Objectives: The primary aim of this research was to use a taxonomy of behavior change techniques (BCTTv1) to identify, map, and describe the active components of intervention and comparator groups in studies evaluating the psychological well-being (PWB) of motor neuron disease (MND) carers. Secondary aims were to (a) identify absent active ingredients and (b) explore whether variability in the effectiveness of interventions targeting the PWB of MND carers could be better explained through improved characterization of the active content of these interventions.

Methods: Mixed-methods systematic review based on Joanna Briggs Institute methodology for quantitative, qualitative, and mixed-methods reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Content-coding of interventions targeting the PWB of MND carers using BCTTv1 was conducted.

Results: Sixteen manuscripts describing 14 studies were included. Forty-one of the possible 93 behavior change techniques (BCTs, 44%) were identified as active ingredients, while 52 BCTs (56%) were absent. BCTs were identified in all 14 intervention groups and 4 control groups. Four of the 16 overall BCTTv1 categories were absent. Eleven of the 14 studies demonstrated PWB benefits from their interventions.

Significance of results: Identified and absent BCTs and BCTTv1 categories were mapped for all study groups, enabling a transparent characterization of active intervention content associated with positive PWB outcomes. Directions to improve interventions in this nascent field of research included the investigation of relevant untested BCTs in this population and the management of reporting and methodological quality issues.

Objectives: Patients with advanced cancer experience varying physical and psychological symptoms throughout the course of their illness. Depression, anxiety and stress affect overall well-being. This study investigates the correlation between emotional distress and physical symptoms in a cohort of patients with advanced cancer.

Methods: There were 238 patients included in this study. Data from participants in two medicinal cannabis randomised controlled trials were analysed. Patients were aged over 18 years and had advanced cancer. Edmonton Symptom Assessment System, and Depression, Anxiety and Stress Scale (DASS-21) were assessed for all patients at baseline.

Results: Moderate-severe depression was reported in 29.8% and moderate-severe anxiety was reported in 47.9% of patients. The emotional subscales of DASS-21 (depression, anxiety, stress) correlated with total symptom distress score (p<0.001) and overall well-being (p<0.001). Depression was correlated with physical symptoms of fatigue, nausea, poor appetite and dyspnoea. Anxiety was correlated with fatigue and dyspnoea. Stress was correlated with fatigue, nausea and dyspnoea.

Conclusions: Depression, anxiety and stress were common in this population. The relationship between physical and psychological well-being is complex. A holistic approach to symptom management is required to improve quality of life in patients with advanced cancer.

Background: Tracheostomy ventilation in motor neurone disease is an uncommon life-sustaining treatment. Best practice is having a plan for ventilation withdrawal, but the literature to guide practice is limited. Case reports have documented standard doses of opioids and benzodiazepines used for sedation in such cases.

Case: A 49-year-old man was diagnosed with motor neurone disease in 2016. He commenced tracheostomy ventilation in 2018. In 2022 and 2023, planning was undertaken, at the patient's request, for withdrawal of tracheostomy ventilation at home, when he was no longer able to communicate with technology.

Case planning: Planning included Bispectral Index monitoring prior to cessation of ventilation, ensuring this only occurred when deep sedation was achieved. After ventilation withdrawal in 2023, a retrospective review of medications given and his level of sedation on monitoring was undertaken, with family consent.

Outcome: Ventilation withdrawal was initiated after deep sedation was achieved, 6 h after commencing subcutaneous infusions of morphine, midazolam, clonazepam and phenobarbital.

Lessons: Doses required to achieve acceptable sedation exceeded literature reports. Achieving deep sedation was a longer than expected process.

Conclusion: More research using an objective measure of sedation is required, as clinical assessment of sedation in this context is compromised.

Context: The demand of palliative care is increasing due to the aging population and treatment hesitancy or intentional avoidance compromises symptom management.

Objectives: To identify patient beliefs associated with medication hesitancy by using the theory of planned behavior (TPB) namely, attitudes, subjective norms, behavioral intention, and perceived behavioral control associated with medication hesitancy or intentional noncompliance by avoidance.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was followed to conduct a systematic literature search involving the CINAHL, Embase, MEDLINE, and PsycINFO databases from inception until March 2022. Hand-searched articles from reference lists and gray literature were included. Thematic analysis was conducted on qualitative data and triangulated with quantitative data.

Results: About 554 articles were retrieved from the literature search and 17 articles were included based on the eligibility criteria. Three subthemes that were identified under TPB constructs were attitude: negative attitude toward medications, passive attitude toward illness and inaccurate information about disease or medication; one subtheme was identified under subjective norms: perceived negative opinions from others; and one subtheme was identified under perceived behavioral control: perception of manageable symptoms. Quantitative data provided triangulation of qualitative findings related to fear of addiction and side effects, feelings of hopelessness, unclear direction and information, social stigma, endurable symptoms, and illness as determinants for medication avoidance.

Significance of Results: This systematic review highlighted some patient beliefs related to medication hesitancy or avoidance. Clinicians should take patient beliefs and concerns into consideration when creating treatment regimens for people receiving palliative care to optimize medication adherence and the quality of care.

Objectives: This pilot project replicated a self-compassion program to support health-care professionals in palliative care settings. We anticipated that undertaking this program would enhance participants' psychological well-being.

Methods: Participants were recruited by convenience sampling from palliative care services in an area of Melbourne, Australia. Because of the COVID-19 pandemic, the program was offered online and comprised six once-weekly gatherings. Three survey rounds with identical questions were conducted prior to, immediately after, and 3 months after the training. The surveys consisted of 6 scales: the Self-Compassion Scale, the Santa Clara Brief Compassion Scale, the Cognitive and Affective Mindfulness Scale, the Depression Anxiety Stress Scale, the Professional Quality of Life Scale, and the Interpersonal Reactivity Index Scale. Paired-sample t-test and repeated measures analysis of variance analyses were used to compare participant responses.

Results: Nine participants working in palliative care completed the training and 3 surveys and included qualitative responses. The experience was overwhelmingly positive. Self-compassion (F = 14.44; p < 0.05) and mindfulness (F = 18.44; p < 0.05) scores significantly increased post-training, were picked up in a short time and endured. The emotional state improved by compassion satisfaction, showing a positive improvement 3 months post-training, along with there being no changes in compassion satisfaction, burnout, and dispositional empathy.

Significance of Results: Participants all worked in a supportive environment, which encouraged self-care. Even against the pandemic difficulties, a short online program was effective, assisting participants to cultivate their inner resources in mindfulness and self-compassion. While a small sample size, expansion of the training may benefit the wider palliative care workforce.
