Abstract
Objectives: To assess the quality assurance of a specialist palliative care clinic focused on chronic diseases and explore the satisfaction and acceptability of the telemedicine model amongst patients and caregivers.
Methods: A cross-sectional 23-item survey was developed by the clinical team, approved by ethics and distributed to patients and caregivers. Data collection ran between September 2021 and February 2022, and SPSS was used for data analysis. Demographics were collected from hospital records.
Results: Thirty-five surveys were returned. The cohort had a median age of 82 years, and the most common primary diagnosis was renal failure. Participants rated telemedicine as easier to access than face-to-face appointments due to convenience. Telemedicine was rated highly for future utility, with video consultations being perceived as more useful than telephone consultations. Participants responded overwhelmingly well towards the clinic.
Discussion: Findings demonstrated high levels of satisfaction with the Supportive Care Clinic model and for telemedicine. However, logistical challenges and the desire for face-to-face appointments were also identified. The study highlights the importance of offering a range of modalities for patient engagement in healthcare services and suggests that telemedicine should complement, rather than replace, face-to-face consultations. Future investigations should explore patient and caregiver sentiment towards telemedicine platforms alongside patient deterioration.

Background: Population preferences for care at the end of life can inform palliative care policy and direction. Research investigating preferences for care at the end of life has focused predominantly on the context of advanced cancer, with relatively little attention to other life-limiting illnesses that are common causes of death.
Objectives: We aimed to investigate preferences for the care of older people at the end of life in three different disease contexts. The purpose was to understand if population preferences for care in the last 3 weeks of life would differ for patients dying from cancer, heart failure or dementia.
Methods: Three discrete choice experiments were conducted in Australia with a general population sample using similar methods but different end-of-life disease contexts. Some attributes were common across the three experiments and others differed to accommodate the specific disease context. Each survey was completed by a different panel sample aged ≥45 years (cancer, n = 1548; dementia, n = 1549; heart failure, n = 1003). Analysis was by separate mixed logit models.
Results: The most important attributes across all three surveys were costs to the patient and family, patient symptoms and informal carer stress. The probability of choosing an alternative was lowest (0.18-0.29) when any one of these attributes was at the least favourable level, holding other attributes constant across alternatives. The cancer survey explored symptoms more specifically and found patient anxiety with a higher relative importance score than the symptom attribute of pain. Dementia was the only context where most respondents preferred to not have a medical intervention to prolong life; the probability of choosing an alternative with a feeding tube was 0.40 (95% confidence interval 0.36-0.43).
Conclusions: This study suggests a need for affordable services that focus on improving patient and carer well-being irrespective of the location of care, and this message is consistent across different disease contexts, including cancer, heart failure and dementia. It also suggests some different considerations in the context of people dying from dementia where medical intervention to prolong life was less desirable.

Introduction: Palliative radiotherapy (PRT) is frequently used to treat symptoms of advanced cancer, however benefits are questionable when life expectancy is limited. The 30-day mortality rate after PRT is a potential quality indicator, and results from a recent meta-analysis suggest a benchmark of 16% as an upper limit. In this population-based study from Queensland, Australia, we examined 30-day mortality rates following PRT and factors associated with decreased life expectancy.
Methods: Retrospective population data from Queensland Oncology Repository was used. Study population data included 22,501 patients diagnosed with an invasive cancer who died from any cause between 2008 and 2017 and had received PRT. Thirty-day mortality rates were determined from the date of last PRT fraction to date of death. Cox proportional hazards models were used to identify factors independently associated with risk of death within 30 days of PRT.
Results: Overall 30-day mortality after PRT was 22.2% with decreasing trend in more recent years (P = 0.001). Male (HR = 1.20, 95% CI = 1.13-1.27); receiving 5 or less radiotherapy fractions (HR = 2.97, 95% CI = 2.74-3.22 and HR = 2.17, 95% CI = 2.03-2.32, respectively) and receiving PRT in a private compared to public facility (HR = 1.61, 95% CI = 1.51-1.71) was associated with decreased survival.
Conclusion: The 30-day mortality rate in Queensland following PRT is higher than expected and there is scope to reduce unnecessarily protracted treatment schedules. We encourage other Australian and New Zealand centres to examine and report their own 30-day mortality rate following PRT and would support collaboration for 30-day mortality to become a national and international quality metric for radiation oncology centres.

Background: Growing global demand for palliative care services has prompted generalist clinicians to provide adjunct support to specialist teams. Paramedics are uniquely placed to respond to these patients in the community. However, embedding palliative care principles into their core business will require multifactorial interventions at structural, healthcare service and individual clinician and consumer levels.
Aim: To develop a palliative paramedicine framework suitable for national implementation, to standardise best practice in Australia.
Design: Delphi study utilising questionnaire completion; each round informed the need for, and content of, the next round. Free text comments were also sought in Round 1. Two rounds of Delphi were undertaken.
Setting/participants: Sixty-eight participants took part in Round 1, representing six countries, and 66 in Round 2. Participants included paramedics, palliative care doctors and nurses, general practitioners, researchers and carers with lived experience and expertise in palliative paramedicine.
Results: Seventeen of the original 24 components gained consensus; 6 components were modified; and 9 new components arose from Round 1. All modified and new components gained consensus in Round 2. Only one original component did not gain consensus across both rounds and was excluded from the final 32-component framework.
Conclusion: This study has developed a comprehensive national framework addressing the macro-, meso- and micro-level interventions required to standardise palliative paramedicine across Australia. Future research ought to engage a multidisciplinary team to create an implementation strategy, addressing any perceived barriers, facilitators and challenges for applying the framework into policy and practice.

Objective: The importance of early integration of palliative care in the management of complex multi-system diseases has been recognised. In this study, we aimed to quantify the need for specialist palliative care in systemic sclerosis (SSc).
Methods: Using data from 875 patients enrolled in the Australian Scleroderma Cohort Study, we defined need for palliative care as a high symptom burden at ≥2 consecutive study visits, ≥50% of overall study visits or at the study visit immediately prior to death. Symptoms of interest included breathlessness, fatigue, pain, depression, anxiety, constipation, and diarrhoea. Logistic regression analyses evaluated the association between individual symptoms and SSc manifestations. Linear regression analysis evaluated the relationship between palliative care needs and quality of life (QoL) and function.
Results: Almost three-quarters (72.69%) of patients met the threshold for specialist palliative care needs. Severe fatigue (54.17%) was most common, followed by breathlessness (23.66%) and severe constipation (21.14%). Concurrent severe symptoms were frequently observed. Severe breathlessness (coef -7.95, p<0.01) and pain (coef -7.70, p<0.01) were associated with the largest reductions in physical QoL. Severe mood symptoms were associated with the greatest reduction in mental QoL (coef -12.91, p<0.01). Severe pain (coef 0.56, p<0.01), breathlessness (coef 0.49, p<0.01) and mood symptoms (coef 0.40, p<0.01) had a significant impact on function.
Conclusion: SSc is frequently associated with multiple severe symptoms that may be amenable to palliative care intervention. Given the strong association between symptom burden and impaired QoL targeted, effective symptom management in parallel with standard-of-care treatments may improve overall patient outcomes.
