Experience matters: neurologists' perspectives on ALS patients' well-being

Tracheostomy ventilation in ALS: healthcare practitioner perspectives on quality of life and implications for decision-making

Objectives: This qualitative study aimed to increase understanding of how healthcare practitioners (HCPs) perceive quality of life for people with ALS who use tracheostomy ventilation (TV) and the extent to which such views inform discussions regarding future treatment and care. Methods: A thematic analysis was applied to data derived from online semi-structured interviews with a professionally diverse group of 24 HCPs with experience of supporting people with ALS to use TV. Results: Four main themes relating to TV use emerged: i) Positive benefits; ii) Risks and challenges; iii) Factors influencing HCP perspectives; iv) Concepts informing HCP discussions. HCPs acknowledged that TV has the potential to extend life but were concerned with prolonging a serious decline in physical and cognitive functioning. HCPs tried to identify the 'tipping point' between quantity and quality of life for the individual and their family, taking into account the likelihood of a higher burden of care. HCPs drew on prior experience to assess anticipated quality of life, yet most HCPs in the UK have limited experience of TV for this group. HCPs also drew on principles of person-centered care, patient autonomy and value for money to guide their approach to discussing TV. Conclusions: HCP experience of positive outcomes of TV can foster a more proactive approach to initiating conversations about its potential use. Sharing best practice and improving guidance for HCPs may support early and on-going future care planning and enable people with ALS to make choices which are informed and in their best interests.

Alterations of Fat and Ketone Body Metabolism in ALS and SMA-A Prospective Observational Study

BACKGROUND

Amyotrophic lateral sclerdosis (ALS) and spinal muscular atrophy (SMA) are motor neuron diseases associated with distinct metabolic alterations. ALS patients feature an increased resting energy expenditure (REE) causing weight loss and cachexia. In SMA, a disturbed utilization of free fatty acids has been described. These metabolic alterations negatively affect prognosis in both diseases. The objective of this study was to further characterize these changes to identify potential therapeutic targets.

METHODS

Between 11/2020 and 08/2022, 112 ALS patients, 77 SMA patients, and 50 controls were recruited in the Department of Neurology of Ulm University. Standardized blood and urinary samples were collected to analyze fat and ketone metabolism.

RESULTS

Ketone body levels were higher in ALS and SMA compared to controls. In both diseases, patients with higher BMI featured higher ketone bodies and free fatty acids compared to those with lower BMI, while in controls we found the opposite phenomenon. In SMA, more severe disease types were associated with higher ketone body levels. Compared to ALS, SMA patients featured higher ketone body and free fatty acid levels.

CONCLUSIONS

Our data suggest that already during early disease stages, ALS patients produce ketone bodies to compensate for the energy deficit. In SMA, on the other hand, the persistence of ketogenesis may indicate an upregulation of all available metabolic pathways for energy production due to the disturbance of fatty acid utilization. Therefore, the application of additional sources of energy, such as ketone bodies, might constitute a promising therapeutic option in both diseases.

Clinician Perspectives Highlight the Need for Early Dyadic Coping Skills for People Living With Amyotrophic Lateral Sclerosis

CONTEXT

A diagnosis of ALS can be challenging, and many people find ways to adapt. At the same time, emotional distress can arise early after an ALS diagnosis even when high quality multidisciplinary care is provided. When emotional distress occurs, it can become chronic over time, and can affect both the person living with ALS and their care-partner (together called a dyad).

OBJECTIVES

We set out to understand ALS multidisciplinary clinicians' perception of the challenges experienced by people with ALS and care-partners who experience emotional distress after diagnosis and potential benefits of a coping skills program to help these patients and their care-partners, Resilient Together-ALS (RT-ALS).

METHODS

We conducted semi-structured focus groups and individual interviews with 17 clinicians at the Sean M. Healey & AMG Center for ALS at MGH (N = 2 focus groups and five interviews) to elicit feedback on four domains: 1) Psychosocial Needs of ALS Dyads seen in the clinic; 2) Clinic Flow and Referral System to RT-ALS; 3) Clinic Partnership Approach in Support of RT-ALS; 4) RT-ALS Program Content and Manual Format. We conducted rapid data analyses for a time-efficient hybrid inductive-deductive thematic approach.

RESULTS

Clinicians noted that dyadic distress (distress experienced by both patient and their care-partner individually and as a unit), though not universal, is often present early after diagnosis. The response to the proposed program content (dyadic and individual coping skills) and structure (6 weekly virtual sessions delivered within about 2 months after diagnosis) was positive. Multidisciplinary clinicians emphasized the importance of a skills-based program for dyads experiencing elevated early emotional distress for which referral can be easily integrated within clinic flow so as not to not increase provider and dyad burden.

