Using telehealth in motor neuron disease to increase access to specialist multidisciplinary care: a UK-based pilot and feasibility study.

OBJECTIVES: Care of patients with motor neuron disease (MND) in a specialist, multidisciplinary clinic is associated with improved survival, but access is not universal. We wanted to pilot and establish the feasibility of a definitive trial of a novel telehealth system (Telehealth in Motor neuron disease, TiM) in patients with MND. DESIGN: An 18-month, single-centre, mixed-methods, randomised, controlled pilot and feasibility study. INTERVENTION: TiM telehealth plus usual care versus usual care. SETTING: A specialist MND care centre in the UK. PARTICIPANTS: Patients with MND and their primary informal carers. PRIMARY AND SECONDARY OUTCOME MEASURES: Recruitment, retention and data collection rates, clinical outcomes including participant quality of life and anxiety and depression. RESULTS: Recruitment achieved the target of 40 patients and 37 carers. Participant characteristics reflected those attending the specialist clinic and included those with severe disability and those with limited experience of technology. Retention and data collection was good. Eighty per cent of patients and 82% of carer participants reported outcome measures were completed at 6 months. Using a longitudinal analysis with repeated measures of quality of life (QoL), a sample size of 131 per arm is recommended in a definitive trial. The methods and intervention were acceptable to participants who were highly motivated to participate to research. The low burden of participation and accessibility of the intervention meant barriers to participation were minimal. However, the study highlighted difficulties assessing the associated costs of the intervention, the challenge of recruitment in such a rare disease and the difficulties of producing rigorous evidence of impact in such a complex intervention. CONCLUSION: A definitive trial of TiM is feasible but challenging. The complexity of the intervention and heterogeneity of the patient population means that a randomised controlled trial may not be the best way to evaluate the further development and implementation of the TiM. TRIAL REGISTRATION NUMBER: ISRCTN26675465.

The TiM system: developing a novel telehealth service to improve access to specialist care in motor neurone disease using user-centered design.

OBJECTIVES: Attendance at a specialist multidisciplinary motor neurone disease (MND) clinic is associated with improved survival and may also improve quality of life and reduce hospital admissions. However, patients struggle to travel to clinic and may experience difficulties between clinic visits that may not be addressed in a timely manner. We wanted to explore how we could improve access to specialist MND care. METHODS: We adopted an iterative, user-centered co-design approach, collaborating with those with experience of providing and receiving MND care including patients, carers, clinicians, and technology developers. We explored the unmet needs of those living with MND, how they might be met through service redesign and through the use of digital technologies. We developed a new digital solution and performed initial testing with potential users including clinicians, patients, and carers. RESULTS: We used these findings to develop a telehealth system (TiM) using an Android app into which patients and carers answer a series of questions about their condition on a weekly basis. The questions aim to capture all the physical, emotional, and social difficulties associated with MND. This information is immediately uploaded to the internet for review by the MND team. The data undergoes analysis in order to alert clinicians to any changes in a patient or carer's condition. CONCLUSIONS: We describe the benefits of developing a novel digitally enabled service underpinned by participatory design. Future trials must evaluate the feasibility and acceptability of the TiM system within a clinical environment.

