is strongly correlated with scales measuring satisfaction with life (rs=0.67), quality of life (rs=0.54), and moderately correlated with social support (rs=0.45). Statistically significant difference just for therapy and co-morbidity, yet no for gender, employment situation, or lifestyle changes. CONCLUSIONS: The LwLTCs scale is a valid scale to evaluate how the person is living with Parkinson's disease. Future validation studies to prove the repeatability of the total scale and particularly, domains 3-Self-management, and 4-Integration and internal consistency will be needed. Developing further studies on the English version of the LwLTC in people with other long term conditions is also proposed.

The clinical and cost effectiveness of splints for thumb base osteoarthritis: a randomized controlled clinical trial.

OBJECTIVES: To investigate the clinical effectiveness, efficacy and cost effectiveness of splints (orthoses) in people with symptomatic basal thumb joint OA (BTOA). METHODS: A pragmatic, multicentre parallel group randomized controlled trial at 17 National Health Service (NHS) hospital departments recruited adults with symptomatic BTOA and at least moderate hand pain and dysfunction. We randomized participants (1:1:1) using a computer-based minimization system to one of three treatment groups: a therapist supported self-management programme (SSM), a therapist supported self-management programme plus a verum thumb splint (SSM+S), or a therapist supported self-management programme plus a placebo thumb splint (SSM+PS). Participants were blinded to group allocation, received 90 min therapy over 8 weeks and were followed up for 12 weeks from baseline. Australian/Canadian (AUSCAN) hand pain at 8 weeks was the primary outcome, using intention to treat analysis. We calculated costs of treatment. RESULTS: We randomized 349 participants to SSM (n = 116), SSM+S (n = 116) or SSM+PS (n = 117) and 292 (84%) provided AUSCAN Osteoarthritis Hand Index hand pain scores at the primary end point (8 weeks). All groups improved, with no mean treatment difference between groups: SSM+S vs SSM -0.5 (95% CI: -1.4, 0.4), P = 0.255; SSM+PS vs SSM -0.1 (95% CI: -1.0, 0.8), P = 0.829; and SSM+S vs SSM+PS -0.4 (95% CI: -1.4, 0.5), P = 0.378. The average 12-week costs were: SSM £586; SSM+S £738; and SSM+PS £685. CONCLUSION: There was no additional benefit of adding a thumb splint to a high-quality evidence-based, supported self-management programme for thumb OA delivered by therapists.

Problems faced by people living at home with dementia and incontinence: causes, consequences and potential solutions.

BACKGROUND: many people living at home with dementia (PLWD) also have poorly managed toilet-use or incontinence problems with damaging consequences for both people with dementia, unpaid carers and healthcare professionals (HCPs). Currently, there are no theoretically or empirically based interventions to help. The underlying causes and subsequent consequences of these problems need to be fully understood in order to support the development of interventions that have the potential to decrease the impact of these problems on people's lives. AIM: to establish the range of causes, consequences and potential solutions of toilet-use and incontinence problems for PLWD and their carers. METHOD: a qualitative design was used. Semi-structured interviews were undertaken with PLWD, carers and HCPs (continence or dementia nurses). PLWD and carers were recruited via www.joindementiaresearch.nihr.ac.uk and via dementia/carer groups. Nurses were recruited via their employers. Interviews were digitally recorded and transcribed verbatim. Framework analysis was used to interpret the data to address the goal of the research. RESULTS: in total, 45 people (26 unpaid carers, 2 people with dementia, 9 continence and 8 dementia HCPs) took part. The causes of toilet-use and incontinence problems were reported to be multi-faceted and complex including those related to dementia (e.g. lack of insight into toileting needs or how to use the toilet), those which are physical (e.g. existing bladder or bowel issues or poor mobility), psychosocial (e.g. inability to ask for help for incontinence) or societal (e.g. fear of stigma), or related to care systems (e.g. lack of expert knowledge) or products (e.g. poor fit or confusing for users). Consequences included harms to physical and mental health, social isolation, increased carer workload and care system resource implications. CONCLUSION: this study provides the first detailed characterisation of the causes and consequences of and potential solutions for incontinence problems for PLWD at home and their carers. Multifaceted and complex problems were identified, layering dementia, physical, psychosocial, societal and care system factors and highlighting contextual variation. This new knowledge provides the essential basis for the (now underway) development of urgently needed practical and implementable interventions for this underserved population.