CONCLUSION

RT-ALS program content and structure is acceptable to clinicians. It is imperative to next seek further input from dyads about whether this type of program would be of interest and if yes, to pilot and refine the program for feasibility testing and then efficacy.

Understanding Quality of Life for People with Motor Neurone Disease Who Use Tracheostomy Ventilation and Family Members: A Scoping Review

Tracheostomy ventilation (TV) can increase survival time for people living with motor neurone disease (MND); however, the use of TV varies between countries. Concerns regarding anticipated quality of life (QoL) are among the reasons given by healthcare professionals for not recommending this intervention, yet little is known about QoL in this context. This scoping review was conducted to examine the evidence on QoL for those with MND who use TV and family members involved in their care. Using the methodological guidance of the Joanna Briggs Institute, 23 papers were identified for inclusion, and findings were inductively analysed to identify key themes. We found that people living with MND tend to rate QoL post TV more positively than anticipated by healthcare professionals or family members. QoL was found to be related to positive relationships and activities the person could maintain. Feeling able to make a choice and an adequate level of financial resources were also important factors. Family members tended to experience lower QoL, associated with the uncertainty surrounding an emergency procedure and the complexity of subsequently required care. More evidence on QoL from the perspectives of people with MND who use TV is needed to support decision making and inform guidance.

Towards clinical application of implantable brain-computer interfaces for people with late-stage ALS: medical and ethical considerations

Individuals with amyotrophic lateral sclerosis (ALS) frequently develop speech and communication problems in the course of their disease. Currently available augmentative and alternative communication technologies do not present a solution for many people with advanced ALS, because these devices depend on residual and reliable motor activity. Brain-computer interfaces (BCIs) use neural signals for computer control and may allow people with late-stage ALS to communicate even when conventional technology falls short. Recent years have witnessed fast progression in the development and validation of implanted BCIs, which place neural signal recording electrodes in or on the cortex. Eventual widespread clinical application of implanted BCIs as an assistive communication technology for people with ALS will have significant consequences for their daily life, as well as for the clinical management of the disease, among others because of the potential interaction between the BCI and other procedures people with ALS undergo, such as tracheostomy. This article aims to facilitate responsible real-world implementation of implanted BCIs. We review the state of the art of research on implanted BCIs for communication, as well as the medical and ethical implications of the clinical application of this technology. We conclude that the contribution of all BCI stakeholders, including clinicians of the various ALS-related disciplines, will be needed to develop procedures for, and shape the process of, the responsible clinical application of implanted BCIs.

Well-being on supportive techniques in amyotrophic lateral sclerosis: from neurologists' perspective

OBJECTIVE

To investigate intercultural neurologists' perception of well-being in patients with amyotrophic lateral sclerosis (ALS) using gastrostomy (PEG), non-invasive, and/or invasive ventilation (NIV/IV) and to analyse the determinants and impact on the management of the above medical interventions (MIs).

METHODS

The study was based on anonymous questionnaires addressing the clinical approach and personal attitude towards the use of PEG, NIV and IV in ALS patients completed by 465 neurologists: 228 from Germany and 237 from Poland.

RESULTS

The German and Polish neurologists estimated the quality of life in ALS patients using PEG and NIV as neutral, whilst low in individuals using IV. A regression model revealed an independent influence of palliative care training (PCT) and age on that attitude in the German group. Higher values of estimated patients' depressiveness on PEG, NIV and IV were found amongst the Polish neurologists. Marital status, experience in ALS and being a parent independently influenced the perception of patients' depressiveness in the German, whilst marital status, age and PCT were factors in the Polish group. Amongst German neurologists, a higher perception of patients' depressiveness in individuals using PEG, NIV and IV was linked to the later timing of the MIs discussion. In the Polish group, it was a lower estimation of QoL in patients using PEG.

CONCLUSION

Neurologists' perception of ALS patients' well-being on MIs reflects their demographic status, professional experience and potentially their cultural background. This perception plays an important role in the timing of MIs discussion, possibly influencing the decision-making process.