DiPALS: Diaphragm Pacing in patients with Amyotrophic Lateral Sclerosis - a randomised controlled trial.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease resulting in death, usually from respiratory failure, within 2-3 years of symptom onset. Non-invasive ventilation (NIV) is a treatment that when given to patients in respiratory failure leads to improved survival and quality of life. Diaphragm pacing (DP), using the NeuRx/4(®) diaphragm pacing system (DPS)™ (Synapse Biomedical, Oberlin, OH, USA), is a new technique that may offer additional or alternative benefits to patients with ALS who are in respiratory failure. OBJECTIVE: The Diaphragm Pacing in patients with Amyotrophic Lateral Sclerosis (DiPALS) trial evaluated the effect of DP on survival over the study duration in patients with ALS with respiratory failure. DESIGN: The DiPALS trial was a multicentre, parallel-group, open-label, randomised controlled trial incorporating health economic analyses and a qualitative longitudinal substudy. PARTICIPANTS: Eligible participants had a diagnosis of ALS (ALS laboratory-supported probable, clinically probable or clinically definite according to the World Federation of Neurology revised El Escorial criteria), had been stabilised on riluzole for 30 days, were aged ≥ 18 years and were in respiratory failure. We planned to recruit 108 patients from seven UK-based specialist ALS or respiratory centres. Allocation was performed using 1 : 1 non-deterministic minimisation. INTERVENTIONS: Participants were randomised to either standard care (NIV alone) or standard care (NIV) plus DP using the NeuRX/4 DPS. MAIN OUTCOME MEASURES: The primary outcome was overall survival, defined as the time from randomisation to death from any cause. Secondary outcomes were patient quality of life [assessed by European Quality of Life-5 Dimensions, three levels (EQ-5D-3L), Short Form questionnaire-36 items and Sleep Apnoea Quality of Life Index questionnaire]; carer quality of life (EQ-5D-3L and Caregiver Burden Inventory); cost-utility analysis and health-care resource use; tolerability and adverse events. Acceptability and attitudes to DP were assessed in a qualitative substudy. RESULTS: In total, 74 participants were randomised into the trial and analysed, 37 participants to NIV plus pacing and 37 to standard care, before the Data Monitoring and Ethics Committee advised initial suspension of recruitment (December 2013) and subsequent discontinuation of pacing (on safety grounds) in all patients (June 2014). Follow-up assessments continued until the planned end of the study in December 2014. The median survival (interquartile range) was 22.5 months (lower quartile 11.8 months; upper quartile not reached) in the NIV arm and 11.0 months (6.7 to 17.0 months) in the NIV plus pacing arm, with an adjusted hazard ratio of 2.27 (95% confidence interval 1.22 to 4.25; p = 0.01). CONCLUSIONS: Diaphragmatic pacing should not be used as a routine treatment for patients with ALS in respiratory failure. FUTURE WORK: It may be that certain population subgroups benefit from DP. We are unable to explain the mechanism behind the excess mortality in the pacing arm, something the small trial size cannot help address. Future research should investigate the mechanism by which harm or benefit occurs further. TRIAL REGISTRATION: Current Controlled Trials ISRCTN53817913.

Using technology to improve access to specialist care in amyotrophic lateral sclerosis: A systematic review.

Our objective was to review the evidence for using technology to improve access to specialist care for patients with amyotrophic lateral sclerosis (ALS) and their carers. Medline, Google Scholar and the Cochrane library were searched for articles describing technology that enabled clinical care of patients with ALS or their carers where the patient/carer and clinician were not in the same location. Two applications were identified: telemedicine to facilitate video conferencing as an alternative to outpatient consultations and telehealth monitoring for patients with respiratory failure. One randomized controlled trial using telehealth in patients with respiratory failure including 22 patients with ALS was identified. While rates of hospitalization were reduced, overall mortality was unchanged and there were too few patients with ALS in the study to detect significant benefit. In conclusion, there is limited evidence to support the use of telemedicine or telehealth in the care of patients with ALS. Future research needs to develop an understanding of the key beneficial aspects of the traditional specialist ALS service and how these factors could be delivered using technology. Successful evaluation and implementation of technologies to facilitate access to specialist care will only be possible if all the relevant impacts of an intervention are understood and measured.

The impact of gastrostomy in motor neurone disease: challenges and benefits from a patient and carer perspective.

OBJECTIVES: This study explores the experience of gastrostomy insertion from the perspective of the patients and their informal carers. Gastrostomy feeding is commonly used to support motor neurone disease (MND) patients with dysphagia. However, there is lack of information describing patient and carer experiences following gastrostomy insertion. The effect of gastrostomy on quality of life for these patients and their family is currently not well understood. METHODS: Retrospective qualitative exploration using semistructured interviews with patients and their informal carers to elicit in-depth descriptions of their experiences and views following gastrostomy. RESULTS: 27 patients consented to the study; of these, 23 underwent a successful gastrostomy. 10 patients and 8 carers were interviewed, approximately 3 months following a successful gastrostomy. Participants described clinical complications, practical issues, time restrictions imposed by strict feeding regimens and psychological issues, which adversely impacted on quality of life. However, the establishment of a safe alternative route for feeding and medication, and the reduced worry over difficult meals and weight loss, were described by all as outweighing these negative impacts. Participants also described having received education/training on gastrostomy feeding both in hospital and in the community, which helped them to cope during the transition from oral to gastrostomy feeding. CONCLUSIONS: This study highlights the challenges and benefits of gastrostomy as well as the importance of education and information provision. Emphasis should be given to education before and after insertion along with support and care in the community. While the significant impact of gastrostomy on patients and carers should not be underestimated, the potential benefits were described as outweighing these concerns.

Quality of life in children and adolescents with Osteogenesis Imperfecta: a qualitative interview based study.

