Immediate versus delayed short-term integrated palliative care for advanced long-term neurological conditions: the OPTCARE Neuro RCT

[Palliative neurology]

Palliative medicine represents the holistic multiprofessional treatment of severely and incurably ill people and their relatives, addressing their complex physical, psychological, social and spiritual needs. The central therapeutic goals are the quality of life and alleviation of suffering. In the course of many neurological diseases, high symptom burden, long and variable trajectories and unfavorable prognosis at times create a need for palliative care even at an early stage, which is currently still inadequately met. This can be countered by qualified neuropalliative care. In addition to intensifying interdisciplinary collaboration, this requires neurologists to have core competencies in palliative care. These include a team-oriented attitude, communication skills, expertise in symptom control and knowledge of biomedical ethics including palliative options at the end of life.

Palliative Care Interventions for Persons With Neurodegenerative Disease: A Scoping Review of Clinical Trial Study Design Features

Background: Within palliative care research, best practice guidelines to conduct scientifically rigorous clinical trials for neurodegenerative diseases are underexplored. This patient population experiences unique challenges, including fluctuations in cognitive capacity, care partner (CP) and proxy involvement, and high adverse events (AEs), that necessitate special consideration when designing clinical trials. Objective: The objective of this study was to describe and identify clinical trial design features that have been documented in studies involving a neuropalliative intervention for persons with neurodegenerative diseases, highlighting features that have been adapted for this unique patient population. Design: We conducted a scoping review of clinical trials with a neuropalliative intervention for persons with neurodegenerative disease. We searched Cochrane, Web of Science, EMBASE, Scopus, and PubMed (MEDLINE) databases for articles published in English between 1950 and 2023. Two reviewers screened, extracted, and synthesized data from the included articles. A third reviewer adjudicated instances of conflict. The data were analyzed using a thematic framework approach. Results: Of 1025 texts, 44 articles were included. Seven study design features were analyzed: (1) consent, (2) proxies and CPs, (3) recruitment strategies, (4) retention strategies, (5) choice of comparator, (6) AEs, and (7) internal validity. This scoping review found disparities in study design features around structured consent, proxies and CPs, comparators, and AEs. Conclusions: To date, neuropalliative care clinical trials have had varied study designs and the majority of research has focused on dementia. Research guideline development for high-quality neuropalliative care clinical trials is greatly needed across the range of neurodegenerative diseases. To increase the scientific rigor of clinical trials and neuropalliative care, we recommend a standardized capacity assessment for consent, defining conditions for the CP, proxy, and AEs, systematizing appropriate comparators, and outlining preemptive recruitment and retention strategies to address the broader unpredictable challenges of palliative care research.

The Medical Needs and Characteristics of Cancer and Progressive Neurologic Disease Patients Who Use Home-Based Medical Care in Korea: A Retrospective Study for 2011-2020

OBJECTIVES

To investigate the needs and characteristics of patients with cancer and neurologic disorders requiring home-based medical care (HBMC).

DESIGN

Retrospective observational study.

SETTING AND PARTICIPANTS

Patients receiving HBMC on discharge from a tertiary hospital in Korea during 2011-2020.

METHODS

Patients were classified into 3 disease groups: cancer, progressive neurologic disorders (NR), and others. Characteristics and medical needs were assessed in each disease group. Medical needs were categorized based on functional items requiring support or management at the time of registration: respiratory, feeding, urinary system, drain tube, central catheter, wound, medication, and other. Patients with multiple medical needs were assigned to multiple categories. Patients who used HBMC for more than 3 months were defined as long-term users; their characteristics were evaluated in the same way.

RESULTS

Of the total 655 patients, 47.0% (308) had cancer and 17.3% (113) were NR patients. Among all patients, 78.8% were partially dependent (44.0%) or completely dependent (34.8%) in daily activities, and there were more dependent patients in the NR group (80.5%) than cancer (26.6%). Patients with cancer needed central catheter management the most (43.5%), followed by wound care (36.7%), feeding support (35.1%), and drain tube management (22.1%). NR patients required feeding support the most (80.5%), followed by respiratory support (43.4%), wound care (41.6%), and urinary system support (19.5%). Of all patients, 30.2% (198) were long-term users (NR, 37.9%; cancer, 35.4%). Long-term users were common among patients who needed respiratory support (59.4%), feeding support (48.75), and urinary system support (34.6%).

CONCLUSIONS AND IMPLICATIONS

Homebound patients with cancer and progressive neurologic disorders need medical services at home after discharge. Patients who need feeding and respiratory support usually use HBMC for more than 3 months. Further studies are needed to design an optimal HBMC that continuously provides medical services to patients with serious illnesses living at home.

Palliative Care Intervention Trials for Adults Living With Progressive Central Nervous System Diseases and Their Caregivers: A Systematic Review

CONTEXT

Interest in implementing palliative care for adults living with progressive central nervous system diseases (PCNSD) and their caregivers is increasing.

OBJECTIVES

To inform evidence-based practice and future research by critically evaluating randomized clinical trials (RCTs) investigating palliative care interventions (PCIs) for adults living with PCNSD and their caregivers using self-reported outcomes and the patient- and caregiver-reported outcome measures employed.

METHODS

A systematic search using PRISMA methods of EMBASE, PubMed, Scopus, Web of Science databases using index and keyword methods for articles published from inception through February 28, 2021 was performed. RCTs investigating PCI as their primary aim using patient- and/or caregiver-reported outcomes to assess PCI effectiveness in adults living with PCNSD and their caregivers were included for qualitative synthesis.

RESULTS

Five RCTs met criteria and used 21 unique outcome measures. Pooled patient diagnoses included multiple sclerosis, motor neuron disease and movement disorders, primarily Parkinson's Disease. All five RCTs assessed PCI effectiveness on patient symptom burden and caregiver burden, and three RCTs used patient QOL as a primary outcome. Overall risk of bias was low. Pooled positive findings were limited to very modest changes in patient QOL, specific physical symptoms and caregiver burden. Most outcome measures lacked clinimetric responsiveness to detect change whether caused by disease or an intervention to the patient or caregiver.

CONCLUSION

Sparse, low-certainty evidence for PCI impact on patient QOL, symptom burden and caregiver burden indicate future research should consider refining study populations, interventions, outcomes assessed and outcome measures to detect any change due to PCI.