Quality of life and mental health in the locked-in-state-differences between patients with amyotrophic lateral sclerosis and their next of kin

For both patients with amyotrophic lateral sclerosis (ALS) and their next of kin (NOK), the maintenance of quality of life (QoL) and mental health is particularly important. First studies suggest significant discrepancies between QoL reports by patients and NOK, but little is known for advanced ALS stages. To address this issue, we screened 52 ALS patients in incomplete locked-in state (iLIS). Final results were obtained for 15 couples of iLIS patients and NOK. We assessed patients' and NOK's subjective QoL, depression and anxiety and NOK's caregiver burden. Gaze controlled questionnaires allowed direct assessment of patients. Patients and NOK self-reported comparable, mostly moderate to high levels of QoL. Of note, NOK indicated stronger anxiety symptoms. Higher anxiety levels in NOK were associated with stronger caregiver burden and reduced QoL. No significant misjudgment of patient's QoL by the NOK was evident, while patients overestimated NOK's global QoL. However, NOK with severe caregiver burden and depression symptoms gave poorer estimations of patients' QoL. This relationship is relevant, considering NOK's impact on life critical treatment decisions. While the daily time NOK and patient spend together was positively correlated with NOK's QoL and mental health, this was not reversely found for the patients. Our results suggest that NOK adapt less successfully to the disease and concomitant experience of loss and point to an urgent need for specialized psychosocial support. The findings emphasize the importance of direct psychological wellbeing assessment of both patients and NOK in clinical practice, enabled by eye-tracking technology for patients in iLIS.

Caregivers' View of Socio-Medical Care in the Terminal Phase of Amyotrophic Lateral Sclerosis-How Can We Improve Holistic Care in ALS?

Multidimensional socio-medical care with an early integration of palliative principles is strongly recommended in amyotrophic lateral sclerosis (ALS), but provided inconsistently. We conducted telephone interviews with 49 former caregivers of deceased ALS patients to examine their experience of care in the terminal phase including caregiver burden. Patients who received specialized palliative care (45% of patients) were more likely to die at home (p = 0.004) and without burdening symptoms (p = 0.021). The majority of caregivers (86%) reported deficits in socio-medical care. Most frequently mentioned were problems receiving medical aids (45%) and a lack of caregiver support (35%). A higher level of deficits experienced by caregivers was associated with negative health outcomes on the side of the caregivers (reported by 57% of them; p = 0.002) and stronger caregiver burden (p = 0.004). To provide good quality of dying to patients and reduce the burden on caregivers, multidimensional—including palliative—care in ALS urgently needs to be strengthened in the healthcare structures.

Brain Computer Interfaces for Assisted Communication in Paralysis and Quality of Life

The rapid evolution of Brain-Computer Interface (BCI) technology and the exponential growth of BCI literature during the past 20 years is a consequence of increasing computational power and the achievements of statistical learning theory and machine learning since the 1960s. Despite this rapid scientific progress, the range of successful clinical and societal applications remained limited, with some notable exceptions in the rehabilitation of chronic stroke and first steps towards BCI-based assisted verbal communication in paralysis. In this contribution, we focus on the effects of noninvasive and invasive BCI-based verbal communication on the quality of life (QoL) of patients with amyotrophic lateral sclerosis (ALS) in the locked-in state (LIS) and the completely locked-in state (CLIS). Despite a substantial lack of replicated scientific data, this paper complements the existing methodological knowledge and focuses future investigators' attention on (1) Social determinants of QoL and (2) Brain reorganization and behavior. While it is not documented in controlled studies that the good QoL in these patients is a consequence of BCI-based neurorehabilitation, the proposed determinants of QoL might become the theoretical background needed to develop clinically more useful BCI systems and to evaluate the effects of BCI-based communication on QoL for advanced ALS patients and other forms of severe paralysis.

Caregivers' divergent perspectives on patients' well-being and attitudes towards hastened death in Germany, Poland and Sweden

Background: During the course of amyotrophic lateral sclerosis (ALS), patients and their families are faced with existential decisions concerning life-prolonging and -shortening measures. Correct anticipation of patient's well-being and preferences is a prerequisite for patient-centered surrogate decision making. Methods: In Germany (N = 84), Poland (N = 77) and Sweden (N = 73) patient-caregiver dyads were interviewed. Standardized questionnaires on well-being (ADI-12 for depressiveness; ACSA for global quality of life) and wish for hastened death (SAHD) were used in ALS patients. Additionally, caregivers were asked to fill out the same questionnaires by anticipating patients' perspective (surrogate perspective). Results: Caregivers significantly underestimated patients' well-being in Germany and Poland. For Swedish caregivers, there were just as many who underestimated and overestimated well-being. The same was true for wish for hastened death in all three countries. For Swedish and Polish patients, caregivers' estimation of well-being was not even associated with patients' responses and the same was true for estimation of wish for hastened death in all three countries. Older caregivers and those with the most frequent encounter with the patient were the closest in their rating of well-being and wish for hastened death to the patients' actual state, while caregivers with chronic disease him/herself were more likely to underestimate patient's well-being. Discussion: Despite distinct cultural differences, there was a clear discrepancy between patients' and caregivers' perspective on patients' well-being and preferences towards life in all three countries. This possible bias in caregivers' judgment needs to be taken into account in surrogate decision making.