BACKGROUND: Osteogenesis Imperfecta (OI) is a disease with varying severity affecting physical, social and emotional well-being of the child and their family. There is no existing evidence on how the OI population regard their quality of life (QoL). The main aim of this study was to determine how OI impacts on the quality of life and well-being of children and their family. It is the first stage of a larger project to develop a disease specific quality of life measure for children with OI. METHODS: Purposive sampling was used to cover the diversity of the OI population. Twenty-five qualitative interviews were undertaken with children (n = 10), parents (n = 10) and health professionals (n = 5). Interviews were digitally recorded and transcribed verbatim. Significant themes were identified, extracted and organised, undergoing framework analysis. RESULTS: Six main themes were identified; being safe and careful, reduced function, pain, fear, isolation, independence. There was a large amount of agreement between the three groups of interviewees, although discrepancies did occur between parents and children, with regard to the themes independence and fear. CONCLUSIONS: This data presents the first step in developing items for a disease specific QoL measure for children with OI. Several of the themes uncovered showed similarity to other QoL measures, but the addition of being safe and careful, particularly in relation to fractures, demonstrated the need for a disease specific measure for children with OI.

Factors influencing decision-making in relation to timing of gastrostomy insertion in patients with motor neurone disease.

OBJECTIVES: This study aimed to explore the decision-making process leading up to gastrostomy insertion from the perspective of the patients and their informal carers. Gastrostomy feeding is commonly used to support motor neurone disease patients with dysphagia. However, there is no robust evidence to suggest the optimal timing for gastrostomy insertion. METHODS: Retrospective qualitative exploration using semistructured interviews with paired patients and carers in order to elicit their perceptions in relation to gastrostomy timing. RESULTS: 27 patients consented to the study; of these, 23 underwent a successful gastrostomy. Approximately 3 months following a successful gastrostomy, 10 patients and 8 carers were interviewed. Decision-making in relation to the timing of gastrostomy was described as being a difficult process with individual variations and wishes. A range of factors acted as triggers for taking the decision to proceed with gastrostomy such as prolonged, tiring and effortful meals; the task of food preparation; choking and aspiration; and weight loss. Factors such as the reluctance to give up oral feeding, not realising the potential benefits and negative perceptions of gastrostomy influenced a decision to delay the procedure. A tendency for late insertion was identified despite the opposite advice by health professionals. CONCLUSIONS: The advice for early insertion does not outweigh the personal perceptions and psychosocial factors for patients and their carers. Understanding the factors which influence decision-making on an individual basis is important for information and care provision by healthcare professionals in aiding patients, and their carers, to make informed decisions in relation to gastrostomy timing.

The impact on the family carer of motor neurone disease and intervention with noninvasive ventilation.

BACKGROUND: The diagnosis of motor neurone disease (MND) has a profound effect on the functioning and well-being of both the patient and their family, with studies describing an increase in carer burden and depression as the disease progresses. AIM: This study aimed to assess whether patient use of noninvasive ventilation (NIV) impacted on their family carer, and to explore other sources of carer burden. DESIGN: The study used qualitative interviews and scaled measures of carer health and well-being completed at three monthly intervals until patient end of life. PARTICIPANTS: Sixteen family carers were followed up over a period ranging from one month to two years. RESULTS: NIV was perceived as having little impact on carer burden. The data however highlighted a range of sources of other burdens relating to the physical strain of caring. The Medical Outcomes Study Short Form (SF-36 Health Survey) Physical Component Summary (PCS) scores were considerably below that of the Mental Component Summary (MCS) score at baseline and at all following time points. Carers described the physical effort associated with patient care and role change; the challenge inherent in having time away; and problems relating to the timing of equipment and service delivery. CONCLUSIONS: NIV can be recommended to patients without concerns regarding increasing carer burden. The predominant source of burden described related to the physical impact of caring for a patient with MND. Services face challenges if this physical burden is to be reduced by providing equipment at an optimal time and successfully coordinating their input.

The use of non-invasive ventilation at end of life in patients with motor neurone disease: a qualitative exploration of family carer and health professional experiences.

BACKGROUND: Non-invasive ventilation improves quality and quantity of life in patients with motor neurone disease who have respiratory failure. Use of non-invasive ventilation may, however, result in complex clinical issues for end-of-life care, with concerns as to whether and how it should be withdrawn. AIM: This study aimed to describe carer and health professional experiences of end-of-life care of motor neurone disease patients using non-invasive ventilation. DESIGN/PARTICIPANTS: This article reports data from qualitative interviews with family carers and professionals following the death of patients with motor neurone disease who were using non-invasive ventilation in the final phase of the disease. RESULTS: Ten of the 20 patients initiated on non-invasive ventilation were using it in the end-of-life phase of their disease, with 5 using it for 24 h/day. Interviews were carried out with nine family carers and 15 professionals. Nine recurring themes were identified in the data. Both carers and health-care professionals perceived that the terminal phase of motor neurone disease was unexpectedly rapid and that this often led to unplanned interactions with the emergency services. Carers of patients who used non-invasive ventilation perceived non-invasive ventilation as aiding patient comfort and anxiety at the end of life. CONCLUSIONS: The use of non-invasive ventilation was described as beneficial and was not perceived by carers or most professionals to have adversely impacted patient's end-of-life experience. This study highlights variation in patient wishes regarding usage towards the end of life, uncertainty regarding appropriate management among professionals and the importance of disseminating end-of-life wishes.

