Optimizing patient autonomy in amyotrophic lateral sclerosis: inclusive decision-making in multidisciplinary care

Assessing the psychometric properties of quality of life measures in individuals with amyotrophic lateral sclerosis: a systematic review

PURPOSE

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease in adults. There are many patient-reported outcome measures (PROMs) for measuring quality of life (QoL) and health-related QoL (HRQoL) within this population; however, there is limited consensus regarding which are most valid, reliable, responsive, and interpretable. This systematic review assesses the psychometric properties and interpretability of QoL and HRQoL PROMs for individuals with ALS.

METHODS

This review was conducted following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology for systematic reviews of PROMs. MEDLINE, EMBASE, and CINAHL databases were searched. Studies were included if their aim was to evaluate one or more psychometric properties or the interpretability of QoL or HRQoL PROMs in individuals with ALS.

RESULTS

We screened 2713 abstracts, reviewed 60 full-text articles, and included 37 articles. Fifteen PROMs were evaluated including generic HRQoL (e.g., SF-36), ALS-specific HRQoL (e.g., ALSAQ-40), and individualized QoL (e.g., SEIQoL) measures. Evidence for internal consistency and test-retest reliability were acceptable. For convergent validity, 84% of hypotheses were met. For known-groups validity, outcomes were able to distinguish between healthy cohorts and other conditions. Responsiveness results ranged from low to high correlations with other measures over 3-24 months. Evidence for content validity, structural validity, measurement error, and divergent validity was limited.

CONCLUSION

This review identified evidence in support of the ALSAQ-40 or ALSAQ-5 for individuals with ALS. These findings can guide healthcare practitioners when selecting evidence-based QoL and HRQoL PROMs for patients and provide researchers with insight into gaps in the literature.

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.

Communication and cognitive impairments and health care decision making in MND: A narrative review

RATIONALE

Motor neurone disease (MND) is a neurodegenerative disease presenting with progressive weakness of voluntary muscles. For any condition, person-centred health care relies on the sharing of information and a mutual understanding of the person's needs and preferences. Decision making in MND becomes more complex as there is no cure and a high prevalence of co-morbid communication and/or cognitive difficulties.

OBJECTIVE

To identify the reported impact of communication and/or cognitive impairment on patient and carer involvement in health care decision making in MND.

METHODS

A review and synthesis of studies addressing issues of communication impairment and/or cognitive impairment in relation to decision making focussed on MND was conducted. Articles were excluded if they were reviews, case studies, conference papers, or commentaries. To be included studies needed to address issues of communication impairment or cognitive impairment specifically in relation to decision making. Relevant data were extracted verbatim and subjected to content analysis to support the narrative summary.

RESULTS

Seventy-six articles were identified, and 35 articles screened. Six articles met inclusion criteria each describing examples of decision making in MND. There was limited data related to communication and/or cognitive impairment, and the impact these impairments may have on decision making despite recognition that many people with MND may lose verbal communication or develop subtle cognitive impairments. The literature is primarily from the perspective of others.

CONCLUSION

This review highlights that the current body of literature exploring decision making within the MND population presents us with extremely limited insights into the impact of communication and/or cognitive impairments on health care decision making. Extant literature focuses on interventions (namely, ventilation and gastrostomy), the broad process of decision making, or cognitive assessment of decision-making ability. Whilst most studies acknowledge that deficits in communication or cognition impact the decision-making process, this issue is not the focus of any study.

Relational autonomy in breast diseases care: a qualitative study of contextual and social conditions of patients' capacity for decision-making

BACKGROUND

A relational approach to autonomy refers to the way in which social conditions and relationships shape a person's self-identity and capacity in decision-making. This article provides an empirical account of how treatment choices for women undergoing breast diseases care are fostered within the dynamics of their relationships with clinicians, family members, and other aspects of their social environment.

METHODS

This qualitative study recruited ten women undergoing treatment at a breast programme, and eight clinicians supporting their care, in a private teaching hospital in New South Wales, Australia. Fourteen patient-clinician consultation observations and 17 semi-structured interviews were conducted. Schema analysis of interview transcripts were undertaken by a team of researchers and corroborated by observational fieldnotes.

RESULTS

Relational identities of patients influenced the rationale for treatment decision-making. Patients drew on supportive resources from family and medical advice from clinicians to progress with treatment goals. While clinicians held much social power over patients as the medical experts, patients highlighted the need for clinicians to earn their trust through demonstrated professionalism. Information exchange created a communicative space for clinicians and patients to negotiate shared values, promoting greater patient ownership of treatment decisions. As treatment progressed, patients' personal experiences of illness and treatment became a source of self-reflection, with a transformative impact on self-confidence and assertiveness.

CONCLUSION

Patients' confidence and self-trust can be fostered by opportunities for communicative engagement and self-reflection over the course of treatment in breast disease, and better integration of their self-identity and social values in treatment decisions.

Communication Matters-Pitfalls and Promise of Hightech Communication Devices in Palliative Care of Severely Physically Disabled Patients With Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease, leading to progressive paralysis, dysarthria, dysphagia, and respiratory disabilities. Therapy is mostly focused on palliative interventions. During the course of the disease, verbal as well as nonverbal communicative abilities become more and more impaired. In this light, communication has been argued to be “the essence of human life” and crucial for patients' quality of life. High-tech augmentative and alternative communication (HT-AAC) technologies such as eyetracking based computer devices and brain-computer-interfaces provide the possibility to maintain caregiver-independent communication and environmental control even in the advanced disease state of ALS. Thus, they enable patients to preserve social participation and to independently communicate end-of-life-decisions. In accordance with these functions of HT-AAC, their use is reported to strengthen self-determination, increase patients' quality of life and reduce caregiver burden. Therefore, HT-AAC should be considered as standard of (palliative) care for people with ALS. On the other hand, the supply with individually tailored HT-AAC technologies is limited by external and patient-inherent variables. This review aims to provide an overview of the possibilities and limitations of HT-AAC technologies and discuss their role in the palliative care for patients with ALS.

Usability of eyetracking computer systems and impact on psychological wellbeing in patients with advanced amyotrophic lateral sclerosis

Restrictions in communicative abilities are well known in patients with amyotrophic lateral sclerosis (ALS), but only few approaches in terms of evaluation of supportive technologies have been made. We aimed to assess the use and perceived usability of eye-tracking computer devices (ETCS) of severely impacted patients with ALS in an independent, direct manner and relate it to psychological well-being. ETCS enable active communication and social participation in the quadriplegic and anarthric disease state. Therefore, ETCS-based versions of widely used psychosocial questionnaires (ADI-12, SeiQoL-DW, WHO-5) as well as structured questions on communicative functioning and ETCS usage were developed to assess ALS patients, their next of kin and professional caregivers. Eleven patients (ALSFRS-R: 5.3 ± 5.9; ALS duration: 6.5 ± 3.8 years, range 1‒12; 82% invasively ventilated), nine next of kin and 10 professional caregivers could be assessed. Patients reported a mean use of their personal ETCS of 9.1 h per d (range 0.5‒16), with a high user satisfaction, preservation of communicative abilities and subjective indispensability of the ETCS. ETCS use was associated with higher psychological well-being. Next of kin and professional caregivers also nominated some critical aspect, which remains to be clarified. Our results strengthen the evidence that preserved mental autonomy influences psychological well-being in ALS and might even modify disease course and end-of-life-decisions 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.