Disease progression but not physical state per se determines mental wellbeing in ALS

Background

Studies provide inconclusive results on the question whether loss of mental wellbeing is actually associated with decline in physical function in amyotrophic lateral sclerosis (ALS). The purpose of this study was to determine predictors of mental wellbeing in ALS.

Methods

In total, n = 330 ALS patients were interviewed on parameters of mental wellbeing to evaluate the patients’ capacity of psychosocial adaptation. These parameters were global and subjective quality of life (QoL), and depressiveness. A subsample of n = 82 ALS patients were interviewed again within approximately a year (mean 14.34 ± 5.53 months).

Results

Both global and subjective QoL were stable, whereas depressiveness increased within the course of 1 year after diagnosis. Physical function decline was associated with mental wellbeing. Progression of physical disabilities and symptom duration were significant predictors of wellbeing in the sense that fast progression and short time since symptom onset (both indicating short time to adapt) were associated with low wellbeing.

Conclusions

There is evidence for subsamples in ALS with regard to mental wellbeing, which are mainly determined by clinical parameters. Those subjects being reported in the literature to present with high mental wellbeing are often long survivors. High progression rate and low physical function when attending the clinic for the first time should be red flags and need special attention in clinical counseling.

Beatmung bei neuromuskulären Erkrankungen

Neuromuskuläre Erkrankungen betreffen das erste und zweite Motoneuron, die peripheren Nerven, die neuromuskulären Übertragung und die Muskelzelle. Es handelt sich um eine heterogene Gruppe von erblichen, degenerativen und autoimmunen Erkrankungen. Eine korrekte diagnostische Einordnung ist erforderlich, da zentralnervöse, kardiale, endokrine und weitere Begleitsymptome vorliegen können und für einige Erkrankungen bereits medikamentöse Therapien zur Verfügung stehen. Neuromuskuläre Erkrankungen haben eine große Bedeutung in der neuromuskulären Beatmungsmedizin. Die respiratorische Symptomatik resultiert in der Regel aus Paresen der am Atmen, Schlucken oder Husten beteiligten Muskulatur mit konsekutiver ventilatorischer Insuffienz, Dysphagie bis hin zur Speichelaspiration und Sekretretention. Mittels eines strukturierte Sekretmanagements und einer effektive nichtinvasive oder invasive Beatmungstherapie können neuromuskuläre Patienten viele Jahre mit guter Lebensqualität überleben. Themen dieses Kapitels sind ein Überblick über die neuromuskulären Erkrankungen, die Indikationen und Strategien der nichtinvasiven und der invasiven Beatmung und eine ausführliche Darstellung beatmungsmedizinisch besonders relevanter neuromuskulärer Erkrankungen wie der amyotrophe Lateralsklerose, des Guillain-Barré-Syndroms, der Myasthenia gravis und der Critical-Illness-Polyneuropathie/-Myopathie.

An observational study on quality of life and preferences to sustain life in locked-in state

OBJECTIVE

This is an observational study on well-being and end-of-life preferences in patients with amyotrophic lateral sclerosis (ALS) in the locked-in state (LIS) in a Polish sample within the EU Joint Programme-Neurodegenerative Disease Research study NEEDSinALS (NEEDSinALS.com).

METHODS

In this cross-sectional study, patients with ALS in LIS (n = 19) were interviewed on well-being (quality of life, depression) as a measure of psychosocial adaptation, coping mechanisms, and preferences towards life-sustaining treatments (ventilation, percutaneous endoscopic gastroscopy) and hastened death. Also, clinical data were recorded (ALS Functional Rating Scale-revised version). Standardized questionnaires (Anamnestic Comparative Self-Assessment [ACSA], Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), ALS Depression Inventory-12 items [ADI-12], schedule of attitudes toward hastened death [SAHD], Motor Neuron Disease Coping Scale) were used, which were digitally transcribed; answers were provided via eye-tracking control. In addition, caregivers were asked to judge patients' well-being.