The initiation of non-invasive ventilation for patients with motor neuron disease: patient and carer perceptions of obstacles and outcomes.

This study aimed to examine the experiences of patients with motor neuron disease and their carers following the recommendation to use non-invasive ventilation (NIV). Qualitative interviews were carried out with 20 patients and 17 carers within one month of NIV being initiated. The study identified a range of potential barriers to usage including: adverse impressions of the technology; sleep disturbance; the sensation of pressure and pulsing; dry mouth; and mask design issues. Patients/carers perceived benefits related to: increased energy; improved sleeping; enhanced carer well-being; improved breathing and increased speech clarity. A key factor described by patients and carers was the need to persevere to overcome the challenges associated with early NIV use. The study highlights the importance of patient perceptions of gains as a factor in their NIV usage decisions. While recognizing that older individuals with limb-onset disease were over-represented in the sample, key recommendations from the study are: availability of easily accessible in-person support for patients; for clinicians to pre-empt potential obstacles by discussing options such as humidification or alternative mask interfaces; the importance of discussing potential benefits in detail with patients; and optimization of secretion management prior to NIV trial.

Protocol for diaphragm pacing in patients with respiratory muscle weakness due to motor neurone disease (DiPALS): a randomised controlled trial.

BACKGROUND: Motor neurone disease (MND) is a devastating illness which leads to muscle weakness and death, usually within 2-3 years of symptom onset. Respiratory insufficiency is a common cause of morbidity, particularly in later stages of MND and respiratory complications are the leading cause of mortality in MND patients. Non Invasive Ventilation (NIV) is the current standard therapy to manage respiratory insufficiency. Some MND patients however do not tolerate NIV due to a number of issues including mask interface problems and claustrophobia. In those that do tolerate NIV, eventually respiratory muscle weakness will progress to a point at which intermittent/overnight NIV is ineffective. The NeuRx RA/4 Diaphragm Pacing System was originally developed for patients with respiratory insufficiency and diaphragm paralysis secondary to stable high spinal cord injuries. The DiPALS study will assess the effect of diaphragm pacing (DP) when used to treat patients with MND and respiratory insufficiency. METHOD/DESIGN: 108 patients will be recruited to the study at 5 sites in the UK. Patients will be randomised to either receive NIV (current standard care) or receive DP in addition to NIV. Study participants will be required to complete outcome measures at 5 follow up time points (2, 3, 6, 9 and 12 months) plus an additional surgery and 1 week post operative visit for those in the DP group. 12 patients (and their carers) from the DP group will also be asked to complete 2 qualitative interviews. DISCUSSION: The primary objective of this trial will be to evaluate the effect of Diaphragm Pacing (DP) on survival over the study duration in patients with MND with respiratory muscle weakness. The project is funded by the National Institute for Health Research, Health Technology Assessment (HTA) Programme (project number 09/55/33) and the Motor Neurone Disease Association and the Henry Smith Charity.

A survey to investigate shortfalls in the dental care professional (DCP) workforce in South Yorkshire in 2004.

AIM: To determine the composition of the dental care professional (DCP) workforce in South Yorkshire, the existence of any training requirements, and future intentions and motivations relating to the provision of National Health Service (NHS) dental care. METHODS: The study used mixed methods and incorporated a cross-sectional postal questionnaire and focus groups. The questionnaire was sent to all NHS dental practices in South Yorkshire (n=201) for completion by a principal general dental practitioner (GDP). Focus groups were held with GDPs in these practices. RESULTS: Responses were received from principal GDPs at 156 practices (78%). A total of 624 dental nurses, 65 dental hygienists and 24 dental therapists were employed in the responding General Dental Services (GDS) practices, representing whole-time equivalents (WTEs) of 458.5, 18.5 and 10.1, respectively. Many practices had current vacancies for DCPs, with 24.9 WTE available for dental nurses, 3.7 WTE for dental hygienists, and 5.0 WTE for dental therapists. Workforce shortages were evident among dental nurses (5.2%), dental hygienists (16.7%), and dental therapists (33.0%). Principal GDPs suggested that improved terms and conditions of employment for DCPs, particularly dental nurses, might aid recruitment and retention in NHS practice. CONCLUSIONS: Respondents perceived that there were shortages in the DCP workforce in South Yorkshire. Initiatives are required to address these shortages.