Psychometric properties of the living with long term conditions scale in an English-speaking population living with long term conditions in the UK.

OBJECTIVE: To present the psychometric properties of the living with long-term condition (LwLTCs) scale in an English-speaking population of people with different LTCs. DESIGN: An observational and cross-sectional study, with retest was conducted. Psychometric properties including feasibility, internal consistency, confirmatory factor analysis, reproducibility and content validity were tested. SETTING: The study took place across the UK via primary care surgeries and voluntary organisations, between December 2021 and June 2022. PARTICIPANTS: The study included 577 patients living with different LTCs, as chronic obstructive pulmonary disease, arthritis, chronic heart failure, Parkinson's disease, chronic kidney disease and type 2 diabetes mellitus. Inclusion criteria included: (a) having been diagnosed with one or more of the conditions; (b) being able to read, understand and answer written questionnaires; (c) being fluent in English and (d) being able to provide written informed consent. Patients were involved in the design and pilot study of the scale. RESULTS: A total sample of 577 people with an age range of 37-97 years (98±9.65) were recruited. Internal consistency of the total 26-item LwLTCs scale score was excellent (ordinal alpha=0.90) but confirmatory factor analysis showed better fit indices (Normed Fit Index=0.96; standardised root mean square residual=0.051; Goodness of Fit Index=0.98) for a 20-item LwLTCs scale. CONCLUSIONS: A shorter version of the LwLTCs scale, with just 20 items and with excellent psychometric properties, is recommended. Having a short scale is key when considering the implementation of the scale in clinical practice to develop person-centred pathways and more comprehensive care plans.

Living with Long term condition Scale: A pilot validation study of a new person centred tool in the UK.

AIM: To cross-culturally adapt and determine the preliminary psychometric properties of the English version of the LwLTC Scale in people living with long-term conditions in the UK. DESIGN: Cross-cultural adaptation and cross-sectional study. METHODS: Forty-nine patients with five long-term conditions were included in the pilot study. Patients completed the English version of the LwLTC Scale and a bespoke questionnaire related to the scale. Feasibility/acceptability, internal consistency and construct validity were analysed. RESULTS: 59.2% of participants were female, with an average age of 65.9 (SD = 12.30). Cronbach's alpha coefficient ranged between 0.50 and 0.84. Content validity showed that the English version of the LwLTC Scale was useful even negative items were identified. CONCLUSION: These preliminary psychometric properties are satisfactory and promising. Further psychometric analyses are needed to verify them in a larger and more representative sample size during the main validation study, which is now in process.

The Osteoarthritis Thumb Therapy (OTTER) II Trial: a study protocol for a three-arm multi-centre randomised placebo controlled trial of the clinical effectiveness and efficacy and cost-effectiveness of splints for symptomatic thumb base osteoarthritis.

INTRODUCTION: The economic cost of osteoarthritis (OA) is high. At least 4.4 million people have hand OA in the UK. Symptomatic thumb base OA affects 20% of people over 55 years, causing more pain, work and functional disability than OA elsewhere in the hand. Most evidence-based guidelines recommend splinting for hand OA. Splints that support or immobilise the thumb base are routinely used despite there being limited evidence on their effectiveness. The potential effects of placebo interventions in OA are acknowledged, but few studies investigate the clinical efficacy of rehabilitation interventions nor the impact of any placebo effects associated with splints. METHODS AND ANALYSIS: Participants aged 30 years and over with symptomatic thumb base OA will be recruited into the trial from secondary care occupational therapy and physiotherapy centres. Following informed consent, participants will complete a baseline questionnaire and then be randomised into one of three treatment arms: a self-management programme, a self-management programme plus a verum thumb splint or a self-management programme plus a placebo thumb splint. The primary outcome is the Australian Canadian Osteoarthritis Hand Index (AUSCAN) hand pain scale. The study endpoint is 8 weeks after baseline. Baseline assessments will be carried out prior to randomisation and outcomes collected at 4, 8 and 12 weeks. Cost-effectiveness analysis will be conducted and individual qualitative interviews conducted with up to 40 participants after 8 weeks to explore perceptions and outcome expectations of verum and placebo splints and exercise. ETHICS AND DISSEMINATION: South Central-Oxford C Research Ethics Committee approved this study (16/SC/0188). The findings will be disseminated to health professional conferences, journals and lay publications for patient organisations. The research will contribute to improving the management of thumb base OA and help clinicians and patients make informed decisions about the value of different interventions.