RESULTS

The majority of patients had an ACSA score >0 and a SEIQoL score >50% (indicating positive quality of life) and ADI-12 <29 (indicating no clinically relevant depression). Physical function did not reflect subjective well-being; even more, those with no residual physical function had a positive well-being. All patients would again choose the life-sustaining techniques they currently used and their wish for hastened death was low (SAHD <10). Caregivers significantly underestimated patient's well-being.

INTERPRETATION

Some patients with ALS in LIS maintain a high sense of well-being despite severe physical restrictions. They are content with their life-sustaining treatments and have a strong will to live, which both may be underestimated by their families and public opinion.

Interprofessional Care for Neuromuscular Disease

PURPOSE OF REVIEW

This review aims to delineate interprofessional care models for neuromuscular disease. Evidence regarding both the benefits and barriers to interprofessional neuromuscular care in both inpatient and outpatient settings is presented. Finally, opportunities to improve both access to and quality of care provided by interprofessional team clinics will be discussed.

RECENT FINDINGS

Although the term "multidisciplinary" is often misapplied to denote any interprofessional team-based care setting, there are important differences in team structure and dynamics in each of the three most common models: multidisciplinary, interdisciplinary, and transdisciplinary care. Evidence favors the more integrated interdisciplinary and transdisciplinary models for better patient outcomes and decreased staff burnout. Coordinated interprofessional care results in improved health outcomes, resource utilization, and patient satisfaction for persons with adult and pediatric neuromuscular disease. Distance remains the greatest barrier to specialized team-based care for this population; telehealth technologies may make interprofessional care more accessible to these persons. Despite limited evidence for the broader population of persons with neuromuscular disease, consensus guidelines increasingly support this model of care delivery. Further work may help determine effectiveness for other populations of persons with neuromuscular disease and best practices within these team-based models of care.

Non-invasive ventilation in amyotrophic lateral sclerosis

Non-invasive ventilation (NIV) has become an important cornerstone of symptomatic treatment in amyotrophic lateral sclerosis (ALS), improving survival and quality of life. In this review, we summarize the most important recent developments and insights, including evidence of efficacy, indication criteria and time of initiation, ventilation parameters and adaptation strategies, treatment of complicating factors, transition from NIV to invasive ventilation, termination of NIV and end-of-life management. Recent publications have questioned former conventions and guideline recommendations, especially with regard to timing and prognostic factors; therefore, a fresh look and re-evaluation of current evidence is needed.

Ethical Principles in Patient-Centered Medical Care to Support Quality of Life in Amyotrophic Lateral Sclerosis

It is one of the primary goals of medical care to secure good quality of life (QoL) while prolonging survival. This is a major challenge in severe medical conditions with a prognosis such as amyotrophic lateral sclerosis (ALS). Further, the definition of QoL and the question whether survival in this severe condition is compatible with a good QoL is a matter of subjective and culture-specific debate. Some people without neurodegenerative conditions believe that physical decline is incompatible with satisfactory QoL. Current data provide extensive evidence that psychosocial adaptation in ALS is possible, indicated by a satisfactory QoL. Thus, there is no fatalistic link of loss of QoL when physical health declines. There are intrinsic and extrinsic factors that have been shown to successfully facilitate and secure QoL in ALS which will be reviewed in the following article following the four ethical principles (1) Beneficence, (2) Non-maleficence, (3) Autonomy and (4) Justice, which are regarded as key elements of patient centered medical care according to Beauchamp and Childress. This is a JPND-funded work to summarize findings of the project NEEDSinALS (www.NEEDSinALS.com) which highlights subjective perspectives and preferences in medical decision making in ALS.

Amyotrophic lateral sclerosis: improving care with a multidisciplinary approach

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, leading to death within an average of 2–3 years. A cure is yet to be found, and a single disease-modifying treatment has had a modest effect in slowing disease progression. Specialized multidisciplinary ALS care has been shown to extend survival and improve patients’ quality of life, by providing coordinated interprofessional care that seeks to address the complex needs of this patient group. This review examines the nature of specialized multidisciplinary care in ALS and draws on a broad range of evidence that has shaped current practice. The authors explain how multidisciplinary ALS care is delivered. The existing models of care, the role of palliative care within multidisciplinary ALS care, and the costs of formal and informal care are examined. Critical issues of ALS care are then discussed in the context of the support rendered by multidisciplinary-based care. The authors situate the patient and family as key stakeholders and decision makers in the multidisciplinary care network. Finally, the current challenges to the delivery of coordinated interprofessional care in ALS are explored, and the future of coordinated interprofessional care for people with ALS and their family caregivers is considered.
