Holding back in communications with clinicians: Patient and care partner perspectives in Parkinson's disease.

Objectives: To describe how patients with Parkinson's disease (PD) and care partners choose to share or withhold information from clinicians. Methods: This is a qualitative, descriptive study nested within a multisite, randomized clinical trial of outpatient palliative care compared to standard neurologic care for PD. Interviews with patients (n = 30) and care partners (n = 30) explored experiences communicating with neurology clinicians. Thematic analyses identified themes relevant to patient-care partner-clinician communication. Results: There were four themes relevant to sharing and/or withholding information from clinicians: (1) Suppressing Concerns During Visits, (2) Care Partner Awareness of Patients' Communication Barriers due to Cognitive Impairment, (3) Limited Sharing of Sensitive or Intimate Issues by Patients and Care Partners, and (4) Patient and Care Partner Suggestions to Overcome 'Holding Back'. Conclusion: Limitations to communication between patients, care partners, and clinicians should be acknowledged and recognized in routine Parkinson's disease care to foster accurate disclosure of unmet palliative care and other needs. Triadic communication strategies may help patients and care partners talk about unmet palliative care needs. Innovation: By recognizing that cognitive impairment and sensitive topics can be barriers, clinicians can adjust or adopt targeted communication strategies for identifying and discussing care needs.

Comparison of Integrated Outpatient Palliative Care With Standard Care in Patients With Parkinson Disease and Related Disorders: A Randomized Clinical Trial.

Importance: Parkinson disease and related disorders (PDRD) have consequences for quality of life (QoL) and are the 14th leading cause of death in the United States. Despite growing interest in palliative care (PC) for persons with PDRD, few studies are available supporting its effectiveness. Objective: To determine if outpatient PC is associated with improvements in patient-centered outcomes compared with standard care among patients with PDRD and their caregivers. Design, Setting, and Participants: This randomized clinical trial enrolled participants at 3 academic tertiary care centers between November 1, 2015, and September 30, 2017, and followed them up for 1 year. A total of 584 persons with PDRD were referred to the study. Of those, 351 persons were excluded by phone and 23 were excluded during in-person screenings. Patients were eligible to participate if they had PDRD and moderate to high PC needs. Patients were excluded if they had urgent PC needs, another diagnosis meriting PC, were already receiving PC, or were unable or unwilling to follow the study protocol. Enrolled participants were assigned to receive standard care plus outpatient integrated PC or standard care alone. Data were analyzed between November 1, 2018, and December 9, 2019. Interventions: Outpatient integrated PC administered by a neurologist, social worker, chaplain, and nurse using PC checklists, with guidance and selective involvement from a palliative medicine specialist. Standard care was provided by a neurologist and a primary care practitioner. Main Outcomes and Measures: The primary outcomes were the differences in patient quality of life (QoL; measured by the Quality of Life in Alzheimer Disease scale) and caregiver burden (measured by the Zarit Burden Interview) between the PC intervention and standard care groups at 6 months. Results: A total of 210 patients with PDRD (135 men [64.3%]; mean [SD] age, 70.1 [8.2] years) and 175 caregivers (128 women [73.1%]; mean [SD] age, 66.1 [11.1] years) were enrolled in the study; 193 participants (91.9%) were white and non-Hispanic. Compared with participants receiving standard care alone at 6 months, participants receiving the PC intervention had better QoL (mean [SD], 0.66 [5.5] improvement vs 0.84 [4.2] worsening; treatment effect estimate, 1.87; 95% CI, 0.47-3.27; P = .009). No significant difference was observed in caregiver burden (mean [SD], 2.3 [5.0] improvement vs 1.2 [5.6] improvement in the standard care group; treatment effect estimate, -1.62; 95% CI, -3.32 to 0.09; P = .06). Other significant differences favoring the PC intervention included nonmotor symptom burden, motor symptom severity, completion of advance directives, caregiver anxiety, and caregiver burden at 12 months. No outcomes favored standard care alone. Secondary analyses suggested that benefits were greater for persons with higher PC needs. Conclusions and Relevance: Outpatient PC is associated with benefits among patients with PDRD compared with standard care alone. This study supports efforts to integrate PC into PDRD care. The lack of diversity and implementation of PC at experienced centers suggests a need for implementation research in other populations and care settings.

Does outpatient palliative care improve patient-centered outcomes in Parkinson's disease: Rationale, design, and implementation of a pragmatic comparative effectiveness trial.

Patients with Parkinson's disease and related disorders (PDRD) and their families have considerable unmet needs including non-motor symptom management, caregiver support, spiritual wellbeing, advance care planning, and end-of-life care. There is increasing interest in applying palliative care (PC) models to better meet these needs. While PC has been shown to improve care and quality of life (QOL) for people with cancer and heart failure, few studies have evaluated the role of PC for people with PDRD. Well-designed clinical trials are needed to optimize the PC approach for PDRD and to influence policy and implementation efforts. We initiated a randomized multicenter comparative effectiveness trial of team-based outpatient PC versus usual care for people with PDRD and their caregivers. The primary aims of this study are to determine the effects of PC on patient QOL and caregiver burden. Qualitative interviews will be utilized to gain additional insights into the impact of PC on participants, the outcomes that matter most to this population, and to find opportunities to refine future interventions and trials. As a novel application of PC, challenges involved in the design of this study include choosing appropriate inclusion criteria, standardizing the intervention, defining usual care, and choosing outcome measures suitable to our research questions. Challenges involved in implementation include participant recruitment, retention, and management of participant burden. We anticipate the results of this trial will have relevance for both clinical care and future clinical research trial design in evaluating models of PC for people with PDRD and other serious illnesses.

Palliative care for Parkinson's disease: suggestions from a council of patient and carepartners.

In 2015, the Parkinson's Disease Foundation sponsored the first international meeting on Palliative Care and Parkinson's disease and the Patient Centered Outcomes Research Institute funded the first comparative effectiveness trial of palliative care for Parkinson's disease. A council of Parkinson's disease patients and carepartners was engaged to assist with both projects. This council wrote the following manuscript as an opinion piece addressed to the clinical and research community on how palliative care could be applied to people living with Parkinson's disease and their families. The council endorses palliative care as an approach to the care of Parkinson's disease patients and their families that seeks to reduce suffering through spiritual, psychosocial, and medical support. This approach should start at the time of diagnosis, as this is a very challenging time for patients and carepartners; includes better emotional support, educational resources, and closer follow-up than is currently standard; and continue through end-of-life care and bereavement.
